To all whom it may concern).-

Be it known that 1, EDGAR H. Cook, of the city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Vending-Machines, of which the following is such a full, clear, and exact description as will enable others skilled in the art to understand and use the same when taken in connection with the accompaI- nying drawings, in which Figure 1 is a vertical sectional view of the machine on the line 11 of Fig. 2. Fig. 2is a top view of the machine with the top plate partially broken away on the line 2 2 of Fig. 1. Fig. 3 is a vertical section of the apparatus in its normal position ready to receive a coin, showing the coin in position in the coinholder. Fig. 3 is a detail view of the stop on the carriage which engages with the ratchet-bar. Fig. at is a vertical sectional view of the apparatus, showing the carriage part way pushed in and the delivery-arm raised by the presence of the coin and about to push from the stack a package. Fig. 5 is a like view of the apparatus, the carriage having been pushed all the way in,.so as to deliver the package. Fig. 6 is a vertical section of the apparatus on a plane at "right angles to that of Fig. 5 on the line 6 6, looking toward the back of the apparatus. Fig. 7 is a view of the apparatus on the same plane as Fig. 6, looking toward the front of the apparatus. Fig. 8 is a vertical section of the apparatus, showing an iron slug as held by the magnet;

and Fig. 9 is a like view of the apparatus,

showing the iron slug as being pushed from the magnet and dropping without'reaching the coin-holder,so that the apparatus is inoperative in the delivery of goods.

This my inventionrelates to that class 9 vending mechanisms in which the mechanism is inoperative for the delivery of goods by which the carriage may at all times be moved forward and back on a track or guide provided therefor.

The carriage has rigidly attached to it the.

push-rod I, which passes through a hole in the faceof the machine, and the slot-closer K, which moves forward and back directly beneath the slot when the carriage is reciprocated. The said slot-closer K comprises a horizontal shelf or ledge carried by the upper end of a movable stripping device S, hereinafter referred to, and being normally at the forward end of the apparatus in proximity to the slot, as shown, for instance, in Figs. 1 and 3. It also has rigidlyattached to it the coinguide lyl, so that it moves forward and back with the carriage. There is also attached to the carriage by the pivot O a bell-crank lever, which also moves forward and back with every reciprocation of the carriage. The bellcrank lever is composed of the delivery-arm N and the hook-shaped arm W. The hookshaped arm WV has at its extended end the cam Q, which comes in contact with the coin when in its position in the coin-holder V. It has also attached to it the retracting-spring P, which tends to draw the carriage into its normal position, as shown in Fig. 3.

' As herein shown, the coin-holder V is disposed or arranged above the pivoted lever,

with the slot or opening therein substantially in line with that end of the-cam Q upon which the lower edge of the coin first begins to act,

and it will be observed also that the said lever is formed with a bend W, the open end .or mouth w of which permits the passage of coins of less thickness than that of a given or predetermined coin. The side or edge of the bend W opposite to the cam extends somewhat above the cam and is so related to the cam that, as shown in Fig. 1, a coin of given thickness is prevented from passing through the mouth to of the bend, since it is caught and rests upon the lower edge of the cam and is held thereon by the cooperation with the cam of the opposite portion of the bend. A coin of less thickness, however, will pass down through the opening w, as will be plainly apparent from said figure.

To the bend \V is connected the inner end of the spring P, and the function of this spring is not only to return the carriage and lever to normal position, but also to exert a constant tendency upon the lever to tilt the delivery-arm thereof downward for a purpose to be described.

One of the objects of my invention is to drop the operating-coin into the receptacle therefor quickly and also not to depend upon the coin to keep the delivery-arm elevated during the full time of its delivery stroke. The reason for this is that if the coin were allowed to remain on the cam after the package is started from the delivery-opening by the delivery-arm it would be possible to first start the package by a very short movement of the lever and then to withdraw said package by hand, whereupon another package would descend, and so on, and in this way the packages could all be taken from the machine by the payment or insertion of a single coin. I therefore depend upon the coin solely to insure the tilting and partial advance of the delivery-arm, and I provide additional means for holding the arm in the elevated position to deliver a package from the stack. Thus I provide the deliveryarm at or near its lower end with a side pin or projection 1, which when the arm is elevated is received upon the upper edge of a stationary rest or support R, attached to the machine. Said support is of length corresponding to the required stroke of the arm, and beneath the support is a transverse guiderail Y, upon which the pin I normally rests and upon which also the lever and deliveryarm are guided in the return movement of the carriage. This guide-rail Y is also a stop for limiting the downward movement of the delivery-arm and lever after the former has completed its forward stroke in delivering a package. From the peculiar construction and arrangement of my improved apparatus it is evident that if some such stop device were not employed the delivery-arm and lever, as well as the cam, would be carried so far beyond the normal positions thereof as that the cam would strike the forward side of the coin-holder on the return of the carriage, and thus would the parts be rendered inoperative. The said part Y, therefore, becomes a combined stop and guide, and as such will be referred to hereinafter. The inner end of the rest or support R is beveled or inclined forwardly at 2 to facilitate the passage of the pin thereon, and the opposite end thereof is beveled or inclined rearwardly at 3, so as to guide the pin downward and backward on the completion of the stroke of the arm. It is apparent that by virtue of the pull eX- erted upon the bend W of the lever by the spring P the said delivery-arm is depressed or carried down upon the combined stop and guide Y immediately the end of the support or rest is reached, whereupon'the carriage is returned and the lever and arm carried back with it. Incidentally I provide the upper edge of said rest or support with a number of ratchets or teeth which are engaged by the pin 1, and in this way, after once being started, the lever and carriage are prevented from returning until after the delivery-stroke of the arm has been completed. The pin 1 is preferablybeveled at one end, as shown at Fig. 3", so as to enable the same to readily cooperate with the beveled or inclined edges of the ratchet teeth.

From the construction and arrangement explained it will be seen that the cam Q need be but comparatively short to elevate the de-' livery-arm and also that the coin drops below immediately the cam is depressed.

The hook IV, with the cam Q on the end thereof, is of such shape and comes in such relation to the coin holder V (which coinholder V is rigidly attached to the frame of the machine) that the proper coin will rest on the edge of the cam, as shown in Fig. 3, so that when the carriage is pushed forward the cam will be operated on by the coin, pushed down, and the bell-crank lever turned so that the pin 1 thereon will pass above the elevated rest or ratchet bar R and catch in the first ratchet before the coin is released, as shown in Fig. 4. As the carriage travels farther forward and before the pin 1 has passed entirely over the ratchet-bar the cam Q passes from beneath the coin and allows it to drop into the coinreceiver. As the bell-crank is thus turned, so as to bring the pin 1 above the ratchet-bar, the end of the delivery-arm N comes in contact with the lowest package inthe stack of packages and pushes it from its position, as shown in Fig. 5, allowing it to fall on the slide II, and thus come to the opening G. The pin 1, having passed over the entire length of the ratchet-bar, drops to the combined stop and guide Y under the impulse of the retracting-spring P, and on the removal of the finger from the push-rod the carriage returns to its normal position, the pin 1 passing under the ratchet-bar and the end of the deliveryarm N passing beneath and out of contact with the lowest package in the stack.

Ilaving now sufficiently described the operation of the reciprocating carriage and delivery-arm, I will proceed to describe the coinconducting device.

The carriage being in its normal position, as shown in Figs. 1, 3, and 8, the coin may be inserted in the slot and will fall on the coinslide U beneath the same and pass over that across the ends'of the magnet T, rigidly attached to the frame of the machine, and, ifa non-magnetic coin, will go into the coin-guide M, which is rigidly attached to the reciprocating carriage, and pass from that into the coin-holder V and rest at its lower edge on the cam Q, as shown in Figs. 1 and 3, being in a position to operate the; crank-lever when the carriage is pushed, pressing the cam down and lifting up the delivery-arm, so that the pin 1 comes on the ratchet-bar and the end of the delivery-arm N in contact with the lowest package in the stack. If, however, the coin is thinner than the predetermined coin for operating the machine, it will pass down beyond the cam and drop out of the coinholder, so that the machine will be inoperative in the delivery of a package, and if, again, an iron washer or magnetic metal slug is inserted, instead of a proper coin, in the slot it will fall upon the slide U and, passing over the magnet T, will be held by the magnetism on the end of the magnet, as shown in Fig. 8. Then when the carriage ispushed in, the upright part S, which carries the slot-closer, which is cut away to allow the magnet to pass through, will push the slug from its position on the end of the magnet, thus acting as the magnet-stripper, as shown in Fig. 9, and allow it to drop in the coin-receiver without operating the machine for the delivery of a package.

As it frequently happens that pasteboard or paper slugs of the size and thickness of a coin are used to operate vending-machines, I

have arranged the camQ and the retractingspring Pof such shape and strength that the edge of the paper will be bent by the cam instead of the cam being operated by the paper or pasteboard, and as it-sometimes happens that thin pieces of metal or cardboard of irregular size are used to operate the vendingmachines, which may become clogged in the coin-guide M, I have provided a slot in the front and back thereof, and-a pin X, rigidly attached to the frame of the-machine, so that when the carriage is pushed in the pin X will enter and pass through the coin-guide and the coin, pasteboard, or other contents of the coin-guide will be pushed out by the pin, thus clearing it from all obstructions.

The coin-holder V is rigidly attached to the frame of the machine and is of the proper size to receive a predetermined coin on its.

edge, as shown in Figs. 1, 3, and at, the predetermined coin falling on the cam Q is prevented from going farther, and as the carriage is pushed in the cam, pressing against the edge of the coin, looks it in the coin- .holder, and the bottom ofv the coin-guide M passing over the top of the coin prevents it from being pushed out by the cam, so that it is rigidly held in its position while it operates upon the cam Q to turn the crank-lever.

It is manifest that after the carriage has been pushed forward far enough for the pin 1 to engage with one notch of the ratchet-bar B it cannot be withdrawn, but must be pushed in until the pin passes over the end of the ratchet-bar.

The operation of this machine is as follows: The machine being in the position shown in Figs. 1, 3, and 8, the coin-slot F opens, a predetermined coin is dropped in, which falls moving the carriage L forward, carrying with it the slot-closer K, so as to close the slot F and prevent the introduction of another coin, I

pressing the cam Q against the coin, thereby raising the delivery-arm N of the crank-lever, so that the pin 1 thereon comes in cont-act with the upper edge of the elevated rest or ratchet bar R, the cam Q passing from beneath the coin, allowing it to fall in the coin-receiver. On the continuous forward progress of the carriage the delivery-arm N'pushes out the lowest packageof the stackof packages, and the pin 1, passing over the end of the ratchetbar R, falls upon the combined stop and guide Y beneath the same. On the removal of the finger from the push-rod I the retractingspring P, acting on the hook-shaped arm W,

mechanisms and that one spring only is necessary to accomplish all of the results that are usually obtained by the use of several in mechanisms of this character.
