" Figs. 7 to 10 are detail sectional views, at line '1-7 of Fig. 5, showing the parts in different positions.

In the drawings a dispensing machine is indicated which is known as of the column type, in which a plurality of stacks of similar articles, or packages to be vended, are arranged side by side. from each of which a single package may be dispensed by operating a corresponding hand ever.

As this machine, per se; constitutes no part of the invention claimed herein, only those parts are herein referred to which directly co- 'operate therewith.

g The entire machine is enclosed in'an outer casing 11, the front of which is removable to permit access thereto. The machine comprises a main operating shaft 12, which is mounted in the sides 13 of the machine, and a series of operating levers 14 are mounted on said shaft, the handles of which extend through the front of the casing. The shaft 12 is normally locked against operation by certain coin-releasedmechanism, not shown, and when released by the insertion of the coin, or coins, which the machine is designed to receive, any one of the levers 14 may be depressed from the initial, or normal position shown in full lines in Figs. 1 and 2, and, when depressed, will cause forward rotation of shaft 12 until the lever has been depressed to the limit of its movement indicated by the dotted line position of Fig. 2, then, when the lever is released, it will be swung back to its initial position and the shaft 12 will be rotated in the reverse direction, and likewise returned to normal position. This action will result in the delivery of a package to the bottom opening 15 from the stack corresponding to the lever which was operated. In all machines of this type a suitable pawl and'ratchet mechanism compels movement of the levers to their extreme positions before they can be returned to normal position.

As already indicated, the primary purpose of the present invention is to provide means whereby a certain amount of change may be returned tothe purchaser, after he has inserted the coins necessary to release the main operating shaft 12, so that a package may be secured from one of the columns of the machine at a less price than the amount of the coins originally inserted.

To this end aflat bracket 16 is secured to the left hand end 13 of the machine and is arranged with its top side horizontal, and a guide plate 18 is secured on the top side of said,bracket, said plate having its middle portion recessed to provide a guideway for a dispensing slide 20, to which a handle 22 is attached, which extends through an opening in the front of the casing 11, sothat the operator may pull the slide outward. A coil spring 24 is attached to said slide and to the plate 18 and normally acts to hold the slide in its normal, or retracted position of Fig. 2.

In the present instance, the slide is designed to dispense, on each reciprocation thereof, a coin or a plurality'of coins and also a card of matches.v To this end, an'aperture 19 is formed in. plate 18 of a diameter slightly greater than the diameter of the coins to be d p nsed, and

a coin tube 25, having an'internal diameter approximately the same as that of aperture 19, is mounted vertically on said plate in register with said aperture, said tube in practice extending to the top of the outer casing and being filled with a stack of coins X, as indicated. A square tube 26 is also mounted on plate 18 directly in the rear of tube' 25, the internal dimensions thereof being made to correspond to the ordinary card of safety matches generally used by smokers, and said tube is likewise filled with a stack of match cards Y.

The slide 20 is of the same thickness as the coins which are to be dispensed and an aperture 21 is formed therein, also of the same diameter as that of aperture 19.

A pair of fingers 28 areformed on the rear, or inner end of slide 20, and are so arranged that they engage the bottom side of. the bottom card in the tube 26 when the slide 20 is in the normal position of Figs. 2, '7 and 9. The bracket 16 has an aperture 17 therein with which the aperture 21 of the slide registers when the slide is in normal position. A hopper 30 is provided on the end wall 13 of the machine directly beneath the aperture 1'7 and the rear end of the slide 20 and is connected to an opening in said wall, so that an article delivered thereto will slide down to the front opening 15, where it may be secured by the purchaser.

As thus arranged, when the slide 20 is drawn forwardly to its limit, the aperture 21 therein will come into register with the aperture 19 and the bottom coin in the stack will pass into the aperture 21, so that, when the slide is retracted, the coin will be carried back from beneath the stack andwill fall through the aperture 17 into the hopper 30, as shown in Fig. 9, and be delivered. Also when the slide 20 is drawn forward to its limit, the fingers 28 will be withdrawn from beneath the stack of match cards, as shown in Fig. 8, so that, when the slide is retracted, said fingers, the black sides of which are vertical, will engage the edge of the bottom card in the stack and push. it from beneath the stack, so that it will be delivered to the hopper 30, as shown in Fig. 9. I

It will be apparent, that, with the construc-- tion as'thus far described, the contents of the tubes 25, 26 could be discharged into the opening 15, by merely reciprocating the slide 20 repeatedly. It is, however, desired that it shall be possible to reciprocate the slide only once after each operative movement of one of the handles 14. To this end a post 32 is rigidly mounted in the slide 20 and projects from the under side thereof down through the bracket 16, and the latter is provided with a slot 33 in whichsaid post may be moved when the slide is drawn forward. A locking dog 34 is mounted on the under side of bracket 16 by means of a pivot 35, and spring 36 is engaged with a pin 37 in one end of said dog and normally holds a finger 38 at the opposite end of said dog in engagement with the face of an abutment lug 40, formed on the under side of bracket 16, as shown in full lines in Fig. 5, in which position the dog extends across the path of movement of the post 32, so that a slight forward movement of the slide 20 will carry said post into engagement with said dog, which will prevent further forward movement of the slide, the

dog thus normally ting to lock the slide against operative move ent. A latch 42 is pivoted on the under side of bracket 16, so that it 50 I so . is held directly beneath the dog 34, and a coil spring 43 is engaged with one end of said latch and normally holds the end of a tapered finger 44, at the opposite end of said latch, against the face of abutment 40, as shown in full lines in Fig. 5. In this position the finger 44 extends across the path of; the post 32 and presents on inclined cam face 45 in position to be engaged by the post whenthe slide 20 is moved outward and a similar face 46, which ;is in position for engagement by the post as the slide moves inward. As thus arranged the post may push 'the latch aside as-the slide 20 moves either-outward or inward, but Willengage the side of the finger 38 on the dog 34 before it engages the face 45. s

An arm 48 is fixed on the end'of the shaft 12 which projects through the side wall of the machine, and projects perpendicularly therefrom, the normal or initial-position thereof being shown in Fig. 2 and the arrangement being such that, when the shaft 12 is rotated forwardly at the time the dispensing operation is performed, the arm 48 will be swung forward parallel with-and close to the edge of the bracket 16. .In the normal, or locking position of the dog 34, the end thereof in which pin 37 is mounted projects beyond the edge of bracket 16 into the path of the arm 48, so that, when said arm is swung forward during-the initial portion of the main dispensing operation, it will engagesaid end of said dog and swing it to the dotted line position of Fig. 5, in which position the opposite end of the dog will be carried to one side of the path of the post 32,

* so that the dog will thus be moved to an inoperative position, in which forward movement of the slide 20 will be permitted. The latch 42 is provided with'a pin 50, which projects in position to be engaged by the finger 38 ofv the dog, so that, as the-latter is swung out of locking position by the arm 48, the finger 38 will engage the pin 50 and swing the latch aside, but as soon as the finger 38 is swung past the pin 50, so that they become disengaged, the latch immediately returns to its normal position. Consequently, when the.arm.48 is swung back out ofengagement with the dog on its return movement, so that it will no longer act to' prevent return of the dog to normal position, as the dog starts to return, its finger 38 will-become engaged with the pin 50 of the latch, preventing -further return movementof the dog, which will thus be held in its inoperative position by the latch. While the dog isheld in this position, the slide 20 may be pulled forward and when released, will be drawn back so that it will perform its dispensing operation as already described. As the slide is moved forward, however, its post ,32 engages the, face 45 of the latch and pushes the latter '-aside"until it releases the dog 34, which will then be free to return to .normal position,.but, by this time the post 32 will have been moved past the position in which it would be intercepted by the dog, so

that the forward movement of the slide will be continued, and; on the return movement, the

, post 3-2'will merely push the latch and the dog after it hasbeen drawn forward sufliciently to trip the latch and release the locking dog, and

before it has been drawn forward to the outer limit of its movement, a spring actuated pawl 52 is mounted on the bracket 16 in position to engage ratchet teeth 53 on the slide 20, and

prevent retraction thereof,.until, when the outer limit is reached, the pawl becomes disengaged from the teeth and permits the return movement. Similar arrangements are commonly emplayed in dispensing devices.

With the above described construction it would be possible, by first releasing the main dispensing mechanism, to depress a lever 14 until the arm 48 moves the dog 34 to its inoperative position, and then, by holding the lever 14 in this position, to operate the slide 20 indefinitely,

so that all the coins stored in the tube 25 could be removed. 1

To prevent such an occurrence, an auxiliary locking device for the slide 20 is provided, which comprises a hook 54, which is mounted on'the topside of plate 18 to swing about a pivot 55,

and is normally held by-a spring 56 in engage-' path of the arm 48, when advanced on depression of a handle, the arrangement being such that, when the arm 48-is moved from its initial position, it immediately engages the'edge of the hook 54 and causes itjto swing into a position in which its edge is fiush with the edge of plate 18, as shown by the dotted line position of Fig. 3, in which position its hook end will be in the path of movement of a lug 58 on the slide 20,

so that, if the slide should be drawn outward,.

its lug 58 would immediately become engaged with the hook 54 and the slidewould be locke against further outward movement.

The arrangement is such-that the hook 59 is moved into locking position before the arm 48 engages the dog 34 and moves it from locking position, and, as the arm 48 holds the hook in its locking'position during the entire time in which the arm is advanced and retracted,it will be apparent that the operation ofthe slide 20 will not be possible during any of the time in which the main dispensing mechanism is' in any of its substantially advancedpositionsh I The number of coins to bedispensed by each operation of the slide may be varied by varying the .thickness of the slide 20, that is, if two coins are to be dispensed, the thickness of the.

slide will'be approximately twice the thickness of the coins and if three coins are to be disness thereof. -It is, however, desirable to provide a simple means of adjustment to vary the number of coins returned, without changing the .parts. For example, in some instances it is desired to return one cent in change on certain days and two cents in change onother days from the same machine. To meet this requirement, a supplemental slide 60 is provided. directly beneath the slide 20, which is, or may be of the same thickness as theslide 20 and is otherwise constructed the same in all respects, except .as hereinafter noted, as theslide 20.

The slide 60 is provided with a lug 61 on its front end, and a simple button 62 is mounted ,135 pensed, it will be made three times .the thickthereon, which, when a single coin only is to be dispensed, is engaged with a lug 63 on the bracket 16, so as to hold the slide 60 in the retracted position of Fig. 9, in which position its coin aperture 65 will be in register with the aperture 21 of the slide 20, when the latter is in retracted position. The slide 60 is provided with a slot 66 in which the post 32 may move when slide 20 is drawn forward. When locked in this position, the slide 60 will have no function.

If, however, it is desired to readjust the machine to dispense two coins, the pivot screw 6'7 of button 62 will be loosened and the button will be turned out of engagement with the lug 63 and into a position in which it lies against the front side of a lug 68on the front end of slide20, to which the handle 22 of the latter is attached, as indicated by the dotted line position of said button in Fig. 6. As thus arranged, the slides 20 and 60 will be locked together and will function exactly the same as if the thickness of slide 20 were doubled. Other variations to secure similar results and dispense other amounts of change may be made in a manner which will be obvious.

With the above described supplemental dispensing device, existing vending machines may,

a at relatively small expense, be provided with means whereby they may vend merchandise at various amounts less than the amount at which it was originally intended to be vended.

I Also by employing said supplemental dispensing device in connection with the manufacture of dispensing machines of standard types, it will only be necessary to provide the latter with coin controlled mechanism to receive, for example, a dime, a dime and a nickel, or two dimes to enable sales to be made for various amounts up to four cents less than these amounts.
