Application med April s, 191e. serial No. 90,010.
il; ad 'whom z't may concern Be it known that I. WILLIAM THOMAS MILLER, a citizen of the United States, residing at Fresno,inxthe county of Fresno and State of California, have invented certain new Improvements in Safety-Razor- Blade Sharpeners, of which the following is a specification.
This invention relates to a simple and efiicient apparatus for sharpening safety razor blades and has for its object to provide in such a machine an article 'of few parts readily portable and of an economical constructlon and novel design by means of which safety razor blades may be quickly and eas'ly sharpened to a desired keenness for sh ving. l
With this end in View the apparatus consists of the novel combination and arrangement of arts hereinafter described and pointed out in the appended claims, reference being had to the accompanying draw,
ings, in which: A
Figure l is a front elevation of the apparatus mounted on a support and ready for use.
Fig. 2 is a vertical central sectional v1ew of the same, and,
' face u on which is"niounted Fi .B is a plan of the sharpening disk.
Reerring to the drawing by numerals, 10 indicates the sharpening disk made in the present instance of two sheets'of leather 1l andl12 of circular form and ofpdiii'erent diameters and qualities. The lower larger sheet or disk l1, made of a size most suitable and convenient, is preferably a leather having a coarse and somewhat rough sura second sheet a tine grain and con- 12 ma e of leather with 1l, its
centrically disposed, upon the diskJ edge 13 being beveledas shown and spaced from the outer edge 14`of the disk 11 to provide a surface 1'5 for first acting on the razor blades to giv them a rough sharpening, after which the blades are brought to a keen cutting edge upon the upper surface 16 of lthe disk 12."
The sharpening disk 10 may be rotated veniently used is illustrated in the drawing' and as there shown an upright frame 17 is 55 screwed or bolted to a support such las a bench or table 18 and in a bearing 19 formed with said frame 17 is a shaft 20 fixed in said bearlng and projecting horizontally from the front thereof.' Upon the shaft ispmount- 80 edto rotate a beveled gear wheel 21 which may be turned by a handle 22 thereon, said gear wheel meshing -with a small. beveled pinlon 23 on the lower end of a vertical shaft 24 turning in a bearing 25 on the top 65 of the frame 17. The upper end of the shaft 24 is threaded and screwed thereon is a metal plate 26 suflicientlylarge to properly support and uphold the polishing Vdisk 10 which 1s placed upon said shaft 24 passing through the central hole therein and secured in place by a nut 27 andwasher 28 that presses down upon the top or section 12 of thesharpening disk. In use, the razor blade is secured in'a suit- 75 able holder and held first upon the surface 15of the coarse leather disk ll'with one hand while the other hand rotates the gear wheel 21` and the sharpening disk. lhe blade holder being held at a proper ang-loto the blade will be roughly sharpened andL when this disk 11 has brought the blade to a suitable condition the same is transferred to the disk 12 of fine leather where it is given its final whetting and polishing and brought to the desired keenness forshaving.
1. A tool sharpening machine comprising an upright rotatable shaft, a disk clamped at its center on said shaft and 'formed of 90 two super posed concentric sheets of leather of different qualities and diameters, disk being'unsupported at lts edge to permit of flexion ofthe working portion under pressure of the to'ol being sharpened.
2. A tool sharpening machine comprising plate, the end of the 7Q Y shaft below the disk and of smaller diamemem-m an upright otuabe shaft, a; disk mounted edges of the latter are permitted to e at its center on said shaft and formed of a under pressure. 10 lower'sheet of exble Selfsus1ainng learherl In testimony whereof I 'have aixed my unsupported at its edge anda smaller sheet. signature in the presence of two Witnesses. of ner eather mounted concentrically upon WLLAM THOMAS MILLER. the lowex' sheet, and' e meta, plate on the Witnesses:
