PLOW.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed June 10, 1908. Serial No. 437,748.

To all whom it may concern:

Be it known that I, Trronxs D. SIMS, a citizen of the United States, residing at Fayetteville, in the county of Lincoln, State of Tennessee, have invented certain new and useful Improvements in Flows; and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to plows, and has for one of its objects to improve the construction and increase its efficiency and utility.

Another object of the invention is to provide a simply constructed plow wherein the several parts are more firmly united without materially increasing the expense of construction or the weight of the structure.

\Vith these and other objects in view the invention consists in supporting members applied to the opposite sides of the rear lower portion of the beam to reinforce the same and form a foundation for the reception of the mold-board or point, and at the same time provide means for supporting the lower forward ends of the handles, and thereby dispensing with the necessity for employing diagonal brace rods which serve to obstruct the free action of the plow and cause it to become choked by grass and trash.

The invention further consists in certain novel features of construction as hereafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention.

Figure 1 is a side elevation of the improved plow. Fig. 2 is a front elevation with the beam in section on the line 22 of Fig. 1. Fig. 3 is a bottom plan view. Fig. at represents the reinforcing blocks detached and in perspective.

The improved device may be applied to any of the various metal plow beams which comprise the draft portion 10 having the clevis 11 at the forward end and curving downwardly and forwardly at the rear end as represented at 12 and forming the standard portion of the beam. Bearing upon opposite sides of the standard portion of the beam are two blocks 131 1 preferably of wood, and inclining rearwardly and upwardly, the lower ends of the blocks being beveled so that they extend in a longitudinal plane as at 15 and even with the lower end of the standard portion of the beam.

The blocks 1314 are connected to the beam by a transverse bolt 16, while the handles represented at 1718 are bolted at their lower ends to the outer faces of the blocks by the same bolt 16, while another bolt 19 extends through the handles and likewise through the rear upper ends of the blocks. The handles 1718 diverge rearwardly and are inclined upwardly and spaced from the rear ends of the blocks 1314:, and surrounding the bolt 19. between the blocks 13-14 and the handles are spacer ferrules 2021, so that the handles are supported in position relative to the blocks. The handle members 17-18 are connected near their rear ends by a cross bar 22, and likewise supported from the beam by diagonal braces 23-2 1.

The blocks 1314 are reduced at their forward ends and form shoulders 2526, and fastened to the upper faces of the blocks in advance of the shoulders or bearing upon the blocks in their reduced portions is the point 27 of the plow structure, this point portion bearing at its rear end against the shoulders 2526 and secured in place by a heel bolt 28 extending through the point and likewise through the lower end of the standard portion of the beam.

By this simple means a very strong and durable plow structure is produced which materially stiffens and strengthens the beam and supports the point and prevents the displacement of the latter by contact with the ground, or any obstructions therein which it may engage.

The space between the point and the beam is entirely unobstructed except for the face of the standard portion 12 and the forward faces of the blocks 13-14 so that grass and trash will not be liable to be caught by the plow in its action and thus retard its movement.

The rear end of the point 27 bearing against the shoulders 25-26 of the blocks 1314, the latter receive the rearward strains of the point and effectually resist its displacement when subjected to the strains incident to its progress through the soil, and thus relieve the heel bolt 28 largely from strains. This is an important feature of the invention and adds materially to its utility and efficiency.

A spacer block 29 is disposed between the rear upper ends of the blocks 13-14 and likewise rearwardly of the standard portion 12 of the beam and through which the bolt 19 passes.

WVhat is claimed, is

1. The combination with a plow beam having a downwardly and forwardly curving standard portion, of blocks having cut away portions at their forward ends whereby vertical shoulders are formed at the rear of the cut away portions, means for connecting said blocks at opposite sides of said standard with the cut away portions even with the contiguous face of the standard and with the shoulders projecting above the surface of the standard, a plow point bearing upon the cut away portions of the blocks and against the shoulders, and likewise hearing upon the standard between the blocks, and means for securing the plow point to the standard.

2. The combination with a plow beam having a downwardly and forwardly curving standard portion, of blocks having cut away portions at their forward ends whereby vertical shoulders are formed at the rear of the cut away portions, means for connecting said blocks at opposite sides of said standard with the cut away portions even with the contiguous face of the standard and with the shoulders projecting above the surface of the standard, a plow point bearing upon the cut away portions of the blocks and against the shoulders and likewise bearing upon the standard between the blocks, means for securing the plow point to the standard, a filler member between said blocks rearwardly of the standard, handles bearing upon opposite sides of said blocks, and a clamp bolt extending through the handles, blocks and filler member.

In testimony whereof, I aflix my signature, in presence of two witnesses.
