The lower edge of the coin engaging the pawl 42 and the plunger 38 being carried forward by its spring 39, and the spring 30nrging the rod32 forwardly, causes the coin to be released from between the plunger and plunger rod and to be deflected downwardly from the rod into the bottom of the cabinet.

A suitable tray or other receptacle 45 is.

mounted in the cabinet beneath the frame 24 for receiving coins released by the dog 42.

A relatively simple and expedient means is provided for detecting and throwing out coins of a spurious nature, wherein the checks or slugs are made of soft iron or the like which are susceptible to the influence of magnetism.

As is shown in the drawings, the coin slots 86 are grouped into pairs and the slots of a pair are provided with vertical openings 46 in their opposite sides so that the openings 46 face each other and theopenings are located'near the upper ends of the coin slots 36 but are of sufficient width to admit of the free discharge or passage of slugs or the like which are deposited in the upper ends of the coin'slots 36. Between each pair of coin slots 36 is located a magnet 47 which may be of bar form as shown with the pole pieces or extremities disposed only at the top of each opening 46. When a spurious coin is deposited in the slot, the coin is attracted by the magnet to the open side of the coin slot with the result that the coin is deflected downwardly toward and through the opening 46 ofthe coin slot.

The magnet 47 is of sufficient strength only to deflect the passage of the slug downwardly and laterally outward through the opening 46 so that after the slug has been deflected through the opening 46, the weight of the slug is such that it will not hang by the magnet but will be finally released from the magnet near the central portion thereof so that the slug will fall downwardly between the slots 36 and therefore cannot pass to the coin holder 34.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is 1. In a vending machine, a cabinet, a frame mounted substantially horizontally in the cabinet, a hollow plunger mounted in the forward end of the frame and biased to a forward position, a plunger rod mounted in the rear'end of the frame in line with the plungerto receive the latter telescopically thereover when the plunger is depressed, a cross bar secured in the frame adjacent the normally disposed rear end of the plunger and having a plunger receiving opening therethrough, and a coin slot member secured through the wall of the cabinet and having a coin socket on its lower end fitting in said frame adjacent said cross member and in line with'the forward end of the rod and having therein a coin receiving depression adapted to aline with the plunger receiving opening of the cross member, said coin socket having means for interlocking engagement with said cross member to hold the coin socket and the slot member in adjusted position within the frame.

2. In a vending machine, a cabinet, a horizontal frame in the cabinet, a hollow plunger mounted in the forward end of the frame and biased to a forward position, a plunger rod mounted in the rear end of the frame in line with the plunger to receive the latter telescopically thereover when the plunger is depressed, a cross bar secured in the frame adjacent the normally disposed rear end of the plunger and having a plunger receiving opening therethrough, a com slot member mounted in the cabinet and projecting through a wall thereof to receive a coin, a socket carried upon the lower end of the slot member and having a coin receiving depression therein in line with the forward end of the rod for supporting a coin from the slot member, and a pair of hooks carriedby the socket member in enga ement over said cross plate of the frame or interlocking the socket with the plate and holding the lower end of the socket member in line with the plunger.

In testimony whereof I aifix my signature.
