CARD-DISPLAY-ADVERTISING MACHINE.

Application filed March 7, 1927. Serial No. 173,424.

This invention relates to a card display advertising machine of a type in which the cards are picked up one at a time, lifted out of a receptacle containing a number of such cards, displayed for a few seconds, or as long as may be desired, returned to the receptacle and again picked up in succession, the cards in the present instance being picked up from the front of a pile of cards and after being displayed for a short time being then restored to the card receptacle at the back of the entire set of cards.

Means are also provided to hold the cards in place on the card support positively during a portion of the card movement to prevent them from being dropped during another portion of the movement of the arms for dis playing the cards. The arms push them back into the card receptacle without regard to the lifting device which thereafter engages the front card of the series to present it to the public upon the next upward movement of the arms.

An object of the invention is to provide a type of reduction gear drive which can be arranged in a very small compass and which will make no other reduction gear necessary, the present reduction gear being entirely enclosed within an oil proof case.

Another object of the invention is to reduce the operating mechanism to the smallest possible compass in order to make it possible to produce the machines as cheaply as possible, and at the same time to make it possible to run them upon the minimum of power, a small electric motor being used for the purpose of driving the machine.

Other objects of the invention will be apparent as the description proceeds.

an embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout the several figures of the drawings and of which there may be modifications.

Figure 1 is a back view of the case and motor supporting stand, some of the parts being shown in cross section.

Figure2 is a sectional end view of the casing for the machine showing the end of the motor supporting stand and other operating parts, and i F1gure 3 is a detail plan view showing the arrangement of the worm casing taken on line 3-3 of Figure 1. k

The numerals 1, 2, 4 and 5 represent the bottom and sides of the receptacle containing the operating apparatus, 6 representing the top which has slots therethrough to permit the operation of the card lifting arms, and the top also has an opening through which the cards are removed from, andrestored to the card receptacle formed by the side 2 and partltion 3. i

The operating mechanism is mounted upon I a small bench 7 which has four legs 8 to 11 inclusive, said bench having a small rectangular box 12 adjacent one end to act as the gear box for the two sets of reductiongears. This gear box has a fiat cover 13 to retain grease therein, and it has bearings for a shaft 14 with a coupling 15 to beconnected with the motor couplings 16 on the motor shaft 17, which motor shaft projects from the motor casing 18, the motor being of just the proper ported by a shaft 22 at right angles tothe line of direction of the motor shaft, and it carries a worm 23 which in turn in meshwith the worm wheel 24, this worm wheel being carried by the shaft 25 which is journalled in the sides of the gear casing and projects therefrom to carry the cam 26 and commutator 27 The cam 26 is something in the nature of a heart shaped gear in that its movement first causes the arms it lifts to rise to a given maximum, then to remainin that position for a considerable period of the movement of the cam, after which the arms areraised slightly stantially similar rectangular frame 28, said frames forming the support in which the shaft 31 is journalled. Theshaft 31 carries the two arms 32 and 33, which arms are rigidly connected to said shaft and one of which has a depending extra supporting arm 35 to form a proper support for the bearing roller 36 which roller bears upon the topfof the cam 26 and forms the means for the continuous raising and lowering of the display cards.

The arms 32 extend over the top of the box, and they have depending hooks 38, one for each arm, which forms the means for engaging eyelets in the display cards and to lift them into the display position.

On the side of the arms there is a substantially L shaped plate 39, the depending arm of which is curved so that awn] bear upon the roller 31 and hold it normally in the position "in Figure 2, but during the time the transfer of the lower edge of the card is being made from the front edgeof the bundle to the back edge of the bundle it is very necessary to prevent the card from being dislodged from the hook 38, and this is accomplished by allowing the depending curved arm of the member 39 to recedeagainst the roller 31 at the curved portion 40. This allows the end of the member 39 indicated at 42 to come against the card and prevent it from being unhooked' momentarily, but as soon as the lower edge of the card has been brought back against the depending spring plate43 which extends from the top of the casing in which the apparatus is assembled down into the card receptacle between the side 2 and partition 3, the plate end 42 promptly releases the card and permits it to be removed from the hook while the arm at the same time operates with sufficient. force to push the card down into place against some little resistance.

The commutator 27 may have a separate commutator plate 27, and may be connected with two or four electrical connecting plates 4:7 to inclusive, as may be required, said contacts being carried by an insulated block 51 secured to the top of a small bracket 52 held in position by thenuton the bolt 30.

In operation, the cards are all kept in alignment by means of a thin piece of spring metal 53 at each end of the card compartment, and the cards are illuminated by means ofa lamp .54 which is held in the desired placeby the springs 55, 56, which also serve as the means for applying the electric current to "the lamp.

A reflector 57 extends along the front of the machine to prevent the lamps from interfering with a proper view of the cards by persons who may be looking at the advertising machines while they are working.

The operationof the machine is as follows: Assuming a plurality of cards to be placed in the card receptacle, said cards being held back by means of the spring 5 .6, and forward as much as they should be bymeans of the spring 46, the operation of the motor will cause the worms to operate their corresponding worm wheels at a slow rate of speed to cause the heart shaped cam :26 to rotate slowly. This cam will bear upon the roller 36 and will successively raise the arms 3E333 and lower them. As the arms 3233 are raised the hook 38 on each arm will engage a corresponding hole in a card in the receptacle. The card will be lifted out and displayed for a few seconds, after which it will be raised a little plate 39 will be placed against the edge of the card to hold it in place. The card will be held positively on the hook 38 only during the time its front edge is transferring from the front pile of cards to the back of the pile of cards, whereupon the plate 39 will be disen' gaged from the cards and they will be free to be removed from the hook 38, bntat the same time the arms 32 and push them down into the receptacle therefor, and when the arms do come down into a position to push the display card back into its place, the hooks 38 on each arm will at the same time pick up a new card from the front of the pile. At the same time the cards are being displayed the lamp 5% is having current supplied thereto and discontinned therefrom to increase the attractive appearance'of the cards and machine and the operationof the machine is cyclic, a card heing picked up, displayed, returned to the card receptacle, and a new card picked up. continuously.

Having thus described my invention, what I desire to secure by Letters Patent of the United States is as follows, but modificatitms may be made in carrying out the invention as shown in the drawings and in the above particularly described form thereof, within the phrview of the annexed claims.

I claim:

1. An advertising machine comprising a aising, a frame therein, a motor mounted on the frame, a reduction gear set to which the motor is directly coupled, a continuously rofixed position for a time, and then lower the arms and restore the card to the card receptacle.

2. An advertising machine comprising an enclosing casing having a card receptacle at its front portion, springs to hold cards in the desired position in said receptacle, a pair of arms each having a hook adapted to pick up a card by means of eyelets therein from the 10 front of aseries of cards placed in the card receptacle, means on said arms for securely holding the card thereon during a portion of the card movement, and means to raise the card a little higher whereby the card is restored to the card receptacle at the back of the series of cards following every display thereof.

In testimony whereof I have hereunto set my hand this 25th day of Feb, A. D. 1927.
