Abstract: A switch for controlling the current to an electric motor is disclosed. The switch includes first and second parts which are relatively rotatable about a first axis. The switch also includes contacts which are actuatable to permit electrical power to be applied to the motor in a direction depending upon the direction of relative rotation between the first and second parts. A portion of the contacts are carried by a rocker arm pivotally mounted against one of the parts with cooperating contacts mounted to the one part. Actuation of the contacts is controlled by an associated pivoting member located radially outward of the first axis and pivotable about a second axis, transversely to the first axis. The pivoting member carries a roller slidably mounted to an end thereof and resiliently biased against the rocker arm. The roller is of sufficient diameter to contact the rocker arm at two locations when the switch is in a neutral condition with all of the electrical contacts open.

Abstract: A fastener assembly of the nut and washer type includes a washer member having a skirt portion and an end portion to which a nut member is secured. A collar section connects the skirt portion to the end portion. The collar section is designed to fracture at a predetermined torque load such that the nut and the end portion of the washer secured thereto will rotate with respect to the skirt portion.

Abstract: A system to facilitate installation of push-in type fasteners including apparatus to feed fasteners to an escapement unit and a manually actuable hand tool to take the fasteners from the escapement unit and insert them in a workpiece. The apparatus includes a vibratory bowl feeder for providing a continuous supply of fasteners to a track member extending between the vibratory bowl feeder and the escapement unit. The escapement unit aligns a first fastener for receipt in the fastener inserting tool, positions a second fastener for subsequent alignment, and limits advancement of the second fastener until the first fastener has been removed from the escapement unit. The fastener inserting tool comprises an outer housing or handle that carries a press rod and an outwardly biased insert body. The insert body has fastener grasping jaws at one end.

Abstract: A fastener clip adapted for use with an associated fastener includes a head portion having an aperture through which the fastener extends. A pair of integral, spaced apart legs extend from one side of the head portion. Each leg includes first and second portions with the second portion being bent back upon the first portion in a position spaced outwardly thereof. A finger portion is located at a free end of the second portion and extends inwardly toward and through an aperture in the first portion. When a tension load is imposed on the clip, connecting zones between the first and second portions of each leg are deflected toward each other to apply a clamping force to a fastener extending therebetween. Also, the finger portions are shifted to positions which enhance seating of the clip in an associated workpiece.

Abstract: A two-part panel fastener comprises a socket member and a stud member. The socket member includes a base, an elongated retaining head supported above one side of the base, a receptacle defining a central bore extending from the opposite side of the base, a lip which constricts the opening to the bore, and a frusto-conically shaped flange extending from the end of the receptacle and having a concave surface facing away from the base and surrounding the opening to the bore. The elongated retaining head is adapted to pass through an elongated or "double-D" shaped aperture in a first panel and to be retained relative to the first panel when the head is turned a quarter-turn.
