PLOW-COLTER FASTENING.

SPECIFICATION forming part of Letters Patent No. 464,525, dated December 8, 1891.

Application filed April 30, 1891. Serial No. 391,134. (No model.)

To all whom it may concern:

Be it known that I, RUFUS MCOULLOUGH SHERROD, a citizen of the United States, re-

"siding at Bells Depot, in the county of Crockett and State of Tennessee, have invented certain new and useful Improvements in Plow- Oolter Fastenings; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it. appertains to make and use the same.

The invention relates to the colters or knives which are arranged in front of plows to cut sods, roots, and other vegetable obstructions on or in the ground; and it consists in the particular means which I employ to secure them adjustably in position on the plow-beam.

Figure 1 of thedrawings isa perspective view of a plow with a colter secured to the'plowbeam by the combination of instrum entalities which constitute my invention; Fig. 2, a detail perspective view of the plate whichIscrew or bolt to the under side of the plow-beam, and Fig. 3 a plan view of the plate which is bolted to the upper side of the plow-beam.

In the drawings, A represents the under plate, which has on one side of its bottom an integral nut a, in which works the screw against the shank of a colter O, that passes up through a mortise d in the plow-beam D, as well as through the slot a of the under plate, the latter being also provided with boltholes a a E is the top plate, having the three slots e 6' e through the first and last of which pass 3 5 the screws ff while through the middle one 6 passes the colter-shank o. By loosening the screws B f f the plate E may be moved back or forward and allow any desired pitch to be given to the colter and there held by 0 tightening said screws, the lower side screw B effectually preventing any lateral play to the colter.

I may make serrations across the slots 6 6 as shown about the slot e so that thehead of 5 screw may take a better hold on the plate on the plate E; but it is not probably necessary. One of the screws a a which hold the plate A, is utilized to hold one end of the brace II,

Whose other end is made fast to the plow- 50 his SHERROD.
