GAGE FOR CROSSGUT-SAWS.

Specicaton of Letters Patent.

Patented April 6, 1909.

Application led September 9, 1907. Serial No. 392,057.

To all whom it 'may concern:

Be it known that I, WILLIAM M.. E LwooD, a citizen of the United States of A1' erica, and a resident ofthe city of Seattle, in t ie county of King and State of Washington, have invented certain new and useful Improvements in Gages for Cros'scut-Saws, of which the fol` lowing is a specification.

My invention has for its primary object gage of the above type, through the medium of which the several o era'tions of top jointing, swaging of the ra er-teeth and side filing of the cutting teeth can be carried on in anefficient manner, with a minimum amount of labor and expense.

A further object resides in the provision of an improvement of this character which is comparatively simple in construction, and inexpensive to manufacture.

With the above and other equally desirable objects in view, to be referred to as the description progresses, the invention resides in the structural features, arrangement and hereinafter described combinations A,of parts in the appended and 'succinctly defined claims.

Referring now to the accompanying drawing in which like numerals of reference indi cate like parts throughout the several views: Figure 1 is a view in front elevation of my improved saw set. Fig. 2 is a bottom plan view thereof., Fig. 3 is a view similar to Fig. 1, but showing the opposite side of the inven tion, and Fig. 4 is a sectional view taken on line 4-4 of Fig. 1, and, Fig. 5 is an elevation of fragments of the facing strips and l rame.

Reference numeral 1 indicates a body or frame having at its upper and lower edges,

flanges 2 and 3, which 'project outwardly from said body on opposite sides from one another. Flange 2 has formed integral therewith a support 4 whose vfree end portion'is turned down, as at 5, and provided with a lug (j, disposed opposite a similar lug 7, formed integral with body or frame 1.

` Reference numeral S indicates an opening formed in flange 'Z and the support L1, and beneath this opening a gage to be arranged, when it is desired to tile the taker-teeth,l said plate being formed with a slot 10., one wall of which is inclined outwardly to facilitate the positioning of the teeth as will be readily understood. Gage plate 9 is provided adjacent its ends with strips 13,

plate 9 is adapted f flange 3.

screu7 threaded openings in which screws 11 are engaged, said screws projecting through flange 2 as clearly shown. Reference numeral 12 indicates washers, which preferably vary in thickness and are adapted to be arranged en said screws 11 above and below flange 2 to hold said plate in its adjusted p0- sition.

On opposite sides of gage plate 9, I arrange facing strips, 13, of metal, adapted to have the cutting teeth of the saw bear thereagainst during the operation of filing the tops of the raker teeth, and said facing strip's are preferably curved to conform to the of the saw as clearly shown in Fig. l. The facing strips 13 are provided with integral threaded Shanks 15 oglera'ting through flange ,2, and threaded on t e outer ends of'these Shanks are nuts tapered shims or spacing strips 16 of proper thickness may be inserted between the same and the flange 2, after which the nuts 14 are tightened to secure the said parts in adjusted position..

In jointing the tops of the cutting teeth, a file 17 (indicated in dotted lines in Fig. 1) is supported on lugs 6 and 7, beneath flange 2 and adjiisting screws 18 are engaged with the end portions of said file and tightened to ,cause the file to 'assume a curved form which will conform to the curved plane in which the free ends of the cutting teeth of the saw lie, as is obvious. ribs which are engaged by the side face of the saw during this jointing operation.

Body or frame 1 is also provided with a rib 20. This however is formed on the outer face of the body er frame, and is suitably spaced above flange 3 so as to accommodate therebetween a file (not shown) when it is desired to joint the sides of the cutting teeth, said file being firmly held in position by a set screw 2l.

Flange 3 is provided on its upper face with facing strips, 23, having their contiguous end portions formed with semi-circular cut-outs to lit about a gage 22, consisting of a screw adjustably mounted in a threaded opening in Facing strips 23 are provided with threaded shanlrs 251, having nuts 25, and like facing strips 13 are adapted to be held in a slightly curved form, and suitable spacing strips 16 are inserted between these facing strips and the adjacent iiange, as-desired (see Fig. 3). Gage 22 is designed for gaginglthe 14. To adjust the facing 19 indicates horizontal et yteeth after they have been swaged, will readily be understood the facing form temporary supports for enent with the tips of the cutting teeth the gaging operation lof the said raker in conjunction with gage 22 l. provide :l means for securing the same against accidental displacement, after it has been e properly adjusted. This means (see j consists of a slidahle member 25,

ed in an opening, formed in flange 8 am nommunicating .with the screw threaded ing in which gage 22 is mounted, and having its inner end formed Withrsections of screw threads and engaged with the screw threads of 22. A- screW 26 engages this slidable .lock member for sliding the same, and as 'willbe observed, when screw 26 is A adjusted sufliciently inwardly, the locking member, by friction, will prevent turningof 'the gage.

While l have herein shown and described construction which will carry out the various objects assigned thereto, I reserve the right to make such alterations and changes in the details of construction as fall 'within the scope of the appended claims.

Having thus fully described my inventionv What I claim as new and desire to secure by Letters P atent"of the United States, is:

l. A saw tool comprising a frame formed With a substantially right angular flange, gage means attached to said flange, flexible facing strips secured to said flange and cach being adjustable at both of its ends, and tapering shims between said facing strips and flange..

2. A saw tool comprising a frame. formed with a flange, adjustable gage means attached to said flange, flexible facing strips for said flange each being provided at both of its ends with shanks passing through said flange, removable tapering shims between said facing stri s and flange, and securing means for said s anks. l

3. A saw tool comprising a frame formed with a flange, a gage device passing through said flange, facing strips adjustablysecured to said flange and provided in their adjacent ends with ysemi-circular cut-outs to receive said gage device.
