Abstract

163,904. Wieksteed, R. May 7, 1920. Reciprocating-saw machines.-The arm of a hack-saw frame has flat vertical sides D guided between facial portions of the framing and straps B with adjusting-nuts B<1>, having springs under them, to take up wear. The straps may be on one or other sides of the crank-pin G<1>, which drives the vertical lever H pivoted to the frame at H<1> and to the frame arm at H<2>. The work is held against the table A<5> by an arm J with a tightening-nut J<3>, and the saw is loaded by a weight K on a horizontal lever linked to the front end of the frame.
