SPECIFICATION forming part of Letters Patent No. 735,297, dated August` 4, 1903.

Application filed October 16, 1902.

To a/ZZ whom tw/Lay concern:

Be it known that 1,1LUCIUs R. RANDALL, a citizen of the United States, residing atElza, in the county of Tattnall and State of Georgia, have invented certainnew and useful lmprovements in Shovel-Plows; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable'others skilled in the art to Whichit appertains to make and use the same,reference being had to the accompanyingdrawings, and to the gures of reference marked thereon, which form a part of this specification. j

This invention relates to shovel-plows de` signed particularly for cotton cultivation. Its objects are, first, to generally improve the construction and adjustment of such plows; second, to provide a novel means of attaching the sweeps to the standard; third, to improve the sweep and heel adj ustment.V

With these and other objects in view the invention is hereinafter described, and is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the plow. Fig. V2 is a front view of the plow-standard, the moldboard and point being removed. Fig. 3 is 'a sectional view of the moldboard and plow-point. Fig. 4 is a sectional view of the sweep. Fig. 5 is a vertical section of the heel, showing the spring-latch arrangement for holding the sweeps to the heel; and Fig. 6 is a top view showing the beam connections.

Referringspecificallyto the drawings, `6indicates the beam; 7, the front standard 7 a,the rear standard; 7b, a brace for the rear standard, extending therefrom to the cap-piece 7c. at the top of the front standard, and 8 the' handles bolted to the rear standard by bolts 8, which pass through slots (indicated at 7d) in the rear standard, so that the handles can be raised or lowered. On. the under side of the beam is a convex bearing-plate 6, fitting a corresponding concavity in the cap-plate' 7c, which is joined to the beam by a bolt 6?. A joint is thus formed between the beam and the cap-plate, whereby the beam can be adjusted vertically and laterally with respect to the standard. The hole through which the bolt passes is therefore enlarged, as indicated in dotted lines. The rear end of the beam Serial No. 127147Z. (No model.)

`iits in a box-casting 9, which basa ilangeia,

forming a lap-joint with a vertical flange 10EL of a coupling-piece 10. The meeting faces of the lianges are held together by a bolt 9b. One of the iianges, preferably that of the coupling-piece, is slotted, as indicated in dotted lines at 10, to permit desired vertical movement or adjustment.

The coupling lO is joined to the top of the rear standard 7 a by a bolt 10b, and the coupling rests on a transverse horizon tal shoulder 7 e, formed 'on the rear standard.- Lateral adjustment is edected by slotting the coupling 10 horizontally, as indicated at 10G in dotted lines, Fig. 6, the bolt 10b passing through the slot.

The moldboard is indicated at l1, formed in one piece, and the plow-point at 12. They are 7o secured to the standard in the following many ner: Thelower end of the standard 7 is anged or liattened,as at 7 f,which portion has socketholes 7g for lugs 11a and 11b and 12a and 12b on the back of the moldboard and plow-point, respectively. The lugs 11a and 12 are hooked, as shown, and the hooked portions' engage under the standard. The lugs 11b and 12127 are notched, as shown, to receive the bolts 7h of simple spring-latches (indicated at 7i) on the 8o back side' of the standard. By this construction the'plow-point or moldboard may be readilyattached or detached and when attached are securely heldin place without the use of'bolts or loose parts. 85

The lower end of the standard has a branch 1,3a to form a support for the heel 13, to which it is joined by a pivot-bolt 13b. The parts are halved and lapped, and the meeting faces have. radial -corrugations, as indicated in 9o dotted lines. The heel carries the sweeps 11i and is adjustable verticallyon the pivot-bolt to vary the height of the sweeps. The sweeps are attached tothe heel by means similar to those shown for attaching the moldboard to the standard-that is, the sweeps have a hooked lug 14a, which enters a socket 13c in the heel, and a notched lng 14C?, which enters a socket 13d in the heel, with a spring-latch l 13e engaging the notch. The latch-bolt can roo `be depressed and withdrawn to permit removal of the sweeps.

To keep the slide of the plow level irrespective of the adjustment of the heel 13, said heel is provided with a shoe 15, having a vertical fiange lpand joined to the heel by a a pivot-bolt 15b, the adjustment being fixed by a bolt 15, which passes through a slot in the fiange 15a.

By the construction shown the plow-beam can be adjusted as to side draft or to make the plow run shallow or deep. The moldboard, point, and sweep attachment is simple and eective and permits quick change without tools. The sweep adjustment is useful to accommodate local conditions.

What I claim as new, and desire to secure by Letters Patent, is-

l. Thecombination with the standard, of the heel adj ustably connected thereto and LUCIUS R. RANDALL.
