FATE FFICE.

GEORGE McCONNELL, or ABERDEEN, WASHINGTON.

WOODWORKING-TOOL.

Application filed May 31, 1918.

To all whom it may concern: I

Be it known that I, GEORGE MoCoNNELL, a citizen of the United States of America, residing at Aberdeen, in the county of Grays Harbor and State of Washington, have intwo or more parallel grooves have been cut' by such tool.

One of the objects of the present invention is to provide a simple and practical tool designed to remove the wood from between two parallel grooves and smooth the bottom of the groove in a continuous operation. A further object is to provide a tool of the above general character which may be conveniently operated by a pneumatic tool retainer with great speed and accuracy. A further object is to provide a tool which will easily cut through knots or cross grain and with which it is unnecessary to provide a starting place for the tool by previous boring or cutting operation other than the use of the tool described in my above referred to co-pending application.

Other objects will be in part obvious from the annexed drawings and in part indicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the features of construction, combination of parts and in the unique relations of the members and in the relative proportioning and disposition thereof; all as more completely outlined herein.

To enable others skilled in the art so fully to comprehend the underlying features thereof that they may embody the same by the numerous modifications in structure and relation contemplated by this invention, drawings depicting a preferred form have been annexed a apart of this disclosure, and in such drawings, like characters of ref- Specification of Letters Patent.

Serial No. 237,440.

erence denote corresponding parts throughout all the views, of which Fligure 1 is a ide elevation of the complete too Fig. 2 is a plan view thereof; and

Fig. 3 is an end view looking toward the left in Fig. 1.

Referring now to the drawings in detail, 5 denotes the body portion of the tool, preferably made of forged steel, having a hexagonal or other vertical cross section whereby it may be more conveniently held and operated. The rear or right hand portion of this tool is provided with a reduced part 6 and a collar 7 adapted to be received by a pneumatic tool retaining device. The forward or left hand part of the tool is bent relatively upwardly at 8 at an angle of approximately 15 and is flattened out at each side of the center, as shown more clearly in Fig. 2 to provide a relatively wide cutting surface 10. Thi incline with respect to the source of power applied in operating the tool prevents it from cutting too deeply into the wood and permits it to be more easily controlled. The sides of the tool are bent upwardly at 11 to form guides coacting with previously formed grooves and they are also provided with cutting surfaces 12. These cutting edges are so positioned and arranged that they may be easily ground or sharpened as may be necessary. It will thus be seen that the present tool is particularly adapted for cutting out the loosened chips between two or more parallel grooves made by the tool shown in my copending application. It not only smooths the bottom of the groove, but also the sides as well. Being operated by a pneumatic hammer, the tool will be driven rapidly and continuously in one direction and tests have shown that a 4" rabbet can easily be made across the grain of the wood at the rate of about a foot a minute. The width of the tool may be varied as desired.

The present invention is of simple and practical construction and is believed to accomplish, among others, all of the objects and advantages herein set forth.

Without further analysis, the foregoing will so fully reveal the gist of this invention that others can by applying current knowledge readily adapt it for various applications without omitting certain features that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this inven tion, and therefore such adaptations'should and are intended to be comprehended within the meaning and range of equivalency of the following claims.

I claim:

1. An integrally formed tool for pneumatic tool retainers of the character described comprising a body portion having a forwardly and upwardly relatively inclined part with respect to the source of power provided with a cutting edge, and cutting edges at each end of said first mentioned cutting edge at substantially right angles thereto.

2. An integrally formed wood working tool of the character described comprising a body portion having a forwardly and upwardly relatively inclined part with respect to the source of power provided with a cutting edge, cutting edgesat each end of said first mentioned cutting edge at substantially right angles thereto, and means including Copies of this patent may be obtained. for

a shank and a collar whereby said tool may be operated in a pneumatic tool retainer.

3. An integrally formed wood Working tool of the character described comprising a body member having a relatively Wide forward portion inclined at an angle of approximately 15 with respect to the axi of the body member, a cutting edge along one side of said flattened portion, and guides at each end of said cutting edge.

4. An integrally formed wood Working tool of the character described comprising a body member having a relatively Wide forward portion inclined at. an angle of approximately 15 with respect to the axis of the body member, a cuttingedge along one side of said flattened portion, guides at each end of saidcutting edge, and a shank andretaining ring at the opposite end of said body portion adapted to be received in pneumatic tool retainer. e

In testimony whereof I affix my ignature in the presence of two Witnesses.

GEORGE MOCONNELL.
