CHARLES R. NALLE, OF FORT WORTH, TEXAS.
HAIRPIN.Specification of Letters Patent.
Patented July 27,1920.
Application filed September 11, 1919. Serial No. 323,145.
To all whom it may concern:
Be it known that I, CHARLES R. NALLE, a
citizen of the United States, residing at Fort
Worth, in the county of Tarrant and State
5 of Texas, have invented certain new and
useful Improvements in Hairpins, of which
the following is a specification.
This invention relates to new and useful
improvements in hair pins.
10 The object of the invention is to prevent
the accidental displacement or the dislodg-
ment of the pin from the hair of the wearer.
In carrying out the invention it is proposed
to construct the hair pin in such a manner
15 as not to injure the hair of the wearer and
to make the pin so that in inserting it in
the hair only smooth and continuous sur-
faces, free from projections and recesses,
will be presented; the fastening means be-
20 ing brought into operation after the hair
pin is in place.
This invention will be more readily under-
stood from a reading of the following speci-
fication and by reference to the accompany-
25 ing drawings, in which an example of the
invention is shown, and wherein:
Figure 1 is a view showing the fastening
fingers extended,
Fig. 2 is a longitudinal sectional view, the
30 fastening element being withdrawn into the
legs of the pin, and
Fig. 3 is a cross sectional detail on the
line 3-3 of Fig. 1.
In the drawings the numeral 1 designates
35 a tubular member having the general shape
of the ordinary hair pin and made of any
suitable material. At its upper end the
member 1 has apertures 2 registered with the
tubular legs of the member. A yoke shaped
40 operating member 3 is passed through the
apertures 2 and is slidable into the legs of
the member 1. The member 1 has its free
ends open.
Flat spring fingers 4 are attached to the
45 lower ends of the member 3 and extend
within the lower ends of the member 1 when
the member 3 is withdrawn. By pushing
toward the member 1 the fingers 4 are pro-
jected and owing to their resilient nature
50 and natural curvature, said fingers curve
inward toward each other between the legs
of the pin as is shown in Fig. 1. It will beseen that with the parts as shown in Fig. 2
the pin may be retained in the hair .of the
wearer without difficulty as the legs of the 55
member 1 are free from recesses, crimps or
projections which latter have a tendency to
break and injure the hair. By referring to
Fig. 1 it will be seen that after the hair pin
is in place and the fingers extended, said 60
fingers will act as hooks and retain the hair
pin in the hair. By pulling outward on the
member 3 and holding the member 1 the
fingers are drawn into the legs of the mem-
ber 1 so that the hair pin may be easily 65
withdrawn from the hair. The fingers 4
must be made of a suitable i esilient material
and give a curvature which would cause
them to curve toward each other when pro-
jected as in Fig. 1. 70
What I claim, is:
1. A hair pin comprising, a. U-shaped
tubular member having oppositely arranged
legs which are open at their forward ends,
said legs having apertures near their rear 75
ends, a yoke-shaped member mounted to
slide within the tubular legs, and resilient
normally U-shaped fingers secured to the
forwardd ends of the yoke-shaped member
in such a manner that said fingers automati- 80
tally curl into the U-sh ape when projected
forwardly of the open forward ends of the
tubular legs, said U-shaped fingers being
adapted to be retracted into the tubular legs
and to permit of the separation of the U- 85
shaped member and the yoke-shaped mem-
ber.
2. A hair pin comprising, a U-shaped
member having oppositely arranged tubu-
lar legs which are open at their forward 90
ends, and provided with apertures at their
rear ends, and a yoke-shaped member
mounted to slide within the tubular legs
and carrying resilient fingers at their for-
ward ends which, are integral therewith, said 95
resilient fingers being flattened and sub-
stantially U-shaped when projected in ad-
vance of the forward open ends of the tubu-
lar legs, said fingers being adapted to be
retracted within the tubular legs and to per- 100
mit of the separation of the U-shaped mem-
ber and the yoke-shaped member.
In testimony whereof I affix my signature.
