UNITED sTATEs PATENT oEEioE.
THOMAS J. MAYALL, OF ROXBURYVMASSACHUSEITS."
STEEL.
Specification of Letters Patent No. 26,277, dated November29f1859. i
y To all whom t may concern:
Be it known that I, THOMAS J. MAYALL, of Roxbury, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Steels or Implements Used for Sharpening Table- Knives, &c., and that the following description, taken in connection with the accompanying drawings hereinafter referred to, forms a full and eXact specification of the same, wherein I have set forth the nature and principles of mv said improvements by which my invention may be distinguished from all others of a similar class, together with such parts as I claim and desire to have secured to me by Letters Patent. b
The figures of the accompanying plate of drawings represent my improvements.
Figure l is a plan or top view of my improved steel Fig. 2 is a central, longitudinal vertical section of the same. Figs.
3 and 4: are sectional views showing the molds.
The object of my invention is to form a steel for sharpening table knives, &c.,
which shall be cheaper and more durable than those heretofore manufactured. I ac-` complish these results by making the steel of india rubber or gutta-percha, combined with emery. sand or other gritty materials and sulfur compounded in any desired proportions. I make a composition of about the following proportions, viz: l5 lbs. of emery, sand or other gritty materials, l lb. of rubber or gutta-percha and 5 oz. of sulfur. These ingredients are perfectly combined and mixed together and the composition thus formed is then placed in metallic molds a a-ZJ b, subjected to pressure and heated from fifteen minutes to four hours at a `temperature of from 260O to 300 Fahrenheit, much less time being required when a high pressure is used than when a low pressure only is obtained.'` This compositionthus lne-3` "ii 1 be formed in the molds, `of hard-gum:com@` l pound, at the same time with the alcove` named composition, or of wood, metal, or` y other suitable material and lboth the `inner u i 15.01 other substances than the composition `above i named, the sharpening composition being .y
comes hard and durable.v The handle ccan body and handle Aof the f steel may :be `of formed in suiicient thickness upon the said inner body in the molds.
The composition above stated and the de-` gree of heat to beemployed. y
In order to `give suiicient strength to the steel, I use apiece of lnetal in theform of a tapering rod or otherwise, for the cen ter.
is heated. I have foundit best in practice to cover this metallic center with a thin coat of liquid rubber cementwhich causes the i emery coating to adherefmoreperfectly to Wood or other stiff substances f 17.0. 1
the metal. can be used in place ofthe metal, butthey are not desirable substitutes.
Having thus described my "improvements `I shall state my claimfas follows. y
That I claim as my invention and desire .3 As a new article ofmanufacture,a steell y y or implement for sharpening` Stable knives` &c. formed of india-rubber or gutta-perchazi l to have secured to me by Letters Patent, is-f 551 grecs of heat to be employed admit of many l; variations an-d therefore do not limit my` 1 self to the proportions named or to the de- The emery composition isI placed upon` the outside of `this metallic center before it l` with which emery, sand,`or other suitable gritty substances are incorporated, substan- VVitnesses: y y
