Frame Saw

Abstract

A frame saw is described, comprising a reciprocating saw frame (3) which is guided via guide means (9, 15) along lateral guide rails (4) and which comprises a sash (5) with two stringers (6, 7) for clamping parallel saw-blades (8) which cut in only one lifting direction, and a slider-crank drive (2) which is connected with the reciprocating saw frame (3) via lateral pushrods (12) in the area of the stringer (6) closest to the same. In order to provide advantageous constructional conditions it is proposed that the two pushrods (12) of the slider-crank drive (2) act upon a common crossbeam (10) for receiving the sash (5) in the area of the two stringer (6, 7) which is closest to the slider-crank drive (2), that the crossbeam (10) rests with the help of guide means (15) on the lateral guide rails (4), and that the crossbeam (10) is held in a swivelable manner relative to its guide means (15) about an axle (16) perpendicular to the guide rails (4) and the crossbeam (10).
