SPECIFICATION forming part of Letters Patent No. 395,098, dated December 25, 1888i.

Application liled July 2 5, l 8 8 8.

To all whom t may con/cern.-

jISe it known that I, WILLIAM .HENRY Wie- GINs, a citizen of the United States, residing at Lapland, in the county of Greenwood and State of Kansas, have invented a new and useful Improvement in Oultivators, ot which the following is a speciiication.

My invention relatos to an improvement in cultivators; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of a cultivato'i.' embodying my improvements. Fig. 2 is an elevation of the same. Fig. S is a verticaltransverse section of the same, taken on the line .r a: ot Fig. 2. Fig.. l and 5 are detail views.

A represents the tongue, on which at suitable distances from its rear end are secured a longitudinally-movable sleeves or boxes B. The same are coiinecteil on their under side by means o'l a rod, (l, which is arranged directly under the tongue.

D represents a transvm'se arm or bar, the central portion ot' which is secured on the tongue by means ot a clip, E. The said transverse arm or bar preferably made olf a piece ot gas-pipe or water-pipe, and the ends thereotl are curved downward and extended Yin a verticzitl direction and .l'orm sockets for vertical arms li, which project upward from bearings or boxes G. Said arms or spindles F are swiveled in the sockets at the lower ends of the cross arms or bars D by means'ot' transverse pin s Il, wh ich operate in segmental. horizontal slots I in the ends ot the cross bar or arm.

K represents a pair of axles, which are pret'- erably square in cross-section and on which are secured circular concavo-covex disks L. Sleeves ill of suitable length are slipped on the said axles and caused to bear between the said disks, so as to secure the same at suitable regular distances apart. The said axles K are rounded at suitable points near their inner ends, and said rounded portions of the axles are journ aled in the swiveled bearings or boxes G. The outer ends of the said axles are also rounded and reduced in diameter, and are j ournaled in bearings N, which Serial No. 281,026. (No model.)

are formed in the central portion ol" plates or shoes O, the ends of which are curved upward, shown.

The concave sides olf the disks on the two axles are arranged opposite to each other, and thereby the said disks are adapted to throw the earth inward toward the center of the machine when the same is in operation.

P represents a pair of brace-rods, which have their front ends bolted to opposite sides olf the tongue A, and which diverge rearward and have their rear ends rigidly secured to the ends oi" the arched arm or cross-bar D, the function ol' these brace-arms being to secure the said arm or cross-har rigidly 'in position.

The front ends olf the shoes or plates O are cminected to the Vlront sleeve or box, B, b v means otA link-rods R, and the rear ends ot' said pla-tes or shoes are connected to the rear f sleeve or box, M, by means of li nk-rods S.

T represents draft-rods, which. have their rear en ds secured to th e bearin G, and which extend forward thereli'rom and are adapted for the attachment oi the eve'nerebar or whifiietree, to which the team is hitched in the usual manner.

li represents a hainhlever, which is tulcrumed on one side of the beam and has its lower end pivotally connecl'ts'l to the rod C. The said hand-lever bears against one side ot a segment-plate or curved rack-bar, V, and is further provided with the usual spring-actu ated. 'locking-bolt, W, which is adapted to engage the said segmentplate and thereby secure the hand-lever at any desired position.

The operation of my invention. will be very readily understood. Then the hand-lever moved, the same imparts longitudinal move ment through the sleeves or boxes B to the rod C, and the link-rods which are attached to the longitudinally movable sleeves or boxes and to the shoes or plates O, at the outer end of the axle K, serve to turn the said axles in a horizontal plane, so as to arrange the disks at any desired angle obliquely with relation to the line of draft.

Then in operation, the machine is caused to run astride of the rows of plants, and by reason of the concave sides of the disks on the two axles being presented to each other IOO the saine are caused to thoroughly stir and pulverize the soil and throw the saine toward the row of plants.

A seat, X, for the driveiI supported over the tongue A by means of a spring-bar, Y.

Having thus described iny invention, l claiml. Thev combination of the tongue, the crossbar D, secured thereon and having the downturned ends, the brace-bars P, connecting said ends to the tongue, the bearings G, sWiveled in the ends of the cross-bar, the axles journaled near the inner ends in said. bearings and having' the concave-convex disks, the plates O, journaled to the outer ends ot' the axles, the sliding boxes or sleeves on the tongue, the link-rods connecting said boxes to the plates O, the lever to operate the said boxes or sleeves, and the d raft-rof'ls T, attached to bearings (l, substantially as described.

V2. The combination of the tongue, the crossbar secured thereto and having the downturned tubular ends provided with horizontal segmental slots l, the bearings G, having the stems F in the lower ends of the cross-bar, the pins H, Working in slots l and secured to the stems, the axles j ournaled in the bearings G and having the disks, the longitudinallymovable boxes or sleeves on the tongue, the link-rods connected to said boxes or sleeves and to the axles, for the purpose set forth, and the lever to operate the boxes or sleeves, substantially as described.

The tongue, the cross-bar or arm D, secured thereon and projecting outward transversely on each side of the tongue, the separate axles kjournaled in bearings fitted on the ends of the cross-bar D, the longitudinallymovable sleeves B on the tongue, the sets of disks on. the axles, and the connecting-rods between the sleeves land the separate axles, as set forth.

In testimony that I claim the foregoing' as my own l -have hereto affixed my signature in presence of two witnesses.
