CULTIVATOR.

SPECIFICATION forming partof Letters'Patent N 0. 790,300, dated May 23, 1905.

Application filed August 2, 1904. Serial No. 219,191.

To all whom it may concern:

Be it known that 1, WILLIAM F. IIARTIG, a citizen of the United States, residing atEvansville, in the county of Vanderburg and State of Indiana, have invented a new and useful Cultivator, of which the following is a specification. Y

This invention relates more particularly to improvements in that type of cultivator described and covered bya prior patent granted to me May 21, 1901, and numbered 674,408.

The object in the present case is to improve the structure of this class of devices by lightening the same in Weight, eliminating side draft and the choking of the cultivator, preventing the turning of the shovels and standards on their longitudinal axes, and at the same time permitting the adjustment of the shovels with respect to the beam, so that the cultivated path may be varied in width.

An embodiment of the invention, which is at present considered the preferable one, is illustrated in the accompanying drawings and is described in the following specification.

In said drawings, Figure 1 is a top plan View of the cultivator, part of the beam being broken away. Fig. 2 is a side elevation of the cultivator. Fig. 3 is a top plan View, on an enlarged scale, of the cross-bar. Fig. 4 is a bottom plan view of said cross-bar. Fig. 5 is a rear elevation of the same. Fig. 6 is a longitudinal sectional view therethrough, taken on the line 6 6 of Fig. 3. Fig. 7 is a detail sectional view through one of the eyes, and Fig. 8 is a detail perspective view of the upper end of one of the standards.

Similar reference-numerals indicate corresponding parts mall the figures of the draw- IDOS.

In the embodiment illustrated a beam 9 is employed of any suitable configuration, said beam having handles 10 attached to one end and, furthermore,'carrying a fender or guard 11, preferably composed ofa wire coil having an offset terminal secured to the beam.

. The cross-bar (designated as a whole by the reference-numeral 12) is in the form of an open frame comprising spaced side members 13, connected by struts 14 and 15, the struts I 15 bein located in angular relation to one end of the bar and having a web 16 disposed between the same. The side members 13 and struts 14 and 15 are reinforced on their upper sides by ribs 17 certain portions of the under side of the frame or bar being also reinforced by ribs, as 18. A beam-seat 19 eX- tends transversely of the cross-bar and diagonally thereto, said seat having its upper fiat face 20 located at an inclination to the longitudinal plane of the cross-bar; The seat 19 is connected to both the side members project beyond the opposite sides of said seat. The beam 9 rests flat against the surface 20, and thus the cross-bar will assume a position at an inclination to the horizontal, all of .which is fully set forth in the prior patent aforementioned. The beam 9 is connected to the cross bar by means of a pivot bolt 21 extending vertically therethrough and through the rear end of the seat. A holding-bolt 22, passing through the beam in advance of the pivot-bolt 21, is arranged to be passed through any of a series of openings 23, located in the front end of the seat, said series being disposed concentrically to the pivo t-b olt.

In the present embodiment the means for connecting the standards to the cross-bar are in the form of eyes 24, having standard-receiving seats and located alongside the rear side member 13 of said cross-bar, the eyes 24 being connected to the cross-bar by means of stems 25.

The eyes have. sockets 26 in their under sides, and opening from the rear side of said sockets are seats 27.- The standards (designated 28) employed in connection with this structure are similar in all respects with those shown in a design patent granted to me July 30, 1901, and numbered 34,869. Said standards have their main portions curved and provided with longitudinally-disposed ribs, one

. of said ribs, as 29, extending rearwardly. The upper portion of the standards, as 30, are vertically disposed and are adapted-to be received in the sockets 26, said upper portions having verticallyextended threaded 13, and the opposite ends of the cross-bar shanks 31, that pass through the eyes and receive holding-nuts 32. The openings through the eyes are disposed perpendicularly with respect to the upper surface 20 of the beam-seat, and surrounding said openings are flanges 33, the upper faces of which are parallel to the face 20. Thus the standards will be disposed vertically notwithstanding the inclination of the cross-bar. The ribs 29 of the standards have their upper ends disposed in the seats 27 of the eyes, and this interlocking engagement serves to prevent the rotation of said standards in said eyes.

The present structure while possessing all the advantages of that illustrated in the prior patent, No. 674,408, has others of an important nature that are absent from said other structure. In the first place it is to be noted that this cross-bar may be cast in one piece and while very light in weight is thoroughly strengthened to Withstand the strains brought against it. It will also be observed that because of the particular construction the centraleye can be placed in line with the bolts 21 and 22, while the outer eyesare located at substantially equal distances onopposite sides of the same. Thus side draft is eliminated with all itsconsequent objections. At the same time by swinging the cross-bar with respect to the beam and again fasten-- ing-itthepath-of travel of the shovels can be made wider-or narrower. Another important advantage resides in the arrangement of the standards with respect to the cross-bar. By having the eyes located in rear of the same open spaces are rovided between their upper ends which a low the escape of material caught by the standards and forced upwardly. The result is that the cultivator will not become as readily chokedand-deeper plowing can be successfully done. Furthermore, because of the interlocking connection between the u per ends of the standards and the eyes the p ows will always maintain their proper positions and will not be turned sidewlse.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to. without departing from the spirit or sacrificing any of the advantages of the invention.

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