IMPROVEMENT IN GANG-FLOWS.

Specification forming part of Letters Patent No. 48,6279, dated July 11, 1865.

To all whom t may concern Be it known that I, A. HAMMOND, of Jack sonville, in the county of Morgan and State of Illinois, have invented a new and Improved Gang and Trench Plow; and I do hereby de- Clare that the following is afull, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accom panyin gdrawings, forming part of this specitcatiom in which- Figure 1 is aside view of my invention, the arm of the wheel nearest the eye beingin section, as indicated by the line .fr Fig. 2; Fig. 2, a plan or top view of the same; Fig. 3, a 'transverse vertical section ofthe same, taken Vin the line w Fig. 2.

Similar letters of reference indicate corresponding parts.

This invention relates to anew andimproved gang or trench plow 5 and it consists in a novel construction and arrangement of parts, as hereinafter set i'orth, whereby the plows may be readily adjusted higher or lower, as may be desired, and also readily raised tomporairily out ofthe ground when necessary-as, for instance, in turning at the end of a furrow or field.

A A represent two parallel beams, which j are rmly secured to an axle, B, havinga wheel,

f end, to catch into a rack, F, on D and hold it in position. l

G is the drivers seat, the supports of which are attached to the beams A A; and H are plows, which are secured to the beams in any proper' manner.

The arms e ofthe wheels C are attached to slides I, which have racks f at their back or rear edges. These slides I are tit-ted in sockets J, which are secured on the ends of the axle, the slides being. allowed to slide freely up and down in the sockets. Each slide I has a screw, K, gearing into it, and these screws are provided with cranks L at their upper end for the purpose of turning them, the axes of the screws having their bearings attached to the sockets J.

It will be seen from the above description that the beams, and consequently the plows, may be raised andr lowered by turning the screws K, and the plows regulated or adjusted so as tp plow furrows of a uniform or equal depth, and the plows may be very quickly adjusted, a very few turns of the screws being sufficient for the purpose, and it maybe done while the plow is in motion or at work.

flo the plank or timber D there is attached a segment-rack, L,into which a pawl,M, catches, the latter being fitted in an upright, N, attached to one of the beams A. The pawlMis connected by a link, g, with a foot-lever, O, 4which has a spring, h, bearing against its under side, the spring having a tendency to keep the pawl M in contact with the rack L, as will be fully understood by referring to Fig. 3. By this arrangement the "driver at any time, by stepping on the rear of the plank or timber D, will cause the rear of the beams A A to be tilted up and the plows to be raised out of the ground, the pawl M and rack L preventing the beams and plows from descending. The plows may be let down at any time by depressing the lever O with the foot.

More or less land may be given the plows by adjusting the draft-pole E, as will be fully understood by referring to Fig. 2.

On the plank orl timber D there is abutton, P, which, when tn rned by the foot so as to Vproject over one ofthe beams A, will prevent the plows from being tilted up or raised out of the ground, and admit of the driver stand- .ing on said plank or timber in case he prefers I standing to sitting. l

The plows may be arranged so as to subsoil, trench, 'or turn regular furrows for tillage. In moving the machine from place to place the plows are elevated above the surface of the ground through the medium of the screws, the

tilting ofthe beams being adopted only for temporary elevations, as in turning at the ends of the furrows, 85e.

I claim as new and desire to Secure by Let-- ters Patent- 1. The segment-rack L, pawl M, und footlever O, all arranged and applied to the plank or timber l) and beam A, substantially as l(tud for the purpose specified.

2. The button P, when applied to the plank or timber D and used .in connection with the rack L, pwl M, and foot-lever O, for the purpose set forih.

A. HAMMOND.
