PATENT SAMUEL XV. BARR, OF. MANSFIELD, OHIO.

SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 298,337, dated May 13, 1884.

Application filed January 3, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL W. BARR, of Mansfield, in the county of Richland and State of Ohio, have invented new and useful Improvements in Sulky-Plows, which are fully set forth and described in the following specifications and accompanying drawings.

My improvements consist in a plow constructed to admit a wheel between the standard and landside, and in a combination of devices for raising the point of the plow through the medium of a vertical hinge at the end of the plow-beam, and in a horizontal hinge at the rear end of the tongue, connecting it with the plow-beam.

Figure l is a side view of my sulkyplow, with the rear portion of the mold-board cut away to show the relative positions of the standard, small wheel, and landside. Fig. 2 represents a portion of the front end of the plow-beam and the rear end of the tongue connected by the hinges, the upper half being cut away to show the mechanism of the center. Fig. 3 is a vertical section of the hinges with the connections.

Similar letters refer to similar parts.

The standard of my plow is formed with a broad base extending down under the moldboard and share, and a portion of it projects back along the landside F, to which the front end is bolted. The standard is set near the center of the plow, or about four inches from the landside F, leaving a space for the small wheel H. A shank, E,with a spindle riveted to its lower end for the wheel H, is bolted to the standard. The spindle extends to the landside as a brace, and has its center drilled out. A hole is drilled through the landside F in range with that of the spindle, and a bolt is placed in, as at G, Fig. 1. This bolt holds the rear end of the landside to the plow. The wheel H sets with its front close to the moldboard V, and lower than the landside, so as to completely carry the plow. The obj eot of constructing a standard to admit a wheel be tween it and the landside is to keep the plow short to facilitate turning at corners without running the plow out and backing to take the furrow. The standard D is secured to beam A by two bolts, one through the front head and one through the rear head and beam. A slot in the rear head allows the plow to be adjusted to width of furrow. Asegment-plate, L, with two studs on the opposite side,to prevent turning, is secured to the beam by the same bolt that holds the lever M. The lever M is formed with a disk at its lower end, and is provided with the usual devices for engaging the segment L. A stud near its fulcrum takes the end of the rod J. The other end of the rod is connected with the lower end of the curved bar 0 by bolt.

Fig. 3 represents avertical section of a cast block, Y. This block is hollow, and has two projecting flanges or sides, between which the rear end of the tongue. B moves, and a lateral projection or side, as shown at Y, Fig. 2, which laps the side of the front end of the plowbeam A. The block Y is the intervening head or base of the, vertical and horizontal hinges. The curved bar 0, Fig. 1, forms one of the projecting sides of the block Y, and is rigidly secured to it by two jutting flanges from the block over the edges of the bar, and by the eyebolt P, Fig. 2. The curved bar 0 and lateral projection, Fig. 2, form the vertical hinge at the end of the plow-beam A. The bolt W is the pivotal point. This hinge allows a vertical motion of the end of the plow-beam, and when the lever M is drawn back the lower end of 8c projecting sides, and the end of the tongue B iscovered with an angular cap that fits the socket. The cap has two projecting sides, that extend forward, and cover the top and bottom of the tongue, as shown at B, Fig. 1. The two sides have elongated holes running in line with the tongue, through which the bolt B, Fig. 1, passes, while the holes through the projecting sides of the block Y are round for the same bolt. A hole is bored into the end of the tongue, and a spiral springis placed in, as shown at S, Fig. 2. The spring is longer than the hole, and is compressed against the bolt B, when the cap is put over the end of the tongue.

IOO

The spring pressing against the bolt R and the cap keeps the end of the tongue in the socket of the block Y, and in backing the plow the tongue B and beam A are held firmlyin line; but when turning at corners, the spring is compressed and the tongue is forced forward to get out of its socket and pivots 011 the bolt R.

N, Fig. 1, is a post, with its lower end bent into crank form for the caster wheel, and held to the block by the eyebolt P. On the shaft or vpost below the beam a short arm is swiveled and held to place by the set-screw on. An eyebolt, O, at the outer end of the arm, holds the draft-rod I. The rod I can be ad- I5 justed by this arm for two or three horses.

spindle or bolt passing through the axle and secured at one end to thelandside, and at the other end to a vertical arm depending from the standard, said spindle serving as a journal for the wheel, and a brace or spreader between the landside and standard, substantially as shown and described.

2. The combination, with the beam A and tongue B, of the curved bar 0, forming one side of the vertical hinge between the beam and tongue, block Y, pivot-bolt W, and lever connection J M, substantially as shown and described.

3. The combination, with the tongue and plow-beam, of the block Y, socket Q, spring S, bolt R, and hinge-plates, substantially as described, and for the purpose set forth.
