ADVERTISING DISPLAY DEVICE.

Specification of Letters Patent.

Patented Jan. 19, 1915.

Application filed October 29, 1913. Serial No. 798,015.

To all whom it may concern Be it known that I, JosEPH ALFRED PROULX, a citizen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Advertising Display Devices, of which the following is a specification.

This invention relates to a mechanically operated advertising device of that class wherein advertising display cards or the like are arranged on edge in two groups within a suitable frame to expose the face of the card at each end of each group, the end card of one group being transferred to the other at the back and front alternately, so that each.

face of each card in the two groups is displayed for a sensible interval of time.

The invention comprises the particular construction of the card holding frames with provision to facilitate movement of the frames, both in the plane of the face, as when transferring from one group to the other. and in a direction normal to that face, as when traveling from back to front and from front to back in the groups.

Theinvention comprises also the mechanism by which the advertising card frames are transferred laterally from one group to the other with the necessary pause through a definite period of time for exhibit of the advertisement displayed on the several cards, and the manner pressure to the front of one group and to the back of the other, which spring pressure moves the card frames of each group to fill the space occupied by the frame transferred to the other group.

The invention is particularly described in the following specification, referencebeing made to the drawings by which it is accompanied, in which? Figure 1 is a. front elevation of the machine showing the same in its completed arrangement. Fig. 2 is a section taken substantially on the line 22-of Fig. 1, those frames on the right side being shown in plan. Fig. 3 is a detail view in the plane of line 3.-3 onFig. 1. Fig. 4 is a perspective viewof an advertising card frame. Fig. 5, an enla-rged detail showingthe relation of the card frame with its transferring chain, and Fig. 6 is a plan of the machine frame showing the gear arrangement. Fig. 7 is a detail section on the line 7+7 of Fig.- 2.

In these drawings2. represents an open of applying a spring frame within which two groups 3 and a of advertising card frames 5 are carried. Extending across the back and the front of the frame 2 and within it are upper and lower transfer rails 10, each composed of two light bars which at the ends, where attached to the frame 2, have distance pieces to maintain them a short distance apart to allow the transferring mechanism to project between them, Extending across between the lower transfer rails under each group 3 and 4 are cross rails 11 which sustain the card frames 5 and allow them to move backward in one group and forward in the other group along them.

Immediately outside the transfer rails 10, the machine,

both in the back and front of and projecting a short distance above them are face rails 12, against which the card frames 5 of each group are held by the pressure of a spring at the opposite end of the group, which spring will be described later.

In the line of division between the two groups 3 and 4, and at a distance from each face rail 12 corresponding to the thickness of a card holding frame 5, rollers 18 are mounted, which rollers may be adjustable in their distance from the face rail.

Within each card holding frame 5 an ad vertising display card 6 may be inserted in amanner providing for ready removal and change. Each frame has transverse rollers 7 in its upper and lower rails to facilitate movement along the transfer rails 10, and adjacent to these rollers are rollers 8 to bear on the cross rails .11 during movement along the rails. The rollers 7 should project a little farther out of the frame than the rollers 8, to sustain the latter clear of the rails 10 while transferring, and the upper side of the cross rails 11 should be slightly above the transfer rails 10. In the opposite face of each rail'of the card frame 5 a roller 9 is inserted at each end, which rollers are designed to relieve the frame of friction with the face rails 12 and with the adjacent frame while a frame is being transferred from one group to the other. The vertical edges of the frames are rounded, as at 14:, or are beveled from each face to facilitate entrance of the frame between the face rails 12 and the adjacent frame on the transfer from one group to the other. Secured to and projecting outward from each face rail 12 in alinement with the middle line of each group, studs 15 project outward from the front of one roup and from the back of" the other group. On each stud 15 a roller carrying bar 16 is freely mounted and is pressed toward the face rail by a spring 17. The ends of this bar are turned toward the face rail 12, and on each end a small roller 18 is mounted, each roller passing through an aperture provided forit in the face rail to bear against the outer face of the card frame. The action of this roller bar isillustrated on the right hand side of Fig. 1, where a card frame 5 is shown in the act of transfer in the direction of the arrow from the group 4 to the group 3. As will there be seen the edge of the frame is inserted, between the roller 18 and the roller 13, or the roller 9 of the adjacent card frame, and the springs 17 top and; bottom, are, pressed back withthe two to onefleverage of the roller bar 16, and as the leading edge of the transferring frame reaches the other roller 18, it is also forced back-with the two to one leverage, and the springs 17 then exert a distributed pressureover the width of the. frame, pressing all the frames of that group against .the face rail 12 at the back of the machine. As the face rollers 9 of the card frames are in one face of the top rail and in the opposite face of the bottom, rollers 38 should be provided in the top or bottom face rail 12,. as the arrangement may require, at the opposite end of each group to the spring rollers 18.

The transfer of a card holding frame 5 from the left hand group 4 tothe right hand group 3, at the front, and from the right hand group to, the left hand group, at the back, is effected by ing a projection 22 from one of its links which projection passes through between the transfer rails 10 and into engagement with either end of a recess 23 in the middle of the top and bottom rail of the frame 5 which may occupy a position on these rails;

One chain 20 is arranged under the lower and one over the upper rails 10 at the front of the machine and under and over the rails lOat the back and each chain passes around a jtriangularly arranged group of sheaves 21,24 of which 2 1- is a driving sprocket and 21 are only guide sheaves maintaining a length of the chain parallel to the rails 10..

i As shown in the drawing, the card carrying frames travel from left to right at'the front and from ri ht to left at the back and as "the top and bottom drive is taken from adjacent sides of the opposed chains, the

7 chains must travel in opposite directions of rotation.

r The alternating movement which'it'is desired shall be imparted to the card frames at the front and the back of the machin'eis attained by placing the engaging projection 22 of the top and bottomchains 20whiclr an endless chain 20 havmove the card frames at the back in an opposite position on the chains to what they are in the front. The chains 20 are operated from a first motion shaft 25 which de rives its movement from any convenient source of power, and the required period of movement alternating with a period of rest is derived from this shaft 25 by an endless chain 27 taking around a sprocket wheel 26 secured on the shaft 25 andaround a flanged sheave 28 secured on a shaft 80 rotatably mountedin the lower part of the frame 2 of the machine on oneside. The chain 27 passes loosely around this sheave 28, the flanges of which are provided with diametrically. opposed projections 32 to engage pins 31 projecting from certain links of the chain 27 at a distance apart equal to the circumferential distance apart of the projections 32 of the sheave. The chain 27 will thus move loosely on the sheave 28 without driving it until its pins 31 successively en-v gage the projections 32 of the sheavewhen the shaft 30 is rotated through a complete revolution, each. pin .hrotating the" sheave through a half revolution before leaving it. If a shorter period of rest between movements is required than is obtainable with 7 two pins in the length of the chain 27,.two

other pins may be provided at the required distance apart to give the period'of rest required. To insure that thedriving pins 31 do not free themselves from engagement with the projections 82 until each has completed the definite movement required of it, a guard 33 is secured to the frame of the machine which will hold the-projecting pins in driving engagement with the projections of the sheave until the full movement releases them from such engagement. The intermittent movement imparted totthis shaft 30 is conveyed to the several chains 20by a chain 34: taking around asprocket wheel 35 secured on the shaft 30 and around a similar wheel 36 secured on a shaft 37' extending across the other end of. the "machine. On

the other end of this shaft 37 is secured a sprocket wheel lO from which a chain e1 is carried around a sprocket .wheel42 secured to rotate with the driving sprocket 24: of the sprocket wheel at), around which passes a chain 47 which takes alsoaround the sprocket wheel 42 of the driving sprocket 2 1 of the lower chain 20' atthe front of themachine.

The interposition, of the' gears tiie l-reverses the direction of'i movemeiit of the:

lower chain-2O of the front of the machine from the direct drive of the chain. at the.

back. To convey a similar movement to the upper chains 20, a sprocket wheel 48 is secured on the shaft 37 around which sprocket a chain 49 passes and around a sprocket wheel 50 secured on a shaft 51 extending across the width of the machine at the top. On the front end of the shaft 50 is secured a sprocket wheel 52 which drives by means of a chain 53 the sprocket wheel 42 secured to rotate with the sprocket 24, which drives the chain 20 of the front of'the machine, and at the other end of the shaft 51 the direction of rotation is reversed by gears 54'55 secured on shafts 51 and 56 on the latter one of which is secured a sprocket wheel 57 driving by a chain 58 the sprocket wheel 42 'at the back of the machine. With this arrangement the adjacent or operative sides of the upper and lower chains 20 move in one direction at the front of the machine and in the opposite direction at the back of the machine. By different location of the driving projections 22 of the upper and lower chains 20 at the back, from those atthe front, the chain projections 22 of one set of chains will be in moving engagement with a card frame while those of the other will not. By the intermittent movement imparted to the shaft 30 each card frame movement will alternate with a period of rest, that is the chains 20 will all move together for a distance represented by a revolution of the sprocket wheel of the shaft 30. During one movement, the card moving projections 22 of the chains 20 in the front of the machine will engage and move a card holding frame from group 4 to group 3,

I during which movement the projections 22 of the chains 20 at the back of the machine are moving over their driving sprockets 24 and are not in engagement with a card holding frame. After a period of rest, the projections 22 of the front chains 20 will be traveling over their sprockets 24, and therefore out of engagement with a card frame, while the projections of the chains 20 at the back of the machine are in engagement with and are moving a frame from group 3 to group 4. A continual change of display from both faces of each card is thus effected, and the position of each display is changed from the face of one group to the face of the other, which change is advantageous from an advertising point of view.

The frame includes upper and lower partition bars 11 which carry rollers 13.
