Abstract: A pinion support is disclosed for use with a motor set on a gear box casing and an output drive pinion having an axial recess at the outer end of the pinion. The pinion support includes a housing which is rigidly secured against movement to the gear box casing and includes a portion which overlies the outer end of the pinion. A pin is rigidly secured to the portion of the housing and this pin extends coaxially into the axial recess at the outer end of the pinion. A bearing assembly is operatively positioned between an outer surface of the pin and an inner surface of the pinion recess. The pinion support is particularly well suited for use in an automotive framing system.

Abstract: A hemming machine of the type having a base, a nest for supporting a sheet metal part to be hemmed, and at least one die is disclosed in which the nest supporting the part to be hemmed is vertically displaced against the dies in order to form the hem. The improvement includes at least three elongated and external shafts wherein each shaft has one end rotatably mounted to the base so that the shafts are spaced apart and parallel with each other. A nut threadably engages each shaft, and these nuts are swivelly secured to the nest which permits a small amount of angular and radial deflection of the nut and shafts during movement of the nest from its lower to its upper position.
