JASPER CLARK, OF LA PORTE, PENNSYLVANIA, ASSIGNOR TO CYNTHIA J. CLARK, OF SAME PLACE.
SAW-TO OTH SWAG E.
SPECIFICATION forming part of Letters Patent No. 226,977, dated April 27, 1880.
Application filed September 10, 1879. y
To all whom it may concern:
Be it known that I, JASPER CLARK, of La Porte borough, in the county of Sullivan and State of Pennsylvania, have invented certain new and useful Improvements in Saw-Tooth Swages, of which the following i`s a specification.
This invention relates to certain new and useful improvements in swages for Vsharpen- Io ing sawteeth 5 and the invention consists in a novel construction and combination of parts, all as will be hereinafter fully described, and specitically pointed out in the claim.
To enable others skilled in the art to which my invention is most nearly connected to make and use the same, I will now proceed to describe its construction and operation, refer ring for illustration to the accompanying drawings, forming a part of this specification, and
zo in which- Figure lis a perspective view of a device embodying my invention. Figs. 2, 3, 4, 5, 6, and 7 represent the different parts composing the instrument.
In the drawings, A represents the stock, composed of a piece of hardened steel; B, a collar iitting around the stock A, for holding the dies or plates E E and the small liners F F in position. The stock A under the collar 3o B is cut away or beveled off, as shown at H in Fig. 7.
C represents a lever attached to the collar B, which is used as a clamp for the purpose of holding the instrument firmly and steadily 3 5 upon the saw and the saw-plate firmly against the lower portion of the stock A.
D represents a steel spring for the purpose f of throwing the clamping-lever open when it is desired to remove the instrument from the 4o Saw.
The dies or plates E E are made of hardened steel, with one corner of either end beveled off, so that when placed togetherthey form a notch coming to a fine point, the shape of the point of a saw-tooth, this beveled notch coming next to the beveled face of the stock A. These dies or plates swage and sharpen the tooth when driven upon it.
The liners F are small thin strips of steel or iron, and are placed under the collar B above the dies or plates E. The position of the dies upon the beveled part of the stock A can be regulated by putting in or taking out said liners, and the depth to which the teeth of the saw require to be swaged and sharpened is thereby varied. Thus, if the teeth require to be swaged or sharpened to a considerable depth, these liners are taken out and the dies or plates moved up on the beveled face of the stock, while if very little is desired the liners are put in and the dies or plates moved down.
G represents a key or wedge for the purpose of holding the collar in piace and enablin git to be readily removed for changing the dies or plates and liners.
The operation of the device is as follows: Set the instrument upon the saw so that the point of the tooth shall enter the lower notch ofthe dies or plates. Then press down the lever C so that its lower part presses against the saw-plate, thus holding it firmly against the stock. Then strike the stock upon the top a blow with a hammer, when the tooth `will be swaged and sharpened.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
The combination, with the stock A, holder B, and intermediate dies or plates E E, of the clamping-lever C and spring D, substantially as and for the purpose herein shown and described.
JASPER CLARK.
