PLOW- ADJUSTING MECHANISM- sPEoIFIoATIo v forming part or Letters Patent No. 761,883, datedJune '2, 1904.

Application filed DecemberZl, 1903. Serial No. 186,009. (No model.)

To all whom, it may concern.-

Be it known that I, WVILLIAM F. Gunner, a

citizen of the United States, residing at Leopold, in the county of Perry and State of Indiana, have invented certain new and useful Improvements in Plow-Adjusting Devices, of which the following is a specification.

This invention relates to mechanism for adjusting plows, and especially sulky-plows, to conditions and inequalities in the land.

The object of the invention is to place it within the power of the plowman to readily shift his plow both as to depth and side draft without dismounting or detaching his team; and the invention consists in certain combina- "tions and mechanisms, substantially as hereinafter described.

Figure 1 is a side elevation of a sulky-plow,

showing the essential features of my inven tion. Fig. 2 is a broken side elevation, partly in section, of plow-beam and traction and shifting-bar, partly broken away. Fig. 3 is a cross-section of plow-beam and elevation of clamping-plate on line 3 3, Fig. 2. Fig. 4 is a plan of the swivel-socket attached to plowbeam. Fig.' 5 is an elevation of swivel and adjusting-bar support;

The plow A may be of any usual construction. To the front of plow-beam B, I attach a socket G, which socket is firmly secured by bolts or in any other convenient manner. The socket may have straps C embracing the sides of the plow-beam. In the socket C a pintle D is secured, so as to be free to turn. A plate D and nut D engaging a threaded projection of the pintle, forms a convenient means of securing the pintle, while permitting it to swivel in the socket. The pintle D is rigid with a piece E, which has standards E projecting upward. Draft-bar F is pivoted between these standards on a strong pin G. vThe draft-bar F may be reinforced by side plates F, which pass outside the standards E, while the bar proper passes between them. The purpose of the construction is to have a strong connection between the draft -bar, swivel-piece, and plow-beam, but permitting the draft-bar to swing vertically and the plowbeam to swing horizontally on their respective pintles or pivots with relation to the swivel-piece. The draft-bar F extends forward of the plow beam and has the doubletree or other means of traction attached at its front end. The draft-bar Fhasan arch or gooseneck F which arches over the adjusting-plate H, which plate is attached to the plow-beam in rear of the swivel and point connections between the plow-beam and draftbar hereinbefore described. The plate H is firmly attached to the plow-beam by a loop H, which surrounds the plow-beam, or by other suitable rigid connections. Plate H c'ontains anumber of holes This plate may be a casting or otherwise. It preferably curves upward in an arc struck from the pivot G and also horizontally in an arc struck from pintle D and has holes H in vertical and in horizontal series.

The bar F has a spring-pressed bolt I extending forward from the rear curve of the arch or gooseneck into one of the holes H of the plate H. This bolt can be drawn back by a draw-rod K, extending along the draft-bar to handle L;

The rear end of the draft-bar F terminates near the seat of the sulky, and handle L can be manipulated by the rider on said seat to withdraw the bolt I from any hole H The draft-bar can then be raised or lowered or swung to either side and bolt I engaged with another hole in plate H. As the traction of the team is entirely on draft-bar F, this adjustment .of the draft-bar relatively to the plow-beam compels the plow to assume the newly-adjusted position as soon as the handle of the draft-bar is brought to its normal position near the seat of the rider. The rider or operator thus has it in his power to adjust his plow to out a deep or a shallow furrow or to turn more or less land without leaving his seat and generally without stopping his team. The grasp of the handle F* on the draft-bar may be relied on to control the plow, or a suitable bearing may be supplied on or near the seat to rclievethe strain of holding the draftbar.

From the above description it should be understood that my improvement gives the operator an almost instantaneous means for adjusting the plow to its work while passing over land of different character. It also enables the operator to quickly shift his plow to avoid a stone or stump or other obstruction.

I am aware that plows have been connected to the draft-clevis in various ways so as to permit a vertical ad uStment; but I am not aware of any construction whereby the operator has so full and complete control of the plow without changing the traction-point as in my device.

What I claim is 1. The combination with a plow-beam, of a pintle swiveled thereto, a draft-bar pivoted to said pintle, and means connected to the plowbeam and draft-bar whereby the beam may be adjusted both vertically and horizontally relatively to said bar.

2. The combination with a plow-beam of a draft -bar connected thereto by pivot and swivel connection, aspring-pressed bolt on the draft-bar, and a plate on the plow-beam provided with a plurality of openings with which said bolt may engage.

3. The combination with a plow-beam, of a horizontally-curved plate connected thereto, said plate having a plurality of holes arranged in horizontal series therein, a draft-bar connected by a swivel to said plow-beam, and a spring-pressed bolt on the draft-baa in position to engage either hole in said plate.

4:. The combination with a plow-beam of a plate rigidly connected to its upper face and having a series of perforations therein, a d raftbar connected to the front of the plow-bean'l by swivel and pivot connection, said dral'trear of said pivot, and means for adjusting the rear end of said draft-bar both vertically and laterally with reference to the plow-beam.

In testimony whereof I aiiix my signature in presence of two witnesses.
