f 6 Claims.

This invention relates to coin selectors and has as its object to provide a device that will select United States nickels from slugs of die-casting metalas well as slugs, checks, counterfeit coins,

and coins of other denominations.

In order to 'attain eflicient separation of the nickels from slugs of brass, copper, etc., an arrangement of bouncing block and magnetic field for producing eddy-current retardation, may be employed, as disclosed in my pending application.

Serial No. 166,763, led of even date herewith.

The present invention is not limited to that typeit is intended to be used in to secure complete from which the nickels will rebound but from which lead slugs, having little resiliency, will not rebound 'to any marked degree.

Slugs of die-casting metal, however, have proved very diicult to separate because not only their indifference to the magnetic eld, but their rebounding characteristic under conventional conditions, is quite close to that of the nickel.

discovery that such slugs may .be efficiently separated from nickels by bouncing both against a rebound member comprising a series of knife edges disposed so as to compositely form a serrated surface, the edges being position at right angles to the plane of travel of the coins. United States nickels will rebound from such a surface about as well as from a continuous flat surface, while slugs of casting metal will rebound very little. This is apparently dueto the fact that the casting metal, though as elastic as the nickelcopper alloy of the United States nickel, is softer, so las to be penetrated by the knife edges of the rebound member sufficiently to deaden the rebound.

Another object of the invention is to provide a coin selector embodying a bouncing block on which new coins will bounce as uniformly as will 0 older coins. Where a new coin with its knurled ridges still sharp, strikes a smooth-faced rebound member in such a position that the blow is centered with respect to a single one of the ridges, the ridge which thus the impact will be crushed-to such an extent as The present invention is predicated upon thev absorbs a major portion of- (Cl. 15M-100) to materially alter the rebound as compared to the rebound member that of a worn coin striking in the same manner, or as compared another new coin striking the rebound a. position in which the two ridges. The present non-uniformity of rebound.

Another object is to provide bodying a bouncing block, the coin surface of which all times. Old types o tendency to coins that are bounce interfere with proper the present invention, lodged from a coin into the bouncing lodge in the grooves rebound of the accompanying drawing, in which:

Other,` objects of the invention will become apparent from the following detailed description of the invention considered in connection with the Figure 5 is a sectional view of a modified form a web portion I6 secured by screws I1 to a base plate I8, on which the various parts ges I2 and I3 may be sepablock I9 of triangular shape.

Carried by the plate I8 below the oper.l lower II,is a rebound member comprising a'series of spaced upstanding plates 20 of to that of member in COIlS. In

p block will in section,

of the thin respective in connecthe platesigfi are between .008 and .015 inch thick at their upper edges and arespaced apart by spaces not less than .025 inch wide. mounted in spaced relation by means of spacers 2|. The plates 20 and 2I are perforated as at 22, and are secured in assembled relationship by a pair of screws 23 extended through a block 24, thence through the apertures 22, and threaded into an upstanding horn 25 of a mounting saddle 26, their, lower edges resting on a shoulder 21 at the base of the horn.

'I'he saddle 26 is mounted on the base plate I8 by means of a screw 28 extended through a round hole in one side of the block, and a second screw 29 extended through an elongated opening 30 in the other side of the saddle`,'arranged circumferentially with respect to the screw 28. Thus the angle of inclination of the rebound surface formed by the upper edges of the plates 20, may be adjusted.

The upper edges of the plates 20 are arranged at right angles to the so that the coin C, dropping through the passage I I along the path indicated by the broken line 80, will strike the rebound member in a position transverse to the said edges.

United States nickels are of suilicient hardness and toughness to rebound in an extended trajectory as indicated by the broken line 8|, so

30 as to clear the dividing barrier I8 and enter the acceptable coin outlet passage I2.

Nickels counterfeited from die-casting metal, although of suilicient resilience to follow substantially the same trajectory as that of genuine ickels when rebounding from a smooth-faced anvil, will be substantially stopped dead by the thin edges of the plates 20, and will thence enter the rejection outlet I8, as indicated by broken line 82. I attribute this result` to the fact that die metal is not as tough as nickel-copper alloy, and will allow the edges of plates 20 to penetrate it suiiiclently to substantially absorb the impact.

In the modification shown in Figure 5, the rebound member is formed by a series of blades 88, the upper edges of which arepbevelled to present a series of edges of spacing and thickness equivalent to that specified in thel preferred form.

The plates 20, or 88, as the case may be, are formed of hardened steeL.

Their upper edges are arranged in a plane,l

which inclinesdownwardly slightly in the direction-of the passages I2 and I8, so that the coins,

in rebounding, are deflected laterally.

'I'he invention not only solves the problem of separation between nickels and die-metal slugs, but, in addition, avoids a condition that is met in connection with brand-new coins on which the knurled ridges have'not been dulled. If such a coin strikes a smooth anvil so that the impact -is' taken by a single ridge, the latter will be crushed and absorb the impact so that the coin will not bounce properly. In the present invention, it is impossible for this to happen, for the reason that the knife edges will enter between the ridges and contact the solid body of the coin.

Since the edges are disposed at right angles to the plane in which the coins travel, the coins 'I'he plates 28 are@` plane of'the passage Il,"

. tioned to be contacted l selector, means for causing said coins to fall by will plane.

.1. In a coin selector, 'a rebound member A presenting l'a series of spaced thin edges in position 'to be contacted by a coin moving in a plane perpendicular to said edges, said edges being such that United States nickels will rebound therefrom to a sufficiently greater degree than will slugs of die-casting metal, so that the nickels and the slugs can be readily separated upon rebound, means for directing the coins onto'said rebound membeigand separatemeans for receiving coins having different trajectories upon rebound from said member. i,

2. In a coin selector, a rebound member comprising a series of extremely thin, hardened metal plates, an alternating series of spacers of greater thickness than said plates, spacing said plates apart, said plates projecting beyond said spacers to form a series of edges for contact by a moving coin, means for directing the coins onto said rebound member, and separate means for receiving coins having diii'erent trajectories upon rebound from said member.

3. In a coin selector, a rebound member presenting a series of spaced edges of extreme thinness, means to drop a coin upon said edges in a plane at right angles to said edges, and a pair of discharge chutes of said rebound member in positions to receive coins rebounding from said member, nickels being adapted to rebound to the far chute and slugs,

of die-casting material being adapted to fall short and` pass into the near chute.

4. In a coin selector, a rebound member presenting a series of knife edges for contact by a coin dropping thereon, means for directing coins onto said member, and means providing for rebound of the coins from said member including means for directing in separate paths coins following diilerent trajectories upon rebounding from said member.

5. In a coin selector, a rebound member comprising a number of blade .elements bound together and providing a series of knife edges upon the surfaces adapted to be contacted by coins inserted in the selector, means for causing said coins to fall by gravity onto said member, and means for receiving and directing into separate paths coins of diilerent bounding from said member.

6. In a coinv selector, a rebound member presenting a series of spaced thin edges posiby coins inserted in the gravity onto said member, and means for receiving and directing into separate paths coins of different degrees of resiliency rebounding from said member.
