CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 468,271, dated February 2, 1892.

Application filed January 2, 1891. Serial No. 376.561. (No model.)

To all whom it may concern:

Be it known that I, SwAN SwANsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have nvented certain new and useful Improvenents in Cultivators; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in a new and improved cultivator which is light and strong in its construction and exceedingly effective in its operation; and the invention will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure l is a side elevation showing the carrying-wheels bearing the cultivator. Fig. 2 is a similar View showing the said wheels raised out of the way. Fig. 3 is a top plan view. Fig. 4 is a detail View of the levercontrolling the tongue. Fig. 5 is a transverse section of one of the rollers.

The same letters of reference indicate corresponding parts in all the figures.

Referring to the several parts by letter, A indicates the floor or platforn of the cultivator, and A' A' its side frames, in the lower part of which the rollers carrying the culti vator-teeth are nounted.

B B indicate the rollers,of which four are here shown employed, these rollers being .made of wood and having secured to their ends the metal cap-pieces or plates C, which are formed with the bearing-spindles C',which fit and turn in bearings in the lower part of the side frames A' A'.

The double-ended cultivator-teetl D are square in cross-section and are pointed and sharpened at each end. These teeth are driven diametrically through the Wooden rollers B, so that their ends project for an equal distance on both sides thereof, and the pointed ends of the teeth are curved forward, as shown, so that in operation they will leave the earth in a Vertical line as the machine is driven forward and the rollers revolve, as will be readily understood. Any number of rollers may of course be employed, according to the size of the cultivatonframe.

E indicates the axle, which is nounted in bearings on the platform A, as shown, and

raised up above the ground, as shown in Fig.

1, when the hooked inner end H' of a pivoted spring-actuated foot-lever H is pressed into the recess F' of the cam F, and this locks the Wheels securely in this position. The machine can then be drawn along the road with- 4 out the teeth of the rollers coming in contact with the ground. hen the field is reached, it is only necessary to press down the outer end of the foot-lever with the foot to release its hooked end from the notch F' when the weight of the nachine-body will lower it until the teeth D enter the ground, when the wheels E' will be raised up out of the way and will be held in that position by the hooked end of the lever catching in the recess F of the cam F.

On the under side of the inner end of the tongue I is bolted a casting J, and a pivotbolt K passes through this casting and through the inner ends of brackets L,bo1ted beneath the forward end of the platform A, the inner end of the tongue fitting and playing in a longitudinal recess A formed in the under side of that end of the platform. The inner end of the tongue is connected by a chain M with a hand lev'er N, which is pivoted at its forward end to the top of the platform, as shown.

'When the body of the cultivator is raised to draw the machine along the road, the inner end of the hand-lever N is raised and caught and supported on the recessed upper end of a short Vertical post 0, thus raising the inner end of the tongue and holding the tongue firmly in a horizontal position. Vlen, however, the cultivator is lowered into its operative position, the inner end of the hand-lever is disengaged from the recessed post O, leaving the inner end of the tongue free, so that its outer end can rise and give when the IOO the cranked ends, the Wheels nounted on said ends, the earn F, innovably secured on the axle and formed with the reoesses F' and 1 the raising and lowering lever G, secured to the axle, and the centrally-pivoted springactuated foot-level* H, formed With the inner looking end adapted to engage in the recesses F' and F of the axle-cam F, substantially as set forth.

In testimony Whereof I affix my Signature in presence of two witnesses.
