UNITED STATES PATENT OFFICE.
JAMES E. EMERSON, OF BEAVER FALLS, PENNSYLVANIA.
IMPROVEMENT IN SAW-TEETH.
Specilication forming part of Letters Patent No. l 51,371, dated May 26, 1874; application filed April 22, 1874.
CASE A.
To all whom lt may concern:
Be it known that I, JAMES E. EMERSON, of Beaver Falls, in the county of Beaver, in the State of Pennsylvania, have made certain linproveinents in Removable and Exchangeable Saw-Teeth for Saws for Sawing Stone, of which the following is a specification:
The object ot this invention is to produce a saw-tooth for sawing` stone, that when once dnlled or worn away by use a new set of teeth can be inserted in the sawplate in less time and at much less cost than the dull ones could be sharpened; and it consists in a steel tooth, in the form shown, as an article of inanufacture.
as the hammer or drop-die leaves it.
This tooth 5 is ina-de from apiece of the best steel cnt from a bar or wire ofthe proper form to avoid waste in material. rlhe piece is heated and subjected to a blow from a drop-hammer or die to form it into the shape seen in Figs. 2 and 3, to wit, to have the circular cutting'- edge X wider than the thickness of the sawplate and the tang,` 5', by which the tooth is held in place in the clamp 3 3, with the inner end of the tang abuttingl against shoulders in the clamp 3 3, as seen in Fig. 1. After the forming the tooth by trimming,` oft' the 1in left by the dropdie or hammer, by a finishing-die or other process, into a perfect shape, it is subjected to a process of tempering to give it the requisite hardness and toughness.
Having thus described my invention, what I claim is The tempered steel saw-tooth 5, herein` described, as a new article of manufacture.
JAMES E. EMERSON.
