STROPPER FOR RAZORBLDES.

Specification of Letters Patent.

Patented .Tiny e, ieee.

Application filed. October 9, 1908. Serial No. 456,971.

To cZZ whom it 'may concern:

Be it known that we, Hanny GoLnsMiTi-I and SAMUEL WERNER, citizens of t-he United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stroppers for Razor-Blades, of which the following is a specification.

This invention relates to improvements in a device or aipliance to be used for stropping razor-b ades and other instruments which require very sharp edges, and while it is more especially intended for holding` and stropping blades of safety-razors of various makes, yet it is, with slight changes, applicable for use in stropping or sharpening the blades of ordinary razors, or other kinds of blades, and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide a stropper for razor-blades and the ike which shall be simple and inexpensive in construction, strong, durable and efficient in operation, and so made that the stropping or sharpening operation may be successfully and properly performed byl an unskilled erson and without injury to the blade or c anger of cutting the hands of the operator.

Another object of the invention is to rovide a simple and eilicient holder for the blades, to be used in. connection with the rotary stropper, and which forms a part of the invention.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In order to enable others skilled in the art to which our invention pertains, to make and use the same, we will now proceed to describe it, referring to the accompanying drawing, in Which- Figure 1 is a central vertical sectional view through the rotary strop er and frame therefor, showing a razorb ade held in stropping position thereon by means of a blade-holder embodying one of the forms of said holders, Fig. 2 is a fragmental view in elevation of the upper portion of one side of the supporting-frame for the rotary stropper, showing by dotted lines the normal position thereon of one of the blade-holders; Fig. 3 is a plan view of a blade-holder embodying one form of the invention therein; Fig. L1 is a similar view of a bladeeholder, showing a modiiication in. the construction thereof Fig. 5 .is a cross-sectional View thereof taken on line 5 5 of Fig. 4 looking iii the direction indicated by the arrows g Fig. is a plan view of still another modified form of the blade-holder; and Fig. 7 is a crossesectional view thereof taken on line 7-7 of Fig. 6 looking in the direction indicated by the arrows.

Like numerals of reference, refer to correspending parts throughout the different views of the drawing.

The reference numeral 10 designates a cylindrical roller which may be made of any suitable size and material, but usually of wood, and has its eriphery covered or provided with suitabfe stro ping material 11, such as leather. The rol er or rotary strop per 10 is centrally mounted on a shaft 12 which is horizontally `iournaled at its ends in uprights 13 located at each end of a base 14 which uprights and base constitute the supporting-frame for the rotary part of the sti-opper. One end of the shaft 12 is provided with a crank-handle 15 by means of which the roller 10 may be turned. he upper end of each of the uprights 13 of the suportingframe is provided with a horizontally cisposed recess 16 which extends from one of the edges thereof inwardly and has its floor or bottom rounded or downwardly and inwardly curved at its inner portion as is clearly shown at 17 in Figs. 1 and 2 of the drawing. Secured to the upper end of each of the u rights 13 is a spring 18 which are extender over the rounded or cutaway portion 17, and together with said parts produce the recesses 16 which are for the reception and operation of lateral and i'lat enten sions 19 with which the blade-holder is proe vided at each of its ends.

Referring now to Figs. 1 and 3 of the drawing, the blade-holder consists of a flat body portion 20 which is preferably rectangular in shape and of any suitable size and material, and has at each of its ends a llat extension 19 to vlit and operate in the :recesses 16 of the supporting-frame, as before stated. The body 20 is provided on one of its surfaces near one `of its edges with two spaced apart ins 21 to lit in corres ondingly spaced openings 22 in the razor-b ade 23 which is shown in Figs. 1 and 3 of the drawing as being of that type known as the Gillette blade.

Located on the opposite edge of the body 2O is a clamp 211 which is provided. at about the middle of its outer portion with an extension 25 to be used in tilting the holder to the position shown in Fig. 1 during the operation of stropping the blade. This clamp preferably has its free edOes outturned as at 26 to cause it to readily pass over the inner edge of the blade 23, and its members are su'lliciently separated to permit of the reception oi the body 20 and a portion ol the blade 23, yet so as to hold the two firmly together.

ln Figs. 4l and 5 is shown a modification in the construction oi the holder which consists in forming the body portion. 2Oa thereol with lateral extensions 19 at its ends and with a tilting extension. 25 at about the middle of one of' its edges. The lower portion of each end of the body 2Oa in the modii'ication now under consideration is provided with an inturned llange 27 which have their edges spaced a slight distance from the upper surface oi' the body 20a and are inclined toward each other at their lower ends as is clearly shown in Fig. l of the drawing, so that the blade may be inserted downwardly between the two flanges andv body where it will be securely held with its lower edge extended far enough below the lower edge ot the body 2()EL to contact with the stropping material 11 on the roller when tilted for the stropping operation.

ln Figs. 6 and 7 is shown another modi'lication in the construction ol the bladeholder which consists in Aforming the tilting extension 25 and lateral extensions 19 of a single piece, and placing thereon a clamp 245L which is provided with a central opening 28 at the middle oi its upper edge through which the extension 25 is passed. ln this latter construction the parallel members 2Q of the clamp 24;EL are spaced apart sulliciently to permit of the insertion therebetween ol the razor-blade which will be held in such position by means oi the clamping action oi' the members 29 of said clamp.

From the foregoing and by reference to the drawing it will be clearly seen and readily understood that by placing the extensions 1) of any one of the blade-holders above-described within the recesses 16 between the springs 18 and the top oi" the cutaway parts of the uprights 13 the holder will be retained by the action olf-said springs in substantially a horizontal position, as shown by dotted lines in Fig. 2, and so that the blade carried by the holder will be out of contact with the stropping material 11 on the rotary cylinder or roller. Vilhcn it is desired to strop or sharpen the blade the holder may be tilted by means of one hand of the operator to the position shown in Fig. 1 while the rotary stropper may be turned with the other hand applied i cease-5 to the crank-handle 15 on one end of the shalt oi the roller. As the extensions 19 are ilat, it is apparent that they will rock on the rounded portion 17 of the uprights so that their lower edges will extend into the downwardly and inwardly inclined portions of the recesses 16 while their upper edges will rest against the lower surfaces of' the springs 18 as long as tilting pressure is applied to the holder, which may be done by applying` the hand to the tilting extension 25 and bladeclamp or the body of the holder. As soon as the hand is removed from the holder, it is apparent that the springs 18 will press the upper edges of the extensions 19 downwardly, and thus remove the blade from the rotary stropper.

lf it is desired to use the holder shown in Figs. 1 and 3 ci the drawing for other blades than that of the Gillette type or without holes, it is apparent that the holder may be turned over from the position shown in Fig. 1 and the blade placed on the surface thereof opposite that having the pins thereon where it will be held by means oi' the clamp.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters-Patent, is-- 1. The combination with two spaced apart uprights, oi a stropping roller ournaled therebetween, a spring secured on the upper end of each of said uprights and extended slightly above a portion of the upper end of each or the saine, and a blade-holder having at each of its ends an extension adapted to be inserted between the said springs and upper parts of said uprights.

2. rl`he combination with two spaced apart uprights, of a s'tropping roller ournaled therebetween, means to turn the roller, a spring secured on the upper end of each of said uprights and extended slightly above a portion. of the upper end of each of the same, a blade-holder consisting of a body portion having at each oiI its ends an extension adapted to be inserted between the said springs and upper parts of said uprights, and means on the body portion oi the holder to hold a blade in position thereon.

3. T he combination with two spaced apart uprights having their upper ends formed with an inwardly and downwardly inclined cutaway part, a spring secured on the upper end of each of said uprights and extended over said cutaway portions, and a bladeholder having at each of its ends an extension adapted to be inserted between said springs and the upper surfaces of the cutaway part ci the uprights.
