FRANCIS M. FRANKLIN, OF SPRINGFIELD, OHIO, ASSIGNOR TIO HIM'- SELF AND EDWARD M. DOTY, OF SAME PLACE.

Letters Patent No. 91,109, dated June 8, 1869; antedated May 24, 1869.

IMPROVEMENT 1N FLOWS.

The Schedule referre to in these Letters Patent and making part of the same.

To all whom tt may concer/n:

' Be it known that I, FRANCIS M. FRANKLIN, of Springfield, in the county of Clarke, and in the State of Ohio, have invented certain new and useful Improvements inPlows; auddo hereby declare that the following is a full, clear,'and exact description thereof', reference beinghad to the accompanying drawings,

The'nature of my invention consists in the construction of' the sheath to a plow, and in the ma'nner'of attaching lthe plow-beam to the handle.

In order` to enable others skilled in the art to which my invention appertaius, to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, which form a part of this specification, and in which- Figure l is a side view, and Figure 2, a front view.

A represents the plow-beam, B, the handle, and C, the sheath, to'which the plow D is secured, said plow The sheath' C is of the usual length and size, of round wrought-iron, vertical, with a forward curvature.

At the height of about eleven inches it bends out from the line ofthe beam; then, at the additional height of about five inches, it has a right angle, bent across the line of the beam. This horizontal part of the ysheath.I term a knee; it is about four inches long. 4The beam rests on about three inches of the knee, and the projecting inch is flat, and has a hole through it,

The front of the dra ght-rod F has aneye, for a ring, G, and back of said1 eye, for a suitable distance, the draught-rod is dat, and secured to the the beam A by one or more screw-bolts.

The rear end passes through an eye in a bolt, H, which passes up through the beam just in front ofthe knee on the sheath C.

The draught-rod F has a bend just back of `said knee, and passes up through thebeam. Ihus the rod F and bolt H, each having a washer and nut, form a stirrup, to keep the beam rm to the knee.

By this arrangement the draught-rod becomes a support to the beam in a greater degree than can be obtained by any former model of attachment, thus gaining the advantage at this point of adding the. power of tension to the strength of the beam, through the medium ofthe angle.

point of l level of the knee, an upright, I, is attached by screw- Upon the handle B, at a proper distance below the bolts.

The lower end of the upright, I, is flat, and the bolts pass through holes in that part, to secure it to the handle. Just above the flat part, the upright angles, incline alittle forward; A screw is cut on theupright, to the height of about five inches.

A nut, a, is ruu down to 4the flat, and the upright passes up through a hole asuitabIe distancev from the rear end of the beam.l The direction of this hole, and the position of the upright should be decided by a tram pivotedon the centre ofthe knee;

The uprivht, I, projects above the beam, to receive a washer an( nut, b.

Above the nut b the upright is reduced in thickness, and passes through the end of a forked brace, J, and has a nut, c, above said brace.

The forks of the brace J extend back, one passing on each side of the beam-handle B, and have holes in their rear ends, through which anirou round, L, passes, Y' going also through both handles, and through two thimbles, d d. i

rlhe thim'bles dd are bell-shaped, and place-dhctween the handles and the ends ofthe brace, the large ends against the handles, and the smaller, outer ends, against the brace. The thimble and brace between the handles are pressed against the handle by a iirrn washer, e, ou the rouudL; those outside are kept to s the handle by a nut, f, on the end of the round.

It will be seen, that by.raisng or lowering the rear end of the beam A, on the upright, I, by means of the nuts a and b, the heightof the plow is easily regulated.

`Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-`v i f 1. The bent sheath C, constructed and lused substantially as and for the purposes as herein set fort-lnV 2. The arrangement of the beam A, sheath C, bent draught-rod F, eye-bolt H, upright, I, and handle B,

all substantially as shown and described.

3. Ihe arrangement of the handle B, -upright, I, round, L, forked brace J, thiuibles d d, washers e c, and nuts c and f j, all substantially as herein set forth.

In testimony that I claim the foregoing, I have hereunto set my hand, this 30th day of May, 1868.

. FRANCIS M. FRANKLIN.
