s. TEFFT.
Plow. I No. 2,762. l Patented 'Aug. 25, 1842.
UNITED STATES PATENT Orrrcnt JAIRUS S. TEFFT, OF AMHERST, EEVVYORK.
IMPROVEMENT IN THE CONSTRUCTION OF PLOWS.
Specification forming part of Letters Patent No. 2,762, dated August 25, 1842.
To all whom'tt may concern:
' Be it known that I, JAIRUS SFTEFFT of the having a recess at its forward end to receive a share, 0, which is fitted thereto, its front edge extending up and forming the cutter, and forward, so as to form the poiutof the plow below.
'This form of mold-board and share are similar.
to many now in use and well known, except in the following particular: theyincline from the bottom of the plow upward over toward the land at the cutting-edge, the landside B also incliningunder, so as to .leanover onto the land. This form of the landside will cause the plow to cut afurrow-slice'the cross-section of which forms a rhomboid, and is much easier turned over than one out by a plow whose landside is vertical or inclines" the other way. If a cutter is used before the cutting-edge of the share it is attached to the side of the.plow-beam, and
has the same inclination asthe landside. mold-board is also formed flat on the under side, so as to receive another share on the under side when it is desirable to change from a cast to a wrought iron share. This share E is .formed of a flat triangular plate of iron, the
cutting'edge of which is slightly convex and sharpened. It is fastened in its place on the underside of the mold-board by a bolt passing through them both. When this share is substituted for that marked 0 a false share, F, is affixed, which fills the recess in the mold-board, it being of the same shape-as the upper part of the share (3, the lower or cutting edge being formed by the share E. By this arrangement either a cast or wrought iron share can be used, as the nature of the soil requires.
What I claim as my invention, and desire to secure by Letters Patent, is
1. Constructing the mold-board-and shares (land E F of a plow so thata share can be applied to either the upper or under side of the mold-board, in the manner and for the purpose herein set forth. 2. The inclination of the cutter and landside so as to cute rhon'iboidal furrow-slice, as above described- J AIRUS S. TEFFT. Witnesses:
