Abstract: A winch mounted to an automobile bumper and having a cable winding drum supported between a main drive housing and an oppositely positioned idler housing. The drive housing connects to the bumper braket by means of a pair of convexly curved mounting lugs which permit limited angular movement of the drive housing with respect to the bumper. The idler housing has a flat mounting surface which fits flush against the bumper bracket surface to prevent such angular movement. Upon distortion or misalignment of the bumper braket, the drum is able to shift angularly with respect to the idler housing, while the other end of the drum maintains a fixed angular relationship with its bearing means in the main drive housing, which is in turn able to shift angularly with respect to the bumper bracket.

Abstract: A winch mounted to an automobile bumper and comprising a cable winding drum rotatably mounted between a main drive housing and an opposite end idler housing. The main drive housing has a main lower section of integral box-like construction and an open top closed by an upper housing section. The drive end of the drum and an intermediate drive member are inserted laterally into the lower housing through access openings, and are retained in place by a downwardly inserted retaining plate. The remaining drive components are inserted into the lower housing section through the top opening or positioned in the upper housing section. This construction provides for easy assembly of the drive components, with box-like construction of the main housing being better able to withstand the substantial force loads exerted thereon.

Abstract: A winch having a clutch-brake assembly comprising a ratchet plate with a constantly engaged pawl, and two clutch shoes. With a tension load on the cable of the drum, two rotatably mounted cam members engage each other to move the clutch shoes into engagement with the ratchet plate to cause power to be transmitted to the drum of the winch. Under minimal or no external load, after the power source has been operated shortly in reverse, a spring maintains the clutch shoes out of engagement to permit the cable on the drum to be reeled out freely at a moderate rate of acceleration.

Abstract: An automobile mounted winch having a clutch-brake assembly comprising a disc shaped ratchet plate positioned between two friction shoes, acting as a clutch in one direction and a speed governor in another direction, and a stationary brake. A plurality of friction buttons extend through the ratchet plate in a generally circular pattern, with each button engaging both shoes. Each button has an expanded head portion, and the buttons are oppositely arranged in an alternating pattern to centrally locate the ratchet between the two shoes and provide proper frictional engagement of the buttons with the shoes.

Abstract: A wheel hub assembly for a front wheel of a four wheel drive vehicle. The hub assembly has an unlocked position which permits free overrun of the wheel and a locked position where the wheel is fixedly secured to its drive axle. It comprises a conventional roller clutch mechanism in which there is an outer housing, an inner driving hub and a roller clutch assembly mounted between the housing and the hub. A clutch lock assembly, connected to the housing through a spring connection, is positioned in the outside portion of the housing and comprises a lock cage having a plurality of lock fingers that are movable axially inwardly to engage related slots in a roller clutch cage and thus mechanically interconnect the outer housing to the roller clutch assembly.

Abstract: A power transmission capable of transmitting power to both the front and rear sets of wheels of a vehicle, and also to automatically selectively transmit power to the slower rotating set of front or rear wheels. The transmission comprises an inner driving hub which acts through two interconnected sets of overrunning roller clutches to drive either or both of a forward and rear annular driven output member. The forward driven member is connected through a laterally extending chain drive to in turn drive a forwardly extending propeller shaft to transmit power to the front set of wheels to the vehicle. The rear driven member acts through a rearwardly extending propeller shaft to supply power to the rear set of wheels.

Abstract: A positive drive differential to drive either or both of a pair of co-axially mounted axle-driving hubs, and to permit free overrun of either hub. There are two sets of roller clutch elements between the two hubs and the drive casing, and these are positioned in two cages having inwardly extending radial flanges located proximate each other between the two hubs. A pair of contiguous spring loaded washers, mounted centrally in the differential, press axially outwardly against the cage flanges to cause frictional engagement of the cage flanges with the hubs. This in turn causes the hubs to be further pressed outwardly against the drive casing to cause frictional engagement of the two hubs with the drive casing.
