Abstract: An apparatus for manufacturing split pulleys includes a frame and a spindle assembly supported by the frame and having an upper and lower spindle for supporting for rotation a blank to be split therebetween. The lower spindle includes a clamping mechanism having a screw means for drawing the upper spindle toward the lower spindle and the lower spindle toward the upper spindle to clamp the blank to be split therebetween. Bearing means are disposed between the frame and the spindle assembly for supporting the spindle assembly for rotation. The clamping means are operative to exert a clamping force between the upper and lower spindles which is isolated from the frame and the bearing means to clamp a blank therebetween. A pair of rotatable tools are provided each of which has an axis of rotation parallel to the axis of rotation of the spindle assembly and each of which is associated with a motor means to effect rotation of the tools.

Abstract: A differential gear mechanism of the side gear type includes the provision of an annular extension from one side gear which provides a housing and a bearing surface for the pinions at the differential. An oscillating weight member is carried by the annular extension. The member senses the occurrence of differential rotation between the side gears and actuates a locking mechanism upon the occurrence of a predetermined degree of differential rotation.The differential as disclosed comprises a transfer case operative to transfer power from the prime mover of a four wheel drive vehicle to its front and rear drive axles.

Abstract: An adjustable vehicular steering column utilizing telescopic support members, which are not coaxial with respect to the steering column, permitting infinite adjustment between predetermined limits. A releasably engageable locking mechanism is provided to apply a clamping force on the telescopic support members when the steering wheel is properly positioned by the vehicle operator. An auxiliary locking mechanism is provided as a safeguard in case the main locking mechanism fails.

Abstract: An automatic fastener emplacement mechanism for selectively applying fasteners, such as spring clips, to a work piece is provided. The mechanism preferably includes a vibratory hopper or other storage means for receiving the spring clips in bulk and properly orienting same on a track and an assembly tool having a nose piece for properly positioning the tool relative to the work piece and a ram for driving the fastener onto the work piece. Placement of the work piece properly within the nose piece will result in contact and/or displacement of an actuation member or trigger by the work piece which will cause a single fastener such as a spring clip to be fed, preferably by known means such as pneumatically through an escapement down a delivery tube, directly from the hopper track to the work piece. The clip is held in the nose piece against the work piece by the continued introduction of compressed air into the tube. Thus, the nose piece does not require a stop member or a catcher/holder mechanism.

Abstract: A temperature responsive viscous drive coupling having a working chamber which substantially conforms to the rotor. The coupling has a housing which defines a central cavity divided by a plate into a reservoir and a working chamber. A rotor is rotatably supported relative to the housing and located within the working chamber. The housing and the plate closely conform to the configuration of the rotor to reduce to a minimum the space within the working chamber surrounding the rotor. Dimensions are maintained between the plate and the rotor and the housing and the rotor which are generally no greater than fifty to seventy thousands of an inch. These dimensions are within acceptable manufacturing tolerances to insure that rubbing does not occur between the rotor and the housing or the plate. In such an arrangement, the volume of the fluid in the working chamber when the coupling is in the static condition will be about one-third or less than the total volume of fluid within the coupling.

Abstract: A hard surfacing, high temperature alloy comprising chromium and molybdenum in a nickel base having up to about 3.5 weight percent carbon, and structures surfaced therewith.
