Y To all who'm'z't mag/concern Be it: known th at I, Ronnnr big-RHODES; a-citizen of the:United-Staten-nestling at V Greensburg, in the county of Westmorelani.
-State of Pennsylvania, have invented a new and usefullmprovement in Noodworking 4 Tools, of which thefollowing is a full, clear,
a and exact description. y
The present invention-relates broadly to wood-Working tools and more-particularly to tools of the-type ordinarilyreferred to as scrapers" and adapted for use in finishing d-isadvantages, in JFthat each adjustment,

enlarged scale on the line" Ill- IV. offlFig- In the illustrated embodiment or. the invention' there is provided clamping means a for the scraping s blade 2 comprising "a supporting member 3 and-a backing member 4. Both the supporting member and theflbackzing member have t-heir cooperating. faces curved, one to present a concave surfacevand the other aconvex surface, Wherebyi-the clamping operation Will be reflective for curvingsthe scraping. blade.
;The supporting member 3 may be carried by arms5 projecting downwardly from enlargedbearing portions 6 having openings formed therein to receive a transversely 6X,
the bearing portions 6 are .arms Slying in parallel spaced relation, as clearly'shovvn in Fiqure 2 and provided :Wlilll enlarged bearing; portions 9- at their outer ends.
1 The. backing. member 1 may be formed to comprise spaced .para'llelly extending side members 10 adapted to embrace therarms 8, the backing member itself extending transversely I with respect to .the jsidevinembers FrbGI-S at their forward portions are provided withabearing openings adapted to extfend in axial alignment" with the openingsfformed in the bearing-portions 6 and receive the ends of the pin 7. The side Walls attheir rear portions-preferably have solid portions adapted to; embrace the bearing portions 9 formed on-the ,arms 8. Byoreasonvof this construction the side membersyare effective fore-maintaining in operative position-a pin 11- extending through the: bearing-portions 1 in-the iarmsi8-and'ha'ving its ends abutting h againstrthe inner surfaces o f-the walls 10,.
For maintaining the clampingmembers in 2 they desired position and permitt1ng-- opera tionthereofithere may berp-rovided avhandle 12. a' l hisehandle is: preferably keyed to a handlegbar- 13Which:extendsglongitudinally 1 through a; spacing sleeve 1&7. and engages a1 transversely extending ethreadedopenmg 1n 1 thepin 7.- The end of the -sleeve ,14.adjacent 1;. Figure-8 is-sa detail;sectionalevievvs on theline III-JILotEi-gure 2r h&.-h&ndle;;.being the clamping membersmay be proyided-with raecurved @c'lamping fac'e 41- 5, adapted to entending pin 7 Extending rearwardly. from as will be clearly apparent, The sideamem- 2 i ,aavgoee gage the front bearing portions formed on the supporting and backing members. By reason of this construction, it will be apparent that upon rotation or" the handle 12 in one direction the sleeve ll will be moved to release the clamping members and permit angular adjustment thereof relatively to the handle bar, while movement of the handle in the opposite direction will be eiiecti as for clamping the parts in their adjusted position.
For moving the supporting member 3 relatively to the backing member 1 to clamp the blade in position, there is provided a second handle 16 operatively secured in any desired manner to the tem 1'? which is provided with a threaded lower portion 18 adapted to engage an interiorly threaded transversely extending opening formed in the pin 11.
Loosely surrounding the stem 17 is a clamping plate 19 formed with a flat upper surface adapted to permit rotational engagement with the handle 16 and with a curved lower surface adapted to engage the side walls 10. These side wallsat their rear portions are preferably curved in such manner as to provide arcuate bearing surfaces whereby when the handle 16 is turned in one direction to release the clamping member 19 the handle may be swung bodily, together with the pin 11 to change the effective posi tion of the handle with respect to the clamp ing members. In this manner the effective downward pressure which may be exerted by the handle 16 may be easily varied.
In addition to providing an adjustable mounting for the handle 16. the threaded stem 1? is also effective for clamping or releasing the blade. It will be apparent. that during the clamping operation the stem 1'? is threaded into the pin 11 and thereby swings the supporting member about the pin 7 as an axis. lVhen the blade is being released the reverse operation occurs.
For adjusting: the position of the blade with respectto the clamping members, I have provided adjusting bars 20 havinghooked lower ends 21 adapted. to extend through the openings 22 in the blade 2 and with threaded upper ends 23. These bars are vertically adjustable in sockets 24 formed in the backing member 4: outside of the wall 10, and having enlarged interiorly threaded recesses 25 at their upper portions. The supporting member 8 may be provided with slots 26 to cooperate with the lower hooked ends of the bars 20. Threaded upon the upper ends of the bars and also having a threaded engagement with the recesses 25 are nuts 27. These nuts preferably have threads of difierent characters cooperating respectively with the bars and with the recesses whereby the movement of the nuts will be eilective for imparting an am plified movement to the blade.
This may be accomplished. by providing a left-handed thread on the bars 23 and a right-handed thread in the recesses 25, or vice versa, as will be apparent.
The scraping operation may be facilitated by providing a foot 28 having a stem 29 adjustably engaging the socket 230 which is slidably mounted on the sleeve 1 1 and which may be clamped in adjusted position thereon by the set screw 31. In some instances it is desirable to move the foot 28 from the position shown in full lines in Figure 1 to the position illustrated in dotted lines there in for permitting the scraper to be operated in a manner similar to the operation of a plane. it will be apparent that by adjustin the position of the foot. the width of the throat provided between the same and the cutting edge of the blade may be accurately regulated.
it has been found desirable to mount the stem 29 nearer one end of the foot 28 than the other, as this permits the foot to spring upwardly a slight amount at its relatively tree end when sufficient pressure is applied the handle 16. This enables the operator to easily remove a greater amount of ma terial in small local areas. as may be desired.
The locking member 4- is preferably so shaped as to provide a small portion 32, as clearly shown in. Figure 4, extending at an angle or cuiwed'with respect to the lower portion of the back edge of the backing member. The scraper during operation may be easily rocked over a wide angle about this portion, thereby providing another means for determining and regulating the depth of cut. This operation is independent of the provision of the foot 28.
Vv'ith the present construction it will be obvious that the position otthe scraping blade is adjustable relatively to both of the clamping members and independently of the msition of the handle 12. This permits the blade to be advantageously adjusted while maintaining the outer parts in the desired an gular relationship.
Further advantages of the present invention arise from the provision of an angularly adjustable handle 16 permitting the effective leverage thereof with respect to the craping blade to be varied as desired.
