    Abstract: An apparatus and method for measuring toe in vehicle wheels. The apparatus ordinarily includes a pair of head units. Each of the head units is mounted upon one of the front wheels of the vehicle. Each head unit includes a projecting element for projecting a light beam generally laterally across the front of the vehicle and onto a target on the opposite head unit in determining front toe of the respective front wheels. Each head unit can also project a beam generally axially from the front wheel of the vehicle to a reflector on the adjacent rear wheel for determination of rear toe of the respective rear wheels. A metering device is connected operatively to signal generators on the head units for determining the toe in each front wheel in relation to a thrust-line reference calculated from the total rear toe of the vehicle.

    Abstract: A lightweight hydraulic jack having a gray iron sleeve embedded within a cast aluminum housing, a steel plunger mounted for reciprocal motion within the sleeve, the sleeve being provided with an annular shoulder and a number of longitudinal ribs to prevent movement of the sleeve with respect to the housing. Hydraulic fluid is pumped from a reservoir in the housing into the sleeve and from the sleeve back to the reservoir through steel valve seats which are positioned at the control points in a fluid passage network in the housing.

    Abstract: A seal for a vane type fluid pressure motor or pump. The motor or pump comprises a housing having a chamber receiving a rotor, an elongated bore extends through the housing and the rotor and receives a shaft which is drivingly engaged by the motor through a splined connection. A seal assembly is disposed on either side of the rotor to prevent leakage from the area between the side walls of the rotor and the side walls of the chamber and into the elongated bore. Each seal assembly is comprised of a cylindrical sleeve affixed to a side wall of the rotor and extends axially therefrom. The assembly is disposed in an annular recess in the bore at a point adjacent the rotor. The sleeve is affixed to the rotor for rotation therewith and is spaced from an undercut portion of the housing wall. The undercut defines the annular recess. An annular elastomeric sealing member is disposed in the recess and is affixed at its radially outward side to the recess wall and surrounds and snugly engages the sleeve. The oil seal assembly is independent of the shaft. The sealing member is constructed so that the leakage pressure assists in forcing the member into further sealing engagement with the rotating sleeve.

    Abstract: A truck has a cab tiltable between full-down and full-tilt positions by means of double-acting hydraulic lift cylinders. The double-acting cylinder and the control system therefor, which includes a manually, electrically or air driven pump and a manually operable selector valve, enables the cab to be positively moved from full-down to overcenter position whereupon the cab then slowly descends under the force of gravity to full-tilt position. Furthermore, it enables the cab to be positively moved from full-tilt position to overcenter position whereupon the cab then slowly descends under the force of gravity to full-down position. Each cylinder is provided with two integrally mounted velocity fuses as a safety feature. In the event of a hydraulic system failure, one fuse prevents free-fall movement of the cab when the cab is in any position between full-down and overcenter position. In one embodiment of the invention, both fuses are located in the lower end of the cylinder. In another embodiment, the fuses are located at opposite ends of the cylinder.
