IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 30,892, dated December'll, 1860,

To all whom it may concern:

Be it known that I, OLIVER SPARKS, of Shelbina, in the county of Shelby and State of Missouri, haveinveuted a new and Improved Trench-Plow; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being bad tothe accompanying drawings, making a part of this specification, in which- Figure 1 is a side'elevat-ion of theimproved trenching-machine. Fig. 2 is a plan view of the machine with a section taken through the horizontal plane indicated in Fig. 1 by the red line 00 00.

Similar letters of reference indicate corresponding parts in both figures.

This invention is an improvementin trenchplo'ws.

It consists in combining in a novel manner -a breaking or sod plow with a trench or subsoil plow, whereby both plows may be thrown into or out of the ground simultaneously.

The principal object of the invention is to more perfectly bring the subsoil to the surface and cover up the sods or surface-soil, as will be hereinafter described and represented.

To enable'those skilled in the art to fully understand my invention, I will proceed to describe its construction and operation.

In the drawings, A is the mold-board of an ordinary turn-plow. B is its standard for attaching it to the beam B; and a is the landside-bar, from which proceeds perpendicularly upward the guide-bars b b, which are'carried above the rear end of beam B, bent over, and attached securely to the beam each side, and braced by plates 0, Fig. 1.

In front of the turn-plow is placed a rotary colter, (1, attached to the foot of standard 0, and in front of this colter are two wheels on an axle-tree, D, on which the front end of the machine rests. One of the wheels is made of a larger diameter than the other, as one runs in the furrows and the other on the unplowed land.

E E are standards which project up from the axle-tree D and support one end of the long hand-lever F and the lever G, to which the front end of the beam B is jointed.

E E are standards attached to and projecting up above the beam B, to which thelever F may be secured by a pin or other means when it is in an elevated or in a depressed state. The lever G has a slot out in its end in a direction with its length, and through this slot passes a pin that pivots the lever to a pendentrod, G, which is attached to the hand-lever F.

H is a slotted lever, the slotted end of which is attached by the same pivot to the pendent G and to the lever G. This lever H has its fulcrum in the standard E E, and its other' man who manages the trench-plow. Its object is to enable the plowman to elevatethe points of both plows at the same time or 'to depress both points simultaneously. He may by this means regulate thedepthit is desired theplows should run in the ground. The front plow runs sufficiently deep to cut and turn the sod or surface soil. The rear plow then follows in its furrow and brings up the subsoil and turns it over the sod which has been previouslyturned,

.thus completely turning the soil and burying the surface-sod.

Having thus described my iuvention,\vhat I claim as new, and desire to secure by Letters Patent, is

The two plows arranged one in front of the other, as and for the purposes herein set forth, in combination with the levers F, G, H, and G,

arranged, supported, and operating as herein described.

OLIVER SPARKS.
