Abstract: A damper insert for assembly in a tubular drive shaft of a motor vehicle includes a tubular sleeve, a helically wound, resiliently deformable wiper secured to the sleeve, and a corrugated winding secured to the sleeve. The wiper includes an arch that spans mutually spaced supports. The damper insert is sized to fit in the bore of the drive shaft such that the arch frictionally engages the surface of the bore and secures the insert in place within the shaft with a resilient press fit. The arch projects radially outward toward the bore beyond the radially outer surface of the winding.

Abstract: Anti-gear hopping device for a power transmission mechanism for an automotive vehicle. The power transmission mechanism may be a torque transfer case of a four wheel drive system. The anti-gear hopping device prevents undesired shifting between high range speed and low range speed modes of operation. The anti-gear hopping device comprises: (A) a fluid pressure mechanism for controlling the movements of a shift member; (B) a valve mechanism for actuating the fluid pressure mechanism; and (C) a valve actuator. The fluid pressure mechanism may include either a diaphragm or a piston which divides a chamber into two cavities which may be at different pressures. An output member linked to the diaphragm or piston controls shifting.

Abstract: An electric lamp assembly simulating the appearance of a gaslight for installation in an existing incandescent-type light fixture. The assembly includes an adapter which contains a screw in, incandescent-type base projecting from one surface thereof, and a receptacle for receiving the base of a fluorescent lamp on an opposed surface thereof. The lamp is surrounded by a translucent cover, and a fabric mesh encloses the cover. A wire frame assembly is disposed on the outside of the cover and mesh. The cover includes longitudinally extending ridges which diffuse the light emanating from the lamp, to present an appearance that looks similar to a gaslight. Also, the cover may be provided with a tint which, in combination with the mantle, provides the light emanating from the lamp with a color virtually identical to the color of light which would emanate from a typical gaslight.

Abstract: A shoe insert device comprises a pad of cushioning material having a forward portion for cushioning the forefoot of a user and a rearward arched portion which is thickened and shaped to conform substantially to the arch of a user's foot. The rearward portion terminates short of the heel region of the foot.

Abstract: An improved structure for retaining a differential cross shaft in a differential axle assembly is disclosed. The differential axle assembly includes a casing adapted to be rotated about an axis. A cross shaft is disposed within the casing perpendicular to the axis of rotation. A first elongate channel having a larger diameter portion and a smaller diameter portion is formed through the casing. A second elongate channel is formed in the cross shaft having a diameter greater than the smaller diameter portion of the casing channel. The cross shaft channel is adapted to be aligned with the casing channel. A lock pin is inserted through the larger diameter portion of the casing channel and the cross shaft channel into abutting relationship with a shoulder formed at the junction of the larger and smaller diameter portions. A boss is provided to extend into the larger diameter portion of the casing channel to retain the lock pin therein.

Abstract: An automotive differential has a differential case or rotor (20) rotatably mounted in a differential carrier (10) by a pair of spaced anti-friction bearings (30). The axial position of each of the anti-friction bearings is adjustable by virtue of a semi-cylindrical bearing retainer cap (40) which has an outer end face (40a) engaging an internally projecting shoulder (10c) in the stationary differential carrier and is provided with axially elongated slots (40c) for reception of mounting bolts (41) which engage threaded holes provided in the carrier adjacent a semi-cylindrical bore (10a) therein which functions as the other half of the bearing housing and which is machined with the bearing retainer in assembled position, thus permitting precise axial location of the bearing to permit axial positioning of the differential rotor relative to the carrier by a few shims (50) or an adjusting washer (60) to eliminate end play therebetween.
