COIN-DETECTOR FOR AUTOMATIC VENDING-MACHINES.

SPECIFICATION formingpart of Letters Patent No. 564,824, dated July 28, 1896. Application filed November 20, 1895. Serial No. 569,500. (No model.)

To all whom it may concern.-

Be-it known that I, ALEXANDER J AEGER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Coin-D etectors for Automatic Vending Machines, of which the following is a full, clear, and exact specification.

My invention relates to a new and useful improvement in coin-detectors for automatic vending-machines, and has for its object to so construct such a device as to render impossible the passage of iron or steel disks to the money-drawer of the vending-machine, even though said disks be of a size which exactly corresponds with the coin intended to be used in operating the mechanism of the machine and, further, to discharge disks that have been detected to one side of the chute and outside of the trough by the insertion of the next coin or disk.

VVit-h these ends in view the invention consists in the details of construction and combination of elements hereinafter set forth, and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertains may understand how to make and use the same, I will describe its construction and operation in detail, referring by number to the accompanying drawings, forming a part of this specification, and in which Figure 1 is a side elevation of my improved mechanism; Fig. 2, a section at the line 00 as of Fig. 1; Fig. 3, a section at the line 3 y of Fig. 1; and Fig. 4, a View similar to Fig. 2, showing the magnet and its attendant parts forced to one side into position assumed when the coin or disk is being inserted through the slot in the escutcheon.

Similar numbers denote like parts in the views of the drawings.

1 is the ordinary escutcheon, which is secured in the usual manner to the vendingmachine, and from this escutcheon leads downward and backward the primary chute 2, which connects with the secondary chute 3, which latter leads to the money-drawer or other suitable receptacle for the coin which is intended to operate the mechanism of the vending-machine.

Pivoted atin suitable bearings connected with the chutes or other parts of the machine is a permanent magnet 5, having one of its members, preferably the positive, extending downward into close proximity to the guideway formed in the primary chute.

6 is a projection extending upward from the bottom of said guideway, so as to arrest and deflect the movement of the coin or disk in its passage down said guideway, whereby as the coin reaches this projection it will be thrown upward, so that its upper edge will pass between the side of the magnet and the wall of the chute in such close proximity to said magnet as to be within the magnetic field thereof, by reason of which, if the disk be of iron or steel, it willbe drawn into contact with said magnet and thereby arrested and prevented from further movement.

'7 is astrip of brass which serves as a shield and is placed immediately beneath the pole of the magnet, so that as the latter is swung sidewise upon its trunnions its magnetic lines will be interrupted by this shield, for the purpose hereinafter set forth.

A U shaped strip 8 is secured, by means of the screw 9, to the magnet or other part movable therewith, and the-lower member of this strip extends along one side of the passage in the chute, in order that the coin will be prevented from jumping out of said passage when coming in contact with and being elevated by the projection 6. Secured to that side of the magnet opposite this strip is a push-off 10, the nose of which is adapted to swing to and fro through the slot 11, formed in the side wall of the primary chute, so that when a disk has 'been detected and arrested by the magnet, and said magnet is swung to one side to the position shown in Fig. 4, this push-off serves to displace the coin sidewise and permit it to drop outside of the primary chute, as will be readily understood; and, as before described, the shield 7 will interrupt the magnetic lines of the magnet when the latter is swung sidewise, thereby releasing the disk and permitting the push-off to project it outside of the chute; or should the disk passed.

I in its upward movement pass above the lower end of the magnetic pole this shield will prevent it from moving with the magnet when the latter is swung sidewise, whereby it will be caused to lose its hold upon the magnet.

12 is an arm which is secured to the magnet and extends forward, terminating in a toe 13, which bears against the lever 14:, which latter is pivoted at 16 to the escutcheon and projects in front of the slot 17, formed in said escutcheon, through which the coins are This lever is so formed that the coin, being forced through the slot, will move it sidewise upon its pivot, and this side movement of the lever will act upon the toe of the arm 12, thereby swinging the magnet and the parts carried therewith sidewise to the position shown in Fig. 4. Thus, if the disk has been caught by the magnet, as before described, this movement, caused by the insertion of a new coin, will project said disk sidewise and permit it to fall downward, as previously set forth. In order that these false coins or disks may not reach the coin-receptacle, I provide a shield 15, so arranged that when a coin or disk falls thereon it will be deflected to one side and slide into a properlyarranged receptacle therefor. The secondary chute is open upon one side, so that its guideway is formed by narrow flanges upon either edge, in order that a coin or disk passing down said guideway will drop out if it be of too small a diameter, and this is facilitated by the setting of said chute upon a slight angle to the perpendicular, as clearly shown in Figs. 2 and at.

The shield 15 is so arranged relative to this secondary chute as to shed false coins, which may drop out of said chute, in order to prevent them from clogging the machine.

To insure the return of the magnet and the parts carried thereby to their normal position, the spring 16 is so arranged as to bear against said magnet, whereby a resiliency is imparted thereto.

Of course it will be understood that genuine coins of the proper size passing through the primary chute will not be affected when cominginto the magnetic field, and will therefore ride over the projection 6 and drop into Having thus fully described my invention, what I claim as new and useful isi 1. A coin-detector for automatic vending machines, consisting of a primary chute and a secondary chute, the bottom of the passageway of the former being provided with a projection, whereby the coin is elevated, a magnet pivoted so as to swing sidewise, and having one of its poles so arranged as to attract an iron or steel disk when elevated as described, whereby said coin is prevented from passing to the secondary chute, substantially as and for the purpose set forth.

2. A coin-detector for vending-machines, consisting of a primary chute and a secondary chute, a magnet pivoted so as to swing sidewise, a projection formed upon the bottom of the primary chute, whereby coins passing down said chute are elevated into proximity to the pole of said magnet, a lever so arranged relativeito the admission-slot as to be swung sidewise when a coin is pushed into the primary chute, and 'means for transmitting a swinging movement from said lever to the magnet, whereby a false coin, detected by the magnet, will be displaced sidewise and prevented from entering the secondary chute.

3. In an automatic vending-machine, a coindetector, consisting of a primary chute and a secondary chute, a magnet pivoted so as to swing sidewise and having one of its poles projecting into close proximity to the passageway in said primary chute, a projection formed upon the bottom of said passage, whereby a coin, passing down said chute, will be elevated within the magnetic field of said magnet, a push-off secured to and swinging with said magnet, a shield for interrupting the action of the magnet upon the false coin, an arm 12, projecting from said magnet, a lever 14, pivoted to the escutcheon of the machine in such relation to the admissionslot as to be deflected sidewis e when the coin is shoved into said slot, said arm and lever being so related as to transmit a swinging movement from the lever to said magnet, for the purpose of displacing a false coin detected by said magnet, sidewise, whereby it will be dropped out of the primary chute and prevented from entering the secondary chute, substantially as and for the purposes set forth.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

ALEXANDER JAEGER.
