SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 230,497, dated July 27, 1880.

Application filed February 10, 1880.

To all whom it may concern:

Be it known that I, HORACE E. REEvEs, of Fort Dodge, in the county of Webster and State of Iowa, have invented a new and useful Improvement in Sulky-Plows, of which the following is a specification.

Figure 1 is a perspective view of the improvement. Fig. 2 is a sectional side elevation. Fig. 3 is a plan view of the weed-layer.

The object of this invention is to construct sulky-plows in such amanner that the plows can be readily adjusted and controlled, will be firmly held while at work, and will yield should they strike an obstruction.

Similar letters of reference indicate corresponding parts.

A represents the Wheels, the crank-axles B of which are pivoted in collars or bearings 0 attached to or formed upon the ends ofthe axleshaft 1), the one above and the other below the ends of the said axle-shaft.

To the inner or pivoted arms of the crankaxles B are rigidly attached the lower ends of the levers E, which move along the outer sides of the arched bars or plates F, attached to the upper sides of the ends of the axle-shaft D.

The crank-axle B of the furrow-wheel should project forward to keep the furrow-wheel out of the way of the furrow-slice, and the crankaxle B of the landside-wheel should project to the rearward to take the side draft off the landside of the plow.

The hubs 1 of the wheels Ahave flanges 2 around their ends, to which the inner ends of the spokes 3 are attached alternately. The outer ends ot'the spokes 3 areinserted in tapering or countersunk holes in the iron bands 4 that form the rims of the wheels A. With this construction no separate tire or fellies are required, the band 4 serving for both, and the spreading of the spokes 3 toward their inner ends braces the wheel and makes it very firm, strong, and durable.

The axle-shaft D is made square,and in its middle part, a little at one side of its center, and in such a position as to bring the plow to the required distance from the furrow-wheel, a part of the said axle-shaft D is turned down or otherwise formed into cylindrical shape to receive the bearing or clamp L, which is made in two parts, the ends of which 'project and are securedv to each other by staple-boltsM.

The rear partof the beam N is curved downward, and has an ordinary plow, O, attached to it in the usual way. The plow-beam N has a shoulder, P, formed upon it for the forward end of the bearin gs L to rest against to take the draft-strain, and thus relieve the bolts M from the said strain. To the plow-beam N, a little in front of the shoulderl, is secured, by a clamp, Q, the rotary cutter S.

Theforward end ot'the plow-beam N is curved upward, and to it is pivoted the lower end of a bar, T, the upper end of which is pivoted to the lever U. The lower end of the lever U is pivoted to lugs or other support formed upon or attached to the upper part of the bearings L, so that the bearings L and the plow N 0 may be turned together to raise and lower the said plow N O, as required.

To the axle-shaft D, at the landside side of the bearings L, is bolted the bend of abar, V, the arms of which project forward. The upper arm of the bar V is made the longer, and at a .point directly over the end of the lowerarm is bent inward at right angles, and its end is bolted to the wooden beam or bar W. The rear end of the bar W rests upon the axle-shaft D, and is secured to it by bolts, which bolts also secure the rear end of the bar X. The bar X projects forward, and its forward end and the forward end of the lower arm of the bar V are bolted to the arms of the bar Y a little above its angles. One end of the bar Y is bolted to the upper arm of the bar V near its forward angle. The other end of the bar Y is bolted to the bar W. In the horizontal middle part of the bar Y are formed a number of holes to receive the bolt of the clevis Z, to which the draft is applied, so that the point of draft attachment may be adjusted to adjust the plow to take or leave land, as may be required. The bars V WV X Y thus form a firm, strong, and rigid frame for connecting the draft with the axle-shaft D, and thence with the plow NO.

To the rear parts of the bars V W are attached the ends of a standard, a, to the upper side of the bend of which is attached the standard b of the drivers seat 0.

To the lower side of the bend of the standard a is attached the upper end of the bracebar (I, the lower end of which is attached to the upper arm of the bar V midway between its forward angle and the bar W.

In the side edge of the lower part of the bar d is formed a notch, e, to receive the lever U when the plow is raised from the ground, to hold the said plow suspended for convenience in passing from place to place.

Upon the upper part of the brace-bar dis placed a small catch-plate, f, which is slotted longitudinally to receive the bolt or rivet g, by which it is secured to the said bar 01.

In the outer edge of the plate f is formed a notch, h, to receive and hold the leverU when the plow N 0 is in a working position.

i is a small wooden pin, which is passed through holes in the catch-platefand in the bar d, to hold the lever in place against the strain from the plow.

The pin '23 is made of such a size as to sustain the strain under ordinary circumstances, but which, should the plow strike an obstruction, will break and allow the plow to swing back to prevent the said plow or the machine from being broken.

The forward end of the catch-platefis beveled and rests against a pin, j, attached to the bar d, so that should the pin t break the pinj may turn the said catch-platef to release the lever U.

To the forward part of the bar W is attached a plate, k, which is made wider than the said bar XV, and is slotted transversely to receive the bolt l, and is grooved transversely upon its lower side to receive the head of the bolt 1 and prevent it from turning. The bolt 1 passes up through a hole in the rear end of the tongue m, and has a nut screwed upon its upper end. With this construction, by loosening the nut of the bolt l the tongue m may be adjusted laterally as may be required.

a is abar or strap which passes around the axle-shaft D in front of the mold-board. of the plow O, and is clamped to the said axle-shaft by a bolt, 0. The lower arm of the strap a projects to the rearward, and to it is attached the forward end of a rod, 17, which is curved outward in front of the mold-board of the plow 0 into such aposition as to bend down tall weeds and grass in front of the plow, so that the said weeds and grass will be covered by the furrowsliee as it is turned into the furrowpreviously formed.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a sulky-plow, the combination, with the plow-beam N, having its forward end bent upward, and the bearings L, of the connecting-bar T and the lever U, pivoted upon said bearing, substantially as herein shown and described, whereby these parts all rock upon the axle, as specified.

2. In a sulky-plow, the combination, with the lever U and inclined bar d, of the slotted and notched plate f, having its forward end beveled, the wooden pin 11, and the stop-pin substantially as herein shown and described, whereby the plow is allowed to swing back should it strike an obstruction, as set forth.

HORACE E. REEVES.
