SPECIFICATION forming part of Letters Patent No. 788,233, dated April 25, 1905.

Application filed July 5, 1901. fierial No. 67,135.

To all whom it may concern:

Be itknown that I, SAMUEL L. ALLEN, acitizen of the United-States, and a resident of Moorestown, 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 part of this specification.

This invention relates to certain improvements in cultivators, and particularly to that class known as riding-cultivators, by which a number of rows are worked at one time.

The main object of this invention is to generally improve and simplify the construction of machines of this character and to increase their efliciency and utility in various ways, such as hereinafter fully set forth.

The various other objects, uses, and advantages will be readily apparent by reference to the description and accompanying drawings, which form part of this specification.

Referring to the said drawings, Figure l is a plan View of amachine constructed in accordance with my invention, the cultivating-tools being removed from the tool-carrying frame. Fig. 2 is a sectional elevation taken about on the line 2 2 of Fig. 1. Fig. 3 is a front view, partly in section, illustrating the seat-supporting frame. Fig. & is a sectional elevation taken about on the line 4: 4 of Fig. 1. Fig. 5 is a front elevation of the forward portion of the supporting-frame. Fig. 6 is adetail perspective view of the movable side rails of the supporting-frame, illustrating the manner in which they may be adjusted to change the width of the machine. Fig. 7 is a detail perspective View of portions of the tool-carrying frames, showing the manner in which they are supported by the main frame of the machine. Fig. 8 is an enlarged detail per spective view of one of the tool-carrying standards, showing the manner in which they are clamped to the tool-carrying frame. Fig. 9

is a detail perspective of the clamp which secures the tool-standard to the carrying-frame. Fig. 10 is a detail section showing the manner in which the clamp secures and holds the toolstandard to the tool-carrying frame. Fig. 11 is a detail perspective illustrating a slightly-modified construction of the box to which the clamp is secured. Fig. 12 shows another modification of this box, also a modified form of clamping-plate.

In carrying out my invention I provide a supporting-frame comprising a front bar 1, rear bar 15, and connecting-bars 18. The front bar 1 is preferably made of angle-steel, which passes under the tongue 2, as most clearly illustrated in Fig. 5 of the drawings. This bar 1 has secured to its central portion a U-shaped strap 3, which passes over the tongue and is pivoted thereto by means of the horizontally-disposed pivot-bolt 4:, this forming the fulcrum upon which the supporting-frame moves during the raising and lowering of the said frame, as will be hereinafter described. Aflat steel bar 5 is secured at each end to the top of the bar 1, the said bar passing over the U-shaped strap 3 and being secured at its center to said strap by means of the bolt 6. Adjacent to each end of the bar 5 are formed the loops 7, into which are secured the ends of the brace-bars 8, the other ends of which are bolted to the sides of the tongue 2, as illustrated in Fig. 1 of the drawings. The supplemental bars 9 are provided for further bracing the tongue, being secured by suitable bolts at one end to the tongue and at their other ends to the brace-bars 8.

The side frames of the machine comprise the flat steel bars 10, spaced apart by means of suitable blocks 11 and having their forward ends secured to the front bar 1 by means of suitable bolts 12. This bolt 12 passes through an elongated slot provided in the bar 1, as illustrated in Fig. 6 of the drawings, and is for the purpose of allowing the said side bars to be moved inwardly when it is desired to change the width of the machine. The other ends of the side bars 10 are secured, by means of the bolt 13, to the tool-carrying bars 14, one of said bars resting on top of the tool-carrying frame and the other resting on the bottom, as illustrated in the drawings.

The tool-carrying bar comprises three sections 14, 15, and 16, each section being composed of two parallel bars closed at each end by a spacing-block, or they may be made of a single bar of steel bent at their ends and welded together at their meeting ends, if it should be desired. The side sections 14 and 16 are secured to the intermediate section 15 by means of a strap 17 and the frame-bars 18, one of which bears against the upper side of the strap and the other against the lower side, and these parts are bolted together by means of the bolts 19. The forward ends of the twin frame-bars are secured to the front bar 1, as illustrated in Fig. 1 of the drawings.

The supporting-wheels 20 of the machine are mounted on the crank-axles 21, the inner ends of each crank passing into a tubular pipe 23, which forms the middle section of the axle. On the upper horizontal portion of each of the cranks 21 is loosely mounted a casting 24, having a bore formed in its lower portion which the crank fits into, and the upper portion of said casting has formed thereon two brackets 25 and 26, which support the two frame bars 18, the said bars being bolted to the said brackets, as illustrated in Fig. 4 of the drawings. These frame-bars 18 are located on each side of the machine a short distance inside of each of the supporting-wheels 20. It is obvious that the castings 24 may be carried on the ends of the tubular portion 23 with the same result, it only being necessary that the intermediate portion of the axle be pivoted in relation to said castings 24.

Secured to the lower member of each of the frame-bars 18 is a segmental rack 27 the said rack being engaged by the usual spring-pawl carried by the operating-levers 28. On the upper horizontal member of the crank-shaft 21 is mounted an angular plate 29, having an aperture through which the crank-shaft passes and having its lower arm bent outwardly and bolted to the perpendicular section of the crank 21, as illustrated in Figs. 2, 3, and 4. The upper arm of this plate 29 has secured thereto the lower end of the operating-lever 28, so that as the said operating-lever is moved rearwardly the crank 21 is thrown downwardly and the rear portion of the frame carried with it, the said frame swinging, on the pivot 4, before described, this operation causing the toolcarrying frame to be lowered, and consequently causing the teeth to enter the ground the desired depth. Upon moving the operat ing-lever 28 forwardly the crank 21 is lifted and serves to raise the tool-carrying frame to Fig. 1 of the drawings and spaced apart, as illustrated, so as not to interfere with the central lever mechanism, which has not as yet been described,but which moves laterally when one side of the machine is raised independently of the other. This frame 30 is preferably made of a single bar of metal bent to the desired shape and closed at its ends by means of a transverse bar 32. The forward end of the frame 30 is pivoted at 33 to a U-shaped clip 34, the ears of the said clip 34 being pivoted at 35 to a clip 36, which is in turn pivoted, by means of a bolt 37, to the tongue 2, thus forming a universal joint. The object of this construction is to allow of the raising of one side of the machine, which throws the frame on an angle without tilting the seat-carrying frame and seat, this frame always remaining straight no matter what may be the position of the main frame of the machine. The pivoted frame 30 is supported by means of the inclined bars 88, which are secured to the bars 31 at 39 and have their lower ends bent at an angle and secured to a collar 40, which is loosely mounted on the crank-axle 21 directly inside of the hub, as clearly illustrated in Fig. 3 of the drawings, thus throwing the weight of the driver on the supporting-wheels and preventing him from having to raise his own weight.

On each side of the tongue 2 are bolted the bars 41, which are bent inwardly at the end of the tongue and run rearwardly some distance beyond the said tongue, as illustrated in Figs. 1 and 2. Between these two bars 41 is secured a segmental rack 42, and pivoted at 43 is an operating-lever 44, having the usual spring-actuated pawl, which is adapted to engage the notches of the rack for the purpose of locking the lever in a fixed position. The lower portion of the lever 44 be 0nd its pivot 43 is bent at an angle forming an arm 45, the free end of which is pivoted to the bracketarms 46, carried by the intermediate portion 23 of the axle. The object of this lever is to even up the forward and rear rows of teeth, so that they will both enter the ground the same depth when the frame has been thrown down by the action of the side levers 28. This lever 44 when operated also serves to regulate the height of the tongue and will regulate or even up the teeth whether the tongue is carried low or high by the team.

The lever 44 when moved forward throws the tongue slightly forward and also lowers the same a short distance. This movement tilts the rear end of the machine-frame upwardly, thereby raising the rear tooth and evening it up with the forward tooth, so that the depth of cut, of each row of teeth will be the same. During transportation it is desired to raise the teeth some distance above the ground, and this is done by means of the side levers 28, which are moved forwardly, thus raising the rear end of the machine-frame,

and by operating the lever 44 in a forward direction the rear end is raised, so that both side levers and central lever serve to raise the frame and teeth from the ground.

The seat-supporting bars 38 are secured at their lower ends to the collars 40, which are loosel secured on the crank-axles below the fulcrum of the side levers, so that the weight of the rider is supported directly by the wheels of the machine and is not lifted when the side levers are operated in a forward direction to raise the tool carrying frame. When the soil is very hard, some difliculty is experienced in forcing the cultivator-blades into the same, and in this event the side levers are thrown back to the limit and locked in this position, which action raises the wheel from the ground, thereby throwing the whole weight of the machine on the teeth, which forces them into the ground, and as the machine moves forward the wheels will come in contact with the ground again after the teeth have penetrated the same to the proper depth.

It is very often desirable to raise one side of the machine independently of the other, which throws the tool-carrying frames at an angle. The construction and arrangement of the seat-frame 30 and its universal-joint con nection to the tongue permits this frame to remain in its normal position at all times no matter what may be the angle of the tool-carrying frame. Sufficient space is left between the tool-seat-supporting bars 31 to allow the segment 42 and lever 44 to have suflicient play laterally when either end of. the frame is inclined.

WV hen it is desired to lessen the width of the machine, the bolt which passes through the slot 12 and secures the side bars 10 to the front frame-bar 1 is loosened up and the bolts 19, which secure the frame-bars 18 to the tool- frames 14, 15, and 16, are also loosened up and the two end sections 14 and 16 can then be moved inwardly until the side bars 10 are in a plane with the draft-line of the machine, as illustrated in detail in Fig. 6 of the drawings. The bolts 19 are then tightened up and the teeth-standards adjusted accordingly on their carrying-frames.

The upper ends of the tool-standards are provided with boxes 47, made of sheet-steel struck into the desired shape. These boxes are provided on one end with an angular shoulder 48, of a size sufficient to fit the crosssection of the tool- bars 14, 15, and 16. A slot 49 is located in front of the shoulder 48 a distance therefrom equal to the distance between the two members of the tool-carrying frame, and the slot 49 is of a width sufficient to admit one of the said bars 14, 15, or 16. When these boxes are placed in position on the tool-carrying frame, the middle section 50 will fit snugly between the two bars, as illustrated in dotted lines in Fig. 8 and in crosssection in Fig. 10 of the drawings. A bolthole 51 is provided in the section 50 of the box. Aclamping-plate 51', such as shown in Fig. 9 of the drawings, is provided having a slotted end 52, through which the clampingbolt 53 passes. The other end of the plate 51 is turned over at 54 and when in position embraces the under side of the top plate of the box.

In placing the standard on the tool-carrying frame the box 47, carried or formed on the upper end of the said standard, is placed between the parallel bars 14 in the manner above described, and the clamping-plate 51 is then placed in position, the slot 52 embracing the bolt 53 and the turned-over end 54 extending under the top of the box, as before described. By tightening up the nut 55 the standard is drawn up until the lower edges of the shoulder 48 and the slot 49 bind against the under side of the frame-bars 14. When it is desired to remove the tool-standard, it is simply necessary to loosen up the nut 55 and then withdraw the clamping-plate 51 from engagement with the bolt 53, when the standard will then drop from between the two rails 14, the bolt 53 and nut 55 remaining in the box 47.

in Fig. 11 the box 47 is shown as being formed of a separate piece and riveted to the tool-standard, this being the form used on rear-teeth standards. In Fig. 12 I have shown a modified form of box and clamping-plate. In this construction the box is made in a single piece closed at its bottom and having its free ends bent and overlapping each other to form the top. The clamping-plate 59 shown in connection with this modification comprises a flat steel plate having provided therein two bolt-holes, and the box is also provided with two holes which register with those in the plate 59. The bolts 56 57 pass through these openings, and the parts are clamped together by means of the nuts 58. When this construction is used, the box 47 can remain on the tool-carrying frame and the standard is simply slipped in the lower portion of the box under the parallel bars 14, after which the nuts 58 are tightened up, thus securely binding the standard against the lower edges of the bars 14.

From the foregoing description it will be readily seen that l have provided a machine which is strong and durable and one which can be easily adjusted to change the width of the machine, so as to work a large'amount of ground at one time by simply loosening up a few bolts and sliding the adjustable tableframes 14 and 16 inwardly. 1 have also provided a machine the tool-carrying frame of which can be readily raised on one side independently of the other side, which is especially advantageous in orchard-cultivating when it is desired to lessen the depth of penetration of the teeth when working close to trees, so that the roots may not be damaged. The construction and arrangement of the seat-carrying frame is such as to keep the seat in a straight position, no matter which side of the tool-carrying frame may be elevated. This seat-frame is also so arranged and constructed as to throw the weight of the rider directly on the supporting-wheels of the machine, so that in raising the tool-frame the weight of the operator does not have to be lifted.

Various slight changes in the details of construction might be made without departing from the spirit and scope of my invention. Hence I do not desire to be limited to the exact construction shown and described.
