  • Patent number: 5050321
    Abstract: To ease the mounting of a snow plow structure by use of a measured means extending between the attaching structure fixed on a vehicle and its lift chain to bring the hitch pin holes of plow structure push arms into vertical alignment with pin holes on attaching structure as the plow structure is lifted from its center of gravity and in fore and aft balance. Little movement, if any, of the lifted plow structure will be needed to transversely align pin holes for the full insertion of the hitch pins. A single pull cable is connected to two spring actuated hitch pins to pull them from the pin holes on the vehicle mounted attaching structure when connecting the plow structure thereto. Upon release of the pull cable the pins will enter the transversely-aligned pin holes of the structures. All this having been done with little manual effort.

  • Patent number: 5038895
    Abstract: A disc brake mechanism, including an integral mechanical parking brake assembly and having automatic wear adjustment features, is disclosed. The adjusting mechanism comprises an axial thrust screw having one end exposed to atmospheric pressure to create an axial hydraulic differential pressure acting thereacross. An adjusting nut is threadably received on the thrust screw and normally engages a hydraulic actuating piston such that the adjusting nut is free to rotate with respect to the thrust screw and piston. Hydraulic pressures acting upon the thrust screw create opposing forces, the resultant of which is applied to a resisting mechanical spring. So long as the hydraulic pressure is below a predetermined value, the resultant hydraulic force acting upon the thrust screw is insufficient to overcome the resisting spring force and the thrust screw remains stationary.

  • Patent number: 4991426
    Abstract: Method and apparatus for testing leak integrity of a workpiece such as a wheel rim in which the rim is positioned within an air-tight housing with the axial rim edges is sealing engagement with opposed wall portions of the housing so as to form first and second chambers within the housing internally and externally of the rim. One of such chambers is supplied with air under pressure. Microphones are positioned in the other chamber for detecting leakage of air through the rim as a function of intensity of ultrasonic radiation emitted thereby. The test apparatus is calibrated to detect air leakage that exceeds a pre-specified maximum allowable air flow rate by removably mounting a calibration orifice on a test workpiece, with the orifice being sized to provide the pre-specified maximum allowable leakage flow rate for a satisfactory workpiece at the operating pressure of the apparatus.
