page_text: I, FREDERICK WILLIAM HILLIAR, of 23, Gloucester Road, Bishopston, Bristol,
Watchmaker, do hereby declare the nature of this invention to be as follows:-
This invention relates to the joints and pins of brooches and the like.
According to one arrangement comprised in this invention the joint is constructed
and arranged as follows:
To the heel or joint end of the pin is attached a plate on one face of which is
loosely pivotted a crank carrying a spring tongue. In the spring tongue is a
hole. The plate at joint end of the pin is slotted from the rear end inwards to
a given distance. A cover plate or guard is placed outside the crank.
The said
crank has play between the cover plate and the face of the plate at joint end of
pin. A hinge pin is fixed between two cheeks or side supports situated at a suitable
distance apart.
In applying the brooch pin to the socket in which it is to be hinged, the hinge pin
bears against one arm of the crank and turns the crank upon its pivot. By this
means the spring tongue is raised by its flexibility over a stud fixed in the heel
plate. The stud enters the hole in the tongue, and the spring tongue then
rebounds. The crank thus becomes fixed. In the said movement of the crank one
of its arms is brought up to close the outer end of the slot in the heel plate.
Accordingly, the hinge pin is surrounded, and the heel plate is free to move about
it, but cannot be removed until the spring tongue is freed from engagement with
the stud aforesaid. Instead of having a hole in the spring tongue and a stud on
the heel plate, the stud may be fixed on the tongue and a recess for the stud to
engage with provided in the heel plate.
Stops are fixed to the heel plate to prevent the crank when loose from getting
locked before fixing the pin in position in the socket.
According to another arrangement, a spring by which the crank is secured in
position is fixed to the heel plate or to the cover plate.
Under another modification, the crank is dispensed with and a spring attached to
the heel plate of the pin. The spring engages with pivots outside the said cheeks;
or pivots provided in the spring may engage with holes in the cheeks. Two springs
may be used instead of one only.
Ünder another modification, slotted cheeks or sides are attached to the heel of
the brooch pin the side pieces being fitted with springs which engage by means of
holes with the hinge pin attached to the brooch.

page_text: I, FREDERICK WILLIAM HILLIAR, of 23, Gloucester Road, Bishopston, Bristol,
Watchmaker, 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 relates to the joints whereby the pins of brooches, shawl-pins and
the like are hinged.
According to one arrangement comprised in this invention, the pin of a brooch,
shawl-pin or the like, is hinged or pivotted in the manner following. The hinge
pin about which the pointed pin is to turn is fixed between two cheeks formed or
secured on the body of the brooch or the corresponding part in other articles
having pins like brooch pins.
For convenience in description the invention will be referred to as applied to a
brooch. Its application to other articles of a like or analogous kind is precisely
similar.
To the heel or joint end of the pointed pin is attached a plate which is slotted
from the rear end inwards to a given distance. On one face of the heel plate is
pivotted a crank one limb of which acts as a spring. The other limb is shaped like
a hook. A cover plate may be placed over the crank, and, when this is the case,
the crank has play between the cover plate and the face of the heel plate on which
the crank is pivotted. The cover plate can be dispensed with.
In
In applying the brooch pin to the fixed hinge pin about which it is to turn,
the crank, which has been previously set to clear the slot in the heel plate, is
moved by contact with the fixed hinge pin. The crank turns on its pivot and its
hooked limb comes down behind the fixed hinge pip and closes the slot.
the movement of the crank, its spring arm travels by its flexibility over a swell
formed in the heel plate, and after passing over this swell the spring arm rebounds
and thus locks the crank. The hinge pin is enclosed in the slot and the heel plate
carrying the pointed pin is free to turn on the hinge pin. The heel plate cannot
be removed until the spring arm of the crank is moved back over the swell in the
heel plate.
Instead of locking the crank by means of a swell, locking may be effected, either
by a stud carried by the spring arm and taking into a hole in the heel plate,
or a stud may be formed on the heel plate to take into a hole in the spring arm.
Or, a spring may be fixed to the heel plate and arranged to lock the crank by
rebounding after being depressed by the passage of the crank.
According to another arrangement, the crank is used without a spring, and
works in the heel plate which is divided to allow of such working. In this arrange-
ment, the crank is set to the closed position after the heel plate has been adjusted
on the fixed hinge pin.
Under another arrangement, the crank is dispensed with, and the heel plate is
locked in place on the fixed hinge pin by a spring which is attached to the heel
plate and has a hole in it by which the spring is connected to the hinge pin.
Referring to the accompanying drawings, which are made to an exaggerated
scale, being twice full size, Fig. 1 represents a side view of a brooch adapted for
receiving its pin in accordance with this invention. Fig. 2 is a plan of the back of
the brooch. Secured to or formed with the body a of the brooch is a pair of

page_text: cheeks 6 between which is the hinge pin c. This hinge pin is a permanently fixed
pin and does not require to be removed when attaching or detaching the heel
plate carrying the pointed pin by which the brooch is fastened to wearing apparel.
Fig. 3 is a view of one side of the brooch pin d and Fig. 4 a view of the reverse
side. At the rear end the pin d is fixed to a heel plate e which is designed to fit
loosely between the cheeks 6 of the brooch. The heel plate has a slot el made in
it and extending inwards to a given distance from the rear end. Pivotted on a
stud projecting from one face of the heel plate e, is a crank g, one limb g¹ of
which acts as a flat spring. The other limb 92 is shaped like a hook. Projecting
outward from that face of the heel plate e which carries the crank 9, is a swell or
boss h raised slightly above the general level of the face of the heel plate.
In applying the brooch pin d to the hinge pin c, the crank g is first moved to
the position shown at Figs. 3 and 4, so that the slot e¹ is open at the rear. By
pressure of the crank against the hinge pin c, the crank is caused to turn on its pivot ƒ,
the spring limb g' of the crank springs over the swell h and locks the crank, the
hooked limb g of which closes the slot behind the hinge pin c, as shown at Fig. 5.
The brooch pin is now locked in place and cannot be removed without first releasing
and turning back the crank g.
Arrangements for locking the crank may vary. For example, instead of
locking by means of a swell or boss such as h, locking may be effected either by a
stud carried by the spring arm and taking into a hole in the heel plate, or a stud
may be formed on the heel plate to take into a hole in the spring arm. Or, a
spring may be fixed to the heel plate and arranged to lock the crank by rebounding
after being depressed by the passage of the crank.
At Figs. 6, 7 and 8 is shown a modification according to which a crank is used
without a spring action. In this arrangement the heel plate i is divided, and the
crank is placed in the division. The crank is movable about the pivot k.
At Fig. 6 the crank is shown as tilted to allow the hinge-pin to enter the slot in
the heel plate i. At Fig. 7 the crank is shown as tilted to the position at which it
closes the slot and causes the hinge pin to be enclosed. Movement of the crank
is effected by the application thereto of the finger of the operator, or by any
suitable instrument.
Fig. 8 is a plan of Fig. 7. The pivot pin k of the crank j is in the same plane
longitudinally with the hinge pin and the crank does not move from the position
shown at Fig. 7 unless forcibly turned.
At Figs. 9. 10 and 11 is illustrated a modified method of securing the brooch pin
in place on the fixed hinge pin m. The slotted heel plate n has fixed to it a
spring o which, when the hinge pin is in position in the slot, clips upon one end of
the hinge pin m, as shown more particularly at Fig. 10 which is an underside
view of Fig. 9. At Fig. 11 the spring o is shown partly broken away revealing the
heel plate.
The converse arrangement to this may be adopted, that is to say, an arrangement
in which the heel plate is divided and one lug only fixed to the brooch body
instead of a pair of cheeks.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that what
I claim is:
-
1. Method of hinging the holding pins (that is to sav, the pins which enter the
dress material) of brooches, shawl-pins and the like, namely, by a joint comprising
a pair of checks with a permanently fixed hinge pin, a slotted heel plate attached
to the holding pin and a crank pivotted in or upon the heel plate and adapted to
close the slot either as the heel plate is being inserted in place or thereafter, sub-
stantially as hereinabove described with reference to Figs. 1 to 8 of the accompanying
drawings.
2. The modification hereinabove described with reference to Figs. 9, 10 and 11

page_text: of the accompanying drawings, according to which the holding pin is retained in
position by a spring or springs attached to the said holding pin or to the slotted
heel plate and sprung on to the fixed hinge pin.
