ABSTRACT:
A scroll saw is disclosed as having a saw blade connected between the free ends of the arms of a C-shaped member. The C-shaped members is reciprocated about a horizontal pivot shaft at the closed or yoke end of the C-shaped member in order to reciprocate or drive the saw blade. An automatic bearing adjustment mechanism is provided for the horizontal pivot shaft that reciprocates the C-shaped member. For this purpose, an outwardly directed resilient force is applied against one of two bearings at opposite ends of the horizontal pivot shaft, the resilient force also applying an inwardly directed force through the horizontal pivot shaft to the other bearing, in order to eliminate any bearing play during operation and use of the scroll saw.
