METHOD 01E RECONDI'IIONING STEELE.
Application filed January 15, 1921. Serial No. 437,564.
To aZZ whom it may concern: I
Be it known that I, RICHARD S. HANNA- FORD, a citizen of the United States of America, and resident of Brownville, in the county of Neinaha and State of Nebraska, have invented certain new and useful Improvements in Methods of Reconditioning Steels, of which the following is a specification.
This invention relates to knife sharpening devices and particularly to means for maintaining the said knife sharpeners in effective condition; the said invention relating more particularly to the treatment of steels used by butchers and in households, which steels usually have a roughened surface to be applied to the knives for the purpose of sharpening the same.
It is an object of this invention to produce a steel having a plurality of grooves and in which the external surface of the steel is smooth except for the groves, thus to a great extent depending upon the edges of the surface of the steel formed by the grooves for the abrading or sharpening action on the knife.
t is a further object of this invention to proviee novel means for renewing steels which have become impaired or worn to an extent that they are ineifective and to that end, I provide novel means which when applied to the steel and when relative movement is imparted to the element and the steel, will form grooves of the character heretofore described, leaving the external surface of the steel substantially smooth.
With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.
In describing the invention in detail, reference will be had to the accompanying drawings forming partof this application wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a view in perspective of a steel having grooves;
Figure 2 illustrates a sectional view on an enlarged scale;
.Figure 3 illustrates a side elevation of a fragment of the steel on an enlarged scale; and
Figure 4 illustrates a detailed view of the material used for treating the steel.
In these drawings 5 denotes the handle of the steel and 6 the abrading portion thereof having grooves 7.
The sharpening element comprises a bind ing material to form a body 8 which will harden, such as cement and sand, having such strength as to withstand the strain incident to its use. The plastic material when in a plastic state is supplied with a steel cutting or abrading material 9 such as carborundum in a granular state and of such size as to prove effective in cutting grooves in the steel when there is relative movement of the steel and the element longitudinally of the axis of the steel, and while I have mentioned carhorundum as an ingredient which would prove effective in treating the steel, I wish it to be understood that other granular ingredients may be employed having the characteristics of carborundum in its ability to cut the steel to form grooves.
I claim:
The herein described method of reconditioning steels in a cold state consisting in applying a body carrying steel cutting granular material to the steel and effecting rela tive movement of the steel and the said element longitudinally of the axis of the steel thereby cuttinggrooves in the steel.
RICHARD S. HANNAFORD.
