1 Claim. l

This invention relates to an agricultural. garden, etc., device.

The chief object of this invention is to provide a flexible or resilient bladed cutter of handled type whereby tall grass, weeds, shrubs, and small trees, etc., may be cut and hedges, bushes, and trees may be trimmed.

The chief feature of the present invention resides in applying in endwise relation to an elongated light-weight handle a curved, tempered spring steel strip sharpened at opposite sides and the free end, if desired, which strip is of very thin gauge so that in use little or no jar is transmitted to the hand or arm.

One feature of the invention resides in the use of the device for the cutting of tall grass or weeds in much the same manner as one putts with one hand in golf. The blade despite its curvature, cuts a relatively wide swath.

Another feature noted is that the round or blunt point can be used as a weed digger.

Still a further feature noted is that for bushes and heavy stalks, and very small trees, the invention is used as a driver is used in golf, all without appreciable shock.

Other objects and features of the invention will be set forth more fully hereinafter.

The full nature of the invention will be understood from the accompanying drawings and the following description and claim:

In the drawings Fig. 1 is a perspective view of one embodiment of the invention, the major portion of the handle being broken away.

Fig. 2 is an enlarged longitudinal sectional view of the blade and handle at the connection therebetween, the handle notch and blade thickness being approximately twice actual thickness and handle thickness being approximately to scale, the section being taken on line 2-2 of Fig. 1 and in the direction of the arrows.

Fig. 3 is' an enlarged transverse sectional view of the blade, same being taken on line 3-3 of Fig.

I l and in the direction of the arrows.

Fig. 4 is a plan view of the free end of the blade shown in Fig. l y

Fig. 5 is a similar view of a modified form of blade end.

In Figs. 1 to 4 of the drawings there is illustrated one embodiment of the invention. indicates an elongated Wood handle which at one end is notched or kerfed as at I I, same terminat- .ing as at I2.

Therein is seated the base or one end I3 of a strip of steel I4. 'I'his is of tempered spring character and includes apertures I5 in longitudinal alignment.

The notched end of the handle has similarly aligned and spaced holes I6. Seated therein are the carriage bolt type members having threaded shanks I1, the polygonal portions I8, the larger circular bearing portions I9 and the flat larger heads 20 with screw driver slots 2|.

When same are seated in holes I6 of the handle and apertures I5 of the 'blade and have washers 22 and nuts 23 applied thereto and tightened thereon, the portions 22 and I9 embed in the handle and blade is rigidly anchored thereto. The blade I4 projects longitudinally from the notched end of said handle I0.

The blade is curved as indicated at I4 so that the free end 25 may be positioned'approximately at right angles to base portions I3 thereof.

Each side edge of the blade I4 is sharpened as indicated at 2B in Fig. 3 and the tip 25 is also sharpened as indicated at 21 in Fig. 4.

In Fig. 5 the blade tip |25, sharpened as at |21, is shown semi-circular in outline instead of substantially rectangular asin Figs. 1 and 4, same having rounded corners 28.

The length and width of the blade is optional. Steel having 1.02% carbon and .70 manganese with a Rockwell test of (3481/2 has been found suitable. The strip is approximately .023 of an inch thick and approximately one and a half inches wide. A strip of this tempered spring steel about 14 inches long curved to an approximate radius of about ten inches and anchored by fig to 1A. bolts as illustrated has been found eminently satisfactory for all the purposes herein described including hedge, tree and shrubbery trimming as well as limb lopping.

The foregoing dimensions and specications are illustrative only. Such a blade can be readily curved or straightened as itis desired to depart from the transverse positioning recited.

In swath cutting the curved portion of the vblade strikes the ground, and flattens the former, but due to the follow through cuts the grass, weeds, etc., ahead of the point of impact and due to the impact cuts the swath specified. l

While the invention has been illustrated and described in great detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character.

The several modifications described herein as well as others which will readily suggest themselves to persons skilled in this art, all are considered to be within the broad scope of the inventiQn, reference being had to the appended claims.
