forming to the conñguration of the blade and
head plate. The blade clamp 30 may be struck
from a single sheet of spring metal having a for
15 mation in blank as shown in Figure 4. The clamp
30 is formed with a ilat clamping plate 3| having
a straight front edge 32 extending thruout its
length, and a straight rear edge 33 from each
end of which the clamping plate is cut out on
arcs as at 34 to provide relatively narrow end
portions at each end of the clamping plate hav
ing a Width slightly less than the width of the
reduced end of the blade 22. Bent to extend for
wardly in spaced relation over the rear face of
25 the clamping plate 3| just beyond each end of
the straight rear edge 33 are clamping fingers 35
for yieldably engaging the rear face of the head
plate I8 at opposite sides of the notched out por

30 33 of the clamping plate is a shallow stop ilange
36 against which the straight rear edge 25 of the
blade 22 abuts. This downturned stop flange 36
as will be observed in Figure 2 has a width sub
stantially equal to the thickness of the blade 22.
Downturned along each arcuate edge 34 of the
blade clamp are ñanges 31 which have a depth
preferably equal to the combined thicknesses of
the blade 22 and head plate I8, and these flanges
31 form abutments for the arcuate edges 26 of
40 the blade. The arcuate flanges 31 have the clamp
ing fingers 35 extending forwardly from the lower
edges thereof, and these arcuate ñanges also as
sist in guiding the blade into a properly centered
position longitudinally of the blade clamp and
45 also prevent longitudinal shifting of the blade
when clamped upon the head plate. The speciñc

between one’s thumb and foreñnger so that
the blade and blade clamp may be removed as a
unit and without liability of contacting the blade
cutting edge 23.
Thus it will be seen that a safety razor of irn
25
proved construction has been provided wherein
the blade carrying head is mounted in a free
floating relation to the handle portion to permit
the blade to automatically follow the curvatures
of the face as well as yield in directions toward 30
and from the handle during use. It will further
be apparent that a specific construction of the
blade has been provided permitting better use of
the razor when shaving around one’s nose.
Changes in detail may be made to the form of
invention herein shown and described, without
departing from the spirit of the invention or the
scope of the following claims.
I claim:
l. A safety razor comprising a handle portion, 40
a head movably mounted in the handle portion,
and yieldable coupling means between the han
dle portion and head to permit rotary yielding of
the head about a fixed axis and straight line lon
gitudinal movement with respect to the handle 4:5
portion.
2. In a safety razor, a handle, a stem rotatable
blade during use.
In use of the safety razor it will be noted that
and axially movable in the handle, a head carried
by one end of the stem, and yieldable coupling
means between the stem and handle and placed 50
under tension upon movement of the stem from its
position as normally held by the yieldable cou
due to the yieldable coupling between the stem
I2 and handle portion A, that the blade carrying
pling means.
3. In a safety razor, a hollow handle, a stem
50 also provide for better sight at the ends of the
55 head plate has a free floating movement and is
permitted to yield in directions axially of the
handle portion as well as rotate therein.
Refer
ring particularly to Figure 2 it will be seen that
the head plate may move away from the handle
60 portion by extending the coil spring I5. Due to
the convolutions of the coil spring I5 being nor
mally spaced apart when the spring is not under
any tension, the head plate may move toward the
handle portion by compressing the coil spring.
Outward limited movement of the stem I2 is pro
vided by engagement of the coil spring with the
inner end of the guide bushing 9, while inward
movement of the stem will be limited by contact
ing of the convolutions of the coil spring. The
70 coil spring I5 when in its normal condition yield
ably holds the head plate in one position until an
uneven pressure is exerted upon the end portions
of the head plate whereby the head plate will be
slightly twisted to one side or the other as shown
75 in Figure 3 and place a rotary or twisting tension
axially movable in the handle, a blade supporting 55
head carried by one end of the stem, and cou
pling means between the handle and stem and
normally retaining the stem in a position relative
to the handle permitting limited yielding of the
stem axially in either direction from its normal 60
position of rest.
4. In a safety razor, a hollow handle, a stem
rotatable and longitudinally movable in the han
dle, a blade carrying head mounted transversely
of one end of the stem, and spring means con
nected between the handle and stem and per
mitting rotary and longitudinal movement of the
stem within the handle in either direction from
its normal position of rest.
70
5. In a safety razor, a hollow handle, a stem
rotatable and longitudinally movable in the han
dle, a blade supporting head mounted transverse
ly of one end of the stem, and a coil spring
encircling the stem within the handle and having 75
2,059,172
one end rigid with the handle and its opposite
end rigid with the stem.
6. In a safety razor, a handle, a stem rotatable
and longitudinally movable in the handle, a coil
spring encircling the stern, means rigidly con
necting one end of the spring to the handle, and
means rigidly connecting the opposite end of the
spring to said stem whereby the spring is placed
under tension by either rotary or longitudinal
10 movement of the stem.
‘
'7. In a safety razor, a hollow handle, a cylin
drical stem rotatable and longitudinally movable
in the handle, a blade supporting head mounted
to extend transversely of one end of the stem,
15 a coil spring encircling the stem within the
handle and having the convolutions thereof nor
mally spaced apart, means rigidly securing the
spring atone end to the handle, and means rig
idly securing the opposite end of the spring to
20 the stern.
8. In a safety razor, a handle embodying a
tubular casing, a plug secured in the rear end of
the casing and having an axially disposed bore,
a guide bushing secured in the forward end of
25 the casing and having a bo-re axially aligning
with the bore in said plug, a stem reciprocable
and rotatable in said bores, a blade supporting
head mounted transversely of one end of the stem,
and a coil spring encircling the stem between the
plug and guide bushing and having one end rig
idly secured to said plug and its opposite end
rigidly secured to the stem for exerting a tension
thereon when said head is moved from its normal
position at rest.
35
_
9. In a safety razor, a handle comprising a
tubular casing, a plug fixed in the rear end of
the casing and having a bore extending axially of
the casing, a guide bushing ñxed in the forward
end of the casing and having a bore axially
aligned with the bore in said plug, a stem ex
40
tending axially thru the casing and having its
inner end rotatably fitting in the bore of said
3
plug, a sleeve fixed to the stem and slidably fit
ting in the bore of the guide bushing, a blade
carrying head mounted transversely of the outer
end of the stem, a coil spring encircling the stem
between the plug and guide bushing, means rig
idly connecting the spring at one end to the
plug, and means rigidly connecting the opposite
end of the spring to said sleeve, said spring hav
ing the convolutions thereof normally spaced
apart.
10. In a safety razor, a handle, a stem yieldably
mounted in the handle, a head plate mounted
midway of its ends upon the outer end of the
stem and having its rear portion cut away at each
end of the plate providing relatively narrow end
portions, a blade for engaging over the front
face of the head plate and substantially con
forming to the shape thereof, and a blade clamp
embodying a clamping plate engaging over the
‘blade and clamping fingers engaging the rear 20
face of the head plate at opposite sides of its
point of connection with said stem, said blade
clamp having ñanges along its rear edge and be
ing of a shape substantially conforming to said
head plate.
25
11. In a safety razor, a head plate having a
recess in its rear edge intermediate the ends of
the plate and cut away on arcs at each side of
the recess to form relatively narrow ends for the
head plate, a blade having a central portion pro 30
vided with a straight rear edge and cut away
on arcs from each end of the straight rear edge
to pro-Vide substantially narrow end portions for
the blade, and a clamp for securing the blade to
the head plate embodying a flat clamping plate
for engaging the blade and clamping ñngers for
engaging beneath the head plate, said recess in
the head plate permitting grasping of the rear
central portions of the blade and blade clamp for
removal thereof from the head plate.
