RICHARD BENNETT, OF RACKET LAKE, NEW YORK.

sAw-TooLf/f .SPECIFICATION forming part of Letters Patent No. 569,993, dated October 27, 1896.

Application met June 15. 1896.

To all whom it may concer/t:V

Be it known that I, RICHARD BENNETT, a citizen of the United States, residing at Racket Lake, in the county of Hamilton and State of New York, have invented certain new and useful Improvements in Saw-Tools; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in saw-tools, and it has for its object the provision in a single element of a saw-jointer, side dresser, and setting-tool, by the use of which it will be possible to perfectly set the teeth of a saw and to cut off the side edges of the teeth after the same has been set.

To these ends and to such others as the invention may pertain the same consists in the peculiar construction of the combinationtool, all as hereinafter described, shown in the accompanying drawings, and then speciiically dened in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a perspective view of my improved combination tool with the setting member shown as swung open or to one side. Fig. 2 is a side elevation of the tool as applied to a saw in the position required in jointing the tips of the cleaner-teeth. Fig. 8 is a side elevation of the tool as it appears while holding a file in position for dressing a saw-tooth.

Reference now being had to the details of the drawings by letter, A designates the stock or body portion oi' the tool, having formed in one of its side faces a depression or recess A', which recess extends longitudinally from one end of the stock to a point adjacent to the longitudinal center of the same, where is located the racker tooth-gage, which will be hereinafter described. The recess A is designed to receive and hold a le, and is of a depth slightly greater4 than the thickness of Serial No. 595,680. (No model.)

the file used, so that when the file is placed within the recess the outer or exposed cutting-face of the file will extend slightly beyond the outer side face of the stock. The recess is made to conform to the shape of the file; that is to say, it has a uniform andA gradual taper from end to end, being of the greatest width at the end of the stock. The depth is greatest at the end of the stock and the depth decreases uniformly as the opposite or inner end of the recess is approached.

It will be seen that when a file is placed wit-hin the recess and secured therein by the set-screw b, which is passed through a screwthreaded opening in the side edge of the stock and engages Ithe edge of the file, the iile will be held firmly within the recess with the cutting face of the tile at the angle with reference to the face of the stock which may be found to produce the best results in use.

The le when properly adjusted within the recesses A is used in side-dressing the sawteeth, in accomplishing which the tool is held in such position as to bring the at exposed face of the file into contact with the blade of the saw, so as to act upon the side edges of the teeth, as will be readily understood.

The portion of the tool which is designed to retain the iile in position to best adapt it for use in jointing the ends of the cleanerteeth consists of a groove a, which is designed to receive the file when turned edgewise. This groove a., while of a uniform depth throughout its entire length, is of greatest width at the end of the stock A, so that when a le is placed within the said recess it may be adjusted within the recess so as to conform with the line of curvature of the teethof the saw, as will be readily understood. To secure the proper adjustment and also to retain the file in its proper adjusted position, the set-screw b is employed.

Mounted on a screw-threaded pin C is the racker tooth-gage D, which has a slit cl out from its free end on one side of the stock of the tool, and the upright portion of the member D is vertically adjustable in a recess in the stock, the threaded nut E being turned either to the right or to the left, according as to whether it may be desired to raise or lower the gage.

IOO

When it is desired to set the teeth of a saw, the setting member F is closed. The edge of the stock beneath the notched end of the setting member is placed against the side of the saw with the fiat or the V-shaped portion of the set, as the case may be, resting on the tooth to be set. A blow with a mallet is then imparted to the upper end ofthe setting inember.

Then it is desired to use the tool as a common hammer-set, one of the flat faces of the stock is beveled so as to permit the saw to be placed thereon with the teeth projecting over said bevel. In Fig. 1 of the drawings the narrow edge, as shown at K, is for this purpose, but it may also be used upon a iiat side or face of the stock.

From the foregoing description, in connection with the illustrations of the device shown in the accompanying drawings, the various uses to which the tool is adapted will be read- 'ily understood, the essential object of the in- I claim to be new, and desire to secure by Letters Patent, is

The herein-described combination-tool the same comprising a stock or body portion having one of its faces provided with a tapering recess or depression A' within which a file may be adj ustably seated, a set-screw for adjusting and securing the file in said recess, an independent narrow and tapering recess CL within which the file is adjusted and held in position for convenient use in jointing sawteeth, a racker tooth-gage D vertically adjustable within a dovetailed recess in the stock as described, means for vertically adj usting the gage-block, and the swinging setting member F, pivoted at a point adjacent to one of its ends to the stock, and havingits opposite end notched as described substan- Tialiy as described and for the purpose specified.

In testimony whereof I aflix my signature in presence of two witnesses.

RICHARD BENNETT. Vitnesses:
