SHAVER AND HAIR BEMOVER
"
Gustav Burgeson, Youngstown, Ohio
Application April 20, 1937, Serial No. 138,036
9 Claims. (CI. 30-43)
The invention relates to a shaver and hair re
mover and more especially to a safety razor.
The primary object of the invention is the pro
vision of a razor of this character, wherein in
5 ter?tted relatively movable cylinders provided
with slots when in motion will sever hairs for
1 shaving and hair removing purposes, the cylin
ders being rotatable reversely to each other in
their inter?tted relationship and also the inner
10 most cylinder ‘is reciprocatory and in this man
ner assures the positive shaving and hair remov
ing operation in the use of the razor.
Another object of the invention is the pro
vision of a‘ razor of this character, wherein the
same is roller acting so that it can be rolled over
the skin for shaving and hair removing purposes
and will not cut the skin during the use thereof
and thus assuring safety against injury while
in use.
20
A further object of the invention is the pro
vision of a razor of this character, which is simple
in its construction, thoroughly reliable and ef
fective in operation, readily and easily handled,
positive in the working thereof, absolutely safe
25 from cutting the skin during shaving or the act
of removing hair from the human body, and in
expensive to manufacture.
With these and other objects in view, the inven
tion consists in the features of construction, com
30 bination and arrangement of parts as will be
hereinafter more fully described, illustrated in
the accompanying drawing, which discloses the
preferred embodiment of the invention and
pointed out in the claims hereunto appended.
In the accompanying drawing:

Figure 1 is an end elevation of a razor con
structed in accordance with the invention.
Figure 2 is an enlarged plan view partly in sec
tion.

Figure 3 is a sectional view taken on the line
3-3 of Figure 2 looking in the direction of the ar
rows; and

Figure 4 is an end elevation of the innermost
cylinder of the razor and removed from the outer
45
cylinder.

sponding parts throughoutthe several views in
the drawing.

Referring to the drawing in detail, A desig
50 nates generally the razor constituting the present
invention and comprises outer and inner cylin
ders l0 and II, respectively, these being formed
with circumferentially arranged elongated slots
|2 adapted to register with each other and such
55 slots in each cylinder are disposed close to each
other so that when the said cylinders are ro
tated in opposite directions in their inter?tted
relation to each other a shearing or cutting action
will be set up for shaving and hair removing pur
poses.
The outer cylinder III, which functions as a
roller in the use of the razor, is of greater length
than the inner cylinder H and has ?tted in any
suitable manner in opposite ends thereof, in
ternal gears l3, while the opposite ends of the 10
inner cylinder II are formed with spokes I4 ex
tending radially from end hubs l5, these being
provided with pinions l6. Interposed between
the gears l3 and the pinions l6 are idling gears
|'|, these being enmeshed with the gears l3 and I‘ _
pinions l6, respectively, so that the outer cylinder
l0 under rolling contact with a surface will drive
the inner cylinder H and these cylinders will
rotate reversely to each other through the gear
connections therebetween.
Bridging the outer cylinder I0 is a yoke frame
I8 in which are removably carried stud journals
l9, these having the hubs l5 Journaled thereon.
‘ Centrally of the frame I8 is a handle 2|), being
?xed thereto in any suitable manner.
The gear lit in one end of the outer cylinder III 25
has formed therewith an annular cam 2| coact
ing with an annular companion cam edge 22 at
the end of the inner cylinder || next thereto so
that on relative rotary movements of the cylin 30
ders l0 and II these will be reciprocated with
respect to each other. In other words, under the
operation of the cams 2| and 22, companion to
each other the inner cylinder- U will be recip
rocated within the outer cylinder Ill. The bear- 35
ing ends 23 of the frame l8 for the stud journals
I8 are outstruck to afford a clearance for the re
ciprocatory movement of the inner cylinder ||,
these stud journals l9 being slidably ?tted in said
bearing ends 23 in addition to the rotatable flt- 40
ting thereof. The gear l3 at the other end of
the outer cylinder is formed with a retaining an
nulus 24 for the inner cylinder II and this an
nulus additionally constitutes a track for leaf
springs 25 suitably fitted with the cylinder ||, 45
the purpose of the springs 25 being for holding
the companion cams 2| and 22 in contact with
each other under reciprocation of the said inner
cylinder ii and the relative reverse rotation of
the outer and inner cylinders with respect to each
other.
The idling gears H are separably journaled
on the yoke frame It and are in meshing engage
ment with the gears l3 and the pinions I6.
