SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 361,830, dated April 6 887- Application filed December 20, 1886. Serial No. 222,084. (No model.)

To all zohom it may concern:-

Be it known that we, JosEPH MARX and ADRIAN VIRNIG, both of Cross Plains, in the county of Dane and State of \Visconsin, have invented a new and Improved Sulky-Plow, of

iently guiding the machine and for regulating the operation of the plows, the colter, and the draft-tongue for working'to any desired depth in the soil.

The invention consists in certain novel features of construction and combinations of parts of the sulky-plow, all as hereinafter fully described and claimed.

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

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of our improved sulky-plow with the righthand plow lowered and the left-hand plow raised and the drafttongue partly broken away. Fig. 2 is a planview of the plow. Fig. 3 is a rear view thereof. Fig. 4 is a bottom plan View of the plow. Fig. 5 is a vertical transverse section taken on the line 00 m, Fig. 1; and Fig. 6 is a top plan iew of one of the plows detached.

The sulky-frame A is made with three longitudinally-ranging timbersa center one, a, and two sides,-a co -which are held at proper distances apart by upper and lower cross-bars,

a a, near their forward ends, and by upright posts 1 2 3, which are fixed to and rise from the rear ends of the timbers a acfi, respectively, and are framed at their tops to a crossbar, a a lower cross-bar, a, being bolted to the timbers a little distance behind'the axle B,which is pivoted to the center frame-timber, a, on a kingbolt, C, so that the wheels D D, journaled on the axle, mayswing therewith in guiding the machine when at work. Metal strap-frames b b, fixedto the under sides'of the frame-bars ver, G, which is pivoted at g to the frame-bar a, and carries a spring-pressed trip-latch,

adapted to engage a catch'plate, g, fixedt; (L

the frame.

It is obvious that by releasing the latch and swinging the lever G the sulky-wheels D may be swung to the right or left more or less, to guide the machine to secure a proper width of furrow cut by either or both of the plows connected at the back end of the machine, in a manner presently described.

Along bolt, H,is passed transversely through the forward ends of the frame-timbers a a a and through spacing-blocks h h, placed between the outer timbers, a. a and also through the rear forked end, i, of the sulky-tongue Lwhich straddles the end of the center frame-timber, a, and brace-rods J J, bolted at their forward ends to opposite sides of the tongue, are held pivotally upon the bolt H, to assure lateral stiffness of the tongue, to provide for easily turning the machine to either side, and at the same time allow free vertical play of thetongue on its pivot-bolt. A bar, K, is fixed at its for-- ward end to the top of the tongue I, and extends rearward over the frame A, and at its rear end has a handle, 70. This bar K, which serves as alever for adjusting the outer end of the tongue higher or lower, is braced about 'mid-way of its length from the tongue-pivot 60 F to the lower end of a vertically-ranging lelever has fixed to it a keeper, it, through which the bar M passes, tohold it in proper relation with the lever, to allow a spring-pressed latch, N, pivoted on the lever to be engaged with any one of a series of notches, m, made in the rear face of the bar M, which will swing on its pivot m as the rear end of the lever K is raised or lowered to lower or raise the forward end of the tongue.

It is obvious that by operating the lever K. the tongue may be adjusted up or down at any time, and locked to accommodate the size of the draft-animals, which are hitched to a double-tree, I, pivoted to the tongue, and also to regulate to some extent the depth at which the plows shall work in the ground.

, The plow-beams O l, to which the two plows R S, respectively, are attached, are pivoted on a heavy draft-bolt, T, passed transversely through the frame A near its forward end, spacing-block'stt being placed on the bolt between the sides of the plow-beams and the side timbers, a c of the frame, to hold the-beams flat'againstoppo'site sides of the'center timber, a, of the frame and prevent lateral play of the plow-beams, to the back ends of which are fixed upright blocks or standards 0 p, which stand between the rear frame-posts, 1 2 3, and give substantial lateral bracing to the rear .ends of the plow-beams and the plows.

The plows RS are right and left hand plows, respectively, and their branched or forked standards are bent 'at right angles at their tops, forming flanges which are slotted laterally to receive bolts r s, which fasten the plows to the under sides of their beams and allow the plows to be adjusted laterally, so that their adjacent landsides shall stand in proper relation to each other and to the disk or rolling colter U, held in advance of the plows, as presently described. The plows may have any ordinary or approved construction, but will preferably be made entirely of metal.

To suitable brackets orpins connected to g g tlre rear ends of the plow-beams O P are connected one end of chains 0 p, which pass over grooved margins or peripheries of semicircular plates 0 P, which are journaled on pins or shafts fixed in the uprights 2 3 and in inclined brace-bars 4.- 5, respectively fixed to these uprights and the side timbers, a c of the frame A, and the other ends of the chains 0'10 are attached to suitable hooks or pins fixed to the plates, and whereby as the plates are turned in one direction their attached plows will be raised, and when turned the other way the plows will belowered. Levers O P, fixed to the plates 0 1?, respectively, provide for turning the plates to raise or lower the plows, and the levers have spring-pressed latches 0" pfiwhich engage catch'plates 0 p on the framebars 4 5, for locking the plows at any required vertical adjustment. Metal keepers 6 6, fixed to the frame cross-bar a form guards to the chains 0 19, to hold them onto the vibratory plates 0 P.

As will be understood from Figs. 1 and 3 of the drawings, either of the plows R S may be lifted clear above the under side of the axle B, while the other plow is at work in throwing a furrow either to the right or left hand, or both the plows may be lowered at the same time for cutting a dead furrow for ditching or land-draining purposes. Furthermore, the flexible connections 0 12' between the plowbeams and the plates 0 I allow the plows to rise should they strike a stone or other ob and the lever V, to give the main or principal vertical adjustment to the colter for working approximately at the desired depth in the ground. The lever V is also slotted to receive a bar, 12, which is pivoted at its lower end 'to the frame-timber a, and is provided with a series of holes, 12, into any one of which a pin, o passed through the lever V may be placed. The bar 1; and pin 0 provide for close vertical adjustment of the colter after it shall have been set approximately by the pin if, as above described. 1

All of the levers G, K, 0 P, and V may be conveniently reached by the driver or attendant seated on a seat, W, supported above the sulky-axle preferably by two spring-plates, w w, fixed at one end to the seat, and at the other end to the uprights 2 3 of the frame, thereby allowing the machine to be guided, the tongue to be raised or lowered, and the plows and colter to be set at any required vertical adjustments without requiring the driver to leave his seat or in any way lose control of the team.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent 1. In a sulk'y,the combination, with a frame, as A, supporting two plows, and supported on wheels fitted to a centrally-pivoted axle,B, of a cross-bar, F, pivoted to the frame, rods E, connecting the ends of said bar to the ends of the axle, and a lever, G, fulcrumed to the frame and connected to .the bar F, substantially as described, for the purposes set forth.

2. In a sulky-plow, the combination, with the frame A,provided with the posts 1 2 3 on its rear part, of the plow-beams O P, pivoted to the forward part of the frame,'and provided with standards 0 p, projecting up between the posts 1 2 3 of the frame,substantiallyas herein shown and described.

3. In a sulky-plow, the combination, with the frame A,provided with the posts 1 2 3, and

brace-bars 4 5 on its rear part, of the plowbeams O P, pivoted to the forward part of the frame, and provided with standards 0 1), projecting between the posts 1, 2, and 3 of the frame,

5 the pivoted semicircular and grooved plates 0 P, chains 0' 1), connected to the plowbeams and semicircular plates, and means for operating and locking the plates, substantially as herein shown and described.
