IMPROVEMENT IN. GANG-FLOWS.

Specification forming vpart of Letters Patent No. 41,449, dated February 2,1864.

To all whom it may concern:

Be it known thatLMARsHALL SATTLEY, of Taylorsville, in the county of Christian, State of Illinois, have invented certain new and useful ImprovementsinGang-Plows 5 and Ido here by declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a rear view cfa gang-plow illus- Fig. 2 is a vertical longitudinal section at x ,Fig. l, looking toward the left. Fig. 3 is a section in the same plane, looking toward the right. Fig. 4 is a vertical longitudinal section thereof at y y, Fig. l. Fig. Fig.5 is a plan of aportion of the frame, illustrating the mode of adjusting the tongue. Fig. 6 is a side elevation of a device for securing and adjusting the wheels. Fig.7 is avertical section thereof at e z, Fig. 6. Fig. 8 is a plan of the same.

Similar letters of reference indicate corresponding parts in the several views.

The subject of myinvention is an implement having two or'more plows mountedina single beam extended in width for this purpose and adapted to lbe raised or lowered at will by a crank and lever, or their equivalents.

The invention further consistsin certain devices for bracing the plows longitudinally and laterally and adjustingtheir pitch or inclination, a device for securing the tongue at any angle horizontally, and a device for setting the frame up or down on the wheels.

In order that others .skilled in the art to which my invention apporta-ins may be enabled to fully understand and use the same, I will proceed to describe its construction and operation.

A represents the main frame of the implement, attached to an axle, B, which is provided at each end with a flange, C C, sliding in dovetailed plates D D, the edges d of which clasp the iianges G of the axle, in manner clearly shown in Fig. 8, so as to prevent mo` tion in any but a vertical direction.

Fromthe plates D project stud-shafts E E,

y upon which the conveying-wheels'F F are mounted. The adjustment of the axle up or down may be effected either by hand-screws G Gr, swiveled at their lower ends to the axle and threaded above in horizontal lugs H H, pro jecting inward from the plates D,or it may be 'secured in any desired position by means of keys I, passed through elongated perforations in the plates C and D, and turned to keep them from coming out. v

K represents a beam formed of a flat plank of sufficient width to carry two plows, L L, the standards M M of which may occupy suitable mortises or be bolted directly to the edges of the beam, and are provided with lateral braces N N, projecting inwardly and secured in mortises near the center of the beam.

O O arelongitudinal braces, attached at their lower ends to the standards M, and projecting forward and upward therefrom to the sides of the beam,when they are held by set-screws P, which occupy vertical slots in the braces, so that the plows may be set on any desired angle or pitch'.

B R represent draft-chains, attached at their rear ends to the braces O or standards M, and at their front ends to hooks fr r on the axle B, in such position that4 they will be slack in the elevated position ot' the beam and plows, but will be drawn tight by lowering the plows to their working position.

The elevation of the beam to raise the plows out of the ground and adapt the implement to be transported from plane to plane is eected by a crank, S, journaled to the under side ot' the beam. This crank is turned by means of a lever, T, having a motion of about ninety degrees within a loop, u, and held in any position by means of a segment-rack or perforated plate, U, in order to secure the plows at any desired elevation. The horizontality of the beamv at all heights is preserved by'means of jointed rods V, by which its forward end is connected to the axle B. A crank may be substituted for these rods, if preferred; or pointed rods may take the place of the crank already described.

The tongueW is attached to the front of the frame by two bolts, w w, one of which, when its nut is loosened for this purpose,works in a slot in the frame, so as to permit the tongue to be adjusted laterally in either direction, when it may be again secured by turning down the nut.

f X represents the drivers seat.

Having thus described myinvcntiomwhatl bly to the axle B, and adapted to be drawn claim as new therein, and desire to secure by Atight-by lowering the plows to their Working Letters Patent, is position.
