To all whom 'it may concern.'

Be it known that I, JACOB SRAMEK, citizen of the United States, residing at Bryan, in the county of Brazos and State ofTexas, have invented certain new and useful Improvements in Plows, of which the following is a specification.

This invention has relation to plows and more particularly to reversible plows.

The object of the invention is to provide a plow having a pivoted standard and a moldboard and point mounted on each end of the standard and either adapted to be swung into position in front of a fixed landside whereby the dirt may be thrown either to the right or the l-eft as desired.

Another object resides in a fastening means comprising a single lever and whereby one of the, points may be locked in fixed relation to the landside and the standard also prevented from swinging.

Finally the object of the invention is to provide means of the character described that will be strong, durable, efficient, and easy of operation, simple and comparatively inexpensive to construct, and also in which the several parts will not be likely to 'get out of working order.

With the above and other objects in view, the invention has relation to certain novel features of construction and operation, an example of which is described in this specication and illustrated in the accompanying drawings, wherein:

Figure 1. is a side elevation of the improved plow, Fig. 2. is a detail ofthe standard hanger and adjacent parts, Fig. 8. is a detail in section taken on the line w-w of Fig. 1, Fig. 4. is a longitudinal section through the landside and adjacent moldboard and point, and Fig. 5.' is a detail in section taken on the line S-D of Fig. 1.

In the drawings, the numeral 1 designates a plow beam terminating at its rear end in a stock 2 which is split and spread apart at its lower end to form a bifurcated foot as indicated at 3. The split portion 3 enters and is secured in a rectangular landside 4 beveled at its forward end as indicated at 5. Suitable handles 6 are secured at their lower ends to the stock 2 just above the landside. At the upper end of the stock 2 a hanger yoke or bracket embraces the plowbeam. This hanger is held in place by a shouldered bolt' 8 passed through the plow beam and the extremities of the yoke and also by a plate 9 lengaging threaded studs 10 extending from the yoke and fastened in place by nuts 11 as shown in Figs. 1 and 2. The hanger is bent at an angle and provided with a rounded shank 12 inclining slightly upward and extending forward under the plow beam. A standard 14 is provided at its central portion with a suitable bearing 13 which extends from one side thereof and Yreceives the shank 12. This bearing is confined on the shank by a nut 15, the outer end of the shank being screw threaded to receive the nut. At each end the standard has a forwardly curved portion 16v and the stand-ard is bent so as to cause the curved portions to extend over and under the beam 1. This is necessaryv as it is obvious that the bearing 13 will cause the central portion of the standard to stand at one side of the plow beam. Each portion 16 is cut out at 17 so as to swing over and in close proximity to the beveled portion 5 of the landside. The extreme end of each portion 16 enters and is secured to a suitable share or point 18 and above this point a suitable moldboard 19 is also secured to each curved portion 16. The lower share 18 has its landside 20 terminating adjacent the forward end of the landside 4 and in alinement therewith.

With the parts adjusted as shown in Fig. 1 it is apparent that in plowing the soil would be thrown to the left, but should the standard 14 be revolved upon the shank 12 to bring the upper moldboard and share down into relative position with the landside 4, the soill would then be thrown to the right. l

It is obvious that some means must be provided for locking the standard against revolution and holding the share and moldboard in fixed relation to the landside 4. For accomplishing this a bent lever 21 is pivoted between the handles 6 `on a transverse bolt 22. The lever is of the bell-crank leg a short distance below the point of intersection of the leg. The upper leg of the lever extends rearwardly between the plow handle so as to be within easy reach of the plowman. At the intersection of the legs of the lever 21, a bail 23 is loosely mounted. This bail extends forward and has its free ends turned outward, and each engaging in the lower end of a latch arm 24. The bolt 8 has reduced portions 25 extending from its shouldered portions on each side.v As shown in Fig. 5 the latch arms are pivoted near their central portions on the reduced pori' tions 25 of the bolt. Washers 26 are placed againstV the outer sides of the arms and the eyes of brace links 27 are engaged over the portions 25 and bear against the washers, the rear ends of the brace links being attached to the handles 6 as is shown in Fig. 1. The brace links are held on the portions 25 by nuts 28.

When the lever 2l is swung rearward as shown in Fig. 1 the upper ends of the arms 24 will be swung forward and one of them against the side of the standard 14, depending on which side of the beam the standard is swung. By swinging the lever 21 forward theupper ends of the arms 24 are swung rearward out of the path of the standard which is then free to revolve. end of the lever 21 has pivotal connection with the rear end of a plunger latch bar 29.

' This plunger is mounted to slide longitudinally in the landside 4 between the portions 3. When the lever 21 is in the position shown in Fig. 1 the forward end of the plunger extends beyond the landside and lies against the inner side of the curved portion 16 of the standard and when the lever is moved forward the plunger is withdrawn into the landside and out of the path of the said portion 16. v

When the plunger is extended it will hold the standard against revolution in one direction and in order to prevent movement in the opposite direction a stop lug 30 is turned down from each frog 3l so as to engage the side of the landside 4 as is best shown in Fig. 3. It is obvious that the plunger 29 projects between the lug and the standard. It is also apparent that by simply swinging the lever 21 forward the plunger is withdrawn and the latch arms swung out of the path of the standard thereby permitting the latter to be freely revolved.

A plow constructed in accordance with this invention will plow the land smooth to one side without leaving a trench in the soil. In plowing soil that has been ridged in rows the year before, when plowing across the row the soil will be level substantially the same as would be done with a harrow. When listing the soil the v middle can be thrown at one furrow to each row vbination, a plow beam having a bifurcated The lower without the use of middlebuster. Vhen plowing hill or sloping land, the land can be plowed up hill or the levee` thrown on the hill side to prevent washing of the soil.v To accomplish these results it is merely necessary to swing the lever 21 forward and turn the standard yto bring the desired moldboard and share into position. v
