Appl. No.:

7/382476

International Classification:

US Classification:

81 5713

Abstract:

A cordless powered ratchet wrench includes a ratchet actuator that selects a direction of rotation of an output shaft that is adapted to hold rotating tools for use. The ratchet actuator also serves as a ratcheting stop to permit a limited amount of ratcheting motion for manual tightening or loosening of a nut, bolt or the like. A lost-motion drive transmits power from a battery to the output shaft while permitting nearly two full circles of ratcheting rotation. An external pushbutton operates internal switches to connect a rechargeable battery in a desired direction, and also functions as an interlock to prevent reversal of the direction in which torque is applied while the pushbutton is engaged. The ratchet actuator that selects a desired direction of rotation also functions to provide a positive driving surface for manual exertion of torque by an operator and as a ratchet to permit rotation in the opposite direction when the wrench is ratcheting, and it operates a switch to select a direction of powered motion. Exposed terminals prepare the wrench to be inserted into a charger for recharging the battery.

Abstract:

A telephone hookswitch actuator and handset support assembly arranged to allow a telephone instrument to be used as either a desk or wall unit. The actuator is constructed of two independently pivoting members, a first hookswitch actuator member controlling the "on-hook" and "off-hook" switching and a second alternatively positionable support member. When the telephone instrument is intended to be used as a desk unit a retaining device manipulated from the exterior of the telephone is adjusted out of contact with the support member allowing the support member and actuator to act in unison. When used as a wall unit the retaining device is adjusted into contact with the support member which then retains the member outwardly extended allowing a cavity on the handset to accept the support member, supporting the handset.
