8 Claims.

This application is a division of the copending application Serial No. 489,145, filed October 16, 1930, Patent 1,976,585 October 9, 1934.

This invention relates to a money delivering device in which the members, controlling the selective ejection of the different sorts of coins are controlled by perforated cards and consists in the provision of a common operating member and means for automatically rendering the latter operative by the presence of a card so as to cause the automatic operation of the card feelers and the coin ejecting control members of the coin disbursement device. In view of such provision the operation of the machine is considerably simplified and as its speed of operation is increased the efficiency of the machine is correspondingly increased.

In the, present invention it is immaterial whether perforated cards are used for controlling the coin disbursement device as the perforated cards may be replaced by equivalent arrangements, such as perforated strips, cards or plates with, registration indicating points, and. the like. Further, the manner of repre- 2 senting values by perforations or registration indicatingpoints of the cards or the like is quite immaterial to carry out the present invention. ,In the constructional example hereinafter described a perforated card is used in which each numerical value is represented by a corresponding number of successive holes arranged in a common row.

A device constructed according to the present invention is illustrated by way of example on 35 the accompanying sheet of drawings in which:-

Fig. l is a diagrammatic sectional View of the machine showing the machine in a normal position and Fig. 2 a similar view showing the machine in a partially operated position.

- Fig. 3 is'a detail view, 7

Fig. 4 shows a part of the perforated card and Fig. 5 is a sectional view taken on the line 5-5 of Fig. 1.

Several rows of feelers 2, corresponding in number to the kinds of coins to be paid out, are arranged in a casing I. Each row of feelers, related to a certain sort of coin, comprises nine pins. Springs 3, (Fig. 1) arranged 50 on the feelers, force the latter through a slid- .ably movable plate 4, which is provided with holes through which said feelers may project.

By means of a pin 1 coacting with an angular slot 6 of a plate 5, it is possible to move the "55 plate 4 for a purpose that will later be evident.

In Austria October 19, 1929 A second plate 8, provided with holes, is secured opposite the plate 4 and. likewise, has holes through which the feelers may project. The topend of both plates are bent away from each other and thus provide outside of the casing I a funnel 21 for the insertion of the card. The feelers of a single row are angularly disposed in a vertical plane in such a manner that their right ends may limit the upward movement of a coin ejector 9. The latter consists of a lever which is provided with a longitudinal slot and is first slidable and then rotatable on a pin Ill engaging said slot and fixed to an operating lever II. A spring l2 tends to retain the pin 10 in the bottom end of thelongitudinal slot of the coin ejector lever 9. Further, the lower end of the coin ejector 9 has a pin and slot connection to a lever 13, which in conjunction with a lever l4, fixedly pivoted at one end, forms a toggle lever. A lever l5, pivoted to the joining pivots of the levers l3-|4 is provided with a slotted and through which slot passes a pin 16 fixed to the operating lever H. A spring ll tends to turn the operating lever II in a clockwise direction about its pivot I8 so as to return it to its normal position shown in Fig. 1 after having been operated as shown in Fig. 2.

A slotted plate 20, (see Fig. 3) which forms a support for the coins inserted in the tube 2 I, is arranged opposite the hammer-shaped top end of the coin ejector 9 (Fig. 1). A sleeve or tube 22 slides on the tube 2! and rests on the top edge of the coin ejector. A funnel 23 is located opposite the coins of e a related stack and in connection with the corresponding funnels for the other sorts of coins they all terminaite in a common collecting funnel 24, underneath of which is placed, for instance, a wagereceiving bag 25.

The device operates in the following manner:--

The perforated card 26 is inserted, reversed with respect to the position shown in Fig. 4, through the card insertion funnel 21 of the casing I until its top edge (which now faces downward) engages with the center partition la of the casing. In this position the holes of the card are disposed opposite the feelers 2. For instance, if according to the card shown in Fig. 4 the sum of $26.23 is to be paid out, and if the group of feelers shown in the drawing serves for selecting the dollar units, the six holes in the card will be disposed opposite the six lower feelers 2. When the operating lever H is rocked counterclockwise by means to be subsequently described, the plate 5 moves downwardly to the Fig. 2 position and by the provision of the angular slot 6 the pin 1, and thus the plate 4, are shifted to the left. The plate 4 releases the feelers 2 so that, by the action of the springs 3, the feelers move toward the card and at the places where they find holes in p the card the feelers pass through the same. In the present case the six bottom feelers pass through the card, while the three top feelers engage the face. of the card as shown in Fig. 2.

During the further counterclockwise operation of the lever i i, the coin ejector 9 by means of the spring 12 is elevatedsofar as is permitted by the six feelers which have been'withdrawn from its path of movement. The coin ejector is positively stopped by the seventh feeler. During the last phase of the counterclockwise movement of the lever H beyond. the Fig. 2 position the pin it cooperates with the top end of the slot in the lever l5 and forces upward the joining pivot of the two levers l3 and I4. Thereby, the coin ejector 9 rocks about the pin I and shifts six of the oppositely lying dollar coins into the funnel 23. After this operation is performed the lever II is returned to its initial position by the spring I1. Now the joining pivot of the toggle lever l3, I4 is depressed by the pin I6 as shown in Fig. 1 and the coin ejector returns to its normal position. At the same time the coin ejector is moved downwardly so that the coins in the tube 2! resting on the ejector 9 can slide down until they are stopped by the plate 2!]. Owing to the weight of the sleeve or tube 22 it participates in the downward movement of the coin ejector, so that the unwanted coins are protected against accidental dropping into the funnel 23. During the last phase of the return movement of lever II the plate 4 is shifted to the right by the reverse action of cam slot 6 on the pin 1 and thereby the feelers are forced out of the perforated card to the position shown in Fig. 1 and the latter can now be freely removed by the operator.

A feature of the present invention consists in causing the automatic operation of the operating member by the insertion of the card in the machine. This object may be attained for instance by providing a separate feeler, which is shifted from its position of rest whenever a card is properly disposed for registration with the feelers, and thereby renders operative automatically the feelers and the coin disbursement device.

When a card 26 is inserted in the machine to engage with the center partition la the said card cooperates with card actuated lever 28,

which is in frictional contact (see Fig. with a contact lever 29. Card actuated lever 28 is moved from the position shown in Fig. 1 to the position shown in Fig. 2 and shifts the contact lever 29 from its position shown in Fig. 1 to its position shown in Fig. 2 to close contacts 38 when the card is in the position shown in Fig. 2. Thereby current passes through the magnet 3|, which attracts the lever H and moves it in a counterclockwise direction. The latter, as previously described, causes the cooperation of the feelers with the card and the ejection of the desired coins. During the last phase of the counterclockwise movement of lever II an extension 32 of the lever H strikes against the contact lever 29, shifts it independently of the card'actuated lever 28 which is held in rocked position (Fig. 2) by the card to the position shown in Fig. 1 and against a pin 29a, and thus opens the contacts 30. In view thereof, the magnet 3| becomes currentless and the lever H returns into the initial position by the action of the spring l1. When the card is manually removed from the machine by the operator the lever 28 is returned to its initial position (shown in Fig. 1) by a spring 33 but lever 29 is prevented from moving by the pin 29a. The machine is now ready for the reception of the next card and the operation can be repeated.

Of course the number of the coin magazines and groups of feelers depends on the kinds of coins to be ejected by the machine. In the illustrative embodiment the vertical rows of feelers are arranged in such a manner that at their left they are separated from one another a distance equivalent to the vertical spacing of the rows of holes in the card, while their right ends are vertically separated from one another a distance equivalent to the separation of the coin magazines.
