Abstract: A parking locking system for an articulated or swing-type tricycle. A parking lever mounted to the handlebars of the steerable wheel actuates a cable and a rod. The rod engages a spring loaded slideable pin member into a hole in a plate fixed to the front frame of the steerable wheel. If the pin is not aligned with one of the holes in the plate, the spring will deform and the pin will slide relative to the rod. Upon further rotation of the front handlebars to a position where the pin member is aligned with a hole, the compression in the spring will cause the pin to interengage with the fixed plate thus locking the front steering wheel. The actuation of the cable interengages locking arms with a plate attached to the front of the swing shaft and with a parking gear in the drive train, respectively. A spring-loaded lever resisting interengagement of the locking arms is used to create tension in the cable and retract the locking arms when the parking lever is deactivated.

The rod has a pair of arms which extend in parallel planes and are interconnected by a 180 degree bend. Each of the arms is L-shaped. The arms are spaced such that they can be threaded (1) through a conventional bicycle pedal, (2) among the spokes of the bicycle's rear wheel, and (3) about a pair of bicycle frame members, whereafter the bracket can be locked in place using a conventional padlock.

Abstract: A device for preventing the theft of a motor vehicle employs a casing that encloses the vehicle's distributor in a virtually impenetrable shell. A stack of rotatable discs in the casing must be properly set in the manner of a combination lock to enable the high voltage electrical signals from the distributor to fire the spark plugs of the engine. The discs in the casing are set by dials within the passenger compartment of the vehicle. The discs have contacts on their surfaces which align when the discs are properly set to provide electrical paths from the distributor to electrical connectors outside the casing. The high voltage electrical ignition harness wires for the spark plugs are attached to those outside connectors. A cover is secured to the casing in a manner that enables the casing to be opened only when the discs are aligned in a pre-established relation, which can be different from the relation that enables the engine to be started.
