Application filed June 29, 1912. Serial No. 706,739.'

To auw/omit may concern.' 4 'Y Be itknoW-n that I, FREDERICK E. CoWnLL,

a citizen of the Unitedv States, residing at Copper Gity, Province of British Columbia, Canada, have invented certain .new and use# ful Improveinents in Saw-Sets, oftvhich the following-:is a specification.

This invention.o relates to hand operated s awsets, )and has orits object the provision of a tool of simple construction which may be operated Without fatig e to ettiand dnrabiiityoirthe san'e iiiay be inzo drin the accom- W'ill be hereinafter fully describedl the ncveljfeatures being subseqnentlipointed out iifthv'eclaims following they descptio l In' 'tle drawinesi-gine/las a sectional elevation of a saw et ,embodying my inventienqFig. 2 is a sectional view on the; line.

2 il/Fig. 15; Fig. 3 is' a detailfront elevathe anvil; 4 is adetail perspec- .t'iv .'vievv of the anvil adjusting device.

Iii' carrying out "my invention, l employ a body 1 which may be cast in one integral i l.pice and consists of a substantially cylindrieal mainl portion having .ahandle 2 eX- tending'downwardly from its rear end and is-.provided at its front end with a depending/saw supporting and/bracing headA 3. A'

lug or bracket 4 depends from thernain portion of the body 1, and a set' screw 5 is mounted in the saidv lug or bracket to bearI 4against the saw blade,indicated at 6, and ,clamf'the [same firmly against the' head 3 so asito support the same in proper posibetvveen the die and the anvil.

' 'Within the main portion of the body 1 is a longitudinal chamber. 7 openingiat its front end'above and in' advance of the lug or bracket i Iand opening 'at its rear end through .the vunder side of the body. Within said chamber 7 are transverse Webs or partitions .8 which form supports for the die or hammer 9, said die, hammer, or setting pin being normally held retracted W1thin the chamber by a spring 10 coiled around the pin bearing against the rfront web ciently set the teeth of a saw at ,any desired vor partition 8 and against a sto-p11 in the pin, as clearly shown. The sropll is con'- Patented Mai'. 1 1, H513.

vcniently a small pin inserted'thrmigh. the

setting pin or die, and to provide a. 'Wider support for the end of the spring, a Washer- 1:2 may be fitted aroundthe-die against' the said sto-p. rEhe frontend of tie' die' orv setting pin is beveled to 'engagethe saw teeth',`

land the rear end thereof beveled to bear agalnst the upper1 end-of an' operating lever 13 fulcrnmed. atv let 'withinthe chamber7 at the lower rear end thereof. The upper end of the llever 13 is provided With i cooperative relation to the die.. The bolt or Screivlf? is provided .with athumb nut so f angles, so that, by properly adjust-ing the anvil, a iace vcorresponding-to vthe angle'tobe. given the saw tooth maybe brought in.

20 on its outer -endA which may be turned home against the head 53 to thereby clamp the. anvil in'its adjusted position. The anvil" 'maybe raised or lowered so as to give the saw a coarser or finer .Set .by'n'ieau's of .the

regulating device 21 consisting of a disk or J plate 22 having,` a' centralfopening to t 'around the screw -17`betWeen the head 8 andthe anvil and a supporting' lip-or Wing'QS connected with the edgeof said disk or plate and adapted to project over vthe upperedge of the head 3.. The' edge of the-head is pro vided, immediately adjacentits center, with the oppositelyAr extending bevel surfaces '24,'

25', which extend in opposite directionsfrom the central vertical line of the head andare disposed at different angles. lVhen'thezlip I 23 rests in the angle formed by the surfaces 24, 525, the'screw' or bolt. 17 will .be :1t-the.

lower end ofthe slot 16, andthe anvil Will consequently be in its' lovvest'position so that face 24,'the screvv or bolt 17 lWillbe'brought to the center of the slot 16, While, if the'lip be caused to ride up the surface 25to the vthe coarsest set Will be given the saw. lf tlie lip be turned so as lto ridelup the snr-v upper end thereof the screuT or bolt 17 will be raised to the upper end ot the slot 16.

In this simple manner, I provide for adjustingl the anvil so as to permit the saw' being given a coarse or line set, as may be desired. The operation of the device is thought to be clear from the foregoing descriptionf" The tool is engaged over the edge of the saw, as indicated in Fig. l, and the thumb screu7 5 is turned home against the saw blade so as to hold 'it iirmly against the head 3.

,The anvil7 having been previously adjusted hile'the tooth is being set, it should befsoadjusted so 'to permit the saw being slipped through the tool so as to bring another tooth into position to be set Without requiring,1 manipulation of the screw each time a tooth is set. The adjustment ot the anvil is very quickly accomplished, and when the anvil has been adjusted, it will be securely held so that it will not be dislodged during the operation of the tool. The rotation of the anvil brings any desired :tace thereof in operative relation to the setting pin so that thetooth ma be set at any angle While the vertical adjustment of ,the anvil permits the device to ac `commodate saw teeth of any depth.

What claim is l. A saw set comprising a body. having a saw supporting and bracing head depending from its front end` and p-rovided'with a vertical slots` an anvihla member projecting from the said anvil through the said slot, and an anvil support engaging said member and resting upon the head and adapted to adjust the anvil vertically.

Q. In a saw set, the combination of a body havingI a head at its front end provided with a vertical slot, an anvil disposed adjacent the said head7 a pivot for said anvil extending through said slot and adapted to rotatably adjust the anvil, means for se* curing said pivot in the position to Which it may be rotated, and an anvil support engaging said pivot and resting upon the head.

A saw set comprising a body, a head at its front end provided With a vertical slot, an anvil, a pivot for the anvil projecting through said slot, and a support tor the anvil engaging. said pivot and provided With a lip overhangingthe head, the head bei-.ng

provided withl diverging beveled surfaces ot' different .degrees ot' inclination to be engaged by said lip.

In testimony whereof I aix my signature in presence of two Witnesses.
