HERBERT JACOBSEN, OF BROWNSVILLE, TEXAS.
HAIR-PIN.Specification of Letters Patent. Patented July 22,1913.
Application iled May 5, 1911. Serial No. 625,128.To all whom it may concern:
Be it known that I, HERBERT JACOBSEN,
a citizen of Denmark, and a resident of
Brownsville, in the county of Cameron and
6 State of Texas, have invented a new and
Improved Hair-Pin, of which the following
is a full, clear, and exact description.
This invention relates to a new and im-
proved hairpin of a type adapted to auto-
10 matically secure itself in position on the
hair.
It has been found in the ordinary hairpin
of the bifurcated type, that when not se-
curely placed in the hair, it is very likely to
16 jar or slip out and get lost. This is exceed-
ingly disagreeable, especially if the hairpin
is of considerable value.
It is therefore an object of this invention
to provide means on the hairpin itself which
20 will automatically engage a portion of the
hair and grip the same, so as to secure the
hairpin in position on the hair without dan-
ger of getting lost. This and further ob-
jects, together with the construction and
25 combination of parts, will be more fully de-
scribed hereinafter and particularly set
forth in the claim.
Reference is to be had to the accompany-
ing drawings forming a part of this speci-
30 fication, in which similar characters of ref-
erence indicate corresponding parts in all
the views, and in which-
Figure 1 is a perspective view of one form
of my device; Fig. 2 is a longitudinal see-
35 tion through the form shown in Fig. 1; Fig.
3 is an extended view of the blank from
which another form of my device is made;
Fig. 4 is a side view in elevation of the sec-
ond form of my device; and Fig. 5 is a top
40 edge view of the form shown in Figs. 3.
and 4.
Referring more particularly to the sepa-
rate parts of this invention as embodied in
the forms shown in the drawings, it will. be
46 seen that in Figs. 1 and 2 is illustrated a
comb 1 of the bifurcated type, having tines
3, the inner edges of which converge toward
each other from the outer point of the tines
toward the points of their connection, where-
50 by the tines will be somewhat tapering,
thereby permitting them to be readily in-
serted in the hair.
For the purpose of securing the pin in
position in the hair, there is provided a grip-
56 ping construction, which in the form illus-trated in Figs. 1 and 2 is shown.as embody-
ing a supplementary bifurcated locking
member 4, having spring tines 5 and 6 cor-
responding to the tines 3 and adapted to co-
operate therewith to grip a portion of the 60
hair between the contacting surfaces and en-
trap the same, so as to secure the pin in po-
sition in the hair. It will be noted in this
form that the spring tines.5 and 6 are arched
at 7, in one direction, and at 8 in the oppo- 65
site direction, so that the ends of the spring
tines, indicated at 9, diverge away from the
tines 3, whereby the hair can readily enter
between the tines 3 and the tines 5 and 6.
In the form shown in Figs. 1 and 2, the 70
hair-entrapping or locking member 4 is
shown as comprising a single sheet of metal
secured in any well known manner to the
body of the hairpin 1, as by means of rivets
10 passing through alined openings in the 75
hairpin and the member 4, and also by pro-
viding a tongue 11 on the member 4, which
is bent or flexed around the bridge or arch
of the pin 1, so as to grip opposite faces of
the pin, and thus further secure the locking 80
member 4 to the pin.
In the form shown in Figs. 3, 4 and 5,
the hair-entrapping or locking member 4
is shown as being formed integral with the
pin 1, and bent over, as clearly illustrated in 85
Fig. 5, so that the tines thereof correspond
to the tines on the pin and cooperate there-
with to entrap a sufficient quantity of hair to
lock the pin in position in the hair. Other-
wise this pin conforms to the form shown in 90
Figs. 1 and. 2.
It will thus be seen that there is provided
a simple and- efficient hairpin, which can be
readily inserted in the hair, and when once
inserted, will grip a portion of the hair, so 95
that it cannot be shaken out or lost in any
way whatsoever.
While I have shown two embodiments
of my invention, I do not wish to be lim-
ited to the specific details thereof, but desire 100
to be protected in various changes, alter-
ations and modifications which may come
within the scope of the appended claim.
Having thus described my invention, I
claim as new and desire to secure by Let- 105
ters Patent:-
The combination with a hairpin, bifur-
cated to form a pair of tines secured inte-
grally together, of a resilient hair-locking or
entrapping member bifurcated to form a 1101,068,244.
