SAMUEL L. ALLEN, 0F MOORESTOWN, NEW JERSEY.

CULTIVATOR.

Speciiicaton of Letters Patent.

Application filed January 9, 1908. Serial No. 409,935.

To all whom it may concern.'

Be it known that I, SAMUEL L. ALLEN, a citizen of the United States, and a resident of Moorestown, county of Burlington, State of New Jersey, have invented certain new and useful Improvements in Cultivators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in cultivators and more particularly to riding cultivators which are adapted to work a number of rows at a time.

The main objects of my invention are to increase the eiiiciency of a cultivator of this class and to lessen the laborl required in its operation.

More specifically stated the main objects of my invention are to provide in a cultiva tor. improved steering mechanism; an improved means for adjusting and clamping the cultivator blades in position; improved means for'balancing the tongue of the cultivatorgand for raising the cultivator blades; and other improvements, all of which will be more fully set forth in the following description and claims.

In the accompanying drawings, Figure 1 is a side elevation of a cultivator constructed in accordance with this invention; Fig. 2 a top plan view of the same; Fig. 3 a fragmentary perspective View of one of the wheels and its support, and part of the steering gear; Fig. 4 a fragmentary side elevation of part of the steering gear, showing the steering means and the foot rest; Fig. 5 a plan view of the portion shown in Fig. 4; Fig. 6 a fragmentary side elevation showing the inner side of the tongue and its supporting means; Fig. 7 a fragmentary rear elevation of the tool bars and tools carried thereby; Fig. 8 a top plan view of one of the tool clamps in position upon the tool bar; Figs. 9, 10 and 11 are transverse sections on the lines 9 4), 10-10 and 11-11 respectively of Fig. 7

Referring to the drawings, one embodiment of this invention comprises a substan-` tially rectangular main supporting frame 1 extending substantially the full width of the machine and having a transverse tubu lar member 2 forming the rear side thereof and projecting over the supporting wheels 3 which are carried thereby.

The side wheels 3 are supported upon L- shaped axles 4 which are pivotally mounted in the vertical standards 5. The upper ends of the standards 5 form split sleeves G which are slidably mounted upon the said trans-` verse tubular member 2 of the main supporting frame and are held in any desired position thereon by means of bolts 7 passing through the standards to bind the parts of the sleeves together. Each axle 4 has a bracket 8 rigidly secured thereto and carrying a crank arm 9 and also a bar 10 extending over the edge of the wheel to :orm a scraper. The said crank arms of the wheel axles' are pivot-ally connected together by means of a pair of links 11, which are provided at their ends with a series of holes l2 spaced longitudinally of the links and adapted to receive the pivot bolts 13 Whereby the ends of the crank arms may be connected at various points to the links.

Each wheel standard is provided at its lower'end with abrace 14, connected at one end to the standard by means of the Jolt 15 and at its other end to the forward transverse member of the main supportingframe by means of the bolt 16, the said member of the frame being provided with holes 17 spaced longitudinally of the member Whereby the'outer end of the said brace may be connected at various points to the fr ame.

The adjustment of the wheels transversely of the machine to correspond to various widths between rows is accomplished by disconnecting lthe free ends of tte axle crank arms from their links, and thc outer ends of the standard braces from the frame, and loosening and sliding the wheel standards upon their tubular support to bring the wheels into the desired ositions, after which the standards are tig tened and the crank arms and braces are correspondingly connected to the links and frame respectively.

The draft member of the cultivatoir is, in

this instance, a tongue 18, which is pvoted g at its inner end, by means of a bolt 19 between a pair of braces 20, the ends of the braces being flanged and rigidly secured to the front and rear transverse members of the main supporting frame 1 of themachine. The tongue is also provided with oblique braces 21, the outer ends of-'which are rigidly secured to the tongue by means f the bolts 22, and the inner ends of which are pivotally secured by means of the bolts 23 between pairs of braces 24, the outer ends Patented Nov. 14, 1911.

of the braces bein main supporting rame by means of the bolts 25, and the inner ends of the braces being secured to the tubular transverse member of the main frame by means of the bolts 26.

The main rectangular supporting frame is provided with a rearwardly extendlng frame rigid therewith and comprising the rearwardly extending side bars 27, the forward ends of which are secured between the said pairs of braces 24 respectively, of the main frame, by means of bolts 28, These side bars 27 extend in parallel directions from their forward ends rearwardly and upwardly, resting against the under surface of the transverse tubularmember 2 to stiifen the frame structure, and at points a short distance behind and above the transverse members are connected to the tubular member 2 of the main frame by the segmental brackets as will be hereinafter described, and are turned downwardly and then inwardly converging to embrace at their rear ends a bearing 29 for the swinging yoke 30 carrying the follower wheel 31.

The steering of the machine is effected by means of a steering-lever or bar 32 which is provided at its ends with foot rests 33 which is mounted upon a pivot 34 carried between the yoke formed by the bars 35 and 36 and which are rigidly secured together by -a bolt 37. The bar 35 is turned downwardly at its ends and rigidly secured to the

crossbraces

38 and 39, the lends of which are rigidly secured to the side bars 27 ofthe supporting frame. The steering lever is provided with a forwardly extending steering arm 40 which is rigidly connected to the said steering lever at one end, and is held in position with respect to said steering lever by means of the braces 41, and the forward end of this arm is pivotally connected between the said links 1 1 which connect the free ends .of the said axle crank arms. An aperture 42 is provided, through links 11 and the ception of a pin 43 whereby the steering mechanism may be held in locked position.

A seat 44 is supported on a spring 45 which is secured to a brace 46, rigid with the frame of the machine, and also to the said bar 35 which supports the steering lever. The portion of the bar 35 supporting the steering lever is inclined to the frame of the machine and is substantially in a plane intersecting t-he seat whereby the steerin lever is caused to swing substantially 1n a plane with the seat, making the steering lever easy to operate from the seat as the force applied from the seat is in the direction of the motion of the lever and not oblique to the plane of the movement of the lever as in other structures.

.The tool carrying frame, or member, comprises three

parallel tool bars

47, 48 and 49,

rigidly secured to the bar 35, for the ref,

of channel iron, arranged in a vertical series extending transversely of the machine, supported in vertical slotted plates 50. The cent-ral bar 48 is fixed in position with respect to the said plates by means of pins 51, and is provided upon one side thereof, with a curved extension 52 forming a segmental rack 53. Pivoted to the lower portion of the extension 52, is the hand lever 54 carr ing a spring pressed pawl 55, engaging sald rack 53, and actuated by a lhandle 56. The top and

bottom tool bars

47 and 49 are connected to the lever 54 by arms 57 secured in the channels of the bars and having curved outer ends connected to 58 whereby, when the hand lever 54 is swung upon its pivot, the

tool bars

47 and 49 are reciprocated transversely of the machine.

Improved tool clamps 59 are provided for the purpose of rigidly securing the Shanks 60 of the tools 61 upon the said tool bars. Each of these clamps is constructed as shown in Figs, 8 and 9, and comprises a yoke 62 having a rectangular inner portion adapted to lit over the tool bar and having outwardly diverging ends 63 provided with slots 64. A key 65 provided with a recess 66 in the outer edge thereof having inwardly converging sides 67 spaced t0 engage against the outer surfaces of the yoke, rests in the slots and between the outer ends of the yoke and the tool shank 60. The inner end of the yoke is provided with a set screw 68 adapted to engage against one side of the tool bar, and to draw the yoke inwardly with respect to its wedge, whereby the sides of t-he yoke are forced against the sides of the tool bar by the converging sides of the recess in the wedge and the tool shank is held rigidly in place.

The tool frame is pivotally secured to the main supporting frame of the machine by means of the arms 69, the rear ends of which are rigidly secured to the supporting plates 50 byrivets 70, and the forward ends of which are pivoted between the side members of the mam frame 1 and the brackets 71, rigid with the same upon the bolts 72. For swinging the tool frame, a air of hand levers, oractuating members, 3, are provided, arranged one upon each side of the seat and substantially in vertical alinement with'the forward ends of the side bars 27 of the rear portion of the frame of the cultivator. The forward ends o-f t-hese levers 73 are pivoted by means of bolts 74 upon bracket-s 75, which are rigidly secured to the tubular member 2 of the main frame b the bolts 26 which pass through open en ed slots 76 in the cylindrical portions of the brackets, and as heretofore described, also tubular member andthe inner ends of the frame braces 24 to which the tongue and the side bars 27 of the rear portion of the frame are connected. The brackets` 75 are also pass through the rigidly secured to the outer sides of the said side bars 27 of the frame by means of bolts 77 which pass through the outer lower ends of the brackets-and the portions of the side bars at the vertex of the angle between the upwardly and the downwardly extending portions thereof. Extending downwardly from the brackets, are arms 78 integral therewith, which bear against the 0 outer side surfaces of the downwardly extendin forward portions of the said side bars 2 of the frame to further brace the frame and bracket. The curved portion of the bracket is provided with slots 79, and .5 the levers 73 are providedwith the usual spring engaged pawl 80 engaging said slots. The hand levers 73 are each separately connected to the tool frame by means of a well known form of yielding telescoping connection 80, and the vertical position and movement of the tool frames is thus controlled from the seat of the cultivator by means of the hand levers 73 which may be operated either separately, or in unison. Furthermore, the ton e 18 of the cultivator, is `yieldingly supportedby the hand levers, by means o a spiral spring 81, which is secured at one end to the inner end of the tongue and at its opposite end to a slightly flexlble cross bar 82, the endsl of which are rigidly secured by bolts 83 to the inner portions of the hand levers. With this construction in mind, it is evident that when the levers 7 3 are o erated to raise the tool frame, the weight o the tongue acting through the spiral sprin i 81 assists in the operation; and, moreover, t e wei ht of the tongue is ordinarily fully sustained by the spring, thus relieving the necks of the draft animals of the burden, reventing sores.

Although have shown only the preferred form in which this invention may be embodied, I do not limit myself to this particular construction, as it is evident that many changes mi ht be made in the construction shown, without departing from the spirit of this invention or the scope of the appended claims.
