IMPROVEMENT IN SAW-SWAGES.

Specification forming part of Letters Patent No. 153,!')S4, dated August 11, 1874,' application led July 1e, 18774.

To all whom it may concern Be it known that I, ALONZO G. RoUsE, of Jacksonville, in the county of Duval and State of Florida, have invented a new and useful Improvement in Swage for Saw-Teeth, of which the following is a specification:

Figure lis a side View of myimproved swage. Fig. 2 is a face view of the same. Fig. 3 is a side and edge view of a saw-tooth after the iirst operation. Fig. 4 is a side and edge view of a saw-tooth after the second or finishing operation.

Similar letters of reference indicate correspondin g parts.

My invention has for its object to furnish an improved swage for saw-teeth, simple in construction, effective in operation, and convenient in use, itsiapplication, it being self-adjusting to the teeth, and bringing the teeth into such a condition that they need very little finishing with the file. The invention consists in an improved swage for saw-teeth, formed by the combination with the recessed end ofthe stock ofthe round pin and the pin made with. one flat side, as hereinafter fully described.

|`A lrepresents the handle or stock of the swage, which is made of steel or other suitable material. One end of the stock A has a recess, a', formed in it, with straight sides, and one or both of its ends inclined or daring. Through the stock A, at the bottom of the recess a', are passed two transverse pins, B C, which are inserted inholes through the said stock. The pins B C are made of steel, and one of them, as B, may be perfectly round. The other pin, G, is made with one flat side,

and is so arranged that the said lat side may be at such an angle with the inclined end of requiring very little skill in.

vlittle finishing with the the recess a' as the inclination or taper of the tooth may require. The pin C is secured in position, when inserted in the stock A, by a key, c,^which is inserted ina groove in the said pin C, and in the said stock A, as shown in Fig. l. y

In using the swage, it is placed upon a sawtooth, with the point of said tooth between the pins B C, and one or more blows with a hammer upon the end of the stockA will cause the said'I pins to form small transverse grooves in the upper and lower sides or edges of the tooth, an eighth of an inch, more or less, from its point, the said point being unaffected. The swage is then adjusted to bring the point of' the tooth between the inclined side of the pin C and the inclined end ofthe recess a', and one' or more blows of a hammer upon the .end`

of the stock A will bring the point of said tooth to the proper form, bringing the corners out fully and squarely, obliteratng the grooves formed by the pins B C, and finishing the point of the tooth so perfectly that it requires very le. The lower end ofthe stock A may be strengthened, if desired, by a metallic band driven or shrunk upon it.

v Having thus described my invention, I claim as new and desire to secure by Letters Patent An improved swage for saw-teeth, formed by the combination with the recessed end of the stock Aof the round pin B and the pin C, made with one Hat side, substantially as herein shown and described.
