PROVISIONAL SPECIFICATION.
An Improved Joint and Pin for Brooches, Badges, and for other
such like Purposes.
CHARLES FREDERICK GRIMMETT & JOSEPH COOк both of Legge Lane Graham
Street Birmingham in the County of Warwick Manufacturers do hereby declare the
nature of this invention to be as follows:-
The object of this invention is an improved machine made joint and pin without
soldering, suitable for Brooches, Badges, and for other such like purposes. And
indeed the Joint and pin are of very general application for a variety of purposes..
We will now describe that part of the invention relating in particular to the joint
which can, both joint & pin be made in gold, silver brass German silver or other
suitable alloys. We first cut out a blank of the desired size & shape then by drawing
through tools or raising tools, we form the blank into a small hollow' cup, one side
being half round & the opposite flat.
The top of the cup or joint when in position is rounded from the flat side to the
half-round, so as to finish with the curve on the pin. A hole is then pierced through
the top of the joint of suitable size & shape to admit of the pin, which when in
position, the joint only requires to be pinched together to secure the pin, the pivot or
bearing on the pin being then enclosed. The pin which is comprised of two parts, is
a piece of wire of any given length pointed or otherwise, it is then bent on one end
into a small curve; a short thicker piece of wire which is then grooved out in the
centre of its length so as to allow the eye on the stem to be closed round it, is then
inserted into the eye or curve so formed on the stem which is then closed tightly
upon it.

COMPLETE SPECIFICATION.
An Improved Joint and Pin for Brooches, Badges, and for other
such like Purposes.
We, CHARLES FREDERICK GRIMMETT, of Legge Lane, Birmingham, in the County of
Warwick, Manufacturer, and ANN Cook, of Heathfield Road, Handsworth, Staffordshire,
Widow and Executrix of the late Joseph Cook, of Legge Lane, aforesaid, Manufacturer,
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:-
The object of this invention is an improved machine made joint and pin without
soldering suitable for brooches, badges, and for other such like purposes. We will
first describe that part of the invention relating more particularly to the joint which
can, as can also the pin, be made from gold, silver, German silver, or other suitable
metal or alloy. We first cut out a blank of the desired size and shape and then by
drawing through tools or by raising tools we form the blank into a small hollow cup
one side being half round and the opposite side flat. The top of this cup or joint
when in position is rounded from the flat side to the half round so as to finish with
the curve on the pin. A hole is then pierced through the top of the joint of a suitable.
size and shape to admit the pin so that when the latter is in position the joint only
requires to be pinched together to secure the pin thereto the pivot or bearing on the
pin being then enclosed. The pin which is comprised of two parts is a piece of wire
of any given length pointed or otherwise and bent at one end into a small curve, a

allow the eye on the stem to be closed round it, is then inserted into the eye or curve
so formed on the stem which is then closed tightly upon it.
We will now refer to the accompanying drawing and describe how the said
invention is to be performed.
Fig. 1 represents a blank for forming the said joint part and Fig. 2 shews the said
blank partly raised into the said joint; Fig. 3 is a front elevation of the said joint
part when ready for the insertion of the pin; Fig. 4 is a side elevation and Fig. 5 a
sectional side elevation of the same and Fig. 6 is a plan of the same; Fig. 7 represents
in side elevation and Fig. 8 in plan the pin for insertion in the joint represented by
the preceeding figures, and Fig. 9 shews the two parts of the said pin separately;
Fig. 10 represents in sectional side elevation and Fig. 11 in plan a brooch provided
with the joint and pin illustrated by the preceeding figures; Fig. 12 represents in
side clevation, Fig. 13 in sectional plan, and Fig. 14 in sectional front elevation and
in front elevation a modification of the joint and pin illustrated by the preceeding
figures; and Figs. 15 and 16 illustrate different stages in the form of the joint part
of the said modified form; Fig. 18 illustrates in side elevation and in sectional plan a
further modification of this invention.
The same letters of reference indicate the same or corresponding parts in, the several
figures.
The
Referring firstly more particularly to Figs. 1 to 11 both inclusive A is the joint and
B is the pin. In making the joint A we cut out a sheet metal blank of about the
shape illustrated by Fig: 1. We then by means of suitable press tools bend up the
curved edges of the blank so as to have about the form represented by Fig. 2.
blank in this form is then bent centrally to the form represented by Figs. 3, 4, 5
and 6 which somewhat represents a small hollow cup one side a' being halfround and
the opposite side a² flat. The top a³ is open and the front a meets at the base a² and
then gapes open above so as to allow for closing to embrace the pin as hereinafter
described. In making the pin B the jointed end ¹ is first curved round into the loop
shape shewn by Fig. 9 a short thicker piece of wire c which forms the pivot of the
pin and which is reduced in diameter centrally at c¹ is then inserted into the eye or
curve b¹ which is then closed tightly upon it so that the cross pin c will be firmly
secured to and form part of the pin as represented by Figs. 7 and 8. The joint A can
thus be soldered or otherwise fixed to the brooch before the pin B is connected to the
joint thus preventing any possibility of the pin being softened during the process of
soldering. The joint end of the pin is then inserted in the open top of the joint A
and the sides of the latter are pinched together so as to enclose the pivot or bearing c
and allow of the pin turning freely thereon.
We sometimes as illustrated by Figs. 12, 13, 14, 15, 16 and 17 provide two hollow
projections a' in the joint A one at each side thereof for the ends of the joint pin c to
work in so as the better to prevent any side movement of the pin B this can readily
be done by raising the said projections in the blank at the same time that the edges
are turned up as illustrated by Fig. 15 so that when the blank is raised into the cup
shape as shewn by Figs. 16 and 17 the opening at the top a³ will be sufficiently wide
to admit of the joint pin e passing into it. Instead of employing a joint pin c which
is fixed to the pin B as above described it will be evident that the pin B can be secured
to the joint A by an ordinary wire joint pin d passing through the joint A and the
eye bas illustrated by Fig. 18.
The accompanying drawing illustrates what we have found the best way for
carrying our invention into practice but it is to be understood that the said invention
is not limited to the precise details hereinbefore described and illustrated.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
"
1. A joint for the pins of brooches, badges, and for other like articles, constructed
substantially as herein before described with wafaransaits Wi

after the same has been inserted in the open top thereof, substantially as set
forth.
2. A joint for the pins of brooches, badges, and for other like articles constructed
substantially as hereinbefore described and illustrated by Figs. 12, 13, 14, 15, 16
and 17 of the accompanying drawing, provided with lateral depressions in which the
ends of the joint pin fit after the brooch or other like pin has been inserted in the
open end of the joint and the sides of the joint closed together, substantially as
set forth.
3. The improved pin B for brooches, badges, and for other like articles provided
with a loop or eye at one end closed round the grooved joint pin c, substantially as
hereinbefore described and illustrated by Figs. 7, 8 and 9 of the accompanying
drawing.
4. The combination with the joint A, constructed substantially in the several ways
hereinbefore described and illustrated, of the pin B having a loop or eye at one end,
the said end being enclosed by the joint and hinged thereto in either of the several
ways substantially as set forth and illustrated by the accompanying drawing.
