Description
UNITED E. J. ROBINSON, OFOANTON, OHIO.
IMPROVEMENT IN SAWS.
Specilieation forming part of Letters Patent No. 58,297, dated Sepieinler 25, 1866.`
To all whom it may concern:
Be it4 known that I, E. J. ROBINSON, of Canton, in the county of Stark and State of Ohio, have invented certain newland useful Improvements in Saws; and I do hereby de Clare that the following is a full and complete description of the construction of the saine,
- blade in the ordinary way.
The teeth of this saw anenot constructed in the ordinary Way, being very long, asshown in the drawings, Fig. 2 beinggairenlargedsction of a partwoffthermsawlteeth, aidl'iigfa View looking on the edge otlthe teeth. "These teeth are filed from the pint'ctto MT As the saw passes from the' person using it the edge a plane had been used, and not tearing t-he wood like thc ordinar5 saws, the cutting-edges being on the side that the teeth are beveled on, every alternate one being .beveled on the same side, as shown. The other side of these teeth is plane and in line with the pla-te.
These saws need but very little or no setting, and will not get ont ot' order as easily, and will cut with more rapidity and ease, than the ordinary saws; neither do they require the amount of tiling and setting.
/Vhat I claim as my improvement, and desire to secure by Letters Patent, is-
A saw constructed with elongated teeth, in the manner described, for the purpose set forth.
E. J. ROBINSON.
