Abstract: This belt buckle is characterized by having its belt-catching finger, or pin, arranged to also be used as a key or the like. A rigid flat sleeve has a dependent leg pivotally mounted on the transverse pin of the buckle to which one end of the belt is attached. The sleeve overlies the buckle. The flat head of the key is adjustably fixed within the sleeve. Keys, of various shapes, sizes and thicknesses, can be used. The belt-catching finger comprises a key-like main portion removably mounted within a T-shape casing, which is itself pivotally mounted on the frame of a belt buckle for its removal to cut key notches in a portion thereof, or to be replaced whenever desired.

Abstract: A coded security system for an electrical circuit energizing safety lights installed on a vehicle is disclosed. The system comprises a bank of series connected toggle switches which can be operated in one position following a predetermined code for completing an electrical circuit through the terminals of all the switches, means for connecting one terminal of one of the toggle switches to a source of power, and means for connecting one of the terminals of the last toggle switch in the series to the circuit, whereby operation of the toggle switches following the predetermined code will complete the electrical circuit and energize the circuit.

Abstract: A wheel attachment device adapted to provide anti-skidding of a traction wheel of a vehicle and which is characterized by a simple and sturdy construction, and a pair of separate clamping devices easy to put in place on the wheel, which are compactly stacked one on the other for stowage such as in the trunk of a car, and which are adjustably slidable relative to each other. The anti-skid wheel attachment device comprises the pair of separate clamping devices with each a pair of laterally spaced apart bars which form at one end a tire clamping portion and at the other end a connection portion. The connection portion of one clamping device slidably overlaps the other, a locking lever adjustably slides the clamping devices toward each other and a single catch holds the locking lever in operatively locking position and connects the two clamping devices.
