IMPROVEMENT IN GANG-FLOWS.

Specilication forming part of Letters Patent No. 124,571, dated March 12, 1R72 antedated March 7, 1872.

y SPECIFICATION. To all whom 'it may concern:

Be it known that' I, GEORGE W. HAINES, of Maine Prairie, in the county of Solano and State ofOalitornia, have invented an Improved Gang-Plow 5 and do hereby declare that the following is a full and exact description ot' the saine, reference being had to the accompanying drawing and to the letters of reference marked thereon.

The object of my invention is to provide an improvement in that class of plows known as sulky gang-plows, and it consists, first, in an improved method of mounting the drivers seat, so that it is supported directly from the axle, thus relieving the plow-frame from much supertluous weight which has ordinarily to be 1aised. It further consists in a novel combination and arrangement of levers for elevating and depressing the ploWs and their frames 3 and also in an adjusting-gear, by which the plows are moved to or from the land and the axle of the'wheels is made to stand at an angle with the plow-frame, so that the line of draft can be more or less altered, as in plow- 1n g curves.

Referring to the accompanying drawing, Figure l is a side elevation, Fig. 2, a plan, Fig. 3, a bottom view.

To enable others yskilled in the art to which my invention most nearly appertains to make and use the same, I will now proceed to describe 'ully its construction and operation.

A A are the beams to which the plows are secured, and these extend forward over the axle sufficiently far to receive the rear end of the pole B, which is pivoted between them. The seat-standards O C extend down on each side of the beams A, and are secured to the axle D, so that the drivers seat E, which is secured to their upper ends, is supported directlyupon the axle. Thefurrow-wheel is made somewhat larger than the landside wheel 5 and it' it is necessary to still further depress the furrow-wheel for the `purpose of making the drivers seat stand level, it is done byraising the standard C and securing it, 'as desired, by means of a set or clamping nut, F, the bolt of which passes through a slot in the standard, as shown. The device for elevating the plows from the ground or depressing them into it consists of a compound lever, constructed as follows: A shaft, G, extends across the front of the seatstandards, turning in boxes affixed to them. At the ends ot' this shaft levers H project forward, and are connected by links I with a cross-bar, J, on the plow-frame. rlhis bar extends across the front ends ofthe beams A A, and is turned up at the ends to form suitable lugs for the attacln'nent ofthe links I. At one side the lever His continued back, forming an arm, L, which is connected with the operating foot-lever lll, by means ot' a link, N. This lever extends behind the link to a short distance, and is pinned to the side of the frame-timber A. A curved holding-rack, O, secures the lever at any desired point. When it is desired to elevate the ploWs, pressure is brought upon the foot-lever M, and this, through the levers and the links I,.elevates the front end of the plow-frame, which turns 'on the bolt that connects it with the pole, so as to stand at a small angle, and, by thus elevating the points of the plows, they will be easily drawn from the ground as the team moves on. At the same time the rear end of the lever M acts to elevate the rear end of the frame, so'that the plows, once started, are easily drawn out of the ground. An opposite movement of the lever depresses the points of the plow and causes them to enter the soil.l The axle has two arms, P I), seA cured to it near its outer ends, and these arms unite at a point, Q, beneath the pole where they are pinned to the rear end of a short le ver, It. To the front end of this lever is attached adraft-rod,'S,Which extends along bei neath the pole and terminates in a link, t, at the front. The lever It is operated by the stout pin U, which serves as its t'ulcrum and extends up through the pole. This pin is secured to the lever R below, and has an operating-lever, V, secured to it above the pole, so that, by simply moving the lever V to one side, the pin U turns the lever R; and by its action the arms P are so moved as to turn the axle so that it will stand at a small angle with the frame A. The front end ofthe lever It turns the rear end ofthe rod S to the opposite side from that occupied by the ends of the arms P; and thus the plows can be made to move so as to plow` a curved furrow. It' desired, the plo\v-frame A may be rigidly attached to the pole at dif ferent angles, by means of a pin which passes through the front cross-beam and enters the rear end of the pole.

By these different arrangements I make a plow very easy to opera-te, While the Whole combination is extremely eiiicient.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
