IMPROVEMENT IN PLows.

Specification forming part of Letters Patent No. 174,338, dated February 29, 1876; application filed November 23, 1875.

To all whom it may concern:

Be it known that I, JAMES W. WRIGHT, of Wyandotte, in the county of Wayne and State of Michigan, have invented certain Improvements in Plows, of which the following is a specification The nature of my invention relatesto certain improvements in plows; and consists,

' 4 is a cross-section through the land-side and heel at w w, Fig. 1. Fig.5 is a cross-sectionthrough the, standard at g y in Fig. 2. Fig. 6 is a horizontal section of the colter and beam at u a, Fig. 2. Fig. 7 is a horizontal section of the front end of the bealn at 22 in Fig. 2.

in the drawing, A represents theland-side, cast with a recess in the side of its heel to receive a heel-plate, A, east with a shoe, 0., or with one laid on it, which shoe extends'under the entire heel of the land-side, so that, when worn away, a new heel-plate may be bolted onto the land-side or a new heel may- B is the point, cast with a socket, b, to receive the point b of the colter,and with a hole, 0, to receive its pivot'c. O is the mold-board, and- D is the beam which rests upon the top of the landside, which is carried full up to it, to prevent clogging. The heel of.the beam is carried a short distance-up one of the handles, to which it is secured by two bolts. The side of said handle is protected from wear by a metal plate, C, bolted to it, and which maybe considered as a continuation of the laud-side.

, The upper front corner of the land-side is cast with an enlargement, with a square socket, d, cored in it, access to which is had by a slot in the top, through which is introduced. the T-shaped head 6 of a bolt, E, which is- 'the clevis-block is dropped. moidal wooden blocks a are placed between prevented from coming out by giving the bolt a quarter turn. The bolt passes up through a hole in the beam, which is secured in position bya nut, f, by loosening which the beam may be laterally adjusted to give it draft to land or furrow.

F is a colter, having the point b and pivot c to enter the socket and hole in the point, as described. Its shank passes up. througha much larger slot in the beam, and is clamped in position by four stirrups, g, the ends of two of which come through the left side of the beam, while the other two come through the right side, and a washer-plate, h, is slipped over the ends of each stirrup before screwing on the nuts. The nuts can be so adjusted as toshift the upper end of the colter to the right or to the left, the object being to adjust it in the same verticalplane as the land-side. They can be further adjusted to axially adjust the draft of the colter, the object being to have it form a prolongation of the draft-line of the 111161101111 end of the beam in the following manner: A cast-metal plate, H, is bolted to each side of the beam, projecting beyond its end. The inner projecting end of each plate is cast with two vertical ribs, it, into which Enough pristhe plow more pitch, one or more of the blocks are taken from above and placed below the clevis-block.

What I claim as my invention is- 1. The combination, with the beam D, colter F, and stirrups g g, of the land-side A, cast with an enlargement at the, head of the same,'

the slotted socket d in such enlargement, and the T-headed bolt E, whereby the land-side and colter are adjusted laterally and kept in line with each other, the several parts being constructed and arranged substantially as den, and latch I-, for securing and adjusting the scribed and shown. clevis G to the endof the'beam, substantially 2. In a plow, the combination,- with the beam as set forth.

D, of a colter, F, and the four stirrups g, all JAMES W. WRIGHT.
