Abstract: A hand tool or grooving or cutting pipes has an aperture for receiving a portion of pipe, and adjustable support means. A cutting or grooving wheel is displaceable along a predetermined path to cause it to move radially relative to the pipe, as the tool is manually rotated round the pipe.

Abstract: The invention is directed to an electric shaving apparatus having a housing and a shaving head assembly which is adapted to pivot relative to the housing about a pivotal axis Z and is comprised of a shaving plane formed by at least one outer cutter having arcuate extensions to the longitudinal sides of the shaving head frame, and of at least one inner cutter operatively associated with the outer cutter and driven by a drive mechanism, wherein the inner cutter is coupled to the drive mechanism arranged in the housing by means of a coupling member in a manner permitting pivotal movement about the pivotal axis Z.

Abstract: A motor-driven hand circular saw, has a base plate, a motor, a drive housing surrounding the motor, a saw blade provided with saw teeth and being in operative connection with the motor, a saw blade housing accommodating the saw blade, an upwardly movable saw shaft having the saw blade, a hinge arranged so that the drive housing together with saw blade is movable upwardly and downwardly normal to the saw shaft with respect to the base plate for cutting depth adjustment. The saw blade is movable in and out. A turning hinge having a turning axis extends in a feed direction so that the saw blade housing is connected through the turning hinge with the base plate, and there is at least one upper and lower handle with respect to the base plate. The saw blade housing with the saw blade is located at the left and the drive housing is located at the right as considered in the feed direction. The hinge for cutting depth adjustment is arranged at the front side of the base plate as considered in the feed direction.

Abstract: The invention is directed to an electric shaving apparatus having a housing 1 and a shaving head 2 mounted so as to be pivotal relative to the housing 1 about a pivotal axis Z, having an outer cutter 36 and an inner cutter 31 operatively associated with the outer cutter 36 and driven by a motor, and further having an actuating switch 4 which is provided on the housing 1 and is equipped with a control device for displacing at least one slidably mounted control element 33 which engages in the pivot area 10 of the shaving head 2, limits the pivotal movement of the shaving head 2, and is guided along a cam path 13. The cam path 13 is integrally formed in the shaving head 2 such that, on displacement of the actuating switch 4 into an Off position, the shaving head 2 is forced into a mid-position in which it is capable of being locked.

Abstract: A small, hand-held tool for removing the outer sheath of plastic material covering a bundle of individually insulated electric conductors, with special capacity for the twisted surface of three-conductor non-metallic sheath cable. Important features of the tool include a short, dull, hook-shaped claw for safely effecting an opening in the side of the sheathing sufficient to admit the guide-shoe at the tip of the blade; a crescent-shaped blade for both slitting the sheathing and for chopping off the residue of slit sheathing; a thin, flat shoe with its broadest part near the leading edge; and a handle so shaped with gripping lobes and so positioned relative to the shoe as to offer a firm pulling grip while permitting the first finger and thumb to help position and guide the tool during the slitting operation.

Abstract: A detachable swivel grip arrangement (10) for knives (100) wherein the grip arrangement (10) includes a grip unit (11) an axle unit (12) and a detachable axle capturing unit (13) operatively connected with one another and releasably associated with the knife handle (102) to allow both reciprocating and rotating movement of the grip arrangement (10) relative to the knife (100) when the swivel grip arrangement is operatively displayed relative to the knife (100).

Abstract: A glass cutter having an upwardly inclined shank extending into a handle at one end for supporting the glass cutter with a cutter housing at the other end of the shank. A bulbous horn for cooperatively receiving the end of the index finger extends from the cutter housing at an angle to the shank for supporting and guiding the circular disk in the cutter head with the hand grip.

Abstract: A flat support member mounted on and extending above a horizontal worktable has an elongated, inclined slot therein with a rack formed along its upper side, a wheel lying along one side of the member and rolling on a workpiece on the table has a coaxial pinion gear of smaller diameter than the slot width fixed to one face thereof and loosely retained in the slot, horizontal movement of the workpiece in one direction moves the pinion horizontally out of engagement with the rack and causes rotation of wheel and pinion in one direction and movement of the workpiece in a reverse direction moves the pinion horizontally into engagement with the rack and causes rotation of the wheel and pinion in an opposite direction to apply downward pressure of the wheel on the workpiece.
