IMPROVEMENT IIN Pltows.

Spceilieation forming part of Letters. Patent No. 32,094, dated April 161861.

Salem, in Washtenaw county,A and Stute' of Michigan, have invented a new and useful Improvement upon Gast-Iron Plow-Beams; and I do deel-.ire the' following to be a full and.

exact descriptionthereof, reference being had to the accompanying drawings, and to the letters ot' reference marked thereon. l

The nature of invention and improvement consists in the urrangementot' devices, as here inalter described.

Reference being had to the accompanying drawings, like letters referring to like parte, Fi gnre 1 is the beam, with parts fitted together and 4secured lLy bolts. Fig. 2 is the beam, separated into two parts, marked Bartl land Part 2. Fig. 3 is part 2 inverted te show the face and knuckle on the lnndside of the saine. My improved plow-beam is of east-iron, and consists of two parts', (marked ,Part 1 7 und "Part 2 in Fig.' 2,) so arranged as to be connected in lap-joint A by carrying back part 2 upon pnrt 1, so as to bring together the points C C and I) l), by which means the inner face of the rear end of. part 2 is brought against the flange-bound face F in part I, thel bolt-holes H H H in one part matching corresponding holes in the other parts. The inner face ot' part. 2 is shown at G in Fig. 3, which is part inverted, as abovedescribed. .The two faces being thus put together, the knuckle K in Fig. 3, projecting from thefaceG, fits into the socket L, part 1,Fig. 2. The projection M otpart l lits into .the recess N of p'art 2. The shoulderA C of parti! is brought against C in part 1, and the curved end G D ot part 2 lits against and' Within the corresponding flange C D of part l. 'lille parts being thus put together are secured by bolts passing through holes ll' H 1I, parts land 2, Fig. 2. The bolts are shown at 0 O O, Fig. 1.' Before the bolts are fully screwed up a wedge-shaped' key, B, Fi g. 1, is inserted into the mortise I, by means ot' which the faces G and F may be more or less separated at the back part of the joint, and the angle or position ot' the beam,part 2, adjusted and the dralt regulated accordingly.

A. slight adjustment of the key B making considerable change in the draft without crossstrain ofthe beam ,several horses may be worked abreast with advantage and safety,and by the -arran gementot knuckle projections, and flange a lirin and secure joint is obtained without strain upon the bolts.

f I-do not claim a disjointed benin as such, nor

tlie lap and knuckle joint; but

WhatI do claim, and desire to secure by Let- Thejwedge B, knuckle, K., fitting into the socket L, lla-nge O D, projection M, fitting-into recess N, the

parts

1 and 2, having corresponding faces and boltholes, the whole bein g made, arranged, and devised substantially in the manner and for the purposes set forth and described.
