Abstract: A manual pipe cutter that comprises a cutting disk and a cutter-pressing jaw to press the cutting disk edgewise against a pipe to cut it, and is characterized by a pushbutton and gear arrangement for convenient operation and forceful pressing of the cutting disk edgewise against the pipe. This manual pipe cutter further comprises a body defining a cutting head portion and a handle portion, a cutting head rotatable in the cutting head portion of the body and cooperatively forming with it a pipe passage and an open mouth to position a pipe transversely into the pipe passage, a pawl and ratchet to rotate the cutting disk around the pipe, and means to release the movable jaw and return it to its outermost position.

Abstract: A tube cutter comprises an elongated handle formed in two longitudinal halves and having a C-shaped head at one end also formed into halves and defining an opening through which a tube can be inserted, a C-shaped body rotatably mounted within the two half portions of the head and comprising an opening of substantially the same width as the opening of the C-shaped head, a pawl and ratchet system formed at least between one of the contacting surfaces of the body with a half portion of the head, and a tube cutter assembly mounted on the body and including a tube cutter member mounted on the body, a tube abutment member slidably mounted in the body for radial movement towards and away from the cutter member, and control means mounted on the body to move the abutment member towards the cutter member to press a tube between the two members, such two members having a spacing therebetween in register with the openings of such body and head whereby a tube can be inserted through the registering openings in the body an

Abstract: A pipe cutter incorporating a ratchet handle. A tubular open-ended rigid body, adapted to surround the pipe to be cut, carries a cutting wheel and a jaw adjustable towards and away from the cutting wheel. An elongated handle has a ring member at one end rotatable within a peripheral groove of the tubular body. A pawl and ratchet system is arranged between the handle and the body, whereby back-and-forth rotation of the handle through a limited angle will cause step-by-step rotation of the body and cutter in one direction through at least 360.degree.. The body has a lateral opening which registers with the access opening between the jaw and the cutter. The ring of the handle also has a lateral opening which can register with the opening of the body in one angular position of the handle for the insertion of a pipe through the aligned openings in position within the body and between the jaw and the cutter.

Abstract: Lighted information panels located at the rear end of an automobile, arranged in two sets: one set lighting red to indicate to the following driver that the preceding driver has his high beam lights on and the other set lighting green to indicate to the following driver that the low beam lights are on and also capable of flashing to attract the attention of the following driver who will, in response, dim his high beam lights, so as to prevent blinding of the preceding driver.
