IMPROVEMENT lN PLOWS.

Specification forming part of Letters Patent No. 32,666, dated June 25, 1861.

To all whom it may concern:

Be it known that I, \/VILLIAl\/I LAPE, (.f the city of Troy, in the county of ReHSStl'rltl and State of New York, have invented a certain new and usefullmproved Plow; and Idohereby declare that the following is a full and exact.

description of the same, reference being bad to the annexed two sheets of drawings, in which the same letters of reference indicate like parts in all the figures.

On Sheet I, Figurel is a side elevation ofone of my improved plows. Fig. 2 is a plan of the same plow turned bottom side up, and showing a partial or horizontal section at or near the line ea in Fig. 1. Fig. 3 is a partial transverse section at the line y 3 in Fig. 2. Fig. 4: is a partial transverse section at the line w w in Fig. 2. Fig. 5 shows the inner side of the Fig. 6 shows the parts of the united share, moldboard, and beam against which the landside is fastened. Fig. 7 is a plan ofascrew-bolt and not by which the landside is secured to the united share, mold-board, and beam. Fig. 8 is a view of the outer side, and Fig. 9 of the inner side, of that part of the beam to which the united share and mold-board and the landside are secured. Fig. 10 is a View of a part ofthe inner side of the mold-board with the share attached, and Fig. llis a plan of the bolt by which the united share and mold-board are secured to the beam. On Sheet 11, Fig. 12 is a plan, Fig. 13 a side elevation, and Fig. 14 a frontelevation, all on a larger scale than the other drawings, of that portion of one of my improved plows which acts upon the soil.

The parts of myimproved plow are constructed and united together as follows, to wit:

The stock, or that part to which the landside A and the united share B and mold -board 0 are secured, is cast of cast-iron in one piece with the draw-beam D, and the beam is cast with a wider and deeper double flange, a, on its lower or shorter edge than the double flange b 011 its upper or longer edge, whereby the twofold obj ect of preventin g the beam from shrinking unequally, and consequently from straining, warping, or breaking while coolingin the operation of casting, and of secu'rin g the greatest quantity of strength of metal in that part of the beam which is subjected to the greatest strain when the plow is in use, is at once accomplished.

The share B is formed with a flange, e, an

inside lug,f, and shouldersg g g, Sheet II, and is fitted to and fastened by a screw-bolt, h, and nut h upon the correspondiugly-recessed forward part of the mold board 0, all subs-tam tially as indicated by the annexed drawings.

The moldboard O is united to the beam 1) by means of the rib or flange t, Figs. 2, 4, 8, 9, caston the beam and insertedin a recess formed by the lug j near the lower end, and the long flange or flanges L, Figs. 4, 2, and 10, both cast on the mold board, in connection with the shoulders M, respectively cast on the moldboard and the beam, and with the bent screwbolt m and its nut in, that bolt being passed through an aperture in the mold-board and a lateral slot, m in the rib '1', and the mold-board and beam being braced apart at their rear ends by the bars E E, Fig. 2, just inserted in or through and ex tending between the handles F F, which are respectively secured to the beam and to the mold-board by means of screw-b0lts n a, and screw-nuts a a, and a stud, 0, and loops 0'0 respectively cast in or upon the moldboard and beam, the whole being shaped and arranged substantially as shown by the annexed drawings; and while this fastening is strong enough, it is at the same time a little yielding, to lessen the liability of breaking the parts by rumiing against fixed rocks or stones in the ground, and the lugj is so immovable and is so shaped and projectsdownward so little, and the screw-nut m and the brace E are so high above the base of the plow, that it is hardly possible that the plow can become clogged or that those partscan be broken or loosened by contactwith any projecting stones which may be in the furrow under the plow.

The removable landsideAis secured against the depressed part 19 and shoulder q of the beam (and against the shoulder r of the moldboard and the flange 0 of the share, so as to thereby help support the share and mold-board) by having the rear end, 8, of the beam or stock beveled on its inner side, (see Figs. 2, 6, and 9,) and also inclined forward as it rises, (see Figs. 8 and 13,) and a correspondingly-inclined lug, t, cast on the inner side of the landside and fitting over the doubly-inclined parts of the beam, as shown by Figs. 2 and 13, there being also a screw-bolt, "u, and nut to to clamp the forward part of the landside to the beam,and the whole being shaped and arranged substantially as shown by the annexed drawings.

This mode of attaching the landside is very cheap, and allows the landside to be removed by merely unscrewing the one nut, to, and is at the same time held more securely than if it was attached by two screw-bolts alone, or by wooden wedges inserted in dovetailed recesses formed by lugs cast on the inner sides of the landside and stock in the common way.

The landside A has a flange, r, Fig. 5, east along the inner side of its base, so as to give the plowa firm bearing without making it draw as hard as it would if the flange were caston the outer side, so as to wedge into or against the unplowed ground.

By having the landside extend back to or nearly to or past the rear end of the moldboard, as shown by Figs. 2 and 13, the plow will generally run much more steadily than if the landside were much shorter than the moldboard.

The length width, inclination, and form of the upper or acting surface of the share B and mold-boardO united are in a degree indicated by Figs. 12, 13, [4, and other of the drawings,

\ and is such that the shareand moldboard will cut loose, lift up, and turn over an ordinary sod without either breaking it or crimping it up in heaps,so thatthe plowdraws easier than most if not all of those in common use, and is particularly well adapted for cutting and turning over a tough sod, or one of many years standing.

Havingithus shown and described the manner of constructing the several parts and of attaching them together in my improved plow, I wish it understood that I do not herein claim as new any of those parts or modes independent of the rest; but I do not know or believe that a plow having all of the above-specified features was ever known or used before it was made or invented by me.

What I claim as new and of my invention, and desire to secure by Letters Patent, is

A plow having its landside A, shareB, moldboard O,and beam D allconstructedand united together in the manner herein shown and described.-

WILLIAM LAPE.
