Application filed June 23, 1916. Serial No. 105,333.

.To all whom it may concern:

Be it known that I, BERNHARD TROSKY, a citizen of the United States, and a resident of the city of New Yorlg borough of Brooklyn, county of Kings, and State of New York, have invented a new. and Improved liazor-Stropper, of which the following is a full, clear, and exact description.

This invention relates to a razor stropper of that type comprising a pair of rotatable stropping elements between which is held the blade to be stropped, whereby the edge of the blade is sharpened by the elements acting thereon.

The invention has for its general objects to improve stroppers of this type so as to be reliable and efficient in use, comparatively simple and inexpensive to manufacture and so designed as to be adaptable for various types of safety razor blades.

A more specific object of the invention is the provision of a razor stropper having a novel form of blade holder of that type including two bars which are movable one with respect to the other to provide for the insertion or removal of the blade, the bars being so constructed that blades having slots or apertures can be efiectively held thereon, or blades having reinforced backs can be held with equal facility.

With such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views, Figure 1 is a plan view of the lower half of the stropper; Fig. 2 is a bottom plan View of the upper half; Figs. 3, 4 and 5 are enlarged transverse sections showing different types of razor blades in the stropper; Figs. 6 and 7 are side views of different forms of studs for holding double edged blades in proper relation to the stropping elements.

Referring to the drawing, A designates a casing which is in the form of a box made of upper and lower sections 1 and 2 hingedly connected at 3 so that the upper section 2 is in the form of a cover. In each section of the casing is aframe for supporting the rotatable stropping elements. The frame in the section 1 is composed of end plates 4L and 5 connected by a horizontal bar 6, and in the end plates is journaled a shaft 8 of the stropping element 9. The frame in the cover section 2 consists of end plates 10 and 11 connected by a horizontal bar 12, and in the end plates is journaled the shaft 13 of the upper stropping element 14. On the shafts 8 and 13 are intermeshing gears 15 and 16 whereby the stropping elements are held in fixed relation and move simulta neously. On the shaft 8 is an operating crank 17 whereby the stropping elements can be actuated by one hand while the other hand grips the casing and holds the same closed with a razor blade in position.

The razor blade is clamped between the bars 6' and 12 which constitute a razor holder. The razor holding bars are so designed that blades of different types may be effectively held with their edges in proper relation to the stropping elements.

In Fig. 3 is shown a razor blade B of that type which has a stiffening back Z) formed by a strip of metal doubled over the back edge of the blade. In order to clamp such a blade in place the bars 6 and 12 are formed with longitudinal shoulders 18 and 19, respectively, which engage the front edges 20 of the double back I) of the razor blade B, these shoulders being formed by depressing the bars or recessing them. As there are razor blades on the market with backings b of different sizes, holding springs 21 are provided on the lower bar 6 of the blade holder to engage the rear edge of the blade back, as clearly shown in Fig. 3. The blade B is placed on the lower bar 6 of the holder,

and the back 6 is set into the recesses 22 of the bar 6, and the springs 21 firmly hold the blade against movement back or forth or at right-angles to the axis of the stropping elements. Longitudinal movement of the blade is provided by end abutments or shoulders 23 formed by the walls of the re semis ass whichhave' sites by apertures, thelower bar 6 has spaced threaded I w openings 24 into which are s'c'rewed studs 25 ;to enter the apertures 26 or'slot ofthe blade CB7, as inFig; 4,-and theupper bar 12 of the blade holder hasopenings 27 to receive the studs}- These studs prevent the blade irom-islipping in any direction while the blade is clamped between the portions 28 ofthe'ba rs GailjdlQ, The studs 25havecon the fstuds' 25 mam they'have their threaded shanks 29 eccentricxto the axis of the studs,

soithat'when they'a're' Screwed into place,

asi'show n' in Fig.t 5, thecenter of the blade will be nearer the stropping elements than is the blade Fig; i, whereby the sharp edge of the'blade will be stropped at the 7 right level. It" will thus be seen that the razor holderis suitableior many different 25 V stylesiof blades.

Having thus described my invention, I

Copies e f this patentmay be obtained for claim as new and desire to secure by Let- V ters Patent: 7

" 1/18. razor stropper including a supporting structure, stropping means therein, and

a razor holder on the structure and composed of relatively movable bars, one of the bars having apertures, and studs having eccentricportions fastened in the apertures, said studs cooperatmg with the other bar for clanipinga razor blade 1n cooperative relation with the strapping means.

a 2. A razor stro-pper comprising a casing formed of hingedly connected sections, stropping means in the casing, and a razor blade holder mounted in the casing and composed of coacting bars mounted on the respective sections of the casing, and studs removably mounted on one bar and adapted to extend through the other bar for holding a blade in cooperative relation with the stropping means, said studs having attaching portions removably engaged with the associatedbar, and the said attaching portions being eccentric to the axes of the studs.
