Abstract: A coin handling protection device is disclosed which prevents thieves from stuffing compressible material through the coin insert slot and into the coin return chute of coin-operated machines. The device prevents stuffing the coin return chute by incorporating a blocking plate across the top opening of the coin return chute such that compressible material stuffed into the coin insert slot is diverted into the open space within the payphone unit. The device is suitable for use in existing coin handling apparatus.

Abstract: A telephone is secured against vandalism involving inserting a bare electrically conductive wire through the slot in the MEDECO lock securing the upper housing to the main housing. The free end of the inserted wire is made to contact either the "12" or the "1" terminal on the key pad on the back of the dial housing, to place system ground on the relay controlling the coin switch at the bottom of the chute for inserted coins and neutralize it so that coins can not be released to the coin box if a call is completed nor to the coin return bucket if a call is not completed. An advantageously shaped and located and mounted wire guard prevents the vandalism. The thin guard includes a wire blocking portion, a flange mounting portion, and intermediate portion connecting the blocking and mounting portions, and an inturned portion on its free end for overlying the terminals.

Abstract: A telephone is secured against vandalism by a double layer face plate or assemblage of tough materials. The assemblage consists of an outer plate covering most of the front of a telephone upper housing or casing, and a second layer covering the housing casing in areas not covered by the outer layer. Two such areas are those which involve openings in the outer or first layer for mounting the standard information pads above and below the dial push buttons. The second layer is open in the area of the push buttons, but the outer layer is provided with a grid thereat for preventing the housing or casing pushbutton grid from being pried out. The outer plate may be provided with wings to also secure the sides and top of the housing or casing against drilling and the insertion of a wire to pin the coin switch vane or to ground the coin switch relay to hold up deposited coins. The outer plate may also be provided with depending portions to cover the telephone coin box and coin return bucket.

Abstract: A coin-operated pay telephone is made secure from the removal of the coin return mechanism by a vandalizing bar and the subsequent collection of returned coins by vandals. A security bar is inserted behind the coin chute and down through an opening in an intermediate strengthening plate to block rocking of the coin return mechanism by a vandalizing bar and its translation forward out of the casing through the opening in which a finger is normally inserted to retrieve coins for incompleted telephone calls. The security bar includes a shoulder which rest on top of the rear edge of the coin return mechanism. The rear of the security bar includes a horizontal slot which is received on the portion of the strengthening plate behind its opening to prevent displacement of the security bar.

Abstract: An attachment for a carpenter's folding ruler has an elongated body with a longitudinal slot. The slot is dimensioned to accept the ruler and the ends of the body have flat sections against which part of the ruler can be folded to form certain angles. One of the ends makes a 90.degree. angle with the axis of the slot while the other end is at some angle less than 90.degree.. A level is provided on the body so that it may be vertically or horizontally positioned.

Abstract: A horseman's pocket knife has a handle into which a plurality of useful blades can be folded. The knife includes a hoof-cutting blade with a cutting edge along one side. A hook-shaped cross section is established at the end of the hoof-cutting blade and its tip is also provided with a cutting edge. The width of the hoof-cutting blade toward the hooked end and the size of the hook are dimensioned so that the cutting blade can be folded into the handle without interferring with the handle or other blades. A hoof-cleaning blade in the shape of a hook in the plane of the blade may also be provided for removing stones and other debris from the horse's hoof.
