Specification of Letters Patent.

Patented Aug. 1, 1905.

Application filed November 15,1904. Serial No. 232,793.

To all whom, it may concern:

Be it known that LOLIVER H. CLoYD, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvementsin Cultivators, of which the following is a specification.

This invention relates to lister-cultivators of that class embodying wheels as a support instead of runners, and has for its object to generally improve that type of lister-cultivators in which the weight of the driver and cultivating appliances and the draft of the team is utilized to assist in embedding the cultivating appliances in the soil; and my special object is to produce a machine of the type mentioned which minimizes the power to be applied on the lever in the disposal of the cultivating appliances in operative or inoperative position.

With the end in view named the invention consists in certain novel and peculiar features of cons ruction and organization, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which-- Figure 1 is an inner side view of the lefthand member of a double-row lister-cultivator embodying my invention, the seat-plank being shown in section. Fig. 2 is a top plan view of the same with the seat-plank omitted. Fig. 3 is a vertical longitudinal section on the I line III III of Fig. 2. Fig. 4 is a cross-sec tion taken through the tongue on line IV IV of Fig. 2 and showing the cross-bar, the bearing-hangers carried thereby, the front crank-shaft mounted on the hangers, and the brace-arms between the cross-bar and the ground-wheel arms. Fig. 5 is atop plan view of a modified construction of a part of the machine. Fig. 6 is a side view of the construction shown in Fig. 5, but with the lever and toothed sector omitted and with a portion of the lower part of the machine added; and Fig. 7 is a vertical section taken on the line VII VII of Fig. 6.

As the members of a double-row cultivator are duplicates, a description of one will suffice for both.

In the said drawings, 1 designates the tongue, and 2 a bracket secured upon the same near its rear end. A frame consisting of cross-bar 3, side bars 1, and forwardly-com verging bars 5 1s secured at its rear side to said bracket and at its front ends to the tongue as shown or in any other suitable or preferred manner.

6 designates bolts carried by side bars 4 of the frame, and 7 designates brackets secured to said frame by said bolts and provided with bearings 8 and 9, the former being preferably square and supporting the similar transverse cross-bar 10, which is held from longitudinal movement by spring-cotters 11.

12 designates arms clamped at the desired points on cross-bar 10, and forming a support at their lower ends for the customary groundwheels 13, said arms having lugs 14:, connected by braces 15 with a cross-bar 17, by means of bolts 16, extending through the holes 18 of bars 17, which occur in line with said arms.

19 designates a rock-shaft, rectangular in cross-section, journaled in bearings 9 of brackets 7, and adjustably secured on said rockshaft, as shown or in any other suitable or preferred manner, are the shovel-beams 20, provided at their rear ends with the adjustable brackets 21, equipped with shovels 22.

23 designates arms which are also adjustably secured as shown or in any other suitable manner, on rock- shaft 19, and 2 1 adjustable extensions for said arms, said extensions carrying adjustably, as shown or in any other suitable or preferred manner, the cultivatingdisks 25, it being understood in this connection that the special construction and arrangement of the cultivating appliances and their manner of attachment to the rock-shaft is well known in the art, and therefore not particularly described or claimed herein.

26 designates a crank-shaft journaled in bearings 27, depending from cross-bar 17, the

crank-arms 28 of said shaft projecting upwardly. Crank-arms 29 are provided with rectangular sleeves 30, snugly embracing rockshaft 19, and are clamped rigidly thereon, as at 31, and said crank-arms and crank-arms 28 are provided at their upper ends with bolts 32, pivotally engaging the side portions of the U-shaped frame 33, the front ends of said frame being pivotall y connected by forwardlyconverging links 34 to the crank-arms 35 of the rock-shaft 36, journaled in a bearing 37, secured to'the lower side of the tongue. Said rock-shaft is also provided with a crank-arm 38, pivotally connected by a link 39 to the lever a0, pivoted,as'at 4:1, to a frame 42, rigidly secured to the tongue, said frame having a sector 43, engaged by a spring-actuated catch 44 on said lever.

In the drawings, which represent one member of a two-row cultivator, the frame 42 projects upwardly and inwardly, and the lever is correspondingly inclined, so as to bring it within convenient reach of the driver. Where the member is used as a single-row cultivator, it will be preferable to dispose the lever and said frame vertically, though of course this change of position would not affect the principle of construction involved. When the member is a part of a two-row machine, the side portions of frame 33 carry arch-bars 45 to provide loops to receive the usual seatplank 46, and one end of said seat-plank is mounted on pivot-bolt 47, carried by the crossbar 48, secured at its ends to the sides of frame 33. In this connection it should be stated that the left-hand gang of atwo-row cultivator is usually that to which the plank is pivotally connected, and consequently is not ordinarily equipped with the arch-bars 45.

Under ordinary conditions the large amount of leverage given enables the driver to easily raise the cultivating appliances to inoperative position. To assist him in such operation, each gang may be provided with a pair of retractile springs 49, secured at their front ends to shaft 46 and at their rear ends to the pivots 32 of the crank-arms 29, the arrangement being such that rearward movement of frame 33 shall stretch or tension the springs in order that the latter may be in condition to assist in reelevating the cultivating appliances.

With the parts arranged as shown in the drawings it will be seen that the draft of the team tends to hold the cultivating appliances in the groundthat is to say, the draft of the team by tending to pull the tongue forwardly and from under the frame 33 actually, in 0on junction with the resistance offered by the soil to the cultivating appliances, holds said frame 33 rearward with a yielding pressure. Cooperating with this draft of the team to hold said frame and the cultivating appliances depressed is the gravitative tendency of the parts named and also the weight of the driver. When it is desired to raise the cultivating appliances, the driver throws lever 40 forward and through the medium of link 39 moves frame 33 forward, this action of the frame rocking shaft 19 and raising the cultivating appliances. After the crank-shafts connecting frame 33 with the wheeled frameviz., the tongue, the ground wheels, and the connections between the latter and the tonguehave rotated until their crank-arms pass through the center of gravity the weight of the driver, frame 33, and the cultivating appliances is shifted forward of the vertical plane of said shafts, so as to hold the cultivating appliances elevated or inoperative,in which position they are locked by the engagement of the catch 44 with sector 43. The reverse action of the lever results, of course, in swinging the rock-shafts rearward until their crankarms pass their centers of gravity, after which the weight of the driver, frame 33, and the cultivating appliances effects the depression of the latter, the draft of the team, as hereinbefore explained, and the pull upon the lever tending to embed the cultivating appliances in the soil to the required depth.

Referring to Figs. 5, 6, and 7, which illustrate a modified construction of certain parts, 33 designates the U-shaped frame, having a cross-bar 48, bolted to and upon lugs 48 of brackets 48 secured to the frame 33, and 17 designates a cross-bar similar to bar 48 and likewise secured to frame 33, but at the forward end of the latter, and said cross-bar 17 has a recess 17 in its upper side to receive the depending rib a of a bracket A, bolted to and upon the said cross-bar, a link B pivoted at its rear end for vertical movement to said bracket being pivoted at its front end for lateral movement to the lever 40, so that the operation of said lever rearward or forward shall impart corresponding movement to the U- shaped frame.

C designates a cross-bar having an arched central portion 0, fitting upon and bolted to the tongue 1, and connecting said cross-bar C to the brackets 7 depending rigidly from frame 3, are longitudinal braces D, the brackets 7 being preferably secured to the outer side of frame 3 instead of its inner side, as in the preceding figures.

Depending rigidly from the ends of the cross-bar C are brackets E, and pivotally secured thereto are cranks 28, the equivalent of the crank-arms 28 of crank-shaft 26, the upper ends of cranks 28 being pivoted to the U-shaped frame.

15 designates braces, equivalents of braces 15, to connect the lugs 14 of ground-wheel arms 12 with the cross-bar 17 It will be seen that the modified construction described is designed as a substitute for the parts 15, 16, 17, 26, 27, 34, 35, 36, 37, 38, and 39, as such modified form has been found in practice to stiffen and strengthen and generally improve the machine as well as reduce its weight and cost.

From the above description it will be apparent that I have produced a cultivator possessing the features of advantage enumerated as desirable in the statement of the object of the invention, and while I have illustrated and described its preferred embodiment it is to be understood that I reserve the right to make such changes in the form, proportion, detail construction, and arrangement of the parts as shall not be a departure from the principle of construction involved.
