SPECIFICATION forming part of Letters Patent No. 620,849, dated March '7, 1899.

Application filed January 25, 1899. Serial No. 703,369. (No model.)

T all whom, it may concern:

Beitknown that I, CHARLES ALBERT LONG, a citizen of the United States, residing at Pomeroy, in the county of Garfield and State of WVashington, have invented a new and useful Hoe, of which the following is a specification.

This invention relates to hoes; and the object of the invention is to provide a simple and efficient device which in the preferred construction thereof consists of a blade, a handle, and a shank for attaching the handle to the blade, and these parts maybe made of any suitable material, and the point of attachment between the shank and the blade is upon the center of gravity of the latter, whereby the weight of the blade is evenly distributed at all places about said point of attachment when a point of the blade is in use or when any part of said blade between its points is in operation, and by reason of this peculiar feature when the cutting edge of the blade is utilized for severing or incising a root or stalk said cutting edge will be caused to evenly pass through the root or stalk and make a clean clear cut.

In the present case the blade is concavoconvex in cross-section, and the handleis secured to the blade upon the convex side thereof, so that when the blade is incontact with the earth the simple act of drawing the same forward will cause the cutting edge or point thereof to enter the ground or earth, the depth being regulated simply by upward or downward pressures, as the case may be, upon the draft or grasping end of the, handle. By reason also of this feature of construction the act of pulling the blade forward so disposes the cutting edge thereof at a proper inclination to the soil that the latter acts to sharpen or maintain said edge at the proper bevel, thereby keeping the same in proper condition for use as a cutting implement.

With these ends in view the invention consists in the novel combination of elements and in the construction and-arrangement offorming a part of this specification, and in which Figure 1 is a perspective view of a hoe constructed in accordance with m y invention. Fig. 2 is a cross-section thereof, taken on the line 2 2, Fig. 3, and illustrating the peculiar dishing of the blade. Fig. 3 is a sectional face View, the section being taken on the line 3 3 of Fig. 2. Fig. 4 is an enlarged detail showing the wed ge-shaped separatingdevice.

Like characters denote like and correspondingparts in each of the several figures of the drawings.

In the drawings the blade of the hoe is designated by A, and it is substantially angular in shape and is provided with a series of three acute points 2, 3, and 4, located at remote distances apart and separated by concave edges a, b, and c, by reason of which I am enabled to obtain very sharp points, which aid materially in sinking the blade into the ground when used in certain cases. The concaved edge 0 is bounded'by the

curved lines

5 and 6, which merge into the points 3 and 4t and touch at a place perpendicular to the point 2, as shown clearly in Fig. 1, and these three concave portions are beveled or sharpened to produce cutting edges for cutting weeds and the like.

The handle 7 of the hoe is usually made of wood and is secured in the'ordinary manner in the socket S of the shank 9, that part of the shank immediately adjacent to the blade being curved and having its heel 10 secured to the convexed or rounded surface of the blade, so that the center of the point of attachment of said heel and the center of gravity of the blade will agree, whereby the weight of the blade is equally distributed at all points about the shank-heel 10, so that when any portion of the blade is in use the portions not in use will serve to counterbalance the operating or working part.

I prefer to make the blade in concavo-convex shape, and uponan inspection of Fig. 2

of the drawings it will be observed that the handle 7, through the intermediate shank 9, is connected with the convex or bulged side of the blade, so that as the latter is drawn forward the draft exerted upon the blade transversely thereof will tend to sink the cutting edge into the ground, the depth being regulated simply by the pressure of the user upon the handle transversely thereof-that is to say, if the hoe tends to sink too deeply into the ground the pressure will be upward, and if it is necessary to lower the same the pressure upon the handle will be downward, and these efiects can be regulated with great nicety and ease by the user. When the point 2 is sunk into the ground and the cutting edge or concave surface a strikes an obstruction, such as a root, the lateral motion of the blade will be prevented by the soil or earth as said blade moves forward, the pressure being applied at right angles to the cutting edge I), so that said cutting edge a will be caused to cleanly pass through the root and the latter will be severed with a shearing cut.

The blade constructed has three points 2, 3, and 4, each of which is capable of use for certain purposes, and the concaved portions a b 0 between said points can be used for other purposes.

In connection with the shank 9 I provide a wedge-shaped separating device which is secured to and depends from the curved portion thereof and which is also fixed to the blades, these parts usually being made in one piece, and the sharpened or cutting edge of this device is adapted to come in contact with the soil as the hoe-blade is drawn forward, so that the soil is separated into two portions and the wedge-shaped device at its upper side is of substantially the same width as the curved portion of the shank, so as to deflect or guide the earth away from the shank, as when such earth is wet or damp it tends to clog or stick to the shank to such an extent as to interfere with the easy operation of the implement.

The concave portions (1, b, and c are shown as being relatively deep, thereby securing three very acute points, which assures their penetration into the earth with great facility, this action being augmented by the concavoconvexity of the blade, and the degree of entrance of the latter into the soil can be easily adjusted by raising or lowering the handle. Also a wide surface can be covered by the expenditure of a minimum amount of power.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what I claim is 1. An implement of the class specified consisting of a blade having a series of three acute points separated by concaved edges, and a shank connected with the blade, the place of attachment of the shank to the blade being upon the center of gravity of the latter, substantially as described.

2. An implement of the class specified, including a concavo-convex blade having a series of acute points separated respectively by concaved edges.

3. An implement of the class described consisting of a blade having a series of three acute points separated by concaved edges, and concavo-convex in cross-section, and a shank connected with the blade, the place of attachment on'the shank to the blade being upon the center of gravity of the latter, substantially as described.

4. An implement of the class specified, in-

cluding a concavo-convex blade having a series of acute points separated respectively by concaved edges, a shank connected with the blade, and a wedge-shaped separating device secured to the shank and also to the blade the width of said wedge-shaped device at its widest point being substantially the sameas that of the shank.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

CHARLES ALBERT LONG.
