TWO-ROW LISTER.

Specification of Letters Patent.

Patented Aug'. f5, 11916.

Application filled September 16, 1914. Serial No. 862,099.

plements of the type adapted for furrow opening or for plowing, and has more particular reference to listers which employ one or more middle-bursting furrow openers.

One of the primary objects o f my invention is to provide a two-row lister of improved and simple construction which will be efficient in operation, strong and durable in construction andwhich may be manufactured at a low cost.

Another object of my invention is to provide a novelly constructed frame u pon which supporting-wheels and earth agitating-implement beams may be adjustably mounted in a simple manner.

A further object is to so mount the supporting-wheels and earth-agitating-implement beams that the supporting-wheels may be independently adjusted laterally of the frame to accommodate them to different widths of rows. n n

Referring to the drawings: Figure 1 is plan view of my improved lister. Fig. 2 is a vertical longitudinal section taken through the lister on the line 2 2 of Fig. 1, and Figs. 3 andl are enlarged detail sections taken on the lines 3 3 and -h respectively, of Fig. 1. p

Referring to the drawings it will be seen that the frameof the machine is of rectangular shape comprising front and rear cross-beams designated by the reference characters 5 and 6, respectively, arranged transversely with respect to the line of draft and fiXedly connected together by p airs of tie-bars, each pair of which comprises an inner and an outer bar designated by the reference characters 7 and `8, respectively. The cross-beams 5 and 6 which are preferably made of wood are rectangular in crosssection, and the tie-bars are formed of metallic strips having their ends bolted flat to the under side of the beams and their intermediate portions twisted to lie in a vertical plane. The tie-bars are shaped to carry the rear cross-beam higher than the forward cross-beam for the purpose of accommodating the furrow-opener beamsfand'are depressed intermediate the crossLbeams to provide mountings for supporting\vlieels, as clearly shown in Fig. 2, the purpose of this construction being hereinafter explained.

A supporting-wheel frame in the form of a casting 9 bolted liXedly to the front cross bar 5 and braced by hounds 11, extends for ward from said cross-bar and is provided at its forward end with vertical-axis journalbearings 12 in which is journaled a shaft 13,

connected to an axleltupon which supporting-wheels 15 are mounted. A collar 16 mounted upon the shaft 13 intermediate the bearing 12 is provided with a set screw by means of which the collar may be liXedly connected to the shaft to hold the shaft from axial movement. A clevis 17 iixedly connected tothe shaft 13 provides means to which either draft-bars 18 or a tongue (not shown) may be connected; and through this draft connection the front-carrying wheels may be turned upon shaft 13 to guide the implement in either direction.

A cranleaxle and a furrow-opener beam are mounted upon each side of the machine frame and, since the construction of these devices at both sides of the frame is identical, a description of the devices at one side will be suflicient for an understanding of the construction and operation of both.

A beam 19 arranged parallel with the line of draft and interposed between the tie-bars 7 and 8 at the under sides of the cross-beams, is bolted flXedly at its forward and rear ends to said cross-beams. The forward end of the beamV 19 is fastened to the cross-beam 5 by means of a pair of bolts 21 arranged on opposite sides of beam 19, and having their lower ends bent to extend through apertures in said beam and provided with -nuts 22, the bolt shanks extendingupwardly through apertures in the cross-beam and being drawn tight by nuts 23 which screw down onto a wearing plate 24 as shown in Fig. a. The rear end of the beam has bolted at each side thereof an angle plate 25 (Fig. 3) which is connected xedly with the cross-beam 6 by bolts 26 extending through said crossbeam, wearing plates 27 being interposed between the upper face of the cross-beam and the nuts of the bolts. The beam 19 is of the standard construction and has attached to its rear end a middle-bursting furrow opener 28 of any well known or preferred construction. The cross-beams 5 and 6 are provided with a plurality of laterally spaced bolt holes 30 for the reception of the bolts 21 and 2G so that the beam 19 may be adjusted laterally for different widths of rows. It is obvious that fastening means for the front and rear ends of the beams 19, other than those shown and described, might be used, and that the fastening means might be of such construction that the beams 19 could be adjusted laterally to any position intermediate the tie-bars 7 and S.

The depressed portions of the tie-bars 7 and 8 are apertured to provide bearings for a crank-axle 29, the shaft portion of which extendsbeneath the beam 19 and the crank and axle portion of which is located at the outer side of the outer tie-bar S. A supporting-wheel 31 is journaled on the outer end of the axle. The inner end of the crankaxle shaft is bent upwardly at right angles and flattened as atI 32, to accommodate a hand-lever 33 which is rigidly bolted thereto. A toothed segment-bar 34 is bolted to the tie-bar 7 adjacent to the hand-lever and the hand-lever is provided with the usual manually operable latch adapted to engage with said segment bar. It is obvious that by moving the hand-lever 33 backward and forward the crank will be swung in its mounting on the tie-bars to raise or lower the frame and the furrow openers carried thereby, the frame being fulcrumed on the front axle 14. It is also evident that with the hand-lever in a set position as shown in Fig. 2, the position of the carrying-wheel 31 will determine the working depth of the furrow opener. A seat bar 35 is mounted on the rear cross-beam intermediate the hand-levers 32 and carries a drivers seat 36.

Seeding' mechanism of any well known or preferred form may be attached to the rear ends of the beams 19, and in the present instance, I have shown merely but one seeding mechanism which is in outline designated by the reference character 37. `When the furrow-opener 28 is raised to an elevated position by operating the hand-lever so as to swing the crank-axles forwardly, the seeding mechanism will be likewise raised above the ground.

It will be manifest from the foregoing that a very simple yet strong and rigid frame is produced by the cross-beams and tie-bars arranged in the manner described.

' It is also obvious that this construction permits the mounting of adjustable supportingwheels and furrow-opening beams in a very simple manner and also permits each to be independently adjusted without interfering with or disturbing the mounting of the other.

I claim:
