Specification of Letters Patent.

Patented Oct. 1, 1907.

Application filed June 22, 1906. Serial No. 322,904.

To all whom it may concern:

Be it known that I, MoReAN D. SADTLER, a citizen of the United States of America, and a resident of Baltimore city and State of Maryland, have invented certain new and useful Improvements in Coin-Testing Machines, of which the following is a specification.

My invention relates to certain new and useful improvements in coin testers adapted to be used in connection with coin controlled machines of all types.

The object of my invention is to provide a mechanism which will test each coin dropped into the machine and if it is attempted to operate the machine by what is commonly called a slug, the mechanism will throw out the slug, though it is of the proper size, diameter, thickness and weight.

My invention tests each coin presented to the machine and unless the coin is of the proper size, diameter, thickness and made of the proper metal, the tester will not pass the coin in a manner to operate the coin actuating mechanism to which the tester is applied.

In the form of my invention shown, the tester is adapted to test various denominations of coins. It is to be understood, however, that the number of denominations which can be tested may be varied as desired.

Referring to the drawings, wherein I show one embodiment of my invention for the purpose of illustrating the same and wherein the same part is designated by the same reference numeral wherever it occurs, Figure 1 is a perspective view of a coin tester adapted to be applied to any suitable form of coin controlled mechanism, the top of the case being partly broken away. Fig. 2 is a longitudinal section of the case showing the testing mechanism in side elevation. Fig. 3 is an end view showing the case in section and operating parts in elevation and in their normal position. Fig. 4 is a view similar to Fig. 3 showing the parts in the position they occupy at the limit of movement of the mechanism during the testing operation. Fig. 5 is a top plan view partly in section of the device with the cover removed. Fig. 6 is a central longitudinal section of the testing disks, the shaft on which they are mounted being shown in elevation. Fig. 7 is a detail perspective view of a pair of disks removed from the shaft. Fig. 8 is a view similar to Fig. 7 showing the other side of a pair of disks. Fig. 9 is a detail view of the hinged member of the coin guide. Fig. 10 is a detail perspective view of the shaft on which the disks are mounted and connected thereto, the disks not being shown on the shaft.

1 designates a rectangular case provided with a cover 2 having slots 3 formed therein for the insertion of coins.

4-4 designate a pair of side frames which are secured to a base 5, these side frames preferably and as shown,

are provided with means by which the case 1 may be secured thereto to inclose the testing mechanism.

6 designates a shaft journaled in hearings in said frames 4 and provided at the end with a handle 7 which is located outside the casing 1.

8 designatea series of disks mounted on the shaft 6, the disks being secured to the shaft by any suitable means, as for instance, the pins 9.

10 designate a second series of disks which are loosely mounted on the shaft.

11 are spacing sleeves which, preferably and as shown, are formed integral with the disks 8 and hold the disks 1O spaced a proper distance away from the face of the disks 8. Each of these disks 8 and 10 is provided with a slot 12, the slot being formed radially of the disk, the walls of the slot at the bottom 13 and for about half the distance to the face of each disk being parallel, the walls then being beveled outwardly as at 14, whereby a slot of a substantially Y-shaped cross-section is formed, as is best seen in Fig. 7 and 8. The disks are assembled on the shaft so that a fast disk and a loose disk alternate. The hub 11 extends from the side of the disk 8 which is provided with the slot 12. The slot of the loose disk 10 which is separated from the fast disk 8 by spacing sleeve or hub 11, faces the slot in the fast disk whereby the disks form by their slots a pair of jaws adapted to receive a coin, the length of the hubs 11 determine the size of coin which each pair of jaws is adapted to receive.

The pair of jaws are preferably and as shown, assembled on the shaft so that the fast and loose disks of adjacent pairs of jaws are in contact whereby the loose jaws are held from endwise movement on the shaft. On the face of each of the fast jaws opposite that containing the slot, I preferably provide a pin 15 adapted to engage a concentric groove 16 formed in the adjacent face of the loose disk. i

17 is a stop formed in the groove 16 with which the pin 15 is adapted to contact, whereby the disk 10 will be caused to rotate with the fast disk 8 when the pin and stop are in contact. The pin 15 and the stop 17 in the slot 16 are so located with respect to each other that when each of the fixed jaws is in normal position, the loose jaws will be held in their normal position by contact between the pin 15 and the stop 17.

18 is a disk mounted on the end of the shaft adjacent the end loose disk and secured to the shaft by a pin 9 the same as the fast disks 8. The disk 18 is provided with a pin 15 adapted to engage with the stop 17 in the groove 16 of the adjacent loose disk, whereby this loose disk will be caused to turn to its normal position by the pin engaging the stop in the same manner as the other loose disks.

19 are notches cut in the side of each of the loose I periphery of the disks when they are in position.

disks with which the free end of springs 20 are adapted to engage. The springs 20 are secured at their base to the frame 5 and they are so positioned that their free ends will engage the notches in the loose disks to hold the loose disks in their normal position in line with the slots of the fast disks when they are in normal position, as shown in Figs. 5 and 6. These springs also act to produce a sufficient resistance to the rotation of the loose disks as to cause the pairs of disks to bend a coin held between them which is of less hardness than standard, because the loose disks will not be moved unless the coin or token is of the hardness of the standard coin. l

21 is a flanged disk which is secured to one side of the side frames 4 and through which the shaft 6 loosely passes. To the inside of the flange of this disk is secured one end of a clock spring 22, the other end of the clock spring being secured to the shaft 6 whereby the spring will operate to return the parts to their normal position as soon as the handle is released after the operation of the machine.

In order to prevent slugs formed of iron, such as washers and the like, from being fed into the machine, which might operate the machine, if they were of the proper size to accurately fit the slot in a pair of disks and of the proper thickness to be positioned in the slots, due to the fact that they are so hard that they would not be bent under the twisting action of the pair of jaws, I mount a series of magnets 23 ona plate 24 extendingbetween the side frames 4 and over the disks. These magnets 23 are shown as secured to the plate 24 by means of the screw 25, one magnet being arranged over each pair of jaws.

26 is a plate covering all of the magnets except their ends and held in position by means of the screws 25. The magnets are shown as being horse-shoe magnets and the ends of the horse-shoes are so located as to be adjacent the path of the coin from the coin slots 3 to the slots in the disks, as is best shown in Fig. 5. From this, it will be seen that should an iron washer or similar slug be inserted in the machine, it will be stopped by the magnets and held, thus, preventing such slug from entering the machine.

27 designates a frame which extends from one end of the ease to'the other and is located near the top of the case. This frame is provided with coin slots 28 which register with the slots 3 in the top of the case.

29 is a guiding flange which extends downward from the top 2 adjacent the slots 3 on to the top of the frame 27 beside the coin slots 28 whereby a coin dropped in the slots 3 is guided from the slots 28.

30 is a plate which forms a pivoted coin guide, it being pivoted at 31 to the ends of the frame 27 This plate is adapted to guide the coin after it passes through the slots 28 down into the slots of the disks.

32 is a spring one end of which is connected to the guide plate 31 and the other to the side of the casing whereby the plate is held normally in position to guide the coin in its proper path. The lower end of this plate extends down close to the periphery of the disks and, preferably, the coin slots in the disks are of such a depth that a portion of the coins project beyond the It is therefore, necessary to move this plate out of the path of the coins when the disks are rotated to test the same. it is to permit of this movement that the guide is hinged.

33 designates a rod which is formed ot a main portion of suflicient length to ex tend from one end of the shat t 6 to nearly the other and is secured to the shaft out side of the side frames 4. The ends 34 oi the rod 33 are bent inwardly at right angles and preferably and as shown, pass through openings in the shaft and are engaged in position by means of the nuts 35. The ends 34 of the rod are of such a length that its main portion 33 will pass over the tops of the magnets and close thereto in order to knock off the magnets any slugs which may be held thereon, by the magnetic attraction.

3G is a wing cam mounted on the rod 33 at a corner and this wing cam is adapted to engage a projecting end portion 37 of the hinged guide 30. The hinged guide being of sufiicient length to extend outside the side frame and is provided with slots 38 whereby the guide may straddle said side frames. From this. it will be seen that the wing cam 36 will move the guide out of the path of the coin held between the disks in the testing operation and will also move the guide out from in front of the magnets so that the rod 33 can remove a slug held by the magnets.

39 is a chute extending from the casing l and located in such a position as to catch any slug knocked off the magnet or a slug which is bent in the operation of the testing jaws.

' 40 is an arm mounted on the shaft (5 and adapted to contact with the stops ll mounted on the side frame, whereby the revolution of the shaft on the operation of the handle in one direction and spring in another, is limited to a hall revolution. The arm on the shaft is so positioned in relation to the stop that when it is against the lower stop in its normal position and held there against by the spring, the slots in the disks will be direct under the coin slots in the cover so any coin dropped through the slot in the cover will fall into the corresponding slot in the pair of disks.

In the operation of my device, the parts being in their normal position, a token may be dropped through the proper coin slot 3 and will pass down through the corresponding slot 28 and will be guided by the movable guide 30 adjacent to the end of one of the magnets 23. If the token is not composed of iron. it will pass by the magnet without being attracted. it. however. it is of iron, it will be caught by the magnet and held with the upper edge of the token extending above the upper surface of the plate 26. ll", however, the magnets do not stop the token. then it drops down into the slots in the disks 8 and 10. When now. the handle 7 of the shaft is turned, all of the fast disks 8 turn therewith and if the token is of the proper hardness, it will be sul'hcient to cause the loose disk of the pair engaging the token to move with the fast disk against the tension oi the spring 20 and the two disks will be revolved together carrying the token between them. This rotation will continue until the arm 40 engages the upper pin 41 when the parts will be in the position shown in Fig. 4. The striking of the arm 40 against the pin 41 will cause the coin to be released and dropped out of the tester, down into the bottom of the device where it may pass on to any suitable coin controlled mechanism. li, however, the token is not of standard hardof the slots in the disks and the token will fall on to the chute 39 and will be delivered out of the testing machine without the loose disk turning.

The stop 17 in the peripheral slot 16 of the loose disk is so located with respect to the pin 15 on the adjacent fast disk that the fast disk can turn forward without moving the loose disk. If, however, the loose disk is moved by a token of proper hardness, then it will be carried around and the pin 15 and stop 17 will be in such relation that updn the return movement of the shaft, the pin 15 will immediately engage the stop and return the loose disk to its normal position ready to receive the next token. As soon as it has been returned, the end of the spring 20 engaging the notch 19, will hold the same in position to receive the next token.

While I have described what I believe to be the preferred form of my invention, I desire to have it understood that many changes may be made in the form, construction and arrangement of parts, and other elements may be substituted for those here shown and described, for the purpose of carrying out the function of the elements therein shown and described, without departing from the spirit of my invention, and that wherein I use the term means, this term is to be understood as covering all forms of mechanism which are capable of performing the function ascribed to the term in the claims.
