Abstract: A knuckle-supported wheelend assembly includes a shaft having a contoured peripheral surface portion proximate to an outboard end featuring a minimum radius and a maximum radius, and a hub mounted on the shaft's contoured surface portion via a complementary, contoured central bore. The nontapered contoured hub-shaft interface includes a slight twist or jog to reduce backlash and to permit a relative shortening of the length of axial hub-shaft engagement to as little as about 45% of the maximum radius, thereby advantageously reducing scrub radius for a given wheel-tire combination. By eliminating any required taper of the contoured interface, the hub's inboard face firmly abuts the machined face of the inner race of a knuckle-mounted, shaft-supporting bearing assembly to achieve reduced assembly runout. The hub's wheel-mounting face and integral annular friction surfaces are each machined with reference to the inboard hub face to ensure a high degree of parallelism.

Abstract: Identical ring-shaped metal blanks are machined whereby each blank forms a plurality of identical components. The blanks are first machined on both sides, and then a stack of the blanks is clamped axially adjacent one another on an arbor. Tools machine the blanks for reshaping the blanks. One of the tools is a slitter which makes axial cuts through the stack to separate each blank into a plurality of components distributed around the axis.
Abstract: The device uses a diaphragm cover between the adapter and the die to lock the die into the adapter. The cover is rotatably mounted onto the adapter and has a polygonal bore that matches the polygonal bore of the adapter. The mandrel of the die has a throat in which the cover sits when the cover is in the locked position. The cover is biased with a spring into the locked position. Stops are provided to limit the movement of the cover between the open and closed positions.
Abstract: A stabilizer box has a number of interconnected panels which automatically articulate to form a bottom which converts the box from a flat and knock-down shape into a cubical configuration. The box opens and the bottom locks in place simply by pushing on the opposite ends of the flat, knock-down shape. The top of the box is formed by four interconnected wedge or somewhat pie-shaped panels which snap down into the plane of the top of the cube responsive to a slight pressure of the thumb upon articulation panels. Each of the four wedge or somewhat pie-shaped top panels has a quarter circle, arcuate cutout, at the tip of the wedge or somewhat pie-shaped panels. The cutouts come together to form a variable circular opening when the top is set up.
