SPECIFICATION forming part of Letters Patent No. 325,432, dated September l, 1885.

(No model.)

To all whom, t may concern.'

Be it known that I, STILLMAN A. MoULToN, a citizen of the United States, residingat San Jos, in the county of Santa Clara and State of California, have invented a new and useful Improvement in Gultivators, oi' which the following is a specification, reference being had to the accompanying drawings.

My invent-ion relates to an improvement in eultivators adapted especially for use in orchards; 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 drawings, Figure lis a side elevation of a cultivator embodying my invention, with the near wheel removed. Fig. 2 is a top plan view of the same. Fig. 3 is a front elevation.

The frame A of the cultivator consists, essentially, of the transverse beams B and C and the longitudinal connecting-beams D.

E represents brackets that are secured to the inner side at the center of the beams C, their securing-bolts passing through slots e that are made in the brackets. Similar slotted brackets, F, are secured to the upper side at the center of the front beam, B.

vGr represents a tongue, the rear end of which is bolted between the brackets E and F. v By reason ot' the slots in the brackets the tongue may be adjusted laterally to either side of the center of the frame, as will be very readily understood.

.H represents a bar that is hinged to one of the beams B, and on the upper side of this bar is secured a sliding bracket, I, having slots K, through which its securing-bolts L pass, and formed with this bracket is a segmental rack, M. A similar sliding bracket, N, having slots O, is secured on the opposite beam, B, by means of bolts P, and near the center of this bracket, in the forward portion thereof, is a vertical slotted standard, It. A curved rack, S, is formed with the rear end of the bracket X, and at the front end of said bracket is a pivotal lug, T.

U represents a double-cranked axle, which is journaled in the bracket I, and in the slotted standard of the bracket N. A hand-lever, V, is secured near one end of this axle, and engages with the segmental rack M.

A handlever, IV, pivoted in the stud I on the opposite side ot' the frame, is fulcrunied to the axle U, and engages with the curved rack S.

The supporting-wheels are journaled on the ends of the axle.

The rear beam, C, has its ends extending beyond the beams D, and on the under sides of these projecting ends are bolted keepers X, which are arranged diagonally, and are adapted to secure the inner ends ot" diagonal for wardly-projecting removable arms Y, on the outer ends of which are journaled removable circular disks or rollers Z', which are provided with cushioned rims.

Cultivatorteeth of any suitable construetion are secured to the beams B C D and to the arms Y, as shown. From the upper side of the tongue G, above the front beam, B, projects a headed stud, A, and similar studs, B', project from the upper side of the beam B on opposite sides of the tongue. C represents a drivers seat, the standard of which is provided with an opening, D', at its foot large enough to receive the heads of the studs A and B', and from tbe front side of this opening extends an open slot, E', of a correspond` ing diameter to the shanks of said studs. By means of this construction the drivers seat may be placed either at the centerof the frame, on the stud A', or upon either side thereof, upon the studs B, as will be very readily understood.

By providing the sliding brackets in Which the axle is secured, the axle may be moved at an angle to the eultivator-fraine for the purpose of changing the line of the wheels and enabling the cultivator to run close to the trees and to draw to one side, thus overcoming the side draft of the eultivator-teeth secured to the inner side arm, Y, when only one of said side arms is used. The purpose of the hinged bar H' and the slotted standards of the bracket N and the hand-lever iV is to enable the frame to be inclined, and thereby cause the teeth on the outer side of the frame to run deeper in. the ground than those on the inner side thereof when it is necessary to cause the inner teeth to run shallow in the ground in order to avoid disturbing the roots of the trees. The removable arms Y enable the cultivator-teeth to be extended so as to work under the branches of the trees where IOC the cultivator-frame could not be driven, and the cushioned disks on the ends of said arms are to prevent abrasion of said arms with the trunks of the trees, and thereby prevent in- 5 jury to the latter. The hand-lever V and the cranks on the axle enable the cultivator-teeth to be raised ventirely ont of the ground When not at Work, or to be lowered to any desired extent in the ground. ro Having thus described my invention, I

claiml. In a sulky-oultiv ator, the extending arms Y, having the cultivator-teeth, and the disks at their outer ends for preventing abrasion of 15 the trees, substantially as described.

2. The combination, in a sulky-cultivator,

STI LLMAN AUGUSTUS MOULTON.
