IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 29,162, dated July 17,1860.

To all whom it may concern:

Be it known that I, LOURE. GREEN, of Great Bend, in the county of Susquehanna and State of Pennsylvania, have invented certain new and useful Improvementsin Plows; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Similarletters refer to similar parts throughout.

Z is the mold-board; Y, share Q, landside, and X, standard.

The nature of my improvement consists in constructing and combining the several parts of the plow, as hereinafter set forth.

My plow is constructed and operates as follows:

Figure 1 is an elevation, showing the moldboard and share. A H E F 9 show the outline of the share, and H F J B P S L that of the mold-board, A 9 being the concave cuttingedge of the share, having its greatest depth of five-eighths of an inch at m. The dotted line P P shows the point at which the furrow is ready to be thrown over. The cutting-edge of the share is shown in the same figure from A to L, rising at an angle with the base-line of thirty degrees. By reference to the drawings it will be seen that the face of both the moldboard and share is convex instead of concave, giving the plow a wedgelike form.

Fig. 2 represents theinner side of the moldboard, with the head and neck piece attached and the landside and share removed, showing also the head-piece by which thelandside is attached. The head and neck piece stand off from the board at the proper angle to receive the landside on its face V, and are made firm by two bolts, 11 b. C is the cap that holds together the angles of the neck. Through this is a mortise which receives the sheth or standard WV. This standard is made of wroughtiron, and is attached to the bolt 7), and passes up through the beam which rests on the cap 0, and is secured by a nut above the beam.

Fig. 3 represents the landside completed, the lower edge being concave from A to L, as shown. On the lower edge there is a flange cast, projecting a little on each side, commencing at the nose-piece and increasing in width toward the end. This flange is shown in the detached view of the landside-piece in Figs. 6 and 7, the first showing the inner frame and the latter the outer frame. This flange is shown in part in Fig. 5.

Fig. 4. shows the reverse side of the share, which is to be attached to the mold-board by two bolts, m m, and also a socket at Rand lock at f. J is a cap that projects from one-half to three-fourths of an inch over the edge of the mold-board, as seen at i 2', and connecting smoothly with the face of the landside, as at R d in Fig. 3. D E is the sole of the share, and Rf the line of connection with the lower edge of the mold-board, the point being round at S and formed with an edge from S to K, similar to the edge from K to D. The figures marked on the various lines show their pro portionate measurements.

Fig. 5 is a view of the sole or ground plan of the plow. This shows the degree of inclination or angle of the cutting-edge of the share-in other words, the spread of the plow. The line rfg wis the cutting-edge of the share and the line a, b the landside. W P shows the curve of the mold-board from the heel of the share to the line P P. (Thislineis shown in Fig. 1.)

Fig. 8 represents the head and neck piece, which is separate from the mold-board, but is seen in one piece with the mold-board, as in Fig. 2. At a the head-piece is set back beyond the true face of the neck the thickness of the landside, so as to form the neck andlandside in one true face.

As the plow may be made of a variety of sizes, the figures marked on the drawings are only intended to give the proportionate dimensions of the various parts.

By reason of the gentle rise of the cutting edge of the share, together with the like gentle spread of the share, the sod is cut and lifted without being broken, and its pressure being greatest on the fore part, the nose is thereby keptdown. Thegentlespreadofthesharealso gives great ease of entrance into the ground, and at the same time diminishes the pressure on the landside, producin g an easy draft, whereby the plow, when once entered in the furrow, will keep upright and continue to run at full depth without extraexertion by the attendant.

The concavity of the sole has the effect of The arrangement and combination of the clearing the nose or point and letting it conmold-board Z, share Y, landside Q, and standstantly run below the general level of the furard X, the Whole beingeonstrneted as and for row, thus obviating the danger of being thrown the purposes herein described. up by obstructions.

What I claim as my invention, and desire to secure by Letters Patent, is

Witnesses LOURE GREEN.
