Improvements in Securing Brooch Pins to Brooches.
I, MATTHEW HENRY TILLEY, of 46, South Street, Dorchester, in the County of
Dorset, Watch and Clock Maker and Jeweller, do hereby declare the nature of this
invention to be as follows:-
This invention consists of the improvements herein described in securing brooch.
pins to brooches the object being to enable, any inexperienced person to remove a
broken brooch pin and replace it by a new one.
In carrying out my invention I make the brooch pin of the usual form that is to
say it has a transverse eye at its jointed end for the joint pin to pass through. I make
the joint pin in the shape of the letter U, that is say, it consists of two parallel limbs
connected together one of the said limbs forming the joint pin proper and the other
limb forming what I call the bolt pin which, as hereinafter described, secures the
joint pin proper in position. The joint to which the brooch pin is hinged and which
is soldered to the brooch, consists of a pair of ears as usual one at each side of the
brooch pin for the joint pin proper to pass through, and at the side of these ears and
parallel therewith I provide a tube into which the bolt pin fits. The free end of
the bolt pin is enlarged so that when in position it will snap through the end of the
tube and hold the joint pin in position. The junction of the joint pin and bolt pin
proper is by preference formed to stand up so as to enable the joint pin to be
withdrawn by the thumb_nail far enough to remove a broken pin from the brooch
or to insert a new one. In order to prevent the joint pin being withdrawn too far
I make an indentation in the tube with which the enlarged end of the bolt pin comes
in contact when it has been withdrawn far enough to allow of a new brooch pin being
placed in position.
By withdrawing the combined joint pin and bolt pin until their further motion is
arrested by the enlarged end of the bolt pin coming into contact with the indentation
as above described, the brooch pin can be removed from the joint or replaced, and
when replaced it is only necessary to push the combined joint pin and bolt pin.
back to their former position and the brooch pin is secured to the brooch as
required.

Improvements in Securing Brooch Pins to Brooches.
I, MATTHEW HENRY TILLEY, of 46, South Street, Dorchester, in the County of
Dorset, Watch and Clock Maker and Jeweller, 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 :-
This invention consists of the improvements herein described in securing brooch
pins to brooches the object being to enable any inexperienced person to remove a
broken brooch pin and replace it by a new one.
In carrying out my invention I make the brooch pin of the usual form that is to
say it has a transverse eye at its jointed end for the joint pin to pass through. I
make the joint pin in the shape of the letter U, that is to say, it consists of two
parallel limbs connected together one of the said limbs forming the joint pin proper
and the other limb forming what I call the bolt pin which, as hereinafter described,
secures the joint pin proper in position. The joint to which the brooch pin is hinged
Din 877

page_text: and which is soldered to the brooch, consists of a pair of ears as usual one at each
side of the brooch pin for the joint pin proper to pass through, and at the side of
these ears and parallel therewith 1 provide a tube into which the bolt pin fits. The
free end of the bolt pin is enlarged so that when in position it will snap through the
end of the tube and hold the joint pin in position. The junction of the joint pin and
bolt pin proper is by preference formed to stand up so as to enable the joint pin to be
withdrawn by the thumb nail far enough to remove a broken pin from the brooch or
to insert a new one. In order to prevent the joint pin being withdrawn too far I
make an indentation in the tube with which the enlarged end of the bolt pin comes
in contact when it has been withdrawn far enough to allow of a new brooch pin being
placed in position.
By withdrawing the combined joint pin and bolt pin until their further motion is
arrested by the enlarged end of the bolt pin coming into contact with the indentation
as above described, the brooch pin can be removed from the joint or replaced, and
when replaced it is only necessary to push the combined joint pin and bolt pin back
to their former position and the brooch pin is secured to the brooch as required.
On the accompanying drawing Fig. 1 represents in plan a brooch and brooch
tongue or pin provided with a joint and joint pin constructed according to this
invention; Fig. 2 is an end view and Fig. 3 is a side elevation of the same, and
Fig. 4 is a cross section of the same with the joint pin removed. In Figs. 3 and 4
only part of the brooch is shewn. Fig. 5 is a sectional plan of the joint and joint
pin of the same with the brooch tongue or pin removed. Fig. 6 represents the
said joint, joint pin, and the end of the brooch tongue detached from each other;
Fig. 7 represents in plan and sectional elevation the joint part of the same separately;
Fig. 8 is a view of the blank for forming the joint and Figs. 9 and 10 illustrate
how the said blank has to be bent to form the joint.
The same letters of reference indicate the same parts in all the figures of the
drawing.
A is the brooch and B is the brooch tongue or pin of the usual form provided with
the transverse eye b at its jointed end as usual. C is the joint pin which, as seen in
Fig. 6, is made from a piece of wire bent into the shape of the letter U one limb c¹
being pointed and forming the joint pin proper and the other limb c² forming what
I call the bolt pin. is the loop part of the joint pin which is bent upwardly, as
seen more clearly in Figs. 2 and 3, so as to facilitate the withdrawal of the joint pin
from the joint. D is the joint provided with the usual base d' for soldering to the
back of the brooch and also provided with the usual ears d² d² at the sides of the
brooch-pin B into which the joint pin c¹ takes so as to connect the brooch-tongue B.
with the joint. d³ is the tube parallel' with the ears d² and fixed thereto for the bolt
pin to take into.
The outer ends of the limbs c¹ c² of the joint pin Care made to spring a short
distance apart when the joint pin is removed from the joint, as in Fig. 6, and the
outer end of the limb is enlarged or has a lateral projection c¹ so that when the
combined joint pin and bolt pin are inserted in the joint and pushed home as shewn
in Fig. 1, by the limb springing apart the end c will engage with the other side of
the joint and so hold the joint pin in position. To remove the joint pin C the
end of the limb has to be pressed towards the limb c¹ until the end will enter
the hole in the tube d³; the joint pin C is then withdrawn far enough to allow the
brooch-tongue B to be placed in position in the joint or removed therefrom. After the
joint pin C has been pushed home in the joint the tube d is indented at d' thereby
causing a projection inside with which the end c* of the joint pin comes into contact
(see Fig. 5) so as to prevent the joint pin being withdrawn farther than is necessary
for the removal of the brooch-tongue B.
The ears d² and the tube d³ and the usual projecting web or rib d' at the side of the
ears dare by preference formed together from a single blank of the shape
represented in Fig. 8 which, by means of suitable dies worked in a press or
otherwise, is bent into the form represented by Fig. 9; the ends are then closed
round as shewn in Fig. 10 and this part is then soldered on to the base d¹ to

page_text: complete the joint. I have found this method of forming the joint to answer well
in practice but it will be evident that the same might be made in other ways so as to
combine the tube d³ with the ears d' without departing from the nature of my
invention; as for instance the joint might be made as represented by Fig. 11 where
the ears d' and web or rib d' are made together in the usual way and the tube dis
made as a separate piece and soldered thereto.
In conclusion I wish it to be understood that I do not limit myself to the precise
details hereinbefore described and illustrated by the accompanying drawing as the
same may be varied without departing from the nature of this invention, but,
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The herein described improved joint pin for removably securing a brooch
tongue or pin to a brooch joint, that is to say, a joint pin for the purpose described
consisting of two parallel limbs formed or fixed together at one end one of the said
limbs being adapted to enter the ears of the joint and the eye of the brooch pin as
usual and the other limb being formed to engage with the joint and removably
secure the joint pin in position, substantially as described and illustrated.
2. The improved joint pin C for renovably securing a brooch tongue or pin to a
brooch joint, consisting of the limbs c c and the loop c² constructed substantially as
and for the purposes set forth.
3. In a joint for securing a brooch tongue or pin to a brooch and in combination
with the usual ears d d of the joint through which the joint pin passes, the tubular
part d³ made with or without the indentation d', substantially as and for the purposes
described.
4. The improved joint D, for securing a brooch tongue or pin to a brooch,
constructed substantially as hereinbefore described and illustrated by the accom-
panying drawing.
5. The combination with a brooch tongue or pin of a joint and joint pin con-
structed substantially as hereinbefore described and illustrated by the accompanying
drawing so as to allow of the brooch tongue or pin being readily removed from the
joint and readily replaced as herein before set forth.
