7 Claims. (Cl. 194-97) This invention relates to coin testing devices, particularly that type known as a coin chute, in which coins gravitate past a testing means, such as a magnetic field, and follow a certain trajectory toward another testing means in the nature of a rebound anvil from which proper coins rebound past a reject opening into which other and improper coin elements fall by reason of .the'

Fig. 4 is a, fragmentary perspective of the outside of the chute showing the complete mounting of the deflector.

A principal object of the present invention is the provision of coin deflecting means for positively ejecting coin elements through a special exit opening when they follow a trajectory short of the normal trajectory toward the anvil.

A further object is the provision of a deflector for the purpose set forth and further characterized by the fact that it is movable in the general direction of movement of the coin in the chute passage and arranged to assume effective deflecting positions on opposite sides of a normal Y position whenever the chute is tilted in either direction from a normal position.

Yet another object is the provision of a discharge apron arranged to form a lower side portion of the main passage and provided with an edge portion defining one sideor margin of the special rejecting exit adjacent the novel deflector the invention reside in certain details of construction as well as the cooperative relationship of the component parts of the illustrative em-. bodiment described hereinafter in view of the annexed drawing, in which:

Fig. 1 is a perspective of the gate side of the coin chute showing the coin engaging portion of One type of chute with which the present in;-

vention may be successfully used includes a main plate member l0 having opposite vertical edge 7 portions ofiset laterally to provide side walls II" and having laterally offset ears l2 along. its upper edge to provide a mounting for a pintle rod 13 from which is suspended a swinging discharge ate l4.

The gate l4 hangs normally'in parallelism with the inside of the plate l0 and is spaced from the latter to define, in part, a coin passage I5 (Fig. '2) which descends from a coin entrance it to the region of the bottom edge of the main plate, -where there is arranged a beveled or pointed separator ll (Fig. 3) defining on opposite sides thereof an acceptance passage. or exit l8 and a reject passage IS. A rebound anvil 20 is spaced from the separator H on the opposite side of the passage l9 and is provided with a sloping rebound edge 2| arranged so that certain coins will be deflected over the reject exit l9 and the separator I1 into the passage I8,

Mounted on the inside of the gate I4 is an inclined coin runway 22 having its upper levels disposed substantially beneath the entrance l6 and terminating at its lower end 23 in the region generally above the separator l1 and the acceptance opening I8. In other respects, the lower edge portion of the gate is unobstructed, and the remaining lower portions of the main passage are guarded by a discharge apron 24 having an inner vertical surface portion 25 disposed in parallelism A sidewise reject opening 28 is defined by an edge portion 29 along the bottom of the gate and an opposite beveled edge portion 30 on the discharge apron.

In the usual operation of this type of chute, there is provided a testing means in the nature of a permanent magnet (Fig. 3) having poles 3| arranged adjacent the lower .end 23 of the runway to maintain a strong magnetic flux across the passage for the purpose of selectively influencing the trajectories to be followed by various coin elements in leaving the end of the runway, acceptable coins following a trajectory which cairies them down onto the edge 2|of the anvil from which they rebound appropriately over the exit l9 and separator l1 and into the acceptance exit l8. Unacceptable coin elements, both metallic and non-metallic tend, in general, to follow a shorter trajectory, that is, to drop oil? the end of the runway at a sharper angle and hence fall more directly toward the exit I9 or the separator ll. It frequently happens that some otherwise unacceptable coin elements, in following the shorter trajectory, strike the separator I! in such manner that they bounce back onto the edge 2| of the anvil and rebound over the separator into the acceptance opening.

In order to prevent false operation of the chute in the manner aforesaid and, in general, to provide for the positive ejection of all forms of coin elements which follow the shorter trajectories, there is provided a novel deflector in the form of a pin 40 (Fig. 4) projecting laterally from a pendent arm 4| through an opening 42 in the main plate H) of the chute so as tolie in the coin passage (Fig. 3) in the region generally between the end 23 of the runway and the separator l1 and anvil 20, the pin, in fact, lying almost directly above the separator IT. The arm 4| is pivoted as at 43 between an offset bracket 44 and an attaching strap 45 from which there is 2, depending T-shaped portion 46 provided with spaced pins 41, constituting stops for the arm 4|, to limit the swinging movement of the latter.

The strap 45 is mounted for adjusting movement on the outside of the main plate by means of a set screw 48 passing through an elongated slot 49 in one end of the strap, the latter having additional support at its opposite end in the nature of the pintle pin 43 (Fig. 3), which mounts the arms 4|, and which passes through the horizontally elongated slot 50.

As a result of this arrangement, the strap 45 may be shifted horizontally when the screw 48 is loosened, in consequence of which the deflecting pin 40 may be shifted in opposite directions generally toward or away from the end 23 of the runway, and hence into various positions with respect to the several possible trajectories of the coin elements leaving the runway.

It is important to observe in Figs. 1 and 2 that the pin 40 is slanted or beveled as at 40a so as toincline toward the reject opening 28. Any coins striking the deflecting pin will thus be deflected into the reject opening and over the knife edge 30 of the apron out of the chute in the manner illustrated by the coin C in Fig. 2. It should also be observed that in addition to its outward slope toward the reject opening and apron, the

surface 40a of the deflecting pin also slopes slightly toward the knife edge 30 and the reject opening l9.

When properly installed, the coin chute is fixed in position in a vending machine or other coincontrolled instrumentality, which is usually mounted on a level so that no particular adjustment need be made of the deflecting unit which has previously been adjusted at the factory. However, if adjustment is needed for any reason, the screw 48 is loosened and the strap 45 shifted to the right or left, as required, until the chute operates properly, whereupon the screw is turned up tightly. An important feature of the invention resides in the fact that the beveled or inclined part 40a of the deflector is calculated to effect the proper deflection of a coin even though the chute or apparatus with which it is associated may be slightly off level, the arm 4| being free to swing in opposite directions so as to maintain a predetermined operative relationship with respect to the end 23 of the runway, the separator l1, and anvil 28. In Fig. 3, the trajectory of a good coin in leaving the end of the runway is indicated by the tracer arrow A, and it will be observed that the latter coins follow a path which is far removed from the deflector. Certain slugs and unacceptable coins tend to follow a shorter trajectory, such as is generally indicated by the tracer arrow B, with a tendency to move down toward the pointed end of the separator ll. However, in following the shorter trajectory, coins strike the deflector 48 and are shunted out through the opening 28 in the manner aforesaid, which precludes any possibility of their rebounding either from the separator I! or the anvil 20 into the acceptance opening.

It may be explained that the gate I4 is mtended to be opened by operation of a lever 54, which causes an offset cam arm 55 to bear against a roller 56 on the gate and swing the latter outwardly, and at the same time a roller 51 bears against a cam edge of a sweep 58 and pivots the latter from its normal position so as to sweep across the poles of the permanent magnet and dislodge any coin elements or the like which may have been arrested thereby for movement through the open gate into the discharge apron 24.

The various advantages and objects of the invention may be accomplished by modifications of the particular embodiment specifically described herein, and it is intended that the appended claims shall include all equivalent arrangements fairly coming within their call.
