PATENT rtree@ OVATVVOOD, OF LEBANON, ILLINOIS.

IMPROVEMENT IN GANG-FLOWS.

Specification forming part of Letters Patent No. 54,089, dated April 24, 1866.

To all whom it may concer/n:

Be it known that I, OARRELL ATWooD, of Lebanon, in the county of St. Clair and State of Illinois, have invented a new and useful Improvement in Gang-Flows; and I do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 of the accompanying drawings is a plan of one of the improved plows. Fig. 2 is a rear-end elevation of the same. Fig. 3 is a sectional elevationl taken on the line a b in Figs. l and 2. l

This invention relates, first, to the connection between the `forward end of the supporting-frame and the plow-beams; secondly, to the adjustable connection between the metallic head plate on the front of supportingframe and the ends of the aXle, whereby the whole machine may be adjusted to a correct alignment; thirdly, to a combination of levers and brakes for the purpose of keeping the plows in the ground while at work; fourthly, to the adjustable clamp on the rear ends of the plow-beams for the purpose of adjusting the plows by means of a movable brace, so as to throw the points of the plows more or less down.

To enable those skilled in the art to make and use my gang-plows, I will proceed to describe their construction and operation.

The axle A, the wheels A', (not shown in model,) and the supporting-frame A2 are of the usual construction in common use, and consequently will not be minutely described here.

The guiding-frame for the plow-beams, composed of the metallic stands B B and the beam B', the adj ustability of these parts to different widths, and their connection with the axle are the same in detail as the similar parts in a patent already allowed to myself. Consequently they will not be described here or alluded to any further than they are connected with the parts especially incorporated in the present invention.

C is a metal plate, placed on top of the forward ends of the beams of the frame A2 and fastened to them by means of the bolt a and beam-sockets a2. Slots a are made in the plate C for the passage of the fastening devices a and a2, which, after passing through the plate C and frame A2, are secured in position by meahs of the nuts a3 on the bottom of the frame A2. By loosening these nuts the slot a will admit of any desired regulation ot' the width of the frame, after which it may be again iirmly secured by tightening up the nuts a3.

On either sideof the machine there is a brace or tiered, D, the forward end ot' which is firmly secured to the plate C, while its back end passesv through an eyebolt or other similar device attached to the axle, and is there secured by the nut b.

After the machine has been set up it may be correctly aligned by loosening one of the nuts b and tightening the other, and vice versa.

A shaft, E, has its bearings in the lower ends ot' the -stands B, between which points of support it is provided with a short lever, E', the outer end of which is arranged to hook onto a series of hooks on the lower end of the hook-rod F, which is suspended under the cross-bar Gr, to which it is securely attached by means of connecting-links. n

The bar G rests on top of the plow-beams H. rI he drivers seat (not shown) should be located on the outer end of the beam B' at s, from which position he can easily place his foot on the lever E2, the lower end of which is irmly attached to the shaft E. By pressing down the lever E2 the driver can transmit, through the medium oi' the shaft E, lever E', and rod F, any required amount of pressure to the bar G, and thus hold the beams H down, so as to keep the plows H in the ground.

These devices are intended to overcome a difculty experienced by farmers in keeping the plows in the ground in some kinds of soil, especially hard or stony ground.

The plow-post H2 is fastened to its beam by a single bolt, d, so that the lower end of it may swing backward or forward, as may be required to accommodate the length of the brace H3, which is fastened to the post by means of the bolt d', which admits a like lonA gitudinal motion. The upper end of the brace H3 passes through a strap-piece, c, attached to the rear end of the beam H, and is then se cured by means ot' the setscrew c. The brace H may be adjust-ed so as to place the plow more or less forward, thereby throwing the point of it more or less elevated, and then the parts thus adjusted secured in position .by

tightening the set-screw c'.

Having described my invention, vWhat I vclaim is- 3. The combination of the shaft E, levers Eand E2,`hookr0d F, and cross-bar Gr, or their equivalent devices, with the plow-beams of gang-plows, for the purpose herein set forth.

4L. The combination of the strap-piece c and set-screw c with the beam H and with the braces H3, as and yfor the `purpose set forth.
