PATENT OFFICE- WILLIAM M. STOVALL, or cLAL AM'BAx; wAsHiNe'roN.

B it known that I, WILLIAM M. SrovALL, a citizen of the United States, residing at Clallam Bay, in the'county oi Glallam and State of Washington, have invented certain new and useful Improvements in Saw-Sets, of which the following is a specification, reference being had therein to the accompanying drawings. This invention relate'sto a sawv set,fand has for its object the production of a relatively simple and eflicient saw set thatr'an be used tosetthe teeth of different kinds of saws. I

lVith this and other objects in view, my invention comprises certain novel construe-. tions, combinations, and arrangements of parts as willbe hereinafter specifically described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure l is a view in side elevation of my.

improved saw set. a Fig. 2 is a fragmentary sectional view of thesawset. p n

Fig. 3 is a fragmentary perspective view of the saw set showing ,an embodiment of the spring sheet-metal 'guide.

Referring to the drawings by numerals, 1 comprises the primary handle that is provided at its outer end with a right-angle extension 2, which extension 2 is provided at its outer end with a right-angle extension 3,

' and the extension 3 is provided at its outer end with an inwardly-extending extension t parallel with the extension 2; the extension 4 is provided at its outer end with an inwardly-extending lip 5 that engages the saw teeth or blade when the saw set is in position upon the same.

A bar 6, constituting an extension, is. proyided with an inner threaded end '7, which end 7 extends through aperture 8 'in the handle 1, and upon opposite sides of. the

' handle, and threaded upon end 7 are look and an inner .shoulder-portion-.13, formed upon its inner end, and a limiting bolt .14 isthreaded through the bar, 6, near .its outer end, and the inner end of bolt 14: engages shoulder 13 of handle 11 forlimiting the in v Specificationof Letters Patent. Pat ented'J l 12 1921 Application filedlMarch 5, 1920; Serial No. 363,615.

Ward swinging movement of the handle upon itszpivot 10, which limiting movement also limits the inward pressing movement of the handle '11 upon the set rod 15.-

The set; rod 15 is freely slidable in the elongated aperture 16 formed in bar 6, and the-rod is also freely slidable inthe elongatedaperture 17 formed in the extension 2; these apertures 16 and 17 register, and permit the bar to be bodily adjustable longitudinally of the bar 6 and extension 2, by means of the adjusting bolt 18. When the adjustmg bolt 18 is rotated inwardly, it will push the set'rod l5 bodily toward the handle 1.. and thereby permit the'bar to' operate on different sized teeth, with excellent results. A fixed collar 19 is mounted upon rod 15. and a sli'dable collar 20 is also mounted upon rod 15, and between the collars 19 and 20 is positioned a coil spring 21. This spring normally holds the set-rod 15 in its seated position, shown in. Figs. 1 and 2, bearing against the shoulder 12 of handle 11.

The bolt 22 is threaded upwardly or outwardly through the extension 2, and its inner end is adapted to bear. against the teeth of the saw being operated upon, for keeping the tooth from being bent back.

' On opposite sides of the outer extension 1 are positioned screws 23, and these screws are used tofretain the spring sheet-metal guides 24; (Fig.1) or 25 (Fig. 3) upon the extension 1; The guide 24 is provided with a body portion 26 resting flat against the side of the extension 1, and in the body :26 is formed an elongated slot 27 for permitting adjustment of the guide upon the screw 23. wardly at 28, and the extreme lower or inner end 29 of the guide is formed straight to engage the blade. In the embodiment shown in Fig. 3, the flat body portion 26 Tests against-the side of the extension 1, and the press upward or inward upon the set rod 15 tov cause the inner end of said rod to bend Thebody 26 of the guide is bent ou'tp manually-operated movably mounted upon said saw-receiving" the tooth being operated upon; however, limiting bolt 14 will prevent too great a movement of the set rod, and ass'oon as the'operator has released the auxiliary handle 11,

spring 21 will cause the collar 19 to be seat ed upon the bar 6, relievingpressure of the tooth. 7

While I have described the preferred forms of my invention, and have illustrated the same'in. the acc'ompanying'drawings, I

may find certain alterations or'changes necessary in therextensive manufacture of-my saw set, and, therefore, I reserve the right to make such minor alterations or changesas shall occur to one skilled in the art to which this invention relates, and-which alterations or changes fall within the scope of the ap pendedclaims. What I claim is: 1. In a saw set, the combination of a handle provided with asa u' -re'ceiving end,

a bar provided" witlran inwardly-threaded' end extending through the hand e, locking nuts. atopposite sides of the handle and mountediupon the threaded end of the bar for holding the barsecurely upon the handle, tooth-bending means on" the sawreceiving end and on saidbar, and an aux-' iliary' handle movably mounted on the bar and cooperating with the tooth-bending means for actuating the same at the-will of the operator; I

2-. In a saw set, the combinationof a handle'provided witha saw-receivingend,

tooth-bending: means oarriedby said sawreceiving end-means for operating said tooth-bending means, spring sheet-metal guide positioned against said saw-receiving end, said guide provided with an inner apert'ured body having an outwardly 'bent portion, and said outwardly-bent portion-integralwith a straight saw-engaging-end for holding the same upon the saw-receiving end. i7 V 3. In a saw set, the combination of a handle provided with a saw-receiving end, tooth-bending means end, asheet-Inetal guide engaging said sawreceivrng end, sald guide comprising an innor flat end provided with an outwardly-r curved intermediate portion and with a straightouter end adapted tofengage a saw, and fastening means extendingthrough the inner end of the guide and securing the;

same to the side of the saw-receiving end.
