WILLIAM S. GRAHAM, OF CANTON, ILLINOIS, ASSIGNOR TO PARLIN AND ORENDORFF COMPANY, OF CANTGN, ILLINOIS, A CORPORATION OF ILLINOIS.

RIDING-CULTIVATOR.

Specification of Letters Patent.

Patented Apr. 7, 1914.

Application filed May 28.1913, Seria1N0.770,340.

To all 10 mm if m (13 camera lie it known that I, ViLLiAM S. GRAHAM, a citizen of the United States, residing at Canton, in the county of Fulton, in the S ate of Illinois, have invented certain new and useful Improvements in Riding-Cultivators. of which the following is a spe ification, re 1'- erence being had to the accompanying draw ings.

This invention relates to riding cult ivators and it has tor one of its objects the provision otynew and improved means for angling the wheels relative to the line of draft and at the same time shifting the shovel-gang lat.- erally.

Another object, of the invention is the improvement of devices 01' this type in sundry details hereinafter pointed out.

The means by whi h I have accomplished these objects are illustrated in the drawings and are hereinafter specifically described.

That which I believe to be new is set. forth in the claims.

In the drawings, Figure 1 is a top or plan View of my improved cultivator; Fig. 2 is a side View of the machine showing one of the shovel-gangs, with one of the supporting wheels removed for clearness of illustration: Fig. 3 is a top or plan View of my improved cultivator with the shovel-gangs and the parts connected therewith removed, showing the manner of angling the wheels and shift ing the shovelarch laterally; Fig. 4 is an enlarged detail, being substantially a section on line. 4 of Fig. 1; Fig. 5 is substantially a section on line 5 of Fig. 1; and Fig. 3 is a front view of the bracket. carried by the seat supporting bars and the anti-friction roller mounted thereon.

Referring to the several figures of the drawings in which corresponding parts are indicated by the same reference characters.- 10-11 indicate axle members each comprising a horizontal portion upon which is journaled a supporting wheel 12, a vertical portion and an upper horizontal portion, said axle members being formed either separately or integrally with each other, the

*upper horizontal portions of said axle memhers l0ll being journaled in brackets 13 which are suitably conne ted to trained, H at the rear ends at said bars. The torward ends of said bars are. connected to a cross-bar 15 upon which a tongue 16 jour naled by means (i a bolt 17.

tending between the brackets 13.

it) indicates a transverse frame-bar secured to the frame-bars 14 by means of suit.- able brackets 20.

21 indicates a shovel-arch sw ingingly held in position by means of substantially verti cal bars and diagonal rearwardly-extend ing bars 213, the bars 22 being connected at their upper ends to the crossbar 19 and the bars 25;) being connected at their upper ends to the brackets 13.

2 t--25 indicate shovel-beams pivotally su 'iported at. their forward ends by means of brackets 26 upon the laterallyexteuding horizontal. ends of the shovel-arch 21. 27 indicates plows mounted in any suitable manner upon said beams 24--25. Q8 indieate toot-rests mounted upon said beams.

29 indicates a rock-shaft revolubly mounted upon the frame-bars 14-.

30 411. indicate racks fixedly secured upon the rock-shaft; 29, one ateaeh side of the machine.

32 -33 indicate levers mounted by means of brackets 34 to swing relative to the racks 3()31 respectively, each of said levers being provided with a suitable hand-latch and spring-seated detent: for holding the lever in adjusted position relative to the rack as will be readily understood. Each of said brackets 3t is provided with an arm 35 to which is pivotally connected a link 36. Said links 36 are connected at their lowerends by means of chains 37 and links 38 to the sllovrhbeanls 2--i--25, respectively, the ett'cctive length of said chains 37 being adjustable as will be readily understood by reason of its hooked connection with the link 36.

39--i0 indicate springs connected at their rear ends to the brackets 34 and at their front ends to hooks 41 which pass through suitable openings in arms 42, the forward ends of said hooks being provided with screw-threads upon which thumb-nuts 4-3 are adjustably secured. Said springs 39 tend to draw the brackets 34 forward in clockwise direction as seen in Fig. 2.

44 indicates a rack mounted upon one of the framedoars 14.

45 indicates a lever tixedly mounted upon one end of the rocteshalt 29 provided with a suitable hand-latch and detent cooperat- & ing with the rack 44 for holding the lever in 1 adjusted position relative to said rack, the

indicates a transverse frame-bar expivota y mounted relative to bell-crank levers have pivotal lever 45 being secured upon the rock-shaft 29 by means of a bracket 46.

47-48 indicate arms fixedly mounted upon the ends of the rock-shaft 29, the lower ends of said arms being connected by means of adjustable links 49 to the vertical portions of the axle members 10-11, respectivel As will be readily understood, when either lever 3233 is swung forward relative to its rack 30--31, the corresponding shovel-beam 2524 is raised throu h the medium of the links 36--38 and the chain 37, the spring 40 serving to assist in such raising o eration. It will also be understood that w en both shovel-gangs are in lowered position the lever 45 may be swung forward relative to its rack 44 turning the rock-shaft 29 and with it the brackets 34 and levers 32-33, raising the shovel-beams 24-425 in unison. By such a stroke of the lever 45 the arms 47 48 are also swung backward in clockwise direction I in Fig. 2, swingin the axle members 10-11 rearward and shi ing the wheels backward relative to the frame as is well understood in the art.

Coming now to the means for shifting the shovel-gangs laterally and for angling the wheels, 50-51 indicate bars secured on opposite sides of the tongue 16 at its rear end. 52 indicates a split collar fixedly mounted upon the upper end of the arch 21, as best shown in Fig. 4, said collar being provided at one side with a boss 53 which is journaled in a suitable opening in the rear end of the bar 51, being held in position therein by means of a suitable bolt 54 passing through said boss. It will be understood that by the means 'ust described the shovel-arch 21 is the tongue 16.

55-56 indicate brackets secured upon the under side of the cross-bar 19 by means of bolts 57. Asbest shown in Fi 5 the brackets 55-56 are in the form 0 tapered bosses, said bosses having mounted upon them bell-crank levers 58-59, res ectively, which are held in position upon t e bosses by suitable washers mounted upon the bolts 57. The forwardly-extendin arms of said fi connected to them links 60-61, respectively, the inner ends of which links are pivotally mounted upon a pin 62 passing through suitable openings in the bars 5051 as best shown in Fig. 4.

63-64 indicate seat-frame bars pivotally connected at their front ends to the outwardly-extending arms of the bell-crank le vers 58-59, respectively.

65 indicates a bracket suitably connected to said seat-frame bars 6364 near their rear ends havin revolubly mounted upon it a roller 66 which is adapted to rest upon the transverse frame-bar 18 of the machine.

768 indicate brackets secured upon the roar of the seat-frame bars 63-64, respectively, by means of a bolt 69 extending from one to the other of said bars.

-71 indicate seat bars pivotally mount ed at their forward ends upon the bolt 69 and provided at their rear ends with a seat 72. As best shown in Fig. 2 the brackets 67-68 are provided at their rear ends with arc-shaped slots 73 concentric about the bolt 69 whereby the seat-bars 70-71 are secured by means of bolts 73 in any desired adjusted position up and down relative to the seatframe bars 63-64. I

As can be understood from an inspection of Fig. 3, when it is desired to shift the shovel-gangs to one side and to angle the wheels so as to carry the machine as a whole sidewise in the same direction, this can be accomplished through the medium of the seat-bar. The act of swinging the seat-bar to the operators right, as illustrated in said figure, serves to swing both of the bell-crank levers 5859 in counterclockwise direction in Fig. 3, swinging the rear end of the tongue to the operators left and moving the shovel-arch 21 in the same direction. Upon this movement of the arch 21 the link 23 on the right-hand side of the machine serves to bring the righthand end of said shovel-arch closer to the axle member 11, and the link on the left-hand side of the machine serves to force the left-hand end of said shovelarch farther from the axle member 10. That is to say, not only is the shovel-arch 21 shifted to the left, but also the left'hand wheel is thrown slightly to the rear relative to the shovel arch and much more to the rear relative to the line of draft, serving to move the machine as a whole to the left. As the seatbar swings toward one side or the other of the machine the roller 66 rolls freely upon the upper face of the frame-bar 18 as will be readily understood. that the seat-frame bars 63-454 be formed so that their front ends stand nori'nally closer together than the distance between the rear ends of the bell-crank levers 58 59. Consequently when the seat-frame bars .63-64 are connected to said bell-crank levers it is necessary to spring the forward ends of said bars apart against the resiliency of the bars. The bars 6364 thus serve not only to support the seat and to shift the shovel-arch laterally, but also act to take up all lost motion in the connections of said bell-crank levers and of the links G0-61 with the tongue.

By reason of the construction illustrated, space is left at the center of the machine affording the operator ample opportunity to see the stalks of corn, and also making possible the use of a spreader arch of any Well-known type if desired.
