Specification of Letters Patent.

Patented July e2, 1913.

To all whom t may concern.'

` Be it known that I, FERDINAND Kino,4 subject of the King of Prussia, residing at Bahnhoftrasse, Herford, German Vhave invented certain new and useful mprovements in Safety-Razors, of which the following is a specification.

This invention relates to certain improvements in safety razors of the type having a thin i'exible blade, and has forits object to provide a construction'wherein the blade will be elestically supported near its cutting edge butheld rigid transversely, and for this purpose the blade is clamped between two strips of' soft rubber or other elastic material preferably of such form that the blade is supported not over its whole surface but only at individual points, thus enabling the cutting edve ofthe blade to beni more easily longitudinally, so as to adapt itself to the skin of the user. v i.

In order that-,the invention may be more clearly understood, reference is made to the accompanying drawings, whereon two cm bodimentsof the invention are illustrated by vvav of example.

lili ure l 1s a sectional view through a doub e-edgedv safety razor constructed according to the present invention and taken substantially on the line AB of Fig. 3. Figr 2 is an inverted plan view ofthe upper strip of elastic material. Fig. 3 is a plan of Fig. I with the upper elastic material, the blade and the backing removed, and Fig. 4 is a side view of the lower strip of elastic material. Fig. 5 is a sectional view show ing the invention as applied to a single` edged safety razor. Fig. 6 is a side view of one of the strips of elastic material employedv in connection withthe razor illus-` trated in Fig. 5, and Fig. 7 is a plan view of the razor shown in Fig. 5.A A

VIn the double-'edged safety razor illustrated in Figs. l to 4t`he razor blade a is' clamped between the guard 0 and backing p between two strips b and c of elastic material, such as soft rubber, the upper strip 7) being concave on its under side, so as to form longitudinal projections d onthe lower side ofthe strip. The upper sideof the strip c is formed convex and provided with recesses c' as shown in Figs. 3 anda, thus forming convex projections f adapted to y support the razor blade a at different points in its length. It will thus be seen that the blade is elastically supported longitudinally on both sides near its cutting edge by the strips of soft rubber, while being clamped rigidly transversely. The blade is thus prevented from vibration in its holder but, at the same time, its cutting edge is capable of adapting itself longitudinally to the skin of the user. Moreover, the recesses e enable the cutting edge of the blade to bend more easily longitudinally, so that it readily adapts itself to any unevenness of the skin.-

Figs. 5, 6 and 7 illustrate the application of my invention to a single-edged safety razor having a reversible thin blade of very' nar row dimensions. The blade g is slotted at its ends at h to receive pins e' projecting from the guard Il: so as to position the blade relaltively to the guard. On both sides ofthe blade g and between the backing Z and guard fl: are narrow elastic strips m of soft rubber or the like,y one or both of which are provided with recesses n at suitable distances apart so that the razor bladeg is only supported atindividual points in order to enable the cutting edge of the blade to bend more readily longitudinally while the blade is clamped rigidly transversely.

5. In a safety razor having a thin narrow flexible blade having a double cutting edge, a backing and guard, and means for reversibly positioning and clamping said blade be tween said backing and guard; strips of elastic material on both sides of said blade and clamped between said backing and guard, said strips supporting the blade near its cutting edge so as to form an elastic support for the cutting edge longitudinally on both sides thereof while rigidly clanzping the blade transversely.
