I. HENRY LADD CARPENTER of 26 and 28 Washington Avenue, Minneapolis
Minnesota, U.S.A. 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 :-
My invention relates to hat pins or fasteners for ladies hats, and the object of
the invention is to provide a hat pin which may be permanently secured in the
hat and which need not be removed from either side thereof in order to secure
the hat to the head, thereby avoiding all puncturing and disfiguring of the crown
of the hat.
My invention consists in a fastener or pin adapted to be secured in a hat
with its ends projecting through the opposite sides thereof, the middle portion of
said pin being provided with outwardly extending fingers, which, when the pin is
rotated, catch and hold the hair and thus firmly secure the hat in place.
Further my invention consists in the combination with the pin proper or shaft,
of curved fingers and of fingers of different lengths to conform to the shape of
the crown of the head; further my invention consists in means for locking the pin
or shaft to prevent rotation thereof thus loosening the fingers or prongs; and
further my invention consists in the combination of removable ornamental outer ends
for the pin, and in further details of construction and in combinations, all as herein-
after described and particularly pointed out in the claims.
The invention will be more readily understood by reference to the accompanyings
forming part of this Specification, and in which ;
Fig. 1 is a sectional view of a hat showing a hat fastener embodying my invention
in place therein.
Fig. 2 is au enlarged view of the hat fastener with the ornamental ends
removed.
Fig. 3 is an end view taken from Fig. 2.
Fig. 4 is a still further enlarged detail showing the manner of securing the head
upon the pin or shaft.
Fig. 5 is a similar view showing the opposite removable end, and also showing the
locking device in section.
Fig. 6 is a sectional view on the line
of Fig. 5.
Fig. 7 shows the parts of Fig. 5 in full lines.
Fig. 8 and 9 are respectively transverse, and longitudinal sections of a modified
form of locking device.
As shown in the drawings, 2 represents the pin or shaft proper, having the
square end-portions 3 and 4, which are preferably notched or serrated to form
the small rat het racks 5 thereon, these square ends are adapted to hold the
ornamental ends of the pin, which alone shows from the outside. The head 6
may be of any design desired, and is provided with a square socket 7 to receive
the end of the shatt. The head carries a small spring 8 adapted to engage the
teeth on the end of the shaft, and the spring is so arranged that the point of a knife
may be inserted under the spring to lift it out of engagement with the teeth, when
the head may be slipped off. As pressure is exerted on the pin through the
head, the end of the shaft is preferably slipped clear into the socket of the head
so that the pressure on the head need not be carried on the light spring 8.
The scabbard 9 which conceals the other end of the pin is similarly secured in
place.

page_text: The middle portion of the pin is occupied by a series of depending prongs or
fingers 10 which are preferably curved, as best shown in Fig. 3, and diminish in
length towards the middle of the pin, the lower ends of the fingers or prongs
projecting into the arc of a circle substantially corresponding to the crown of the
head. The points of the fingers are rounded but not sharp. The fingers are
preferably arranged parallel to one another, but if desired may be irregularly
arranged to ensure their catching in the hair of the wearer.
When the hat is first put on the fingers are turned to project downward towards
the head, then the pin is turned to raise the fingers or prongs upwardly and thus
pass them through the hair. This catches or forms in loops thereon and securely
retains the fingers or prongs. The pin or shaft preferably passes through both
sides of the hat and through the small metal plates 11 and 12 sewed to the inner
side thereof.
One of the plates is provided with a locking device to engage the square part of
the pin and to prevent the same from rotating backwardly and thus releasing the
pin. This locking device is preferably constructed so that a slight inward push
upon the head of the pin will release the lock and permit the free backward
rotation of the pin.
The detail construction of this locking device is illustrated in Figs. 5, 6, and 7.
The small boss or casing 13, which is provided on the plate or button 12, contains
the small coiled spring 14 adapted to press against the two small ratchet disks 15
and 16. The latter disk is secured in the end of the casing 13, while the former
is secured upon the square part of the pin, next to the shoulder thereof. A positive
movement of the pin is permitted by the teeth of the two ratchets slipping by one
another, while the pin or shaft may be rotated backwardly only after pushing
the pin back far enough to move the ratchet 15 out of engagement with the
ratchet 16. This lock may be replaced by many others quite as good. A cheaper
construction thereof is shown in Figs. 8 and 9, where the casing is shorter and
contains simple flat bow-springs 18 which embrace the sides of the square portion
of the shaft.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;
1. A hat fastener, comprising the shaft, provided at its ends with means for
rotatably securing it to the opposite sides of a hat crown, and between its ends with
a series of laterally projecting fingers substantially as described
2. A hat fastener, comprising a shaft or wire provided at its ends with means for
rotatably securing the same to the opposite sides of a hat crown, and also
provided between its ends with a series of laterally projecting fingers, and
a locking mechanism to prevent backward rotation of said shaft, substantially as
described.
3. A hat fastener, comprising a shaft, having its ends loosely secured on the
opposite sides of the hat crown, removable means arranged on the end of said shaft
for rotating the same, said shaft being provided between its ends with a series of
curved laterally projecting fingers, substantially as described.
4. A hat fastener, comprising a shaft, having its ends rotatably secured in the
opposite sides of a hat crown, and a series of curved fingers projecting laterally
from said shaft between its ends and said fingers diminishing in length with respect
to one another towards the middle of said shaft, substantially as described.
5. A hat fastener, comprising a pin or wire, having its ends secured to and
projecting through opposite sides of a hat crown, the ends of said shaft outside
of said crown being removable, and said shaft being arranged to rotate and being
provided with a series of laterally projecting curved fingers between its ends, and
a locking mechanism to prevent the backward rotation of said pin or wire,
substantially as described.
6. A hat fastener, comprising a shaft having flattened or square ends, said ends

page_text: being arranged to project through the opposite sides of a hat crown and rotatably
secured thereto, the removable parts attached to said ends, the end portions of the
shaft being provided with a series of notches or teeth, said renovable ends having
detents to engage the same, a ratchet mechanism to prevent backward rotation of said
shaft, and a series of curved fingers or teeth projeecting laterally therefrom between
its ends, substantially as described.
