Abstract

The fret saw has a U shaped frame with cylindrical sockets on the ends of the arms. Jaws grip the ends of the blades and have threaded extension shafts which pass through the sockets and receive a handle or a wing nut. To prevent rotation of the jaws once they have been set each arm of the frame carries a sliding sleeve which has a lower extension abutting a face of the polygonal section end of its respective pair of jaws. Compression springs extend between the sleeves and studs threading into the arms of the frame; the sleeves having slots which receive similar studs which are used to lock the sleeves in position, the system allowing a simple blade locking to be achieved.
