A simplified fastening tool which uses the energy stored in a spring to install fasteners by an impact blow is disclosed. A housing body is preferably cast or molded. A one-piece plastic hand lever is pivotably attached to the body where the pivoting action is by sliding in a circular arcuate channel. A staple feeding track is slidably mounted to the bottom of the housing and includes a rear end element with forwardly extending resilient latching elements to secure the track. A hand grip opening...

A windshield wiper adaptor system that fits hook, bayonet and small and large pin wiper arm styles is disclosed. A bracket semi-permanently snap fits to a spring steel flat strip wiper frame. Adaptors fit to the bracket. The bayonet arm adaptor uses an easily molded slot to provide the detent for holding the arm. A resilient element presses the bayonet arm from below. The hook/bayonet adaptor pin, and pin arm adaptors, are held in the bracket by a barbed resilient arm attached to the pins. A fur...

A low profile, flexible windshield wiper assembly has a frame constructed from flat sheet spring steel. The frame attaches to a semi-rigid spline at distinct pressure points, while the spline supports a rubber wiping blade. At least some of the pressure points are located at the end of cantilevered fingers formed in the frame so that the spline may flex independently from the frame. The cantilevered fingers allow semi-pivotable portions of the frame to flex independently from the rest of the fra...

A manually powered fastening tool which stores and instantly releases the energy of a spring such that it may force a staple or other fastener into an object by an impact blow is disclosed. An actuating lever engages a plunger in an upward motion against a spring bias and in a sideways direction in a release motion. An arcing motion of the lever causes an element of the lever to rotate and slide rearward from the plunger and disengage from the plunger, thereby allowing the lever to slide sideway...

A manually powered fastening tool which stores and instantly releases the energy of a spring such that it may force a fastener into an object by an impact blow in which the operating handle is hinged near the end of the tool body opposite the end from which the staples exit. The main spring is a single piece flat torsion spring which decreases in cross-section away from its fulcrum point to enable the entire spring to provide energy storage. The operating handle is linked to the spring through a...

A self-forming socket having a plurality of retractable pins bundled in parallel within a housing is disclosed. The bundled pins may displace longitudinally and are biased by spring force away from a frame onto which the pins are slidably held. A spacer pin may be positioned at the center of the socket and is similarly biased away from the frame under spring force. When the socket is forced over a fastener, nut, or bolt head, groups of pins are pushed inward toward the frame and into the housing...

A stepless ratchet one way clutch mechanism, which provides an improved ratchet tool, is disclosed. A drive head is rotatably fitted into a cylindrical recess in a wrench housing. The drive head includes a partially triangular shape with three flat sides equally spaced around its circumference. A latch is positioned between each flat side and the internal wall of the recess. A selector mechanism provides a rotational bias to the three latches about the rotational axis of the drive head. The driv...

A call processing embodiment where customers are offered, in addition to the conventional office dialing plan, a special dialing plan where received numbers are processed such that a query of a database is defined when a prespecified access code, e.g., *66, is received, for example followed by a destination number, but where call blocking is defined for a predefined plurality of destination numbers, e.g., all destination numbers beginning with 976 or 1-900 or all destination numbers beginning wi...

A system for employing a computer to control a device to provide a plurality of services for a plurality of entities. Each entity corresponds to exactly one of the services and each service has its own copy of the code which defines the service. The system associates a process which executes the service with each service. The code for a service defines a finite state machine which is continually executed by the service's process. While in a given state, the finite state machine may traverse a de...
