SPECIFICATION forming part of Letters Patent No. 358,557, dated March l, 1887.
Application filed Api il Q2, 1856.
.To @ZZ whom, it may concer/1,:
Be it known that I, WILLIAM A. Known- '.roN, a citizen of the United States, residing in the city of Rockford, in the county of Vinnebago and State of Illinois, have invented new and useful Improvements in Cultivators, of which the following is a specification.
This invention relates to a class of cultivators known as the straddle-row cultivator.
The object of this invention is to regulate the running-depth of the shovels and hold them 'to their adjusted running-depth, to assist in lifting the shovel-beams and the shovels thereto attached, and to support them in their ele` vated position. To accomplish these objects and other features, all of which will be hereinafter more fully described, I have designed and constructed the apparatus represented in the accompanying drawings, in which- Figure 1 is a plan view of portions of a cultivator embodying my invention. Fig. 2 is a side elevation showing my improvements. Fig. 3 is a transverse verti cal section on dotted line e on Fig. 2, and Fig. 4 is a transverse vertical section on dotted line Z) on Fig. 1.
The several parts represented in the figures of the drawings, consisting of the wheels 1, arching or crank-formed axle-tree 2, tonguebeams 3, shovel-beams 4L, shovels 5, and handles 6, are substantially such as heretofore employed in like machines.
The shovel-beams are joined and supported in their relative position near their forward ends by a tubular stretcher, 7, and a screwbolt passed through the beams and through the tubular stretcher to clamp and hold the beams in position against the ends of the stretcher. A tubular stretcher, S, is placed between the rear portion of the beams, and a screw-bolt is passed thronghthe handle 6, through the beams 4, and tubular stretcher S and serves to clamp and hold the parts in their relative position. rlhe stretcher 8 is provided with a spring-supporting arm, 9, extending from its central position 'forward in a horizontal plane between the shovel-beams,and is provided with a series of transverse horizontal holes, for a purpose hereinafter to appear. The stretcher 8 is also formed with depending end arms with lugs to embrace the under edge of the beams, to prevent the stretcher turning on its bolt-support.
Serial No. 199,772. (No model.)
An open-sided joint-clip, 10, embraces the horizontal end portions of t-he axle-tree, inside ofthe wheels, and this clip is provided centrally with rearward-projecti'ng ears 11, formed on their opposite outsides with semispherical or conic-recessed bearings.
An intermediate joint-yoke, l2, to connect the shovel-beams with the axle-tree, is provided with forward-projec'ting ears 13, to overspan the rearward-projectine. ears of the clip, and are bored to receive the tubular journals 14, employed to produce a hinge-connection of the yoke with the clip. The tubular journals have their bearing ends formed to engage the recessed bearings in the ears of the j oint-clip, and a screw'bolt, 15, passed through the axial center of the tubular bearings, serves to tix the clip to the axle-tree in a manner to permit its adjustment lengthwise thereon to vary the relative position of shovel-gangs and permit a lat-eral swinging movement of the yoke on its tubular jouinalsupports. The yoke is provided with rearward-projecting ears 16, which receive the forward ends of the shovelbeams, and a joint-bolt, 17, passed through the parts, serves to connect the beams with the yoke in a free manner, to permita vertical movement of the shovel ends of the beams. rIhe yoke is also provided with a horizontal arm, 18, projecting rearward, and a vertical arm, 19, rising, from its rear end centrally between the shovel-beams.
The vertical. arm 19 of the intermediate joint-yoke is provided with a series of transverse holes. An endWise-compression spring, 20, in this instance produced from plate material in S form, is connected at its forward end to the vertical arm 1.9 of the intermediate joint-yoke, and at its rear end to the horizontal spring-supporting arm 9 of the tubular stretcher 8. The spring 20 in its connection with the horizontal spring-supporting arm, by means of the series of holes formed therein, is made adjustable lengthwise thereon to vary its spring-force, and in its connection with the vertical arm of the joint-yoke, by means of the series of holes formed therein, is made ver tically adjustable, to vary its downward aetion to regulate the running depth of the shovels or its upward action to vary its lifting and holding force on the shovel-beams. This action will be readily understood by an in- IOO spection of Fig. 2 of the drawings, in which the shovel-beam in its solid-line position is below the connection of the spring with the vertical arm of the jointyoke, and consequently the spring action tends to depress the shovel ends of the beams and cause the shovels to run at a greater depth, and'when the beams are raised abovethe connection of the spring with the vertical arm its spring action will tend to lift the shovel ends of the beam to support them in their elevated position, as represented in the dotted lines.
In the drawings I have represented but portions of one side of a straddle-row cultivator, and the portions necessary to a complete machine, not duplicates of the parts shown and herein described, may be any of the varieties of such parts known and used for like purposes, capable of use in connection with my improvements.
I claim as my inventionl. The combination, with the axle-tree, of the joint-clip embracing the same and provided with rearwardly-extending and perforated ends, recessed on their upper and lower sides, ayoke having forwardly-extending perforated ears, tubular journals seated in said ears and having their inner' ends bearing in the recessed parts of the clip ends, and a bolt pivotally connecting said clip ends and yokeears to rigidly clamp the joint-clip against oscillation on the axle, substantiallyr as set forth.
2. The combination,with thejoint-yoke and with the shovel-beams pivoted thereto, of a spring connecting `the yoke and shovel-beams,
said spring connected at its forward end to the yoke rearward of its connections with the shovel-beams and at its rear end to the shovelbeams rearward of its connection with the yoke,
substantially as and for the purpose set forth.
3. The combination, with the joint-yoke and with the shovel-beams hingejointed to the yoke, of a spring connected with the yoke and the shovel-beams, said spring made vertically adjustable in its connection with the yoke, substantially as and for the purpose set forth.
4. The combination, with the joint-yoke and with the shovel-beams hinge-jointed to the yoke, of a spring connected with the yoke and with the shovel-beams, said spring made adjustable in its connection with the beams lengthwise thereof, substantially as and for the purpose set forth.
5. The combination, with the shovel-beams, of a joint-yoke hinge-jointed to the beams, said yoke provided with a horizontal arm projecting rearward, and a vertical arm rising from its rear end, said vertical arm provided with a series of transverse holes, substantially as and for the purpose set forth.
6. Thecombination,withthehorizontalarm,
