Abstract: An improvement in a ratcheting driver of the type having a handle, a driver head connected to the handle, a driver stem, ratchet means contained in the head and including ratcheting direction selector means disposed on the head in axial alignment with and remote from the driver stem and operable to lock the driver stem against rotation in a direction which is preselected by the user by the limited rotation of the ratcheting direction selector means in a predetermined direction, consisting of a ratcheting direction control wheel disposed on the head in axial alignment with and remote from the driver stem and fixed to the ratchet means, and a control wheel cover disposed over the control wheel so as to be separated from the head thereby and locked to the head.

Abstract: A ratcheting adjustable wrench having an elongated handle and having jaw means, including a fixed first jaw element and a movable second jaw element, attached to one end of the handle, with means for selectively manually initiating longitudinal relative movement between the first jaw element and the second jaw element comprising a threaded drive member axially aligned with the second jaw element and disposed between the second jaw element and the handle, and a complementarily threaded driven member fixed to said second jaw element and extending through the drive member, a bias spring disposed between the drive member and the handle first end and operable to normally urge the drive member and so the second jaw element toward the first jaw element, and ratcheting means operable in response to torque applied to the handle in a selected first direction to longitudinally fix the first and second jaw elements with respect to a fastener clamped therebetween, whereby said first direction torque is applied to the fast

Abstract: An adjustable wrench utilizes a drive member housed in a wrench body. The drive member has a cylindrical drive element having external male threads formed thereon, onto which a guide block is mounted by means of a bore, within which female threads, complementary to the male threads, are formed extending longitudinally through the guide block, so that the drive element extends through the bore with the male and female threads in engagement with one another, whereby rotation of the drive element is operable to move the guide block longitudinally along the drive element. A drive knob is fixed to and manually operable for selectively rotating the drive element. A pair of alignment arms connect a movable jaw element to the guide block so that the movable jaw element faces and is displaced from the drive block in longitudinal alignment with the bore and is separated from the drive knob by the drive block.

Abstract: A linear driver has a drive stem having a first end and a second end and a handle fixed the drive stem so that the drive stem first end extends into a first end of the handle. In order to increase the torque the user may apply to the driver, the driver includes a thumb plate fixed when in its operating position with respect to the drive stem so that the thumb plate extends radially outwardly from the handle at the handle first end so as to permit its engagement by the thumb of a user. The thumb plate may be selectively retractable into the handle when not in use in certain embodiments of the invention, while, in others, the thumb plate remains fixed in its operating position.

Abstract: The present invention discloses a method for providing balanced power to a single-phase ac load from a three-phase ac power source. The method includes imposing an isolation power transformer between the ac power source and the load wherein the isolation transformer has a three-phase primary winding and a six-phase "wye" connected secondary winding, at least one of the three legs of the secondary having a center tap and being connected to the load such that the center tap provides a reference potential for the load and the reactive load currents are equal and inversely-phased with respect to the reference potential.

Abstract: A service jack includes a mirror attached to the jack's lift arm adjacent the jack's saddle so as to be able to provide a continuous reflected image for the jack operator as the lift arm is moved from its lowered position to its raised position of the sector of space above the saddle which includes a selected lift point for a vehicle being raised. A method for utilizing a service jack of this type includes the steps of positioning the jack with the lift arm in its lowered position adjacent the vehicle in the vicinity of the selected lift point, locating the selected lift point as a reflected image in the mirror, and moving the jack while elevating the lift arm so as to maintain the selected lift point as a reflected image in the mirror until the saddle engages the selected lift point.

Abstract: A tassel for use with venetian blind cords and chains has a generally bell-shaped hollow cap adapted to permit the passage of the cord or chain therethrough and a depending lip formed around the open end thereof with an internal annular recess formed thereon, and a receiver, adapted to be contained within the cap and adapted to permit the passage thereinto of said chain or cord and having a keyhole-type aperture extending radially across the closed receiver bottom and a peripheral lip formed thereon and adapted to lock into the cap annular recess. The cap and receiver are assembled by pressing the receiver into the hollow interior of the cap until receiver peripheral lip snaps into the cap annular recess.
