PLOW.

SPECIFICATION forming Vpart of Letters Patent No. 267,648, dated November 14, 1882.

Application filed August 31. 41882. (No model.)

To alt/whom it may concern:

Be it known that I, PEDRO A. FOMINAYA, a citizen of Havana, Cuba, have invented certain new and useful Improvements in Plows,

' 5 of which the following isaspecificationeferencebcing had therein to the accompanying drawings.

My invention relates to a wheel-plow for breaking up land. 1o I will tlrstdescribe the construction of the parts, their arrangement and connection with each other, their operation, and the advantages resulting therefrom, and will then designate the parts and combinations constituting the invention.

In the accompanying drawings, Figure l is a side view ot' the plow. Fig. 2 is a top view lof the plow. Fig. 3 is a rear end view.

y The letterA designates the beam; B, the cutzo ter; O, the mold-board; D, the landside.

The letterE designates a single wheel, which is in the rear and on-a line with the cutter. This wheel is intended to run 011 the bottom .of theA furrow, and serves when plowing as a steering-wheel, and when not plowing, but

when moving the plow, serves as a motorwheel on which the plow rides.

At the front end ofthe beam are two wheels, F, mounted on an axle, G, which has at its 3o center an upright bolt, H, passing loosely through the beam. This bolt may partly turn in its bearing ill the beam, and thereby the axle and wheels-F are so pivoted that they may be turned to change the direction of the moving plow. The bolt H and beam A have vertical movement with respect to each otherthat is, if the wheels be on the ground, the front end of beam has anl up-and-down movement by sliding ou the bolt, by which (as will 4o be presently explained) the plow may be lifted entirely from the ground.

`An upright post, I, is secured to the rear end of the beam, and to this post the landside D is bolted.

4 5 Two partly circular lor segment-shaped bars, J, are placed upright and alongside ot' each other, with a space between. One end of each ot' these bars is attached to the beam, and the other end of each to the top of the post. The

5o bars have holes for the insertion of a loose pm, 2c.

A lever, K, is pivoted at L on top of the beam. A portion of the rear end occupies the space between the two uprightsegment-shaped bars, and said lever is then bent upward atl, V and then by an angular bend projects to the` rearward, as lat 2. This rear projecting part l2 constitutes a handle. The front end ot' the lever loosely grasps the bolt H between two collars, 3, rigidly fixed tothe bolt, whereby, while 6o the bolt may turn freely in the grasp ot' the lever, the said bolt or the end ot' the beam will be moved vertically up'or down, according as the lever is raised or depressed. lf the hau-` dle'2 atthe rear end of the lever be depressed, 65 the e'ect is to lower the front end. ot' the beam, and thereby tip the plow-pointand cutter down to enter the ground. It' the said handle be raised, the effect is to elevate'the front end of the beam and cause the weight to rest upon 7o the wheels, and thereby lift the plow entirely from the ground, in which position the plow may, by means ofthe three wheels, be moved over the road to any place.

Two horizontal arms, N are rigidly attached 7 5 to the post and project rearward. Each arm has a bearing, through which the tiller-post P ot' the steering-wheel turns. This Vtiller-p'ost cannot, however, move endwise through the bearings. The lower end ot' the tiller-post is So bifurcated, as at 4, to straddle the' steeringwheel, 'and a pin, 5, passes through the bifurcation on each side of the wheel and through the hub ofthe wheel.

A pivot-pulley, It, is' mounted on the upper 85 part of the tiller-post, and a chain, S, passes partly around this pulley, and one end ot' the chain is attached to one end ot' a horizontal guide-bar, T, on top of thev bolt H, and the other end of the chain is attached to the oppo- 9o siteV end of the said guide-bar. By this arrangement it will be seen that when the tillerpost and steering-wheel are partly turned, the front wheels and axle arelikewise turned,there l by changing the direction in which the plow is to move..

Two guide-levers,U,are attached to the tillerpost, and by these the latter may be turned, and they also serve for raising the plow. Y

A set-screw, V, is provided in one of the horizontal arms, and the end of this screw may' be made to press against the tiller-post and,

IOO

' 2 i acacia by holding the latter rigid, prevent lateral B, the front wheels and their axle, an upright motion of the steering-wheel when the plow is in operation.

It will be seen I dispense with the two plowhandles usually employed. Thus, when not lifting the plow, at least one and frequently both hands may be free. When my plow reaches the end of a furrow, an upward movement of the lever-handle raises the plow off the ground. The lever is kept up by placing the loose pin w through holes in the upper part of the segment-shaped bars under the lever. The plow may then be moved on lthree wheels to the point where the front end of the next furrow is to be made. Any direction can be given to the plow by the three wheels and steering device. The np-and-down movement ot' the lever regulates .the depth ot' the cut which the plow will make in the land. By my plow more work can be done in4 heavy soil with less manualattendance than any plow of which I have knowledge.

The shape of the cutter, mold board, and landside are immaterial so far as the working of my invention is concerned, for whatever may be the alleged advantages of plows of different makes, or plows having cutter and moldboard shaped differently from mine, this invention is applicable to all ot' them.

Having described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a plow, the combination of the beam bolt, H, attached to the axle passing loosely through the beam and having on top a horizontal guide-bar, T, a pivot-pulley, R, at the rear end of the plow, and a chain, S, passed around the pulley and havingits ends attached at opposite ends of the guide-bar, as set fo'rth.

2. In a plow, the combination ot' the front wheels, a bar, T, to guide the front wheels, a rear steering-wheel, E, having a tiller-post, a.l pivot-pulley on the tiller-post, and a chain passed around the pulley and having its ends attached at opposite ends ofthe guide-bar, as set forth.

3. In a plow, the combination, with the moldboard and landside, of a steering-wheel at the rear, a tiller-post directly connected to the steering-wheel, and guide-levers attached to the tiller-post, as set forth.

4. In a plow, the combination of the beam A, an upright post, I, secured to the rear end ot' the beam, horizontal arms N, rigidly attached to the upright post, a tiller-post having its bearings in the arms, and a steeringwheel adapted to be guided by the tiller-post, as set forth.

In testimony whereof I atlix m y signature in presence of two witnesses.

PEDRO A. FOMINAYA.
