6 Claims. (Cl. 51-187) This invention relates to an improved attachment to be applied to a hand scraper of the type disclosed in Patent No. 2,494,455 dated January 10, 1950, and the principal object of the invention resides in the provision of a very simple and easily applied sandpaper holder, a part of which replaces the removable scraper blade of the patent and is held to the scraper by the means normally holding the blade, this blade-holding means also holding a strip of sandpaper to the attachment for sanding purposes.

A further object of the invention resides in the provision of a relatively simple and easily applied and removable attachment to convert a hand scraper to a sanding too], said attachment comprising a strip of substantially rigid, resilient material having a flange at each end thereof, one flange being insertable in the jaws of the scraper normally holding the removable blade and the other flange contacting the body of the scraper and being resiliently held thereto by the position of the device and the inherent resilience of th material of which the attachment is made, so that there is but a single fastener, i. e., the jaws of the scraper which hold the attachment to the scraper handle, the latter providing a handle for the sanding attachment; and the provision of a sanding attachment as above described which is made to be located at an angle with respect to the main bcdy of the scraper whereby the device is much more easily handled for sanding purposes.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a plan view of the scraper with attachment secured thereto;

Fig. 2 is a view in side elevation thereof;

Fig. 3 is an enlarged section on line 3-3 of Fig. 2;

Fig. 4 is an enlarged section on line 4-4 of Fig. 3;

Fig. 5 is a plan view illustrating the mode of securing the attachment; and

Fig. 6 is a perspective view of the attachment per se.

The main body of the scraper is indicated at 10 and this is a relatively wide member which is provided with a rearwardly extending handle 12.

The scraper is also provided with a convenient enlarged knob 14 to be grasped by the user during normal scraping operations well-known to those skilled in the art and which are more fully disclosed in the patent above referred to.

At the forward edge of the main portion 10 of the scraper, the same is provided with a fixed jaw 16, the same having a sloping lower edge 18 leading into a notch or cut-away portion 20.

There is provided a blade-holding plate generally in- 2,790,279 Pa't ented Apr. 30,1957

24 is provided with an aperture and receiving a stud or the like as at 26 .therethrough and through a corresponding aperture 28 in the body of the scraper, said stud extending upwardly.

The stud 26 is screw-threaded as at 30 (see Fig. 3) and engages a nut 32 fixed in the enlarged knob-like handle 14. 'The result of this construction is that the plate 22 is firmly and conveniently held by turning the knob 14, the nut 32 turning therewith, and thus the original blade, not here shown, is easily applied to and removed from the hand scraper.

The subject matter of the present invention involves as most clearly seen in Fig. 6 a very simple strip .of stiff resilient material generally indicated at 34. This strip of material is provided with a reversely bent inclined flange 36 at one end, this flange being relatively small; and a right-angled flange 38 at the opposite end thereof. Flange 38 is longer than flange 36 and itself terminates inan inwardly directed slanted terminal flange 40. If desired, a thin strip or sheet of soft material such as rubber or similar material 42 may be applied to .the under side of strip 34 between the flanges 36 and dicated at 22 and this has a somewhat distorted Z-shaped In order to apply the attachment to the scraper, it is merely necessary to remove the original blade by backing oif the knob 14 to loosen and remove the blade, and

then inserting the flange 36, the angle of which is provided to correspond with the angle of the clamping jaws identified as surface 18 and flange 25. Upon re-tightening the knob 14, the sanding attachment is securely held to the tool and to the handle, and the flange 40 is drawn up into tight engagement with the lower surface of the handle 12, see Fig. 2.

Of course a piece of sandpaper is intended to be used with this attachment and this sandpaper is indicated at 44. One end thereof is bent over to conform to flange 36 as at 46, and the other end is bent along the flange 38 and flange 40 as indicated at 48.

The two flanges 36 and 40 hold the sandpaper in the position shown and the operator then merely grasps handle 12 in one hand and knob 14 in the other hand in order to provide an extremely handy hand sanding tool. It is to be particularly noted that the angle of the tool handle as shown in Fig. 2 is very advantageous for ease in handling the device as the knuckles of both hands will be clearly remote from the surface being sanded and a stroke such as required for good sanding practice is easily obtainable by the use of the tool.

It is also to be noted that the attachment is held merely by a single fastener, it not being necessary to have any fastener for the flange 40; but if it is desired to have a positive securing means at this end of the device, the same could be provided by means of a stud 50 and for instance a Wing nut 52 to maintain the same in position as shown in dotted lines in Fig. 2. This is an alternative construction and does not limit the protection to be aflorded by the appended claims.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. A sanding attachment for a hand scraper having a handle and means to secure a removable blade to the scraper, said attachment comprising a member, a flange at one end of said member, said flange being adapted to be secured by said means, a second flange on the member to engage the scraper handle at a point removed from the said means and from ahe first flange, said second-named flange being longer than the first-named flange and spacing the member from the scraper handle at an incline with respect thereto, the scraper being gen- 2. A hand:sanding..tool. comprising a body,. a clamping jaw on the body, a separate stiff strip of material, a reversely inclined flange on the strip to be entered and removably held in the clampingjaw, and a second flan'ge" onthe strip spaced" from the first flangeto engage the one end being folded over the flange and held in: the jaw and the other end being held between said second flange and the tool. body in. spaced relation to the latter.

3. The tool. of claim 2- wherein the clamping jaw is the sole securing means for the separate strip, the latter being resilient and holding, the sandpaper at said other:
