1, AUGUST KNIPPENBERG, of Ichtershausen, Thuringen, Germany, Manu-
facturer, do hereby declare the nature of this invention to be as follows:
:-
A hair pin according to my invention is at each of its free ends for a portion of
its length of round cross section while the remainder of its length is wholly or
partially of flattened cross section.
Figs. 1 illustrate one arrangement of hair pin according to my invention in front
elevation and in side elevation.
Fig. 2 is a cross section on the line A-B, Fig. 1 but to a larger scale of one of
the limbs of the hair pin.
Figs. 3 show the lower ends of the two limbs also on a larger scale, the left
hand and central views being front elevations and the other view a side elevation.
As will be seen the wire of which the hair pin is composed is flat except at each
of its two ends a at which it is round. The rounded parts in this example are
very short, but they may be longer if desired. The two extreme ends are rounded
off as shewn clearly in Fig. 2 so as to prevent the skin of the head becoming injured
when the hair pin is placed in the hair.
A hair pin of this kind may have its central part 6 of round section as in Fig. 4,
or, to enable it to be more readily grasped by the fingers, it may be ribbed fluted
or otherwise roughened as at c. Fig. 5 illustrates a complete hair pin with
roughened central part as just described; and Figs. 8 illustrate part of such a hair
pin to a larger scale.
Hair pins according to my invention as above set forth may have their flat or
wide sides d d formed with zig-zags or corrugations e which may extend over the
whole length of each limb or only partially as shown in Figs. 6 and 7 these having
for object to considerably increase the holding power of the hair pin in the hair.
The limbs of hair pins according to my invention may also be bent or curved, as
shown in Fig. 7, for the purpose of conforming more closely to the shape of the
head.
As will be obvious some of my improvements may be used without others.

COMPLETE SPECIFICATION.
Improvements in Hair Pins.
I, AUGUST KNIPPENBERG, of Ichtershausen, Thuringen, Germany, Manu-
facturer, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement :-
A hair pin according to my invention is at each of its ends for a portion of its

page_text: length of round cross section while the remainder of its length is wholly or partially
of flattened cross section, as I will now describe with reference to the drawings
filed with my Provisional Specification, wherein
Figs. 1 illustrate one arrangement of hair pin according to my invention in front
elevation and in side elevation.
Fig. 2 is a cross section on the line A-B of Fig. 1, but to a larger scale, of one
of the limbs of the hair pin.
Figs. 3 show the lower ends of the two limbs also on a larger scale, the left hand
and central views being front elevations and the other view a side elevation.
As will be seen, the wire of which the hair pin is composed is flat except at each
of its two ends a where it is round. The rounded parts in this example are shown
very short, but they may be longer if desired. The two extreme ends are rounded
off as shewn clearly in Fig. 2 so as to prevent the skin of the head being
accidentally injured when the hair pin is placed in the hair. A hair pin of this
kind may have its central part b of round section as shown in Fig. 4, or, to enable
it to be more readily grasped by the fingers, it may be ribbed, fluted or otherwise
roughened. Fig. 5 illustrates a complete hair pin with roughened central part cas
just described; and
Figs. 8 illustrate part of such a hair pin to a larger scale.
Hair pins according to my invention as above set forth may have their flat or
wide sides d d formed with zig-zags or corrugations e which may extend over the
whole length of each limb, or only over part thereof, as shown in Figs. 6 & 7, and
which having for object to considerably increase the holding power of the hair pin
in the hair. The limbs of hair pins according to my invention may also be bent or
curved, as shown in Fig. 7, for the purpose of conforming more closely to the
shape of the head. As will be obvious some of my improvements may be used
without others.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. A hair pin having flattened limbs or side portions and rounded end portions a
substantially as described.
2. A hair-pin having rounded end and central portions a & b and intermediate
flattened portions substantially as described.
3. A hair-pin of the kind specified in Claim 1, having a ribbed fluted or
roughened head or central portion e substantially as described.
4. A hair pin of the kind specified in the preceding claims formed with
corrugations cover the whole or a part of the length of the flat sides d d of the
limbs or side portions of the pin substantially as described.
