PROVISIONAL SPECIFICATION.
An Improved Safety Razor.
I, ERNST SCHARFF, of Frankfort-on-the-Main, in the Empire of Germany, do
hereby declare the nature of this invention to be as follows:-
This invention relates to safety razors, and has for its object to simplify and
improve the construction thereof, and to dispense with the usual clamping springs
and set screws used for holding the razor blade in position, by applying a spring
handle or frame in which the razor blade is mounted to fulfil the same function, the
contrivance being, moreover, constructed in such manner that the blade, with its
guard plate, is held firmly in position while in use and can be folded within the
handle or frame so as to be protected from injury, the blade, moreover, being
readily removable for cleaning and stropping.
The razor blade is fixed beneath end clips upon a toothed guard plate which is
pivoted by end pivots at its rear part in the limbs of a double bifurcated frame, of
steel wire, forming the handle of the contrivance, said guard plate being also pro-
vided with studs which are engaged by hook-shaped catches also formed on the
spring frame whereby the razor blade and guard plate when turned into operative
position are held firmly.
The spring frame or handle is formed with a bow or other shaped arm, which,
when the razor and guard plate are thus turned into operative position, bears
against the back of the razor blade and presses it home into the clips of the guard
plate, without the use of any other clamping springs or set screws, the position of
the blade with regard to the guard plate being by this means rendered constant,
notwithstanding grinding of the blade.
When not in use, the guard plate and blade are turned down on the pivots and
lie between the members of the spring frame or handle in such manner as to be
protected thereby.
In this position the blade may be readily removed for cleaning and stropping.

COMPLETE SPECIFICATION.
An Improved Safety Razor.
I, ERNST SCHARFF of Frankfort-on-the-Main in the Empire of Germany, 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 safety-razors and has for its object to simplify and
improve the construction thereof and to dispense with the usual clamping-springs
and set-screws used for holding the razor blade, the latter being mounted in a spring
frame so constructed that the blade with its guard plate is held firmly in position
while in use, can be folded within the handle or frame so as to be protected from
injury, and be readily removable for cleaning and stropping.
Reference is to be had to the accompanying drawings, forming part of this
Specification, wherein Figures 1 and 2 are side and front elevations of the safety-
razor in position for use, and Figures 3 and 4 are rear and side elevations shewing
it folded up. Figure 1ª is a cross-section, through the razor-blade and guard plate,

page_text: in operative position, and Figure 44 a similar section, in the closed position.
Figures 5 and 6 are front and rear views of the guard plate. The same letters of
reference denote like parts in all the figures.
The razor-blade A is fixed beneath end clips upon a toothed guard plate B
which is pivoted by end pivots.C.at its rear part in the limbs of a double bifurcated
frame of steel wire D, G, of the peculiar form shewn in the drawings, said guard
plate being also provided with studs E which are engaged by hook-shaped catches F
also formed on the spring frame whereby the razor blade A and guard plate B,
when turned into operative position, are held firmly. The spring fraine or handle G
is formed with a bow or other shaped arm D which when the razor and guard plate
are thus turned into operative position bears against the back of the razor-blade A
and presses it home into the end clips of the guard plate without the use of any
other clamping-springs or set-screws, the position of the blade with regard to the
guard plate B being by this means rendered constant, notwithstanding grinding of
the blade. When not in use, the guard-plate and blade are turned down on the
pivots C.and lie between the members of the spring frame or handle, as shewn in
Figures 4 and 44 in such manner as to be protected thereby. In this position, the
blade may be readily removed for cleaning and stropping.
To use the razor, the guard plate B is turned up (together with the razor blade)
upon its pivots C until studs E fall into hooks F in which position it is about per-
pendicular to the plane of the handle G, the back of the razor blade bearing against
the bow D of the frame. The peculiar form of the spring frame and handle by
which the razor blade is held in the position for use or in the folded and protected
position, constitutes one of the essential features of the invention. When the razor
is folded and to be put away, a pin is inserted in the bends F above the back of
the blade to prevent it slipping out, but this pin is omitted from the drawings.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is :
The herein-described razor-blade holder or safey-razor consisting in the com-
bination of the guard plate B provided with end clips to hold the blade and pivoted
in the double bifurcated spring frame G, of substantially the form illustrated,
adapted to engage with and hold the guard plate in operative position and to press
the razor-blade into its seat without the use of set-screws or springs as described
and to admit of the guard plate and blade being folded between, and protected by,
the two members of the U-shaped frame G, substantially as specified.
