1 Claim.
This invention relates to safety razors, an ob
ject of the invention being to provide a safety
razor having an improved construction and ar
rangement of guard and cap constituting clamp
ing means for a double edged safety razor blade
between them, said parts being capable of adjust
ment so as to accommodate various thicknesses
of blade and permit ñexing of a thin blade and
securely clamping a rigid blade without ilexing
the same.
Another object is to provide an improved con
struction of guard and cap which insures a proper
positioning of the blade and the retention of said
blade in proper position under all conditions.
A further object is to provide a safety razor
of this character which can be readily taken
apart, thoroughly cleaned and reassembled.
With these and other objects in View, the in
vention consists in certain novel features of
construction and combinations and arrange
ments of parts, all of which will be more fully
hereinafter described and pointed out in the
In the accompanying drawing
. Figure 1 is a View in side elevation of my im
proved safety razor with the parts assembled for
Fig. 2 is a view in transverse section through
the center of the head of the razor and a portion
30 of the handle, the rest of the handle being shown
in elevation;
Fig. 3 is a top plan view of the razor shown in
Fig. 1;
Fig. 4 is a view in longitudinal section through
CIJ 5 the center of the head of the razor;
Fig. 5 is a perspective View of the razor cap;
Fig. 6 is a plan View of the bla-de;
Fig. 7 is a perspective view of the guard;
Fig. 8 is a view similar to Fig. 2 showing the
position of the cap and guard with a rigid or
non-flexible blade clamped between them.
My improved safety razor comprises three main
parts, namely, a guard I, a cap 2, and a handle
3. 4 represents a double edged safety razor
blade clamped between the cap 2 and guard I,
and said cap is formed centrally with a screw
(Cl. 30-68)
commonly employed in the art, it is to be noted
that as a matter of fact both the members I and
2 constitute guards as they are provided along
their longitudinal edges with teeth 9. .
The guard I is formed on its upper face at 5
both ends with a pair of spaced lugs IU, and ex
tending from these lugs to the side edges of the
guard are transversely extending webs II, and
between the lugs I Il at the extreme ends of the
guard, recesses I2 are formed in the guard. The
cap 2 is provided in its ends with spaced recesses
I3 to receive the lugs Ill, and between these re~
cesses I3 longitudinally extending bars I4 are
provided which extend beyond the ends of the
cap and at their extremities are provided with
downwardly extending fingers I5 which are
adapted to be positioned in the recesses I2 in
the guard. The blade 4 is of the double edged
type and is provided in its ends with spaced
recesses I6 which receive the lugs I0 of the
guard, and the blade is of such a length that
it i'its nicely between the webs II at the ends
of the guard. In other words, the blade is con
iined and held against lateral or longitudinal
movement relative to the guard and cap'by rea
son of the fact that the lugs I0 project through
the recesses I6 of the blade and the webs II
conñne the ends of the blade and, furthermore,
when the cap is screwed down tightly upon the
blade its bars I4 and fingers I5 resting in the ,
recesses I2 further confine the ends of the blade
so that the blade is incapable of displacement
from its normal proper position relative to the
guard and cap when the parts are properly as
The blade 4 must of course have a central
opening 6, as above deñned, to receive the stud
5 of the guard, and where the blade is a ñexible
one in addition to this opening 6, longitudinal
slots I'I are formed centrally of the blade and
merging into the opening 6. It is to be under
stood, as above stated, that my improved razor
is adapted to clamp not only a flexible type of
blade, which is given an arched ilexed formation
between the cap and guard as shown most clearly
in Fig. 2 of the drawing, but it is also within theV
threaded stud 5 which projects through open
scope of the invention to provide a rigid or non- `
ings 6 in the blade 4 and through an opening
‘I in the guard I and engages internal screw
threads 8 in the tubular handle 3 so that when
flexing blade which is also securely clamped be
the handle is screwed tightly against the guard
the cap 2 will be drawn downward to securely
clamp the blade 4 between the cap and the
guard. While I employ the terms cap and guard
to indicate the parts of the razor head such as
tween the cap and guard as shown in Fig. 8 of
the drawing.
While I have illustrated and described what I
believe to be the preferred embodiment of my
invention, it is obvious that various slight changes
may be made with regard- to the form and ar
rangement of parts without departing from my 55
invention, and hence I do not limit myself to the
precise details set forth but consider myself at
liberty to make such changes and alterations as
fairly fall Within the spirit and scope of the claim.
I claim:
of the guard, the blade and the cap both hav
ing recesses in their ends to receive the webs,
integral bars at the ends of the cap between
the recesses therein, said bars extending beyond
the ends of the cap and adapted to rest between
A razor head including a cap and a guard
the lugs on the guard, fingers at the ends of the
adapted to clamp a blade between them, spaced
lugs integral with the guard at the central por
bars adapted to overlie the ends of the blade
between the cap and guard, said guard having
tions of both ends thereof, webs extending from
10 the lugs to the sides of the guard, the surface
between the lugs being flush with the surface
recesses in its ends receiving the fingers.
