  • Patent number: 7300043
    Abstract: A rotating positioning vise for use in hand working operations. The positioning mechanism utilizes a permanent magnet that is lifted off the surface of a turntable by the means of a lever. The user pushes on the lever, moves the vise in the position desired and then releases of the lever. Releasing the lever allows the magnet to be pulled back down against the turntable's surface and locks the vise in position.

  • Patent number: 6530435
    Abstract: An apparatus for a hand-held pneumatic impact tool for use in fine hand working operations includes a handpiece, a foot-operated flow control valve with exhaust and two hand operated flow control valves. The handpiece includes a housing having a cavity and annular shoulder accommodating a stepped piston dividing the cavity into three chambers. The control apparatus provides control for a hand-held pneumatic impact tool that will return an impacting handpiece to a fine oscillation idling state quickly when the user releases the foot-operated flow control valve. The apparatus also provides ease of control for adjusting the idling ready state of the handpiece to a faint oscillation idle.

  • Patent number: 6488102
    Abstract: A hand-held pneumatic impact tool for use in fine hand working operations includes a mechanism for adjusting impacting characteristics of the device that is conveniently located and adjusted by the user. The mechanism includes an annular band protruding around the outside diameter of the body of the impact tool that may be turned for adjusting an annular ring in the bore of the tool and thus altering the distance required for the piston to reach impact collision with the anvil. The impact tool also includes a handle containing a receiving-recess and a handle-attachment unit to permit manual removal and installation of the handle. The handle-attachment unit includes more than one protruding member positioned a distance into the receiving-recess, more than one groove on the outside diameter of body and running a distance and in a direction substantially parallel with the central longitudinal axis of the body and then changes direction and rotates around the central longitudinal axis of the body a distance.
