COMPLETE SPECIFICATION.
Improved Safety-razor.
We, AUGUST KOELLER and HUGO KOELLER of Solingen in the German
Empire, Cutlers, 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 that class of razors that are known as "safety razors,'
and the object of our invention is to provide a razor of this kind which is simple in
construction and in which the blade can be readily adjusted to project more or less
over the guard.
The invention consists in the construction or arrangement of safety-razors, and
the combination of parts and details thereof, hereinafter described.
In the accompanying drawings
Figure 1 represents a perspective view of our improved safety-razor.
Fig. 2 is a vertical transverse sectional view of the same.
Fig. 3 is a rear view and Fig. 4 a front view of the same.
Similar letters of reference indicate corresponding parts.
The casing A is composed of two end plates A', each provided at the upper edge
with an inwardly-bent blade-holding lug A2, the bottom A³, the rear flange A, and
the front A', which parts A1, A2, A³, A and A' are made integral and of a single
piece of metal. The upper edge of the front A' is provided with a number of
inclined slits, forming teeth a, and said teeth are bent on a curved line, so as to
form a comb or guard C, having curved teeth, the upper parts of which are
horizontal or parallel with the base. Near the upper edges of the end pieces A',
the blade-supporting plate D is pivotted by means of end pivots D', made integral
with the supporting plate and projecting through apertures in the end plates. Said
blade-supporting plate is provided on its rear edge with a downwardly-projecting
flange D, from the bottom edge of which a central arm E2 projects towards the
front, which arm rests upon the pointed upper end of a screw E, passed through
the screw-threaded block F', which is held in the upper end of an outwardly-
threaded neck G, projecting from the bottom of the casing A. The screw E is
provided on its lower end with a head E' to permit of turning the same. The
tubular handle H has a screw-threaded upper end that can be screwed on the
neck G. A screw L with a head M is screwed through a threaded aperture in
the back flange D* of the blade-supporting plate, and at its head is provided with a
large shoulder that can bear on the rear edge of the blade S. For inserting this
blade, the screw L is screwed outward as far as possible and the screw E is screwed
downward, so as to permit the blade-holding plate D to swing down. The blade S
is then placed upon said blade-holding plate, in such a manner that it passes under
the holding-prongs A2, and at its front edge rests upon the flat upper portions of
the guard or comb C. The screw L is then tightened, so as to bear against the
rear edge of the blade, and the screw E is adjusted higher or lower, so as to give
the blade the proper inclination and to adjust the same towards the front more or
less. By means of the screws E and L, the blade can thus be adjusted to protect
to a greater or less distance, thus adapting the razor for a more or less close shave.
The inclined teeth of the comb do not interfere with the free action of the blade
and give sufficient passages for the lather into the holder.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
:-
1. The general arrangement or construction of safety-razors substantially as
hereinbefore described and illustrated in and by the drawings.

page_text: 2. In a safety-razor, the combination of a blade-holding casing having a vertical
front plate provided in its upper portion with outwardly-bulging curved teeth
forming part of said plate, the upper portion of said teeth forming a flat rest for
the cutting-edge of the blade, blade-retaining lugs projecting from the upper edges
of the end pieces, a hinged blade-supporting plate having a forwardly projecting
arm at its bottom edge, a blade-holding screw in said plate, a screw in the bottom
neck of the casing and bearing against the arm of the blade-supporting plate
and a handle adapted to be applied on said bottom neck, substantially as described.
3. In a safety razor, the combination with a casing provided with a fixed comb
in front and retaining-lugs at the upper edges of the end pieces, of a pivotted
blade-supporting plate in said casing, which blade-supporting plate is capable of
moving independently of the comb, a blade-retaining screw held in said pivotted
supporting plate, and a separate screw for adjusting said supporting plate, which
separate screw is screwed through the bottom of the casing, substantially as set
forth.
