Apparatus for sawing different materials

In apparatus for sawing different kinds of materials, the improvement comprising in combination:

• a supporting frame;
• a supporting platform for material to be cut displaceable in said supporting frame;
• a reciprocating saw blade slanted at a free end for a length corresponding to a return stroke of said blade, so that said blade diminishes in width toward said free end;
• a roller positioned at said free end in a cutting plane, and at a back side, of the saw blade, and having an axle mounted in the supporting frame and extending transversely to said cutting plane;
• a spring acting on said free end of the saw blade and being connected to the supporting frame for pressing of the saw blade against said roller;
• and
• means for articulately mounting the saw blade at a second end opposite said free end.

In apparatus for sawing different kinds of materials, the improvement comprising in combination:

• a supporting frame including a girder-type construction defining an opening for the feedthrough of materials to be cut in longitudinal direction;
• a supporting platform for materials to be cut including a carriage displaceable in longitudinal direction;
• a clamping arrangement for materials to be cut on the carriage;
• a reciprocating saw blade mounted in said supporting frame and slanted at a free end for a length corresponding to a return stroke of said blade, so that said blade diminishes in width toward said free end;
• supporting bracket means positioned laterally of the saw blade in front and back regions of the frame and mounted on said carriage;
• an upper and lower cross-beam for each supporting bracket, with each lower cross-beam being arranged at a distance from the carriage platform;
• vertically movable rods arranged between the upper and lower cross-beams and carrying a clamping device for materials to be cut;
• a roller positioned at said free end of the saw blade in a cutting plane, and at a back side, of the saw blade, and having an axle mounted in the supporting frame and extending transversely to said cutting plane;
• a spring acting on said free end of the saw blade and being connected to the supporting frame for pressing of the saw blade against said roller;
• and
• means for articulately mounting the saw blade at a second end opposite said free end.
