JAMES JOHNSON, OF WOOSTER, OHIO.
IM PROVEMENT IN PLOWS.
Specification forming part of Letters Patent No. 4.552, dated May 30, 1846.
To all whom it may concern:
Be it known that I, JAMES JOHNSON, of Wooster, in the eountyof Wayne and State of Ohio, have invented a new and useful Improvement in Flows; and I do hereby declare that the following is a full, clear, and exact description of the principle or character which distinguishes my invention from all other things v of the underside of the plow; Fig.3, the inside of the mold-board; Fig. 4, part of the inside of the landside.
The same lettersindioatelike parts in all the figures.
My invention consists in the mannerof combining the mold-board and landside oftheplow and bracing them and connecting them togcther.
The mold-board and landside are in their outer form similar to those now in common use of the most approved shape. On the inside of the mold-board atabouthalt' its height, near the front edge, there is an inward projection, a. (This is shown in Fig.2 and by dotted lines in Fig.1.) Just belowit is a projection, b, from the Iaudside that overlaps it. Through both a bolt passes which extends up in a line curved forward through the mold-board, which projects in front of the standard above the cutter of the share, and in aline therewith at the point if, so as to prevent the dirt from lodging between them, and thence through the beam forming the brace c. On the inside of the lower front corner of the mold-board there is a projection, d, which extends back on a line with the insideot' the landside. On the face of this projection d, next the landside, there is a groove, as shown in Fig. 3, into which a projection, c, Fig. 4, fits, by which both parts are held steady, fastened by a bolt passing through both. The other parts of the plow are made ing them by means of the projections a and b,
the bracing-rod c, and the connections 11 and e below, in the manner and for the purpose specified.
JAMES JOHNSON.
