Abstract: A lever operated rotary reversing switch wherein a lever is snap-fit attached to the switch housing with a portion of the lever inserted under an overhang on the housing to maintain that portion of the lever against the exterior surface. A detent is provided between the overhang and the end of the lever to direct the forces longitudinally in the plane of the lever. A rotor plate located exteriorly of the housing is connected to the rotor by an axial shaft, and an eccentric received in a slot in the lever for providing a driving coupling between the lever and internal contact mechanism is located on the exterior surface of the rotor plate.

Abstract: A circular rotating aerodynamic toy for launching by hand with a spinning motion and which may be caught in flight by hand, has an outer peripheral rim or skirt with a free lower portion and an upper portion that connects to the circular body of the toy, the skirt being segmented and attached to the body at a multitude of discrete points around the outer periphery of the body so that between the discrete points of connection the body is free to bend and flex about diametric lines passing through any position on the periphery of the toy, whereby the toy is substantially more flexible than it would be if the attachment of the skirt to the periphery of the body were continuous around the periphery, and so impact forces of the toy upon colliding in flight with another body are minimized.

Abstract: A self-aligning mechanism for swivel caster comprising a carriage supported for rotation about a predetermined axis, a wheel mounted on the carriage for rotation about an axis at right angles to said predetermined axis and a coiled spring yieldable means interconnecting the carriage and support yieldably holding the carriage in a predetermined position of rotation relative to the axis and structured to permit the carriage to rotate continuously in either direction relative to said axis.
