Abstract: An automobile anti-theft device is provided with a first cover which fits over a steering column-mounted ignition lock, a second cover which fits over the turn signal housing on the steering column, opposite the lock, and a flexible element that extends from one end of the first cover, wraps around the steering column over the second cover, and locks in the other end of the first cover.
Abstract: An upper mount assembly for a suspension strut which incorporates an elastomer bushing operatively connecting the piston rod to support structure that works in shear over initial travel but has compression load buildup at the limit of mount travel. The mount assembly is a unitized multi-element construction having a jounce bumper to provide a load path for suspension spring assist and a load deflection curve to improve suspension characteristics. In this invention, load buildup is achieved in jounce and rebound with the use of a rate washer which is moved upwardly by the strut in jounce movement. Initial travel works the bushing in shear but the elastomer becomes compressed between the washer and an outside metal wall to provide increasing spring rate. When the rod moves vertically downwardly in rebound, the washer controls the load buildup and compresses the upper portion of the jounce bumper for soft entry into rebound.

Abstract: An apparatus for adjusting the position of a seatbelt webbing fastened to the body of an occupant at which it is retained by the body of a vehicle has a base member secured to the vehicle body, a main shaft rotatably supported by the base member and having an external thread formed on the outer periphery thereof, and a subsidiary shaft secured to the base member and extending parallel to the main shaft. A movable member is thread-engaged with the external thread of the main shaft and slidably fitted on the subsidiary shaft, whereby, as the main shaft rotates, the movable member is prevented from rotating by the connection with the subsidiary shaft but moves along the main and subsidiary shafts through the thread engagement with the main shaft. A guide member which retains the webbing is secured to the movable member. Thus, the position of the webbing at which it is retained by the vehicle body is adjusted.
Abstract: Apparatus for stabilizing a material handling vehicle during implement manipulation is provided. Dual hydraulic cylinders are provided on each side of the vehicle intermediate the vehicle's frame and a spring-biased solid axle. A lockout valve having a pneumatically actuated check valve in fluid communication with one-way check valves and flow restriction valves corresponding to each of the upper and lower ports of the respective hydraulic cylinders is mounted on the vehicle's frame and is in fluid communication with a reservoir of hydraulic fluid. When the vehicle is not caused to travel, the pneumatically actuated check valve is closed allowing no hydraulic fluid flow between the ports of the hydraulic cylinders and thereby locking the then-present fluid in each of the chambers of the hydraulic cylinders which prevents the movement of the pistons thereof and, hence, any displacement of the front axle relative to the vehicle frame.
Abstract: There is disclosed a ground wheel takeoff drive system for fertilizer spreaders or the like including a gearbox being adapted to reside at least partly inside one of the speader's pneumatic tire and wheel cavities and having a hollow shaft journalled therein through which passes the axle on which the tire and wheel is mounted. The hollow shaft is secured to rotate with the ground wheel and a restraining element causes the gearbox to be restrained from rotation. The gearbox has a sprocket which is geared to be driven from the rotating hollow shaft, a remote control cable arrangement is connected to a gear lever on the gearbox which slides a driven gear in and out of engagement with a gear secured to the hollow shaft so that the gearbox sprocket motion may be disabled or enabled from a remote position; a sprocket chain is provided with suitable idlers for driving a sprocket wheel connected in a conventional manner to the gear drive mechanism for the fertilizer spreader.
Abstract: An adverse terrain vehicle is provided which includes a system for controlling a number of vehicular functions. The vehicle includes at least two variable displacement hydraulic motors, each for driving at least one wheel member on one side of the vehicle independently of the wheel members on the opposing side thereof. At least two variable displacement hydraulic pumps are mounted on the vehicle for supplying pressurized hydraulic fluid to the hydraulic motor on one side of the vehicle independently of the hydraulic motor on the opposing side thereof. The hydraulic pumps are driven by an engine. A sensor detects a decrease in the power output of the vehicle below that selected by the vehicle operator. Overload protection circuitry is responsive to the overload sensor and adjusts the displacement of the hydraulic motors and pumps to increase the power output capacity of the vehicle. Braking control circuitry coordinates with braking of the vehicle steering to effect turning of the vehicle while braking.
