International ClassF16H 033/20AbstractAn orbital reciprocating saw comprising a housing, a motor, a spindle movably supported within said housing and having a front end adapted to support a saw blade, a reciprocating drive assembly, an orbital drive assembly connected to said spindle to selectively drive the saw blade in an orbital path, an orbital adjustment assembly connected to the orbital drive assembly to adjust the orbital path of the saw blade, and an adjustable shoe assembly. The orbital drive assembly includes an eccentric cam member removably supported on the motor drive shaft and engageable with the spindle to cause orbital movement of the saw blade upon rotation of the motor drive shaft. The orbital adjustment assembly selectively disengages the spindle from the cam member during at least a portion of the rotation of the cam member to change the orbital path of the saw blade. The adjustable shoe assembly includes a shoe, a shoe support member pivotally supporting the shoe, a locking member pivotally supported by the housing, and a lever connected to the locking member.Field of SearchReciprocating bladeWith blade-moving means With means to reciprocate saw In uniplanar compound path Including connecting rod articulated with saw blade or support With motor With motor Crank or cam, pitman and lever Crank or cam and lever Crank or cam and slide Wabbler type Cylinders parallel to rotation axis Shaft axis parallel to axes of working members (70) THREE OR MORE CYLINDERS ARRANGED IN PARALLEL, RADIAL, OR CONICAL RELATIONSHIP WITH ROTARY TRANSMISSION AXIS Assembly Separable ball retaining member Lock ring | |
