2 Claims.

to provide a runway or chute through which the coin will pass before it is deposited into the mechanism which it is to render active.

It is one of the objects of the present invention to provide improved means, preferably in proximity to the entrance opening of the chute, for separating or detecting the coins or tokens that are deposited therein so that improper ones will be arrested and prevented from traveling through the runway, but which arresting means will not interfere with the passage of proper coins or tokens through the chute.

A further object is to provide improved means for retaining the improper coin or token in proximity to the entrance opening of the chute, and improved means whereby the coins or tokens thus retained may be engaged by an implement and passed back through the receiving opening, to be returned to the operator.

To the attainment of these ends and the accomplishment of other new and useful objects 1- as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed, and shown in the accompanying drawing illustrating this invention, and in which:

Figure 1 is a detail view in elevation of the en trance portion of the coin slot or chute.

Figure 2 is a detail sectional view taken on line 2-2 Figure 1.

Figure 3 is a detail perspective view, partly in section, of a portion of the coin chute.

Figure 4 is an enlarged detail sectional view taken on line 4-4 Figure 11 Figure 5 is an enlarged sectional view taken if:

on line 55 Figure 4.

Figure 6 is a view partly in elevation, partly in section, and partly broken away, of another form of coin chute.

Referring more particularly to the drawing, the so numeral I0 designates generally a runway or chute along which the coins are adapted to travel, the runway being provided with a bottom H.

A magnet I! (Fig. 2') is arranged adjacent one of the sides of the runway to create a magnetic field through which field the coin or token I3 is to pass as it passes down the runway, the pole or free ends of the magnet passing through suitable openings of the wall of the runway.

This runway is preferably arranged in an inclined position and is provided with an entrance opening [4 and arranged in alinement with this opening is a coin receiving slot l5 which has communication with said entrance. The entrance slot i4 is preferably arranged in an inclined position although if desired it may be arranged uprightly. A magnet I6 is held in position in any suitable manner such as by means of a band or strap I! anchored at its ends, as at IS.

The poles or free ends I 9 of the magnet project through suitable openings in the wall of the entrance slot I4 and this slot 14 is provided at its bottom with a shoulder 20 having an inclined or beveled portion 2|, so that when the coin l3 which is of a proper denomination and characteristic is inserted in the slot l5 it will strike and be deflected by the inclined portion 2| into the entrance opening M of the chute or runway.

When, however, a token or slug 22, which is of an improper value or characteristic, is deposited into the slot I5, if such slug is of a metallic construction, it will be attracted by the poles or ends l9 of the magnet so that the periphery of the slug will engage and rest upon the shoulder 20 and the slug will thereby be prevented from passing into the entrance opening M of the runway and will be maintained in this position.

In these circumstances, should it be attempted to dislodge the slug 22 from the magnet M5 by the insertion of other tokens or by an implement inserted into the slot I5 in an attempt to force the slug 22 downwardly into the runway H), the shoulder 20 upon which the slug rests will prevent such operation, due to the fact that the magnet #6 will hold the slug in a position that it will rest upon the shoulder 20.

In the event that such a slug is inserted into the slot I 5, and in order to remove the same, there is provided a slot 23 in the casing wall 24, a portion of which slot is in alinement with a slot 25 that passes through the shoulder 20 and also the inclined portion 2| thereof.

With this arrangement when the slug 22 is held adjacent the magnet 16 an implement may be inserted through the slot 23 below the slot 25 in the shoulder 20, and then by raising the implement so as to move the same toward the other end of the slot 23, the end of the implement will pass through the slot 25 and engage the edge of the slug 22 and raise the latter, forcing the same along the magnet l6 so as to project the slug a sufiicient distance beyond the entrance of the walls of the passage which permits the Y insertion of an implement to remove the coin 28 which has adhered to the magnet IE, or which is held within the slot, conforms to the configuration of the passage 26, a portion of the slot 2'! being in register with the slot 25 through the 5 shoulder 20 so as to permit the implement to be inserted beneath the lowermost edge of the coin or token. By then manipulating the implement to raise the coin and pass it back through the passage 26 it will be returned to the operator.

been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.

What is claimed as new is:

1. Detecting mechanism for coin and like meelement through the passage, a portion of the said shoulder being beveled to deflect predetermined elements past said shoulder and into the passage, and a permanently stationary magnet in proximity to said shoulder and operating to hold other predetermined elements in alinement with said shoulder, whereby upon insertion of another coin into said passage, the coin held by the magnetic means will be caused to abut said shoulder, there being a slot in a wall of said mechanism and an opening through said shoulder and through which slot and opening an implement may be inserted to engage and force out of the entrance of said passage, the said ele ment which has been retained in engagement with said shoulder.

2. Detecting mechanism for coins and like metallic 'disc shaped elements embodying an element receiving passage of substantial length, a shoulder formed in said passage in the path of movement of an element through the passage, a portion of the said shoulder being beveled to deflect predetermined elements past said shoulder and into the passage, and a permanently fixed and stationary magnet in proximity to said While the preferred form of the invention has shoulder and operating to hold other predetermined elements in alinement with said shoulder, whereby upon insertion of another coin into said passage the coin held by the magnet will be moved against said shoulder and maintained tallic disc shaped elements, embodying an element receiving passage of substantial length, a portion of one of the walls being shaped to form a shoulder in the path of movement of the said against further advancement in said passage, there being a slot in a wall of the passage, and an opening through said shoulder and said beveled portion for the passage of an implement to engage under the edge of the coin to move the latter backwardly in said passage.
