The assembly and operation of the aforemen
tioned shaving device is indeed very simple.
Moreover, the manufacture of the cutting head
consisting of the stationary cutter member l3
erative wall provided with a longitudinal slot in
termediate the width thereof, side and rear walls
each of'uniform thickness, the ?at operative wall
and the movable cutter member I4 is accom .'.being provided with a series of spaced and trans
plished very easily and economically by applying verse slits running across the said operative wall
and extending downwardly into the side walls to
a series of spaced grooving cutters to the opera
form teeth between the said slits, the said teeth
tive walls of the tubular cutter members there
by resulting in the formation of two rows of
having free opposed ends along the longitudinal
10 cutting teeth oppositely disposed of the longi-‘
tudinal openings.
>
In order to assemble the cutting head in chan
nel l2 for operation, the movable cutter I! is
?tted within the stationary cutter l3 so. that
15 ori?ces 28 and I! are in alignment. In such
position, the two cutters are inserted into chan
nel l2 of handle I 0 so that end 20 of actuating
arm l6 penetrates both ori?ces. Lugs 22 and
23 are made to engage ori?ces 20' and 2| situated
20 in the rear wall of stationary cutter I .
The
faces of lugs '22 and 23 form a continuous surface
with the rear wall of stationary cutter l3, there
by permitting reciprocal motion of the movable
cutter i4 within the stationary cutter l3. A set
25 screw 25, having ?rst been elevated from chan
nel l2 to permit insertion of the cutting head, is
now tightened to impinge against the top wall of
the stationary cutter l3, thereby securing the lat
ter ?xedly in place.

In operation, the stationary cutter is pressed
against the skin, so that the teeth lying in the
plane parallel to the rear wall of the cutter
containing ori?ces I 9, 20 and 2|, lie against and
coplanar with the skin. When the cutting head
35 I3, is passed over the skin, the hairs are combed
into the grooves between the teeth I’! by virtue
of the outer corners of the teeth formed by the
intersection of the side containing the spaced
teeth I‘! and the adjacent side walls. Since the‘
40 movable cutter H, which is similar in construction
to cutter l3 except that there are less teeth and
wider resultant grooves, oscillates rapidly within
the stationary cutter, at any given instant a num
ber of grooves in i4 coincide with the grooves in
45 stationary cutter l3.
In this position the hairs
which pass thru the grooves in the stationary cut
ter l3, pass on into the coinciding grooves in mov
able cutter ll. When movable cutter ll con
tinues its movement in a plane at right angles
50 to the axis of the hairs, the grooves in I‘ move
away from the coinciding grooves in i3 and thus
shear the‘ihairs oif between the upper surface
slot and combing corners at the line of meeting
between the operative and side walls, a movable
and tubular cutter member similarly formed of
sheet metal reciproca'bly mounted within the sta
tionary cutter member and similarly provided
with a ?at operative wall having a longitudinal
slot intermediate the width thereof, side and rear
walls each of uniform thickness, the ?at operative
wall being provided with a series of transverse
slits running across the said operative wall and
extending downwardly into the side walls to form
teeth between the said slits, the slits of the mov
able cutter being spaced farther apart than the 20
slits of the stationary cutter member, the teeth
of the movable cutter having free opposed ends
along the longitudinal slot and combing corners
at the line of meeting between the operative and 25
side walls, the slots of both the stationary and
movable cutters being in alignment and being
adapted to afford a double row of cutting teeth, a
handle member to the plane of which the sta
tionary and movable cutter members are mounted 30
at right angles.
2. In a shaving device, a tubular stationary
cutter member formed of sheet metal and being
rectangular in cross section and having a forward
wall provided with a longitudinal slot intermedi
ate the width thereof, side and rear walls each of
uniform thickness, the forward wall being pro
vided with a series of spaced and transverse slits
running across the said forward wall and extend
ing downwardly into the side walls to form teeth
between the said slits, the said teeth having free
opposed ends along the longitudinal slot and
combing corners at the line of meeting between
40
the forward and side walls, a movable and tubu
lar cutter member similarly formed of sheet metal
and being rectangular in cross section and being
reciprocably mounted within the stationary cut
ter member and similarly provided with a for
ward wall having a longitudinal slot intermediate
the width thereof, side and rear walls each ofv
uniform thickness, the forward wall being pro
vided with a series of parallel and spaced trans
the undersurface of teeth l1.‘ verse
slits running across the said forward wall
The depth between the wall containing spaced
teeth I‘! of the stationary cutter and the rear
wall of the movable cutter determines the length
of hair that can be cut'by the cutting head.
Morover, the thickness of the wall of the sta
tionary cutter containing teeth I‘! determines
60 the depth of cut for each hair.
The purpose of the aligned openings is to 'divide
the cutting members into two parts, so as to
have two rows of cutting teeth, one following
closely behind the other, allowing for a shave
and ieshave in one operation.
I wish it understood‘ that minor changes and
variations in the position, integration, material,
conformation and combination and subcombina
tion of parts may all be resorted to without de
parting from the spirit of the invention and with
out departing from the scope of the appended

and movable cutters being in alignment and be
ing adapted to a?'ord a double row of cutting 60
teeth, a handle member to the plane of which
the stationary and movable cutter members are
mounted at right angles.
