SAFETY RAZOR
George Greenstein, Long Island, N. Y.
Application November 4, 1935, Serial No. 48,067
7 Claims.
The present invention relates to safety razors
and has for its objects the provision of a simple,
inexpensive device in which a wafer blade may
be readily inserted and as readily removed;
5 which may be easily cleaned; which, while Tshaped when in use, may be arranged with the
head and handle in parallel relation for occupance of a minimum of space; which may be
(01. 30-51)
clamp and guard member 12 is provided with
trunnions ll engaged in notches I8 in the end
walls whereby the member I2 is tiltably and
removably engaged in the housing II. This
member at its forward end is provided, in the 5
usual >manner, with a guard portion l9 and a
blade clamping portion 20. The rear portion
‘ii of the member I2 is off-set as at 22.
This
quickly disassembled for thorough cleaning and
10 readily reassembled for use; and in which the
blade is positioned without contact of parts of
the razor with the cutting edge thereof.
The above objects are attained by providing
a head comprising two portions movable in rela-
rear portion is also provided with an opening 23.
The housing I! is preferably provided with 10
a down-reaching member 24 which passes
through the opening 23 and terminates in an
enlarged portion provided with a pivot hole for
the accommodation of a pivot pin 25.
15 tion to each other and separable, if desired, and
pivotally connecting a handle to one of said
portions whereby when the handle is arranged
at right angles to the head, a blade is clamped
between the two portions thereof. When the
2O handle is swung in one direction into parallel
Also engaged on the pin 25 is the upper por- 15
tion 26 of the handle l3 which is bifurcated to
form the cam portions 2'! and 28, the member
24 being positioned therebetween. Said member
24 is also provided With a notch 29 engageable
by a spring-pressed detent 30 housed in the 2g.
handle.
The cam 21 is preferably formed with enlarged
opposed portions 3| arranged transversely of
the axis of the handle, and with a reduced D01‘
tion 32 at the extreme upper end of the handle. 25
The Cam 23 is preferably formed as a 111% en
gageable with the plate l2 at its off-set 22.
In use, the handle is swung to the position
shown in Figure 3, so one of the cam portions
55! engages the under side of the rear portion 2| 30
of the plate l2 and thereby rocks said plate into
the position shown in that ?gure. A blade B
may now be dropped into the gap thus formed
between the housing H and the plate 12, the
rear edge 33 of the blade resting against the 35
inside face of the rear wall IS of the housing.
In this manner, the cutting edge of the blade
is not engaged or contacted by any Portion of
the razor when in use. In order to permit the
blade to come to rest against the wall IS, the 40
blade is provided With a Cut-01111 40 which iS nec
essary to avoid the member 24. The handle is
then swung to the position shown in Figures 1
and 2, the cam lug 28 engaging the under face
of the plate l2 at its off-set to rock the plate 45
about its trunnions so the portion 20 thereof
clamps the blade against the under face of the
housing top I4. The blade is now effectively
positioned in the razor against displacement.
In the above manner, the parts may be again 50
manipulated for the removal or replacement of
a blade.
It will be noted that the cams 21 and 28 at
all times control the movement of the plate
I2, the cam 21 serving to open the head and 55
relation with the head, the two head portions

are separated to free the blade for easy insertion
or removal, and when swung in the other direction, the head portions are brought together
and retain their clamped relation.
The accompanying drawing, which is described
in the following speci?cation, more clearly discloses the various embodiments of the invention
as at present contemplated.
In the drawing:—
Fig. 1 is a front View of a razor constructed
in accordance with this invention as ready for
use.
Fig. 2 is a vertical sectional View as taken
along the line 2-2 of Figure 1.
Fig. 3 is a similar View with the handle swung
at right angles to free the blade.
Fig. 4 is an end elevational View of the razor
shown in Figure 1.
Fig. 5 is a rear view of the razor showing details of the connection between the head and the
handle thereof.
Fig. 6 is a similar view showing the manner
of disengaging the handle from the head.
Fig. 7 is a plan view of a preferred form of
blade.
Fig. 8 is a partial vertical sectional view of
an alternate form of razor head.
In the present form of the invention the razor
comprises a head portion 10 consisting of a
housing H, a clamp and guard member I 2, and
a handle [3 normally arranged at right angles
to the head.
The housing It‘! is preferably formed with a
55 top [4, and walls l5, and a rear wall E6. The
2
2,105,351
retain it open, and the cam 28 serving to close
the head and retain it closed.
The detent 30 insures proper positioning of
the handle during shaving and the off-set 22 in
the plate l2 permits the application of considera
ble clamping pressure by the cam lug 28 since
said plate may ?ex slightly under the force
of this pressure.
'
"2. A razor comprising a head consisting of a
housing and a blade clamping member pivotally
associated therewith, a handle for the razor,
pivotally connected to the housing, and cam
means on the razor handle for positively rock
ing the clamping member into and out of blade
clamping relation with the housing when the
handle is rocked.
The razor structure, as above described, permits
10 of movement of the handle in either direction.
At times it is desirable, however, to store the razor
housing and a blade clamping member pivotally
associated therewith, a handle pivotaliy connect
in a small space. For this purpose, therefore, one
of the cam portions 3| may be omitted as shown
in Figure 5 so the handle l3 may be swung in the
engaging a rear portion of the clamping plate
when the handle is swung in one direction, and
15 direction of the arrow 34 without moving the
clamping plate l2. In this condition, a razor con
taining a blade may be carried, as for instance, in
a convenient coat pocket. When it is desired to
remove the. blade, the handle is swung in the
20 direction of the arrow 35 and the action is as
above described.
Ordinarily, it is su?icient to shake the razor
after washing to free it of excess moisture before
storing. However, at times it is necessary to
thoroughly clean all the razor parts. This is best
accomplished when all the parts comprising the
razor are disassembled.
In the present instance
disassembly of the parts may readily be done by
providing the pivot pin 25 with ?attened portions
35 which adapts said pin. for movement along
the open slot ii'l in the member 24. When the
handle I3 is thus removed, the plate 52 may be
. removed from association with the housing H.
In the form of the invention shown in Figure 8,
35 the head is formed as an integral member com
prising the top wall Ha and the clamp and
guard portion lie resiliently associated so that
normally these portions are spaced (dotted lines)
for the reception of a blade when the handle l3
_ is positioned parallel to the head, and are in
clamped relation as shown when the handle is in
right angled position.
This structure provides
a razor of extreme simplicity and durability which
is quite economical to manufacture.

embodiments of the razor as illustrated, it is ap

leasing relation with the housing.
6. In a razor, a blade clamping head, compris
ing a housing and a blade clamping member
pivotally associated with the housing, a handle 40
arranged substantially at right angles to said
head when a blade is clamped between the hous
ing and the clamping member, and means on the
handle for positively moving the clamping mem
ber and thereby freeing the blade when said 45
handle is moved from the mentioned right angle
parent that immaterial changes in design may
be made by skilled persons without departing
position.

What I claim as new and desire to secure by
Letters Patent, is:
1. A razor comprising a head portion consisting
of pivotally engaged members, and a handle for
55 the razor, pivotally connected to‘ one of said mem
bers, said razor handle being provided with cam
means for positively rocking the other of said
members toward and away from blade clamping
relation when the handle is rocked.
7. In a razor, a housing having a top, rear and
said extension, cam means on said handle en
gaged with the front blade clamping portion
of the mentioned member, and cam means on 55
said handle engaged with the rear portion of said
member, whereby upon movement of the handle
about its pivot, the mentioned member is moved.
