The heel end of each arm of the stock piece has a flat, rectangular recess formed in the ground surface face which is from 40%-60% of the depth or thickness of the shoe stock. A transverse groove is formed in the central portion of the recess. The groove has walls which are perpendicular to the surface of the groove and there is a threaded aperture formed in the base of the groove. The foregoing is dimensioned to receive a complementary piece secured in the recess. The complementary piece has a transverse extension or lug extending into the groove.

Abstract: A change return protection device is disclosed which prevents thieves from stuffing flexible material into the change return chutes of coin-operated machines. The device prevents stuffing of the change return chute when the change return door is opened by incorporating a blocking flap and a swinging flap around which the flexible material cannot be inserted. The device also includes a reinforcement plate which more securely joins the blocking flap to the change return door and a flat plate having V-shaped notch with sharpened edges which further prevents stuffing. Finally, the device includes an adjustable screw which restricts the size of the coin return door opening. The device is suitable for use in existing change return mechanisms.

Abstract: An improvement in a coin operated device having coin return bucket and a bank box wherein the coin return bucket and the bank box are mounted within the device near a bottom wall of the device. The improvement relates to preventing tampering with and/or vandalization of the device by cutting or penetration of a bottom wall of the coin return bucket or the inner wall of the bank box. The improvement lies in the use of a bottom wall protection plate which prevents tampering and/or vandalization and which is inserted between the bottom wall of the device and the bottom of the coin return bucket and an inner side wall protection plate inserted between the inner wall of the coin return bucket and the inner wall of the bank box.

Abstract: A change return protection device is disclosed which prevents thieves from stuffing flexible material into coin-operated machines' coin return chutes. The device seals off the change return's change return chute when the change return door is opened, and it prevents stuffing of the change return chute by also incorporating a blocking flap and a slot blocking plate around which the flexible material cannot be inserted. The slot blocking plate has a V-shaped notch itself having sharpened edges which further prevents stuffing. In a preferred embodiment the edges of the notch are formed from two crossed replaceable razor blades which are removably mounted in the device. The device is suitable for use in existing change return mechanisms.
