DISPLAY APPARATUS.

Application filed December 31, 1926. Serial No. 158,202.

The present invention relates to an iin provenient in display apparatus.

The object of the invention is to produce an apparatus for use in displaying commodities by exhibiting them in motion in a show win dow or otherwise. and to this end the invention consists in the apparatus hereinafter desei'ibed and particularly detined in the claims.

In the arcmnpanying drawings illustrating the preferrerfl form of the invei'ition. Fig. 1 is a plan view of the apparatus; Fig. 2 is a front elevation of the same; Fig. is an en larged plan similar to that shown in Fig. 1, showingr only part of the apparatus, but showing the position ot' some of the hidden parts in dotted lines; Fig. 4 is a bottoni view of the gear box: Fig. 5 is a seetion taken on the line 5 5, Fig. v3. showing the gearing in front elevation; and Fig. (i is a transverse section of the mechanism taken on the line (fi-t, Fig. 3.

The ilhistrated einhmliment of the invention described as follows: The apparatus is providerll with a table supported b v a box 1l. @n top of the table supported the earrier I'or carrying different devices desired to be exhibited. A Carrier chain 12 is supported on top of the table 10, and hold in rectangular position by the Carrier guide 13. Thisl guide is shown in section in Fig. (l. and it Y consists of a box-shaped channel having bottoni. front and rear Walls which receive and guide the carrier chain. The upper side of the box Ais slotted at 14. Carrier posts 15 projert from the chain up through the slot 14, and upon it may be carried things desired to be exhibited hy the apparatus.

The carrier guide held. in the illustrated embodiment. in a rectangular shape by means of tour carrier chain pinions '16. onerat each corner of the rect-angle in which the carrier chain is torn'ied. The carrier chain is driven hy a sprocket gear 17. The carrier guide is provided with slots at its four Corners through ivhieh the pinions project into the guide to engage the carrier chain. Similar ly, the carrier guide is provided with a slot through which the carrier driving sprocket enters to engage and drive the carrier chain. The table is provided with a series of sockets 18 in which posts may be set to carry the devices or things for exhibition. The table may also be provided With a lamp carrier 19 for illuminatingr the apparatus.

The carrier posts 15 may be of any convenient number and arrangement, and are convenient-ly extensions of the pintles of the sprocket carrier chain 12. At 2l a shoe is s iovvn carried by one of these posts 15.

1n order to support and carry various de vices on the display apparatus means are pro vided for driving different article carriers. Thus, the shaft upon whieh the carrier driving sprocket is supported may be provided, as shown in Fig. with a` rotating table A seeond rotary element may be provided at 23, which is continuously rotated. being provided with a mitre gear, which is adapted to drive a mitre gear driven apparatus Whieh may be set up on the table in proper relation to it. .At :Z4 an oscillating shaft is provided which is adapted to be rotated first in one direction, and then in the opposite direction. This is intended also to carry an article to be exhibited, or a plate upon which an article may he carried, or otherwise.

In general, the support for the carrier driving sprocket produces a continuous slow rotary motion. the rotary element 23 prineipally a take-oft' for conveying continuous rotary motion to a convenient nearby position. and the shaft ltmay be availed of for oscillating or reversed rotary motion. In addition. provision is made for driving the plate 2.9. above the carrier driving sprocket in such manner as to give it an intermittent rotary motion. One of the important features of the invention resides in the carrier guide which supports and holds the carrier in a certain position and guides it in its motion through a certain predetermined path so that an article carried bv it Will traverse a given path repeatedly. This carrier guide at all points except. at the corners and at the place where the driving sprocket enters it to engage the chain, is rectangular in cross-sec tion with a slot in the top through which a carrier post may project.

The mechanism for driving the carrier and for continuously rotating the mitre gear Q3 and intermittently rotating the shaft at 24. is described as follows: The power is applied by means of a belt running to one of the pulleys 30. mounted on the shaft- 31 of the gear box. Inside of the box the shaft 31 carries a Worm 32, which engages a Worm Wheel 33 mounted on a second shaft 34 supported in bearings in the box and projecting at each end therefrom. so that other pulleys or gears may be applied to the ends of the shaft 34 so that Continuous slow rotary movement may be imparted thereto from sueh shaft. This saaft 34 carries a worm 35 which engages a worin wheel 36 having a hub 37 secured to the hollow sha'lt 38 by means of the set screw 40. This hollow shaft provided with a hub 4:1 which carries the sprocket wheel 17 by which the carrier chain is driven. The shaft 34 also carries the worin 4:2 which engages the worin wheel 412-3, inouiited on the shaft Llil, supported in a bearing in the box and projecting out from the box, and adapted to receive a pulley or other device to be driven from the box. The worm also engages the worin wheel 4:5, to which is secured the gear elli, both being mounted on the shaft. 23 above referred to. 'lhe gear 46 enga the gear 41:7 and rotates it contiiuiously. rlhis gear L7 is secured upon the shaft 4S carried by the box. lhe shaft 48 also carries a disk l, carrying a pin 5l and a second disk 52. The pin 5l is adapted to engage with the slots 53 off the Geneva wheel 54, which is permitted to turn when the disk brings its cut away portion opposite one of the arms of the Geneva Awheel 5ft, at which time the pin 5l operates to give the Geneva wheel a step forward. rl`he Geneva wheel 54: is mounted on the shaft 55, which passes through the center of the hollow shailt 3S and extends upwardly therethrough and beyond the end of the hollow shaft 38 at the top. Here it is provided with a collar 5G' secured to it, which rests upon the upper end olE the hub L il of the sprocket Wheel 17. The upper end oi the shaft 55 carries a sleeve 57, and on the outside of the sleeve the hub 58 of the disk 22 is adapted to lit. By loosening the screw 60 which passes through the hub 5S and tightening the screw (il, as shown in Fig. (i, the sleeve 57 will be attached to the sprocket wheel hub Ll1 and the table 22 will be continuously rotated from the sprocket wheel. By loosening the screw G1, on the other hand, and tightening the screw 60, the table 22 will be secured to the intermittently rotated shalt 55, and the table 22 will thereby be given an intermittent rotation.

Ordinarily, as has been described, the sprocket wheel 17 will be given a continuous rota-ry movement and thereby the Carrier chain will be advanced continuously in the operation of the apparatus. If desired, l1ow ever, both of the screws 60 and 6l may be tightened and the screw 40 loosened, and then the sprocket wheel will be driven through the shaft 55 by an intermittent or step by step movement.

The hollow shaft 3S also carries a gear G2, the hub of which is scoured to the hollow shaft 38 by the set screw b3. This gear (l2 meshes with the gear 64C, which in turn meshes 'with the gear 65, both ot which are mounted on bearings supported by shafts or studs carried h v the box. One olf "theee gears (55 carries a pin (ib 'which engages a slot (i7 in the arm GS, which is pivoted on the stud which carries the gear Gfl. This arm (.38 also carries a segmental gear 70, which meshes with the pinion 7l mounted on the sha lt ily this means oscillating motion imparted to the lail'er shaft.

"he amiaratue which Ytoi-nis the subject oil this invention is adapted ilor use in many f lil'ii'erent ways. Thus, the carrier chain may be advanced continuously, or it may be v: iced step by step. rlfhe plate mounted ie the table n'iay he rotated cmitiuuously, or it may he rotated step by step. Also power may be taken ollil at 23 to drive other devices supported upon the table l() for continuously1 rotating them, or lpower may be taken olli from the shaft 2l for causing rotations` to he imlpirted lo a device for exhibiting articles` first in one direction, and then in the other.

Having thus described the invention, what is elaiiued is:

l. Display apparatus having, in combination, a support, a carrier guide mounted on the support consisting of a box-shaped channel having bottom, front and rear walls, a` carrier chain received, in the carrier guide, carrier chain pinions at corners olf the carrier guide 'for maintaining the latter in shape, the carrier guide being provideifl with slots at its corners through which the pinions project into it to engage the chain, and a carrier driving sprocket, the carrier gi'iide being pro vided with a slot through which said sprocket enters to engage and drive the carrier chain.

2. Display apparatus having, in cornbinatien, a carrier chain having artiele-carrying posts secured to it projecting to one side of it, a slotted carrier guide il'or holding the carrier chain in the desired shape and position, conf sisting of a bonshaped channel having bottom, front and rear walls which receive and guide the carrier chain, and carrier chain pinions at corners of the carrier guide for holding .it in shape.
