'Applicati 21 Claims.

This invention relates to exhibiting devices, particularly to those which include a movable endless strip or web upon which appear advertisements or other matter to be exhibited.

One object of our invention is to provide a v device of this character which is adapted to utilize a relatively long endless strip in a comparatively smallspace. A further object is to provide a device of this character with a specially constructed hopper for containing or storing loose or excess portions of the moving strip and a further object is to provide an arrangement of parts such that the strip is fed into the hopperby gravity.

A further object is to provide a novel arrangement of rolls for guiding and for moving the strip and also means for preventing entanglement of the loose portions of the strip by the guiding and actuating rolls. 7

A further object is to provide an improved exhibiting device having a window or opening behind which the movable strip is passed; for exhibition, vertically upward or in a direction toward the top of the sign, printed or other matter appearing on the strip.

' A further and important object of our invention isto provide an improved means for accurately aligning the strip asit is fed out of the hopper ontosuitable guiding rolls, in its passage toward thedisplay window. In the specific embodiment of our invention herein disclosed, this object is attained by inclining the side walls of the hopper towardthe point from which the stripis removed, so:that-the side walls form a guiding means forithe strip to. insure accurate 7. positioning of the strip on theuguide' rolls.

Other objects of our invention include sim- ;plicity of construction, relatively small cost of .manufacture and durability and also to provide adevice of this character which is entirely automatic in operation .an-d requi-res. no attention for long periods of time.

Other objectsandadvantages of our invention will appear from the following description taken in .connectionwith the accompanying drawings which show one embodiment of the invention and, wherein:

Figure 8 is a schematic View showing a modification of the holding means for the tapes which forms the hopper; and.

Figure 9 is a fragmentary view similar to the bottom of Figure 2 but showing a modification.

The mechanism of the exhibiting device is 'contained in a casing or cabinet I shown, for example, in Figures 2 and 3, which casing may be made of wood or other suitable material andis formed with an opening II atits front closed by a pane of glass l2. Reference character 14 represents the strip or sheet having the advertising matter thereon and which is adapted to be moved upwardly immediately behind the win-. dow ll.

Adapted to carry the strip M as well as the mechanism for moving and guiding the same is a frame l9 which is removably mounted in the cabinet and comprises a base I3, front and back inverted U-shaped frame members I! and .15 respectively suitably secured by bolts 18 to the base I3. Members [1 and. i are connected by inclinedside walls, [6 and it will be seen that. the uprights of the U-shapedmember. I! are spaced farther apart than are the uprights of member 15 and. the walls It are inclined toward each other rearwardly for a purpose which will be more fully explained hereafter. T

Means for moving the strip comprises an elec- H tric motor 20 mounted on top 'of the frame member H. The shaft ofthe motor20- carries a pulley or sprocket wheel 22 overwhichpasses a belt or. chain 23 engaging .a small'pulley. or sprocket wheel 24 mounted on one end of a stub. shaft 25 journaled in a bearing '26 supported from the inner side'of oneof. the uprights of frame member IT. Secured to 'the opposite. end of the shaft-25 is a, roll for moving the strip Hi; this roll at its far end carrying astub shaft o 25 journaledin a bearing 26' supported from the inner side of the opposite upright of the member H. The roller'30 has a rubberfacing 3| which isinter-rupted at intervalaas shownin .Figures 4 and 6 to form annular recesses 3 2 for a purpose hereafter to be explained. Mounted adjacent and parallel to the roll 38 is a roll 34 having rings or collars 35 of rubber or similar material. The roll 34 is an idler roll mounted at opposite ends on arms 31 pivoted at 38 on the opposite uprights of frame member I! and normally urged toward the roll 30 and into contact with the strip I4 by means of springs 39 secured at one end to the upright and at the opposite end of the lower end of arm 31.

Rotatably mounted in bracket bearings 40 immediately below the brackets or bearings 26 and 26' is a roll 4| over which the strip M passes and below this roll 4! at the bottom of the upright portions of the member I! is a roll 42 beneath which the strip passes in its travel to a position immediately behind the window H. To the rear of roll 42 is a roll 44 beneath which the strip 14 passes on its way to' the upper roll 4 I.

Mounted at the rear of the frame 19 near the top of the inverted U-shaped member i5 is a roll 5| over which the strip passes as it is fed out of the hopper and mounted near the lower end of the member l5 of the frame i2 is a roll 52 beneath which the strip passes in its passage from rear roll 5| to the forward roll 64.

The space between the rear rolls 5| and 52 and the front rolls as will be seen forms a container adapted to hold a relatively large quantity of loose strip which is fed downward thereinto from the feeding roll 30. The passage of the strip from the hopper is as follows: Leaving the hopper it passes upward over the roll 5!, thence downward under the roll 52, thence under roll M upward over the top of roll il, thence downward under the roll 42, thence upward past window H and over the roll 38 and between the roll 39 and the idler roll 34 downward into the hopper. By tapering the hopper rearwardly to a narrower width equal approximately to the width of the strip [4, the hopper provides ample space into which the strip passing over roll 30 may fall freely into natural folds and at the same time be guided by the sides of the hopper into proper position on the roll 5!. It will thus be seen that the apparatus is adapted to utilize a strip of considerably greater length than the distance around all of the rolls.

In order to prevent loose folds of strip contained in the hopper from being enmeshed or entangled by the moving rolls 52 and M and the moving strip which is passing under these rolls, I form these rolls and the roll 5| with cutout portions 60 which, if desired, may be formed by interruptions in the rubber facings of the rolls, these interruptions or annular recesses being arranged along the length of the rolls and in line with the recesses 32 in roll 30. I secure to the rolls 5! and 30 pieces of tape, wire or similar strips 63 which at their ends are looped around these rolls 5 5 and 30 in the recesses and sewed or otherwise secured such as at 55. These pieces of tape extend beneath the rolls 52 and 4| in their respective recesses. I have shown in Figure 1, three pieces of tape. Also at the

rolls

52 and 44, I provide additional pieces 66 which pass over the rolls and are sewed above and below to the main section of tape. these tapes in eifect form a hopper for loose or excess strip and also prevents the loose portions of strip being drawn in by the rolls or by the guided portion of the moving strip.

When the length of the strip is but slightly in excess of the distance around the rolls, the strip will form a single fold or bend in the hopper It will be thus seen that and if desired, under these conditions, I may sup port a floating roll 10 by, and in, the fold as shown for example in Figure 9.

In the modification shown in Figure 8, instead of passing the tapes under the lower rolls, I provide two rods 68 mounted respectively in the members l5 and I! under which rods the tape passes.

It will be noted that the hopper extends substantially the full length and Width of the cabinet and therefore has a relatively large capacity.

Suitable means not shown may be provided for controlling the motor either to cause it to operate continuously or intermittently. It will be seen that by causing the strip to move behind the window vertically it is possible to use a relatively wide strip with a large amount of printed matter thereon, the movement of the strip presenting this matter to View in the order in which it is read.

Bearings

26 and 26 at opposite ends of roll 30 as well as the bearings at opposite ends of each of the other rolls are preferably of the self-aligning and self-lubricating type.

If desired, suitable means may be provided for illuminating the strip.
