IMPROVEMENT IN PLoUens.

Be it. known that I, GILPIN MOORE, of Moline, in the county of Rock Island, and State of Illinois, have invented certain new and useful Improvements in Ploughs; and I'do hereby declare that the following is a full, clear, andexaet description thereof, reference .being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts, wherever they occur. i A' To enable others `skiiled in the art to construct and use my invention, I will proceed to describe 1t.

My invention consists in a novel method of constructing ploughs having iron beams, so that the beams may be adjusted laterally as desired. I

Figure 1 is a top plan view of a plough constructed on my plan.

Figure 2 is a transverse section, taken on the line a: n: of iig. 3, and enlarged, the better to illustrate the invention.

Figure 3 is a rea-r elevation of the plough, as constructed. In constructing my plough, I use a, cast-iron frame or staiidard, C, to which the shal'c,mouldboard, and

I construct a. curved iron beam, B, which is secured to the upper portion of frame C by a bolt, t, which passes transversely through both, as shown in figs. 2 and 3, the rear end of the beam B being Acurved downward, an 4 which tits into a. hole in the brace E, as represented at e, of iig. 3. InAthe inner side of the standard C, near its upper end, a horizontal recess or slot is formed, in which I place a bolt, D, having an inclined projection on its side, as shown in fig. 2, the bolt lying in the recess, between the standard C and the beam, with the inclined projection at the front. On the rear end of this bolt or wedge D, I out a screw-thread, and fit thereon a nut,

d terminating in a journal or rounded stem,

'a, as shown in figs. 1 and 2, the rear end of the bolt D projecting through a hole inl the rear edge ofthe standard C, against which the nut a bears. When thus constructed, it will readily be seen that by loosening the nut on bolt t, and screwing up the nut a, the wedge or boltD will be drawn back, and thereby crowd or throw the front end ,of the beam over from the land, as indicated in red in fig. 1, and byreversing the operation it may be thrown to the land. By these means the beam can be'adjusted more or less, to any degree desired. It

is obvious, that instead of the nut a, a key may be used, with washers for adjusting the bolt D, but I prefer the nut, as heilig the simplest and best.

Having thus described my invention, what I claim is- 1. A movable wedge-bolt, arranged to operate :is-described, for adjusting the beam of a plough laterally, substantially as set forth.

2. A cast standard, having a slot or. recess formed therein to receive the movable wedge-bolt, and used in combination therewith for adjusting the beam of a plough, substantially as described.y
