ABSTRACT:
An oscillatory saw wherein a motor is provided with an output shaft driving a multi-lobe cam having an uneven number of cam lobes in excess of two and wherein a pair of opposed cam followers engage the multi-lobe cam in such a manner that one of the followers may be adjacent to a lobe of the cam while the opposite cam follower bearing may be adjacent to an area of the cam between a pair of the cam lobes thereby providing for oscillatory motion of the cam followers and the saw blade connected thereto. The disclosure also relating to a novel arrangement of a cam follower yoke having opposed cam follower bearings and a saw blade pivoted on a common pivot with the yoke and having an arcuate row of openings into which a trunnion of the yoke fits so as to drive the blade. The disclosure also relating to means on the yoke for engaging teeth at the periphery of the blade for driving it. The disclosure also related to multi-lobe cams having an uneven number of lobes in accordance with the foregoing comprising cams having three, five and seven lobes respectively.
The disclosure being related specifically to oscillatory saws which are small, compact and operated at very high frequency and which are particularly adapted for use as cast cutters, bone saws and similar uses.
