Specification of'Letters Patent.

Application filed April 8, 1914. Serial No. 830,444. I

I To all whom it may concern Be it known that I, HENRY KNIGHT, citizen of the United States, residlng at Collins, in the county of Covington and State of Mississippi, have invented certain new and useful Improvements in Plow Attach ments, of which the following is a spec fication. I v v I This invention relates to attachments to plows, and has for one of its objects to provide a simply constructed device whereby the plow is guided or steered in its movement through the ground.

Another object of the invention is to provide a. device which may be adapted without material structural change to plows of various forms and sizes.

Another object of the invention is to provide a device of this character which may be adjusted to operate at any required depth and to adjust the inclination of the moldboard relative to the shoe or landsideg \Vith these and other objectsin view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims.

The improved device may be applied without material structural change to plows of various forms and sizes, and it is not designed therefore to limit the invention in this respect, but for the purpose of illustration the improved device is shown applied to a conventional plow, and in the drawings illustrative of the preferred embodiment of the inventionFigure 1 is a side elevation of a portion of a plow with the improvement applied. Fig. 2 is a rear elevation with the beam of the plow in section on the line 22 of Fig. 1. Fig. 3 represents the parts of-the.improved device separated and in perspective.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters. p

The beam of the plow is represented conventionally at 10, the standard at 11, and the hoeqor moldboard at 12. The handles arerepresented at 13 and the standard brace at 16, these parts being'of the usual construction. p, v

A shoe, represented conventionally at 17, is united preferably by a pivot 18, to'the lower end of the standard Ilfiand extends rearw'ardly thereof as shown. The stand-.

aid of plows of this character is generally constructed in two parts and clamped to Patented Nov. 10, 1914..

the opposite sides of the beam 10 by transverse bolts 19 and with a spacing block indicated at'-20 between the lower ends of the, beam members.

The improved device comprises coacting bars 2122 bearing upon opposite sides of the standard members 11 and likewise upon opposite sides of the shoe 17. The

=members' 2l22 are provided with" means whereby they are adjustably coupled to the standard, and for the purpose of illustration an improved means for such adjustment shown consisting in forming a plurality of apertures through the members 2122 as represented at 28, and through which one of the clamp bolts 19 is pivoted. By this t I means the bolt performs the two fold func-' tion of a means for clamping the standard members to the beam and likewise as a means for securing the members 2122 in position at their upper ends. ing a plurality of the apertures 23the members 2l22 maybe adjusted relativeto the beam members within therange of the ap ertures.

By provid- Bearing upon the outer face of the mem ber 21 is a plate 24, preferably formed with a cutting edge at its lower terminal and likewise provided with a plurality of ion-'- gitudinal apertures 25. The pivotbolt 26 by which the members 2122 are coupled to the shoe 17 is likewise utilized to pass through one of the apertures 25 and thus support the member 24 in position. An additional clamp bolt 27 mayalso. be employed through the apertures 25 and'likewise through the members 21-22 to more securely support the member 24 in position. By this simple means the member 17 is supported adjustably in position, while the member 24 is likewise supported adjustably in position so that the depth to which it operates below the lower line of the shoe may be controlled.

With a device thus constructed, it will be obvious that as the plow is drawn through the ground the member 17 cuts into the soil below the line of the shoe and serves as a guard or steering member to control the,

movement of the displacement.

. Having thus described the inventiomwhat is claimed as new is: Y 1. In a plow including a beam and standplow and prevent lateral ard, a shoe member connected to the standard and extending rearwardly thereof, a brace member adjustably connected at one end to the standard and pivoted at the other end to the shoe, a steering member having a cutting terminal, and means for adjustably clamping said steering member to the brace and maintaining the steering member in constant longitudinal alinement with the brace.

2. In a plow including a beam and standard, a shoe member connected to the stand ard and extending rearwardly thereof, coacting bracemembers bearing atv opposite sides of the standard and of the shoe, means HENRY WV. KNIGHT.
