POBATION OF DIELAW msrnusme MACHINE.

Application filed February 5, 1927. Serial No. 166,046.

This invention relates to coin released dispensing machines of the type in which a circular tray having a series of delivery chambers is mounted in the bottom of a magazine and is intermittingly rotated in one direction, so that the chambers are successively moved into a delivering position, and, more particularly, to the operating mechanism for driving the tray.

As machines of this character are likely to be placed in positions in which they are unprotected, they are liable to be pilfered, unless the construction and operating mechanism is of a character to prevent it. For example, the intermittent action of the tray is usually secured by means of a reciprocatory or oscillatory mechanism, which is actuated by means of a handle. This mechanism is usually locked against advance beyond a certain point, and, when unlocked and advanced beyond this point, must usually be advanced to the extreme limit of its mot-ion before it is permitted to return. As the tray is disconnected from the actuating mechanism during the return motion, it is possible, with certain constructions, to work the tray back and forth, so as to empty the machine, by inserting some instrument thru the article delivery passage, while the actuating mechanism is held in a certain position.

The primary objects of my invention are to produce a coin releasable mechanism of the general type above indicated, in which it is impossible to advance or'retract the delivery tray independently of the actuating mechanism and in which the trayis always locked against rearward movement and also against forward. movement except when moved by the actuating mechanism upon release thereof'by the coin operated means.

I accomplish these objects by means of the construction illustrated in the acc0mpanying drawing in which:

Fig. l. is a front elevation of the outer casing; of the machine.

Fig. 2 is a vertical sectional view thereof, at line 22 of Fig. 3;

Fig. 8 is a vertical sectional view, at lines 8-3 of Fig. 1. I

Fig. 4 is a detail view of a coin controlled,

lockingr wheel for the operating shaft.

Figs. 5 and 6 are detail views of a combined locking and actuating means for the tray.-

The main casing 10 is provided with a magazine in its upper portion in the bottom of'which a circular tray 11 is mounted to rotate about a vertical axis, to deliver the articles in the magazine to a discharge passage 12, as the chambers in the tray are brought successively to a predetermined position, as described, for example, in Du Grenier Patent #1,:362,152. The bottom side of said tray is provided with a circular series of'depending gear teeth 13, and a wheel 14 is mounted on a horizontal shaft 15 beneath the tray, so arranged that its axis intersects the axis of the tray at right angles, and is provided with peripherally arranged teeth 16, which are constantly arranged in mesh with the teeth 18 of the tray, so that when the wheel 14 is rotated the tray will be driven thereby.

A main operating shaft 17 is horizontally mounted in the front side of the casing and has a handle 18 on its outer end, said shaft l7being so arranged that its axis intersects the axis of shaft 15 at right angles. A coin carrying wheel 19 is secured on shaft 17, and a locking pawl 20 is provided, which is normally arranged to engage a tooth 21 on wheel 19 and prevent operative forward movement of the wheel, said pawl being ar ranged to be lifted to an inoperative position by a suitable coin when delivered to the wheel, so that a complete operative movement will be permitted. A double acting ratchet 22 is arranged to engage teeth 23 on wheel 19, so that. when the locking pawl 20 has been lifted to permit operative movement of shaft 17, this movement must be completed and then, when the return movement has been started, it must be finished or returned to the initial position before it can be moved forwardly again,

The gear wheel 14 is provided on its face side next the shaft 17 with a series of circu larly arranged, equally spaced fingers 24, which extend therefrom in parallel relation to the axis of said wheel, the number thereof; corresponding to the number of delivery chambers in the tray, and a cup shaped disk 25 is mountedonshaft 17 and has a segmen tal cylindrical rim portion 26, on the edge relation to the fingers 24 that any two ad-v jacent fingers will be held. in such close r 82, that its side edge 33 is perpendicular to proximity thereto that appreciable rotation of the wheellt in either direction will carry either one or the other of the adjacent fingers into engagement with said face in all positions of the shaft 17. In other words, theplane of the face 27 intersects the path inwhich the fingers 24 move when the'wheel 14 is rotated, as shown in Figs. 3 and 5,-and the rim'26cis so arranged that its edge or face 27 isalways held in a position in which it will be engaged by said fingers, so that rotation of wheel 14: in either direction independently is prevented, and whether the disk is in its normal or its advanced position. The rim 26 is provided with a notch 28, adapted to receiveany one of saidfingers 24, and a pawl 29 is mounted on a pivot 30, securedin said rim 26 at one side of said notch, said pawl being held in such a position byrav spring 31, which normally holds one end of the pawl engaged with a stop lug face 27 and fiush'with one side of notch 28 and its end portion projects axially beyond the face 27,'as shown in Figs. 5 and 6.

V The parts'are shownin their initial position in Figs. 1 to 5, and, in operating the machine, to advance thetray 11 one station,

or to the next delivering position, the shaft 17 'willbe. turned to the right and will. be

- unlocked by a suitable coin which has been that, on furthermovement, wheel 14 will be rotated in the direction of the arrow in inserted in the machine, so that the rotation maybe continued to the end of the operative movement. In the initial position of the parts, the pawl 29 is held in such relation to the wheel le'that, during the first portion of the movement of the shaft 17 it is inoperative. As the movement is continued the edge 33 of the pawl is engaged with one side of oneof the fingers 24, so

Figs. 5 and 6 andthe finger, which isengaged, will be carriedinto the, notch 28, as shown in Fig. 6. This movement is continued until the tray has been rotated to the next station, at which time the shaft 17 will be engaged with a suitable stop (not shown) and an article will be delivered from the tray; The shaft 17 will then be'i'otated backward to the initial position and, during the'return movement, the hackedge of the pawl 29 will engage the nextfin 'er 24 and be swung aside as it passes it and then will be returned to initial position. To avoid the possibility that the tray will'be moved from its.station,-or the deliveringposition to, which it has beeninoved, on the return tray is in, oradjacent, a delivering two of said fingers will be held in close prox-.

movement, as by reason ofthe engagement with a finger by the pawl, means for preventing such backward movement is provided, themeans shown being a pawl35 mounted on the frame and arranged to be successively engaged with a series of projections 36 on theback side of wheel l l-,the arrangement being such that, when'tne tray has been advanced to deliver ng position,

which it must be before the pawl 22 permits reverse rotation of shaft 17, the pawl 35 will be engaged with one of the projections 36,

so that the wheel 14 cannot be rotated rearward and the next finger 24 will be positively held in position. for engagement by the pawl 29.

However, whether such means for preventing rearward rotation of the tray is em tray arranged for intermittent forward ro-v tation and having a series of chambers arranged to make delivery successively at a predetermined point, an actuator arranged for oscillatory movement between an initial and an advanced position and having a Cir cular face arranged in a plane perpendicular to its axis, driving means for said tray of the actuating means under arranged for rotationabout an axis which intersects the actuatoraxis at right angles and having a series of axially pro ect ng, regularly spaced fingers corresponding to said chambers and circularly arranged to be moved in a PELlDlICQHCQIltllC with its axis and intersecting said face, so that when the position imity to said face and one or the other there of will beengaged therewith on rotation of the tray in either direction, and means whereby said actuator, on rotation to its advanced position, will be engaged; with one of said fingers tomove saidtray'to the next delivering position.
