ATTACHMENT FOR CULTIVATORS.

SPECIFICATION forming part of Letters Patent No. 626,562, dated June 6, 1899.

Application filed November '7, 1898. Serial No. 695,750. (No model.)

To all whom it may concern:

Be it known that I, ALVY G. PERRY, a citizen of the United States,residing at Goldwater, in the county of Tate and State of Mississippi, have invented new and useful Improvements in Attachments for Cultivators, of which the following is a specification.

This invention relates to an improved. attachment for cultivators, and is in the nature of an improvem cut on the cultivator for which Letters Patent No. 495,365 were granted to me on the 11th day of April, 1893. In said patent I show and describe a Z-sha'ped crossbar having a rib or flange along the under side of its rear edge, said bar being adjustably bolted to the under side of the plow-beam and carrying three plow-standards.

It is the object of the present invention to greatly increase the strength of the cross-bar without materially adding to its weightand to afford a firm and secure support and fasteuing for the plow-standards.

To these ends my invention consists in the features and in the construction and arrangement of parts hereinafter described, and particularly pointed out in the claims following the description, reference being had to the accompanying drawings, forming a part of this specification, wherein-- Figure 1 is a perspective view of my improved cross-bar. Fig. 2 is a top planview thereof. Fig. 3 is a top plan view of a cultivator with my improved cross-bar applied thereto. Fig. a is a side elevation of the same, and Fig. 5 is a detail view of a cross bar adapted for two plows only.

Referring to the drawings, the numeral 1 indicates the plow-beam, which may be of ordinary or any preferred construction and provided with the usual handles and draft devices. Bolted to the under side of the beam 1 is my improved cross-bar, consisting of a flat metallic plate or bar 2, which is curved forward, as at 3, to provide an arm, by means of which the forward portion of the cross-bar may be bolted to the beam. As shown, said arm 3 at its extremity is provided with a bolthole 4, and a corresponding bolt-hole 5 is formed in the bar 2, intermediate the ends of the latter. Bolts 0 and '7 are passed through said bolt-holes and through corresponding bolt-holes formed in the beam, by means of which the cross-bar is firmly bolted to the under side of the beam and diagonally to the latter. As most clearly shown in Fig. 2 of the drawings, the end of the arm 3 is connected to the bar 2 by a web or rib 8, said bar, arm, and web being formed in one integral piece. In order to give great strength and rigidity to the bar, I form on the opposite edges of the latter depending flanges 9, said flange extending longitudinally along both edges of the bar and curving around the rear end of the bar, as at 10, and also curving around the opposite edges of the arm 3. A curved flange 11 is also formed on the end of the arm 3 and along the forward edge of the web or rib 8, said flange 11 uniting with and connecting the flange 9 on the forward edge of the bar with the end of the arm 4. As shown, the flanges 9 are of the greatest Width or depth at the center of the bar and taper off toward the ends, and it will be noted that the web or rib S and the flange 11 he in a plane approximately coincident with a line passing through the bolt-holes 4 and 5, thus strengthening and reinforcing the bar at a point and in a direction where the greatest strain is exerted. Said rib and flange also act as a brace or stay for the curved arm 3, which is also strengthened and stiffened by the curved ends of the depending flanges 9. It will be understood that the bar 2 and its reinforcing web or rib and flanges are cast or formed in one integral piece, thus providing a bar of exceeding strength and lightness fully capable of resisting any strains or twisting actions to which it may be subjected in practical use.

At its opposite ends and at a point intermediate its ends the cross-bar 2 is provided with perforations 12, through which pass the upper ends of the plow-standards 13. As shown, the extreme upper ends of said standards which project up through the cross-bar are threaded, and nuts 1 1 are screwed over said threaded ends of the standards for securing the standards in place. The plowstandards immediately below the threaded ends are tapered, as at 15, and in order to afford a firm and broad support or hearing for said tapered portions of the standards I cast annular bosses 16 about the perforations on the underside of the cross-bar 2 and taper said bosses and perforations to correspond to the tapered portions 15 of the standards. When the nuts 14 are screwed up on the standards, the tapered ends of the latter are drawn up tightly into their tapered seats or sockets in the cross-bar, thus very firmly securing the standards in place. When the cultivator is in use, the tendency of the standardsis to turn in their sockets from left to right and thus loosen the nuts, and in order to guard against such action I prefer to make the threads on the standards left-hand threads and thread the nuts to correspond thereto,,whereby any tendency of the standards to turn only results in screwing up the nuts tighter.

As above described, the cross-bar is designed for a triple-plow cultivator; but under some conditions it is desirable that double plows only be employed, and for this purpose I provide a cross-bar (shown in Fig. 5) simi lar in all respects to that before described, exceptingthat it is shorter and provided with but two perforations 12 for the reception of two plow-standards.

Having described my invention, claim is 1. A metallic cross-bar for cultivators consisting of a flat bar or plate having a bolt-hole intermediate its ends for attaching the bar to thecultivator-beam, and provided with a forwardly and inwardly curved arm at its front end also having a bolt-hole for attachment to the beam, a web or rib connecting the end of the curved arm to the bar, depending flanges formed on the opposite edges of the bar and the curved arm, and a similar flange formed on the forward edge of said web or rib, and means for attaching a pluwhat I rality of plow-standards to said cross-bar, substantially as described.

2. A metallic cross-bar for cultivators consisting of a flat bar or plate having a bolt-hole intermediate its ends for attaching the bar to the cultivator-beam and provided with a forwardly and inwardly curved arm at its front end also having a bolt-hole for attachment to the beam, a web or rib connecting the end of the curved arm to the bar, depending flanges formed on the front and rear edges of the bar and the curved arm, said flanges being widest or deepest at the center of the bar and tapering toward the ends, and a depending flange formed on the forward edge of the web or rib and uniting the ends of the flanges on the curved arm to the flange on the forward edge of the bar, substantially as described.

3. A cross-bar for cultivators comprising a.

flat, flanged bar adapted to be attached to the under side of the cultivator-beam and having a plurality of tapered perforations for the reception of the ends of plow-standards, and correspondingly-tapered bosses cast integrally with said barabout the under side of said tapered perforations, in combination with plowstandards having tapered shanks fitted in said tapered perforations and bosses, and nuts screwed over the upper threaded ends of said shanks, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ALVY G. PERRY.
