IMPROVEMENT lN SHOVEL-PLOWS.

Specication forming part of Letters Patent No. 96.010, dated October 19, 1869.

'o LZ-Z whom, it 77am/ concern:

Be it known that I, E. A. KAMERER, of Greentown, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Shovel-Blows; and I do hereby declare that the following is a full, clear, and exact description of my invention, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon, of which drawings- Figure l is a plan of' my improved plow. Fig. 2 is a side elevation, and Fig. 3 is a front elevation, of the same.

My invention consists in so constructing a shovel-plow with three shovels, one of which is fixed and the others movable, as thatthe movable shovels may be turned at any desired angle with the plow-beam, and set at any required distance from saidbeam, and, also, so that said movable shovels may be moved backward and forward with respect to the fixed shovel, so as to bring the three shovels nearly into line7 with each other, and thus cause t-hem, when brought closely together, to act in a manner similar to a single-shovel plow, which is often very desirable in cultivation between rows of plants.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the annexed drawings, A represents the plow -beam, to which are secured the fixed sh ovel-standard D and the handles B B, which are united at their upper ends by the cross-bar C, which is fixed in the standard D, as shown.

The side beams,FF,have the irons S S bolted to their front ends, as shown, and the bolt E, which is passed through one of the holes, d, in the plow-beam A, passes through holes in the ends of the irons S S, which are thus pivoted to the plow-beam, where theyr are held by the nut on the lower end of the bolt E, as shown.

The irons I I are bolted to the rear ends of' the beams F F, and have the arms H H pivoted to them by the pins K K, as shown. These arms H H are fixed in the side shovel-standards, G G, which have the shovels L L bolted to them, and said standards are braced against the strain thrown on them in cultivating by the braces W W, which are bolted to the beams F F, and have an eye at their lower ends, which are attached to the standards G G by the staples ff, as shown.

The regulating-arms M M are bolted, .by flanges at their ends, to the standards G G, and have the braces T T running down from them to said standards, as shown in Fig. 3. The holes b b are formed in these arms M M, which lie up under the plow-beam A, to which they are secured by a bolt, P, which passes through a hole, b, in each of these arms M, up through the longitudinal slot a in the plowbeam A, where it is secured by the thumbnut R.'

The shovel N is bolted to the fixed standard D, as shown, and the brace U is inserted between the plow-beam A and standard D, to strengthen said standard against the strain thrown on it in cultivating.

From the foregoing description of the construction of my shovel-plow it is readily seen that by loosening the thumb-nut R the bolt l? may be moved up or down the longitudinal slot a, which will cause a corresponding movement of the arms M M, and hence will turn the standards G G around the hinge-pins K K, (the staples f f allowing this change of position between the standards and braces WV W,) and thus will turn the shovels L L to any required angle with the beam A, where they can be secured by simply tightening the thumb-nut R. It is further evident that by changing the bolt P from one hole b to another the distance of the shovels L L from the plow-beam Avor from each other can be varied as desired. It is also readily seen that by loosening the thumb-nut R and taking out the bolt E the shovels L L may be moved back toward the shovel N, or, what is the same thing, the'plow-beam A,with its standard D, may be pushed forward, so as to bring the shovel N nearly into line with the shovels L L, and that they can be secured in this position by inserting the bolt E through a proper hole, el, in the plow-beam A. Aside from the advantages in cultivation resulting from the facility with which the three shovels can be brought into line with each other, this movement allows the operator to adjust the relative positions of the shovels so as to conform to the different lines of draft caused by the varying height of the team, and to better adapt the position of the handles, with respect to the shovels, to the requirements of the operator in manipulating the machine.

By removing the center shovel, N, a doublel shovel plow is attained without additional 2 eamo Y expense, and with but little more Weight than the ordinary double-shovel plow.

Having thus fully deseribed my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

1. A shovel-plow provided with one fixed and tivo movable shovels, when so constructed as that the movable shovels may be readily turned so as to assume any required angle with the plow-beam, and may be set at any desired distance from said beam, and also so that said movable shovels may be readily moved into or nearly into line With said iixed shovel, substantially as is herein set forth.

2. The arm M, rigidly attached to the shovel standard G, and held by a bolt, l?, Working in a slot, a, in the plow-beam A, when said arm serves both to hold the shovel-standard G at the required distance from the plow-beam A, and also to regulate the angular position of said standard with respect to said plow-beam," substantially as is herein speeied.

3. Pivoting the standards G of the side shovels, L, of a shovel-plow to the side beams, F, by means of a hinge-pivot joint, II I K, and brace WV, having a loose joint, f, with the standard G, substantially as is herein speoied.

As evidence that I claim the foregoing I have hereunto set my hand, in the presence of two Witnesses, this 14th day of July, 1869.

E. A. KAMERER.
