I To all whom it may concern:

. ISAAC Mantra- 101" THRUVVA Eyoaauriivs INDIANA- C M NEDSAW I i T! ijApplication filed August 22,1913. Serial-No. 786,104.;

.isubject of the King of Great Britaimlr esid ing at Thru Valley, Yale county, and Province of British Columbia, Oana'da,have invented and discovered certain new anduseful Improvements in Combined Saw Sets, and Gages, of which the 'followingis a specification.

My invention relates to a combined saw set and gage and its objects are to provid'e a device of the type described that may be readily grasped and held in the handof the user during the setting and gaging operations and to enable such operations to be effected while the operative face, of the device occupiesthe same plane relative. to the face of the saw blade, thereby facilitate ing the operation, and enabling a simpler and more compact form of device to be employed. 'I 1 With these ends andothers in view my invention is embodiedlin preferable formin the device hereinafter described and illustrated in the accompanying drawings.

In the drawings Figureil is' a side" view in elevation, showing a sawin position to be set; Fig. 2, a similar view showing the saw in gaging positionand Fig. 3," a front" view in elevation. v i T Referring to the drawings, \1 is a solid block, preferably of substantially cubical form and of a size .an dgthickness to render it capable of being easily grasped in the hand of the saW fitter and'galso capable of offering substantial resistance to'the shock of the setting blow; Thisblock isprovided' 1 on the operating face: thereof with a flat sur-II face 2, adapted to .eXtend in avertical plane when the block is in the setting and gaging f positions. From -the ,upper edge of this face eXtendsto the upper edge of the block,

A v a beveled face 3, constituting an anvil surface and on which thesaw is adapted to be set at theproper angle. -1

An L-shaped' bracket ismounted on the upper horizontal face .of.theblock, :one arm 4 thereof being secured, preferablybya screw, to the block and the other arm 5 eX-' tending from the edge oftheganvil surface vertically upward in a plane parallel to'the plane of the flat face2. M

Mounted in the arm 5 near the upper end,

sistin'g of'a screw 6 having a knurled head 7. -fl-he end of the screw projects through" the'arm 5 and on the screw is mounted a =lock-nut 8 whereby, after the screw has been adjusted to the proper degree ofprojection, it may be locked rigidly in such position.

" In thefiat portion 2 of the block are H I mounted adjustable headless screws 9,;spa'ced' I- apart .sufiiciently to afford, a support for 5 thesaw blade and also constituting regulable set gage members.

The block is cut away at10 ,65 from the U lower edge of the block, this recessed part, '1 J01n1ng the fiat bearing surface 2. .Abracket e 11 ismounted in the lower face ofthe block 7 andfi's provided with an attaching arm 12,

and a gagingarm 13, the latter extendingg vertically from the lower edge of the block. I

This arm 13 is provided at its end with a laterally'projecting boss or prong llj form 1113; a fixed set-gage member.

In the use ofthe device, the block is. held v in the left. hand ofthe operator with the saw blade bearing against the fiat surface I Z'anda toothj projecting over the anvil .surface "Then the tooth isjstruck with a hammer tobend it over the anvil and give 1t thedesired set. Then by merely moving the block downward in the same plane until;

the'point of the tooth is brought opposite the screw 6, the prong and the gage screws 9l arecarried against the face of the blade leveling the blade and if the set is correct,

the point of the tooth will just touch the outer end of the screw 6, which has been set and locked to a predetermined degree of projection If .the'setis not correct the I tooth is bent backor down. Y

blade bears directly against the flat-surface I 2 of the block,the gaging screws 9' may be In order to enable the gagingjmembers I screwed outwardly-so as to'project beyond i the surface of the block to the desired degree, whereupon Twhen the sawblade'is placed against the'prong 14: and screws 9.

and leveled thereon, the tooth edge: of the blade will be pro ected outwardly from the I block to a greater degree;

The angle of set is determined the ex} tent of projection ofthe gage screw f I claim is: I

A combmed saw set and gage having a solid hand grip block; one face thereof forming "the bearing face forthe saw and having an anvil portion formed on said face, arms projecting in opposite direct-ionsfrom said block in line with said face, one of said arms having a bearing member for the sawblade and the other arm provided with an adjustable gage screw, in combination with headless adjustable set screws mounted in the solid block and-adapted to be moved in and out With respect to said bearing face, substantially as described.

In Witness whereofllhave'hereunto set my hand and seal-at Thru Valley, B. 0., this ninth'day of June, A. DJhineten hundred and-thirteen. I
