Knee, Charlotte, N. C., assignor to Vanak Corporation, Charlotte, N. C., a corporation of North Carolina 1 Application January 14, 1937, Serial No. 120,490

2 Claims.

This invention relates to a coin or check which is adapted to be used in slot machines, check testing apparatus and the like, and more especially to a check which is adapted for use with a mechaz. nism shown and described in my co-pending patent application Serial No. 32,420, filed July 20, 1935, Patent No. 2,073,392 of March 9, 1937.

In many States of the Union there is an existing law which prohibits the use of any check in a slot machine, game board, check testing apparatus and the like, which is of the same diameter -as a genuine coin. Therefore, it is necessary to substitute therefor a coin or check which is of slightly less or slightly larger diameter than that {of a genuine coin. Since the check testing apparatus shown in my said co-pending patent application has means for testing the surface configurations, the thickness, and the diameter of a coin before accepting the same, it is necessary to provide a coin or check which will comply with the tests applied to a coin or slug inserted therein by this apparatus.

As stated in my co-pending patent application, the feelers, which engage the faces of the coin or check for testing the surface configuration are \equally spaced in a circular row so that the ends thereof will engage the surface of the coin or check. If all of the feelers are actuated exactly the same amount as a result of all the points of contact being at the same level on the face of the coin, then the coin will be rejected. In order for ,the coin to be tested as to its surface configuration, some of the feelers will have to be actuated more than the others as a result of the irregularities on the face of the coin. In order to insure that this effect will be produced on the feelers, the coin or check has been designed so that certain feelers will be sure to hit a high spot on the surface of the coin and certain of the feelers will be sure to engage a depression thereby actuating the feelers an unequal amount.

It is therefore, an object of this invention to 7 {provide a circular check for use in a check testing apparatus having a plurality of spaced depressions therein arranged in a circle whose cen- .ter is the center of the circular row of feelers which are adapted to be pressed against said check, the feelers and the depressions being unlike in number to insure that the feelers will be actuated unevenly to cause the check to pass the *surface configuration test.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawing, in which:-

Figure 1 is an isometric view showing one side of the invention;

Figure 2 is an isometric view showing the opposite side of the invention from that shown in Figure 1; V

Figure 3 is a sectionalview taken along line .3-3 in Figure 2;

Figure 4 is an elevation of a check similar to that shown in Figures 1, 2 and 3, but having the depressions on opposed sides thereof in a stagered relation to each other; v

Figure5 is an elevation of a slightly different 'modified form of the invention constructed along the same lines as that shown in Figure 4;

Figure 6 is a sectional view taken along line 6-43 in Figure 5.

Referring more specifically to the drawing, the numeral l0 denotes a suitable coin or check which is adapted to be used in a slot machine, check testing apparatus and the like, said coin having a plurality of evenly spaced depressions I I on the face thereof and a plurality of similarly arranged depressions I2 are disposed exactly opposite each other on the faces of the coin, thereby providing ridges or high places l3 and I4 between these cavities. These high places or ridges l3 and I4 are substantially at the same elevation or level as the other surfaces of the coin. The feelers in my co-pending application, Serial No. 32,420, are evenly numbered and evenly spaced, there being ten feelers concentrically spaced. The coin I0 is placed in the apparatus with the central portion thereof placed in coinciding relation with the center of the circular row of feelers.

It will be noted that in the coin l0 there are nine evenly spaced concentric cavities II and 'nine cavities 12. When the coin is placed in testing position in the apparatus and the testing means or feelers are thrown into operation, some of the feelers will be sure to contact the high places It or M and some will be sure to engage the cavities H or l2, since the depressions and feelers are equally spaced on the check testing apparatus and coin respectively, but the number of feelers and depressions being unlike.

Figure 4 shows a slightly modified form of the invention in which the coin l5 has a plurality of evenly spaced depressions [6 in one face therefaces of the coin l5. Since the surface configurations of only one face of the coin are tested when the coin is inserted into the check testing apparatus, it is evident that the relative position of the depressions on opposed side of the coin to the depressions on the tested side, does not materially matter except from a manufacturer's standpoint. form the stamps or dies in such a manner so that the coin or check will be stamped with the depressions bearing a staggered relation to each other on opposed faces of the coins Figure 5 shows another slightly modified form in which a coin 20 has a plurality of concentrically spaced circular depressions 2| disposed in one face thereof and a plurality of circular spaced depressions 22 disposed in its other face. These depressions on the opposed sides of the face bear a staggered relation to each other as is shown in Figure 4. Likewise, in this form, the portion 23 of the coin which is disposed between the depressions 2| or 22 is at the same level as the other surfaces of the coin.

It is therefore, seen that I have provided a check or coin of predetermined thickness and diameter, said coin having a plurality of radially disposed depressions in each face thereof with ridges or high spots between said depressions so that the coins may properly comply with surface configuration tests applied in any coin testing apparatus having a plurality of radially disposed feelers for testing the surface configura- In many cases it is desirable to tions which feelers are of uneven number from the number of depressions in the face of the coin tested.

In the drawing and specification there has been set forth a preferred embodiment of the invention, and although generic terms are employed, they are used in a generic anddescriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.

I claim:

1. A check for use in a check controlled apparatus wherein a plurality of feelers are arranged in a circle for engaging one side of the check near its periphery, said check having a plane surface on each side thereof and each plane surface having a plurality of spaced depressions therein arranged near the periphery of the check in a circle whose center is the center of the check, the spaced depressions on one side of the check being disposed in a different radial plane from the depressions on the other side of the check.

2. A circular check for use in check controlled apparatus and having a pair of opposed plane side surfaces each provided with a plurality of equally spaced depressions arranged near the periphery of the check in a circle whose center is disposed at the center of the check, the spaced depressions on one side of the check being disposed in a different radial plane from the depressions on the other side of the check.
