PHINEAS P. MAST, OF SPRINGFIELD, OHIO, ASSIGNOR TO P. P. MAST & COMPANY, OF SAME PLACE.

OULTIVATOR.

. I SPECIFICATION forming part of LettersPatent No. 361,307 dated April 19, 1887.

. Application filed March 1, 1887. Serial No. 129,317. (No model.)

To aZZ whom it may concern:

Be it known that I, PHINEAS P. MAST, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new anduseful Improvements in Cultivators, of which the following is a specification, reference being bad therein to the accompanying drawings.

On the 27th of December, 1886, Letters Patent were granted to me for improvements in cultivators, and numbered 354,717, in which were shown a cross-head and a beam-bracket of peculiar construction at the point where the two are fitted together.

This invention relates, also, to an improvement in cultivators, having special reference to the construction of the cross-head which carries the shovel-standards and to the beam or beam-bracket to which the cross-head is pivotally connected.

Myinvention consists, essentially, of acrosshead having about midway thereof an opening to receive the-beam or beam-bracket, and provided with enlarged surfaces above and below that opening, and of the beam or beambracket having enlarged upper and lower disk-like surfaces, which fit smoothly against the surfaces of the cross-head, the beam or beam-bracket and cross-head being pivotally connected together.

In the accompanying drawings, forming a part of this specification, and on which like letters of reference indicate the same features, Figure 1 represents a side elevation of aportion of a cultivatonbeam or a beam-bracket, also showing the cross-head in vertical transverse section; Fig. 2, a longitudinal vertical section of the cross-head, showing the beam or beambracket in transverse vertical section. Fig. 3 is a top plan view of the cross-head.

The letter A designates the cross-head, the

1 same consisting of a bar constructed of cast or malleable iron, preferably thelatter,and having at each end beads or shoulders B, to form seats, into which the shanks of theshovel-standards are fitted, one seat being horizontal and the other vertical. In some instances these seats are both horizontal or both vertical or one horizontal and the other vertical, as in the present illustrations. About the middle this bar is divided and an opening formed therein, the upper and lower sides of the bar forming enlarged and substantially flat surfaces, against which the corresponding surfaces of the beam or beam-bracket are fitted. The cross-head is bored vertically to receive a coupling-bolt, upon which it turns back and forth, and by which it is pivotally connected with the beam or beam-bracket. This cross-head is designed to be used particularly with cultivators in which an alignment-rod is used to maintain the parallelism between the cross-head and the axle of the'machine. To this end alug, C, is formed, by preference integrally with the head, to which the rod is connected. The letter D refers to the cultivator-beam, or, more strictly speaking, and accordingto the drawings, to the bracket which is securedto the beam proper, D. When the beam proper is made separate from the bracket, the hub-like portion, presently to be mentioned, is formed on the bracket; but should the part to whichthe handle is secured be formed in one piece with the beam proper, then the hub is formed on the beam. The former constructionis preferred. This bracket consists of a sleeve, F, and a curved arm, F, the former receiving the rear end of the beam proper and the latter connecting with thehandle. Where these parts join, a hub, G, is formed, and the ends of this hub are enlarged to form bearing-surfaces H. The hub is centrally bored to receive the coupling-bolt, and the surfaces H are fitted snugly to the enlarged surfaces of the cross-head, whereby the two parts are fitted together in such manner that the cross-head is merely capable of oscillating on the connecting-bolt, but is held against rising at one end and lowering at the other. In other words, all twisting tendency between the cross-head and the beam is overcome and the parts fitted snugly and held strongly together. This prevents either shovel from rising should it meet an unusually hard patch of ground. The alignment-rod is shown at I, being broken off. 1

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the cultivatorwith enlarged upper and low erends, of a crosshead having an opening therethrough to receive said hub, and enlarged at the upper-and lower ends of said opening to form bearing-surfaces to match with the enlarged ends of said hub, and a bolt to connect the parts together.

2. The eombination,with a cultivator-beam or beam-bracket having a hub whose upper and lower ends are enlarged to form flat bearing-surfaces, of a cross-head having an opening therethrough to receive said hub,enlarged at the upper and lower ends of said opening and flattened at the enlarged portions, whereby the head is prevented from twisting with respect to the hub, and a bolt to pivotally conmeet the parts together.
