This invention relates to hairpins or clips and roughened or corrugated surface, see Fig. 3, which
especially that type used upon bobbed hair or secures the pin against lengthwise removal from

the hair. The ?attened portions 3a and 4a, on
There is a considerable variety of hairpins or
clips in use at the present time which are intended
or especially constructed for use upon bobbed
hair. All of them employ a pair of resilient leg
members connected at one end by a loop or eye,
10 the leg members being crimped, corrugated, or
otherwise roughened throughout a portion of their
length to clip the hair placed between them.
Surfaces of this character clip the hair in one
direction only; that is, it resists longitudinal re
moval of the pin from the strands of hair clasped
‘’ between the legs but these surfaces do not satis
factorily secure the pin against lateral removal,
or in other words from working loose by slipping
in a direction longitudinal of the strands of hair
(,0 and, as such, are not altogether satisfactory.
The object of the present invention is generally
to improve the construction and operation of pins
of the character described, and more speci?cally
to provide a pin which not only clips against lon
gitudinal removal but also against lateral move
25 ment in either direction.
A pin having the above characteristics is shown
by way of illustration in the accompanying draw
ing, in which
Fig. l is a perspective view of the pin;
Fig. 2 is a diagrammatic enlarged plan view of
a portion of the pin; and
Fig. 3 is a side elevation of the pin.
Referring to the drawing in detail, and partic
ularly Fig. 1, a hairpin is illustrated which is
3 made of a resilient material, such as spring steel,
or the like. This material is cut in suitable
lengths and bent midway to form a loop or eye
2 and a pair of leg members ,3 and Q, the leg 3
being slightly shorter and bent at its outer end
to permit it to be readily opened when the pin
is to be applied to the hair.
Wire, which is round in cross section, is em
ployed in the manufacture of the pin.
This wire
is fed between a pair of rollers to which sufficient
45 pressure is applied to ?atten or partially ?atten
it as it is fed between the rolls.
In the present
instance portions of the peripheral surfaces of
the other hand, form widened portions length
wise of the legs and these widened portions, to
gether with the narrow un?attened portions 3b
and 4b form undulations or corrugations in the
opposite side edges of the legs, which also tend to
resist lengthwise removal of the pin, but in addi
tion produces another function, to-wit, that of 10
securing the pin against lateral movement or in
other words movement lengthwise of the strands
of hair upon which they are clipped. I
The resistance of the pin against lateral move
ment can be plainly seen in Fig. 2, in which the
lines 5 indicate strands of hair. The ?attened
or widened portions 3a tend to spread the hair
While the narrow portions 31) cause compacting
of the hair. This compacting of the hair resists
tendency of the pin to move laterally in the di 20
rection of arrows at and b, or in other words lon
gitudinally of the strands of hair, and as the cor
rugations formed by the narrowed portions 3b
and 4b resist longitudinal movement of the pin,
or in other words crosswise of the hair, an eni
cient grip between the pin and hair, both lon
gitudinally and laterally, is insured.
While a speci?c form of the pin is shown, it
will be understood that varying changes may be
resorted to within the scope of the appended
claims. Similarly, while both legs are shown as
provided with expanded and narrowed portions
throughout a portion of their length, one leg
only may be so formed, the important feature
being the provision of means on the opposite 35
side edges of the legs of the pin to resist lateral
Having thus described my invention, what Iv
claim and desire to secure by Letters Patent is:— 40
1. In a hairpin of the character described a
pair of resiliently connected leg members, adapt
ed to contact each other, said legs having alter
nately arranged expanded and narrowed portions
throughout a portion of their length to form
undulating side edges and said undulations being
staggered with relation to each other.
the rollers are indented or slightly relieved at
2. In a hairpin of the character described a
spaced intervals, causing portions of the wire to
50 'be fully flattened and other portions only par
tially so. The portion, for instance forming the
eye 2, is only partially ?attened and as such leaves
a thickened portion retaining substantially all of
the spring action of the wire; this being desirable
as the spring action of the wire is largely depend
ed upon to impart clamping action to the legs.
The portions of the legs, indicated at 311 and
4a,, are fully ?attened while the portions 312 and
412 between them remain substantially un?at
60 tened. These un?attened portions produce a
pair of resiliently connected leg members adapted
to contact each other said legs having alternately
arranged expanded and narrowed portions
throughout a portion of their length to form un
dulating side edges said undulations being stag
gered with relation to each other to resist longi
tudinal movement of the legs upon a strand of
hair and corrugations between their contacting
faces to grip a strand of hair and resist move
ment of the legs crosswise of a strand of hair.
