COMPLETE SPECIFICATION. Improvements in or relating to Safety Razors

485,747

We, Paul Lauterjung, of 6, Roonstrasse, Solingen-Merscheid, Germany; Eugen Herkenrath, of 74, Herzogstrasse, Solingen-Merscheid, Germany, and Friedrich Herkenrath, of 2, Roonstrasse, Solingen-Merscheid, Germany, all of German Nationality, do hereby declare the nature of this invention and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement:—

This invention relates to a double cutting safety razor with a handle fixed to the guard plate carrying the blade.

The invention resides in that the blade forced by a backing plate, which may be folded up laterally, against the correspondingly shaped abutment surface of the guard plate is twisted longitudinally, one of the narrow sides of the guard plate being pivoted to a blade spring and the other of the narrow sides of the guard plate being securable on the said blade spring, which is held under tension by the guard plate, has its ends bent downwards and is secured to the underside of the guard plate by means of a flat handle having a hollow interior adapted to house a number of blades.

A constructional form of a safety razor according to the invention is shown in the accompanying drawing, wherein:—

Fig. 1 shows a front elevation;

Fig. 2 shows a side elevation; and

Fig. 3 shows a longitudinal section.

1 represents the guard plate, 2 the backing plate, and 3 the blade of the razor situated therebetween. This blade bears on an abutment surface 9 of the guard plate 1 which latter is provided with studs 11 projecting through the outer perforations in the blade 3 into corresponding recesses in the backing plate and guiding in this way the blade 3 on the abutment surface 9. This surface 9 of the guard plate and the backing plate 2 are constructed in such a manner that the blade 3 when mounted in the razor is twisted longitudinally, 4 represents blade spring lodged in a groove like recess on the underside of the guard plate 1 and secured by means of the flat handle 7 of the razor, which is screwed to the guard plate 1 by means of a screw 6, whereby both ends of the blade spring 4 are kept at a slight distance from the guard plate 1. The handle 7 of the razor is hollow in its interior so as to house a number of blades and closed at its bottom end by a detachable cap 10. One narrow side of the backing plate is pivoted to one end of the blade spring 4 by means of an eye 8. A lever 13 engages the other end of the blade spring 4, tensions both ends of said blade spring, and is pivoted to the backing plate 2 by means of an eye 12 arranged on the other narrow side thereof. On detaching the lever 13 from the blade spring 4 the backing plate may be folded over and the blade 3 may be removed, for instance, for cleaning the razor.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is:—

1. Double cutting safety razor with a handle fixed to the guard plate carrying the blade wherein the blade forced by a backing plate, which may be folded up laterally, against the correspondingly shaped abutment surface of the guard plate is twisted longitudinally, one of the narrow sides of the guard plate being pivoted to a blade spring and the other of the narrow sides of the guard plate being securable on the said blade spring, which is held under tension by the guard plate, has its ends bent downwards and is secured to the underside of the guard plate by means of a flat handle having a hollow interior adapted to house a number of blades.

2. Safety razor as claimed in claim 1, substantially as shown and described.
