Improvements in Tongues or Pins and Joints for Brooches and
the like.
I, FRANCIS TAYLOR, of Whitchurch in the County of Salop, Jeweller, do hereby
declare the nature of this invention to be as follows:-
This invention has for its object a tongue or pin that can at once be fitted to a
brooch by the wearer, without having to take it to a jeweller.
In place of the usual hinged joints and pins, I use a pin with a hooked or twisted
end and joint so shaped that the pin can be sprung into place, its own springy nature,
and a flat place upon it preventing it being brought back without considerable force,
into the position where it was slipped into place, and from which it could be withdrawn.
There are numerous ways of doing this, by one plan I form the joint of a simple,
rectangular, projecting, piece, with a hole in the centre line through it near the base,
longitudinally to the lie of the pin when in use, and a groove for the pin to lie in
nearly or quite parallel with the hole and above it. The pin is hooked at the end and
has two wings flat on the inside on the hooked part-the pin is slipped on by pushing
its point into the hole from the catch side, then forcibly turning the pin round till
when it is at right angles to the brooch the flat wings spring flat against the flat sides
of the joint and prevent it being brought back further, while opening with gentle
pressure to enable the pin to be caught in the catch. Another cheaper but inferior
plan is to have the pin straight and the wings more rounded, but the joint elastic, and
bent over the wings in a hooked form. In this case flats on the wings also prevent
the pin being forced back too far, and give the resistance requisite for the pin to
require some pressure to enable it to enter the catch. A ball prism or other projecting
device can take the place of the wings so as to form a thickened part on the pin.

Improvements in Tongues or Pins and Joints for Brooches and
the like.
I, FRANCIS TAYLOR, of Whitchurch, in the County of Salop, 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 has for its object a tongue or pin that can at once be fitted to a brooch
by the wearer, without having to take it to a jeweller.
In place of the usual hinged joints and pins, I use a pin with a hooked or twisted
end and joint, so shaped that the pin can be sprung into place, its own springy nature,
and a flat place upon it preventing it being brought back without considerable force,
into the position where it was slipped into place, and from which it could be
withdrawn.
There are numerous ways of doing this, one plan is shown in the accompanying
drawings, in which,
Figure 1, is a plan of the improved brooch pin before the end is bent into a loop
or eye.
Figure 2, an end view of the same.
Figure 3, a plan of the joint to which the pin is attached.
Figure 4, an elevation of Figure 3.
Figure 5, an elevation of a brooch with a joint secured thereto, showing the mode
of inserting the pin.
will
Figure 6, an elevation of a brooch with a pin sprung into place and ready for use.
In these A is a joint or bracket preferably formed of simple rectangular projecting
pieces, secured in any convenient manner to the brooch G. It is provided with a
hole B or opening near the base longitudinally to the lie of the pin when in use, and
a groove C for the pin to lie in nearly or quite parallel with the hole B. D is the
brooch pin which has wings E at right angles thereto. The pin is slipped on by
pushing its point into the hole B, see Figure 5, and drawing it through as far as it
༢༠, then forcibly turning the pin round till one side of the wings Ẽ abuts against
the pin, so as to form a loop or eye, see Figure 6. When a gentle pressure is applied
the pin is caught by the catch F. In use, when the pin is released from the catch,
the wings E abut against the joint A when the pin is at or about right angles with
the brooch G. The pin is thus prevented from being turned back into the position
where it was slipped into place, and from which it could be withdrawn, unless
considerable force is applied. The length of the wings E is preferably about the
same as the distance between the size of the joint or bracket A, so as to prevent the
pin shaking about. Another cheaper but inferior plan is to have the pin straight, and
the wings more rounded, but the joint elastic, and bent over the wings in a hooked
form. In this case flats on the wings also prevent the pin being placed back too far,
and give the resistance requisite for the pin to require some pressure to enable it to

wings so as to form a thickened part on the pin.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, I declare that what I claim is :—
1. The manufacture and use of tongues or pins and joints for brooches and the
like, in such manner that the pin can be sprung into place, its own springy nature and
the peculiar contour of the pin or joint being such that when once sprung into place
the pin,shall be free to oscillate the desired extent, but shall be incapable of being
withdrawn from the joint without considerable force being exerted, and that preferably
only when the pin is in a position beyond its ordinary range of oscillation.
2. The pins and joints constructed and arranged substantially as and for the purposes
described.
