ADJUSTABLE rLow {AND siiovnn Application filed February 28, 1927. Serial No. 171,636.

My invention relates to improvements in ad ustable plows and shovels, and it consists in the combinations, constructions, and arrangements hereindescribed and claimed.

An object of my invention is to-provide an adjustable plow and shovel which has novel means for holding the'shovel in ad'- justed position yet permitting the shovel to swing should it strike a stoiieor the like.

A further object of my invention is to provide a device of the type described in, which thenovel adjustment is positioned adjacent the shovel. I I

A further object-of my invention is 'to provide a device of the type described in which the shovel is so shaped that when a plurality of shovels is used upon a cultivator, they will overlap. v

A further object ofmy. invention 'is-to provide a-device of the type described which will sever weeds or vines of any type, and will not make furrows as does the ordinary shovel. I

A further object of my invention is to rovide a device of the typedescribed in which the shovel may be adjustably held in any desired position with respect to the surface of the ground.

I Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which 7 Figure 1 is a side elevation of the device as applied to a shank of a cultivator,

Figure 2 is a plan view of the device,

Figure 3 is asection along the line 33 of Figure 1, and

Figure 4 is a bottom plan view of a portion of the device.

In carrying out my invention, a supporting member will be a shank of a: cultivator, not shown. A body port-ion 2 is provided with an opening 3 which is adapted to receive the supporting member 1. Lugs 1 are integral with the body portion and are adapted to be drawn together by a bolt 5 for removably securing I provide the body portion to the supporting member- The body portion 2 is provided with an integral flange or lip portion .6 having an arcuate-shaped groove 7 in its inner surface. A clamp Shaving an arcuate-shaped groove 9 within one side thereof is provided 1 which in actual use the tongue 10 is receivable in the'groove 11 and thearcuate-shaped surface 17 is receivable in the arcuate-shaped groove 9.

The clamp 8: and the bracket 13 are adjust ably secured to the body portion 2=by means of a bolt 18 which extends through openings PATENT? witha tongue portion '10 whichis receivable within alongitudinally extending groovell' in the clamp 8, the head 15, and the flange 6. I From the foregoing descriptionof the va I have shown the device in the position in rious parts of the device,'the operation there I of may be readily understood. In Figure 1,

which it is best used. The dotted line A I represents the surface of the ground. As the device is moved forward in the direction of the arrow B, it is obvious that the shovel 12 for its entire width is disposedbeneath the ground and will sever all weeds or vines which happen to be in its path. during the forward movement thereof. If the shovel 12 should strike a stone or other obstacle which could not be moved by'the forward movement of the shovel, the friction between the arcuate-shaped surfaces 16 and 17 of the head or ball-shaped member 15 and the arcuat-e-shaped grooves 7 and 9 would be overcome, thus allowing the shovel to swing about the bolt 18 as a. pivot. The shovel and bracket may readily be reset, i. e., moved into their normal positions by making loose'the bolt 18. v

The purpose of Figure 4 is to illustrate how the edges and point of the shovel 12 are kept polished by constant use. This also illustrates that the shovel moves in a substantially horizontal plane with respect to the surface of the ground. During this movement the weeds lllu i or the like may be more readily severed. Furthermore the shovel may be moved with less energy and more'evenly in comparison with the ordinary type of shovel.

The adjustment adjacent the shovel makes it possible to move the shovel upwardly about the bolt 18 when the device is not in use. The

adjustment also obviates the need of pegs gated groove therein, means for ren'iovably se-.

curing said body portion to said support, a flange having an arcuate-shaped groove in tegral with said body portion, a clamp having an arcuate-shaped groove therein, a tongue portion integral with said clamp and receivable in the groove in said body portion, a bracket, a shovel rigidly secured to said bracket, a head portion integral with said bracket and having arcuate-shaped walls re ceivable in the arcuate-shaped grooves in said clamp and said flange, and means for adjustably securing said head portion between said clamp and said flange.

2. A device of the type described comprise ing a support, a body portion arranged to be secured to'said support and having an arcuate shaped groove therein, a shovel, a bracket see cur-ed to said shovel and having arcuateshaped Walls, one of which is adapted to be received in the arcuate-shaped groove of said body portion, a clamp having an arcuateshaped groove adapted to receive the other of said arcuate-shap'ed walls, and means for adjustably securing said bracket-between said body portion and said clamp JAMES T.
