July 15, 1930. H. J. WARNER SUPPORT FOR BLADE HOLDERS Filed Jan. 25, 1928 INVENTOR. I flormJI a1"? 1 1 BY ATTORNEY Patented July 15, 1935 nnirnn srA'rss PATENT OFFICE The present invention relates to asupport for a blade sharpener.

in the stropping of razor blades with a blade holder, such as that shown in Patent No. 1,339,397, to Charles TV. Jones, it may sometimes occur that the device holding the blade will be retracted so far that the blade will be drawn beyond the hone or strop and the edge of the blade injured thereby.

An object of the present invention is to mount a blade holder and blade sharpening member upon a base, said base having guide means for said blade holder.

In order to attain this object, there is provided, in accordance with one feature of the invention, a base of sheet metal formed to support a blade sharpening hone and strop, said base having a guide-way therein to receive a portion of a blade holder used in conjunction therewith to guide and limit the movement of said blade holder.

These and other features of the invention will be more fully brought out in the followlowing description and the accompanylng drawings, wherein:

Figure 1, is a view in perspective of a base made in accordance with the present invention, a combined sharpening hone and strop and a blade holder being shown in position thereon.

Figure 2, is a longitudinal vertical sectional view of the apparatus shown in Figure 1.

Figure 3, is a view in top elevation of the base member, a sharpening hone and strop being indicated in dotted lines; and

Figure 4, is an enlarged vertical, longitudinal, sectional view of the base of the blade holder, showing its engagement with the supporting base.

Referring to the drawings in detail, a blade holder A is of the type described and illustrated in Patent No. 1,408,355, to Charles V. Jones, and assigned to me. holder comprises a bent shank 1 having a transverse support bar 2 connected to the lower end thereof and having a ferrule 3 pivotally connected to said shank to turn freely thereon. A pair of blade gripping jaws 4 and 5 are mounted in said ferrule and are pro- HORACE J. WARNER, or s'r. PAUL, Mrnnnso'm snPron-T non BLADE HOLDERS Application filed January 25, 1928.

clasp. rearwardly.

vided with a sliding clasp 6' by means of which the jaws may be closed to grip a blade 7, as shown in Figures 1 and 2 by sliding the clasp forward, or opened by sliding said In the previous construction of blade sharpener, as shown and described in Patent No. 1,408,355, the bottom surface of the cross bar 2 is made flush so as to rest evenly upon a flat surface, but inthe present instance, the shank 1 is extended through the cross bar 2 and extends below the lower surface thereof, as shown in Figure i. The lower end 8 of the shank is of reduced diameter and is threaded to receive a nut 9, said nut resting upon the shoulder formed by the reduction of diameter of the lower end of the shank 1. The nut 9 is spaced from the bottom of the cross bar 2 a sufficient distance to permit free slidable movement of the extending portion of the shank in a slotted opening 10 cut lengthwise of the base B. The base B is formed of sheet metal with downwardly turned longitudinal edges 11 and 12 to form a support and to space the horizontal portion 13 of the base upwardly from a fiat surface upon which it is intended to be supported. The end 14: of the metal sheet of which the base is formed is bent upwardly, and

lugs

15 and 16 on either side of the base and a lug 17 in the center of the plate 18 are bent upwardly to receive a combined hone and strop C. The hone 18 has a layer 19 of felt The blade or other cushioning material adhesively secured to one face thereof and a piece of strop leather 20 is adhesively secured to the face of the pad 19. The slot 10 is preferably of a length which will permit the blade holder A to clear the hone and strop member C when no blade is mounted in the blade holder, but which will limit the rearward movement of the blade holder when the blade is in position therein to prevent it being carried rearwardly of the strop and hone member 0. This construction is desired, since it permits moving the blade holder clear of the hone for facility in packing, and, at the same time prevents sliding the blade rearwardly 01% the hone or strop when sharpening a blade,

which action might cause in'ury to the edge of the blade being sharpened.

In usin the device, the blade 7 is grip ed between tie jaws 4 and 5 and is then slida 1y moved across the hone or strop, first on one side of the blade, and then on the other, to produce a stropping or honing action. The turning of the blade from one side to the other 1s accomplished manually by means of the swiveled ferrule 3.

I claim:

In a device for sharpening blades; 21 base, an edge treating element mounted thereon, said base showing a slot therein, a blade holdin member comprising a blade holder at one e15 and a threaded extension at the opposite end, a nut on said threaded extension, a laterally extending member adjacent said threaded extension, the nut and laterally extendin member normally maintaining the blade holding member in the slot, whereby the movement of said blade holding member is limited.

In testimony whereof I afiix my signature.
