IMPROVEMENT IN GANG-PLOWS.

Speeitication forming part of Letters Patent No. 20,342, dated May 25, 1858; antedated March 18, 1858.

To all whom it may concern:

Be it known that I, JEssE FRYE, of Mendota, in the county ot' La Salle and State of Illinois, have invented certain new and useful Improvements in Gang-Flows, and I do hereby declare that the following is a full, clear, and exact description ot' the construction and operation ofthe Same, reference being had to the accompanying drawings, in which-- Figure l represents a perspective view of said gang-plow. Fig. 2 represents a perspective view ofthe same represented from the rear side of Fig. 1. Fig. 3 represents a top view of the plowstocks and their connections with the tongue, the frame-work heilig represented in red line.

The nature of my invention relates to that class of plows termed gang-plows,77 and by which a number of furrows are made and subsoiled at one operation; and it consists in the peculiar construction, hereinafter described, by which the positions ofthe plow-stocks and colters are made self-adjusting as the plow is turned.

To enable others skilled in the ait to make and use my invention, I will proceed to describe its construction and operation.

A represents two hed-pieces of the plowframe, to which the plow-stocks L are secured. To the top of these bed-pieces are secured the front and side pieces, B, which, together with the former A, constitute the frame of the plow,

and which serve to support the bearings of the vertical shai'ts D, on which the wheels are placed. C represents cross-ties, and E a transverse piece forming part of the frame, and secured to the plane so as to support the seat and other parts ot' the machine. The*` frame is supported by and moved on the three wheels F FZ F3, the horizontal axes of which are secured or connected to the vertical shafts D, which can slide within the sleeves or bearings G, and the top parts of which bear upon the lower sides of the levers H.

I representthree metal bars, which are pivoted to the frame at a, and to the upper parts of which the ends ofthe levers H are pivoted. The long arms of the levers H pass between the slotted standards K, and are held therein to any desired position by means of the pins b, which may be inserted into any of the holes c.

By operating one or all of these levers H one end or the entire plow-frame can be raised or lowered at pleasure.

L represents the plow-stocks to which the mold-boards are secured, which are made of one single piece of shear-steel, as described in the Letters Patent heretofore granted to me. The top parts of these stocks are dat and ot' the segmental form represented at M in Fig. 3. These pieces M are pivoted at d to one of the bed-pieces A, while their circular faces rest within corresponding grooves of the arcs N, which are secured to both of the hed-pieces A. Thus the stocks L can be turned on their pivots d and are guided in their movements by the ares N.

-To each of the stocks L, except to the rearmost one, is secured asubsoil-coher, O. The shank it of said colter passes through a sleevebox,f, formed on the plow-stock, and the colter is secured to any desired point or height by means of the set-screw g, the end of which reaches within a groove of the shank lt. Another arrangement for adjusting the colter consists in the sleeve t', which rests upon the boxf, and which can be secured to the shank It by tightening the set-screw g. The top plate, M, of the forward plow-stock is tted within the tongue-coupling J, so as to join both stiftly together and allow them both to turn together on pivot d. The tongue-coupling P and tongue Q are secured together by a bolt, l.

R represents a curved slotted arm, which is secured to the shaft of the front wheel, and is also secured to the tongue-coupling P by bolt l passing through slot m, so that when the tongue is turned on the pivot d the wheel F will turn with said tongue. 'A

S represents crank-arms, which are respectively attached to each of the wheel-shafts D. The positions ot' these arms are shown in the drawings. These arms are connected to each other by means ot the rods T. Thus when'the forward wheel, F', is turned in the same direction as the tongue the rear wheel,F3, is turned in the opposite direction by reason of the reversed positions of their respective arms S, and this is necessary to cause the rear wheel to track the forward wheels, both forward wheels being kept parallel by means of the parallel arms S on their respective shafts.

U represents a rod, Fig. 3which is pivoted to the pivot d of the rearmost plow-stock, and which is secured firmly to the frame by means of brace n, Fig. l. To the end of this rod the tongue Y is linked, at W, so that the draft of the team is exerted equally upon the foremost and rearmost p1ow-stocks. Both tines of the tongue are connected to each other by a pivoted brace, o. The top plate, M, of the rearmost plow-stock is fitted within a lever, X, in such a manner as to secure one stiftly to the other Iand so that both may be turned together on the pivot d. To this lever are pivoted, at r and s, the rods Y and Z, which are respectively linked to two other plow'stocks atp and q. The lever X and rods Y and Z are perforated by a number of holes, by means of which the lengths of their connections can be adj usted at pleasure, so that when the tongue is turned by the team the forward plow-stock is turned in the same direction with the team, it being stiffly secured to thetongue-stock P. This movement willcausethe rearmost plow-stock to be turned on its pivotd in an opposite direction to an extent which will depend upon the respective lengths of the lever-X and rod Z, and the points ofthe plows are turned so that the lines ot' their landsides shall converge toward one point.

Itis evident that the length ofthe rod Y can be adjusted so as to cause the second plow also to point toward the same center, and as the number of plows in my machine is not limited, so far as the principle of the same is concerned,

` it follows that any number can be connected by proportional levers and rods, as at x y z, which, when properly adjusted, will cause all the plows to point to one common center upon the plow being turned by the team. The effect of this will be that the plows can be turned with the greatest ease without raising them from the ground, because they are turned toward the center of the circle which is described by the machine, and consequently there will be no 'greater excess of side pressure of plows against -the earth when the plow is turned than when going straight. As above stated, the rearmost plow-stock is not provided with a subsoil-colter. This is for the purpose of allowing the rear furrow-wheel, F3, to run on the unbroken or smooth bottom of the furrow made by the rearinost plow. At the next opera-tion of the ga'ig the wheel F will run in the solid fur- Arow in which the wheel F3 ran at the lformer through/7 and then the colter t will subsoil said furrow. u represents the sleeve or bearing of this colter, and c is a brace, which eX- tends from said stock, and the stock and base are hinged to the frame at zr. The stock u is hung at its lower end to a ehaimx, which passes over a pulley, y, and which chain is fastened to a hook on the pivot z on the tongue Q. a represents a. clevis in chain x, which may be inserted at any desired point, and by which the colter t is prevented from entering the soil beyond a certain depth.

When the plow is running in a straight line the colter tsubsoils the last furrow made at a previous operation after the wheel F has passed and before the mold-board of the first plow turns said furrow; but when the plow iS turned the colter t is raised, so as not to be in the way of the mold-board otI the first plow.

This plow is arranged to be worked by three or more horses, hitched respectively to the tongues, one being between the tines thereof. b represents the neck-yokes for the outside horses, and d a ring, to which an additional team may he hitched, it' required.

Having thus fully described the nature of my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The attachment of the tongues to the forward and rearward plow-stocks and the connections between the various plow-stocks, so that when the team is turned the plow shall be turned so as to point toward a common center, substantially in the manner and for the purpose described.

2. The connection ot' the forward furrowwheel with the tongue by means ofthe curved slotted arm R and bolt l, in combination with the cranks and connecting-rods between the wheel-shafts, so that when the team is turned theforward wheels shall be turned in the same direction ,and the rear furrow-wheel shall be made to track the forward wheels', substantially in the manner and for the purpose set l'orth.

3. Hanging the rigid colter t to the rear of the front furrow-wheel by means of a chain, which, when the team is turned, will raise said colter out of the furrow, substantially in the manner and for the purpose set forth.

JESSE FRYE.
