ABSTRACT:
A high speed short stroke saw for cutting plaster casts, bone and the like, is constructed to operate with minimal noise from the mechanism. The motor driven rotary shaft and the oscillating saw blade shaft are mounted in bearing support structures in a casing. The rotary motion of the motor shaft is translated to the oscillating motor of the saw blade by a bearing mounted cam that fits within a drive rod and receives the motor shaft. The drive rod is connected to a bearing mounted crank which receives the saw blade shaft. This entire mechanism is sealed in oil.
