EXCAVATING-TOOL.

Specification of Letters Patent.

Patented June 30, 1908.

Application filed November 4, 1907. Serial No. 400,528.

To all whom it may concerh:

Be it known that 1,11-11L0 Score, a citizen of the United States, residing at Fine, in the county of St. Lawrence and. State of New York, have invented certain new and useful Improvements in Excavating-Tools, of which the following is a specification.

This invention relates to improvements. in

tools, designed for use in connection with earth excavation, grubbing or ditching, and

a the invention relates particularly to manually operated excavating tools, such as picks, mattocks and the like.

The object ofthe invention is to provide excavatingtfids which are simple 1n construction, d able and inexpensive, and whereby the work of di ging or excavating may be done more quick y and requiring less manual power for their effectual operation than the old style or make of tools of the class. I

The several features and parts of the invention will be readily understood from the detail description which follows, reference being had to the accom anying drawings forming a part of this specification, in which-- Figure 1 is a side elevation of a pick. Fig. 2 is a plan view of'the inner face of the same. Fig. 3 is a plan view of the back of a ick. Fig. 4 is a cross-section of one of the bla es or arms of a pick, taken, on the line a.a of Fig;

2 showing the triangular form of said blades. Fig. 5 is a plan view of a modified form of tool, showing one narrow, triangular and one broad. semicircular blade. Fig. 6 is a secgonal View, substantially on theline ac-m of 1g. 5. Similar reference numbers designate like parts throughout the several views.

In;thedrawings, 2 represents the metallic portion of my im roved tool, and 3 represents the narrow b ades which are preferably blades of t e tool than if they were formed I "square or fiat as formerly made, and furtherm e, it has been found that a blade formed as s own herein, is capable of being forced or driven into the earth to a greater depth and with the expenditure of less force or power, because of its peculiar shape, than any other form of such tool. \After a pick or other tool having'my triangular bladeis sunk into the the loosening of a large section of earth or clay to be removed. By this means a larger amount of excavating may be accomplished in the same or less time than by the use oi the old style of digging tools. 5 represents the central )ortion of the tools shown in Figs. 1, 2, 3 and 5 in which the handle 7 is iittcd, an oval-sha ed eye 8 being provided for the purpose. T e oint 6 of the blades 3 are preferabl beve cd, chisel-like, as shown in the drawings, so that they may cut their way into or through the earth more readily.

In Fig. 5 I have illustrated a modified form of excavating tool, in which the same general construction shown in the former figures is followed in all parts, except one blade 9, which is formed much broader than blades 3, and its outer end is made semicircular, the cutting edge or point thereof having a bevel 10, which gives it substantially the lorni of a half-round chisel or gouge. This blade 2) is for use in grubbing or in smoothing or leveling the bottoms of cellars, or trenches. In finishing trenches in which drain-pipe is to be laid the blade 9 is used for rounding the bottom so as to conform to the shape of the piping. In case of grubbing 1 find that the blade 9 will cut through roots of considerable size more readily than the old form of pickaxes or grub-hoes.

1t is obvious that the principles of my improvement may be applied to other forms of excavating tools than those described and shown herein, and still be within the scope defined by the appending claims.

Having thus described my invention what I claim as new and 'desire to secure by Letters Patent is- 1. A tool of the class described, comprising a metallic body having a central eye or opening to receive a hand 0, a pair of oppositely arranged blades having three substantially equal sides formed with said body, the said sides being dis osed in such manner that the outer face or ack of each blade is flat, the inner face of each blade having a sharp central ridge, and the outer ends or points of said blades being beveled to form a cutting edge, substantially as described.

2. A tool of the class described, com rising a metallic body having triangularly ormcd blades projecting in opposite directicns therefrom and disposed so that the .ol ter' face of each blade is flat and the innerfaceor side thereof is formedwith a sharp central rid e, the outer end of each blade being 1bei7-..

ele and an'oval-shaped eye in the center of said body. adapted to receive a handle, sub' 'stantially as described.

3. A tool of the class described, comprising ainetallic body in combination with an openating handle, -a pair of triangularly formed substantially as described.
