IMPROVEMENT IN Pnows.

' Specification forming part of Letters Patent No. 35,272, dated May 13, 1862.

To all whom it may concern: Y

Be it known that I, E. J. WHITE, of Locke,

in the county of Cayuga and State of New l spending parts in the two figures.

This invention relates to an improvement in that class of plows which are commonly termed gang-plows.7

The object of the invention is to obtain a simple and efficient device which maybe readily manipulated and adapted to plowing at variousdepths, becapable of being mounted on wheels, and all so arranged as to insure an easy draft and admit of any number of plows being used at the will of the driver or operator.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a horizontal frame or platform, which is mounted on two wheels, B B', the wheel B being larger in diameter than B", 4in

' `order to admit of the former running in the furrow and preserve the horizontality ofthe frame A. (See Fig".2.)

l C is the draft-pole, which is attached to the frame or platform A. On this .frame or plat- -form the drivers seat D is placed and six standards, E F G H I J. Through the upper` part of the standard E the fulcrum-pin a of a lever,K, passes, to the back end of which a `vertical plow-standard, L, is attached` by a pivot, b. The standard L passes through the frameor platform A, and is allowed to work freely up and down therein. To the lower end of the standard L an ordinary plow, M, is secured in any proper way. When this plow M is not required to operate it is raised above the surface of the ground by depressingthe front end of lever K and securing it in a notch in the lower part of the standard F. (See Fig. 2.) y

front part of said frame or platform there is a similar plow, Q, the standard R of which passes vertically through the frame or platform, and is connected at its upper end to the front part of a lever, S, by a pivot, d. The fulcrum-pin e of the lever S passes through the upper part of the standard H, and the front part of said lever, when the plow Q is elevated vvabove the surface of the ground, is titted in a notch in the lower part ot' the standard I. The colter T has its bar U also passing vertically through the frame or platform A, and is attached at its upper end to thefront part of a lever, W, which has its fulerum-pin f passing through the upper part of the upright J.

The driver from his seatD may operate any of the levers K N S W, and thereby raise either of the plows M Q and colters P T. The standards F I may be provided with a series iof notches, so that the levers K S may be'retained at different points and the plows M Q kept in a more or less elevated state, as may be required to plow the desired depth. `By this arrangement it will be seen that one or two plows may be used'at the will ofthe driver or operator, andthe depth ofthe furrows rgulated, as maybe required, with the greatest facility, and also the depth of the cut of the colters. The front part of the frame or platiorm A has a gage-wheel, X, attached, which is an important feature, as it prevents the front part of the machine being drawn down under the action of the front plow, Q, and consequently prevents the back plow, M, being unduly elevated. The wheel X therefore Tinsures the plows working a uniform depth in the soil.

Two or more plows may be used, as may be desired. I do not confine myself to any particular number.

Having--thus described my invention, what I ters P T and gage-Wheel X, all arranged for I claim as new, and desire to secure by Letters joint operation, as and for the purpose herein Patent, isset forth.

The plows M Q when attached to vertical 4 sliding standards, L R, which pass Ico e.y E' J' WHITE' through the mounted frame or platform A, Witnesses: and are connected to adjusting-levers K S, in J. O. STRYKER,

combination with the vertically-adjustable eol- GEORGE W. MAIN.
