Abstract: An auxiliary locking brake for tandem tires is formed by upper and lower wedge members centrally joined by a threaded shaft moving the wedge members toward and away from each other for impinging confronting thread surfaces of tandem tires when disposed therebetween. Telescoping members adjustably extending between panels forming the wedge members permit fore and aft adjustment of the spacing between the wedge forming panels prior to installation of the locking device on the tires of a particular vehicle. Tire retaining flanges on the wedge members prevent lateral movement of the device in a direction parallel with the axes of tandem axles.

Abstract: A vibration damper for the hollow drive shaft of an automotive vehicle has a liner press fitted into the bore of the drive shaft and a resilient, deformable, elastic, highly frictional retaining strip which forcibly bears against the surface of the bore and fixes the liner in place within the shaft.

Abstract: A radially resilient canted coiled springs includes a plurality of coils canted along a centerline thereof with each coil having a trailing portion and a leading portion. The disposition of the trailing portion is defined by a back angle between the trailing portion and a line normal to the centerline and the disposition of the leading portion is defined by a front angle between the leading portion and a normal line. Specific resilient performance, or load-deflection characteristics of the radially resilient canted coiled springs is determined by controlling a turn angle of the coil spring.

Abstract: A drum brake assembly having a parking brake actuating lever is so arranged that the parking brake cable end may be assembled in a blind fashion to the end of the actuating lever. The cable is provided with a button. The lever has a return spring which has one end attached to the lever and the other spring secured to the backing plate about a parking brake cable opening through the backing plate. The spring end attached to the lever has a retaining ramp and a hook end, the retaining ramp being above an open channel formed on the lever end and the hook end being secured to the lever one end above the channel. The cable button is inserted axially through the backing plate opening provided for the cable and through the spring, being guided by that spring, to a point above the channel open receiving end.

Abstract: A compact hydraulic mount is provided for mounting a vehicle engine, transmission or the like to a vehicle frame. The mount includes a substantially cylindrical elastomeric hollow body defining a primary or core hydraulic chamber. An approximately 270.degree. portion of the cylindrical outer periphery of the hollow body is surrounded and supported by a retainer cylinder. The hollow body additionally includes an integral secondary hydraulic chamber molded within the elastomeric wall. A portion of the retainer is inwardly, radially offset and separates the primary chamber from the secondary or peripheral chamber. The outside wall of the elastomeric body at the secondary chamber forms a resilient diaphragm. An orifice track is provided within the body to allow damping fluid communication between the primary and secondary hydraulic chambers. This flow of damping fluid between the chambers provides the damping action of the mount.

Abstract: A piston for a piston cylinder unit, particularly a gas spring, is to be provided with a piston ring and comprises a portion extending at least from the piston ring groove to a free end and consisting of a plurality of segments separated from one another by longitudinal slots. This portion is provided with a bore the diameter of which is at the free end smaller than the diameter of the related portion of the piston rod. It is the purpose of these measures to enable simple assembly of the piston ring in the piston ring groove and at the same time to ensure reliable seating of the piston ring.

Abstract: This specification discloses an automatic sheet supplying device for automatically feeding sheets from a sheet supporting table to a predetermined position. More particularly, the specification discloses an automatic sheet supplying device which is provided with a feeding member movable in a sheet feeding direction and a separating member opposed to the feeding member, whereby when sheets fed one by one by the action of the two members arrive at a predetermined position, the two members are caused to be spaced apart from each other to thereby eliminate any load against the sheets being conveyed.

Abstract: Disclosed is a line clamping device which may be remotely and repeatedly operated to clamp line passing through the device. Increasing pressure acting on a piston in the clamp housing moves slips to a position clamping the line while compressing a spring. When pressure on the piston is reduced, the spring moves the slips and piston to back to a position not clamping line.
