SCRAPING-TOOL.

Specification of Letters Patent;

Application filed August 30, 1909.

Patented Oct. 11, 1910.

Serial No. 515,236.

T 0 all whom it may concern:

Be it known that I, VVILLIAM PENNELL, a citizen of the United States, residing at Berrien Springs, in the county of Berrien, State of Michigan, have invented certain new and useful Improvements in Scraping Tools; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in tools and more particularly to the kind known as scrapers.

One object of the invention is the provision of a tool constructed to remove hardened putty from a window sash.

Another object is the provision of a tool which may be employed for scraping painted surfaces and leveling roughened parts on a surface to be painted.

With these and other objects in view as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claim; it being understood that various changes in the form, proportion, size and minor details of the device may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming part of the specification :Figure 1 is a perspective view of the device. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a front end elevation thereof.

Similar numerals of reference are employed to designate corresponding parts throughout.

The handle of the device is designated in general by the numeral 5 and is preferably of metal. The handle may be of any desired length and has a compound curvature. One end portion of the handle is provided with a transverse recess 6, the walls of which are Fsprung apart as shown at 7 and 8, whereby as shown in the drawings may be suitably secured thereto by means of a bolt or rivet 10. The latter construction is preferable for the reason that the handle may be of malleable iron while the cutting head 9 may be of steel. As shown in the drawings that end of the handle remote from the hand-hold is, on the convexed surface of its curvature provided with an under-cut or rabbet 11, while its opposite or concaved face is, adjacent its extremity, beveled to the extremity as shown at 12.

The cutting head comprises a base portion 13 one end of which is seated in the undercut or rabbet 11 so that the outer face of the base portion will be coincident with the convexed portion of the handle. The base portion 13 extends considerably in advance of the extremity of the handle 5 and is oblong in contour and at that end remote from the end seated in the rabbet or under-cut 11, is sharpened to a cutting edge as shown at 14.

Rising from the opposite longitudinal sides of the base portion 13 are a pair of side walls 15 and 16, the forward edges of which are in a plane with and perpendicular to the cutting edge let of the base portion. These forward edges are sharpened similarly to the cutting edge 14 of the base portion 13. The rear edges of the side walls 15 and 16 are disposed in advance of and bear on the outer extremity of the rabbet or under-cut portion 11 of the handle. The upper corners of the side walls 15 and 16 are removed and the juncture of the said upper and rear side walls is rounded as shown at 17. The rear edges of the side walls in addition to being rounded are thickened so that a comfortable bearing surface is provided against which the operators thumb may be brought to bear in applying pressure to the tool when necessary.

With this construction it is obvious that I have provided a tool which will readily remove hardened putty from a window sash since it can be readily seen when the base portion 13 of the head is placed adjacent the window pane that by virtue of one of the side walls and cutting edge of the base portion, a right-angular cutter will be formed which will correspond to the angle formed by the putty on the glass and sash, thus making it possible for the tool to be readily passed between the putty, sash and pane.

It will be observed when the tool is employed for removing putty as just described that owing to the curvature of the handle the hand of the operator will not contact with any portion of the glass or window sash, thus reducing the danger of cuts by the glass should the latter from which the putty v is to be disengaged, be broken.

It will be further observed with a device of this kind thatthe operation of scraping the paint from surfaces and removing obstructions and roughened places from surfaces may be readily accomplished by using the cutting edge 14 of the base portion.

It will be further observed that the device is exceedingly simple in structure and comparatively inexpensive to manufacture, embodying few parts and these so arranged that the danger of derangement will be reduced to a minimum.

What is claimed as new, is

A tool consisting of a shank having a pair of spaced approximately parallel ears projecting laterally from one end, said shank and ears having their forward ends sharpened, the rear ends of said ears being round and provided with a bearing surface against which the operators thumb may be placed in applying pressure to the tool.

In testimony whereof, I afiix my signature, in presence of two witnesses.

' VILLIAM PENNELL.
