Abstract

A friction saw including a Nylon textile cord of a given length anchored to handle elements in the form of molded elongated bodies, at least one of which has a radial slot through which one end portion of the Nylon cord is assembled or disassembled. A resiliant clip enclosing the handle locks the cord in place.

Claims

1. A light weight flexible saw comprising a textile cord having a generally abrasive external surface between longitudinally opposite knotted ends, and handle elements on the textile cord in abutment with said knotted ends, said textile cord being made of Nylon filaments capable of cutting thermosetting plastic materials in frictional contact therewith by sawing, the textile cord being reciprocated as a saw blade by means of the handle element, at least one of the handle elements having a molded elongated body having a radial slot therein through which the textile cord is received in spaced relation to the knotted ends, said one of the handle elements including a resilient clip enclosing the elongated body to prevent disassembly of the textile cord through the radial slot.

2. A tool for cutting an object, including an elongated flexible line having longitudinally opposite end portions and formed from filaments presenting an outer frictional cutting surface with respect to said object, said line being adapted to frictionally contact a relatively inaccessible portion of the object from which the line extends in generally opposite directions toward the end portions, handle means in abutment with the end portions for transmitting pulling forces to the line in said opposite directions, and means independent of the end portions for enabling removal of at least one of the handle means from the line to permit threading thereof about the object into frictional contact with said inaccessible portion, said one of the handle means including a body through which the line extends from one of the end portions and a retainer fitted about the body, the removal enabling means including a slot in the body through which the line is radially withdrawn upon disassembly of the retainer.

3. A tool for cutting a thermosetting plastic object, including an elongated flexible line having longitudinally opposite knotted ends and formed from helical Nylon filaments presenting an outer frictional cutting surface with respect to a thermosetting plastic, said line being adapted to frictionally contact a relatively inaccessible portion of the plastic object from which the line extends in generally opposite directions toward the knotted ends, handle means in abutment with the knotted ends for transmitting pulling forces to the line in said opposite directions, and means independent of the knotted ends for enabling removal of at least one of the handle means from the line to permit threading thereof about the plastic object into frictional contact with said incessible portion, said one of the handle means including an elongated body through which the line extends from one of the knotted ends, a retainer sleeve fitted about said elongated body and a washer at one axial end of the elongated body between the knotted end and the retainer sleeve, the removal enabling means comprising a slit in the retainer sleeve and a longitudinal slot in the elongated body through which the line is radially withdrawn upon disassembly of the sleeve.
