摘要:
A vehicle anti-theft device which is mounted on or in the instrument panel of said vehicle and which is connected into the brake fluid line that extends from the master cylinder to the brake wheel cylinders. By closing the valve while the vehicle brake pedal is depressed, fluid under pressure is trapped between the anti-theft device and the wheel brake cylinders, locking the wheels. The closed valve prevents reverse flow of the pressurized braking fluid until an authorized person in possession of the proper dial symbol to reference mark combination once again manually reorientates the set of dials that are attached to a plurality of cylinder valve port tubes and one spool that are rotated in proper sequence to bring all the tube ports in alignment with the casing ports. The valve consists of a body or casing and a plurality of cylindrical valve port tubes and one valve port spool (preferred number being three) the largest of which slips into the casing bore with each of the other cylinders or spools of progressively decreasing diameters their outside diameters fitting each of the compatible inside diameters, and then are held in that position by a securing device at each end; in the case shown, snap rings at one end and calibrated dials at the opposite end. The combination feature eliminates the inconvenience of carrying an extra key such as is required in the cases of some prior art.

A vehicle anti-theft device which maintains the braking function of the braking fluid by preventing reverse flow thereof from the wheel cylinder back to the master cylinder until, following an authorized procedure, an interconnecting fluid passage is moved into a strategic position which allows this reverse flow. As an improvement over the prior art, the direction of application of the braking fluid is arranged to assist, rather than impede, the strategic positioning of the aforesaid interconnecting fluid passages as well as contribute to other noteworthy advantages in the operation of the within device.

A vehicle wheel lock assembly for enabling the operator of a vehicle having a frame to lock one or more of the four wheels, at will, when the vehicle power is inoperative, which includes a normally retracted reciprocal locking rod mounted on and movable transversely of said frame adapted when advanced to interlock with a wheel. The normally retracted reciprocal actuating rod mounted on said frame for longitudinal movement. The control housing within the vehicle supports a control lever which projects from the housing and is operatively connected to the actuating rod for effecting selective reciprocal movements thereof. Gear mechanism on the frame interconnects the locking rod and the actuating rod.

For use, for example, in an anti-theft device having a lock, a piston moves in a cylinder having variant bores which provide upper and lower tapers. During factory assembly, a soft metal liner is deformed upon such tapers whereby to prevent, during later operational use, unwanted leakage of a pressure fluid either within or to the outside of the piston-cylinder assembly.

An apparatus for locking the gear shift stick and handbrake lever of a motor vehicle. The apparatus is a cylindrical body having a bore therein terminating in an open end which fits over the handbrake lever. The open end of the body holds a bolt which can be locked therein by a padlock and which abuts an enlarged portion of the handbrake lever preventing removal of the body therefrom. The other end of the body has a hook-shaped gripping member which simultaneously tightly holds a portion of the gear shift stick.

An improved brake locking apparatus for hydraulic brake systems having an accumulator and an accumulator control unit. A pressure control element in the accumulator maintains a fluidic pressure in a closed brake system equal to that of a precharged pressure. A pair of sequentially operated lock valves in the accumulator control unit block fluid flow from the brake cylinders to the master cylinder when the braking system is locked, and sequentially unseat to gradually release the back pressure flow to the master cylinder when the braking system is unlocked. Control valves in the accumulator control unit cooperate with the sequentially operated lock valves to allow fluidic precharging of the accumulator by the master cylinder when the braking system is locked, and isolate the accumulator from the hydraulic braking system when the braking system is unlocked.
摘要:
A theft-prevention ignition system having a plurality of normally open switches selectively located throughout a conventional ignition system and a plurality of normally closed switches located throughout the system whereby the vehicle is disabled. A multi-contact switch assembly contains the normally open and normally closed switches and includes a mobile electrically insulating plate which must be inserted into the switch assembly to permit operation of the vehicle.
摘要:
An antitheft apparatus for use on a vehicle comprising a key operated valve adapted to retain fluid in the brake lines of the vehicle so that the brakes remain applied. The valve for use in the system being specially formed so that fluid pressure tending to hold the valve closed will not make it difficult to turn the key to open the valve.
