AUTOMATIC VENDING-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 430,499, dated June 17, 1890.

Application filed December 4, 1889. Serial No. 832,523. (No model.)

To all whom it may concern: rod or shaft c, which latter is in turn sup- Be it known that I, JOHN A. WILLIAMS, a ported by arms d d, projecting from the rearcitizen of the United States, residing at Brookface of the upturned end of the deliverylyn, in the county of Kings and State of New slide, the plate with its rod or shaft moving 55 5 York, have invented certain new and useful relatively to the arms d d, as indicated in Improvements in Automatic Vending- Ma- Fig. 4.

The Operating mechanism is cludes any effacement of the books or other similar to that shown in my patent, No. articles, and also prevents it from catching 414,7 86, issued November l2, lSSQthat is to onto them and thereby interfering with the say, it comprises a flat plate B, an operatingoperation of the machine.

outlet f, aids in protectin gfthe machine again st surreptitious withdrawal of the articles.

Pivoted to the inner face of one of the guide-walls K for' the slides is a pawl or dog L, which, as shown in Figs. l, 2, and 3, comprises a toothed or roughened portion t' and a tail j, the tail of the pawl or dog being heavier than the head or toot-hed portion and tending to keep the latter up in engagement with a toothed portion k of the actuating-slide.

Secured to the delivery-slide near its forward end is a lug Z, which, when the slide is in its normal position, bears against or under the heel of the pawl or dog L and keeps its toothed portion away from the under face of the actuating-slide, while near the rear end of the delivery-slide is lug m, which, when the said slide is pulled outward far enough to eject a book, rides under the tail of the dog, rocking the same and throwing the toothed portion out of engagement with the actuating-slide. When the delivery is moved so far as to bring its lug m under the tail of the dog L, it will be found to be in such position as to be engaged by the pawl or dog E, as shown in Fig. 3, the said slide being held in thisA position by the dog E, as clearly shown in my patent, No. 414,786, before referred to. Now when the operator releases his hold of the actuating-slide the latters spring draws it inward, and as it moves inward it strikes the upper end of the pawl E, rocking the latter and permitting the delivery-slide to be also drawn inward. The return or inward movement of the actuating-slide is sudden, so that by the time it strikes the pawl E and releases the delivery-slide D the pawl L may assume its normal position, the said actuating-slide C will be found to be at the limit of its inward movement and in its normal position.

When a coin of the requisite size is placed in the machine, it will be supported at its lower sides by the blocks I and at the upper edge by the walls of the coin-slot in the actuating-slide C and a lug in rear of the coin, the lower edge of the coin being in such position as to engage a lug on the delivery-slide Now when the opertor pulls the slide C outward the coin carried thereby will strike the lug on the deliveryslide D and lock it to the actuating-slide C, so that the two slides will move together as the slide is pulled outward. As the deliveryslide D is thus moved outward by the actuating-slide, the lug Z is carried from beneath the pawl L, and the head or toothed portion of the latter allowed to come into contact with the under face of the slide C; but owing to the inclination of the teeth on the slide and the pawl and the curvature of the face of the head of the pawl the slide C will ride freely over the pawl without engaging therewith. Should it happen that the operator releases the actuating or operating slide C before it has been pulled outward far enough to cause the delivery-slide D to eject the article the spring F will tend to return the actuating-slide C to its normal position within the machine; and it will be seen that if this were permitted the two slides would be disconnected and the coin permitted to fall into the money-box without making any adequate return for the money. It is to prevent this that the pawl L is used. it being clear that as soon as the slides C and D begin to move cinward the slide C will be arrested in its movement by the toothed face of the pawl, the teeth of the latter engaging the teeth or notches in the under face of the slide C, and thereby preventing the dislodgment of the coin and further inward movement of the slides. lVhen the slide C is pulled outward far enough to eject the article, the stud m on the slide D will be brought under the tail of the dog L,while the dog E will engage the slide D and hold the latter in its extended position. If the slideC be now released, its spring will draw it inward and cause the said slide to strike the pawl E, thereby releasing the slide D and withdrawing the stud m from under the dog L, as before explained.

Instead of constructing the pawl L as shown in Figs. l, 2, and 3, it may be made as illustrated in Figs. 6 and 7, upon reference to which it will be seen that the pawl has its upper end pointed to engage and hold the actuating-slide, while its lower end projects downward through a slot in the delivery-slide. When the parts are in their normal position, as represented in Fig. 6, the pointed upper end of the pawl willbe found resting in a depression n in the slide C; but should the slide C be only patrially withdrawn the upper end of the pawl will engage the teeth 7o on the slide C and hold the said slide, together with the slide D and the coin, against inward movement, essentially in the same manner as the pawl L. (Illustrated in Figs. l, 2, and When the slide C has been pulled outward far enough to cause the slide D to eject the article or package, the said slide C will be found to have moved from over the upper end of the pawl, as shown in Fig. 7, so that when said slide is released it will strike and ride over the upper end of the pawl, rocking the latter, as indicated by dotted lines in said figure.

A locking device for holding the slide C extended in the mannerset forth herein, is not broadly claimed in this application, but is claimed, broadly, in other applications filed by me, Serial Nos. 332,521 and 352,882.

Having thus described my invention, what I claim is l. In a vending-machine, the combination, with a plate or support II, adapted to receive the books or other articles and provided with an opening a, of a delivery-slide D, provided with arms (l d, and a pivoted ejector plate J, journaled in the arms d d and working in the opening a, all substantially as shown.
