GRASS-HOOIQ Application filed. April 17, 1916.

T 0 all whom it may concern:

Be it known that I, HonA'rio S. EARLE, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Grassliooks, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to grass-hooks, and its object is a grass-hook of simple and durable construction in whic i the blade may be readily adjusted and set at various angles with the handle. Another object of the invention is a grass-hook in which the blade and handle are secured. together in a detachable relation. Another object of the invention is a grasshook having a blade of peculiar form pivotally connected wit-h the handle and provided with a tang of such form as to enable the blade to be secured at various angles with the handle. An additional object of the invention is a blade provided with a tang as stated and means for securing a blade to the handle adapted to wedge the blade in place and providing a strong and durable construction for that purpose. These several objects and novel features of the invention are hereinafter more fully described and claimed, and shown in the accompanying drawing in which Figure 1, is a plan view of a grasshook embodying my invention.

Fig. 2, is a section taken on line :Z/f(/ of Fig. 1.

Fig. 3, is a. cross-section of the blade taken on line of Fig. 1.

Similar characters refer to similar parts throughout the drawing and specification. The blade 1 may be formed of any suitable material, but is preferably made of sheet metal, tapering in form, as shown in Fig. 1, from the point to the heel and having upstanding flange 2 on the rear edge. The forward edge of the blade is sharpened as indicated at 3, and the blade is ribbed as indicated at 4 in the drawing, to provide a blade of proper strength although of comparatively thin material.

The blade is provided with an integrally formed. tang 5 at the heel and. the e i Specification of Letters Patent.

of the tang is notched as indicated at 6. The handle is preferably of metal shaped substantially as shown in the drawing and provided with a flattened terminal portion 7 engaging one surface of the tang as shown. The portion 7 is apertured at 10 to receive a substantially U shaped fastening or bolt 8 which is provided with a head 9 on one leg preventing the bolt from passing through the aperture. The opposite leg 11 of the bolt is threaded to receive a nut 12 and the leg 11 is formed at an angle with the body portion of the bolt greater than a right angle. The aperture 10 is of greater diameter On one side as shown at tapering toward the seat for the head 9. Also the aperture in the portion 7 of the handle through which the leg 11 passes is greater in diameter than the bolt to allow the same to move freely by tightening 0r loosening the nut 12. By this arrangement on loosening the nut 12 the bolt may be forced downward through the handle without binding in the apertures therein.

The end of the terminal portion 7 of the handle has the upper surface formed at a slight angle providing a seat for the nut 12, as is required by reason of the angularity of the portion 11 of the bolt. The blade 1 is apertured at the heel to receive the leg 11 of the fastening device or bolt, and the blade pivots on this portion as may be understood from the drawing. The notches 6 are formed on an arc whose center is the pivotal center of the blade, and any of the notches 6 are adapted to engage against the headed leg of the bolt, as may be understood from Fig. 9, to prevent the movement of the blade on its pivotal point.

In securing the tang of the blade to the handleend '3' it will be noted that, by reason of the angular relation of the leg 11 to the body of the bolt 8, as the blade is forced downward on said leg 11 the distance between the point of contact of the blade with portion 11 and the headed portion 9 decreases. Therefore, the notched end 6 is forced snugly into engagement with the headed portion of the bolt. By screwing the nut 12 tightly in place, the blade is thus held practically ii'ninovable relative to the handle, but by loosening the nut 12 and at least partially withdrawing the blade from the portion 11, a sufiicient loosening of parts secured to enable the blade to be turned on the pivot and any one of the several notches 6 to be set to engage the headed portion 9. The blade may thus be set at various angles as is shown by full or dotted lines in Fig. 1, and is thus adapted for use as a corn knife, grass cutter, beet topper, or other similar purpose.

As may be understood from the foregoing the device is comparatively simple, and inexpensive to manufacture, and is readily adjusted to set the blade at various required angles as described. The blade may also be readily detached from the handle or folded relative thereto about the pivot le 11 by loosening the nut 12 sutficiently to zIlow the notches 6 to be withdrawn from engagement with the headed portion 9 of the bolt. By either of the above methods, the device may be folded to small compass convenient for carrying in the pocket of the user.

Having thus briefly described my invention and its utility, what I claim and desire to secure by. Letters Patent of the United States is 1. In a grass hook, a blade provided with a tang formed integrally with and extending at an angle thereto, the terminal edge of said tang being arcuate in shape and notched, a handle, releasable means carried by the handle, pivotally supporting the blade and adapted to bind the blade and handle together in wedging relation by relative longitudinal movement of the handle and blade.

2. In a grass hook, a blade formed of sheet metal provided with an integral tang extending at an angle to the blade and terminating in an arcuate end and notched about the edge, a handle in pivotal relation to the tang, and means for securing the handle to the tang adapted to draw the handle longitudinally of the tang and hav ing a part adapted to engage any of the said notches.

3. In a grass-hook, a blade having a tang terminating in a notched end, said blade being apertured at the heel and said notched end being formed on an arc whose center is substantially the center of the aperture, an apertured handle adapted to be secured to the tang, and a U shaped bolt or fastening, one leg thereof being adapted to pass through said aperture, providing a pivot for the blade, the said notched end being adapted to engage the opposite leg of the fastening, and a nut for the bolt to secure the parts together.

a. In a grass-hook, a blade, a tang, formed integrally therewith terminating in an arcuate notched end, the blade having an aperture coinciding approximately with the center of the are and the handle having an apertured end adapted to be secured to said tang, a U shaped bolt having one leg engaging in said apertures, the notched end engaging the opposite leg of the U, and a nut for drawing the bolt to place to bind the blade and handle together.

5. In a grass hook, a blade having a tang formed at an angle therewith and terminating in an arcuate notched end, the blade being apertured substantially at the center of the are, an apertured handle, a U-shaped bolt or fastening having one leg in pivotal relation with the handle and the other of said legs being formed at an angle greater than a right angle with the body and adapted to pass through the said apertures in the blade and handle, the said notched end being adapted to engage the first named leg of the bolt, and a nut for drawing the last named angular leg to position to wedge the notched end into engagement with the first named leg.

6. In a grass hook, a blade, a tang formed integrally therewith lying at an angle to the blade and terminating in an arcuate notched end, the blade having an aperture coinciding approximately with the center of the arcuate end, a handle having an apertured end adapted to be secured to the tang, a U-shaped bolt having one leg pivotally mounted on the handle and adapted to swing in the plane occupied by the longitudinal axis of the said leg, the opposite leg of the U bei formed at an angle to the body of the bolt greater than a right angle and adapted to pass through the apertures in the blade and handle, the aperture in the handle having a diameter slightly greater than the diameter of the leg to allow the same to pass freely threthrough, and a nut for drawing the angular leg to place and by reason of the angularity of said leg forcing the notched end of the tang into engagement with the opposite leg of the U.

In testimony whereof, I sign this specification.
