THOMAS RICHMOND, OF SAN MARCOS, TEXAS.

PLOW.

SPECIFICATION forming part of Letters Patent No. 690,033, dated December 31, 1901.

Application filed April 30, 1901. Serial No. 58,196. (.ll'o model.)

To all whom zit may concern.-

Be it known that I, THOMAS Rronnonn, a citizen of the United States, residing at San Marcos, in the county of Hays and State of Texas, have invented a new and useful Plow, of which the following is a specification.

The invention relates to improvements in plows.

The object of the present invention is to improve the construction of plows and to provide a simple, inexpensive, and strong construction for adjustably supportinga rudder-blade adapted to be employed in connection with a middle-breaker moldboard.

The invention consists in the construction and novel combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a plow constructed in accordance with this invention. Fig. 2 is a horizontal sectional view on the line 2 2 of 1. Fig. 8 is a detail perspective view of the adjustable rudder-blade.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a plow-beam, preferably constructed of metal and having its rear end curved downward, and pivoted to the rear end of the plow-beam is a pair of standards 3, perforated between their ends for the reception of the pivot at and extending upward and downward from the rear end of the plowbeam. The standards are spaced apart at their lower ends by a block 5, and the lower arms or portions of the standards are adapted to receive a middlebreaker moldboard, (not shown,) and the upper portions or arms of the standards are arranged at opposite sides of the rear portion of the beam and are adapted to clamp the same, being held in engagement with the beam by means of a transverse bolt 6. The bolt 6, which is provided with a suitable nut, passes through perforations of the upper ends of the standards and is adapted to be readily loosened to permit the standards to be readily adjusted to arrange the moldboard in proper position.

The rear end of the plow-beam supports a pair of handles 7, which are provided at their lower ends with plates 8, secured to the inner faces of the plow-handles 7 and to the side faces of the plow-beam and interposed between the same and the standards. The plates of the plow-handles are secured to the plow-beam by the pivot L and by a transverse fastening device 9, located in rear of the pivot 4. The plow-handles are also braced by rods 10, extending forward from the upper portions of the handles and secured to the plow-beam in advance of the standards by a transverse fastening device 11. The rear ends of the bracing-rods 10 are bent inward at right angles and are secured to the plowhandles; but the bracing-rods may be attached to the latter in any other suitable manner.

The plow is guided by an adjustable rudder blade 12, pivoted at its front end between a pair of longitudinal supporting-bars 13 and connected with the plow-handles by a pair of braces 14.. The longitudinal bars 13 are pivoted at their front ends to the standards ata point below the rear end of the plow-beam by a transverse fastening device 15, and the pivot 16, which connects the front end of the blade 12 to the bars 13, is arranged at a point between the ends thereof and also passes through the lower ends of the upright braces 14. The rear ends of the longitudinal bars 13 are perforated for the reception of a bolt 17, which passes through an approximately vertical slot 18 in the rear portion of the blade 12 and which is adapted to be adjusted to clamp the blade in the adjusted position of the latter. The blade has a lower inclined front edge, and the upright braces 14:, which are provided at their upper portions with series of perforations 19, are secured to the plow-handles by bolts 20 or other suitable fastening devices, which permit the braces to be adjusted to swing the longitudinal bars 18 and the blade 12 upward and down ward. The blade is firmly clamped between the rear portions of the longitudinal bars and may be readily adjusted to arrange it to suit the plow.

It will be seen that the rudder-blade is capable of ready adjustment, both by the upright braces and by the means for connecting it to the longitudinal bars, that the latter are pivoted at their front ends in order to swing the blade bodily upward and downward, and

that the standards may be readily adjusted by loosening the fastening device at their upper ends when it is desired to adjust the plow.

What I claim is 1. The combination of a plow-beam,handles connected therewith, standards pivoted between their ends to the plow-beam and adjustably connected with the same, the longitudinal bars extending rearward from the standards and hinged at their front ends, a blade mounted between the longitudinal bars and braces connecting the blade with the handles, substantially as described.

2. The combination of a plow-beam,handles connected therewith, a longitudinal bar extending rearward beyond the plow-beam and located beneath the plow-handles and hinged at its front end adjacent to the lower ends of 4. The combination with a plow, of a pair of longitudinal bars hinged at their front ends to the plow, a blade arranged between the rear amass portions of the longitudinal bars and pivoted at its front end to the said bars, and provided with a slot, a fastening device arranged in the said slot and connecting the rear portions of the bars, and braces adj ustably connecting the bars with the plow-handles, substantially as described.

5. The combination of a plow-beam having a downwardly-curved rear portion, plow-handles extending upward and rearward from the back of the beam, longitudinal rods extending from the beam to the plow-handles, the standards pivoted between their ends to the rear end of the plow-beam, and arranged at opposite sides of the same and provided with a fastening device connecting their upper portions and holding the same in engagement with the beam, the longitudinal bars pivoted to and extending rearward from the standards, the blade arranged between the longitudinal bars and pivoted at its front end to the same, means for adjustably connecting-the blade to the said bars, and braces extending upward from the bars and adjustably secured to the plow-handle,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

THOMAS RICHMOND.
