IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 18,783, dated December 1, 1857.

To all whom it may concern:

Be it known that I, ROBT. B. WINSTON, of Richmond,Virginia, have invented certain new and useful Improvements in Flows; and I do hereby declare that the following is a full and exact description of the same. reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the peculiar set ofthe beam, and also in the arrangement forthe easy adjnstability of thehandles.

In order that others skilled in the arts may use and manufacture my invention, I will proceed to describe its operation and construction.

In the accompanying drawings, which make a part of this specification, Figure 1 is a plan View. Fig. 2 is a bottom view.

In Fig. 1, A is the beam, B the handles, 0 the mold'board, D the share, E the point. 0 o are bolts passing through the handles. 0 is a tap 011 end of bolt 0, for keeping'it in its place. 'i is a stay for the handles.

In the two figures corresponding letters designate like parts.

In the construction of this plow the moldboard, share, point, and handles are made as may be most convenient and desirable.

The beam (it will be seen by referring to the drawings) to the landside of the plow stands out from the plow abruptly and then runs to its end in the direct line of draft. The end of the beam, however great the divergency at the point x, must be in a line with the point B. The beam and landside in this plow are made in one piece, for the sake of economy and strength. The bolts 0 0 pass through stay i,

handles B, and into the metal of the landside, for the purpose of holding the handles in their places. a is a mortise projection for holding the ends of the handles. The handles are very easily adjusted by means of the bolts 0 0. When a handle is broken the tap 0 may be removed, the bolts 0 0 taken out, and a new handle put into its place.

In the operation of this plow the power is applied, as usual, to the end of the beam. The plow, however much curve the beam mayhave, will follow in the direct line of draft.

Thepeculiar advantage arising from this form of beam is that the plow is entirely prevented from choking or clogging. When the beam stands directly over the point of the plow it is always liable to clog. In this plow weeds, straw, and every clogging substance passes around the beam and is turned over by the mold-board.

The beam may be set out from the plow from nine to twelve inches to elfectualiy prevent clogging.

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

The construction of the beam, as described, in combination with the landside, when the said beam is cast in one piece with thelandside, in the manner described, and for the purposes set forth.

ROBT. B. WINSTON.
