SPECIFICATION forming part of Letters Patent N 0. 598,545, dated February 8 1898. Application filed November 8,1897. fierial No. 657,729. (No model.)

To aZZ whom, it may concern.-

Be it known that I, JOHN H. VOLKMANN, a subject of the Emperor of Germany, residing in the city, county, and State of New York, have invented certain Improvements in (loin- Testers for Coin-Controlled Apparatus, of which the following is a specification.

My invention relates to coin-testers for coincontrolled apparatus, such as vending-machines; and the invention is in the nature of an improvement upon the device forming the subject-matter of my former patent, No. 483,188, which was issued to me on the 27th day of September, 1892.

The object of my present invention is to render more effective the device of my former patent above referred to, and to provide a device which will reject or prevent all manner of coins or tokens except those embodying all of the characteristics of the coin intended to be used from operating the delivering or operating mechanism.

To this end my invention consists ,in the novel arrangement and combination ofparts hereinafter described and claimed.

the false coin released from the magnet on the introduction of the next succeeding coin.

Reference is first had to the device illustrated in Figs. 1 to 5, inclusive, which represent the preferred form of coin-tester embody- W'hile Figs. 1 and 2 represent the coin-tester as standing in a horizontal position, it should be understood that in use the coin-tester assumes an inclined position, as indicated in Figs. 7, 8, and 9, for conveying the coin therethrough.

It should first be pointed out that the cointester of my invention constitutes, in a sense, a portion of a coin-chute, so that the coin in its passage from the coin-inlet or slot-opening of the apparatus to the delivering mechanism must pass through the coin-tester. I

It is immaterial forthe purposes of my in vention what character of delivery or operating mechanism is used, inasmuch as the coin-tester may be employed with any character of coin-controlled apparatus, and hence I have shown no delivering or operating mechanism.

In Figs. 1 to 5 of the drawings, A repre sents a stationary plate, which is connected with the instrument in any suitable manner. This plate A is provided at its lower edge with a coin-track ac, which is cut away or re cessed for a portion of its length, as indicated at y, for the purpose of allowing a coin of less thickness than that required to operate the apparatus to pass through therecess formed in the track. The movable plate B is pivoted to the stationary plate by a pivotpin a or otherwise. The movable plate B is normally maintained in contact with the track of the plate A bya spring Z), which passes around the pivot a and bears against the upper edge of the movable plate. The plate B is provided with an elongated'perfd ration, as indicated at c, for purposes which willhereinafter appear. To one of the plates A B (to the plate A in the present instance) a magnet O is pivoted,as indicated at d. In the present instance I have illustrated this magnet as being carried by a frame e ,wl1ich is pivoted to the stationary plate A. The magnet is connected with the opposite plate from that which carries it by a suitable connection f, so that a movement of the plates away from each other will cause the magnet being pivoted to the pin a.

' to be moved around its pivot. In the present instance the connection fis shown to comprise a link f, which is hooked into the plate 13 and passes at its free end through an aperture in the frame 2 of the magnet. The free end of this link is bent at right angles to the length of the link, (see Fig. 2,) so as to allow of a free movement of the link in the slot until the bend in the end of the link contacts with the frame 6, for purposes which will hereinafter appear. The effect of the movement of the movable plate is to move the magnet or the poles of the magnet away from the plate through which it projects and out of the path of the coin. In the present instance the stationary plate has been recessed to enable the magnet'or the poles of the magnetto be projected through it. This magnet O is normally maintained in the position near the path of the coin, as illustrated in Fig. 3, by a coiled spring g or by other suitable means. The movable plate may, if desired, be provided with one or more arms D, which are adapted to pass through the stationary plate and to be moved across the path of the coin in its passage through the coin-tester when the movable plate is moved away from the stationary plate with which it cooperates. A finger h is carried by the movable plate and normally projects across a portion of the coin-inlet opening in the face-plate or slotplate E on the instrument. The projection i may likewise extend from the stationary plate to guide the coin in its passage from the coin-inlet to the coin-tester. It may also be found desirable to providethe tester with a hinged washer-catcher F, which is shown as In my preferred construction this washer-catcher is located in the path of movement of the magnet around its pivot, so that when the plates are separated by the introduction of a coin the magnet will be moved into contact with the washer-catcher and move it out of the path of the coin, (see Fig. 4,) thereby withdrawing the arm of the washer-catcher from the perforation of the washer if one has caught, thus allowing the washer to drop from between the plates A B.

As before stated, the coin-tester is mounted in the device in an inclined position, as represented in Fig. 7, and is likewise maintained in a position inclined to one side, as represented in Figs. 5 and 6.

Upon the introduction of a coin into the device illustrated in Figs. 1- to 5, inclusive, the coin will first contact with the finger h and will move the movable plate to one side away from the stationary plate, as represented in Fig. 4. As soon as the coin has passed the finger h the tension of the spring I) will cause the movable plate B to resume its normal position. (Illustrated in Fig.3.) If now the coin be a proper one, it will pass along the rail :20 between the plates A and B and will be conveyed to the delivering mechanism to cooperate therewith to deliver the package or to set the instrument in operation, as the case may be. If, however, the coin be of insufficient thickness, it will pass through the recess y in the track so and will not be delivered to the delivering mechanism. If the coin be of insuflicient diameter, it will passthrough the perforation c in the plate B. If

a washer of the same diameter and the same thickness of the coin intended to operate the device be introduced into the tester, it will be caught by the washer-catcher F, by reason of the fact that this catcher normally proj ects across the path of the coin and is forced to one side by the proper coin, and if there is a central perforation in the token introduced into the instrument the second projecting arm of the washer-catcher will pass into the perforation and prevent the washer or other perforated disk from passing through the coin-tester, as is illustrated in Fig. 8. The introduction of a proper coin will cause the Washer-catcher to be positively shifted to one side in the manner hereinbefore described. It will likewise be observed that this introduction of a proper coin will cause said coin to contact with the first arm of the washercatcher and will provide an additional means for releasing a washer which has been retained by the second arm by forcing the washer-catcher to one side and consequently withdrawing the second arm of the catcher from the perforation in the washer. If a magnetic disk or washer be introduced into the coin-tester, it will be held by the magnet O and be prevented from passing beyond that point. The introduction of the next coin will contact with the finger h, separate the plates in the manner which has been hereinbefore described, thereby causing the magnet to be withdrawn from its position adjacent to the coin. This will effect the release of the magnetic disk or washer held by the magnet, since the side wall of the stationary plate will prevent the disk or washer from following the magnet. When the disk or washer is released, it will drop from between the plates, as indicated in Fig. 4, and will therefore be ineffective to operate the delivering mechanism.

The purpose of the arms D is to prevent a coin from being forced rapidly through the coin-tester, so that each of the various elements willnot have a chance to perform its respective function, or, in other words, to prevent what is known as telegraphing in instruments of this character. It will be observed that the link which forms the connection between the movable plate and the magnet 0 allows of some play to the movable plate without moving the magnet around its pivot. This is provided so that the movable plate may be operated by the introduction of a coin withouthaving an unnecessary amount of spring-pressure to overcome in the initial step of introducing the coin into the instrument. In this construction the coiled spring g, which maintains the magnet in the normal position, is not moved or a pressure is not nevertheless any such disk or washer which exerted against it until the coin has overcome .the initial resistance of the spring I) while it is being introduced into the coin-slot.

The device illustrated in Figs. 6, 7, S, 9, 10, and 11 is similar in many respects to the device hereinbefore described. The modified form of coin-tester is provided with a stationary plate A and movable plate B. A recessed track a; is provided upon the stationary plate, the movable plate is apertured, as indicated at c, a spring isprovided for normally maintaining the movable plate in contact with the stationary plate, and a magnet O is pivoted to the stationary plate. However, in this construction the magnet is located in a somewhat different manner'from that constituting the preferred form of my invention and the means for operating or withdrawing the magnet are somewhat different. In the modified form an arm j is carried by the movable plate and is shown in the present instance as being made integral therewith. This arm bears upon the frame 6, which carries the magnet, and a movement of the movable plate B around its pivot to will cause the magnet to be moved around its pivot cl, so that the poles of the magnet will be withdrawn from the wall of the stationary plate A, through which they project, and will thereby release the magnetic disk or washer if the same has been caught by the magnet. The movement of the movable plate in this case is effected by the introduction of a coin bearing against the finger h in the manner hereinbefore described with reference to Figs. 1 to 5, inclu sive. The washer-catcher F in this modified construction is operated to release a washer by the introduction of a proper coin in the following manner: The introduction of a proper coin will cause the plates to be separated in the manner hereinbefore described, which will cause the washer-catcher which is pivoted to the movable plate to be slightly elevated. The elevationof the catcher will bring it into contact with the cam 2 on the stationary plate, which cam will cause the catcher to be shifted to one side, thereby withdrawing the arms thereof from the washer if one has been caught by the catcher and the washer will drop from between the plates where it is ineffective to operate the delivery mechanism.

Heretofore coin-controlled apparatus have been devised wherein stripper arms or fingers were provided to strip the false coin from the magnet, but there were disadvantages presented in such devices which rendered them unreliable and uucertain-as, for instance, the stripper-finger was liable to be projected through the central aperture of the washer held by the magnet and fail to strip the said washer from the magnet, thereby rendering the device inoperative. It will be observed that by my invention no stripper arms or fingers are necessary to dislodge a magnetic disk or washer from the magnet, and that is caught by the magnetis effectively stripped from the magnet by the side wall of the plate with which the magnet cooperates.

By my present invention I overcome the disadvantages heretofore found in coin-testers employing magnets and improve the efficiency of the device forming the subject-matter of my former patent above referred to, and provide a coin-tester which will prove efficient under all conditions and circumstances.

It will be observed that by my present invention all manner of false coins are prevented from being conveyed to the delivery mechanism except a token embodying all of the characteristics of the coin intended to be usedthat is to say, in order to operate the device by a false coin it is necessary to use an imperforate disk made of non-magnetic metal and of the exact diameter and thickness of the coin intended to operate the devlce.
