SPECIFICATION forming part of Letters Patent No. 552,074, dated December 24, 1895.

Application filed. July 5, 1895. $erial No. 564,947. (No model.)

To aZZ whom it may concern.-

Be it known that I, VIRGIL G. RICHEY, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cultivators; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in garden-cultivators, the several features of which will be fully hereinafter described and claimed.

The object of my invention is the construction of a cultivator which will be readily adjustable laterally to suit rows of varying widths, and also adjustable as to the depth the hoe may penetrate the soil.

The mechanism is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the implement. Fig. 2 is a plan of the same with some parts omitted. Fig. 3 is an enlarged detail plan of the handle part.

Like letters and numerals designate like parts in all the views.

The wooden handles A are of the usual form and are connected to the spindles O by the supporting arms L. These arms are bolted to the sides of the handles and have orifices, into which are fitted said spindles. The handles at their outer ends are connected by two cross-bars 10 and 11 and the diagonal braces 8 and 9. The outer ends of said diagonal braces are bolted to the under sides of the handles, and the inner ends are bolted to the cross-bar 10, which has slots 12 in the ends, and which construction admits .of the adjustment which is effected by the axle D. This axle comprises two bars, the lower ends being bent under and rigidly bolted to said supporting-arms. They extend vertically a suitable distance, bent at a right angle and terminate in loops,which embrace each other, and the pin 13,which passes through the two parts and bind the same. To effect the lateral adjustment of the hoes these parts slide upon each other and are bound by the pin,

as before specified. The two arms E are in the form of an obtuse angle, and at the points of their angles are provided orifices, which embrace the spindles and upon which these arms freely move. In their lower ends are held within orifices the round bars I and on the inner ends of which areheld the hoes G. The top ends of these arms are notched or an orifice may be provided, into which is placed the stirrups if, only one of which is shown in the drawings, the ends of which are rigidly fastened to the plate 1, which is loosely held on the rod F. To this rod is fixedly attached the plate 2, and between said plates the two spiral springs 3 bear. In bearings on the cross-piece 11 is held the rod H, and to this rod are rigidly attached the arms J, and the rods F connect these arms with the pivotal arms E. The arm 5 is attached to the outer end of said rod, and to thisis attached the locking-plate 4, which is pressed down by the fiat spring 6, and the pin of which engages the notched plate 7, which is attached to the handle, and by this means the hoes are adjusted as to the depth of penetration of the soil.

The usual form of cultivator-hoe G or any other form, if provided with an orifice, may be secured to the rod I by a set-screw, which enters a countersink of said rod, (not shown in the drawings,) and the same is secured to the arm E in the same manner to prevent any rotation. The axle is adjustable to fix the position of the ground-wheels, the handles likewise to accommodate the former adjustment, and the hoes are readily adjusted laterally-to suit the rows of plants by moving the hoes along the sustaining-rod.

In operating the implement it is simply pushed along over the rows of vegetation to stir the soil after the several adjustments are made, as the circumstances may require. The depth of penetration is regulated by the lever or arm 5, as the farther it is drawn back the deeper the penetration.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. In a garden cultivator the combination of the handles A, the wheels G, the supporting arms L, the adjustable axle D secured to said arms, the spindles O, the pivotal arms E, 'the stirrup tWith its plate, the rod F with its plate, the spiral springs 3 between said plates, the rods I, held in said pivotal arms, the hoes G held on said rod, the arm 5 with its engaging-plate 4C, and the notched plate 7 attached to the handle, substantially as described.

2. In a garden cultivator the combination of the pivotal handles A, the adjustable frame D, the ground Wheels 0, the arms E held" on
