AUTOMATIC nIsrLAY. DEVICE.

Application filed AugustS, 1923,:Seria 1No; 656,379;

My invention relates to ii'nprovements inexhibiting mechanisms, the object of theinvention being the provision of a mechanism automatically exhibiting one card or at actnne allowing the same to remain for s2 11' in viewposition a-predetermined time un'- til all cards or signs are displzjiyed; one at a. time, then returning the full pack of cards or signs to a starting position; this machine being constantly operated irom and by a suitable motor;

Another object of thi invention is to provide a simple and attractivedisplaying-machine oi this character wnich can use a large number of carriers whereby agreat variety of subjects may be displayed;

Another object is to secure the necessary card-shifting movement and not'disturb' the card displaying action;

or displaying means and operatively associated therewith a novel means restoring the-displaying means tonormal position;

Another object is to produce a device of s character which will be reliable in opout of working order;

1e01 the parts while other parts are opnoise;

With these endother ob ects 111 view, the

invention consists in certain novel i'eatures 5 oi COllStl'UCtlOIl and combinations and arrangements of parts, as will be more fully hereinafter described and'polnted out in:

the claims.

in referrin to the accompanying drawin 1 is a cross-sectional view ofmy'de vice with parts broken out for clearness;

2 is'a rear elevation of the mechanism: Fig.

and cabinet with the door removed. 2.- IS a detail view of the card carrying belt. 1 is the case for housing the working parts of my device which is driven by the electric motor 70 receiving power through the wires V out switch 9. The driving pulley 71. is attuched to the grooved pulley M'through the or object is to provide a novelcard- 7, both sidesbeing and have a minimum liability of peer object'is to insure the locking of ng, and to equalize the power and elim- 8 and 11, with a. controlling out belt 72. The groovetlpulleyeJ; to which is attached the pinion 49; botlrrotate on the 1 shaft 48; whichis rotatively attached *to the case 1, at 78. The pinion l9 meshes with the gear wheel 38, which is tied'tothecase 1 through-thebearing 40. The-lowenend oi" the connecting r0d18 lis pivoted torthe gear wheel 88, by the pin 87'; the upper end at 33 is pivoted to the lower end ofthe rack 10, rack 10 being guided on one side by the flanged roller bearings '12, which are rotatively attached to the; side of the;

case 1. The-otherside of the rack-10 having teeth 13 part way up its length; meshes with the pinion 25, which is attached to the gear wheel 22, both rotating onthe stub-shalt 81 which-is attachedto the case 1; the gear wheel-22 meshing witlrthe rack 35, the upperend of which is bent L-shaped at 1e, extending across the case 1, nuclearrying the U-shaped lugs 21, for holding the Calti wires 15, which are attached to the cards 19; the rack 35running inthe; groove down movement by. the guides 3 and 20. The bolts 51, made of metal or other suit guided'in their up and able material, having lu -s16 pressed outof the same leaving-the holes 76",11111' over thepulleys 18 which 'runon the stub-shaft 79, andover the flangedbelt wheels or pulleys .50, both 01" which are secured tothe- F 124. snar lo,

When the pinion 25 gets' to the-end of the teeth 13 M82, the pinion 25 is'heldin this positionby the friction clutch 23' until the rack is carried? down and upagain through that part of the same having no teeth, thus leaving the card l9' on displayduring'this period;

movement it carriesthe card 19 back to stor ing posit-ion, leavmg the ends of'the Wires and whenthe teeth in'pinion 25 again mesh with the rack 10 in 1ts upwardi which in turn" is pivoted to the sides oi? the easel at 78'. Thus startingthe motor 70, rotates the grooved'pulley 47, can

ence; so that a large number of cards may be .kept in compact arrangement in this space, always having sufliclent space for a H) properly raising and lowering a card 19, to

and from the belts 51 which are tied to the flanged belt wheel so they will not slip when power is'applied. The slotted lugs 36 are attached to the flangedbelt wheel 50 at 80,1and are so constructed that when the gear wheel 38, carrying thepin 37, rotates, this pin 37 will enter a slot at an angleto shift thegrooved pulleys 50, just far enough to put thesucceeding card in position to be carried by the .U-shaped lug 21 to displaying position After all cards have been displayed, one at a time in this manner, and at the last movement of the pin 37, entering the slot in lug 36, the pin 62 connects with the lever at61, forcing the lever 60, guided by the roller bearing 63, up, causing the levers 66 and 68, whichare pivoted at 69 and 67 and run in a slot over the pin 64:, to straighten up, forcing the rack 56, to mesh with the gear wheel 38, thus throwing all cards 19 back to starting, position, and

causing the pin 57 to connect with the lever 60 at 59, thus releasing the rack 56, which is attached to the flanged belt wheel 50 at 58, from the gear wheel 38, again allowing the cards 19 to be displayed'one at a time. It can be understood that when the weight of the card 19 is carried up by the motor 71,,the

motor having'more weight exerted against it, would run at less speed than when the card is going down; to equalize this weight I have employed a friction clutch 43, tied to the case 1 at 42, made of metal hollowed out in the center, into which is placed a spring 45, and a piece of fiber 41 shouldered at 46,.to hold the-tension ofthe spring 45,

and allowed to protrude farenough to drag on the cam'39, which is attached to and runs with the gear wheel 38, and so adjusted on the same as to cause a braking action when the card 19 is coming down. The end of the set'screw 44 connects with the spring45, allowing adjustment on the clutch 13, To insure the card carrying belts 51 remaining in the position from which the card 19 is raised until it is again returned, I employ a braking action on the sides of the belt wheel 50 on the bearing 73 which is attached to the case 1, to which is tied at 55, a T-shaped bar 58, having adjustable means for dragging 77 on the sides of the belt wheel 50, held-by the screws 52 and 54-. The motor is heldin place by a block 75, attached to the case 1, to which the motor bracket 7 1 is'attached. The bracket 26 is tied to the case Lat 27 and supports the screw 28 over which is a spring 29, the tension of which is adjusted by turning the screw 28, thus causing flat spring 31, which is tied to the case 1 at 32, to exert pressure against the fiber ring 23, on the hub 24:, at the proper time to hold the load to be carried by it. I
