My present inventionhas referencel to a' new and novel plow construction@ which is primarily in the nature ofi aV lister or rid# ing.` middle breaker and among the objects 5. of the invention is the provision ofy aj plow construction in which the bottom orshovel may be tilted or oanted upon its standard support to engage in different depths of soil, onein which the plow lift includesa- 10 rack surface on the standard which is engaged` by a lever operated toothed wheel, so that the plow may be easily and quickly adjusted with respect to the frame thereof andpositivelyheld when adjusted; one in which a-hitch shift of` a new and novel arrangementis provided, the same including means for imparting an angular movement to one of the wheels of the machine and to simultaneously impart a similar movement'to the clevisl to arrange the same in the same direction as thatof the wheel, sothat the plow willbe positively directed atvarying desired angles or when the same is to make its return movement' over the field, and further one in whichthe operating means for all of the parts are inclose proximity tothe drivers seat, which latter is also'adjustable on theV beam-of the plow.

To theattainment of the foregoing the invention consists/in the improvement hereinafter described and'denitely claimed.

In the drawings:

Figure 2 is a side elevation thereof with parts insection. Y

Figure Bis a substantially vertical longi# tudinal sectional view through the improve; ment.

Figure 4 is a rear elevation thereof.

Preferably my improved plow constructionsisr entirely constructed oflmetal which enhances` the sturdiness and stability thereofl and the ground or traction wheels of the improvement are indicated by the numeral 1.

Each of the wheels 1 isjournaled on the spindle end of an axle. From its spindle each ofthe axles `is extended downwardly, as at 2,'and from thence bentinwardly and extended upwardly, as at 3. Thusy the lower 1929il Serial No; 353,457.

portion of each of the axles is Ueshaped or` cranked. f

The plow beam is indicated by the numeral 4. The beam passes. between the' spacedlower plates 5 of the standard. The upper portion-'of the'standardis xedly securedl between the plates 5 and is for distinc-l tionindicated by the numeral 6. This portion of the standard isy provided withteeth 7, and, therefore, is in the natureof a rack. T-he beam is fixed between the plates 5 of the standard, and the beam hassecured to the sides thereof rearwardly directed plates 8 that have their ends formedwith' eyes 9 thatprovide guides throughV whichthe vert-icalv inner portions of the axles pass.

There is arranged between the spaced.- plates 5' or what may be termed the bifurcated lower portion of the standard a curved tongue 10 which is pivotally secured Vtoy the standard, as at 11 and which has' an angle rearwardly extending lower portion in thel nature of a runner 12. The tongue, at its juncture with the runner, is formed with an extension that has its outer end divided to provide the same with what I will term angularly directed ears 13 and` these ears are loosely pivoted, as at 14, to the sides or molds of the plow bottom or shovel 15.

The mold sides of the shovel are formed with ring extensions 16 and a tongue 17 which is arrangedV therebetween. There is y passedthroughvthis tongue and the tongue or the angle extension 10 ofthe runner' 12 theshank' of aheaded bolt 18. There are washers-between the head of the bolt `18 and the rear edger of the rounded and .bifurcated end- 5 ofthe standard 6, one of said washers, indicated for distinction by the numeral 19,-'contactingi with the said rear edge of they standard. Arranged aroundl the shank ofthe bolt and having one of its ends contactingwith the washers 19 and its other end contacting with an outer washer 20 there is a coil spring 21. There is screwed on the end of the bolt 18 a nut 22 which engages with the washer 20 and' thereby regulates thev tensionof the spring 21;

The upper endof the tongue extension 10 of the runner 12is rounded and formed with teeth 23 which are in mesh with the teeth of a wheel 24 whose shaft 25 is journaled in suitable bearing openings in the plates 5 of the standard. The shaft 25 has one of its ends offset and formed with an extension in the nature of a lever 26, the said lever having fixed thereon a transverse plate 27 that provides a gripping surface for the foot of the operator of the plow.

The rear end of the beam 4 is slightly rounded downwardly, and has secured therearound a substantially U-shaped clip 28, the securing means for the clip being in the nature of a removable element such as a bolt engaged by a nut. The clip receives therein the lower end of a curved spring support 29 for the drivers seat 30. Arranged along the sides of the beam 4, inward of the clip 28, there are plates 31, and passing through and connecting the ends of these plates there are adjustable means, broadly indicated by the numerals 32, the

said means being preferably in the natureof bolts which are engaged by nuts. By this arrangement it will be noted that the supporting spring 29 for the seat 30 may be adjusted to bring the seat toward or away from the beam and likewise by this means it will be noted that the seat 30 may be adjusted longitudinally on the beam.

As far as the description has progressed it will be obvious that a pressure of the foot of the rider upon the lever 26 will cause the turning of the toothed wheel 24 and the said toothed wheel engaging with the teeth or rack on the end of the tongue or extension of the runner 12 will tilt or cant the plow bottom or shovel 15 upon the pivot 11 so that the point of the plow may be raised to a determined degree, a release of pressure upon the lever permitting the spring 21 to return the plow bottom or shovel to its initial position.

The vertical members or extensions 3 of the axles are each guided through a pair of spaced eyes or bearings 33 formed on the ends of plates 34 provided on the ends of a bar 35. The plates 34 and their bearing portions 33 may be in the nature of substantially U-shaped brackets which are bolted or otherwise xed to the bar 35 but the said elements 34 and 33 may be integrally formed with the bar. Thel bar and the ends thereof are really in the nature of a frame, and the central portion of the said frame is integrally formed with an upstanding member 36 that is provided with spaced outwardly extending arms 37. Thus the projection 36 is in the nature of a bifurcated member and receives therethrough and provides a guide for the non-toothed face and sides of the rack extension of the standard. There is journaled between the side members 37 of the projection 36 a shaft 38 which has fixed thereon a toothed wheel 39 that is in mesh with the teeth of the rack 7 One end of the shaft 38 may be bent or may have secured thereto a rearwardly extending lever 40. The lever, however, is preferably removably secured to the shaft, and the connection therebetween is rather loose being suiiicient to permit a slight lateral movement of the lever in order to bring the same into or out of notches 41 provided in an arched rack 42 which is fixed on one of the parts 38 of the element 36. The lever 40 has an offset end 43 providing a grip for the hand of the occupant of the seat 30 and by this arrangement it will be seen that a swinging of the lever will cause the turning of the toothed wheel 39 which engages with the rack 7 and consequently a vertical adjustment of the standard and the plow bottom carried thereby with respect to the beam 4.

In this manner it will be seen that the plow bottom or shovel may be properly regulated with respect to the depth of the furrow to be made thereby and also by this arrangement it will be seen that the shovel may be raised above the ground surface when the plow travels over a field before being brought to operative position.

ITo more effectively reinforce the standard with respect to the beam there is pivotally connected to these elements angle braces 44.

The extension 3 of one of the axles is fixed in its bearings but the extension 3 of the second axle may be turned in its bearings 33. This last mentioned extension 3 has fixed thereon a sleeve 45 that rests on the upper face of the lower bearing 33, the upper face of the said sleeve being roughened for coengagement with the roughened under face on one end of a lever 46. Surrounding the extension 3 and exerting a pressure between the upper bearing 33 and the said end of the lever there is a coil spring 46. Obviously the lever may be otherwise connected with the sleeve 45. The lever hasl a widened or laterally extendin portion 47 provided with an arcuate slot 48 through which the plate 34 passes. The upper end of the lever is formed with an angle extension in the nature of a hand grip 49. The under face ofthe lever may be provided with a' tooth or the said lever may be received in notches 50 provided in an arched rack 5l that is fixed to the body member 35 of the frame. The inner end of thelever 46, at the portion thereof through which the s lift extension 3 passes has an extension 5 2 which is bent upwardly and from thence inwardly forming this end of the lever with what may be termed an arm.

There is pivotally secured to the outer end of the arm 52 the bifurcated end of a link 53. The link is arranged angularly over the beam 4, and the second or free end of the link is pivotally connected to one end of a centrally pivoted rocker member or arm 54. The rocker arm has its pivot 55 received in an upstanding lug 56 on the beam 4. The second end of the rocker arm 54 has pivotally connected thereto one of the bifurcated ends of another link 57. This link is forwardly directed and is normally arranged in a plane with the beam. The second bifurcated end of the link 57 is pivotally secured to the inner and angle end 58 of a clevis 59. The clevis is pivotally secured, as at 60, to the outer end of the beam l or rather to a bearing member which is fixed on the said outer end of the beam. By this arrangement it' will be noted that when the lever 46 is shifted one of the ground wheels l will be turned angularly with respect to the frame of the device and by virtue of such turning the rocker arm 54 will be swung by the link 58, and consequently the link 57 will swing the clevis 59 in the same direction and to the same angle as that assumed by the ground wheel l. The lever 46 engaging in one of the notches 50 in the rack 5l will hold the said wheel and the clevis at desired angle positions with respect to the remainder of the construction, and by this simple means it will be seen that I have provided a hitch shift which not only changes the line of draft of the plow but incident to the turning of the ground wheel will automatically cause the draft animals or the tractor by which the plow is drawn to assume a proper position for pulling the said plow.

It is believed that the construction7 operation and advantages of my improvement will be understood and appreciated by those skilled in the art to which the invention relates when the foregoing has been carefully read in connection with the accompanying drawings but obviously I do not wish to be restricted to the precise details herein set forth and, therefore, hold myself entitled to make such changes therefrom as fairly fall within the scope of what I claim.

That I claim is An agricultural implement comprising a wheel supported frame, a beam connected with the frame, a standard connected with the beam, said standard having a bifurcated lower part, a plow having a rearward eX- tension which passes between the lower end of the bifurcated portion, means for pivoting the extension in said bifurcated part, a bolt passing through an upper part of the plow and through the bifurcated portion, a spring on the rear of the bolt and bearing against the rear edge of the beam and the nut on the bolt, said extension having an upwardly extending part arranged between the members of the bifurcated portion of the standard, with teeth on its upper end, a pinion carried by the standard and engag- Awardly or downwardly when the foot engaging member is actuated.

In testimony whereof I aix my signature. 4f
