Referring to the drawing in detail, wherein
unitary cutting assemblies.
It is now customary to provide electrically
driven hair clippers and clippers for giving dry
shaves. Some clippers have cutting assemblies
similar reference characters designate corre
sponding parts throughout-the several views, the
letter C vgenerally indicates the clipper, which
comprises a body portion I. This body portion '
(that is, assemblies of ?xed and movable blades) ' I can be made from any preferred materials and
which may be attached to or detached from the
body portion of the clipper.
One of the primary objects of our invention
is to provide a novel means for connecting the
cutting assembly with the body of the clipper,
whereby a strong and sturdy construction will
15 be had, and whereby different types of cutting
assemblies, such as for hair cutting or dry
shaves, can be quickly and expeditiously con
nected with or detached from said body portion.
Another salient object of our invention is to
provide spaced posts rigidly mounted on the cut
ting assembly for snug insertion in sockets
formed in the body, so that all lateral shifting
of the assembly relative to the body will be pre
vented, and whereby no di?iculty will be encoun
25 tered by the operator in associating the assem
bly with the body.
A further important object of our invention is
the provision of novel means associated with the
in any desired shape, and forms the housing for
the electric drive motor (not shown).
The forward end of the body portion I carries
a head I having an angularly extending lower
face ‘I. Extending into the head 8 is the arma
ture shaft 8 of the motor for rapidly oscillating
the actuating lever 8. This lever 0 extends for
wardly of the head I, for a purpose which will
be later setforth. The lower inclined face ‘I of
the head has formed therein a pair of spaced
sockets ill and Ii, the purpose of which will be
hereinafter more fully set forth.
The cutting assembly It comprises a ?xed
blade I! and a movable-blade l4. 'Ihe movable
blade I4 is resiliently urged toward the station
ary blade i2, and has formed therein a socket
for receiving the forwardly extended end of the NI5
oscillating lever '8. The rear edge of the station
ary cutting blade I! has formed thereon a rear
wardly directed plate It, which is adapted to lie
body for releasably engaging said posts, whereby
accidental displacement of the ‘posts and the as;
close up against a [portion of the inclined face ‘I
sembly from the body will be prevented.
A still further object of our invention is the

with these and other objects in view, the in
vention consists in the novel construction, ar
rangement, and formation of parts, as will be
40 hereinafter more speci?cally described, claimed
and illustrated in the accompanying drawing, in
which drawing:

structed in accordance with our invention, parts
45 thereof being shown broken away and in section
to illustrate structural details.
of upstanding posts or studs ii and II, which
are adapted to be snugly received within the
sockets II and ii.
vAs illustrated, screws I! extend through the
plate l5 and into the studs or posts l1 and It
for ?rmly connecting the posts or studs to the
plate. These screws II and the posts can be
utilized for holding the resilient plate 2| for the
movable blade It in place. If preferred, the
outer ends of the posts can be tapered for facili
tating the insertion of the posts in sockets and
for another purpose, which will also be later set

Arranged within the groove I6 is a releasing le
ver 25. This releasing lever 25 has formed there
in intermediate its ends an opening 26 for the
reception of a holding screw 21, which is threaded
in a socket 28 formed in the head 6. The screw
21 has a loose ?t in the opening 26, whereby the
lever will be free to rock on the said screw.
The sides of the lever have formed thereon‘
inturned wings 29 adjacent to the opening 26,
and these wings engage the head and form a
fulcrum for the lever. The forward end of the
lever extends under the plate I5 between the
studs or posts Ill and II, and by pressing on the
outer end of the lever, the lever will forcibly en
gage the plate of the cutting assembly, and thus
move the posts outwardly of the sockets, releas
ing the same from the spring-pressed pins 22.
20 The rear end of the lever can be provided with an
inwardly directed guide tongue 30 for movement
into a guide socket 3! formed in‘the head ii.
In use of our improved clipper, when it is de
sired to associate a cutting assembly with the
25 body portion of the clipper, it is merely neces
sary to insertthe posts l1 and I8 into the sock
ets l0 and II until the plate ?rmly engages the
inclined face ‘I. The tapered portions of the
studs or posts l1 and I8 permit the ready spring
ing back of the spring-pressed pins 22, and, ob
viously, when the posts are in their fully inserted
position the spring-pressed pins will engage in
the grooves 2| and hold the posts and conse
quently the cutting assembly against accidental
As stated, by merely pressing on the outer end
of the lever 25, the posts can be forced outward
ly of the sockets and past the spring-pressed
By our construction, different types of hair cut
ting assemblies can be readily associated with
the head, and the cutting assemblies can be easily
and quickly cleaned. The studs form an ideal
means for permitting a ?rm connection to be
45 had between the body portion of the clipper and
the cutting assembly.
Obviously, a dry shaver cutting assembly can
be associated with the body 5, and thus the
clipper can be of a universal character and used
50 both for hair cutting and shaving.
Changes in details may be made without de
parting from the spirit or the scope of our inven
tion, but what we claim as new is:
