SPECIFICATION forming part of Letters Patent N o. 674,408, dated May 21, 1901..

Application inea November 21,1900. serai No. 37,282. or@ man.)

To all whom, it may concern.-

Beit known that I, WILLIAM F. HARTIG, a citizen of the United States, residing at Evans ville, inthe county of Vanderburg and State of Indiana, have invented a new and useful 'Cultivaton of which the following is a specication.

My present invention relates to improvements in cultivators of that type which comprehends the employment of a diagonal crossbar or standard-carrying plate bolted to the under side of the plow-beam and serving to support a series of plow-standards and shovels.

Theinvention is directed more particularly, however, to the improvement of the cross-bar,

, whereby the latter when applied to the plowbeam will be disposed with a slight longitudinal inclination from the horizontal to locate the series of shovels in a similar inclined plane.

rlhe invention is further directed to such construction of thecross-bar as will obviate the necessity for recessing or notching the plow-beam to accommodate the upper end of the center plow-standard and the nut mounted thereon, this recessing or notching ofthe beam being usually necessary and very objectionable, as the beam is thereby materially weakened.

A still further object of the invention, subordinate, however, to those enumerated, is to stiften the cross-bar to prevent distortion of the latter without materially increasing its weight.

To the attainment of these ends the invention consists in providing the cross-bar with a beam-seat disposed at an angle to the bar and having a lateral inclination which serves to incline the bar longitudinally to permit the use of plow-standards of the same length, in elevating the beam-seat above the cross-bar to dispose the upper ends of the standards in a plane below the beam to obviate the notching of the latter, and in forming annular flanges or seats extending above and below the cross-bar concentric with the openings for the plow-standards and having their bearingfaces disposed in` planes parallel with the plane of the beam-seat to strengthen the crossbar and to facilitate the retention of the standards in perpendicular positions in a Amy invention.

manner to be made apparent, the cross-bar being further strengthened byasurrounding flange extending both above and below the same. i

The invention resides in certain other features of construction and arrangement, all as will hereinafter be fully described, illustrated in the accompanying drawings, and defined in the appended claims.

In said drawings, Figure 1 is a plan view of a cultivator constructed in accordance with Fig. 2 is a side elevation thereof. Fig. 3 is a plan View of the crossbar det-ached. Fig. 4 is an end elevation thereof. Fig. 5 is a longitudinal section on the line 5 5 of Fig. 3. Fig. 6 isa transverse section onthe line 6 6 of Fig. 3, and Fig. 7 is a bottom plan view of the cross-bar.

Referring to the numerals employed to designate corresponding parts throughout the views, l indicates a plow-beam of usual coustruction, 2 the handles, and 3 the support, bar, or cross-bar disposed below the beam aty an angle to the line of draft and employed for the attachmentof any desired number (but preferably three) of plow-standards 4, carry-v ing shovel-plows or other forms ofblades 5.. The cross-bar 3 is a comparatively light metal casting comprising the cross-bar proper in the form of an elongated plate having a laterally-curved front end 6, connected at its'extremity to the contiguous side of the crossbar by a narrow web 7. The extremity of the curved end 6 is given a decided rise to locate it and the web 7 in a plane above the bar to form an elevated or offset beam-seat 8, disposed diagonally from the front edge of the end 6 to the opposite side of the bar 3 at a considerable distance from the front end of the latter. One side wall 9 of this elevation or offset is given a lateral inclination increasing in degree from the rear end of the beamseat to its outer extremity. The bar 3, the curved front arm thereof, and the web 7 are provided with a continuous depending ange l0, which is extended slightly above the up- ICO when the inclined face of the seat is disposed directly against the horizontal under side of the plow-beam. Therefore, if a series of plowstandards of identical length are pendent from the bar the plows will be disposed in horizontally-inclined series, which is a necessary arrangement in cultivators of this type and is ordinarily obtained by employing plowstandards of different lengths or by making special arrangement for endwise adjustment of the standards to secure proper relative 'penetrations of the plows or shovels.

The elevated beam-seat is preferably cast hollow, as shown, and adjacent to its opposite ends the top wall thereof is provided with bolt- holes 11 and 12 for the reception of securing-bolts 13, passed through the plowbeam, the hole l2 being disposed in the plane of the longitudinal center of the bar 3.

We have now seen that by providing an elevated beam-seat which is both longitudinally and transversely inclined with respect to the crossbar the latter when attached to the plow-beam will be given such longitudinal inclination as is necessary7 to secure the desired relation of the shovels or plows. It will be seen, however, that the attainment of this result is accompanied by slight transverse inclination of the cross-bar.4 Provision must therefore be made for permitting the plowstandards to assume true perpendicular positions, as shown in Fig. 2. This is accomplished by providing openings 14, 15, and 16 at the center of the bar and at the front and rear ends thereof, the opening 14 being disposed closely adjacent to the oiset beamseat, which latter is formed with a concavity 17, concentric therewith. 'Fliese openings are designed for the reception of the threaded shanks 1S of the standards fi, and their axes are perpendicular to the plane of the beam-seat or bearing-face--that is to say,the axes of these openings are not perpendicular to the plane of the cross bar or plate, but are in slight angular relation thereto in order that the standards may assume perpendicular positions with respect to the horizontal under face of the plowbeam, and therefore positions perpendicular to the ground. This being true, it follows that provision must be made for properly abutting or seating the bearing-shoulders 19 of the standards, disposed below the bar, and the securing-nuts 20, screwed upon the shanks 18 above the bar. This I accomplish by casting upon the upper and under faces of the bar 3 a series of annular projections, flanges, or seats 21 and 22, surrounding the openings and having their upper or under faces, as the case may be, disposed in planes parallel with the plane of the beam-seat, so that the shoulders 19 may bear squarely against the seats 22, while the seats 21 facilitate in like manner the even rigid abutment of the nuts 2O when screwed to place to secure the plow-standards in rigid relation With the bar.

When the bar is secured to the plow-beam, as in use, it will be disposed in diagonal relation thereto, as shown" and will be longitudinally inclined from the horizontal to dispose the shovels in a horizontally-inclined series; but the bar is disposed asufiicient distance below the plow-beam to permit the nut 2O of the intermediate standard to be disposed below the beam instead of being located within a cnt-out portion thereof, as in cultivators of the usual construction.

It will therefore appear that l have produced a cross-bar for cultivators embodying a construction best calculated to effect the accomplishment of the Various objects sought to be attained; but while the present construction illustrated and described is believed at this time lo be the preferable embodiment of the invention l do not wish to limit myself to the details of construction and contour enumerated, but reserve the right to effeet such changes, modifications, and variations as may be clearly embraced within the scope of the protection prayed.
