DEVICE FOR 'DISPLAYING- MERCHANDISE.

To all whom it may concern:

Be it known that we, GEORGE J. Bick- NELL, of Hull, in the county of Plymouth and State of Massachusetts, and WILLIAM @LIVER FVEBBER, of Brookline, in the county of Norfolk and State of Massachusetts, citizens of the United States, have invented a certain new and useful Improvement in Devices for Displaying Merchandise; and we hereby declare that the following is a clear, full, and exact description of the same, reference being made to the accompanying drawings, forming a part of this specification, in which similar characters represent corresponding parts in all the views.

This invention relates to a device for displaying' merchandise, and has for its object, means for consecutively removing from one position to another, a superimposed number of articles, and depositing said articles in sequence in a superimposed manner, in a second location horizontally located in reference to the first location, together with means for subsequently reversing this operation, returning the merchandise in the same manner from the second location to the original location, with means for interrupting these operations at any stage and reversing the operation in either direction at will.

'ihis device consists of certain novel features of construction and arrangement of parts which will be readily understood by reference to the description of the drawings and to the claims hereinafter given.

Of the drawings, Figure 1 represents a plan view, Fig. 2 represents a partial sectional elevation on line 2-2 on Fig. 1, Fig. 3 represents a vertical elevation showing the leveler guides in detail. Fig. 4t represents a vertical elevation. Fig. 5 represents a plan of the leveler mechanism on a larger scale and in greater detail than is shown in Figs. 1 and 8. Fig. 6 represents a transverse section of the supporting rod, gripper rod and gripper foot with an alternative form of gripper to that shown in Fig. 11. Fig. 7 represents the gripper cam in detail. Fig.

8 represents one end of a supporting rod showing the gripper rod, gripper cam, supporting rollers, gripper foot and gripper, in vertical section. Fig. 9 represents a sectional elevation of one of the vertically moving blocks showing in detail the cam actuating pins, and mechanism forI operating same in detail.

Specification of Letters Patent.

Application led March 29, 1909.

Patented Mar. 8, 19111.. serial no. ese/iss.

Similar characters designate like parts throughout the several figures of the drawings.

ln the drawings 10 represents a platform superimposed upon any fioor or base line. 11 represents two shafts mounted upon stands at opposite ends of the longest dimension of the platform 10. 12 represents two endless working chains, actuated by sprocket wheels 13, mounted upon shafts 11, one part of the chains 12 passing above, and the other part below the surface of the platform 10. The shafts 11 are actuated by a motor 14, driving chain 15, and driving chain 16, for the purpose of allowing the upper part of the working chains to remain slack when operated in either direction.

The working chains 12 are .carried by means of rollers 17 mounted upon rods 18 operatively attached to the chains at opposite ends.` The working chains 12 are caused to pass between rollers 19 operatively mounted upon sliding blocks 20, which have a free vertical movement in

stands

21 and 22 which are adjustably attached to the platform 10. Upon the blocks 2O and 20a are carried pins 23 and 24. On the outer tubes 27 of two of the carrying rods 18 are on mounted grippers and near the ends of the tubes carrying the grippers are gripper cams 26, which engage the pins 23 and 24e.

The carrying rods on which the grippers are mounted consist of an inner rod 18 and an outer tube 27. The gripper 25 is ixedly secured to the outer tube 27. rl`he gripper foot 28 is in two parts and is secured by passing through the gripper rod 18. The upper part of the gripper foot 28 acts as a guide for a spring latch 29 operated by spring 30. Attached to the lower ends of vertical moving blocks 20a is a chain cord 31 which passes under sheaves 82 and around sheaves 38 carrying a rod which engages the bottom edges of guides 35 operatively hinged in guide bases 36 which are fixed to the top 'of platform 10, so as to canse the guides 35 to come in contact with guide rolls 87 which are operatively mounted upon rods 18 1nside of the working chains.

It is obvious that the motor can be stopped or reversed at any period of the operation at the pleasure of the operator. Longitudinal slots 38 are provided in the upper surface of the platform on opposite sides thereof, so that bound edges of the flat materials will not pile up unduly and interfere with the action of the roller and gripper rods.

The operation of this device is as follows: A plurality of flat merchandise is superimposed one upon the other on one end of the platform 10 and the motor 14E is started causing the working chains to move in a horizontal direction over the pile of the 'merchandise When the gripper rod 18 ar rives at the right hand edge of the pile of merchandise, it brings the cam 26 into contact with the pin 23 thereby causing a partial revolution of the grippers 25 about their aXis of support and the point of the grippers 25 pick up the right hand edge of said flat merchandise between them and the feet 28; at the same time the rotative motion of the gripper 25 forces back the wedge bolt 29 against the spring 30 and brings the right hand face of said wedge against the left hand face of the above gripper and the compression of the spring 30 forces the contact between gripper 25 and the foot 28 thereby firmly holding the forward edge of said flat merchandise. As the articles of flat merchandise are superimposed upon each other the rollers 17 and rods 18 will cause the sliding blocks 20a to assume a higher elevation above the surface of 'the platform and this in turn by means of the chain 31 will cause the guides 35 to assume a correspondingly greater elevation as the rod 3a is drawn beneath the lower edge of the guide 35, and the upper edges of the guides are brought into contact with the under side of the rolls 37, and t-he right hand or forwardly progressing edge of the flat merchandise is lifted, thereby admitting air underneath the lower surface of said merchandise thus reducing the friction between said bottom edge and the top or upper surface of the next succeeding piece of merchandise. Immediately after the gripper mechanism engages with the forwardly moving edge of the flat merchandise and begins to move it horizontally one of the roller rods 18 with the rollers 17 comes into contact by being superimposed on the rear end of the neXt succeeding piece of tlat material thereby holding it in a stationary position due to the weight of said rod and rollers. merchandise arrives at a pointopposite the stands 22 at the end of the platform, the gripperl 26 comes into contact with a pin Q1 which causes the gripper to mechanically release its hold upon the merchandise and it is thereby deposited. This operation will continue until all of the flat material originally deposited on one end of the platform, is transported to the opposite end of the platform, the motor then being reversed in its direction of revolution, the load chain is reversed in its movement, and the gripper-s are reversed by coming into contact with then the forward edge of the pins on the second set of stands causing the articles of flat material to be t-ansported back again and deposited in their original position. It is obvious that di'tl'erent terms of gripper mechanism may be employed, and in Fig. t3, gripper is shown with a double projection on the back in contact with the latch Q9, necessitating the alternate withdrawal of one each of pins 223 and 2l as the direction of the moving parts is changed', this is shown in detail in Fig. t), in which one of the rollers 1t) on each of the. stands 21 and is provided with sprocket teeth engaging the chains 12, and on the rear oi' the shaft on which this roller is iixedly mounted is a threaded portion 3T, one each of the threads engagiiig pins 28 and 2lbeing right hand, and the others left hand threads, with a clearance groove at either end; engaging with these vthreaded portions is an arm 38 iixcdly secured to the rear end of pins and L4A on which are mounted two springs 39 and l0 with a tixed collar l1 between them; these studs 23 and 2t are carried by plates 12 and rtI-3 at either end, these plates also serve as abutmcnts against which the springs 3S) and l() are compressed. The action in this case is as follows: vWhen the carrying chains 12 are moving` in one direction, the grippers are in the central position shown in Fig. t3, the cam 26 is in a vertical position, on approaching the tirst pin 2&3, the lower end oit' the cam engages the pin and the gripping action takes place; the sccond pin Q3 is withdrawn b v the mechanism described and shown in Fig. t); when pin llis reached, it engages the upper rearmost web of gripper QG restoring it: to a vertical position, thus releasing the gripper; the pin at the other end of the machine in this case being withdrawn. 0n reversing the direction of motion of the machine, the pins i223 and 21 previously projected so as to engage the cam as above described are withdrawn and the alternate pins 23 and 2l are projected instead and the action above described is reversed. The ad vantage of this form of construction is that the lower de pending points of the gripper 25 are not so liable to catch in any unevenness ot' the upper surface of the mercham'lise being` handled.
