SHOVEL-PLOW.

SPECIFICATION forming part of Letters Patent No. 265,324,dated October 3, 1882.

Application filed July 1, 1880.

To all whom t may concern Be it known that I, WILLIAM O. JOHNSON,

a citizen of the United States, residing at Alma, in the county of Gratiot, Michigan, have iuvented a new and useful Improvement in Shovel-Plows, of which the following is a specification.

This inveution relates to those shovel-plows for oultivating the soil which are made adjustable to adapt them to different conditions of ground and the requirements of different crops, and to adapt them to be readily controlled by the plowman.

My present invention. consists in certain novel combinations of peculiarly constructed and arranged parts, as hereinafter described and claimed.

Figure 1 of the accompanying drawings is a perspective view of a shovel-plow illustrating this invention. Fig. 2 is a front view of the same; Fig. 3, a side iew, and Fig. 4: a plan or top view.

Like letters of reference indicate corresponding parts in the several figures.

The share-standard A is attached at the rear extremity of a long pole-bea m, B, by a pair of side plates securely bolted to the latter, a horizontal bolt or rivet, a, passing through the standard and side plates, so as to form a loose or hingejoint.

At a proper distance in front of the standard A the whiffletree-clip E is bolted to the top of the beam, and its permanent bolt or bolis are made to pass through and attach a perforated sector-bracket, b, which projects rearwardly beneath the beaun.

To the lower end of the standard A the shovel or share EI is attached by two or more bolts, one of which is an eyebolt, c, and from this bolt to the bracket b a braco, F, extends, being connected thereto, respectively, by bolts a a The brace F is by preference double,

or composed of parallel thin bars, so as to dis tribute and equalize the severe strain on the bolts a a and thus avoid frequent breakages, and also to facilitate its use for supporting a colter, D, which passes between the parts of the braco, and is secured at its upper end by a wed ge, d, or its equivalent, within a vertical mortise in the beam B, andat the brace F by (No model.)

a pair of bolts, e e, passing through the latter in front of the colter and behind it, as shown. Provision is thus made for setting both the sharestaudard and the colter at different angles by the same means, while the independ ent vertical adjustment of the latter is not interfered with, and all the parts are adapted to sustain any strain to which they can ordinarily be subjected. I do not limit myself to the use of a double braoe in the accomplsh- .60 ment of these results, as a single brace could be employed.

A pair of handles, C O, are attached to the ends of a pivotal cross-bar, f, near the upper end of the standard Aand converge therefrom to a standard, Gr, of wedge-shape in cross section, and having a vertical series of. holes to receive ascrew-bolt, g, by which the front ends of both handles are clamped to said standard G at any desircd height, so as to raise and lower the rear ends of the handles,or the handles proper, to make them suit the plowman. The front ends of the handles are slotted, as shown, to aocommdate the bolt g in its dif ferent positions. A slot may take the place of the vertical series of holes in the standard Gr, if preferred. The standard Gr is itself adjusted as to angie when the angie of the standard B is changed. To provide for this adjustment the lower end of the standard G is rounded, as shown in dotted lines in Fig. 3, and fasteued by a transverse pivotal bolt, which may be loosened and retightened at will.

The beam B may be short, and provided with a clevis at its extremity, instead of be- 85 ing adapted to extend through the neck-yoke of ateam, as represented; and the eyebolt c may be located above the share H, so as to facilitate removing the latter, if preferred.

I do not claim broadly a hiuged share- 0 standard with an adjustable brace to govern its pitch, nor handles adjustable as to height; but I know of no anticipation of my improved means for adjusting the share-standard and handles and iastening them in their respect- 5 ive positions, as hereinafter claimed.

Having thus described my said invention,

I claim as new and desire to protect by Letters Patentl. The combination of the share-standard roo A and beam B, united by {L hinge-joint, and provided respeetively with the eyebolt 0 and sector-bracket b, the latterhaving a series of ndjusting-holes, und the diagonal brace F, united to said eyebolt and brucket by screwbolts, and composed of pztrallel flat bars, whereby the strnin on said bolts is equalized, and a volter-socket is formed below the beam, as herein specified.

2. The combination of the share-standard A and bemn B, united by a hinge joint, and provided respeetively with the eyebolt c and sector-bracket Z), the letter having a series of adjusting-holes, adiagounl bruce or braoes, F, united to said eyebolt and bracket by screw bolts, and a colter, D, fustened at its upper end within u vertical mortise in the bean1 P, and supported below the bezun by said brace or bruces F, whereby the shovel or share and the colter may be adjusted and supported us projecting upwztrd between the front ends ol the hztudles, and united with the letter by a verticallyadj ustable elamping-bolt, g, substantially es shown, for fnstening the handles at difierent heights iudepeudently of the pitoh of the shmestundanl, in the manuer set forth.
