Abstract: A flexible wirelike retainer clip is adapted to hold a plurality of disc-like rings in a stacked assembly. The retainer clip is resilient and can be selectively actuated to hold the rings in a stacked position to facilitate handling for various purposes such as processing the rings while stacked, shipping the rings while stacked and to facilitate release of the rings for assembly to other components. The resilience of the retainer clip facilitates accommodating stacks of rings within a range of varying lengths.

Abstract: A wire return spring for providing bias for brake shoes in a drum brake system urging the brake shoes to deactuated positions, with the wire spring having a circular like contour as assembled with the brake shoes.

Abstract: The method of manufacture and product by process of a laminated nut comprising a plurality of conical spring discs or spring washers and a cage for receiving and holding the spring discs in a stacked, aligned relationship to define a central opening threaded to be matably received upon an associated threaded bolt, with the cage comprising a plurality of fingers nested within slots defined in the flats of the spring discs and including protrusion means at one axial end of the nut cage to preclude gripping of the nut by a wrenching tool at the one axial end.

Abstract: A process and apparatus for high pressure impact coating of portions of workpieces such as the threaded openings in fasteners in avoidance of contaminating undesired portions of the workpieces with the coating material. A metered quantity of coating material is charged into a passageway and moved by low pressure air to a chamber ahead of an atomizing nozzle. High pressure air is introduced to the passageway and the coating material is fogged into a chamber defined by the workpiece and cooling. Proliferation and impingement of the cloud on the selected surfaces follows under vented conditions. A constriction in the vent line achieves the necessary delay and sets the system for accomplishing the coating. The machine structure facilitates use of the coating device with a wide range of female threaded fasteners and achieves the process steps while providing for flushing the lines and drying the working structure.

Abstract: An improved spring damper assembly is disclosed which comprises a helical coil spring having a generally cylindrically shaped sleeve member fitted thereto. The sleeve member has resilient sidewall portions which are designed to frictionally engage surfaces of the coil spring so as to dampen the oscillatory movement of the spring member whereby resonance of the spring is attenuated. The sleeve member includes a continuous integrally formed radially extending flange portion at one end thereof which overlies the end coil of the spring and operates to prevent excessive wear and/or gouging of the seating surface against which the spring is intended to bear due to rotational movement of the spring assembly during cyclic operation thereof.
