3_ Claims. (Cl. lib-_43)
This invention relates to electric dry shavers
and more particularly it relates to an electric
dry shaver which is shaped like the ordinary
safety razor and which can be operated in the
di same manner as the ordinary safety razor but

Practically all of the manufacturers of elec
tric dry shavers warn their customers not to 'be
discouraged with the ?lrst results of use since
it frequently takes several weeks and sometimes
months before the new strokes and manipula
tions necessary can be mastered. With the- pres
ent invention no practice is necessary since the
25 device is operated with the same strokes and
manipulations as are used with the ordinary
safety razor.
The present invention is further unlike the
electric Shavers now on the market in that the
30 stationary and movable clipper plates are dis
posed so as to ‘be in full view at all times so that
the operator can see at all times how the razor
shaves with each stroke.

It should already be manifest that one ob
35 ject of the present invention is the provision o-f
an electric dry shaver which can be operated
in the same manner as the usual safety razor
but without the need for soap or the like'. An

'I'he electric dry shaver illustrated inthe draw
ings has a handle 2 which may be of hard rub
ber, “bakelite” or any suitable insulation mate
rial. The handle preferably should- becompar
atively small and narrow so as to 4simulate as 20

handle of the ordinary safety razor. The han
dle houses a small electric motor (not shown)

and which is connected by suitable -mechanism 25

an actuator d which extends upwardly from' a
rectangular well in the upper end of the han- dle 2.
.
Formed as to ñt in the well is a supporting 30
member 6 of metal or the like. The member
'6' may be die-cast or even stamped and, as
shown, has channelled end portions 8 (see Figs.
1 and 5 for example), and topv flange portions
I ñ which extend over the -top `surfaces of the .35
handle 2 on each side of the rectangular well.’
The supporting member has a central opening
for the actuator 4.

40 of an electric dry shaver yso _designed that the
operator can see how the razor shaves' with each
stroke.
‘
Another'object of the invention is to provide
an electric dry shaver in which the moving clip
45 per plate is not covered and is so arranged as
to be easily replaced.
`
Still a further object is to provide a shaver
in which the moving plate is narrower than the
stationary plate and is disposed above the sta
50 tionary plate.
s
Other objects will be apparentfrom the fol
lowing description'and accompanying drawings.
In the drawings:-
‘
Fig. l is an enlarged perspective view of one
55 embodiment of the invention showing only the
upper portion of the shaver to which the inven
tion relates.
Fig. 2 is a similar view with the movable clip
per plate elevated to show the manner in which
60 the stationary plate is secured.
The bases of these supporting posts l2, I2' are
preferably square in cross section and they are
snugly disposed in the channelled end portions
8 of the supporting member 6 to which they `are
secured by suitable means such as by the screws y.
I4 and I6.
_
The outer sides of the supporting posts I2,. I2'
are beveled inwardly towards their upper ends
to permit an inward swinging motion of spring
members generally indicated by the reference 50
numeral I8. These may be secured nearer the
base of the supporting posts I2, I2’ by the~ .
screws I6. The spring members I8 may be of
one piece (not shown) or they may be com
prised of a heavier upper piece _2U of non-spring
metal secured to a lower thin leaf spring piece
22. The purpose of the spring members, as will
be more apparent later, is to aid the` recipro
catory movement of the-,movable clipper plate.
The device utilizes a stationary metal clipper 60
2
n
ari-1,219
v plate 24 and a movable metal clipper plate 26,
the latter being slightly narrower in width. Each
of the plates is provided along its longitudinal
edges with teeth 28, 28’ so that when the mov
able plate blade is reciprocated longitudinally a
clipping or shearing action between the teeth
of the plates iseiiected.
The stationary plate 24 is mounted on the
`>supporting posts l2, ‘2f by means oi' screws 30
as shown in Figs. 2 and 4 most clearly. The
`screws 30 are also used to hold the spring guides
32 in place, the inner ends of the latter being
disposed between the stationary plate and the
supporting posts when the device is assembled.
One of these spring guides 32 is shown in per
spective in Fig. 3. They have a rectangularopen
ing through which the spring members I8 pass
and their'purpose is to limit the outward motionof the spring members. As shown in Fig. 2, for
20 example, the ends of the stationary plate 24
have rectangular recesses 34 to permit greater
movement of the spring member. The station
ary plate 24 also has a central opening 36 through
which the actuator 4 extends.) The opening 36
25 is large enough to permit full reciprocatory
movement of the actuator Il.
~
The movable plate> 2B is disposed above the
'- stationary plate 24. It is reciprocated longitudi
nally by the actuator 4 which may engage a re
30 cess formed in the underside of the movable.
plate. As shown in Fig. 'Z the under side of the
movable plate may be provided with a rectangu
lar ridge 3&3, the actuator Il engaging in the well
bounded thereby;
'
`
The movable plate 2@ is held against the sta
tionary plate `by the ‘if-shaped upper ends of the
spring members'iti, the under edges oi’ the cross
portions oi which engage the upper surfaces of
the movable plate adiacent small rectangular
cut-outs d@ in the ends of the plate (Fig. 2). The
` vertical or upright portion of the T-shaped

than the actuator 4. For example, the recip
rocatory movement may be effected by having a
rotatable shaft on the end of which a pin is ec
centrically disposed. ' This pin enga-ges a slot
or recess in the movable plate.
The device illustrated and described is of sim
ple construction. Since the movable plate is dis
posed above the stationary plate and is not cov
ered by a protecting member, it may be easily
replaced. At the same time it is possible for the l0
operator to usethe device by employing the same
strokes as are customary with an ordinary safety
razor. The operator can see at all times how the
shaving is progressing and obtain an excellent
shave without previous practice.
It is obvious that modiñcatlons of the inven
tion disclosed can be made without departing
from the inventive concept, and I do not intend
to be limited except as’indicated in the following
claims.
