Description
NITED STATES PATENT OEEICE.
EDWIN EEMENT, 0E Eos'roEIA, O'Hro.
||v| PRovEM ENT .IN PLOW-POINTS.-
Specitication forming part of Letters Patent No. 36,4147, dated September 16, 1862.
To all whom it may concern.-
Be it known that I, EDWIN BEMENT, of Fostoria, In the county of Seneca and State ot Ohio, have invented new and useful Improvements in Flows; and I do hereby declare that the following is a full and complete description of the construction and operation ot' the same, reference beinghad to theaccompanyingdrawings, making part ot' this specification, in whichl Figure l is a perspective view. Fig. 2 is an inverted View. Fig. 3 is a section in the direction of the line a a, and Fig. 4 is a section in the direction of the line b b.
Like letters refer to like parts.
The nature ot' my invention is explained by the following statcvnent: It is well known to all who have been concerned in the Inanufac.
turc or use of cast-iron plows that the points, it' chilled sufficiently to stand any considerable wear, are liable to break unless they are made very thick, and then the points wear rounding and soon become unserviceable. By my iluprovement, hereinafter described, this difficulty is obviated. The ribs on each side of the point not only strengthen the point and protect it from breaking by vertical strain, but enable me to make the point longer and thinner, and protect the corners from wearing oi rounding, or becoming beveled upon the under side. `The ribs on the wing also strengthen the part, and serve to keep the plow steady in breaking up swat-d. 3 y
` yA in Figs. 1 and 2 represents the plow-point.
This is made larger and thinner than usual, as is indicated by the dotted lines in Figs. l and 2. Both upon the upper and under surfaces of the point are cast the ribs B B and C C. These as well as the point are made thin, and extend both above and below the point proper about half an inch, as shown in the cross-section, Fig. 4. The space between thel ribs may therefore be made quite thin and still possess the requisite strength to withstand both the lateral and vertical pressure, while the ribs B C, in addition, protect the corners of the point from wearing on. Those on the lower side may be smaller than those above,or wholly omitted.
DD represent ribs cast upon the win g, which may, in consequence, be-made thinner and still possess the requisite strength. These ribs serve also to keep the plow steady. In turning sward-gronnd one or more may be used. Their E DWIN BEMENT.
