JOHN 0. BROWN AND G. H. SLIMPERT, OF FINGKNEYVILLE, ILLINOIS.

IMPRGVEMENT IN GANG-PLOWS.

To all whom it may concern: I

Be it known that we, JOHN 0. BROWN and G. H. SLlMPERT, both of Pinckneyville, in the county of Perry and State of Illinois, have iuvented a new and Improved Gang-Plow; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is an elevation of one side of our improved plow. Fig. 2 is an elevation of the opposite side of the machine. Fig. 3 is a top view of the machine with the driversseat removed. of the machine with the ends of the plowbeams broken away.

Similar letters of reference indicate corre sponding parts in the several figures.

Our invention relates to that class of maehines in which two transporting-wheels are employed in conjunction with plows which are arranged in gangs one behind the other, the wheels being so constructed and applied to the frame of the machine that one of them will runover the nnplowed land and the other in the furrow, at the same time keeping the machine level.

One object of our invention is to prevent the plows from being lifted out of the ground when. the land-wheel moves over rising and falling land or across corn furrowed land.

Another object of our invention is to facilitate the turning of the machine by making the land-wheel a caster-wheel and locating it in rear of the axle of the furrow-wheelandalongside of the plow which is on the landside of the machine, as will be hereinafter described.

Another object of our invention is to employ self-locking levers in conjunction with plowbeams whose ends are allowed to rise or fall, said levers being so arranged and applied that the driver, while riding upon the machine, can elevate the plows and lock them in such position or depress the plows, and, when desired, adjust them toward or from the landside of the machine at pleasure, as will be hereinafter described.

Another object of our invention is to secure the plows to beams which are pivoted to the frame of the machine in such mannerthat the Fig. 4 is an elevation of the rear end points of both plows are about the same distance from the pivotal connections of their respective beams for the purpose of enabling both plows to run at the same depth in the,

To enable others skilled in the art to under 7 stand our invention, we will describe its con struction and'operatiou. y

The frame of the machine consists of two longitudinal beams, A A, which are secured in position parallel to each other by transverse braces, which braces also sustain a platform, A This frame is mounted upon two transporting-wheels,B and O, and constructed with a view ofapplying the draft-pole to it in such manner as to avoid side draft upon the team as much as possible. This draft-pole Dis secured to the frame by means of transverse bolts a a ,,which also assist in strengthening the frame.

The drivers seat is mounted upon asta-ndard, E, at the back of which is a frame, Gr, havin g two vertical slots through it, through which the p10w=beams F F pass, as shown in Figs. 3 and 4. These slots are of sufficient length to allow the plows to be lifted up free from the ground, as shown in Fig. 1, or depressed and made to run in the ground, asin Fig. 2, and

the slots are of sufficient width .to admit of all the lateral adjustments of the plow-beams re quired. The plow-beam F, which'is onthe furrow side of the machine, is pivotedzor connected by a bolt to a perforated rocking bar, a, which is pivoted at its ends to the longitudinal beam A and an intermediateylongitudiual beam, A3, as shown-in Fig. 3, and the plow-beam F, which is on the landside of the machine, is pivoted or otherwise connected to a transverse rocking bar, a, which is pivoted,

some distance in rear of bar a, to the beams A and A The two plow-beams F F vary in length in proportion tothe distance between thetwo rocking barsa a, and carry on their rear ends the plows H H, which may be made of the most approved form.

The standards b b of the plows consist respectively of a vertical portion and a horizontal'portion, which latter is used in securing the plows in the desired position to the beams. These standards are secured by pivots at c c and by set-screws at 0 0 which latter pass through slots which are made through the standards. By loosening the screws 0 c the plows can be set at any desired pitch without detaching. them from their standards. The plows are secured to their standards so that one plow, H, will be in advance of the other, H, and so that they will be at equal (or nearly so) distances from the pivots of their respective beams. By this arrangement of the plows and beams the former can be raised out of the ground or made to enter the ground together.

. They will also run at a uniform depth in the ground, whereas if the plow-beams were of difl'erent lengths, or the plows attached to them, as hitherto, the latter would not enter or leave the ground simultaneously.

On the rear side of the frame G are two slotted guides, d'd, through the slots of which the plow-beams pass, as shown in Fig. 4. These plates are both laterally adjustable, and are secured to frame G by means of screws 6 e e e,

which pass through transverse slots through the plates at d, which when loosened can be moved to the right or left, as occasion requires.

' The forward ends of the plow-beams can be also moved laterally and secured at any desired point'to their respective bars a a, a number of holes being made in said bars to admit sot such adjustments.

The upper ends of the laterally-adjustable plates or bars or guides d d have bearings ff for two levers, J J, which are formed with hooks on their short arms, and to the extremities of these hooks rods J J are pivoted, as

shown at t i. The lower ends of the rods J J are pivoted to the plow-beams. vers J J are thrown forward, as shown in Figs.

When the le- 1 and 3, so that their long arms rest upon the foot-stand K, the points i i will be moved forward of the pointsff or fulcra of the levers, and the beamsF F will besustained positively in an elevated position,as shown in Figs. 1 and 4. When thelong arms of levers J J are moved backwardand the points i t pass back of vertieal planeiintersecting the fulcra of the levers the beams FjF will descend and assume the position shown in Fig. 2. Either one or both plow beams may be raised or depressed at pleasure, and this can be done by the driver 'while sitting upon his seat. levers J J upon the adjustable slotted guides By sustaining the d dit will be seen that the plow-beams can be adjusted, as above described, without interfering with the proper working of the levers.

this sector g, and when the beam L is in aline with the beam A the frame of the machine will be leveled for running over level surfaces, as shown inFigA; but when this beam Lis adjusted as shown in Fig. 2 the machine is ready for plowing. The wheel 0 being applied to a standard, 0, which is pivoted to the beam L, as shown in the drawings, it will be seen that it forms a caster-wheel and admits of the machine being turned short around with verylittle difficulty. It will also be seen,byreference to the drawings, Figs. 1, 2, and 3, that the landwheel 0 is located in a position opposite to the forward plow and some distance in rearofthe furrow-wheel. The latter wheel is arranged in front of the forward plow, and is intended to run in the furrow made in the previous round, while the former or land wheel is intended to run on the unplowed ground. By arranging these wheels B and (l as above described the depth which it is desired to run the plows can be regulated and the plows prevented from rising out of the ground in consequence of the wheel 0 passing over corn furrowed land, or land which is otherwise very uneven.

Having thus described our invention, what we claimas new, and desire to secure by Letters Patent, is 1 1. While not claiming a caster-wheel for the purpose of adjusting the plow, we do claim the arrangement of the hinged adjustable beam L with a caster-wheel, G, in the manner and for the purpose herein described.

2. The use of self-locking levers J J for raising or depressing the plows, applied to the adjustable guides d 61, substantially as described. 3. Connecting the hooked locking-levers J J to the plow-beams by means of bent swinging rods, substantially as described.

4. The laterally-adjustable slotted plates d 61, applied to the slotted frame G, and adapted to serve as "guides for the plow-beams F F, and also .as bearings forlevers which are used to raise and depress said beams, substantially as described.

5. Pivoting the forward ends of the plowbeams to rocking bars a a, which are arranged one in advance of the other, and applying the plows to said beams at about equal distances from their respective pivotal connections, substantially as described.
