PLOW.

Specification of Letters Patent.

Patented Nov. 21, 1911.

Application filed March 13, 1911. Serial No. 614,049.

To all whom it may concern:

Be it known that I, GEORGE PUI-IA, a subject of the King of Hungary, residing at Buifalo, in the county of Erie and State of New York have invented new and useful,

Improvements in Plows, of which the following is a specification.

This invention relates more particularly to wheel plows of the kind in which the plow is pivoted to the beam and provided with means for raising and swinging it clear of the ground in moving the implement from place to place.

One of the objects of my invention is to improve the implement with a View of simplifying the construction of the plow-raising mechanism and rendering it convenient in operation.

Another object is to provide simple and reliable connecting means between the plow and the oolter, whereby the oolter is caused "to follow the movements of the plow.

In the accompanying drawings consisting of 2 sheets: Figure 1 is a sectional elevation of the improved plow. Fig. 2 is a top plan view thereof. 'Fig. 3 is a transverse section on line 33, Fig. 1, on an enlarged scale. Fig. 4 is a longitudinal section on line 4 1, Fig. 3. Figs. 5 and 6 are transverse sections on the correspondingly numbered lines in Fig. l.

Similar letters of reference indicate corresponding parts throughout the several views.-

The front portion of the plow beam preferably consists of a single bar A, while its rear portion comprises a pair of spaced parallel bars A riveted or otherwise secured to the front bar or section, as shown at a. The front portion of this beam is supported upon a suitable truck comprising an axle B and wheels B B C indicates the plow-bodyhaving an upward extension or front standard 0 pivoted near its upper end to the rear portion of the plow-beam by a transverse pin 0 to permit the body to swing lengthwise of the beam. At its lower rear end the plow body carries a roller or caster D upon which it is supported when its front portion is raised clear of the ground in transporting the implement. This roller is swiveled in a bracket D secured at one side to the adjacent heel of the plow and at its opposite side to a brace d fastened at its front end to the back of the plow-share.

Extending upwardly from the rear portion of the plow-body is a rigid rear standard or rack-bar E the toothed portion of which is 0111" ed concentrically with the pivot c and is engaged by a gear-segment f mounted on a longitudinally-swinging hand lever F pivoted at f between the rear sections A of the plow-beam. The rear supporting wheel D rests normally upon the ground, and upon pulling the hand lever F backwardly, the rear portion of the plowbeam is caused to rise on the rack bar E and at the same time the front portion of the plow swings upwardly to the position shown by dotted lines in Fig. l, thus raising the plow-body clear of the ground and permitting its easy transportation from place to place. Upon swinging the hand lever forwardly, the plow is lowered to the position shown by full lines in Fig. 1. This lever may be locked in position by any suitable means, the preferred devices shown in the drawings consisting of a notched segment 9 secured. to the plow-beam and a cooperating locking pawl 9 carried by the lever.

At its rear end the plow-beam may carry the usual handles H for controlling the implement when used as a hand-plow. It is also preferably provided with a removable drivers seat I, so that the implement may be used as a riding plow. In the construction shown in the drawings, the arm or shank 2' of the seat is provided at its lower end with hooks or lugs 2' which embra re a stem 2' extending upwardly from the bracket D This construction permits the seat-arm to be applied to said stem by simply slipping its hooked portion over the same, and to be as readily detached therefrom when the seat is not desired.

J indicates the oolter arranged above the plow-point in the customary manner. It is.

carried by a bracket or holder J preferably pivoted to the plow-beam by a transverse pin j, thus permitting the colter to swing lengthwise of the beam. A link 70 connects the upper end of the oolter with the upper end of the front plow-standard c, the latter and the colter shank extending above their pivots 0 and j, as shown. By this connection, when the plow-body is raised clear of I the ground, the upper end of the standard 0 is swung rearwardly, swinging the upper portion of the oolter in the same direction and its lower portion in a forward direction to the position shown by dotted lines in Fig. 1. The colter while occupying the desired position relative to the plow-point in the normal operation of the implement, is by this construction caused to swing forwardly and upwardly with the plow-point when the plow is raised, keeping the colter out of contact with the plow-point at all times and preventing injury to the latter and the colter.

The colter is preferably capable of angular adjustment laterally or crosswise of the plow to suit different conditions or kinds of soil. When the ground is comparatively soft, it is desirable to set the lower end of the colter so as to incline toward the mold board of the plow, while when the soil is hard or contains stones it is desirable to set the colter to incline in the opposite direction. In the construction shown in the drawings, the shank of the colter is arranged in upper and lower loops f 7' of the holder J and fitted therein in such manner that it is capable of rocking or inclining laterally, as indicated by dotted lines in Fig. 5. As shown in the last-named figure, the colter-shank is fitted somewhat loosely in the lower loop y' while the sidebars of the upper loop are spaced a considerable distance apart and carry transverse adjusting screws j which bear against opposite sides of the colter shank. It is obvious that the angle of the colter can be readily adjusted as desired by turning one of these thumb screws forward and the other backward. The truck wheel B located on the mold-board side of the plow is preferably of greater diameter than the other wheel B and adapted to run in the furrows to serve as a gage wheel toward and from which the front portion of the plow-beam is adjustable for regulating the space between the furrows.

L indicates an arch secured to the axle B and adjustably supporting the front portion of the beam A; g the draft pole attached to the axle, and R forwardly converging draft-chains connecting the rear end of the pole with the outer end of a cross head S secured to the central portion of the plow-beam.

I claim as my invention:

1. The combination of a plow-beam, a plow-body having front and rear standards, said front standard being pivoted to the beam to swing longitudinally thereof, a supporting roller carried by the lower rear portion of the plow-body, and raising and lowering means engaging said rear standard.

2. The combination of a plow-beam, a plow-body having a standard pivoted to the beam to swing lengthwise thereof, a colter having a shank also pivoted to the plowbeam to swing lengthwise thereof, the coltershank and said plow-standard extending above their pivots, a link connecting the upper ends of said standard and shank, and means under the control of the operator for swinging the plow-body into and out of 0perative position.

Witness my hand this 8th day of March, 1911.

GEORGE PUHA.
