RAZOR SHARPENER
Leon A. Flinker, Detroit, Mich, assignor of one
fourth to John A. Geismar, Toledo, Ohio
Application April 19, 1934, Serial No. 721,379
19 Claims. (CI. 30-36)
This invention relates to a razor sharpener, and
more particularly to a self-sharpening safety
razor.
The present invention has to do with certain
5 improvements on a safety razor and sharpening
device disclosed in my Patent No. 1,984,338 issued
December 11, 1934. One of the improvement fea
tures has to do with the sharpening block or
sharpening surface, in that I have provided a
10 stone over which the blade is reciprocated at a
?xed angle, such reciprocation over the stone sur
face being the sole sharpening action.
Other features include a novel form of sup
porting and positioning structure, including a
U single means for locking the blade in shaving po
sition and for releasing the blade to allow the
same to automatically assume sharpening posi
tion; this includes the combination between the
supporting and positioning structure and pivotal
mounting of the blade holder whereby mere
pivoting of the blade holderrelative to said sup
porting and positioning structure will release the
blade holder from shaving position or will allow
the same to automatically assume shaving po
sition from sharpening position.
_
Still other features include guiding means, ad
justable for wear, removable, reciprocable guard
structure, adjustability of the razor edge relative
to the guard to adapt the razor to di?erent types
3O of beards, and other features of design and con
struction, and particularly including the mount
ing of the blade holder upon the blade support,
as will be more clearly brought out in the speci?~
cation and claims.

The e?icacy of any razor, regardless of its type,
resides in the ability to have a blade, the edge 20
of which is in the best possible condition for
shaving. To maintain a proper edge on the old
fashioned type of standard razor it has been, and
is, necessary to repeatedly and constantly hone
and strop the blade. Even the best safety razor
blades are not consistent in their degree of sharp
ness or shaving performance. This remains true,
even though various types of honing and stropping
devices have been designed and commercially
used. An important feature of the self-sharpen~ 30
ing razor as embodied in the drawings resides in
the fact that the sharpening surface is a stone
and that such stone and blade holder are so positioned and relatively movable as to produce a
keen edge without stropping.
35
The razor stropper, as shown in the illustrated
embodiment, consists of a holder handle 2, rigidly
supporting a sharpening stone 3 and stone holder
&, as best shown in Figs. 2 and 11, said handle be
ing aperturcd to receive guide members 5 and E5
which guide and support a blade support gen
erally designated l. The blade holder support 1
consists of a horizontally extending and recipro
cable arm 8 and an upstanding arm 8 to which
is pivoted, as at it, a blade holder generally desig~ 45
hated H.
Lug members it struck out from the handle en
gage the guide member 6 with the result that such
lug members i2 may be distorted to take up any
wear between the blade support and the guides.
This blade support 1 is adapted to be positioned
either in the position shown in Fig. l, which is
shaving position, or the position shown in Fig. 1i,
which is the normal sharpening position. The
blade support normally tends to move to the posi
2
2,113,299
tion shown in Fig. 4 because of a spring member
l3, the upper end of which projects through the
blade support, the greater portion of which spring
is contained within the holder handle, and the
lower end of which is normally located and posi~
tioned within an aperture in the base of the
handle, as at M.
The blade holder l l is provided with bifurcated
portions l5 which straddle the upright 9 and are
10 pivoted thereto as at H). A hook It on the blade
holder is adapted to receive one end of a coil
spring I? the other end of the spring being pro
vided with a hook member I8 adapted to project
through the blade support and hooked to the
lower side thereof as at I 9. Normal function of
the spring I? is to move the blade holder H
counterclockwise about the pivot II! when viewed
as shown in the drawings, but when the blade
holder is moved clockwise a considerable distance
so that the spring I‘! passes center at pivot ll),
then the function of the spring willbe to hold
the blade holder in the wide open position, or
that position shown in Fig. 7.
As best shown in Fig. '7, the: blade holder forms
25 a bearing sleeve whereby the blade 20 may be
turned from one side to the other about the blade
holder as an axis.
rf‘he holder 4 for the stone 3 is provided with
rearwardly extending upwardly offset members
30 2| positioned at each end of the holder 4.
As
best shown in Fig. 1, the offset portions of the
rearwardly extending members 2| serve as a look
ing and positioning member for the blade holder
by reason of the fact that it receives a flanged
35 portion 22 of the blade holder. As the spring
13 always tends to move the blade support and
blade holder rearwardly, and inasmuch as the
spring I‘! tends to move the blade holder counter
clockwise, it will be seen that the offset portions
40 of the rearward extensions 2| will serve to posi
tively position the blade in shaving position.
This structure is a very important feature of
applicant’s invention because a portion of the
stone holder contacts directly with the blade
holder and positively positions the same in ?xed
shaving position; no other locking means of any
kind is necessary, thus making for a more com
pact less expensive razor.
In order to move the blade and holder to sharp
iii d,
ening position, it is only necessary for the oper~
ator to press down slightly on the lever extension
23 of the blade holder and just su?icient to raise
the ?ange 22 to clear the offset 25; this is ac
complished as shown in Fig. 2. The entire blade
CA L!
support '1 is automatically moved rearwardly by
the spring it.
Just as soon as the blade holder
is raised to the position shown in Fig. 2, the
thumb or finger may be released so that the blade
holder assumes the position shown in Fig. 3. The
spring l3 will continue to move the blade and
blade holder rearwardly to the position shown in
Fig. 4, at which time the blade is all ready for
sharpening. Now by placing the thumb or ?n
ger against the blade support 7, as best shown in
Fig. 5, the blade may be reciprocated forwardly
and backwardly over the surface of the stone 3.
The extreme rearward edges of the portions 26
will now contact with the ?ange 22 of the holder
when the latter is moved forwardly so that the
70 operator, of necessity, can move the blade only
within the con?nes of the stone and with short
sharpening strokes. Thus the razor may be
given three or four sharpening strokes on one
side, reversed as shown in Fig. 7, and given three
7:5 or four sharpening strokes on the other side, and
this method repeated several times. The short
sharpening stroke over the surface of a stone gives
the blade an unusually keen cutting surface with
out the use of any strop whatsoever. Thus the
member 2! looks the blade holder in shaving
position and limits the stroke of the holder when
sharpening. The blade, instead of being secured
to a base carried by the blade holder l l, as shown
in Fig. 7, may be initially fabricated to provide
a rearwardly extending tapped portion adapted 10
to directly receive a threaded journal, as best
shown in Fig. 1.
A vertically reciprocable guard 24 is carried by
the handle 2 and is provided with guard teeth 25,
as best shown in Figs. 8 and 10. The width be 15
tween the guard teeth has considerable to do with
the type of shave obtained by the razor; the far
ther the teeth are apart the closer the shave. To
accommodate the razor to the type of shave de
sired I have provided pins 26 to serve as guides 20
for the guard member 212 but which are readily
removable to permit the insertion of a new type
of guard, particularly a guard with teeth of a
different type, whereby it is possible to provide a
razor to ?t the individual beard. A bell crank 25
member 2'! is pivotally mounted within the han
dle and is provided with one arm 28 adapted to
fit within a slot within the top guide member 5
and also within a slot formed in the blade support
member 8. The other arm 29 of the bell crank 30
projects through a wall in the handle and within
an aperture formed in the guard plate. When
the blade holder and support is moved forwardly
from the position shown in Fig. 4 t0 the position
shown in Fig. 1, the bell crank 21 will be rotated 35
in a clockwise direction, as shown in the draw
ings, to raise the guard plate 24 to shaving po
sition, which is that shown in Fig. 1, and when
the blade support is moved rearwardly starting
at the position shown in Fig. 3, the bell crank 40
will be moved counterclockwise by the blade sup
port and lower the guard plate to an absolutely
safe position as shown in Figs. 4 to 6, so that
even if the member 2! were not used to limit the
normal sharpening stroke the lowered guard 45
plate would prevent contact between the edge of
the blade and the guard.
To raise the blade in shaving position to dif
ferent heights above the guard teeth 25, I pref
erably insert U-shaped clips 30 around each end
of the guard plate 24, as best shown in Fig. 7.
Each leg of the U-shaped clips will preferably
have a di?erent thickness, or be otherwise fab
ricated, so that by reversing the U-shaped clips
in their position around each end of the guard
plate, they will position the blade to different
heights above the guard teeth.
The stone 3, in its preferred form, preferably
has one surface thereof of ?ne texture and the
other surface of coarse texture. If desired, the
side with the coarse texture may be positioned
upright and the stone slightly shimmed up so
that the blade may be reciprocated back and
forth over the coarse surface to grind back the
bevel; this operation may be repeated every year
or two. The shims may then be removed, the
stone turned over and made ready for normal
sharpening operation at a slightly greater angle
than the grinding back operation, although this
preliminary sharpening angle is relatively small
with respect to the horizontal. To remove the
stone, the bottom of the stone holder is provided
with apertures as at 3| through which a small
tool or match 32 may be inserted, see Fig. 12.
The guides 5 and 6 are preferably duplicate
3,
2,113,299
in construction and of such thickness that they
may be slipped through the apertures in the side
of the handle, so that they assume the position
shown in Fig. 14, the respective ?anges 33 hold
ing the guides in position. After this the guides
may be separated to receive the member 8 and
the pressed out portions l2 slightly distorted to
obtain close sliding contact.
Resuming the operation of the self-sharpening
razor, the operator lifts the blade holder II by
slight pressure on the member 23 just so that the
?ange of the holder clears the locking member
2|. The spring [3 will move the blade support
and blade holder to the position shown in Fig. 4
16 in which position the operator may reciprocate
the blade support and holder back and forth so
that the blade is reciprocated over the surface
of the stone at a ?xed angle. The blade may be
reversed from side to side by moving the blade
20 holder to the extreme position, as shown in Fig.
'7. To return to shaving position from sharpen
ing position it is only necessary to continue the
forward sharpening stroke, as best shown in Fig.
6, wherein the blade holder will be slightly raised
25 to clear the member 2| after which the flange 22
will settle in the locking depression and the
guard plate will be moved upwardly to contact
with and be positioned adjacent the bottom of
the blade.
After cleaning the blade it is desirable that
30
the operator gradually release the blade and
blade holder and return the same to the position
