LIVINGSTON OASE, OF BONDURANT, IOWA, ASSIGNOR OF ONE-HALF TO H. E. TALBOT, OF DES MOINES, IOVA.
DISK HARROW.
Specification of Letters Patent.
Patented Oct. 17, 1905.
Application iiled October 8, 1903. Serial No. 176,210.
To all whom, t may con/cern:
Be it known that I, LIVINGSTON OASE, acitizen of the United States, residing at Bondurant, in the county of Polk and State of Iowa, have invented certain new and useful Improvements in Disk Harrows, of which the following is a specification.
The objects of my invention are to provide a disk harrow of simple, durable, and inexpensive construction, in which the two framesections may freely move up and down relative to each other, so that they will readily conform to the surface over which they are traveling.
A further object is to provide a harrow of this class having two sections, in which the sections may stand in line with each other, and yet the disks may be quickly and easily set at any angle desired relative to the line of advance of the machine, so that the said disks may cut into the earths surface and throw the earth as little or as Vfar as desired.
My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the'accompanying drawings, in which Figure 1 shows a top or plan View of the complete machine, the drivers or operators -seat being removed. Fig. 2 shows a rear elevation of the complete machine. Fig. 3 shows a vertical sectional view on the line 4 4 of Fig. 1, the frame-supporting arms being omitted. Fig. 4 shows an end elevation of one of the disk-supporting frame-sections, a part of one of the vertical shafts being shown in position; and Fig. 5 shows a top or plan view of one of the armsi'or supporting the harrowsections to illustrate the slots therein.
Referring to the accompanying drawings, I have used the reference-numeral 10 to indicate a tongue, and 11 a cross-piece fixed to the tongue and rigidly supported in position bythe braces 12. On the end portions of the cross-piece 11 are two arms 13 on each end, projected rearwardly and provided with the transverse slots 14, for purposes hereinafter made clear, one arm on each end being on top of the cross-piece 11 and the other one below. Near the central portion of the cross-piece 11 are two arms 15, hinged to the cross-piece at 16 and projected rearwardly, so that their rear ends may move up and down. The rear end portions of these arms 15 are inclined straight upwardly for purposes hereinafter made clear.
On each side of the machine-frame is a harrow-section. Thesesections are both alike, and hence but one will be hereinafter described.
The reference numeral 17 indicates two parallel bars, which form the body of the barrow-section frame. These bars are held apart and adapted to support the upright shafts of the disks by means of the metal braces 18, each of which has a top and bottom and two ends. with openings in the top and bottom to receive the upright shafts. These pieces are placed between the bars 17 and are held in place by bolts 19, passed through their end portions and throughV the bars 17. On the interior of each of the parts 18 is a sleeve 2() of such length that its ends engage thetop and bottom of the part 18, and a set-screw 21 is seated in each sleeve.
The reference-numeral 22 indicates a tubular shaft passed through the openings in the top and bottom of the part 18 and also through the sleeve 20, and it is firmly held against upand-down movement by means of the setscrew 21. The upper end of this shaft projects beyond the part 18, and fixed to each of the shafts 22 is a rearwardly-projecting arm 23, fixed to the shaft 22 by the set-screw 24. The barrow-frame sections thus formed are supported in the arms 13 as follows:
The reference-numeral 25 indicatesametal plate having a fiat top provided with a projection 25EL to enter the slot 14 in the plate 13 and also having two downwardly-projecting ribs 26 and 27 parallel with each other at its front edge and two similar ribs at its rear edge. rIhese ribs are designed to admit the frame bars 17 between them. -A similar plate is provided for the under surface of the bars 17, and these plates are passed between the rear ends of the arms 13.
The reference-numeral 28 indicates a bolt passed through the slots 14 in the arms 13 and also through the washers 29, thus connecting said parts and permitting the frame 17 to tilt vertically to a limited extent, because the said projection 25 on the plate 25 and bolt 28 pass through the slots 14 in said arms 13. The inner ends of the harrow-'frame members are pivotally connected with each other by the IOO pin to be capable of swinging vertically, and each of the arms 15 is connected withthe adjacent harrow-frame member by having its upturned rear end passed through ablock 31, fixed between the frame members 17 by the screws 32, and a pin 33 is passed through the upper end of each of the arms 15, thus permitting the frame-sections to move vertically a limited distance, because the screws 32 permit the blocks 31 to tilt slightly in the frames.
I have provided means whereby all of the shafts 22 in each frame-section may be turned in unison, as follows: The reference-numeral 341 indicates a bar pivotally connected by the bolts 35 with the rear ends of the arms 23. The reference-numeral 36 indicates a block fixed to each harrow-section, and pivoted to said block is a lever 37. This lever is also pivoted to the bar 34 and provided with a spring-actuated pawl 38, designed toengage a sector 39 on the harrow-section frame, `so that by operating the lever 37 all of the shafts 22 may be rocked in the same direction. Each of the shafts 22 is provided with a disk 40 of ordinary construction.
In practical use the harrow is advanced over the ground by draft-animals hitched to the tongue in the ordinary way. Thelevers 37 are set to position, so that'thedisksineline from a 'fore-and-aft lineto the angle, which is found the most desirable for the work which the machine is intended to do. If the harrow is running over uneven ground, the two sections may tilt a short distance relative to each other, so that each section will lie flat on the earths surface over which it is passing.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the vUnited States therefor, is-
An improved disk harrow, comprising' a machine-frame, two independent harrow-section frames in line with each other, means for supporting vsaid frames upon the machineframe and for permittingsaid frames to tilt relative to l,the machine-frame, means for pivotally connecting the said harrow section frames at their inner ends, a number of verticallyarranged rotatable shafts in each frame, a disk for eachshaft` an arm fixed to the upper end of .eachshaft, a bar pivotally connected .toiall of the arms of each section and a lever fulcrumed to each frame-section and pivoted vto each bar.
