'TOOL' FOR SURFACING RAZOR-STROPS.

SPECIFICATION forming part of Letters Patent No. 712,811, dated November 4, 1902.

Application tied July 5, 1902. serai No. 115,340. (No model.) i

taken in connection -with the accompanying` drawings,is a full,clear, and exact description.

This invention relatesI to the class of tools which are employed for applying to the surfaces of razor-strops a coating which expedites the operation of sharpening razors thereon and serves to produce a keener and finer edge on the razor.

The object of this invention is to provide a tool of the aforesaid class'which shall be more efficient and convenient in its operation and capable of being readily repaired or adjusted to be supplied with different surfacing material; and to that end'the invention consists in the novel construction of the tool hereinafter described, and set fort-h iu the claims.

In the annexed drawings, Figure l is a side view of a tool embodying my invention. Fig. 2 is a longitudinal section of said tool, and Fig. 3 is a transverse section on line X yX in Fig. l.

a represents the handle of the tool. The upper end of thishandle has firmly secured to it a plate b, disposed at right angles to the axis of the handle and provided with a central perforation o and with perforations c'. c at opposite sides of the center.

d d represent the strop-surfacingbars,which are disposed parallel side by side and are each composed of material of a different degree of hardness-7l. e., one maybe composed of Zinc and the other of lead or other suitable material. The softer of said bars is designed to apply anabrading-surface to the razor-strop by rubbing the said bar upon the strop. The bar of the harder material is to be subsequently employed in a similar manner to smoothen said abrading-surface on the strop, or both bars may be used simultaneously. The said surfacing-bars d d are secured at one end1 to the handle by means of studs e e,

projecting from the ends of the bars and in-" serted into the perforations o' c' in the plate b. Through the central perforation c of said plate projects a tie-rod f, which is firmly secured in the handle a and passes between the `bal's d d and has its free end screw-threaded and extending beyond the adjacent ends of the bars d d. A cap gis provided with a peri foration h in its center and with perforations h h' at opposite sides of said center. Through the central perforation protrudes the end of 'the tie-rod f, while the studs e e on the ends of the bars d d enter into the perforations h h'.' Said cap thus fastens the free ends of the bars d d to the tie-rodf. A nut n, applied to the protruding end of the tie-rod and bearing on the capg, serves to confine the said cap in its engaging position.

The surfacing-bars cl cl may be of the form of cylindrical tubes having stay-rods passing longitudinally throughthem and protruding through the ends thereof to form the aforesaid studs e e. Grooves'itin the sides of the bars CZ d, engagingthe tie-rod f, prevent said bars from turning.

The described construction of the surfacing-tool allows the surfacing-bars d d to be readily removed for repairs or renewal when required, said removal merely requiring the nut 'n to be unscrewed from the tie-rod fand the cap g to be stripped from said rod. This allows the bars d d to be drawn out of engagement with the plate b.

What I claim as my invention isl. The improved tool for surfacing razorstrops, which consists of a plurality of surfacing-bars disposed sideV by side and each composed of a strop-surfacing material of a different degree of hardness, a handle secured to one end of the joined bars, a tie extending from the handle to the free ends of the bars, and a cap securing said ends of the bars to the tie as set forth.

2. A tool Y'for surfacing razor-strops, consisting of a plurality of bars disposed side by side andforined with transversely-rounded faces and each composed of strop-surfacing lmaterial of a different degree of hardness, a

handle secured to one end of the joined bars,- a tie-rod extending from the handle and pass= ing between the said bars, and a cap tying the free ends of the bars to the said rod as set forth.

3. A tool for surfacing razor-strops, conprovided with a plurality of perforations, a tie-rod fastened to the handle and projecting through the central perforation of the plate, surfacing-bars disposed parallel' at opposite sides of the tie-rod and provided with studs inserted in perforations of the aforesaid plate, a cap having perforations receiving the end of the tie-rod and adjacent studs of the surfacing-bars, and a nut on the protruding end of the tie-rod confining the cap in its engagement as set forth.

4. A tool for surfacing razor-strops, consisting of a plurality of tubes disposed side by side and each composed of metal of a dif-
