JOSEPH GRICE, or SUTTON-COLDFIELD, ENGLAND.

COlN-OPERATED VENDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 655,437, dated August 7, 1900.

Application filed February 24:, 1900. Serial No. 6,331. (No model.)

To all whom, it may concern.-

Be it known that I, JOSEPH Green, a subject of the Queen of GreatBrit-ain and Ireland, and a resident of 38 Parade, Sutton-Coldfield, in the county of \Varwick, England, have invented certain new and useful Improvements Relating to Coin Operated Vending Machines, (for which I have filed an application in Great-Britain, No. 15,806, hearing date August 2, 1899,) of which the following is a specification.

This invention consists of improvements relating to coin-operated vending-machines, my object being to prevent the freeing of the retaining mechanism by iron or steel disks or blanks and the blocking of the machine by such and other disks or blanks or by distorted coins or coins of light weight or of another value than that for which the mechanism is adjusted.

My invention comprises the arrangement, in combination with the coin-admission slot and channel or chute and the coin-weighing device, of a magnet or magnets for arresting iron and steel blanks and disks and of simple and convenient means for effecting the return through the slot or admission-aperture of the machine of anything inserted therein that will not free the retaining mechanism or a coin of the wrong value that may have been inserted in error.

Referring to the three accompanying sheets of explanatory drawings, Figure 1 is a front elevation, with part in section, representing the application of my invention to a vending-machine of the ordinary sliding-drawer type. Fig. 2 is a sectional side elevation through the line a b, Fig. 1; and Fig. 3, a sectional plan through the line a d, Fig. 1.

The same reference-letters in the different views indicate the same parts.

A is the drawer or pull-piece, which slides in the frame B, arranged in the ordinary manner within or upon the outer casing of the machine, of which 0 is a portion. Upon the underframe A, forming a part of and moving with the drawer or pull-piece A, is mounted the pintle D, having affixed to its center the arm or lever E and to'one end of the double pawl F, engaging with the racks G G, as shown, one of such racks preventing the forward motion of the drawer or pull-piece A, (until the pawl is raised,) while the other prevents the return of the said pull-piece before its forward movement is completed.

On the insertion of the proper coin through the slot or admission-aperture at Z) it falls through the channel or chute formed by the slotted bars H H (secured to the under side of the frame B) until it is brought to rest upon the parts 010. of the underframe A. In such a position the coin forms an abutment for the arm or lever E, so that when the drawer A is pulled after the insertion of the coin the abutment of the said lever against the coin causes a sufficient rotation of the pintle D (against the tension of the spring J, connected with one end of it) to lift the pawl F clear of the lower rack G, and so permit of the complete forward movement of the drawer.

The aforesaid mechanism constitutes no part of my invention and is referred to only that such invention, which is hereinafter described, may be the more readily understood.

On the inner side of the frame B and be tween the slotted bars H H, forming the coin channel or chute, I mount one or more magnets K, the poles of which are placed adja-' cent to the said coin channel or chute, so that if an iron or magnetic blank or disk be inserted through the slot I) such blank or disk is held or retained by the magnet and prevented from falling in front of the arm or lever E, hereinbefore referred to. The magnet is omitted in Fig. 3 in order that the parts beneath it may be clearly shown.

Beneath the magnet I arrange the coinweighing device, consisting of a properly weighted lever L, mounted upon a projection M from the underframe A. A portion of such lever projects at right angles to its main part across the front of the coin channel or chute, and pegs, as L L from such portion project across the channel or chute, as shown. As the proper coin descends through the chute it will on coming into contact with the pegs L L overbalauce the lever L, and thus fall to its position in front of the arm or lever E; but should a light blank or disk or a coin of light weight be used the arm or lever will not be overbalanced, and thus the blank will be retained in the slot above the arm or lever.

For effecting the return through the slot of an iron or magnetic blank or disk or of a light coin or other article retained in the coin channel or chute and which if not removed therefrom would block the working of the machine I provide a returning device, as hereinafter described.

Upon a suitable part of the external casing 0, I pivot a lever N, having its outer end formed as a handle and its inner end connected to a push-piece 0, arranged to slide vertically in guides P on the operation of the lever N, the movement of the said lever imparting the required reciprocating motion to the push-piece. The upper end of the pushpiece 0 is preferably made of a forked shape, and when the complete push-piece is raised by the depression of the handle end of the lever N the forks of 0 will pass between the aforesaid pegs L L on ascending through the coin channel or chute. The push-piece is made to ascend to the top or nearly to the top of the coin channel or chute in order that it shall push out through the slot the blank or other obstruction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A blank-returning device for coin-operated vending-machines comprising a chute extending from the inlet into the machine, and a push-piece with means for operating the same along the chute in'a direction opposite to the entering movement of the coin so that the spurious coins may be ejected through the inlet-opening, substantially as described.

2. A returning device for coin-operated vending-machines consisting of a push-piece which is free to slide within the coinchute and a push-piece-operating lever having its handle end projecting beyond the exterior of the casing of the machine, substantially as described.

3. In coin-operated vending-machines, the combination with the slotted bars H H forming the coin chute and the balance-lever L mounted on the underframeA' of the sliding drawer A, of a push-piece 0, guides P, and push-piece-operating lever N, substantially as set forth.

4. In coin-operated vending-machines, the combination with the slotted bars H H forming the coin-chute and the magnets K secured to the under side of the fixed frame B, of a push-piece 0, guides P, and push-pieceoperating lever N, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of two Witnesses.

JOSEPH GRIOE.
