SAFETY RAZOR
John E. Drew, Jersey City, N. J., assignor to
Durham Duplex Razor Company, a corpora
tion of New York
Application February 6, 1935, Serial No. 5,178
3 Claims.
(Cl. 30—74.1)
This invention relates to improvements in
safety razors, more particularly to safety razors
of the hoe type.
The main object of the invention is to secure
latter;
5 the blade clamp to the guard in a novel and more
efficient manner. To this end the under face of
clamp;
the clamp may be provided with a longitudinal
recess or well and undercut lugs overhanging the
recess, and the clamp may be retained on the
guard by spring clips passing through a slot or
perforations in the blade and adapted to engage
the undercut lugs of the clamp. Moreover, the
spring clips may be integral with the guard or
?xed in a curved handle, which is permanently
” or detachably secured to the guard, and have
their free ends dovetailed into the clamp so that
the latter may be removed from the guard by
sliding it endwise, and replaced in a similar
manner.
20
A further object of the invention is to permit a
close shave to be obtained with one cutting edge
of the razor and obtain a shave which is not
close, with the other edge.
In pursuance of this
_ object the longitudinal edges of the clamp are of
different thickness to permit the opposite cutting
edges of the razor to be applied to the face at
the required angle for the two different types of
shave.
Another object of the invention is to reversibly
30
secure the clamp to the guard by spring clip-s or
other means which will take up the wear on the
clamp, whereby the two different types of shave
may be obtained with each cutting edge of the
blade.

With these and other objects not speci?cally
mentioned in View, the invention consists in cer
tain constructions and combinations hereinafter
fully described and then speci?cally set forth in
40 the claims hereunto appended.
In the accompanying drawing which forms a
part of this speci?cation and in which like char
acters of reference indicate the same or like

In carrying the invention into effect there is
provided a curved handle, a guard mounted on
the handle, a clamp reversible end-for-end on
said guard, means for interlocking the clamp with
the guard in either position of the clamp, and a
blade held between the guard and the clamp. In
the best constructions contemplated, the guard
is provided with .two oppositely facing spring
clips having mortised ends, and the clamp has
two sets of opposed tenons adapted to interlock
with the mortises on the spring clips in either
position of the clamp on the guard. In the best
constructions, also, the under face of the clamp
has a longitudinal recess and the tenons are
formed by undercut lugs on the side walls of the .»
recess, and the longitudinal edges of the clamp
are of different thickness to permit the cutting
edges of the razor to be applied to the face at
different angles, whereby a close shave may be
obtained with one cutting edge of the blade and
a coarser shave with the other edge.
Referring now to Figs. 1 and 2, the‘ guard l is
permanently or detachably secured to a curved
handle 2 in any suitable manner. The oppositely
facing spring clips 3 may have their ends ?xed
in the handle and project through transverse
slots in the guard, as shown, or may be formed
integrally with the guard.
As shown in Figs. 3 and 4, the guard may be
provided with opposite longitudinal slots 4‘ dis 45
posed to underlie the cutting edges of the blade
when it is clamped thereon, to permit the pas
sage of the soap and hairs removed from the face
by the cutting edges of the blade.
The bars 5,
which form one side of the slot, may have a series
of transverse grooves in order that the soap may
be rinsed therefrom more readily.
Referring to Figs. 9 and 10, it will be seen that
the under face of the clamp B is provided with a
recess or well 1 having opposed pairs of undercut 55
2
2,118,498
lugs on its sides. The free ends of the spring clips
3 are mortised so that they may be brought into
interlocking relation with the tenons formed by
the undercut lugs 8. Since the hooked ends of the
clips face in opposite directions it will be appar
ent that they may be interlocked with the tenons
8 upon inserting them in the well 1 and sliding
the clamp endwise over the guard until the abut
ment 9 of the clamp meets the end of the guard,
and that the clamp is reversible end-for-end on
the guard. By reason of the oppositely facing
arrangement of the spring clips 3 the wear on
the tenons 8 will be taken up, the spring clip
nearest the abutment 9 acting to press the clamp
handle, of a guard mounted on said handle, a
clamp reversible end-for-end on said guard,
means for interlocking said clamp with said
guard in either position of the clamp, and a flat
blade held between said guard and clamp and
provided with cutting edges on its longitudinal
edges, said means including two oppositely fac
ing spring clips having mortised ends projecting
lengthwise along the guard, and two sets of op
posed tenons adapted to slidably interlock with
the mortises on the spring clips upon sliding the
clamp endwise over the guard, the longitudinal
6 down on the guard I while the adjacent set of
edges of the clamp being of different thickness to
permit the cutting edges of the blade to be ap
plied to the face at different angles to obtain a 15
tenons is sliding into interlocking engagement
therewith, and the free end of the other spring
clip ?exing inwardly to permit the other set of
be obtained with both cutting edges of the blade
upon reversing the clamp on the guard.
tenons to freely slide into interlocking engage
ment with the mortises of the spring clip farthest
curved handle, of a rigid, perforated guard
from the abutment 9. It will also be understood
that the blade In which may be ?at and have
a slot or perforations through which the spring
clips project, is thus locked between the guard
and clamp.
'
By referring to Figs. 6, 8, 11, and 12, it will be
observed that the opposite longitudinal edges of
close or coarse shave, whereby a close shave may
2. In a safety razor, the combination with a
mounted on said handle, a rigid clamp reversible
end-for-end on said guard, means for interlock
ing said clamp with said guard in either position
of the clamp, and a perforated blade held be
tween said guard and clamp, a longitudinal re 25
cess being formed in the under face of the clamp,
and said means including two sets of opposed lugs
the clamp are of different thickness to permit
formed on the side walls of said recess and op
the opposite cutting edges of the blade to be ap
plied to the face at different angles, so that
positely facing spring clips fastened in said handle
and having mortised ends projecting longitudi
nally and inwardly through the perforations of
said guard and blade, the lugs being undercut
to provide tenons adapted. to slidably interlock
with the mortised ends of the spring clips.
a close shave may be obtained with one cutting
edge of the blade and a shave which is not so
close with the other edge.
Since the clamp is
reversible on the guard, as shown in Figs. 5 and 7,
a close shave may be obtained with each cutting
edge of the blade, and it is immaterial from
which end of the guard the clamp is moved into
interlocking engagement with the spring clips.
From this it follows that a close shave will always
be obtained by the cutting edge adjacent the
thinner edge of the clamp and a coarser shave
with the cutting edge adjacent the thick edge of
the clamp, which is readily distinguishable from
the thinner edge of the clamp.
What is claimed is:
1. In a safety razor, the combination with a
3. In a safety razor, the combination with a 35
handle, of a rigid perforated guard mounted on
said handle, a perforated blade positioned on said
guard, a pair of yielding members fastened in
said handle and projecting upwardly from the
handle through the said perforations of said 40
guard and blade, and a rigid clamp constructed
and arranged to be interlocked with said mem
bers upon sliding the clamp longitudinally of the
guard.
