Specification of Letters Patent.

Patented April 2, 1907'.

Application filed June 5, 1906- Serial 1105320553:

T0 (0% whom it may concern:

Be it known that I, ALoNzo R. MALLORY, a citizen of the United States of America, and a resident of Atlanta, in the county of Fulton and State of Georgia, have made a certain new and useful Plow-Stock; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

The object of the invention is the adjustment of the foot or standard of the plow on the beam thereof in such a manner that a one or two horse plow may be provided and the share secured to said foot may be made to enter the ground at any angle desired, so as to plow deep or more shallow at will.

The invention consists of the device hereinafter set forth as claimed in the annexed claims.

The invention is shown in the accomp anying drawings, as follows: Figure 1 is a side elevation of the device. Fig. 2 is the plan thereof, and Fig. 8 is a side elevation of the beam proper. Fig. 3 is an edge view of said beam. Fig. 4 is a side view of the foot, and Fig. 4. is a plan thereof, showing the pair of bars forming same. Fig. 5 is a side view of the supplementary foot. Fig. 5 is a back view thereof, showing the inturned forward ends; and Fig. 5 is a plan thereof. Fig. 6 is an end view of the landside and heel-plate. Figs. 6 and 6 are respectively inverted plan and side views thereof. Fig. 7 is a detail in side elevation of the means for attaching the forward end of the foot to the beam, and Fig. 7 is a sectional detail thereof. Fig. 8 is a plan view of the shackle for securing the front end of the foot to the beam. Fig. 8 is a side view thereof from the direction of the back end of the plow, and Fig. 8 is a side elevation thereof.

In these figures like reference characters are uniformly employed in the designation of corresponding elements of construction in all the views.

a is the beam, which is preferably made of a single bar of metal curved downwardly at its back and perforated with a bolt-hole at said back end and provided at its front end with a clevis or other means of attachment.

1) is the foot, which is made of, preferably, two bars curved upwardly at their front ends and downwardly and forwardly at their back ends, a series of holes being provided at their front ends substantially at a right angle to the main body of said foot, while the back end is provided with holes for the rivets securing the landside c and the block at, said block at projecting a short distance backwardly from between said bars, so as to form a bearing for the nut of the heel-bolt. (Common, and hence not shown.) Intermediately are holes for the braces e and the supplementary foot f.

g is a heel-plate secured to the under side of the landside c.

The supplementary foot f consists of a curved structure formed of two bars bent convergently and joined at their front ends, the curvature thereof being such that it will lie approximately parallel in corresponding members with the foot proper, I), being pro vided at its joined front end with a hole for the purpose of a bolt passing through the two members of said foot I) and said supplementary foot and its lower end being provided with a hole to secure it to the landside c, as shown in Fig. 1. Intermediately, it is provided with a series of holes for the attachment of the lower ends of the handles h, and just above these holes is another series of holes, to which, by a suitable bolt, may be secured the back end of the beam (1 adjustably. The handles h are otherwise secured by the braces 6, being bolted thereto, said braces being otherwise, as shown in Fig. 1, pivoted to the foot I). These handles are adjustable as to height by moving their bolt of attachment from one of the series first named of holes in said supplementary foot to another of said holes.

i is a shackle, which consists of two parallel plates 7', joined by a crossbar, which in use lies across the lower side of the beam, with said plates substantially in contact with the sides of said beam, 7c being outwardlyprojecting flanges adapted to engage the edges of the forward upturned ends of the foot I) with the upper ends of said side plates, being provided with holes through which (and the holes in said upturned ends) is passed a bolt securely clamping said shackle on the beam and locating the forward end of the foot b against movement relatively thereto. Thus it will be observed that a truss structure is provided for the beam and foot of extreme rigidity and strength, and at the same time adjustments may be made of the front end of the foot upon the beam. and the back end of the beam along the supplementary foot, so that any desired working angle of said foot to the line of draft may be obtained without detracting in the least degree from the strength and rigidity of the plow.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a plow, a beam and a foot pivotally secured by its front end to same and extending backwardly along said beam and curved downwardly and forwardly at its back end, a supplementary foot secured to said foot a short distance from its back end and curved backwardly and downwardly therefrom, a landside secured to the free ends of said foot and supplementary foot and means for adjustably securing said beam to said supplementary foot.

2. In a plow, a beam curved. downwardly at its back end, a foot secured adjustably by its front end to said beam and thence extending lg backwardly and being curved downwardly and forwardly at its free end, a curved supplementary foot secured to said foot a short distance from the free end thereof, its curved portion lying substantially parallel to the curved end of said foot and being attached to said landside, and means for adjustably connecting the back end of said beam to said supplementary foot.

3. In a plow, a beam, and a curved foot lying along'the under side of said beam and being secured adjustably at its back end to said beam, and its forward ends being upturned and adapted to lie upon opposite sides of said beam, an intervening shackle provided with side plates adapted by flanges to engage said upturned ends and a bolt passing through said upturned ends and through said shackle above said beam.

In testimony whereof I hereunto set my hand in presence of two subscribing witnesses.

ALONZO R. MALLORY.
