Abstract

630,801. Reciprocating saws. DEHN, S. G. (Orthopedic Frame Co.). March 31, 1947, No. 8676. [Class 145(ii)] In a reciprocating saw for cutting surgical casts, bones, wood, plastic or metal, an elongated casing 4 constituting a handle and a housing for a rotary shaft 7 carries a cutter head 11 at one end for supporting said shaft, and a cutter shaft 26 operatively connected to said rotary shaft to be oscillated by it, which cutter shaft is fitted with a toothed cutter 30 at right angles to the cutter shaft 26 and having its teeth disposed in an arcuate path about the said cutter. shaft. In the arrangement shown the shaft 7, preferably driven by an electric motor, is provided with a crank or eccentric pin 8 and a balancing arm 10, the pin having an anti-friction roller 9 mounted thereon. On rotation of the shaft 7 the roller 9 slidably moves in a slot 29 in the arm 27 attached by the pin 28 to the cutter shaft 26, thus oscillating the shaft 26 and circular cutter 30 to give the latter a stroke at its circumference of the order of one-eighth of an inch. The saw is said not to cut or injure yielding materials such as fabric or the skin.
