Application filed February 5, 1827. Serial No. 16%;204,

This invention relates to scraping tools, and particularly, tools that are used for scraping flat surfaces formed ofwood.

The main object of the invention is to'provide a tool thatis particularly adapted for use in scraping wood floors, due tothe fact that the scraping blade can be readily detached from or combined with the blade hold the blade can beeasily adjusted at an angle to the blade holder when the tool is being used for scraping a surface adjacent a wall,

so as to cause the portions of the a holder that are engaged by the users hands to be spaced far enough away from the wall to eliminate the'possibility of the users hands striking against the wall. a t b Figure 1 of the drawings is a top plan view of a wood scraping tool constructed in accordance with my invention, illustrating in broken lines how the blade of the tool can be adjusted when the tool is bein used for scraping a surface adjacent a wal.

Figure 2 is a side elevational view of the tool, partly broken away, and Figure 3 is a top lan view, illustrating the device beingused for scraping a hori zontal surface adjacent a wall. Briefly described, my improved tool consists of a scraping blade A, formed preferably from a flat iece of steel, and a holder for said blade t at comprises a handle B and a blade receiving portion C at one end of said handle that is bifurcated or slotted transversely at its terminal end so as to permit the inner end of the blade to be slip ed into same. The slot 1 in the portion minal end of said O t at receives the blade extends transversely across the entire width of the terortion and inwardly a suflicient distance rom said terminal end to provide bearing surfaces for the blade that are of suflicient area to insure the blade being properly supported and maintained in operative. positionwithout the aid of a fastoning device or retaining device. The slot 1 can either correspond in width throughout its entire length to the thicknessof the blade, or the extreme inner end portionrof said slot can be made a trifle narrower than the thickness of the blade,-so asito 1 form a r shoulder 2 in said slot that servesasa stop or abutment for the inner endof theblade. \Vhileit: is not necessarytto use aufastening device to retain the bladein operativeposition in'the slotted portion C of'theholder, said portion can be provided with aset screw or similar devioe 3, ifdesired, for clamping the blade Ain the blade holder, as shown in brokenlines in Figurefl.

When the tool is intended primarily for use in scraping wood floors or other SUP-i V faces, which necessitate the user exerting coiisiderable pressure on the scraping blade during the scraping operation, it is preferable to arrange theterminal end of=the slotil in the blade receiving portion C at an angle to the handle B as Shown in Figure 2, so that when the tool isin use, with the bandle Bgrasped in the left hand ofcthe user, and the scraping edge of the blade, A in contact with the surface being scraped,-the user can exert considerable downward pressure on the blade and hold it flexed slightly or under tension by simply pressing: downwardly on the blade receiving portion C of the holder with his right hand. The particular angle at which the slot 1 .is disposed with relation to the handle B is immaterial and while I prefer to dispose the blade of the tool at an angle to the handle, so as to increase the leverage on the blade during a the scraping operation,the blade A can be mounted in the blade receiving portion C of the holder in such a way that it extends parallel to the lon itudinal axis of the handle. Due to the ing portion C of the holder is intended to be engaged by one hand of the user, in the operation of scra ing a surface with the tool, it is prefera le to provide said portion C with a hand grip D of any preferred shape and dimensions, which is herein illustrated as consistin of a curved surfaceat the top side of the blade receivin portion C act that theiblade receivof the holder which is convexed oth longitudinall and transversely so as to enable it to be gripped tightly by the users hand.

In order to prevent the blade of the tool from flexing too much, when the tool is in use, the blade receiving portion C of the holder is provided at its front end with a part 4 that projects forwardly from the outer end of the slot 1 in the portion C, and which overhangs the top side of the blade, the surface of said forwardly-projecting part f that is arranged in opposedrelation to the top side of the blade being inclined upwardly from the blade, as shown in Figure 2, so as to permit the blade to flex slightly and then come in contact with said part 4. Accordingly, when the tool is in use, the f0rwardly-projecting part 4; of the blade receiving portion C of the holder that overhangs the blade will act as an abutment or stop that limits the flexing of the blade in one direction, the abutment surface of said part being inclined relatively to the blade so as topermit the blade to flex a limited degree. In the normal operation of the tool the blade A will be arranged in longitudinal alignment with the handle B, as shown in full lines in Figure l, but when the tool is used for scraping a surface in close proximity to a wall, it is preferable to turn theblade A slightly relatively to the blade receiving portion C, as shown in broken lines in Figure 1, so that the handle B and the hand grip D, which are engaged by the users hands, will be spaced far enough away from the wall to eliminate the possibility of the users hands striking against the wall.

The blade holderv of the tool can be formed from anysuitable material, but I have found that a blade holder constructed of hard wood dle B and the blade receiving portion C'of the blade holder are immaterial, but I have found that when the holder is provided with a handle of approximately ten inches in length and provided with a blade receiving portion of approximately two inches in width, equipped with a slot 1 of approximately two inches in depth, that the tool is exceptionally eflicient for scraping hard wood floors, due to the fact that the user can easily exert the required pressure on the scraping edge of the blade and the blade of the tool can be easily removed from or inserted in the blade holder when it becomes necessary to re-sharpen the blade or replace a worn blade with a sharp one.

Having thus described my invention, what I clainras new and desire to secure by Letters Patent is:

A scraping tool, consisting of a relatively long handle that is adapted to be grasped by one hand of the user, a blade-receiving portion at one end of said handle, formed integral with the same and having a convexed top surface that is adapted to be engaged by the users other hand, a slot in said blade-receiving portion disposed at an angle to said handle and extending inwardly from the terminal end of said portion, said slot extending transversely across the entire width of said blade-receiving portion, a laterally-adjustable blade in said slot projecting forwardly and downwardly beyond the terminal end of said blade-receiving portion, and a projection on the terminal end of said blade-receiving portion that overhaiigs the blade and which is provided withan abutment surface for the blade that is disposed at an angle to the slot in which the blade is positioned.
