UNITED STATES PATENT OFFICE.
JOHN F. DAMON, OF ROUKLAND, MASSACHUSETTS.
IMPROVEMENT IN SAW-TOOTH ADJUSTERS.
Specification forming part of Letters Patent No. 192,903, dated July 10, 1877; application filed May 28, 1877.
To all whom it may concern Be it known that 1, JOHN F. DAMON, of Rockland, in the county of Plymouth and State of Massachusetts, have invented a new and Improved Saw-Tooth Adjuster, of which the following is'a specification:
This invention has relation to devices for truing the ends of circular-saw teeth which are swaged; and the nature of my invention consists in a hand-tool constructed with a gage for determining the trueness of the cutting-edges of the teeth.
In the annexed drawings, Figure 1 is a front view of the adjuster. Fig. 2 is a longitudinal section of the same. Fig. 3 shows the file and straight-edge.
Similar letters of reference indicate corresponding parts.
The letter A designates the frame of the adjuster, which is constructed with graspingflanges B B. On one end of the frame A is a cross-bar, O, which serves as a straight-edge, and which is exactly at right angles to a plane touching the surfaces of two rests, on a consequently when the rests are upon a saw-blade,
and the straight-edge O is adjusted to the cutting-edge of a tooth, it will appear at a glance whether the edge is square or not.
If it is desired to have the edges ofthe teeth pitch a little laterally, the required pitch or bevel is determined by the adjusting-screw b, which will then rest upon the saw'blade.
adjusting-screw, 11, combined substantially as described.
JOHN FELTON DAMON.
