Abstract: A cable and locking and sealing device which has a body member to which one end of a cable is attached and the other end passes through a hasp so as to lock it and then the free end of the cable is inserted into the body member in a first direction, but it cannot be removed in the second direction. A disk rides upon a ramp to lock the second end so that it cannot be removed from the body member and in the present invention, a flexible O-ring of rubber or "NEOPRENE" or other flexible material serves as a spring to bias the disk upwardly along the ramp to lock the cable.

Abstract: A boat lift in which a hydraulic pump and cylinder with a piston is mounted on a manual boat lift so that the piston rod carries a pulley which engages the lifting cable so that when the piston moves in the cylinder the boat will move up or down.

Abstract: Cable locking and sealing device which has a body member to which one end of a cable can be attached with the other end free to pass through a hasp or other device to be sealed or locked and in which the free end can then be inserted into the body member and can be freely moved in a first direction into the body member but which is clamped so that it cannot be removed from the body member in a second direction. Within the body member there is provided an inclined ramp at a small angle formed with a plurality of gear teeth and a locking gear formed with gear teeth which mate with the gear teeth on the rack and is movable along the ramp so as to lock the second end of the cable to the body member when force is exerted on it to remove it from the body member.

Abstract: A tamper proof attachment system is provided to secure a device such as a radio or tape deck in a vehicle. The looped cable passes through an anchoring point and the ends of the looped cable are locked and pass through an attachment device. The attachment device housing has an aperture in one end through which a mounting bolt is positioned and the head of the bolt is free to turn within the housing. The mounting bolt also passes through a mounting bracket and is threaded into a mounting surface of the vehicle. An open end of the attachment device housing is closed by a plug to cover the head of the bolt. In one embodiment the plug has apertures which align with apertures in the housing to permit the cable to pass through and to retain the plug in place. The device such as a tape deck or radio is fastened to the mounting bracket by bolts having tamper proof mounting covers according to the invention.
