THOMAS G. KING, OF ATLANTA, GEORGIA.

To all whom it may concern:

Be it known that I, THOMAS G. KING, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Plows, of which the following is a specification.

The present invention relates to improvements in plows, and is designed particularly to provide a new form of plow beam.

The principal object of the invention is to overcome certain dil'liculties and objec tions in plow beams made of single pieces.

As new constructed most plow beams require heavy material in order to provide a strong metallic beam, and the present invention is designed to substitute for the sin gle heavy beam, a beam made up of separated pieces which are secured together to form a light but strong metallic unit.

With these objects in View the invention consists in a two-piece metallic or steel beam constructed and arranged in the novel mannor as will be hereinafter set forth.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of the invention.

Figure 1 is a side elevation of a plow constructed accordingto the principles of the invention, a portion of the handles being broken away. Fig. 2 is a plan view of Fig. 1. Fig. 3 is a transverse vertical section of Fig. 2 on line 33.

In the preferred embodiment of my in-- vention I employ a beam made up as to its main portion, of the side arms 1 and 2 which are connected at their front ends by the clevis 3 and bolt 4. As seen in Fig. 2, the frame bars which are of flat metal, preferably steel, are spread apart and held in this spread position by means of lugs 5, three being shown. These lugs extend across the space between the frame bars, and are provided with shoulders 6-0 which overhang or extend over the tops of the bars and provide secure braces to prevent movement of the frame bars 1 and 2. A plurality of bolts 7, 8 and 9 are employed to secure these lugs to the frame bars 1 and 2, and the bolts are passed through perforations in the lugs and in the frame bars, provided for the purpose. The rear ends of the main portion of the beam are Specification of Letters Patent.

brought together and bolted at the sides of a brace plate 10 which is perforated for the passage of the bolt 11 which holds the frame bars 1 and 2 together at this point, and upon which the handles and plate 10 may swing as a pivot.

A second piece of the plow beam is fastened with the two side plates 12 and [3. These side plates are located on the outside of the frame bars 1 and 2, and at their forward ends are secured on the bolt 8, and the intermediate bolt 9 is also passed through these side plates to fasten the plates 1 and 2, 12 and 13 rigidly together. At the rear these side plates 12 and 13 are brought together and curved downwardly to provide a shank 14; upon which the plow point 15 is attached as usual, and the shank may be adjusted on the pivot bolt 9 relative to the main portionof the beam.

The handles 16-1G are secured by bolts 17-17 to the coupling or brace 10, and the pair of side braces 18-18 extend from the bolt 8 to the rear and are secured by the bolt 17 to the handles 16.

The handles may be adjusted with relation to the shank by first removing bolt 17 and swinging the handles on bolt 11 as a center to desired angle, and the bolt 17' may then be fixed in position to hold the braces 18 in position. The plow and shank may also be adjusted with relation to the beam by first removing bolt 8 and turning the shank on bolt 9 as a center and then the parts are clamped by replacing the bolt 8 in proper holes in the beam and ends of shank. I

From this description it will be observed that a rigid compact and light brace twopiece beam is provided which is strong, and comparatively light in weight, and overcomes many objections and difficulties encountered in the one-piece beams for plows.

While I have illustrated the side arms and plates of the two framepieces of flat metal it will be understood that I may use other forms of metal beams such as channel beams, and in this case it will be understood that the spacing lugs or blocks also may be changed to suit circumstances.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. The combination of a plow beam comprising spaced separate side arms and blocks having lugs engaging the edges of said arms,

av elevis joining the forward ends of said arms, handles, a handle brace plate pivoted to the rear ends of said arms, braces connecting the beam and handles, and an adjustable plow shank pivoted to said arms.

2. The combination of a plow beam com-- prising separate side arms, a clevis joining the front ends of said arms, handles, a handle brace plate pivoted to the rear ends of said arms, adjustable braces connecting the 10 beam and handles, and an adjustable plow shank pivoted to said arms.

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