  • Patent number: 5269045
    Abstract: An ergonomically adjustable handle for attachment to the body of a tool has a handle member with first and second ends with an axis between. Provision for attaching the first end of the handle to the tool body allows rotation of the handle about the axis through the attachment point. A pivot point is located on the axis of the handle member near the first end and permits deflection of the second end of the handle with respect to the first end. In addition, an outer layer portion of the handle member near the second end may be rotated about its axis to provide a comfortable position for the ellipsoidal cross section of the handle. Finally, clamping provisions at the articulation point and the two rotation mechanisms secure the handle in the desired position.

  • Patent number: 5225727
    Abstract: A modular reverse switch assembly having a rotating disc actuation member with a plurality of extending tabs which are spaced apart to project to opposite sides of the tool thereby permitting ease of operation by either hand. The modular design permits a wide degree of selection in assembly location and practice.
    Type: Grant

  • Patent number: 5017109
    Abstract: A pneumatic tool has a one-piece metal tube forming an air motor cylinder and an associated air inlet plenum. Air passages are formed between an inner housing, molded in situ about the motor cylinder tube, and an outer housing separately molded. The inner and outer housings are both formed from a non-metal composite material which contributes to operator comfort by its light weight, thermal insulation, vibration damping, and noise suppressing properties. The tool may be assembled to provide forward exhaust, rearward exhaust, or combined forward and rearward exhaust.

    Inventors: Gregory P. Albert, Kenneth J. Dubuque
  • Patent number: 4970920
    Abstract: The tool has a circular body, and an actuating lever pivotably coupled thereto. The lever, however, has two limbs, joined through a bight, and one of the limbs is fully nested in a recess formed therefor in the body. Consequently, one may grasp the tool about the body, whereat the one limb is nested, without turning the tool on, inadvertently. The other limb extends outwardly from the body, however, and by grasping the tool thereat, and depressing this other limb, the tool is turned on.

    Inventors: Gregory P. Albert, Kenneth J. Dubuque
  • Patent number: 4927114
    Abstract: A tilt valve cartridge for a pneumatic mechanism has a cylindrical housing having two open ends, an annular valve seat secured in one open end, a valve member in tiltable contact with the annular seat and having a valve stem which extends through the valve seat and protrudes from the end of the cylinder, a spring to hold the valve member in a normally closed relationship with the valve seat, a sealing element secured to the cylindrical housing on its exterior surface so as to seal the interface between the cartridge and the mechanism, and retention feature to capture the valve member and valve biasing spring within the cylindrical cartridge. The modular cartridge feature simplifies installation and replacement of the valve in the inlet air passage of the pneumatic mechanism.
