4 cause the magnet II 3, to rotate the ratchet wlaeel I 18 and rotate the shaft 119 oneeighth of a revolution. This will cause the cam or disk 123 to move away frori switch 126 so that this switch will automatically open @and thereby deprive motor 62 of current. IIowever, before motor 82 has been deprived of current it has m6ved the carrier 12 on.- @fourteenth of its travel so that a ne@v -rug 1,-older will come opposite the end of the platform. At the same time that switch 126 is opei-ied, oiie of the cams of disks 122 will close switch 136, whereupon current will pass from the supply t 0 2, through wire 10 31 Nvire 13 7, switch 136, wire 138, wire 139, wire 140, to the inotor 58 and thro-agh this motor to wire 141, wire 132, wire I qjO, back to @the source of power. This will set rqotor riS into motion for moving the power chain 54 and associated parts back to their former positions. This rnovenient continues 20@ until the traveling nut 73 strikes the projection 91 sG as to push pin 93 and close the switch 95. When this switch is closed, current will pass from the source at 102, through wire 103, wire 137; switch 136, wire 133, wire 139, wire 142, switch 25- 95 I wire I 1 2,, magnet I I 3, wire I 1 4, wire I 08 and v7ire 109, bacl,: to the source. By the closing of the switch 95@ the circuit of magnet 113 will be closed and the ralchet wheel 118 will be rotated one-eighth of a revolution. This vriII cause the so@ calli or disk @22 to move away from the switch 136 and, at the same time, cause the cam or disk 121 to close the switch 143. When this has belln done, current will pass from the source at 132, 1 through w,re 103, wire 144, switch 143 wire 35@ 145, wi-re 146, wire 149, through switch 99, mot6r @ 83, wire I @50, wire 108, and wire 109 back to the sou,.ce. Current flowing through motor 83 operates the sinle sufficiently to move one rug holder 93' on carrier 13 one step forward and then the 40i@ currc-nt is turned off by the action of the rqagnet 113 rotaoing wheel 118 so that the disk 12D will be in the position shown in Fig..2. This result is secured by the fact that current flowing'in wire @4;r3 will divide at hand switch 98 and some 45," of the current will flow through wire 981, switch ltl7, wire 148, vdre 135, magnet li3, wire 114, wire 108 and wire 108 back to the source. Curi.-ent flowing in this circuit will cause magri-et I 13 t6 rotate shaft II 8 and move the cam on disk 50, 121 away from switch 143 for opening the circuit of motgi, 0,3. A-t the saine time the cam on disk 12,3 will close swil@-ch 104. The parts are so tiialed tb-,tt the cam 159" of disk 150' acts to close swil.ch @,47 iirmediately at the end of the tiinc for r-notor 83 to function so that the rug holder will stop at the proper point opposite platfoi:rri 2. The cycle then repeats. Each time the n,,)tor 82 functions the indicating arm 151 on dial 9 --iove@@ one@fourteenth of a revoluti6n so as to point at one of the legends 652 for indicating when each particular rug is opposite the end of the platform 2. The same is true in regard to the n@iotor 83 as each time it functions the pointer 150 will move one-fourteenth of a revolution to 05, point at one of the legends 154 on dial 8. As sli.own in Fig. 6, the poi,.nter 151 is pointing at the numeral 2 which would be the beginning of the cycle. At the same time, the cam 159" on the@ disk 15F." is closing the switch 147. The disk 150 70. is geared to the shaft 15, as shown in Fig. 7, and makes one revo)Lition 'Lor each forward movement of each of the rug holders on the carrier. As shown in Fig. 7, the gear wheel 156 is rigidly secured to the shaft 15 and also a pinion 157. Gear wheel 156 meshes with a pinion 158 to which the disk 150 is secured through a suitable shaft 159'. The pointer 159 is rigidly secured to disk 150 and rotates therewith. Pinion 157 continually meshes with a gear wheel 160 which is of the same size as gear wheel 156. gear wheel 160 is rigidly secured to a shaft 161 which in tum is rigidly secured to pointer 15 1. The gearing is so proporti6ned that the disk 150 and pointer 159 will make one complete revolution for each one-fourteentli of a revolution of the pointer 15f. When the parts are in normal functioning position and all the manually actuated switches shovrn in Fig. 2 are closed, the mechanism described will continually function as long as its Is power is turned on. A& the parts function, one rug is displaced from carrier 12 and then retumed to carrier I 2 and then 9, rug from carrier 13 is displayed. 'I'his is foll6wed by displaying, a rug from carrier 12 and then from carrier 13. 20,' This action is continued until all the rugs have been displayed. After the twenty-eight rligs have been displayeo, if the power is left on, the apparatus will repeat the operation and will reI-jow- 25@ display the rugs@ in the order mentioned. ever, if some particular rug should be attractive to the customer and he should desire to have the rug displayed again, the parts of the apparatus may be adjusted to cause that one special rug to be re-displayed and left displaced for any de- 30, sired time. For instance, if the rug indicated by the numeral 4 in Fig. 2 were desired, t-he switches 98, 99 and 100 could be opened and switches I I and IO 1 closed. At this time the switch 126 wowd also be closed so that current 35, would pass from point iD2 t-Tirough switch 126, wire 129, wire 130, switch IO 1, motor 82 wire 13 i wiz-e 132, and wire 109 back to the source. This would cause motor 82 to continuously function and thereby cause the carrier 12 to move con- do, tinuously. When the pointer 151 reached the numeral 4 in Fig. 2, switch 101 would be opened ard the@ remaining switches closed, whereupon motor 57 would function to pull the rug from the carrier 12@ When this had been done, the switch 46, 1 1 would be opened. 'Mis would stop the apparatus with the desired rug exposed on platform 2. This 1-ag would remain exposed until the apparatus was again started. If any of the other rugs were desired, a similar operation could 501. be made toi bring the desired rug to a point opposite the platform and then the carrier stopped after which the pulling mechanism could be started and actuated until the desired rug was pulled into view. Under circumstances of this kind the main switch would be@ opened so as to stop all moving parts until the customer had ample time to examine the rug. I claim, 1.

Patented Jan. 23, 1940 29188@185 UNITED STATES@PATENT OFFICE 2,188,185 RUG DIISPLAY APPAP.ATUS Job Hutchinson, Great Neck, N. Y. Application October 14,1939, Serial No. 299,488 16 Claims. This invention relates to display devices and particularly to an improved display apparatus for displaying rugs or similar articles, an object being to provide-a construction which is compar.5 atively simple and wherein the rugs are automatically brought to view from time to time as the apparatus functions. Another object of the invention is to provide a rug display apparatus formed with a central 10 platform and end compartments, together with means for moving rugs from the end compartments on to the platform for display. A further object is to provide a device for successively displaying rugs from a plurality of com15 partments provided with means for quiekly bringing any desired rug to view for a second inspection. An additional' and more specific object of the invention is to provide a rug display apparatus 20, for displaying rugs on a platform adjacent the rug storage compartments, with the mechanism so formed that the rugs may be displayed successively as the machine continues to function or may function to bring a single xug to view and 25. leave the same exposed for any desired length of time. In the accoinpanying drawingsFig. 1 is a, front perspective view of a rug display apparatus disel6sing an embodiment of the So I invention, a rug being illustrated -on the display platform; Mg. 2 is a diagram of the electric circuit used in the mechanism of the apparatus shown in mg. 1; 35, Fig. 3 is a horizontal sectional view through the apparatus shown in Fig. 1, the section being taken on the Me 3-3 of Mg. 4; Fqg. 4 is a vertical sectional view through Mg. 3 on the line 4-4; 40 Fig. 5 is a perspective view illustrating how the rugs to be displayed are temporarily conneeted to supporting canvas sheets; Fig, 6 is an enlarged side view of the upper part of one of the compartments shown in Fig. 1, 45 certain parts being broken away and other parts being sho,,@rn in dotted lines to illustrate the general arrolngement of the moving chain and associated parts; Fig. 7 is a sectional view through Fig. 6 ap5O.Proximately on the line 7-71, Fig. 8 is a plan vew of a chain driving mechanism embodying certain features of the invention, the top plate being removed; Fig. 9 is a side view of the structure shown in St, -F-ig. 8; (Cl. 40-84) @ Fig. 10 is an enlarged fragmentary sectional vi ew thr6ugh Fig. 9 on the line 10-10; Mg. 11 is a fragmentary top plan view of one e nd of a @rug carrying roller and one end of the rug folding chain; 5 @ Mg. 12 is a longitudinal vertical sectional view thro ugh one of the rug carrying rollers shown in Fig. 4, the section being taken approximately on the line 12- 1'2 of Mg. 15; Mg@ 13 is an enlarged fragmentary sectional 10 vie w through Mg. 2 approximately on the line 1 3-13.

A front wall 6 is also provided so as to cover the mechanism below the platform-. 5 The casing I is also provided with a bottom 7, as 3 sho wn in Fig. 4, so that all the moving parts of the mechanism are either behind wall or in com partments 3 and 4, except the indicating me mbers or dials 8 and 9 shown in Fig. 1. As 40, illust rated in Fig. 1, there is a rug ID exposed to vie w and this rug extends from near compartmen t 3 to near compartment 4. Smaller rugs than rug I 0 could be displayed but larger rugs could not be displayed in the particular appa- 4r, ratus illustrated. The rug I 0 may be a full-room size rug or, in fact, a rug of any desired size. It will be observed that the apparatus is only slightly longer thari the rug and, consequently, the entire apparatus will not take up much floor space 50 in a salesroom even though a large number of rugs are in the apparatus. As indicated by the dials 8 and 9 there are twenty-eight rugs in the apparatus,, there being fourteen rugs in each compartment when the rug I 0 shown in Flg. I 65

2 is in its stored position. The apparatus is adapted to be operated by a swtable power means and for convenience in actuation electrically actuated devices are used. 5 When it 4s desired to start the apparatus, the master switch I I is closed and immediately the apparatus begins to operate. If a rug is in the position shown in Flg. 11 it will in a very short time move into one of the compartments 3 or 10 4, and, at the same time, a new rug will take its place and: remain on platform 2 for a certain length of time and then a third rug will be brought out as the second rug is retracted or moved into a compartment. The construction 15 is such that the rugs are alternately moved out of one compartment and into the other compartment until all the twenty-eight rugs have been displayed. If the master switch I I is kept closed the apparatus will continue to function 20 a,nd display all the rugs a second time. This action will be continued until the master switch has been opened or certain other switches 6pened as bereinafter fully described. Referring more partiewarly to Figs. 3; and 4, 25 it will be seen that in the respective compartments there are provided rug carriers 12 and 13 which are identical in construction and therefore, the description 6f one will apply to botb@ The carrier 12 is provided with a pair of top 30 sprock,-t wheels 14 connected by a shaft 15 and a pair of bottom sprocket wheels 16 connected by a shaft 17. On these sprocket wheels are mounted the respective chains 18 and 19. Each of these chains is formed as an ordinary sprocket 35 chain except that at spaced intervals there is provided a, special link 20 shown particularly in Figs. 6 and 14. Each of the links 20 is formed with a bifurcated end 21 accommodating the flattened end 23 of a bolt 22 which extends 40@ through a rug support 12'. As shown particularly in Fig. 12, shaft 24 is connected at its ends through the flattened ends 23 to the respective chains 18 and 19 and is therefore fixed or held ,.gainst individuol rotation. Drums 25 and 26 45 are rigidly secured to shaft 24 in any suitable way, as, for instance, by set screws 27. Each of ,these drums is provided with a hook-shaped abutment 28 having a reduced end 29 (Fig. 14) fitting into a suitable bore in an, enlargement 50@ 30 6f the drum. A bolt 31 extends through the enlargement 30 and also thr6ugh the extension 29, firmly locking the abutment 28 in place. The b@lock 32, as shovm in Fig@ 12@ is rigidly secured to shaft 24 and one end of the coil spring 33 is 55 connected @vith said block while the opposite end is connected with the shaft 24. Suitable journal or bearing inembers 34 and 35 are carried by shaft 24 and on these bearing members is mounted a tubular member 36 which with the remain60: ing members form a rug holder or support 12'. A sheet of canvas or other textile fabric 37 is seei-ired at one end to the tubular member 36 and at the other end is provided with a hern 38 accornr@,lodatiiig a pull bar 39 The pull bar 39 65: .9,t its respective ends normally rests on respective abutments 28 carried by the respective drums 25 and 26. As shown in Mg, 4, there are fourteen of the rug liolders 12' and on each holder a sheet of canvas 3T is mounted as described. 70 I-,i Mg. 5 thi@@ sheet of fabric is shown stretched out and carryiiig a rug 10'. Suitable fastening means, as for instance pin hooks 40, connect one end of the rug to a flap or extra piece 41 stitched to the sheet 37. At the opposite end the hook 75' pins 42 are looped through an @elastic cord @ 43 which is carried by the fabric 27. In this way a rug may be readily mounted on the canvas 37 and readily removed therefrom. When mounting a rug on the sheet 37, the sheet is unwound and the rug mounted in place as shown in Fig. 5 5. The parts are then released and spring 33 will automatically wind the sheet of fabric 37 together with the rug so that the parts will appear as shown n Figs. 12 and 3. Mechanism as hereinafter fully described is adapted to en- 1( gage the ends of the respective pull bars 39 and pull the sheet of fabric 37 together with the rug niounted thereon untii the rug is exposed to view as shown in Fig. 1. The carrier 12 has been described in detail but it will be noted that carrier 15 IS is cf identical construction and the rug holders 12' mounted on the carrier are of the same construction. When the machine is in operation the rug is oulled from a rug holder 12' while the carrier 20 1,2 is stationary and is left exposed on platform 2 for a certain length of time. The rug just mentioned is then retracted on to the holder 12' of carrier 12 and during the time of retraction a second rug is pulled from a holder 13' on car- 25 rier 13. As the second rug is retracted to holder 13' a third rug is pulled from a holder 12' on carrier 12. This action continues as long as the w-achine is op-,rating unless certain switches hereinafter fully described are manipuiated for 30'@ Producing certain sl>ecial results, namely, the displayipg of certain specific rugs rather than the rugs in succession. The plilling mechanism for pulling the rugs to the display position shown in Mg. 1, is shown 35: functioning in Mg. 13. From this figure it wili be observed that a rug 10" is being puiled to the display position whi-le a rug 10... is being retracted, As the hook 44 moves around the sprocket wheel 45, it will deposit the pull bar 39 40@@ on the e@butment 28 connected to the rug holder 13'. After the bar 39 has been deposited on the abutment 28, the hook 44 moves downwardly a short distance around the sprocket wheel 45 and approximately at the same time the rug h6lder t5: 13', shown in Fig. 13, is moved upwardly onefourteenth of the travel of the respective chains 12 ar@d 19, whereby this rug holder, rug and associated parts -will be out of the way and a new rug holder 13' and associated parts will be posi- 50! tioned as shown in Fig. 13 ready for the hooks 44 to engage the pull bar thereof and pull the rug and associated parts from the roller in an opposite direction to the arrow 46. V,7hile this is taking place, the respective hooks 47 and the 5r,: rug I 0 " are moving to the right as shown in Fig. 13. As shown in Mgs. 3 and 4 there are two sprocket wheels 45 connected by a shaft 48, which shaft is mounted in suitable bearings 49 and 50. At the opposite end of the platform 2, 60,1 similar sprocket wheels 45' are provided and cbnnected by a shaft 51. The shafts 48 and 51 also carry driving sprocket wheels 52 and 53 over wbich a, sprocket chain 54 fits. Sprocket chain 54 is the power chain and is adapted to 65 rotate the respective sprocket wheels 45 and 45, to move the respective pul-I chains 55 and 56 (Fig. 3) a certain distance in one direction, namoly, a distance a little greater than the length of the platform 2 and then the same distance 70 in a reverse direction. In order -for the power chain 54 to be actuated, a special mechanism has been provided, as shown in Figs. 4, 8 and 9. This rnechanism includes a pair of electric motors 57 and 58 secured to a y6@.

diive shaft 59. A worm 60 is rigidly secured tb the drive shaft 59 and continually meshes with a worm wheel 61 which is rigidly secured to a shaft 62. Shaft 62 is provided with a worm 63 cont i inually in mesh with a worm wheel 64@ which latter wheel is rigidly socilred to a shaft 65 carried in swtable bearings in the frame 66 - A &iving sprocket wheel 67 is rigidly secured to shait 65 and therefore rotates therewith. The power 10 cllain 54 rests on top of the sprocket wheel 67 and passes beneath the idler sprockets 69 and 70, the sprocket 70 being loosely mounted on the shaft 59, while sprocket Nvheel 67 is rigidly secured to a shaft 71 carrying a threaded sleeve fd 72 bn ,NThich a traveling nut 13 is mounted to move back and forth as the sleeve is actuated. This'nut is provided with a notch 74 for accom-' modating the fixed rod 75 whereby the nut cannot rotate but may move back and fortl-i. Shaft 20, 71 is rotatably rnounted on a swinging frame TG which carries the shaft 7i and rod 75 and associated parts. TWs frame is provided with a pair of offset members 77 @Lecommodating set screws 78, as shown particularly in Flg. 9. These 25 s6t sorews press against the end plate 79 of the frame 66. By adjusting these screws the idler 6T may 1,,e shifted to take up any slack in the power chain 54. Motor 57 rotates in one diree-, tion when energized and motor 58 rotates in the 30 opposite direction. Shaft 59 is connected to the armatures of both these mo;tors and, consequently, current is turned off one motor before it is turned on the other motor. The armature of 6ne motor will rotate freely as the armature 85' of the other motor is driven. By reason of this structure; it will be seen that when one of the mo@ors is functioning the respective hooks 44 are moving to the right, as shown in Figs. 3 and 13, anc-I vrhen the other m6tor is fun6tioning the 40 hooks 47 are @noving to the left. The hooks 44 when moved to th& left stop at the dotted position shown in Fig. 13 while the hooks 44 move to@a similar position at the opposite end of the travel of the chains when they reach the end 4,6@@ of 'their travel. The respective pairs of hooks 44 and 47 extend through the respective slots 80 and 8 I (Fig. 3) which extend longitudinally for the f@il length of the platform 2@ The chains are adapted to move beneath tlie pl?,tfbrm while the go@. hook-s extend through the sl6ts to a certain distance @Lbove the platform. The motors 57 and 58 actuate the chains 54 al'id 55 while motors 82@ and 83 actuate the sprocket vrheels 84 and 85 and through these sprocket wheels the respective r,5 chains 86 and 87, which chains fit over and actuate the sprocket wheels 88 and 89 secured to the respecti-,re shafts 17 and 171, which shafts are also rigidly secured to the spr6eket w@eels 14 and 16 carrying the respective chains 8 and 9 60 of the carriers 12 and 13. The motors 82 and 63 operate in proper time with the motors 57 and 58 so as to alternately bring the successive rug holders opposite the end of the platform so that the rugs thereon may be engaged and pulled 65 on to the platform by the respective pairs of hobks 44 and 47. In Fig. 2 a diagram is presented which shows the wiring for the, respectiv6, motor@@ and associated parts whereby the motors are caused to 70@'function in proper time with each other to sec.ure the results above set forth. In Figs. 8 t6 10, inclusive, a switch mechanism is shown which is L,.,Iso part of the diagram shown in Mg. 2. As the chain 54 moves in one direction, nut 73 will 75@ be moved by the threaded member 72 in one 3 direction and when the chain 54 is reversed nut 73 will be reversed. When nut 73 reaches one end of its travel it will push against the pin 90 and when it reaches the end of its travel in the opposite directio-@i it will press against-the pro- 5 jection 9i of the pivotally mounted lever 92 which presses the rod 93. When rod 90 is pressed the spring 6ontacts 94 are brought together and whentrod 93 is pressed the spring contacts on switch structures 95 are brought together and 10 the circuit closed at this point. Fig. 10 shows one of these, switches in detail from which it will be seen that there is a stationary abutment 96 having A set screw 97, whereby the contacts are prevented fl.@om swingiiig beyond a certain - point 15 so that the pin 90, or the pin 93, as the case may be, may close the switch. As the nut 73 reaches one of it-s extreme movements the switches 94 and 95@ are closed and as shown in the cuagram in Fig. 2 are illustr6,ted as being connected with the 20 wiring of the motors and other associated parts. VThen it is desired to start the apparatus, the respective switches 11, 98, 99, 100 and 101 are all closed. The switcb- I I is the master switch bnd when this is closed current from a supp@y line 25- passes through the circuit. For instance, if the current passes from the plus sign 102, it may flow through wire 103, contacts 104, wire 105, wire 106 to and through the motor 57, and from motor 5T, through wire 107, wire 108 and wire 30' 109 back to the source of current through the switch II - Current flowing in tllis circuit will rotate motor 57 until the chains 55 and 56 have moved a certain distance. Also the power chain 54 has moved a certain distance and when the 35 parts have traveled this certain distance,'nut 73 (Fig. 8) will push the pin 90 and close the circuit at switch 94, whei,,eupon current will pass from wire I 06, through wire I ID. switch 94, wire 1 1 1, wire I 1 2, magnet ( i 3, wire 114, to wire 108, th rough wire 109@ back to the source througl-i switeli I 1. By energizing tlie magnet II 3, arma4 0 tu ie 155. will be pulled downwardly against the a ction of the spring 116 (Flg. 17). This will c ause pawl 117 to engage one of the teeth of the 4 6 r atchet wheel II 6 and rotate the ratchet wheel o ne-eighth of a revolution. This circuit is closed o nly temporarily and the movement of the r atchet wheel is quickly accomplished and then m agnet II 3 is deenergized whereupon spring I I 6 5 0 w ill move the parts back to the position shown in Fig. 17 for anotl-ler operation. Ratchet wheel i I 8 is rigidly secured to shaf t ( 1 9 and on this s haft there are provided four disks, namely, disks 1 20, 121, 122 and 123. Each of these disks is 5 5 provided with a pair of diametrically oppositely positioned switch closing cams 124 and 125, as shown in Mg. 18@ When the magnet 113 rotates the shaft I (9 one-eighth of a revolution as just described, the disk 120 will be moved so is to permit the sv@itch 104 to open. At the same time 60 it will move the disk 123 for 6los4@ng the switch 126 ' When switch 126 is closed, current will pass from the source of current at point 102, through wire 103, wire 127, switch 126, wire 129, 'Wire 130 : 65 hard switch 101, motor 82, wire 131, wire 132 and wire 109 back to the source. The motor 82 will rotate as lo,@ig as the switch 126 is closed. At the same time that curreiit is being supplied to motor 82, current will pass from wire 129, to': through switch I 03, switel-i 133, wire 134, wire 135, magnet I 1 3, wire I 1 4, wire I 08 ond wire I 0 9, back to I the source. This circuit is closed only temporarily as cam 159' (Fig. 6) is closed only for a brief time. Current flowing in this circuit will
