SOUBIEIZ, OF TOLE]30, OHIO, ASSIGNOR TO OWENs-rLL:ENois GL@ASS COXPAIQY, OF TOLEDO, OHIO, A CORPOPATION OF OHTO APPARATUS FOR PRODUCING HOLLOW GLI@.WWARE Applieation filed April 16, 1928. Serial No. 270, ,282. The present invention relates to improveM6 nts in apparat-Lis for producing hollow glassware. In commercial productiod of hollow glass5 ware, si-ich for example as bottles, the wate in its fin,,il shape is delivered from a forming machine and then transferred either manually or raechanically by suitable ware handling !nechanism int,o the feeding end of an anneal10 ing leer, the latter ordinarily being a co-nsiderable distance frora the machine. 'rhe ware, during'transfer from the maebine to the leer is fnore or less chilled by contact with the outside air and u-pon being placed in 15 the leer must be teheated to remove strains and stresses therefrom. This reheating consumes a considerable period Of time, as woll as fuel, and miist necessarily be followed by gradiial reduction of the temperature as tl;@ 20 ware passes through the leer to prevent formation of strains in the ware. An object of the present invention is to provide an apparatus wherein exposure of the ejected ware to th6 chilling e-ffect of the 25 atmosphere while being tra-nsferred to the leer, is materially -reduced and iii fact almost eliminated. Thus, the extent 6f reheati-ng, and conseqtiently the annealing time r ilay be greatly decreased as compared with 30 ordinary methods. Also, a material reduction in fuel consumption is effected. To this end, the.invention consists in arranging a glassware annealing leer about the peripbery of a forming machine in such,a manner that the ware is ejected directly into the'leer from the molds and is initially positioned uprilyht in the leer, said ware mo@ing down a relati@-vely short chute or trough from the machine to the leer. 40 Another object is to provide a leer of the above character embodying a feeding device by whieh the ware is uniformly spaced apart as it is deposited in the leer. A further object is to provide a novel mee-h45 anism for rem@oving ware from the delivery end of the leer in timed relation to'feeding of ware into the opposite end of the leer. it is also an object to provide a readily acljustable timing or indexing mechanism b@ tio whiirh the I"r conveyor may be advanced in a step by step fashion, degrees yary-mlr in le ngth according to the type a-nd size of 'W-'@are to be annealed. Other objects will be appatent hereinafter.

In the preferred embodiment of t-he inven- 90 tion illustrated in the accoinpanying draw-, ings, an annealiiag leer is embodied in a ware producing unit also including a continuously rotating mold ca'rriage 15 (Fig. 6) which supports an aniiular series of warib forming 95 molds 16 each mounted on a tiltable frame 17. Suitable mold opening and closin 9 mecbanism 18 of conventional or any preferrbd type is ei-nployed. This mechanism al100 ternately opens and closes the mold 16 and
[2]11859,247 operates to discharge ware at the ejection st6Ltion IIE" (Fig. 1) wheri the mold tilts to the position showri in Fig. 6. T-he drive for rotating the mold carriage 15 is of conventional form, iheluding a ring gear 19 (Fi gs. 1, 9 and 10) running in inesh with a driving pinion 20 at the upper end of a shaft 21 which may. be continuously or intermittently rotated by anv suitable means (not shown). 10 This shaft !@l extends downwardly through the stationary base meiaer 22 (Fig. 10) which is proi,ided with an annular upwardly facing trackway 23 su@porting a circular frame 24 on which -@he ware or leer conveyor Irl 42 described hereinafter is mounted. A ting geat 25 is secured to the frame 24 (Fig. 10) and runs in mesh with a mutilated indexing gear 26 at regular iniervals. The indexin(y gear 26 periodically advances the 90 leer conveyor 42 a's will be apparent hereinaffer. This indexing gear 26 (Fig. 10) is mounted on a s6etional shaft 27 and is driven through an adjustable differential drive 28 of well known construction, by a bevel gear 26 29 running in mesh with a gear 30 fixed to one end of a horizontal shaft 31 carryine a worm gear 32. This worm ge @ar 32 (Fi@,s.-IO anid 11) is continuously rotated by a worm 33 on a shaft 33a on whl'ch is mounted a bevel 30 gear 34 running in mesh with a driving bevel gear 35 which is rotated with a,nd by the aforemeiitioned drive shaft 21. Thus, with contintiotis rotation of the mold carriage 15 rotary motion is transmitted to ihe indexing 35 gear 26 to thereby. impart intermittent rotary movement to th6 supporting frame 24 f6r a leer conveyor 42, the extent of such intermittent moveri@ent being regulated by the size of the gear 26 and the number of teeth 40 thereon. This latter feature is predetermined by the diameter of the ware being produced and annealed and the nemsary SpEteing of the ware in. the leor, as will be described hereinafter. 45 The eircular frame @4 eirries an annular series of conveyor supporting arms 40 whose outer portions 41 are disposed in a horizontal pla'ne below that of their inner ends and have secured to their upper faces a eircular ware 50 conveyor 42 which miy be composed of a series of individually removable sections. The leer (Fig@. 1 and 10) includes a tunnel 43 which is of inverted U-shape in cross section and closes the ilpper side of a major 55 portion of the ware conveyor 42. This leer tunnel mav be of any preferred construction an(i, accoraing to the present disclosure, coiasists of a sheet 'metal shell 44 in which an insulating material 45 is arranged. The in60 :@er wall 46 may be formed of sheet riietal ha-v-. ing a bright reflecting surface, such. as has been 'found advantageous in leer con@truetion and operat@on. Th6 leer tunnel may be suspended from a stat-ionary floor 48 upon 65 which the machii@e operators ordinarily stand, by means. of angle iron members 47 or other hangers. While other means may be employed to apply an annealing medium to ware in the leer, I have for illustrative purposes shown 70 :@ heater usiny gas fuel, said heater comprising a manif@'ld 56 exteliding lengthwise, of t-he leer tunnel for a predetermined distance and eqtipped with branch pipes 51 es:tending transversely of the leer and having burners 75 53 extending downwardly therefrom into the leer tunnel. A fiiel mixer 54 (Fig. 4) receives gas from any suitable source through a valved gas pipe 55, while the air supply is introduced through a -,,alved pipe 56. The 80 burners 53 are spaced along a predetermined length of the leer in a. fasfiioii determined by the type of ware bein- anne I aled and the temperature - gradient required. A suction mechani m 57 (Fig. 1) may.be arrange@d at a 85 point spaced from the heatin- zone to create movement of the annealing inedium longitudinally of the leer t,unnel at the degired rate of speed. According to the present diselbsure, the 90 leer conveyor 42 (Figs. 5 and 10) supports the w- are in an annular s6ries of transverse rows, each row including four bottles. Obviously, the rows may be composed of various numbers of bottle's -or other articles. The leer 95. conveyor 42 remains statio]Rary for a period of time sufficient tb permit settiiig a transverse, row of four'bottles thereon and is then th@ gears e corre- 1.00 an the diameter next succeeding row of bottles will be spaced longitudinally from the preceding row. Mechanism operating to obtain such placing of the bottles or 105 other ware upon the ware conveyor 42 ineludes a stationary chute 60 (Figs. 6, 7 and 8) formed with a substantially horizontally disposed lower outer portion 61. The ou'ter end of this horizontally disposed portion 61 110 is formed -@vith an end wall 62, provided with a laterally extend ing guard 63 (Fil-. 7). The bottom 64 of the horizontally disposed portion 61 is downwardly inclined transversely toward an open side 65 through which the 115 ware passes to a swinging trough or chute 66. This latter trough or chute 66 is for the. greater part enclosed in a chamber 52 and is fixed to a frame 67 fulertimecl at its upper idner end to a vertical hinge pin 68 carried 120 by a'boss 69 on the lower side of the horizontal portion 61 of the trough 60. This-, frame 67 includes an arm 70 (Figs. 5 and 7) extending be@ond the hinge pin 68, connected bv a pitman 72a and crank arm 72 to a con-, 125 tiiiuously rotating shaft'71. The shaft 71 is journalled in a bearing 73 on a stationary brack6t 74 and carries a bevel geilr 75 at its iipper end runninin mesh witli a bev@l gear 76 @t one end of @'horizontal shaft 77 (Figs. 130
[3]1,859,247 5 and 6), the laitel.- being continuously driven by the sh'aft 31 (Figs. 5 and 10) throulyh a seriesofgearsandshaftsTS. Continuoiisrotation of the shaft 77 transmits rotary movem6nt to the vertical shaft 71 (Fi-as. 6 and 7) which, throiigh the pitman coiine@tion,'causes oscillation of the trough 66 transyersely of the ware conveyor 42. In transferring bottles or'the like to the 10 leer, they are first deposited in the main chiite 60 with their necks extending downwardly. Thesi3 bottles move downwardly by grivity' and upon reaching the, horizontalli &isposea trough 61, strike the end plate or -,vall 62. 15 Due to the inclination of the bottom 64, the. bottles turn substantially as sho,%-n in Fig. 8 and move down the chut'e 66 in an uprigrht position for setting upon the ware conveyor. A guard 80 (Figs' 7 and 8) fixed to the chute 20 66 prevents contact between a row of bottles be set.up and the preceding row. kllt--the delivery end of the leer, I provide a ta'keout mechanism by which the ware is removed from the conveyor 42 one row at a 25 time, and placed on suitable ware handling mechklnism 81 by which it may be transportecl to any desired point. This takeout mechanism (Figs. I and 2) comprises a-n arm 82 liavin- one end 83 shaped to engage an end 30 bottle@ of a transverse row, while the, other end of this arm is offset and connected to a piston rod 183 of an air motor 84, said motor id.cluding A differential pisto-n 85. Constant air pressure is supplied to the inner end of the 35 air motor cylinder through a pipe 86 from a hig@h pressure supply line 87, said pipe 86 including a-valve 88 by which the rate of flow may be controlled. Variable al'r pressiire is p@riodically supplied to the other end of the 40 air motor '84 through a sectional pipe 89 in which an automatic valve 90 is arranged. The autornatic valve 90 (Figs. 1, 3 and 5) a housing 91 formecl with three comprises chambers therein; communicating with eacli 45 other through valve openings 92. A valve stem 93 extending axially through said opeiiings and housing carries a pa@ir of spaced valve disks 94 adapted to close the openings 92 one at a time -whereby the intermediate 50 chamber 96 alternately communicates with the upper and lower chambers 97 and 98 respectively, the latter chamber opening to the atmosphere. The sections of the variable air pressure pipe 89 are connected to the inter55 mediate and upper charnbers 96 and 97.1 Raising of the valve stem 93 seats the lower valve disk 94 and unseats th@ upper disk, whereiipon air pressure passe,,,, through the. pipe 89 and moves the piston 85 of'ilie air motor 84 inwardly whereby the takeout arm may engage a transverse row of bottles for removalfromtheleerconveyor42. Theaiitornatic valve 90 is actuate4 in proper timed relation to movement of the ware conveyo r by a cam 99 on and rotatable with the shaft 77 (Figs. I and 5), said cam engplging a cam Poll 100 on the upper end of the, valve stem 93. The operaiion of the.machine rnay be stated as follows: Assuming that the ware forming machine 70 is of the type in which the mold carriage rotates continuously about a vertical axis (al- - though it nlay well be of th@ intermittently r6tating..type), the finisli molds 16 are brought in succession to the ware ejoeting 75 station "E" at which the molds tilt and open 6s illu-,trtted in Fig. 6 to thereby deposit finished articles of ware in the chute or trough 60 at regular intervals. The ware enters the chute 60 in an inverted position.80 and upon striking tht end wall 62 a'nd the inclined bottom 64 (Fig. 8), moves by crravity t' transv ers6ly of the trough aiid is reinverted so that it moves down tfie oscillating trough 66 in an upright osition and is set upri(rht p 85 on the ware conveyor 42 (Fif-Y 7). This @scillatin g chute or trough 6 continuously moves back and forth across the ivare con-. veyor 42 at a, rate of speed determined by the rotary speed of the.mold carriage.' With go move ment of the trough 66 across the ware conye yor 42 in one dire.ction, one complet6 row of bottles will have beeil placed in an uprigli t positi6n on the ware conveyor. Iii the interval. of .,tiiiie prec6ding initial return 95 move ment of the trough, the leer conveyor 42 is indexed to advance the row iDf artic!es just deposi ted on the conveyor, a distance beyond the feeding oint sufficient to allow uniiiterp rupted return of the troug@i to its initial ioo position. Duriiig this return moveiiient, tinother row of articles is deposited li' on the @p conveyor and. the latter is agaiii indexed. Thus,. by the iiitermittent moyement of the leer conveyor 42, the ware is slowly carried io5 through the leer tuianel wherein it is annealed iii the eustomary manner and is reinoved froiii the ware conveyor at the delivery end of the turnel by the t.akeout mechanism pre,viously described. 110 This air inotor 84 for the talkeout.meelianism ed r6lation with and oscilla7 tion ultane ously with into, the re- 115 colvin(, end of the leer, a row is moved f ro'm within the tunnel and. is removed f roin the leer co'lveyor 42 by the takeotit inechaiiisn-i. - The automatic valve 90 (Fiks. 1 and 3)'is periodic ally o'perated by the rotary cam 99 120 on the. shaft 77 which, through the pitman connecti on, oscillates said troligh 66. The position of the caiii 99 on the shaft@77 (Fi-. - 3) determines the relation betweell the operation of the air motor 84 of the takeout inech- 125 anism and movement of the feeding trough '66 which spaces the ware in transvertie rows across the ware coiiveyor 42 at the feediiig eiid of the leer. The timing gear 26 (Figs. 1 aad 12) ad- 130
[4]li859,247 vances the ware conveyor 42 in a step by step fashion, or as otherwise desired, in timed relation to oscillatioii of the trough 66, tliiere being provided a plurality of gears so proportioned and related to each other that indexino, of tlie conveyor is effected immediai-ely 7ollov@in(Y placin of a complete trans9 verse roav of bottles or other ware on the con-. veyor. The si-ze of the gear 26 and the num10 ber of teetli tliereon, vary in accordance with the size of ware to be annealed, it being obvious that ware of relatively large diameter will require a greater degree of movement of the coiiveyor 42 than will ware of small 15 diadaeter. By adjusting the d-'Llierential 28 (Fig. 10), the tinied relation I)et",een movements of Viie ware conveyor 42 and the oscillating -chute 66 may be varlecl. For example, if the con20 veyor is beinz indexed just prior to or during positionii@g of tl-ie last of a row of bottles thereon, it is necessary to retard the operating period of the indexinlgear 26. Accordin ly, the differential me-chanism 28 is oper9 25 ated to retard the tiiiie of advance of the conveyor the necessary degree. This adjustment nioves the teeth of the indexiing gear 26 backward a pi-edetermined degree and correspondin(yly retards the period of initial move30 ment of the conveyor 42. Obviously the reverse adjustment is e:ffected if the conveyor movement is too late. By combining a ware forming machine and annealing leer as herein set forth, a compact 35 Wtre producing unit is provided and the period of time required for complete formation and annealino, of ware may be materially shortened. This latter feature is to a considerable extent due to placing the feeding 40 end of the leer in pro imity to the ware ejecting station so that the ware may be quickly transfei@red to the leer and is not chillod to any great extent by the atmosphere. Consequently, the ware does not require a relative-. 45 ly long period of heating as in the usual leeir. Modifications may be resorted to within the spi,rit and scope of the appended claim. I"at I
