Referring more particularly to the drawings, it
2o is to be understood at the outset that the pres
ent invention includes certain features disclosed
in our copending applications, namely, for Safety
razors, Serial Number 735,547, filed July 17, 1934.
now Patent No. 2,053,642 dated September 8.
-25 1936, and hereinafter referred to as application
“A”, and for Safety razor, Serial Number 22,520,
filed May 21, 1935, and hereinafter referred to as
,
For instance, the razor is of the general type
30 shown in application “B” in that it has a maga
zine for separate blades and means for succes
sively feeding the blades to the blade seat- and
thence to the proper shaving position. The blade
seat and blade may also be preformed to _assume
3l the curvature, either longitudinally or trans
versely or both, described in application “B”, or
the blade, guard or cover or all may have a more
pronounced curvature or turned down effect
transversely adjacent the shaving edge, as will
40 hereinafter be pointed out with greater particu
larity. The blades may likewise have the same de
gree of flexibility longitudinally and transversely
throughout as described in application “A”.
Moreover, the blades, insofar as the positioning
ß slots, grooves or apertures are concerned are in
terchangeable.
'I‘he magazine razor, itself, is so constructed
that the feeding of blades from the magazine to
the proper shaving position and the ejection of
so the used blade from the razor head are both ac
complished by the simple turning of a knurled
rotatable knob. 'I‘he razor may be said to include
a casing with sections I, 2 and 3, divided by par
titions 4 and l, sections I and 3 having upper
l5 and lower walls 6 and 1 respectively.
Section 2 constitutes the watertight magazine
in which a plurality of blades 3 are shown ar
ranged on their ends. Instead of inserting these
blades separately in the magazine we may pro
l0 vide a blade clip as shown in Figure 3. 'I‘his clip
has an end wall 3 with upper and lower walls
I l and II, slotted to receive a spring leaf I2. The
magazine has a door I3 hinged at I4. When the
door is moved to the position shown in dotted
ß lines the clip full of blades is inserted in the
magazine after the leaf I2 has been removed.
The upper and lower walls I0 and I I »have grooves
Il and I3 to engage projections I'I and I3 on the
partitions 4 and I to properly align the clip as it
70 is placed in the magazine with the wall l towards
the hinged door opening. 'I'he wall 3 has an
aperture I3 to permit the free passage of a plate
23. This plate thus engages the face of the
nearest blade, and under the action of the com
" pression coil spring 2|, forces the blades to the
2| while refilling the magazine. The upper and
lower walls I0 and II are provided with inner
flanges 23 and 24 to form guideways for the
blade ends.
'I'he razor head includes a blade seat 23, guards 10
2'I4 and a cover 28 normally resiliently actuated
to clamp the blade on its seat. The razor head,
as shown _in full lines, is in proper shaving posi
tion. 'I'he razor head includes a hollow tube 23

ferent angles of disposition of razors in relation

thereon is visible through the >glass enclosed
which is movable pivotally and rotatably in the l5
bearing 33 formed in the upper plate 6. Its piv
otal movement is possible by means of the tube
being pivotally connected at 3| to the casing.
The tube also carries an arm 3|' on which is ar
ranged a gear quadrant 32 adapted to mesh with 20
a pinion 33 on the upper end of a rotatable shaft
34 having suitable watertight bearings in parti
tions 4 and 5. A rotation of the shaft 34 in a
counterclockwise direction moves the razor head
pivotally from the position shown in full lines to 25
that shown in dotted lines and a clockwise rota
tion of the shaft correspondingly`- returns the
razor head to its normal shaving position. The
purpose of this pivotal movement is to align the
space 33' indicated in dotted lines with the aper- 30
ture 84 in the partition 4 and consequently in
alignment with the razor blade situated at the
extreme left of the magazine. An upward move
ment of this blade under positive pressure forces
the used blade off and forces the new blade into 35
shaving position. Thus when the razor head is
returned to horizontal position the new blade is in
proper shaving position. The blade shown in
Figures 12 and 13 is provided with an elongated
open end slot 36 to cooperate with a stud 36’ of l0
corresponding width, as shown for instance in
Figures 1, 2 and 22 to 27 inclusive, to properly
position the blade on its seat.
In order to use
this type of blade and seat or the seat 23 of Fig.
20 to which the spring clamp cover 23 is fastened, ‘5
it will be readily realized that in moving the razor l
head from the horizontal to the vertical for
feeding a new blade to the head, the latter must
be rotated 180 degrees. 'I‘his is because the open
end slot of the used blade must be adjacent the 50
opening 84 and adjacent the upper or open end
slot of the new blade so that as the new blade is
fed, the used blade is pushed otf of its seat.
'I'his rotative movement is made possible by
means of the following construction: Secured to 55
the casing is a stationary quadrant gear 33
adapted to mesh with a pinion 39. This pinion is
carried by a shaft 40 which carries the seat 23
and which is rotatably mounted in the tube 23.
As previously described a counterclockwise rota- 60
tion of the pinion 33 causes the head to pivot
from the horizontal to the vertical. Simultane
ous with this movement, the pinion 39, meshing
with quadrant 33, causes the head to rotate clock
wise for 180 degrees. The shaft 40 carries a pawl 05
4I spring pressed outwardly by spring 42 forcing
the pawl 4I to engage with the shoulder 43 on
the- inside of the pinion 33, permitting clock
wise rotation to this extent. A reversal of this
movement is prevented by the disengagement of 70
the pawl 4I as it is forced away from the shoulder
43 on the inside of the pinion 33 as the pinion is
moved in the reverse direction.
The movement ofthe shaft 34 is brought about
by the simple manual rotation of a knurled knob 75

inafter. With such a type of disappearing stud

scribed in our application “A”. Instead ofv hav
ing the blade seat shown fiat as in Figure 2, and
which is shown flat for the purpose of simple
illustration, it may be curved transversely or of 20
any other desired shape. However, in the case
wherea transversely curved blade seat is used
of the conventional type and flexible blades such
of the same thickness as the blade so that it
moves only one blade at a time. Accordingly the
as described in our application “A”, in order to
easily feed such blades to such a curved blade 25
slide should also be of a height at least as great
as the height of section 2 plus the thickness of
walls 4 and 5. Fixed to the slide 52 is a pin 55.
As long as the pin is in engagement with the
seat and clamp cover in the same manner as
as not to obstruct the passage of the blade be
tween the clamp cover and the seat. One methodof doing this is shown in Figures 20 and 21 where

element of the blade seat may take the form of
It will be observed that when blades such as
a member 6| with a leg or legs 62 and 63 extend
are shown in Figures 8 to 11 and 14 to 17, in
ing through the blade seat 26 with enlargements
clusive, are used in such a magazine razor as
64 and 65 to prevent removal. 'I‘he member 6l 55
ours, it will be necessary to ñx the clamp cover
on the exterior of the blade seat in such a way fits in a countersunk portion 66 in the blade
outwardly disposed ends 35 thus permitting free
passage of the blade 8.
However, it is not con
sidered that such an arrangement of the clamp
cover is sufñcient means for positively position
65 ing and maintaining the blade on its seat.
Therefore, we provide such means that will posi
tively seat the blade in propèr shaving position
in relation to the guard, independently of the
guard.
For example, Figure 18 shows a blade
70 seat 26 with a groove 59 to Aaccommodate the
blade shown in Figures 8 and 9. Figure 19
shows a seat 26 with a longitudinal stud 31 to
accommodate the blade shown in Figures 16 and
17.
The stud may also be of a disappearing
75 stud type such as shown at 6| in Figure 28, and
by the springs 61 and 68. These various forms
of cooperating positioning elements of the blades
and blade seats are in no way dependent upon 60
the flexibility or rigidity of the blade nor upon
the longitudinal or ltransverse disposition of the
blade, curved or otherwise, whether preformed
or distorted when clamped in the razor head.
The point is that inasmuch as these features are 65
interchangeable the actual illustration in the
drawings is not burdened with a possible mui
titudinous series of combinations.
Now lin addition to the foregoing discussion
and description it has come to our attention that 70
while some blades and holders do provide for a
limited degree of transverse curvature they do
not provide for a. proper disposition of the shav
ing edge with respect to the surface to be shaved.
For instance as illustrated in Figure 29 the sur

By way of comparison, in
order to dispose the razor blade'cutting edge
16 properly it would be necessary in the case of a
It is to be understood that the rotation of the
head may be dispensed with in the event the co- ~
moderately transversely curved blade to hold the
operating positioning elements of the blade and
handle in the attitude illustrated at B, and in the
case of a straight ilat blade, at the attitude illus
trated at C. To overcome these disadvantages
we propose to so dispose the cutting edge portion
of the blade with respect to its main body por
tion that the handle may be held in the con
venient comfortable attitude shown at D and at
the same time insure the disposition of the blade
so that the cutting edge portion will be substan
tially parallel to the surface and therefore sub
head are of such a nature as to make such a rota
stantially at right angles to the hairs thereon.
The arrangement shown in Figure 22 includes
a blade, blade seat and cover of the conventional
type moderately curved transversely with a con
ventional guard.
For the purpose immediately
previously described we may adopt any of the
arrangements shown in Figures 23 to 27 inclusive
or any other blade shape arrangement which
produces the same result. For instance in Fig
ures 23 to 27 inclusive the blade is preformed to
rigidly maintain the shapes illustrated, the blade
in each case being in proper` shaving relationship
with the guard and protruding a substantial dis
tance past the edge of the clamp cover. In Fig
ure 23 'the guard is turned down providing a
curved surface 31* to conform with the curved
surface 8'* of the blade, the remainder of the
latter being moderately convexly curved trans
versely or any other desirable shape. The illus
tration in Figure 25 conforms to that shown in
lFigure 23 with the exception that the main body
portion is substantially flat transversely. In Fig
ure 26 the main body portion of the blade is mod
erately curvedtransversely while in Figure 27
it is fiat. In both Figures 26 and 27 the edge of
the guard, being abruptly turned down, is pro
vided with an angular surface 31h to conform to
the angular turned down edge 8” of the blade.
ß In Figure 24 the shape of the blade, blade seatand guard are the same as shown in Figure 23.
To accommodate a flexible blade of such type as
described in our copending application “A” and
support the same, however, the clamp cover 28
may be extended to be abruptly downwardly
curved as at 28‘. It obviously follows that the
clamp cover could be extended in any of the
arrangements shown in Figures 25 to 27, inclu
sive, equally as well for supporting flexible blades
in the manner shown for supporting preformed
rigid blades.
In each of the cases shown in Figures 23 to 27,
inclusive, the cutting edge is predeterminedly
abruptly turned down to such an extent that as
70 the user holds the handle at approximately the
angular position shown at D, with respect to the
surface S, Figure 29. the shaving edge of the
blade will be disposed substantially parallel to
the surface S and therefore at right angles to the
hairs.
tion unnecessary. 'I'he modification of the actual
structure shown would involve only the elimina
tion of the stationary quadrant gear of the head. _
Likewise the inclined and convexly curved groove
56 for bending the ñexible blade may be made so
as to be removably installed in the razor for tak
ing care of the flexible blades as described. The
aperture, or more aptly, the slot M may be pre
determinedly formed to correspond to the trans
verse dimensions of the blade, whether the latter
be transversely flat, curved, curved and flat or
angular for different extents of its transverse
dimensions.
