HENRY DISSTON, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN CROS'SCUT-SAW HANDLES.
Specification forming part of Letters Patent No. 179,282, dated June 27, 1876; application filed April 29, 1876.
To all whom it may concern:
Be it known that I, HENRY DISSTON, of Philadelphia, Pennsylvania, have invented an Improvement in Grosseut-Saw Handles, of which the following is a specification:
The object of my invention is to facilitate the manipulation of one-man crosscut-saws by providing the same with an additional handle, which can be adjusted on the blade to any position which the convenience of the operator may suggest.
in the accompanying drawing, Figure 1 is a side view of a one-man crosscut-saw with my improvement; Fig. 2, a side View of the supplementary handle, and Fig. 3 asectional View o'tthe same.
The handle consists of a metal clamp, A, secured to the wooden gripe B by a screw, a. The clamp has a slot, 1), adapted to the blade D, and two thumb-screws, d d, serve to bind the clamp securely to the said blade. The
saw is provided with the usual handle H, which the operator grasps with one hand, the other hand grasping the supplementary handle, which enables him to steady and control the saw, and to operate the same with better efi'eet than the single handle H, even if the latter be large enough for both hands.
The supplementary handle can be adjusted to any position 'on the blade which may be mostconvenientfor the operator, and secured after adjustment, or the handle may be entirely detached from the blade; or, should asecond operator be at hand to render aid in manipulating the saw, the supplementary handle can be clamped to the blade near the outer end of the same, as shownby dotted lines in Fig. 1-, when the saw can be used in the same manner as an ordinary two-man crosscut-saw.
I prefer to connect the gripe B to the clamp
