Letters Patent No. 106,161, dated Angus-t 9, 1870.

IMPROVEMENT IN CULTIYATORS.

The Schedule referred to in these Letters Patent and `making part of the same.

To all whom tt may concern v Be it known that I, SETE B. Ho1sn e11ox, of Galesburg, in the county of Knox and Stateof Illinois, have invented certain new and useful Improvements in Cultivators; and'I hereby dec-lare the fol lowing to be a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawing making a portion of this specification, inwhich- Figure 1 is a perspective view of my invention, and the main parts of a cultivator.

Figure 2 is a perspective view of the joint or coupling, detached.

Figure 3 isa back view of the device for attaching the shanks to the beams.

Figure 4 is a top View o1" iig. 3.

Figure 5 is a rear View of the device for adjusting the distance of the wheels and plows apart.

Similar letters of reference indicate corresponding parts in all of `the figures.

The nature of this invention relatcs'to improvements in cultivators; and

'Ihe invention consists in the peculiar arrangement for adjusting the distance of the plows apart, at the same time that the distance between the wheels is made to correspond therewith.

It further'consists in the simplicity and 'electiveness of the joint for connecting the plows t-o the main frame; also, in the manner of attaching the shanks to the beam, to render'thcm secureand adjustableyalso, in the simple construction and arrangement ot' the wheel-spindles, and in the general arrangement of the frame, tongue, and equalizer.

To enable others to understt'tmlfthe construction and operatiouof my invention, I will -procccfl to dcscribe itwith reference to the drawing.

Letter A represents the central and highest part of the axle, to which is attached the tongue and hands B' B", B being broken away to show other parts of the machine.

C G represent wrought-iron bars, crank-shaped, one end serving for wheel-spindles and the other for attaching to the axle A, while the central part serves to raise the axle A.

The upper part of the axle C is attached to the wooden part A by means of the eye-bolt I) and nutg, together-with bearings E E lil E.

By means of this arrangement, it will readily be seen, the distance of the plows and the distance of thc wheels apart may be easily adjusted by loosening the nut g, when the ,bar C may be moved, and, by tightening the same nut, the bar C will be drawn up tirmly and securely against the bearings J represents a cast-iron washer or bearing, slipped on to the wheel-spindle (Y, and heldin place by a pin, K, which passes through a recess in the back part ot `,the washer, and also through the spindle C.

L represents a similar washer to J, and is placed on the. end of the spindle C', being held in place by thev liuch-pin M, passing through a recess in' it. and through the spindle C.

The washers L and J have cach a recess in the faces toward each other, into which the boxes in the wheel-hubs tit, and preventsand and dirt from dropping in on the journals.

F represents the joint for attaching the plows to the' main frame, and is formed of two plates, held together mainly bythe bolt H, by means o which bolt they may be made to clasp tighter or looser the arms C', on which the plows have the lateral movement required in cultivators.

N represents a T-shaped plate, the stem ot' which is attached to the plow-beam, and the cross or' head N is provided with a series of holes, s s s s, through which passes thebolt Gr.

The head N is clasped between thc 'plates F, and the bolt G forms a pivot, on which vertical 'movement of the plows is obtained, while, by means of the bolt Gand holes s s s s, vertical adjustment or regulation of the depth of running may be obtained.

X X represent the shanks,l which are secured to the beam U by means of a socket, V, as shown in figs.v 3 and 4, recessed in the back part, through which the bolt y passes, and is tightened to the beam U` as required, by t-he nut v One end of the socket 'u lits snug and fiat to the beam, while the other end is grooved to tit neatly against the round shank X.

W represents a hook, the shank of which passes v through the socket c, and is secured thereto by a nut, w', the hook end partly encircling the shank X.

It will be readily seen that, by tightening thenut l1v', the shank` X willbe drawn' with any required tightness against the socket/v, and held securely from revolving, while at the same time the nut 'v' may be partially lloosened and the shanks swing round on the bolt, y, as a pivot, when required.

lZrepresents'a clasp, encircling the shank X, and secured by a bolt, a.

l h is a at rod, held between the ends of clamp z by a wooden bolt, a', and attached at t-hefbrward end to the beam U.

' In case of striking any very solid obstruction, the bolt c' will break andthe shank X swing back ou the pivot y, thus frequently preventing breakage ot' the plowor ot' the shank.

O represents a cross-bar, under the tongue B, and connected at the ends with the wheel-spindles C'by the rods '.l.

`Q represents vertical bars, pivoted ou the end of the cross-bar O, and connected at the upper end with the evcner-bar I) by the rods Il. The single-trees are attached to the hooks f.

'Having thus described my invention,

What I claim as new, and desire t0 Secure by Letters hook W, and nut W', socket V, bolt Y, and mit V'7 Patent, is. with shank X, substantially as and for the purpose 1.
