SULKY-IPLOW.

SPECIFICATION forming para of Letters Patent No. 292,304, dated January" 22, 1864. Application led October 22, 1883. I (No model.)

4and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in

which similarlettersof reference indicate cor# responding parts in all the figures.

Figure l, Sheet 1, is a plan view of my improved sulky-plow.- Fig. 2, Sheet 2, is aside elevation of the same, the land-wheel bei-ng removed. Fig. 3, Sheet 2, is a front elevation of the same, the tongue being shown in section, and part being broken away.

The object of this invention is to improve the construction of the sulky-plows for which Letters Patent Nos. 218,734, 232,268, 255,97 7 and 264,692 were granted tome, respectively, August 19, 1879, September 14, 1880, April 4, 1882, and September 19, 1882, in such a manner as to adapt the plows to turn asquare corner in passing around a land .without vits being necessary to raise the said plows out of the ground. v

The invention consists in asulliyfplow constructed with the movable part of its tongue connected by a lever and an eyebolt with the A crank-arm of the rod carrying the'crank-axle of the furrow-wheel,whereby the lateral movement of the said movable part of the tongue will turn the said wheel. laterally, and adapt the machine to turn the corner of aland without having the plow taken out of the ground,

as will be hereinafter fully described andl claimed.

A is a cross-bar, to the lower side of the .middle part of which is attached the middle part of the axle B. The end parts of the axle B are bent downward at right angles,andthen outward at right angles, to bring their ends below and -at a suitable distance from the ends of the cross-bar A. Gis the land-wheel, the crank-axle D of which is attached to thelower end of a rod, E. The rod E passes up through the end of the cross-loar A, and is kept from dropping away from the said cross-bar by a pin passed through the upper end of the said rod, or by other suitable means. ward movement of the rod E through the l cross-bar A is limited by the block F, through which the said rod passes, and which slides in `a slotted or U-shaped hanger, G, attached to the'cross-bar A near its end, and to the end down through a screw-hole in the cross-bar A and rests against the upper side of the said block F, so thatthe height of the landside end .of the axle B.' The upward movement of the Y Vsliding block F within the hanger G is regulated by the crank-screw H, 'which passes ofthe cross-bar A, and consequently the depth To the lever J is attached the cnd of a short chain, J', the other end of which is provided with a ring or large link, to be passed over the hook J2, attached to the crossbar A, to lock the lever J and crank-bar I in place, and thus hold the plow in the ground. The, lever J is provided with an arm, K, to serve as a footrest, so that the plowman can raise and lower the plow. with his feet. The forward end of the plow-beam passes through the slotted or U-shaped hanger L, theupper end of which is bolted to the cross-bar M. The cross-bar M is slotted longitudinally to receive the fastening-bolt, so that the Vforward end of the plow-beam can be adjusted laterally, to cause the plow to cut a wider or a narrower furrow.

To the hanger L is pivoted a crank-foot lever, N, to rest upon the forward end of the plow-beam, so that the driver can operate the said lever with his foot, to hold the said forward end of the plow-beam down, toycause the plow to enter the ground, and' to hold it in the ground in plowing hard soil. The landside end of the cross-bar M is attached to the lower end of the bar O, the upper end of which is attached to the cross-bar A. The other end of the cross-bar M is attached to the lower end of the bar l?, the upper end of which is I AOO attached tothe rear or stationary part Q of the tongue. The cross-bar M is further secured in place by being attached atits ends t0 the braces R, the rear ends of which are attaclied to the upright parts of the axle B, near their lower ends. lThe forward ends of the braces R are attached to the stationary part Q of the tongue near the forward end of the said part. rlfhe stationary part Q, of the tongue is bolted or clamped at or near its rear end to the erossbar A.

S is the movable part of the tongue, which is pivoted to the stationary part Q, by a bolt, T, passing through the said parts Q, S. The two parts Q S of the tongue can be secured to each other by two or more bolts when a stiff tongue is required.

To the stationary part Q of the tongue, in front and rear of the pivoting-bolt T, are attached bars U, having upwardly-projecting ends, the said stop-bars being so arranged that the movable part S of the tongue cannot be swung to the right beyond the vertical plane of the said stationary part Q, but can be swung to the left through an angle of fortyfive degrees, more or less.

V is the furrow-wheel, the erankaXIe 'W of which is placed beneath the end of the axle B, and is attached to the lower end ofthe rod X. The rod X passes up through holes in the ends ofthe axle B and cross-bar A, and has a forwardly-projecting crank-arm, Y, formed upon or attached to its end.

To the crank-arm Y is secured the rear end of a lever, Z, by a bolt, a., and a bolt or setserew, Z). rIhe bolt a passes through holes in the rear end of thelever Z, and in the crankarm Y, several holes being formed in the said crank-arm to receive the said bolt a, so that the lever Z can be adjusted forward or back, as may be desired. The set-screw b passes through a keeper, C, formed upon the end of the crank-arnr Y, and rests against the lever Z, so as to clamp the said lever against the said crank-arm. If desired, the keeper c can be omitted and a cross-slot formed in the end of the crank-arm Y, to receive the screw or bolt b, to secure the lever Z in place. Vith this construction, by loosening the screw or bolt b, the crank-arm Y can be adjusted to set the forward part ofthe wheel Y in or out,and cause the plow to take or leave land, and thus cut a wider or narrower furrow. The for- The crank-axle D of the land-wheel C is placed in the rear of the endof the axle B, and the crank-axle W of the furrow-wheel Y is placed in front of the end of the said axle B, so that the said wheels can be conveniently turned laterally in the proper directions. vVith this construction, when the team is turned at the corner of the land the movable part S of the tongue takes the position shown in dotted lines in Fig. l, and operates the lever Z and the crank-arm Y, 4to cause the furrow-wheel Y to take the position shown also in dotted lines in Fig. 1. As the team continues to turn, the furrow-wheel V rolls around the corner of the land into the eross furrow at the same time the rear part of the land-wheel C swings outward, and the said wheel rolls to the rearward, the machine turning upon the plow as a pivot. Then, as the team moves forward in a straight line the various parts of the machine take their normal positions, and the plow moves on in the new direction without having `been taken out of the ground.

I am aware that it is not broadly new to journal a wheel upon a swiveled post with a crank-arm upon the swivcled post connected to the tongue, so that the movement of the tongue will govern the course of the wheel.

Having thus described my invention, what I claim as new, and desire to secure .by Let-ters Patent, 'is- .1.. A sulky-plow constructed with the movable part- S ofthe tongue connected with the furrow-wheel by a lever, Z, adjustably se cured to a crank-arm, Y, which is attached to or forms part of the swiveled rod X, in combination with the furrow-wheel Y, directly opera-ted by said rod X, substantially as set forth.

2. Ina sulky-plow, the combination, with the movable part S of the tongue, and the crank-arm Y of the rod carrying the crankaxle of the furrow-wheel, of the lever Zand the eyebolt d, substantially as herein shown and described, whereby the lateral movement of the said movable part of the tongue is made to turn the said furrow-wheel laterally, fas set forth.

3. The movable portion S of the tongue, in combination with the stop-bars U, attached to the stationary part Q of t-he tongue, whereby lateral movement of the part S is prevented in one direction and limited in the opposite direction, substantially as set forth.
