IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 101,964, dated July 5,1870.

To all whom it may concern:

,Be it known that I, JOHN LANE, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in the Manufacture of Plow Standards; and I do hereby declare that the following is a full, clear, and exact drscription thereof, reference being bad to the accompanying drawings, making part of this specification, and to theletters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, I wi.l proceed to describe it.

The nature of my improvement consists in making the plowstandard with a projecting strengthening-rib on the side of a flat-bar upright, and a crooked coupling bar orlug, which is bolted to the under side of the share and mold-board, which bar or lug is welded to the upright above the mold board, substantially as herein set forth and described.

Figure 1 gives a view of my improved plowstandard, of which A is the upright, which is a fiat bar of iron having a rib on one side, as shown. Fig.2 gives across-section view taken on a line, a: w, in Fig. 1, showing the projecting rib a, which gives additional stiffness to the thin bar of iron.

B in Fig. 1 shows a crooked bar of iron, which I call coupling-bar. To itare bolted the share and mold-board, and the upper part, which is above the mold-board and extending to the top of the standard, is bentupright, and is welded to the side of the upright A. This crooked coupling-bar also acts as a brace, giving strength to the plow, and, being welded to the upright A above the mold-board, gives additional stiffness and strength to the standard. I-sometimes make the coupling-bar as a short lug.

Fig. 3 gives a view of the plow standard with a lug, O, and shows how it differs from coupling-bar B by being short, and to which the mold board only is bolted, while the bar B extends under both mold-boardand share.

Fig. 4 gives a view of the plow-standard at tached to the plow. Isometimes welda brace to the back edge of the standard and bolt the top end of the brace to the under side of the beam, as'shown by K.

I do not confine myself to the useof a ribbed standard, as shown, when using my improved coupling-bar B or lug O, as a flat bar or any pther shaped bar may be used in combination with the bar B or lug O as I make them.

I am aware thatit has been common to weld ashort lug on the front edge of a plow-standa rd to be bolted to theback of the mold-board;

but I am not aware that thelug was ever bent upright and welded to the side of the standard above the mold board to give additional strength and stiffness to the upper part of the plow-standard.

Having thus described my invention, I claim-- 1. A plow-standard, which consists of aflat bar stiffened and strengthened by a projecting angle-piece or rib, when made in one piece and arranged substantially a shown.

2. The uprightA and bar Bo'r lug O, welded together above the mold-board, substantially as shown, and for the purpose set forth.

3. The crooked coupling-bar B, Welded to the upright ot' a plow-standard and bolted to the mold-board and share, substantially as shown.-
