'IMPROVEMENT IN SAW-SET.

TO ALL WHOM'IT MAY CONCERN:-
Be it known that I, 4JAMES F. BRODHEAD, of Rondout, in the county of Ulster, and State of New York,
have invented a new and improved Saw-Set; and I do hereby declare that the following is a `full, clear, and exact description thereof,`which'will enable those skilled in the art to make and use the same, reference being had in lhs accompanying drawings, forming part of this specification.
This invention relates to a. new and improved methodof constructing machines for setting'saws; andnthc invention consists in the general construction and arrangement of parts, whereby the article is rendered not only durable, and notl liable to get out of order, but most effective in Yits operation. The drawing- Figure 1, represents a longitudinal sectionfof the, machine.r showing the parts of which it is composed, and the manner of their arrangement. Y
Figure 2'is a; detched view of the regulating-nut.
Similar letters of reference indicate corresponding parts.
Thismachi'ne is So constructed, .that in using it for the purpose intended, a lever-purchase is brought to bear upon a. wedge, which action forces the end of a. sliding han towards the head of the machine, 'thereby gri- `ping the saw-tooth between the two.
A represents the handle'or tail of theilnachin'e. B is the lever. is the body of the machine, which containsY and supports the `operating parte. -D is the wedge. E is the sliding bar, the lower end of' which, with the lower portion of the body, seen atjgformsa. double-inclined plane', between which the wedge is operated. VThe fulcrum of the lever B is at H.' J isla' spring, which is lsecuredvin the body C, the end'of which spring engages with the sliding bar E, as seen in the drawing, and the adjustment is such that the tension of the spring forces the bar towards the wedge, while the action of the lever-B, when drawn towards A, forces the bar the other way. The redV lines represent the saw, withv the' tooth griped between the end of this bar and the head of the machin@ iis a. block of hardened steel, fixed inthe head of the machine, as seen in the drawing. K is a guide-screw, by which the amount of set to be 'given the tooth is regulated. L is a sliding-screw gauge, which is regulated by the nut m, by which the dept-1T ofthe set itz-determined.
The operating parts ofthe machine, 'as seen in Vthe drawing, are covered by a plute, so that they are conned in a. closed lrecess. The screw which confines the plate passes through the hole marked n in the body C of theA machine. This machin'eiis made of malleable ,or other suitable casting, combined with steel, in such a. manner as'will insure its durabilitypand eiciency. I
Having thus described my invention, I claim as'new, and desir-,ete secure by LettersA Patent- Thel wedge D, in combination with the sliding bai` E, plete C, handleA B, and gauge-screw L, all -rranged as described for the purpose specified.
