SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 295,613, dated March 25, 1884.

Application filed August 11, 1883. (No model.)

To ctZZ whom it may concern:

Be it known that I, SAMUEL W. BARR, of Mansfield, Richland county, Ohio, have invented a new and useful Improvement inSulky- 5 Plows, which improvment is fully set forth in the following specification, reference being had to the accompanying drawings.

My invention relates to that form of sulky' or riding plow in which the plow is constructed to conform to the attachments and the attachments combined with the plow in such a way as to form a complete machine. Neither can be separated without leaving the other valueless.

1 5 My invention consists, mainly, in a combination of levers for raising the point of the plow by means of a vertical hinge at the front end of the plow-beam, and in a horizontal hinge at the end of the beam to allow the team to turn easily at corners and pull the plowaround also, in a combination draft-rod for gaging the depth of a plow.

Figure 1' is a side view of my sulky-plow, showing the combination draft-rod. Fig. 2 is a top view, showing the relative position of the wheel is, beam, and mold-board. Fig. 3 represents a portion of the beam and a por, tion of the tongue connected by the hinges, and is a view from the opposite side of the hinges of Fig. 1.

Similar letters refer to similar parts.

The beam A of my.plow sets nearly over the center, and is firmly bolted at its rear end to a cast base that holds the share and mold-board. The spindle of the wheel K, Fig. 2, is secured to a rear projection of this base, and the wheel runs on this'spindle with its face side against the 'bank of the furrow, and forms one side of the sulky, a portion of the landside, and carries the plow. The wheel is set with its front close to the mold-board, and hasasmall flange on the land-side edge of its rim to prevent slipping sidewise. Its diameter is such as to make the plow of usual length. The bracket P, Fig; 2, is permanently secured to the beam, and has one end drilled and bent down at right angles to its side, and the lower end is thrown out till its face is parallel with the outside of the segment Q. The lever g is formed with a disk at its fulcrum, and has a with its slot, is upon the short arm at nearly right angle, to the end of which the spindle for the wheel Z is riveted.

A bolt holds it to the bracket P, and when the plow is doing its work the lever 9 stands nearly perpendicular and the wheel Z is opposite the wheel K. The lever g is provided with thumb-lever, spring-pawl, &c., for engaging the segment. The lever F, Fig. ljis formed with a circular plate at its fulcrum, and a curved short arm, J, having a slot nearly its whole length. The lever is provided with the usual devices for adjusting it. The notched plate E has two points on the opposite side, that rest on the beam to keep it from turning, and is held to the beam by the same bolt that 6 holds the lever F. The short arm of the lever, cam principle, and when the lever is thrown forward the bolt of the bar B rides up the slot and lifts the bar. The bar B extends to the end of the beam, and forms one half of the hinge e, the other half of which is bolted to the end of the tongue D.

A bolt, W, through the end of the beam and bar B forms the vertical hinge at the endof the plow-beam. The bar B and tongue, connected by the hinge c, constitute a rigid line from the neck-yoke of the team to the lever F, and when the lever is thrown forward the end of the bar is raised, and the point of the plow also. In this operation the weight of the end of the beam, double-trees, &c., falls on the wheel K andneck-yoke.

Fig. 3 represents a portion of the beam A and the rear end of the tongue, and is a view from the opposite side of Fig. l. A top view of this arrangement is shown at m o a, Fig. 2. The hinge-bar m is secured to the side of the tongue by the same bolts that hold the front portion of the hinge c, Fig. 1. The strap a has a notch in its upper edge to catch in the 0 staple 0, and is knuckled with the bar m just in front of the hinge c. A spring, 15, knuckled with the bar at at the same point, slides through the staple. 0 below the strap N, and keeps the strap against the upper part of the staple. The 9 5 I staple 0 is strong and fastened firmly to the beam A, and is of such size as to give said strap the requisite play. This check-hinge holds the tongue and beam rigidly in line, but when turning at corners the strapN is pressed I00 U down by the drivers foot, disengaged, and the team can walk around and turn the plow while in the ground.

The side view of my sulky-plow, Fig. 1, shows a new form, of draft-rod for gagingthe depth of a plow. The rod S is bolted to the beam A above the mold-board, and has a thread out on its front end several inches back for a nut. A long clevis, H, with a hole in its end, is placed on the rod, and a spiral spring, I, of suitable strength and size, is put on between the sides of the clevis, and the nut turned on the rod. The clevis extends forward on either side of the curved beam projection R, and has. a bolt in the front end for a hitch. A small roller is placed between the sides of the long clevis to move along the lower edge of the projection R. A pin in the lower end of the deep, and the plow is thrown up by any obstruction, the spring will expand and draw the roller up the curved projection R, and turn the point of the plow down. On the other hand, if the plow cuts seven inches deep, more power will be required to draw the plow, the spring will be compressed, and the roller Having fairly and fully described the sev- 1 eral parts and functions of my sulky-plow, I wish to secure by Letters Patent the followmg:

1. The combination, in a sulky-plow, with the pivoted bar B, of the tongue D, the hingeplate 0, the hinged bars M N, staple O, and spring T, substantially as shown and described.

2. The plow-beam A, pivoted tothe bar 13, and the curved projection R, in combination with the spring draft-rod H, roller h, and draftclevis, substantially as set forth.

3. The combination, with the pivoted bar B, having 'pin 11, of the lever F, having the curved slotted arm J, the rack E, plow-beam A, and wheel K, substantially as shown and described.
