6 Claims.
The invention relates to electric hair cutters,
and has for an object to present a hair cutter of
small size, in a form adapted to be conveniently
manipulated by one hand with a minimum of ef
5 fort and without requiring the holding or move
ment of the device in positions awkward for the
operator. It is an aim to present a novelconstruc
tion in the ‘device to enable its more certain
manipulation and accurate cutting action.
10
' A further important aim is to effect improve
~ ‘ ments in the construction and arrangement of the
(Cl. 30-210)
of a frame piece 20, which may also be extended
outwardly from the case and shaped to form the
toothed ?nger bar 23, presently to be described.
The body of the frame piece is offset inwardly,
from the shank 2| in symmetrical relation to the
handle.
The frame piece is formed with a cutter side
smoothly ground to true longitudinal rectilinear
surfaces. Centrally and longitudinally of this
face there is formed a groove 22' extending for 10
full length of the body portion and spaced in
parts in such a device. It is a speci?c aim to en
ward from the inner face of the shank 2| a dis
tance. At one side of this groove thebody of the
frame is shaped as a ?nger bar 23 with ?ngers

There is illustrated a hair cutter comprising a
case ‘Ill adapted to form a handle for the appli
ance, the rear body portion of the case being cy
lindrical, and having a forward portion tapered
to an oblong shape in cross section at its ex
40 tremity. The rear end of the case is closed by a
screw cap or bushing 12 preferably formed of in
“sulatlng material so that electric wires may be
various uses in manipulating the device for cut
ting the hair of a person, and particularly in
indicating the angle at which the plane of the
cutter is disposed with respect to the adjacent
contour of the head. These may also be rested 30’
against the head or neck of the person to steady
the cutter as it is moved forward in cutting the
hair. Also, while the handle is grasped in one
part of the hand, a ?nger or fingers may be ex- '
tended to rest on the project from one or both
prongs toward the head of the person whose hair
is being cut, to regulate the length of the hair
left uncut upon the head.
It is also contemplated that the ends of the
spurs shall be rested against the neck or head of 40
the person whose hair is being cut and used as
both a rest and a lever to move the cutter out
led therethrough safely to the electromagnetic
ward from the head progressively as the cutter
motor of the device.
Secured in the cylindrical portion of the case H!
l’ there is an electromagnet l3 comprising a core
is moved forward in operation. This leverage is
effected by adjusting the prongs flat against the
lower neck portion of the person and then by
piece It having two spaced apart cross channels
I5 therein of suitable dimensions to receive a
' coil of adequate size. The core thus has a central
50 ?eld piece It and two outer end field pieces IT.
The coils 18 of the magnet are energized by
wires l9 from a suitable source led through the
bushing l2 as shown. The core piece is centrally
grooved across its outer side longitudinally of the
66 case, and set in the groove there is the shank 2|
twisting the handle so as to cause the tips of the
prongs to press against the person, the bar is
lifted away from the scalp. This twisting referred
to is such as to rotate the handle on its longi 50
tudinal axis, it will be understood. By making
this twisting progressive as the cutter is moved
upwardly, the proper "shingle” of the hair as de
sired may be accomplished.
A cutter bar 26, is provided, of a suitable form 55

complementary to the ?nger bar, in accordance

ably in the groove 22', and the bar 26 'is'extend
ed inwardly into the case a distance as a plate 28 operatively associated therewith, a bell crank lever
on which the rib 21 is continued. Near the inner mounted to pivot at its middle in the plane of the
,end of the bar 26 a lateral rearwardly extending arms of the lever and provided with an arm
arm 29 is formed therein, stopping short of the ‘initially transverse to the cutter and connected
side of the case Ill. The adjacent faces of the at its extremity to the cutter, said’ lever having a 10
frame are smoothly ?nished in a common plane second arm extended longitudinally of and away
on both sides of the groove, so that the bar and
arm 29 may slide smoothly thereon. A lever 30
is laid on the plate 28 and arm 29 to oscillate
15 thereon.
This lever has a longitudinally slotted
extremity, receiving therein a pin 3| carried on
from the cutter and having an armature thereon I
oscillatable transversely to the longitudinal axis
‘of thecutter and an electromagnet operatively
associated with‘ the armature.

A retainer plate 35 is loosely engaged over the
cutter and lever in‘spaced relation to the ?nger
30 bar, this plate having a ?ange 36 at its forward
edge, engages in a groove formed in the outer face
of the cutter, and the plate 35 has at its rear
edge an inner ?ange 38 resting against the ?ange
piece and ?nger bar at the rear edge. Retaining
35 screws 39 are engaged through the plate 35 ‘and
in the frame piece, small helical springs 40 being
engaged therearound and confined between the
plate 35 and the frame piece. By this means the
. cutter maybe held securely in proper operative
40 relation to the ?nger bar and the springs will
prevent binding of the cover plate on the cutter.
In operatiomthe current supplied through the
_ wires l9 may be taken from any suitable source
of alternating or intermittent current supply.
45 The armature 33 and spring 34 may be so pro
portioned as t‘drespond to normal alterations of
current in a 60 cycle supply, or the circuit may
include an interrupter of lower frequency of in
termission. When the magnet I3 is energized the
50 attraction and movement of the armature causes
the lever 30 to swing longitudinally outward and
bearing on the pivot 3|, the‘cutter-bar is moved
' correspondingly outward. As soon as the current
ceases or reverses, the spring forces the armature
55 outward, producing a reverse movement of the

1931 for Electric hair clipper.
