invented certain new and useful Improvements in Check-Controlled Apparatus, of which the following is aspecificatlon.

' This invention relates to check-controlled mechanism, among the objects of the inven tion being the provision of simple and ef-' fective means of this, character which is positive and certain in action and which can be advantageously incorporated in vending and all machines where such mechanism can be employed.

The present application is a. division of that filed by us on April 21, 1913, Serial No. 762364.

In the drawings accompanying and forming part of the present specification we have shown in detail one of the several forms of embodiment of the invention which to enable those skilled in the art to practice the same will be set forth fully in the following description. lVe do not restrict ourselves to this disclosure; we may depart therefrom in several respects within the scope of the invention defined by the claims following said description.

Referring to said drawings: Figure 1 is a cross sectional View of the intermediate portion of a vending machine equipped with check-controlled mechanism involving our invention. Figs. 2 and 3are side elevations of said mechanism in different positions, a portion of the side Wall of the machine illustrated partly in Fig. 1, being shown in said two views.

Like characters refer to like parts.

' throughout the several figures.

As will be understood check controlled mechanism involving our invention can be employed in different connections, it being E. ERWIN coin on the coin-carrier for moving said locking-element into releasing position, and these parts may vary decidedly as to character. We provide in connection with the carr1er, means of a positive nature, Which also may be of any desirable type, by which surreptitious or wrongful movement of the carrier will be prevented, by reason of which beating of the machine in which the mechanism is embodied, cannot be secured through the improper action of the check controlled mechanism.

itis now proper to refer more in detail to what is illustrated in the drawings which as already stated is merely one exemplification of the invention.

In Fig. 1 is shown acasing 2, the sides of which support a rock shaft 3' to which is fastened at one end an operating member 4 which as illustrated consists of a crank and by which through the agency of a coin,

the shaft 3 may be advanced in a forward direction. Mounted on this shaft is a delivery member 5 which is in the form of a. shell and which is arranged (ina cup machine) under a stack of drinking cups. On the initial forward movement of the shaft 3 the lowermost cup of the stack is detached therefrom and drops into this delivery member 5 and on the final movement of the shaft the cup is carried to such point by the delivery member 5 as the shaft'moves forward, that it can be reached through an opening (not shown) in the casing 2. This is a brief description of the vending. machine shown in our prior application and is all that is required to understand the action of the check-controlled mechanism,

.which as will be evident governs the action of the shaft 3 and thereby of the delivery member 5. That is to say if a check or coin of proper kind is introduced into the machine it is adapted to secure the full forward rotation of the shaft 3 to effect first the separation'of a cup from the stack and afterward the dispensing of the cup to the individual who introduced the check into the machine.

F astened to the shaft 3 within the casing 2 is the disk 6 which constitutes a convenient form of coin carrier and above'which is disposed the chute or trough 7 secured to the .65 With the foregoing general observations side wall of the casing 2 over the said coin carrier or disk 6, the chute at its lower end having the laterally extending portion 8 to direct the check or coin into or upon a seat or recess as will hereinafter appear, of the coin .carrier or disk 6. In practice the upper open end of the channel or chute 7 will be in or opposite a slot in'the casing 2, so that the check or coin can be inserted into the receiving end of the chute or channel by the.

casing 2 below thechute or channel 7 It will be noticed that the tooth of the pawl 15 is normally situated a sli ht distance from the toothed portion 13 of the plate 9 by reason of which the coin carrier or disk 6 can move a short distance without interference by the pawl 15.- This movement of the coin carrier or disk 6, however, is not sufficient to move the shaft 3 an extent sufficiently to cause the action of the vending mechanism and thereby the delivery of an.

article but is enough, however, to cause a coin provlded there be one on the coin carrier 6 to hit the pawl 15 or move 11': entirely out of the path of the toothed portion v13.

In other words the locking member or pawl 15 is to be released by the coin and if there be no coin the disk 6 cannot be moved sufficiently to cause full movement of the shaft 3 and the parts connected therewith. The intermediate disk or plate 10 is recessed'or notched as at 17 to provide a seat for the check which is usually a penny or one cent, but which, when a coin, might be of any other denomination. The disk or plate 9 partially overlies 'thewecess 17, while the disk or plate .11 wholly overlies the same to prevent side movement of the coin while in the recess 17. This seat or recess 17 which is practically channeled, is normally opposite the delivery opening of the chute 7. The locking pawl 15 is provided with a coin-operable portion 18 which as shown, consists of a stud or pin extending laterally from said pawl and in the path of the coin. It will be assumed that a coin has been discharged from the channel 7 and that it has been received in the seat 17 At this time it will be partially under and approximately against the stud or projection 18 which as will be inferred extends across the seat 17 although above the same. The toothed end 14 of the pawl 15 rests against the cut away portion 12 of the plate 9 a little distance in advance of the toothed portion 13. With the coin in the pocket or recess it will be clear that if the disk 6 he turned through. v

the forward movement of the shaft 13 by the operation of the crank 4, said disk will carry the coin therewith and the coin by acting against the stud or projection 18 will lift the pawl 15 out of the path of movement of the toothed portion 13, by reason of which the upper forward movement of the disk 6, the shaft 3 and delivery member 5 can be accomplished. On the return of the disk to its initial position the pawl will automatically resume its primary relation, and we might merely depend upon gravity to accomplish this but to facilitate such action a spring as 19 may be provided, one end of the spring being connected with the short branch or tail of the pawl 15, while the other end is connected to a stud 20 on the casing 2.

Means are provided for positively preventing backward movement of the disk 6 while the locking pawl 15 is in its releasing position as at such time if such backward movement could be accomplished it might be possible to secure several cups or other articles for the price of one. This means may be of any suitable kind, although that shown and now to be described is satisfactory. The circumferential projecting portion of the outer disk or plate 11 is shown provided with several teeth 21 arranged in arcuate order, the are being struck from the axis of rotation of the disk and the several teeth therefore presenting in effect a circular or curved rack. Cooperative with the teeth 21 is a detent 22 pivotally supported between its ends by the pivot 16 for the pawl or latch 15 and held in its. normal relation in some suitable way as by the spring 23 connected therewith and also with the pin 24 within the casing 2. On the advance ofthe disk 6 in the manner set forth, the first of the series of teeth 21 will engage the lower portion of said detent 22 and will swing the same forward so that it can enter the space between the first and the second of said teeth 21 backward movement of the disk 6 and parts connected therewith being prevented as long as the detent 22 is between any of the two teeth 21. As soon as the disk has reached its extreme forward position at which time an article will have been vended or some equivalent act performed, the detent 22 will engage behind the last ofthe teeth 21, the coin at this time having passed from the disk so that the disk can be returned to its initial position by the spring 25, connected therewith. On the re turn movement of the disk 6 the detent 22 will successively enter the spaces between the teeth 21, so that after said disk 6 and parts connected therewith have commenced their backward or return movement it will Fig. 2 the not be possible to move them forward until after they have reached their original position or practically so or at least up to the point where it is necessary to introduce a coin to obtain a second cup. Return movement of the parts, therefore, is prevented. until they have made their full advancing movements and vice versa, in view of which it is not possible to beat the machine. In parts are all in their primary positions. In Fig. 3 the detent 22 in full lines is between the first and second of the teeth 21 but in dotted lines it is shown b0 the detent is caused to rotate out of the teeth spaces so as to permit return movement or forward movement either for that matter. If anything short of a full movement in either .direction is attempted the detent is immediately moved into a tooth space so as to block effectually wrongful movement.

What we claim is:

1. The combination of an oscillatory disk consisting of several plates rigidly connected together, the intermediate plate being notched and the outer plates overlying the notch, the notch constituting a coin seat, and a locking member for the disk, one of the outer plates being toothed to cooperate with said locking member to prevent full advancing movement of the disk, the locking member having a pro ect1on extending across the notched portion of the intermediate plate and in the path of the coin in said seat, the other outside plate having teeth to present a rack, and a detent to cooperate with said rack to prevent backward movement of the disk.

2. The combination of an oscillatory disk, consisting of several plates rigidly connected together, the intermediate plate being notched and the outer plates overlying the notch, the notch constituting a coin seat, a locking member for the disk, one of the outer plates being toothed to cooperate with said locking member to prevent full advancing movement of the disk, the locking member having a projection extending across the notched portion of the intermediate plate and in the path of the coin in said seat, the operative portion of the locking device being normally spaced from said toothed portion, the other outside plate having peripheral teeth to present a rack, and a detent to cooperate with said rack to prevent backward movement of the disk.

In testimony whereof we affix our signatures in presence of two witnesses.
