IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 30,357, dated October 9, 1860; reissue No. 3,514-, dated June 22, 1869.

To all whom it may concern f Be it known that I, MATHEW G. SLEMMoNs, of Cadiz, in the county of Harrison and State of Ohio, have invented a new and Improved Double-Shovel Plow;v and I do hereby declare that the following' is a more full, clear, and exact description thereof, reference being had to the accompanying drawings making a part of this specification, in which- Figure l is a perspective view of the improved plow. Fig. 2 is a side elevation ot' the plow, and Fig. 3 is a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the several figures.

One object of this invention is to construct a double-shovel plow, whose shovels are secured to standards that are formed upon, and that form a part of, their respective beams, which latter converge toward their front en ds, and have a clevis so attached to these ends 'that the draft of the team will act equallyupon both plows, as -will be hereinafter explained; and another object is to brace handles, which are applied to converging plow-beams, in such manner that a rigid attachment ot' each handle is effected in a very simple and substantial manner. Another object is to unite the front endsof the plow-beams in such manner that the draft ring or clevis by which the plow is drawn will pull equally upon said ends, as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I will explain its construction and operation.

ln the accompanying drawings, A A represent the metal plow-beams, which are connected together so as to converge toward their front ends, at which points these beams are suitably connected, and provided with a clevis, B, which may be pivoted to a transverse pin, g, as shown in the drawings, or which may be applied in any other suitable manner, whereby a strong hitching attachment of the team can be made to the beams. By thus bringing the two beams A A together, it will be seen that the draft upon the clevis B will operate uniformly upon both ot' them in drawing the machine along. Each one of these beams A terminates at its rear end in a standard, A', which is formed by bending the metal, substantiall y in the manner shown in Figs. 1 and 2, so that each beam and its standard or depressed end A' will be formed ot' one piece of metal, or of the same piece of metal, thereby affording great strength, and admitting of the parts being made much stronger and with greater facility than if each beam and standard were made of separate pieces, and then secured together by bolts, rivets, or otherwise.

It is obvious that the curved form of the standards will be much stronger than an abrupt or angular shoulder, as the strain in the former instance is uniformly distributed, while in the latter instance the strain would be chiefly confined to the knee or angular shoulder. The invention is not, however, confined to the exact form of curve given to the standards shown in the drawings.

The shovels c o, which may be made of any suitable form, is preferably secured to the standards by shoulder-abutments d el, formed on the front edges of these standards by bolts the heads of which are countersunk into the shovels c c, and by recesses e e, which are formed in the top edges of the shovels, as shown in Fig. 1. The shoulders d d assist in preventing lateral as well as upward displacement of the shovels, and relieve the bolts ff from considerable strain. One of the beams A is somewhat shorter than. the other, so that one shovel, c, will be properly in advance ot' the other; and the two beams A A are connected together, near their rear terminuses, by

a transverse bar or tie-brace, D', which has its f ends reduced and passed through the beams, and also through the front ends of handles F F, and upon these ends nuts are screwed, so as to hold the parts together. This bar D not only braces the beams and standards against outward strain, but it also holds them against lateral compression.

If desirable, provision may be made for adjusting the bar D nearer to or farther from the clevis B, for the purpose of expanding or contracting the beams and their shovel-standards more or less, as may be required. The beams A A will spring at and near their front ends sufficiently to allow of said adjustments.

The plow-handles F F are attached to the beams A A at m m, and secured rigidly in place at any desired angle by means of rear supports and braces E E, which are attached to the beams, or to the upper portions ot' the standards A A', in rear of the handle-connections. The drawings represent each handle and its support and brace made of one piece ot' metal by splitting a bar of metal in the form of a fork, one prong of which forms a handle, and the other the support and brace; but I donot eonne myself to this mode of manufacturing the handles and their bracesupports. The tangs, which are formed on the upper terminuses of the handles, receive the wooden holders T T, as shown in thedrawings. The transverse bar D keeps the handles and their supporting-braces at the required distance apart. A

It' it is desirable to provide for adjusting and setting the handles F F at ditt'erent angles with respect to the plow-beams A A to suit different plowmen, this may be done by pivoting the front ends of the handles to the ends of bar D', and connecting the lower ends of the supporting-braces E E to the beams or standards by means ot' straps a, and bolts or screws e', which latter pass through oblong slots b made through said braces E E, substantially as shown in the drawings, Figs. 1 and 2. By loosening the screws e' the haudles can be adjusted, as above stated.

Having described my invention, what I claim as new, and desire to secure by Letters Fatent, is-- 1. Two converging beams, A A, each one ot' which has a shovel-standard, A', formed by bendingits rear end, substantially as described.

2. The converging beams A A, connected together, and constructed with curved shovelstandards A' A' upon'them, substantially as described.

3. The union of the front ends of plowbeams, which have their rear ends bent to form shovel-standards, by means of a clevis or device by which the team is hitched to the implement, substantially as described.

4. The converging plow-beamsAA, having shovel-standards A' A' formed on them, in combination with handles F F, and handle-supporting braces E E, substantially as described.

5. In combination with the foregoing, the manner, substantially as described, of adjusting the handles F F, and securing them to the beams at any desired angle.

6. Constructing .of one piece of metal a plow-beam, A, and a curved shovel-standard, A', with a shoulder, d., formed on the latter, substantially as described.
