IMPROVEMENT lN PLOUGHS.

TO ALL WHOM IT MAY CONCERN'.

Be it known that I, S. J. LEACII, of Tuscaloosa, in the county of Tuscaloosa, and State of Alabama, have invented n. new and useful Improvement inIPloughs'; and I do hereby declare that 'the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ofthis speciiication, in which- 'Figure` 1 is an outsideview of the mould-board of my improved plough.

Figure 2 is an inside view of the samc.

Figure 3 is a detail sectional view of the same, taken through the line a: x, g. 2.

Similar letters of reference indicate .corresponding parts. i

My invention has for its object to furnish an improved plough, provided with a detachable facing forme'd of wood or other material, to which adhesive soils (will not adhere and clog the plough, ywhich shall be cheap,

more durable, and more e'ective than the pleughs ordinarily used in such soils; and it consists in facing the' mould-board of theplough with athindetachable sheet or plate of wood, steel, or other suitab''e material, and in forming the mould-board of the plough with a shoulder and slots or socketsto receive the forward edge and tongues of the facing-plate; the'whole being constructed and arranged as hereinafter more fully described,

A is the standard, and B is the mould-board ofthe plough, which may be cast in one piece in the ordinary manner. The'mould-board B is formed with a shoulder, b', formed upon it at the point at which they forward end of the facing-plate should end. The shoulder li should project so far as to equal the thickness of the facing-plate, and should project rearward, so as to form an acute angle withthe mould-board B'. vC are two or more slots or sockets formed in the mould-board B, fer the reception of tongues formed upon the forward end ofthe facing-plate. D is the facing-plate, which is made of a thin sheet or plate of wood, steel, or other suhstance, to which the soil in which thelpleugh is to be used will not adhere.- When the plate D is made of wood, the thin board of which it is formed is steamed and bent or pressed vintothe exact forin of the mould-beard of the plough; and when made of steel, it is swnged into proper shape. The forward edge of the facing-pleite D is so formed as to fit into the inclined or grooved shoulder 6 ofthe mould-'board B, and upon it are formeditwo or moretongues, d', fitting into the slots or sockets C, formed in the mould-board B for their reception, as herein- .Y

before described, so as to render the connection between the facing-plate and mould-board rmer, closer, and more secure than it otherwise would be. The facing-plate D may be secured to the mould-board by screws or bolts 4passing through the said facing-plate and said mould-board, so as to hold all parts of the facing-plate close up lagainst the mould-board. y

By this construction the cast-iron. mould-board oi' the plough supports the facing-plate D, and keeps it in proper-form, and at the same time enables the said facing-plate to beremoved or attached easily, quickly, and conveniently, whenever desired. h

I claim as new, and desire lto secure by Letters Patent- 1. 'Facing the mould-hoard cfa plough with a thin detachable sheet or plate of wood, steel, er other snitable material, substantially as herein shownand described, and for-the purpose set forth. v

2.v Forming the mould-board B oi' a plough with a. shoulder, ,-and with slots or sockets C, to receive the forward edge and tongues of the facing-plate D, substantially as herein shown and described, and for the purpose set forth.
