Abstract: A motor vehicle security system for trucks, trailers and the like equipped with conventional fluid operated braking assemblies. The security system comprises a manually operable valve for controlling the application of fluid under pressure to the braking assemblies to manually set the vehicle brakes. The valve is arranged with a mechanical, key-operated lock for controlling and locking the valve in a selected position. When the valve is in a "locked" position it allows the brakes to be set and the vehicle maintained in situ to prevent the unauthorized movement thereof. The brake assemblies are also secured and locked to prevent the manual operation thereof by use of a conventional lockout tool.

Abstract: Wheel alignment apparatus for electrically indicating the alignment condition of a vehicle wheel in which there is sensing means, including an element adapted to be detachably secured to the wheel, for producing an electrical output dependent upon the extent of inclination of the wheel and an electrical display device having a movable member positioned in accordance with the electrical output of the sensing means. The sensing means is designed to selectively detect toe-in, camber, and caster.

Abstract: An automatic collet hinge/screw placement machine comprising a reservoir for bulk storage of screws, a vibrator segregating the screws into a plurality of magazines and an escapement mechanism for dispensing a set of screws essentially concurrently in time, the machine further comprising a table upon which the work, e.g., a cabinet door, is placed between stop structure for correctly locating the work. A hinge-holding/screw-placing head containing a collet for each screw of the set is mounted upon a reciprocating frame whereby the head is pneumatically lowered to position a hinge and a set of screws for placement following which the screws are inserted into the work through apertures in the hinge using a driver mechanism comprised of universal joints for each screw.
