Abstract

3536. Heyn, J. Feb. 12. Sawing. -Relates to the construction of reciprocating saws with sets of teeth set at a slight angle to one another, to enable the saw to cut in both directions. In Fig. 5, one form is shown, where the line n o of one set of teeth is not in the same straight line with line o p of the other set of teeth. The set of teeth which is not cutting is thus kept clear of the wood. A gap v w is left between the two sets of teeth, to facilitate the discharge of sawdust. In a modification, the points of the two sets of teeth lie on the circumference of a circle.
