6 lever 108 by the cam 200. This position of the lever 120 is utilized to force a springpressed pin 222 which is carried by a rearward extension 224 frol the lever 120 and guided in the framebracket, iiito a depression 226 in a 8urface 228 on the upper side of the hand-lever 126, adjac6nt to its fulcrum 128. This is as appears in Mg. 6, the hand-lever being found locked if the operator attempts to move it. Upon actuation of io the treadle and the release of the lever 108 by the cam 200, the spring 124 turns the lever 120 anticlockwise until the roll 123 contacts with the cam 122. This lifts the pin 222 from the depression ' unlocking the hand-lever. A heel having been nailed on a jacked shoe as a consequence of the operation of the treadle, and the completed work removed from the Jack, the operator may shift the hand-lever to cause the delivery to the ia6k by the load6r-blook L of the nails which were 20 @eceived by the latter from the nail-roll 96 upon the treadle-depression. The hand-lever is held in its actuated position by a rotating surface 230, while the cam 122 turns through 360', as in the previously mentioned Beni'amin patent. The 25 cam, acting upon the lever 120, again forces dow-n the pin 222, but the movement of the hand-l,,ver has carried away the depression 226, so said pin rides on the lever-surface 228 without interference *ith the movement of the lever. At the 30 terniination of the cycle, the lever 126 is released from the surface 230 and returned to its initial i@osition by the spring i29, and when it arrives there, the piri enters the depression to again lock the lever. Therefore, the operator cannot shift 3,3 the hand-lever to produce another nail-delivery or a nail-transfer until the preceding load has been driven out of the jack. In connection with the control o@' nail@-delivery by the feelers 156, tl-iis locking of the lever has at least two ad,40 vantages. The clutch of the mechanism C cannot be engaged, and therefore no harmful force can be applied to the feelers by movement of the nail-roll 96 under 'the power of the apparatus. Then, since the operator cannot move the hand45 lever from its normal position, he is more promptly notified that there is-a condition which must be corrected, and there is economy of eff ort.

Patented Nov. 28, 1939 2,18@1,139 UNITED STATES PATENT. OFFICE 2,181,139 FASTENING-SUPPLY]ING APPARATUS', John T. Lancaster, N@wton, Mass., assignor to United Shoe Machinery Corporation, Borough of Flemington, N. J., a corporittion of New Jersey AppUcation May 21.1938, Serial No. 205,497 107 Claims. My invention relates to apparatus by which fastenings are supplied in loads of one or more in number to a machine by which such fastenings are to be inserted, it being especially, directed to the delivery of nails br the like in sticee-.sive groups, fro--i a mass contained in a receptacle forming a part of a distributor and advanced therefrom by the loading means of this a])paratus to the receivl-ng macl-iine. 10 Because of irregularities in the frrrq of nails, it is difficult to insure, their delivery by automatic means in full groups or loads. W-lien a load with, a missiilg nail or.r-.ails is -fed i-iito a loading device for transfer to a rnochine for attaching heels to i @5 shoes it is liecess,ary that iricompieie loads be note@, and the defect corrected. If tl-iis is not possible, the work produced is fatlity. If each load can be inspected, and the niissing nails supplied, i-t produces a substantial loss of time. It is 20 a-i object of my invention to guard ,igainst the deli,7ery of a pqrtial iced. I-@i the attainmeiit of this object, I test each load or group of fastenings to determine its completeness by means acting between means whicl--l separates the loads 25' from the mass ond -rqeans @,vhich delivers said loads to the machine to be su,,oplied. Unless there is a full load, its delivery is impossible, and the operator needs only to provi.de the fastenings '7@'nich the a-pparatus i-tself hz@s determined I to be in@issed. Under r-o conditions can a partial load be fed. Preferably, a distributiiig or loadind mew-b@e-r, as an oscillatc)ry roll provided with@ a fastening-receiving passage stii3plied from a raceway, temporarily holds the fostenings during their :25 delive.,,y to the machi-ne to be supplied. A coop-a-,ati-'-Qg testing rileans or feeler, affected by the abser.l.ce of a fasteni-ng or fastel-lings at the holder, controls tlaeir delivery and the operation of the machilie to be slippli--d, thus preventing their use. The roll or other holder is preferiibly movable 40 in a casing having delivering, receiviiig and tl-stLlig openings for the faste,.iirgs, into registrati-On v7ith which op-.nings the holder-passage may be ri,ioved. In tl,,As r@i.ovemer-it, the holder may invert 45 the fastbr-ling contaii,,ed the passage. T6 deterro-ine the positio-n of the holder-roll, a device, as a -rotatable catp, is pro,7ided for coiitrolling ro'@@at-ion to certain of i-ts ijositions, as those for receiving a--(id testing, there 'o@eiiig associated with 50 this dei7ice other means for turiling the roll to its dblil,,ering position. A meniber movabib by the operator controls. the rotatio-n of the roll th-rough the cscillation 6f a prir-.iary ',ever, and the other me@ins by whiclii the roll is tiirned i-s governed by 55 a r-.--.eniber rnova'ole tlarc,,igh a secondary lever in the conlu_rol of '@he i'vachine suppli6d wilh fas@,enings. Ir@ the operation of the secondary lever, moveineiit is also im-narted to a member wb-ich goverias the movemer-t of the prirnary lever, which 60 it reieases for the shifting of the fastening-roll (Cl. 1-39) frbm the testing to tl-ie delivering position. In the illustrative form of the invehtion, the controlling means for tl-ie testing member consists of two disks, one @rotbtable with or as a part of the holder-roll and the other rotatable relatively thereto. Ir. the periphery of each disk is a dopression, and when these depressions are in registration, a lever or like member acting upon, tho feeler or feelers may enter said deliressions to produce the testing offect. There is means, as a,@l@( cam-incline tipon the. periphery of one of 'the disks, for removing the lever from the depressions. This withdraws the j'eeler from the roll-passage and p@epares for the rotation of the rbll after the testing has been performed. When the feeler 1.5 fails to find a nail, in the passage, it actuates a stop member, which both prevents operation of the machine which the apparatus supplies and, the m6vement of the disks or other coiitrolling means which would permit fasteningdelivery,c.)o from the roll. The inserting operation therefore cannot proceed until A full load of nails is ready for delivery. To facilitate the introduction into 'the holding-passage of a missing fastening, a loading member movable by thb operator is pro- 25 vided. Th@e holding-pasgage preferably extends through the roll, and the automatically operated -testihg means is movable into one end thereof, while, at the opposite end, the manually opera ed t loading means mOy introduce fastenings into the passage. I have shown this manual lo ng 3@o means, as I in the @ form of a rod,@ @tiided to recip-, rocate in an opening: in the casing iii which the holder-roll is rotatable. A slot admits a nail to the opening,. whereupon @ movement ' of the rod 35 carri6s the nail into the - roll-passage and forces 6ut the feeler, which found,such passage empty. In its inw I ard position, which is the normal or operatin g relation, the loader@rod is latched., Means movable with the rod closes the fastening -'40 receiving slot against the entrance of dirt illthis norrilal position. To guard against, the delivery of a double load of fastenings@ by the apparatus, the operator-actuated @member, 'which conttols the movement of the holding a,-id delivering mem - 45 ber and of a transferring device, has means for locking it against movement by the operator, this lock being released ',,as a result of the move-. ment of a second operator-governed member, as one movable in the control of the maebine sup-: 50 plied by the apparatus. . As particulatly disclosed herein , a rotatable cam operates- the nail-roll Ihrou gh a lever which initially is out of engagement with the cam and, which is goverr-ed@ by a handlever. A lock retaihs the hand-I.ever 55 against movement. under the control, of the camlever in its initial r6lation, and this lock is re-, moved when the.cam-levei7 is released for engagem ent with the cam. The releas,e is effected in the control of the machin6 supplied, so.the de- 60

2 livery of A load of nails may be produced only after the machine has utilized the preceding load. Another object of the invention is to maintain from a mass of nails or other fastenings in the distributing portion of the apparatus, a regular supply, by simple and effective means, and in such a manner that a plurality of sizes may be fed simultaneously. For t . his purpose, there is 10 rotatable in a stationary receptacle disks fixed to a shaft and provided with elevating buckets delivering to raceways, these buckets being shown as staggered upon opposite sides of the disks. The disks divide thereceptacle into separate com15 partments, in each of which fastenings differing in size or form from those in other compartments may be held. A cover is shown as hinged upon the receptacle, having a portion extending over each of the one or more raceways to protect 20 these. To free the raceway or raceways from crossedfastenings, rotatable clearing means is carried by the cover, gearing which turns the shaft and disks also rotating the clearing means. A further object of the invention is to pick 25 off accurately, one by one, for delivery from each raceway, successive fastenings. For this purpose, I employ a member movable at the end of a raceway and baving a flexible projection arranged to engage the terminal fastening and separate 30 it from the raceway. This projection is preferably in the form of a spring-wall, which is at the outer side of a recess in the wall of an oscillatory cylinder contained in a casing at the end of the raceway. The fastening-engaging end of the proSIS jection is inclined downwardly and rearwardly with respect to the direction of separating movement. Such a separator will yield without clogging or breaking, if it does not engage the f astenings in the best relation, and will gradually 40 straighten fastenings which have become inclined from the vertical. In its separation, a fastening enters a space between the end of the o-Liter or flexible wall and the wall furnished by the recess in the cylinder and is drawn off from the raceway 45 by the outer wall. TI-ie fastening is then carried by the end of the recess to a delivery-opening in the casing, such opening being larger than the head of the nail. Each of the separating cylinders for plural raceways is rotated by a yieldable con50 nection between it and its actuating means. In the present instance, there is a toothed member, as a rack-block, meshing with the teeth upon each cylinder, there being a, reciprocatory actuating member common to the toothed members. 55 The movement of the common actuating member is transmitted to the various toothed members or blocks through springs, so breakage is avoided if clogging occurs. I have illustrated herein a cover for each of the casings enclosing the separating 6( cylinders, this cover being hinged upon the projection from the receptacle-cover, which exte@nds over the raceway. In the accompanying drawings, which illustrate one of the many possible embodiments of 65 this invention: Fig. I shows my improved apparatus in side elevation in place upon the column of a heelattaching machine; 70 Fig. 2 is an elevation, viewing the apparatus from the front; Fig. 3, a top plan view; Fig. 4, an enlarged top plan view of one of the nail-separating cyliitders and the ad.jacent portion of the raceway; Fig. 5, a vertical longitudinal section through the same elements as appear in Fig. 4; Fig. 6, an enlarged, vertical, sectional detail through the nail-delivering mechanism, with the nail-roll in testing position; 5 ]@ig. 7, a similar view, with the elements in delivering position; Fig. 8, a like view of the nail-roll and more closely associated elements, illustrating the manner of introducing a missing nail into the roll; 10 Fig. 9, a sectional detail on the line IX-IX of Fig. 8, and Fig. 10, a detail in perspective of the actuating means for the nail-roll. The body or frame of the apparatus may be in 15 the form of an integral casting having a baseportion IO, by which it is mounted upon the top of the frai-ne of the heeling maclline F, the jack of which is to be supplied with nails in successive loads. Above the base is a semicylindrical trough 2 ' 0 12 (Fig. 1), which provides the lower half of a nail-drum or receptacle of a distributor. At the forward, side of the trough are downwardly inclined extensions 14 spaced from one another, upon which raceway-bars 16 are secured. prom 25 the forward extremity of each portion 14, shown therewith as a part of the base-casting, extend short, horizontal arms IO. In each of the arms is a vertical bore furnishing a casing 20 to receive a separating cylinder and horizontal bores 22 in ;,0 depending portions 23 of the arms, the latter bores having rotating within them 9, nail-roll common to all. The cylinders and roll will later be described in detail. Pivoted at 24 upon the trough 12 is a coverportion 26 for the nail-receptacle, this being extended forwardly at 28 to furni,sh covers for the projecting ends of the raceways. A springplunger 27, yieldable upon the cover and entering either of two depressions in a lug 29 pro- @io jecting from the trough-portion, retains said cover in e er s op or c osed posi ion. Rotatable in standards 0, 30 at the ends of the nail-receptacle is a shaft 32 having secured to it pairs of circwar plates 34, 34 situated at opposite sides of the inner ends of the raceways, the peripheries of these plates moving in close proxiniity to the interior of the trough and cover. e outer es o e en e ser es furnish closures for the ends of thereceptacle. At the opposite faces of the plates, within the receptacle, are secured buckets 36, inclined in the usual manner to lift the nails from masses contained in the compartments between the plates and drop them on upwardly diverging retaining walls 38, secured to the opposite sides of the raceway-bars 16. The sets of buckets on the plates may be staggered with respect to each other, to reduce the weight of the nails lifted simultaneously and therefore the load upon the driving mechanism. 1,0 Each compartment between the plates 34 may contain nails differing in character from those in the companion compartments, or the division of the receptacle may be utilized to reduce the mass which would be held together in a continu- f) 5 ous receptacle. Vvhen the nails are to be changed, they may be removed through doors 39 pivoted at the bottorn of the trough 12 and individual to the respective compartments. The driving of the plates and buckets may be effected 11 o by a, gear 40 fast upon a horizontal shaft 42, which is driven from a main vertical shaft 46 and a vertical countershaft 45, through spurgearing 47 and worm-gearing 49. The gear 40 meshes with a large gear 48 secured to the shaft 75

32, the movement being in the direction of the arrow in Mg. 1. The gear 48 also meshes with a pinion 50, upon a shaft 52 journaled upon the cover 26 and having a second pinion 55 meshing with a pinion 54 upon a shaft 56 also rotatable upon the cover. On the shaft 56, which extends the full width of the cover, is a series of toothed clearing disks 58, one of which is furnished by the pini-on 54. These disks turn in close prox10 imity to the upper surfaces of the raceways and act to sweep back into the receptacle crossed nails which tend to. interfere with the advance of the nails properly hanging by thei.- heads upon the bars I 6. 15 Referring particularly to Mgs. 3, 4, 5 and 10, I have arranged to turn in the casings 20, cylinders 60, one for each raceway-slot. The cylinders are protected, with capacity for ready access to, them, by individual covers 62 pivoted at 64 bn the cover20 portions 28 and having finger-pieces 66 by which they may be thrown back. On the periphery of each cylinder are gear-teeth 68, with which meshes a rack-block 70 guided in depressions in the ends of the arms 18. Through the entire 25 series of blocks passes a spindle 72, in which are recesses, each containing a compressi6l-i-spring 74. One extremity of this spring abuts against the end-wall of its recess, while the other cbntacts with a projection 76 from the corresponding 30 rack-block 70. Thus, when the spi-ndle is moved to the right, as viewed in Fig. 3, the rack-block-s yieldably turn the cylinders 60 in their casings. As best shown in Mg. 4, each cylinder 60 has a slot 80 formed between a vertical wall 81 of a 35 recess in the side of the cylinder, this @,,Tall being curved inwardly and rearwardly, as said cylinder is rotated for delivery, and an outer wall provided by a spring separating finger 82 secured to the cylinder at 84. Normally, an opening at 86, 40 between the end of the spring-wall 82 and the cylinder-wall 81, is alined with its raceway-slot. , As the nails descend each raceway-slot in a seri-es, that leading is received by this space 86, and as the cyhnder turns, the forward edge 90 (Fig. 5) 45 of the spring-wall separates the nail from those succeeding it in the raceway. As the rotation continues, it brings an eniarged end 9 2 of the slot 80 against the nail aild transfers it to an opening 94 through the bottom of the casing 20. 5( The diameter of both the vertical openings 9? and 94 is such as to pass the head of the nail. The yieldability of the wall 82 guards against breakage if the edge 90 does - aot strike accurately between nails, the wall being defleclu-ed somewhat .5.5 as pressure is applied by it. That outward deflection may not be interfered with, the ends of the raceway-bars are relieved or coneaved at 93. The edge 90 of the wall 82 is curved downwardly and rearwardly. If the shank of the hanging 60 nail happens to be displaced inwardly from the vertical, this edge will have a gradual straightening effect, drawing the entire nail into the slot 80 as it removes it from the raceway. To guard against the terminal nail being jarred rearwardly 65 along the slot 80, so two nails might be received by the cylinder at the same tiine, a projection 95 fror-q the raceway-bar at the side from which the spring-wall approaches, extends into a circumferential slot 97 in said wall and in the cylinder. 70 Tbis positively prevents such displacement. In the bores 22 in the arm-portions 23 of the basecasting, a nail-holding and nail-ip-v6rting roU 96 turns. Through this roll is a passage 98 for each of the cylinders 60. Each passage passes 75 ihrough the roll and in its rotation may be alined with the casing-opening 94 in a receiving position; with a casing-passage @99 leading to one of a set of nail-tubes I 00 @(Fqg. 7) in a delivering position; and horizontally in registration with one of a set of testing passages 102 in the casing 5 (Figs. 6 and 8). As the nail-roll.is driven, in a manner to be described, a cam 104 (Mgs. 2 and 3) upon its end engages a,.projection 106 on the spindle 72, reciprocating this and causing the bscillation of the cylinders 60. The movements 10 of the roll and cylinders are so, synchronized by this connection thalt as the nails are pick,.@d from, the raceways by the spring-walls 82 and @,re dropped through the openings 94, they will be received by the roll-passages 98, which at that 15 time register with said openings. To rotate the nail-roll 96, a lever 108 (Figs. 1 and 6) is fulerumed beneath the trough 12 to turn about a horizontal spindle II 0. This lever has two arms I 1 2 and I I S. The arm I 1 2 carries at 20 its forwa-rd extremity a gear-segment 9 '4 nieshing with a pinion II 6 fast upon. the roU. A rod I I 3 joins this ar-.,n to a bell-crank-lever 12 0 which o.Qcillated by a cam 122. During the operation of the apparatus, the periphery of the cam w,'@ll engage a roll 123 upon the lever, but, initially the roll is separated from the cam by me.ans @;hich will later be di-,scribed. The operation of this caw- may be as in the loader-controlling mecha.-iism bf l@etters Patent of the United States No. 30 11785,928, Benjamin, December 23, 1930, except that it is formed to serve the purposes of the p . resent, organization. A spring 124 holds the rod II 8 norr-rially down, to be elevated by the cam when a hand-lever 126, fulcrumed at 128 upon a .35 bracket projec'uing from the frame of the heeler IF, -A's actuated by the operator against the force of a spring i29 (Fig. 3). The co,-Tltour of the cam is such t I hat the nail-roll may be turned from an initial testing position (Flig. 6), with its passages @o 98 in alinement with the casingpassages 102, to a delivering or advancing position in registration with the tubes fOO (Fig. 7), then reversely into receiving relat-lon beneath the openings 94, and finally with a contained load of nails back into 45 P,,Iinement with the testing passages 102. Secured upon the end of the nail-roll is a feeler-controlling d@'@sk 130 (Figs@ 2, 3 and 6 to 8), which has in its periphery a depression 132 to receive a roll 134 upon a lever 136 fulcrumed upon the,forward r)o extremity 6f an outer trou.-h-extension 14. At the opposite or inn,.,r extremity of the lever is a gearsegment 138, vih;ch Pcts on a pinion 140 fast u-,oon a horizontal, shaft 142 journaled beneath the trough-extensions. At one end of the 55 shafl@ is a collar 144, and thi., collar is joined to the adjacent trou,-h-extension by a torsion-spring 1,1,6. The eifect of this spring is to urge the shaft in a cleekwise direction, as viewed from the right of the appardtus, and I.hrough the gearing 138, 60 148 force the roll 134 against the periphery of the disk 130 and thus caus@e said roll to enter the depressioii 132 @vhen the latter registers with it. For each of the passages 98 iii the nail-roll there ;s a pinion 148 on the shaft 142, this being con- 65 nected to the shaft yieldably by a torsion-spring 150 (Fig. 10) joined to the pini6n and to a. collar 15?' secured to the shaft. The rotation of the pinio-Li upen the shaft under the inLiLience of the sprlrg -is limited by a slot in a collar 151 fast on 70 the shaft, into which slot extends a projection 1.93 fror,.i the pinion. Each pinion meshes with a heirizon'@ ai'ly movable rack 159 upon a feeler-rod 156 mbunted to reciprocate in the corresponding passage i 02 (Pig. 6). Consequeiitly, when the 75

4 2,181,139 roll 134 enters the depression 132, the feeler 156 is yieldably projected into the ahned nailrollpassage 98 to test for the presence or absence of a nail. In so doing, it determines the position of a stop 160, which is movable by the corresponding pinion 148 in mesh with a rack 162 upon the stop. Each stop is guided by a stud 163 projecting from one of the arms 14 of the drum-casting for inclined downward and rearward movement beio tween the corresponding collars 151 and 152, as may be seen in Figs. I and 10. Projecting from the hub of the lever 108 is a lug 164 arranged for contact with a lug 166 upon the hub of a lever 168 (Flgs. 6 and 7). Because of this relation, the levers IO 8 and 168 may either be turned separately or together. The lever 168 may be considered as a compound structure formed by projections from the spindle II 0. Irl addition to the lug I 66, there is a series of pro@,k@ jections 170, one for each of the stops 160, and two arms 172 and 173 provided with respective gear-segments 174 and 175. The segment 174 meshes with a pinion 176 fixed upon a shaft 177 journaled transverseiy of the base 10. Also fast upon the shaft 177 is a pinion 179 engaged by a rack 17 3, r-qc@vable horizontally by a link I 80 connected to an arm 182 mounted to turn about a spindle 184. Also turning about the spindle is an arm 166, which is joined to a rod 188 connected to the treadle of the heeler F. When the rod is raised, as a consequence of the depression of the treadie and prior to the tripping of the heelerclutch, a face 187 upon the arm 186 presses against a face 189 of the arm 182. This moves the rack 178 to the left (ng. 6). The segment 175 of the lever-arm 173 meshes with a pinion 191 rotatable about a portion of the nail-roll 96 and has turning with it a disk 192 in close proximity to the disk 130 (Figs. 3 and 6). As best illustrated in Fig. 7, this disk 192 is provided at its periphery with a camwall 194 leading to a terminal-portion 195 which corresponds in depth to the depression 132. When the depressions 132 and 195 are in registration, it gives an opportunity for the roll 134 to enter them, so the lever 136 will be moved by the spring 146. This, through the gearing 138, 140, 148 and 154, -,vill produce the testing action of the feelers 156. If these feelers, as they are moved into the passages 98 in the nail-roll 96, find all of these supplied with nails, such feeler-movement is arrested, as appears in Fig. 6, and the stops 160 are retained by their racks 162 above the ends of the projections 170 from the spindle II 0, which projections form a portion of the lever 168. Therefore, said lever may be turned upon elevation of the treadle-rod 188, as already described. During rotation of the shaft 177 caused by this inovement oj' the treadle-rod, it is turning a cam 200, which is fast upon it, carrying a eircumferentially extended surface 203 upon said cam along a roll 202 upon the depending arm f 13 of the lever 108. The contour of the cam 122 is such that at the beginning of a cycle, the spring 124 tends to cause the lever 108 to remove the nailroll from the testing position which it should occupy. Thecam2OC,however,byengagementwith the roll 202, initially retains the lever 108 against movement and the roll 123 spaced from the cam 1-0 122 (Flg. 6), with elements in the testing relation in spite of the influence of the spring. The pinion 179, in addition to rotatiiia. the cam 200 to produce the effect just stated, under the influence of the rack 178, is operated to shift the 75 rack in the opposite direction. This is effected from the cam 12 2, by @ way of the lever 12 01 the rod 118, lever 108 and its projection 164, the projection 166 of lever i68, gearing 174, 176 and shaft 177. The arm-surface 189, from which the surface 187 became separated upon the retrac- 5 tion of the treadle-rod 188, is thus restored to its active positioii, the lost motion between the two surfaces being taken up. This movement occurs from the point at which the rack was left after the previous treadle-depression. 10 Considering now a complete operating cycle of this nail-supplying apparatus, there is at the termination of the preceding cycle a load of nails resting upon the drivers in the jack.of the heeling machine F being supplied, ready for inserlr) t;ion, and there is another load in the passages 98 of the roU 96, their heads lying toward the rear. The loader-block L of the heeler is beneath the foot-plate P at which the nail-tubes 100 terminate, the loader-block-shutter 1 being closed. 20 The roll 96 is i-n the testing position, as appears in Fig. 6, the depression@ 132 of the roll-disk 130 and the depression 195 of tlae disk 192 are in registration, receiving the roll 134 of the lever 136; ind the feelers 156 are within the roll-passages. 25 The plates 34 in the nail-receptacle 12, 26 are in continual rotation, their buckets 36 supplying nails N con,@tantly to the raceway-slots, these nails hanging by their heads upon the bars 16 in unbroken series. Each series is held against @30 advance by the wall 81 of the slot 80 in the corresponding separating cylinder 60. The operator places a shoe upon the jack of the heeler, applies a heel to the heel-seat and depresses the treadle of the m,achine. As in Letters Patent of the .35 United States No. 1,855,405, MacKenzie, April 26, 1932, this brings dow-n the pressure-abutments upon the heel to clamp the work upon the'jack. The final effect of this treadle-action is to trip the heeler-clutch, so the drivers rise in the jack 4i) arid force the nails which they carry through the heel-seat-material into the heel. There is, however, an interval during which the rod 188, elevated by the treadle at this time, may act upoii the distributor to cause the delivery to the .4. waiting loaderblock of the naiis contained in the roll-pas@ages 98. First, however, the feelers 156 must be withdrawn to release the roll for its dumping movement. The rising treadle-rod forces the arm-surface 187 against the opposed surface 189 of the arm 182. This shifts the rack 178 to the left (Fig. 6), rotating the shaft 177 and turning the le-krer I 68 anticlockwise to lower its segmei-it i75. By this segm,ent, the disk 192 is rotated clockwise to the position shown in Fig. 7, its depression 195 leaving the depr ession 132 of the disk 130, with which it is initially alined, and its cam-surface 194 forcing the roll 134 of lever 136 out of the depression 132. The lever 136, acting tl-irough the intermediate gearing, 60 withdraws the feelers from the passages 98, leaving the roll free. This is on the assumptio.n that the load of nails in the roll-passages was complete, and that the feelers have located the stops 160 above the ends of the projections 170 of the r)5 lever 168, so the upward movement of the treadlerod would not be interfered with. Had one or more of the feelers fully entered the passages 98, as appears in Fig. 8, the corresponding stops 160 would have b.een in the path of their projec- -70 tions 170, and the operator would have found the treadle locked against movement. Because of this, movem.ent of the feeler-controlling disk 192 would be impossible, and the nail-roll would also be locked by the feelers. Looking at the@75

:nii5efianfsni, he wouid observe trciin the po@itibns of the stops which of the nailroll-pbssages *6re empty. Horizontally alined with each te@tiiig passage 102 in the casing surrounding t-he nailroll is a passage 212, formed in a forward pro" iection 213 from a frame-arm-portion, 23. In ii@s passage a loading @.,od 214 is guidi@d. The rod is held nbrmally against outward movemlent by a latch 216 pivoted on a collar 217 at the outer 10 extremity of the rod, but inay be released gnd retracted manually, freeing a slot 218 in the top of the ptojection 213 and opening irito the lia@sage 212. The slot is of the pro]@br iotni to re@ ceive a nail with its head at the inner side. A 15. nail having been introduced through the slot into each em-pty passagei the cortesponding tod or rods 214 are forced in and '-,t@tc'bed. This carties the nail into the nz@il-roll-passage, the 6nd Gf the rod furnishing a closure for the apeiing in 20 the casing through which the introduction was made. A guard-bar 219, projecting from the collar 2i7 into the slot, maintkins said slot nar@ mally closed and holds the collar and - latch against rotation about the axis of the rod. The inissing nails '@hus being supplied, the stop8 160 will all be retracted. This unlocks the treadletod 188i whic--q may b@ elevated in the bcttiation of the heeler F. The unlocking of the nail-roll l,y the wi-thdrawal of the feelers results, prepar-, 30 ing for the delivery of the I load of nails from the roll. During the withdrawal of the f,@elers following .tl,,e successful depression of the treadlo, the Surface 203 of the cam 200 has been traveling along 35 fhc- roll 2L'2 i-n a clockwise direction (Fig. 6) urider the influence of the rack 178, the lever 168 be-.ng tiirned ant,'@Clockwise .tnd the pbsiti6n cif the lever I 0 8 remaining unchanged. The lug 1 rjr6, 4 the movement of the lever 168, has arrived in @n 40 proximity to the lug 164 of the.resting lever 108. Now, as the rack 178 approaches the eiid of the movement produced by the treadle-r'od 188, the sur@lace 293 of. the cam. 200 passes from and fr6es the roll 202 of lever 108. The spring 124 acts upon. the '@ever 108, this bei-ng per 'mitted bS, the 45 i-qitial spacing of the bell-craiik-rol-I 123 from the 188 C91m, @ 22, and the lever with@ the compan-ion lever 168 under the influence of the rack, assumetheposi-tibnsappea-ringinFig.7. The,lever I 0 9, through i-ts segillent I I&, rotates- the nail,50 1-oll clockwise to aline the passages 98 with the c asing-p,assages 99, so the loa@d of nails peisses, heads dbv,-.i, irto the tubes 100 and falls th6rethrough u-pon the shutter I of the loader-block U,5 L; The coiatrbl of the distributor by the trebd-le of the heeling machine is thus corhljl6ted fot the cycle, and the final treadle-depreszion caiA8es the opera@tion, of the nailing mechanism to attach the heel to. th-,, jacked shoe by the previbusly deliv(;o ered load c-'e nails.
