PATENT 0F NEW YORK, N. Y.

SPECIFICATION forming part' of Lettere Patent No. 611,825, aerea oeteber 4, 1898.

Applieetien feed Mey z5, 1398.;

ToaZZ whom it may concern:

Beit known that I, JOHN H. VoLKMANN,re siding in the city, county, and State of New York, have invented certain new and useful Improvements in Coin-Testers for Coin-Controlled Apparatus, of which the following' is a specification.

My invention relates to coin-testers for coincontrolled apparatus, such as vendingmachines, and the invention is in the nature of an improvement upon the device forming the subjectmatter of my former patent, No.A 483,188, which was issued to me ou the 27th day of September, 1892. Y

The object of my present invention is to render the device of my former patent above referred to and coin-testers generally more efficient and to provide a device which will more effectively prevent telegraphingthat is to say, which will effectively prevent a washer or like false token from being rapidly projected through the tester Without allowing the parts to operate upon the token to prevent it from passing to the delivery mechanism.

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

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a side view of a coin-tester embodying my invention. Fig. 2 is a like View of the same looking from the opposite side. Fig. 3 is a transverse vertical sectional view of the same on the line 3 3 of Fig.. 2 looking in the direction of the arrow. In this iigure the parts are shown in the normal position. Fi g.` 4 is a View corresponding to Fig.,3, except that the parts are shown in the position 'in which the washer or false token is discharged from the device. Fig. 5 is a front View of the device with the parts shown in dotted lines to the rear of the slot-plate or the plate which is provided with the coin-receiving openings.

It should first be pointed out that the cointester herein shown 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 delivery mechanism must pass through the coin-tester. It is' immaterial for the purposes of my invention what Serial No. 681,6 5 5. (No model.)

character of delivery or operating mechanism isv used, inasmuch as the coin-tester may be employed with any character of coin-controlled apparatus, and hence I have shown no delivery or operating mechanism.

In the drawings, A represents the framing, which supports one or more coin-testers in an inclined position in the machine, as indicated in the drawings, and I prefer to make the slots or coin-receiving openings c of each of these coin-testers in the front plate b of this framing. To this framing is secured a stationary plate B,which is provided at its lower edge with a coin-track c, that is cutaway or recessed for a portion of its length, as indicated at d, for the purpose of allowing a coin or token of less thickness than that intended to operate the apparatus to pass through the recess to a point where the token is ineffective to operate the delivery mechanism. A movable plate C is pivoted to the stationary plate by a pivot-pin c or otherwise. The movable plate C is normally maintained in contact with the track c, as illustrated in Figs.

3 and. 5, by a spring f, which is shown to pass around the pivot c, and one end of said 'spring bears against the upper edge of the movable plate, while theV other end rests against a stationary portion of thestructure. The movable plate C is provided with an elongated perforation, as indicated at g, for the purpose of allowing a coin of smaller diameter than lthat intended to` operate the device to drop o the track to one side and to a point where it is ineffective to operate the delivery mechanism. The movable plate C is likewise provided with a finger 0c, which is located adjacent to the front plate b and projects across the slot at the upper portion thereof, as clearly l indicated in Fig. 5, so that when a coin of the requisite diameter is inserted in the slot the coin will contact with the finger and will force the movable plate O around its pivot into the position indicated in Fig. 4. This separation of the platesB and C allows any false coin or token which may have been prevented passing through` the tester to be discharged into a suitable receptacle, where it is ineffective to operate the .delivery-machine. To one of the plates B C (to the plate B in the present instance) a magnet D is secured by means of a support F, which is pivoted in any IOO suitable manner, as indicated at h, and is maintained in the normal position represented in Fig. 3 by a spring y. A link connection t' unites the pivoted supportF of the magnet with the opposite plate, so that a movement of the plates away from each other will cause the magnet to be moved around its pivot, so as to convey the poles of the magnet out of the path of the coin or from their position adjacent to the coin-passage.

Pivoted to the pin e is a washer-catcher E, which in the present instance is normally maintained in the position illustrated in Fig. 3 by its own weight. It will be observed that the washer-catcher extends to the rear of the magnet D and in the path of the movement thereof, so that when the magnet is vibrated from the position shown in Fig. 3 to that illustrated in Fig. 4 it will contact with said washer-catcher and positively move it to one side for purposes which will hereinafter appear. When the washer-catcher is in the position illustrated in Fig. 3, the free hooked ends k Z thereof project across the path of the coin in its passage through the tester. These hooks 7i; Z project toward each other, so that a coin such as is intended to be used in the instrument will force the washer-catcher out of its path and the coin is free to pass to the delivery mechanism. It', however, a Washer of the thickness and diameter of the coin intended to be used is inserted in the slot, it will be caught upon a hook 7c and will be prevented from passing through the tester. When the next coin or token is inserted in the slot d, the plates B C will be separated in the manner hereinbefore described,which will result in the magnet being vibrated on its pivot, thereby moving the washer-catcher to the position indicated in Fig. 4, which causes the hook-like projection 7c to be withdrawn from the perforation in the washer, and the plates being separated. at this instant the washer is allowed to drop from between them.

It has been found in practice that when a washer is projected with some force through the coin-tester the gravity washer-catcher will be vibrated to its fullest limit out of the path of the washer and that it does not always drop back into position in time to allow the hook 7c to enter the perforation in the washer and prevent it from passing to the delivery mechanism. The principal object of the present invention is to prevent a washer from being projected rapidly through the device to operate the delivery mechanism. For this purpose I provide an abutment m, which is adapted to be moved by the operation of the movable plate C. In the present instance this abutment m is in the nature of a nger which projects from the vibratory magnetsupport F and in the normal position extends back of the washer-catcher, as indicated in Fig. 3, and is just far enough away from the catcher to allow it to clear itself from the path of the coin. Vhen, however, the plates B C are separated by the insertion of a coin,

the stop m is automatically moved out of the path of the Washer-catcher to allow a full and free movement thereof, as indicated in Fig. 4. By this means it will be understood that should an attempt be made to telegraph the device the washer-catcher, after it has moved sufficiently far to clear the first hook l, will strike against the abutment m, and the catcher will immediately be in a position where the hook 7c thereof will drop into the central opening in the washer and prevent a further movement thereof along the chute formed by the plates B C. The more rapidly the washer is projected through the tester the more rapidly will the washer-catcher return to the engaging position because of the fact that it strikes with greater force against the abutment m.

From the foregoing description it is thought that the operation of the apparatus will be understood and that no further description of the operation is required.

In practice my improvements have proven simple, cheap, and eflicient means for overcoming the difficulties hereinbefore pointed out.

While I have shown and described my improvements in a coin-testing device embracing features which are disclosed in patents heretofore granted me, I would have it un derstood that the device forming the subjectmatter of my present invention may be employed in any coin-testing apparatus where it may be found available.

lVhat I claim, and desire to secure by Letters Patent, is-

l. In a coin-tester, the combination of a vibratory washer-catcher normally projecting across the path of the coin and an abutment against which said washer-catcher is adapted to be forced by the coin in its passage through the tester.
