CULTIVATO R. 4

SPECIFICATION formingpart of Letters Patent No. 253,869, dated February 21, 1882.

- Application filed October 4, 1881. (N model.)

To all whom it may concern Be it known that I, JAMES HERVA J owes, a citizen of the United States, residing in the city of Rockford, in the county of Winnebago and State of Illinois, have invented new and useful Improvements in Cultivators, of which the following is a specification.

This invent-ion relates to improvements in that class of agricultural implements known as cultivators. Its object is to improve this class of implements to render them a more effi- -cient and convenient implement.

a plan view of a cultivator embodying my invention, of whichFig. 2 is a side elevation in which the near wheel is omitted. Fig. 3 is a lateral central section of the two-part jointed raisingand holdinglever on dotted linear. Fig.

' dis an isometrical representation of the hinged forward end portion of the jointed two-partraising and holding lever,in which a portion is cut away to more clearly show its construction. Fig. 5 is a side elevation of the friction slip-support of the shovel-standard, with the clasp of its upper end removed. Fig. 6 is aside elevation of the friction slip-support of the shovel-standard with the clasp of its upper end removed and the parts in their open position. Fig. 7 is a transverse section of the frictional slip-support of the shovel-standard cut on dotted line 3 Fig. 8 is an isometrical representation of the bed portion of the standard-support. Fig. 9 is an isometrical representation of the pivoted portion of the standard-support, and Fig. 10 is 'an isometricalrepresentation of the pivoted friction-lever of the standard-support.

In the figures, A represents an axle-tree having crank-formed axle-arms B fixed to the under side of its end portions; I

At 0 are represented carrying wheels, mounted to revolve on the axle-arms.

AtD are represented tongue-beams, having their rear ends fixed to the axle-tree and their forward ends joined to each other and fitted to receive a neck-yoke.

At E is represented a transverse bar fixed to the under side of the tongue-beams to give support thereto, and to which the whiffietrees are to be attached. These parts constitute the supporting-frame of the cultivator.

At Fare represented seat-supportin g beams, fixed at their forward ends to the tongue-beams and extending rearward over the axle-tree, having mounted on their rear ends a drivers seat, G, which is made lengthwise adjustable thereon. 7

,At H are represented pendants connected with the transverse bar E, and rearward thereofto the tongue-beams At I are represented drag-bars having their forward ends fitted with a joint mechanism, K, adapted to enter the free end portion of the pendant, to produce a suitable jointconnection therewith. v At K is represented an arching bar, having its end portion pivoted to the drag-bars, operating to control their relative lateral movements; and in combined riding and walking machines, where handles are employed fixed to the drag-bars, I employ the usual transverse rod to connect the handles.

All of the foregoing-described parts are substantially the same as like parts to be found in machines heretofore patented to me, and are constructed and joined in substantially the same manner and for the same purpose.

At L is represented a safety-slip support, employed to fix the shovel-standard, with its shovel attached, to the drag-bar. In this safety-slip support, a represents the bed-plate,

which is of the peculiar form represented in the drawings, having its center portion, I), which extends obliquely across the vertical face of the drag-bar, of outward-curvingformin section; andits opposite sides are provided with outward-projecting wings 0, having their end portions fitted with a series of holes, d, through which sufficient screw-bolts are passed to fix it in position on the drag-bar, and by means of which its position thereon may be varied to change its angle with relation to the drag-bar or to change the angle of the shovel relatively with the surface to be cultivated, which change or changes are produced by ehangin g the bolts formed recesses or depressions c".

to any of the holes d in the series. The lower portion of this bed-plate is provided with a conic-formed socket, 0, having its opposite? side walls provided with. lateral projecting wings e. In the outer surface of these wings are The upper end portion of this bed-plate is provided with a hole, 0', surrounded on the outside of the bedplate with an uprising boss, 0.

At his represented the pivoted lever portion of the support, to which the standard is fixed. This pivoted leveris of the form shown, having its lower end portion provided with a conic-formed tubular stud, h, of proper dimensions to enter the conic-formed socket e in the bed -plate, forming its pivotal support, and when in position therein its upper tapering endportion, It, will extend nearly to the hole 0' in the upper end of the bed-plate. The outer face of this pivoted lever portion is provided with a flange, h, rising from its outer edge and encircling the conic opening in the conic stud. In this flange are formed concave seats 5, adapted to receive the round shovel-standard 2'.

At It is represented an eyebolt the eye of which receives the shovel-standard, and its screw'threaded shank portion extends through the tubular conic stud, and is fitted with a washer, 7c, and a screw-nut, k, by which the standard is firmly clamped in the pivoted lever, and the lever, with the shovel-standard fixed therein, is held in its pivotal connection with the bed-plate to turn or swing thereon.

At 1 is represented a friction-lever, having like sides, and its form is clearly represented in the drawings. Its upper end is fitted with a hole, L, to correspond with the hole in the upper end of the bed-plate, and its sides are provided with countersinks L", adapted to receive the boss 0. The hookingportion of this lever, near its fulcrum-support, is provided with a curved notch, L, adapted to receive the free end h of the pivoted lever, operating substantially as a gear-tooth. The lower free end of this friction-lever is provided on its opposite sides and inner edge with enlargements m, adapted to engage the depressions c in the wings of the conic socket.

At m is represented aclevis-like clasp, made from plate material, and of proper dimensions to span the upper end of the bed-plate and friction-lever, and is fitted with holes to correspond with the holes in the bed-plate and friction-lever.

At m is represented a screw-bolt, which is passed through the clevis-like clasp, the bedplate, and the friction-lever, and by means of its screw-nut operates to hold and clamp the parts in such a manner as to hold the shovel M fixed to the lower end of the shovel-standard sutficiently rigid for the purposes of cultivation, but under severe strain will yield and permit the shovel to turn back to prevent breaking.

It will be. readily seen from the foregoing description that if the shovel when in use meets a rigid obstruction, the action of the upper end of its pivotal support operating against the pivoted friction-lever by means of its toothlike connection, will disengage its free end from the depression in the lateral wing of the conic socket, when the parts will move freely to their position, as represented in Fig. 6, and permit the shovel to override the obstruction without injury, after which, if the drag-bar be raised to a sufficient height, a sudden forward efiort upon the shovel to swing it forward will return the parts to their working position, as represented in Fig. 5.

The force with which the shovel is held in its working position is regulated by means of the clamping-screw, which operates to hold the free end of tho friction-lever in the depressions in the lateral wings with more or less force, as the nut of the clamping-screw is turned in one or the other direction.

It will also be observed that by means of the eyebolt connection of the shovel-standard with the pivoted lever the shovel by means of its standard may be raised and lowered or turned to cast the earth to either side to or from the plants. The several parts of this shovel-holdin g mechanism are of such construction as to render them capable of use on either side of the drag-bar, and are capable of use on perhaps about all varieties of cultivating implements requiring a safety-slip or turn-back tooth.

At N is represented asaw-toothcd segment ratchet of the form represented, having like sides and capable of use on both sides of the machine, and fixed in position thereon to the tongue-beams by means of sufficient screwbolts.

At P is represented the handle portion of the lifting and holding lever, consisting of a wood hand portion, a, fixed to a metallic portion, a. This metallic portion n is provided with flanges n, projecting outward from its edges to embrace the edges of the wood portion, and they extend partially around the fulcrum-center of its forward end, leaving an open space, 12', between the forward ends of the flanges. This portion of thelever and also the forward upper portion of the ratchet are provided with suitable holes, 0, to receive the tubular stud-journals of the pivoted forward end portiomlt, of the lever. This forward end portion of the lever is of the form shown, having its rear end portion provided with opposite tubular studs 0, projecting laterally from its opposite sides,'of proper dimensions to freely enter the holes 0 in the ratchet and forward end of the metallic portion at of the lever, and when in place a screw-bolt, 0, provided with suitable washers, is passed through the tubular studs, and by means of its screw-nut serves to fix the parts in position, having a pivotal connection with each other. I

The forward portion, R, of the lever is provided with a flange, 0", rising from its outat of the lever on its inside is provided with an inward-projecting portion, t, provided with saw-toothed catches to engage the teeth of the ratchet to hold the lever in its adjusted position.

At t is represented a rod having its central portion produced in spiral-spri n g form, and is placed to span the space between the levers on. the opposite sides of the machine, having its ends connected with the levers, operating by its spring action to hold the levers engaged with the ratchets. From this arrangement it will be seen that by means of the levers the operator mounted in his seat will be able to I raise or lower the drag-bars, which will be held in their adjusted position by means of the lever-engagement with the segment-ratchets in such a manner as to prevent their descent, but by means of their connection with the pivoted forward end portion of the lever will be permitted to rise within the limits of its independent movement, as represented in the dotted lines in Fig. 2. By this construction of the lever I dispense with the usual suspensionchains, and employ the rods p in their stead, which, when the beams are raised for transportation, willengage the outside of the tonguebeams, and operate to limit the lateral swaying of the beams, and prevent the shovels engaging the 'wheels. This feature renders the working of the cultivator much more flexible, and is found to'be of I great value in what is known as a combined riding and walking cultivator. The parts of this lever are of such construction as to render them capable of use on either side of the machine. This featurein the construction of the lever, the ratchet, and the standard-support is found to be a valuable feature in the construction and in the repairing of the machine.

I am "aware that it is not broadly new to provide a jointed or two-part raising-lever, and

hence I make no claim to such aconstruction, broadly considered. a

I claim as my invention' 1. In a cultivator slip-tooth, the combination, with the bed-plate, of a lever-support for the sho vel-standard pivotally supported in a hearing of the bed-plate, a slotted lever for holding the support, and a screw-eyebolt adapted to receive the shovel-standard, and connect the standard-lever and bed-plate, substantially as set forth.

2. The combination, with the bed-plate and the standard-support, the latter being pivoted to the bed-plate, of a friction-lever pivoted on the bed-plate, and having a gear-tooth connection with the standard-support, substantially as set forth.

3. The combination, with the bed-plate and with the lever-standard support having apivotal connection therewith, of a friction-lever having a screw-clamping bolt, pivotal connection with the bed-plate, and a gear-tooth connection with the lever-support, substantially as and for the purpose hereinbefore set forth.

4. The combination, substantially as herein described, of the bed-plate capable of use on either side of the drag-bar, a lever-standard support and standard, having a screw-eyebolt pivotal connection with the bed-plate, and a friction-lever having pivotal clamping-bolt connection with the 'bed-plate'and a gear-toothlike connection with the pivoted lever-support, substantially as and for the purpose hereinbefore set forth.

5. The combination, with the bed-plate and the standard-support, of the pivoted frictionlever, having a gear-tooth-like connection with the said support, and provided with an enlarged end adapted to engage with the bedplate, substantially asset forth.

6. In a cultivator,the combination, with the main frame, a ratchet-segment mounted thereon, and a drag-bar, of a two-part raising and holding lever, having a handle portion and a pendent portion capable of a slightupward movement independent of the handle portion, and a link connected to the lever and to the drag-bar, substantially as set forth.
