COMBINED SAW JOl-NTER AND GAGE.

sBncIFIcA'rroN forming part of Letters recent no. 690,668, dated January 7, 1902.

Application filed August 6, 1901.;

To aZZ whom it may concern:

Beit known that L-DAvID W. SOLOMON, a citizen of the United States, residing at Arlington, in the county of Snohomish and Stare 0f Washington, have 'invented certain new and useful Improvements in a Combined Saw Jointer'and Gage, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to saw jointers and gages particularly intended for use upon crosscut-saws.

The object of the invention is to provide such an implement of strong and simple construction where the several parts are accurately adjustable to suit the saw being operated upon to accomplish the desired results, and particularly to provide means for jointing the cutting-teeth of the saw to uniform lengths transversely of the saw and to a fair curve or arc of a circle longitudinally thereof, such means including the file-bearing supports and clamp adjustably mounted to the implement-stock,whereby the saw can be put into such perfect condition as to insure its running true or straight, a result unattainable by other saw-jointers now in use. This object is accomplishedin the construction and combination of parts hereinafter fully described and which is illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of the implement. Figs. 2 and 3 are respectively plan and end views thereof, and Fig. 4t is a crosssection on line 4 4 of Figs. 1 and 2. v

The body or stock a of the implement consists of a frame having a series Of horizontal laterally-projecting strips b and c integral with and disposed upon theopposite sides of lthe vertical web w thereof and faced so as to present a fiat surface on each side of .the web for the saw to bear against while being Operated upon. At the upper edge of the stock Y is a iiange d,which projects transversely from w are stationary, while the others, f, are vertically movable andformed of pins extending through holes provided and secured to any serial No. 71,044. N0 man.)

i set position by screws g inserted in threaded 1 apertures in the ends of the said fiange.

A filet is held against the said file-supports by a clamp havi u g a clam p-screw h,whi`ch extends through the clamp-yoke j and seats upon the top of the stock. The yoke straddles the iiange 'd and engages with the file by the inwardlyprojecting toesk, formed on the extremities of its pendent legs, overlapping and embracing the-same. As les are usually made tapering, the aforesaid clamp is positioned, preferably,

to one side ofthe mid-length of the stock, so that when the file is in the implement and tension put thereupon the file will be bent to a true arc of a circle and, to p rovide for saws of'different thickness in the blade-that is,A where they tapertoward their back edgethe file is inclined so as to bring the face thereof at right angles to the medium line of the sawblade when resting against the bearing-'strips b aforesaid, and that the strain upon the iile will be equally distributed upon its supporting-points, so as to prevent any twist of the file, I taper the bearing end Z of the clampscrew to allow a slight tilt or swing to the clamp to correspond with any change in the plane ofthe said supporting-points.

m is a pin protruding through a hole in the top of the stock and secured therein by a binding-screw n, so as to be adjustable for use as a gage-point when swaging the saw raker-teeth, the iile being removed during this operation and the cutting-teeth, which have been previously jointed, rest against face-plates o of hard steel.

After the raken-teeth have been swaged to the gage height the implement is reversed and the strips c brought to bear against the blade of the saw, so that the face-plates 1o will rest upon the cutting-teeth, and each of the rakerteeth is successively inserted in the oblong aperture r of the block s to be individually jointed by drawing a file thereacross.

What'I claim as new, and desire to secure by Letters Patent, is n l. In a device of the class described, in combination with a frame having a series of sawbearing strips disposed upon opposite sides of the web thereof, a iile-supporting ange extending along one of the longitudinal edges of said frame and projecting transversely outside of the plane of the said saw-bearing roo strips upon one side of the frame-web, an adjustable swage-gage extending through said flange, another flange disposed upon the opposite diagonal longitudinal edge to the aforesaid flange and extending transversely outside of the plane of the bearing-strips upon that side, a raker-tooth jointing-block having an oblong aperture extending therethrough attached to the last-named flange, and a file, of means to secure the said file to the said file-supporting Harige so that the file can be bent to an arc longitudinally of the frame and of the entire length thereof, and means Vto change the inclination or slant of the file transversely of the frame, such means including a clamp having a yoke which straddles the upper portion of the frame with inwardlyprojecting toes at the lower extremities thereof to overlap and engage the said file and a clamp-screw which extends through the yoke and bears upon the frame, and supports for said file positioned beneath the file-supporting flange adjacent to the ends thereof two of said supports being adjustable as to height, substantially as described.

2. In a device of the class described,in coinbination with a file, a frame having a series of saw-bearing strips disposed upon the web thereof, and a iiange extending along one of the longitudinal edges of said frame and projecting outside of the plane of the said bearing-strips transversely of the frame; of supports for said file comprising two fixed bearings and two adjustable bearings disposed, respectively,upon the inner and outer edges of the said flange and a clamp straddling the said fiange and adapted to dravT the vile against the said supports, substantially as and for the purposes set forth.

3. In a device of the class described, in combination with a frame and a tile, of'adjustable bearing-supports for said file comprising pins extending through a flange of said frame and binding-screws for securing said supports to any set position.

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

DAVID W. SOLOMON.
