1, JOHN LONG, of Bradninch, Devonshire, Jeweller, do hereby declare the nature of
this invention to be as follows :-
This Invention has reference to certain improvements in those fastenings of brooches
and other articles of jewellery commonly known as Long's Patent Safety Locks for
which Letters Patent were originally granted to me bearing date January 17th,
A.D. 1857, Number 150.
Heretofore the outer casing of such a fastening or lock has been constructed as
described in the Specification and illustrated by the drawing of my herein before
mentioned Letters Patent, which outer casing consisted of a box of thin metal (within
which were arranged the hooked catch piece and helical spring) having a plate
attached to one side by small screws. An outer casing so constructed is expensive to
manufacture and moreover as the said screws require to be rivetted over at their ends
when in position so as to prevent their becoming loose it is a very difficult matter to
open the said casing and to remove the coiled spring therefrom. Thus many fastenings
have been rendered useless through the said spring being heated and rendered soft
during the operation of soldering the casing to the brooch or other article of jewellery
with which it is required to be used.
My present Invention consists in constructing the said outer casing of a single piece
of sheet metal, as hereinafter described, whereby the cost of manufacture is consider-
ably reduced and the necessity of using screws is dispensed with, and the said coiled
spring can readily be removed from and replaced in the casing without disturbing any
other part of the lock or fastening.
I will describe my Invention as applied to a brooch.
In carrying out my Invention I take an oblong rectangular sheet metal blank
having centrally an oblong hole extending to within a short distance of each end. The
said sheet metal blank is of suitable size to form the outer casing of the lock or fastening.
I bend the said blank centrally in the direction of its shorter axis into a n-shape (when
viewed from one end) thus forming two sides and the top of the casing, and the oblong

page_text: hole will then form the recess in which the brooch pin rests when held by the hooked
catch. Between the two sides thus formed I place the hooked catch which is pivotted
on a pin passing thereto and rivetted over at each end. The ends of the said blank or
the extremities of the form the base of the fastening where it is soldered to the
back of the brooch.
•
The coiled spring which acts upon the heel of the hooked catch in the ordinary
manner re-acts against the top of the n-shaped casing. The top of the and the
heel of the hooked catch are indented or otherwise formed so that the ends of the
spring will catch thereon and be there maintained by the elasticity of the spring. By
merely compressing the spring its ends can be sprung out of or into the said
indentations so that it can readily be removed or replaced through the end opening
of the .
When used as a fastener for bracelets, necklets or other chains the sheet metal
blank is preferably made with rounded ends so as to form a rounded base which may
be pierced for a ring to pass through to attach it to one end of the bracelet, necklet or
other chain, a ring at the other end being employed for the hooked catch to take in.
The oblong form of the blank for forming the outer casing may be modified without
departing from the nature of my Invention for instance the blank may be approxi-
mately a rectangular oblong and have a deep indentation at each end so that when
bent centrally into a U-shape such central part will form the base of the outer casing.
The extremities of the U are then bent over and soldered or otherwise fixed together
to form the top of the outer casign.

page_text: I, JOHN LONG, of Bradninch, Devonshire, 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 reference to certain improvements in those fastenings of brooches
and other articles of jewellery commonly know as Long's Patent Safety Locks for
which Letters Patent were originally granted to me bearing date January 17th
A.D. 1857, Number 150.
Heretofore so far as I can ascertain the outer casing of such a fastening or lock has
been constructed as described in the Specification and illustrated by the drawing of
my hereinbefore mentioned Letters Patent, which outer casing consisted of a box of thin
metal (within which were arranged the hooked catch piece and helical spring) having
a plate attached to one side by small screws. An outer casing so constructed is
expensive to manufacture, and moreover, as the said screws require to be rivetted over
at their ends when in position so as to prevent their becoming loose, it is a very
difficult matter to open the said casing and to remove the coiled spring therefrom.
Thus nany fastenings have been rendered useless through the said spring being
heated and rendered soft during the operation of soldering the casing to the brooch or
other article of jewellery with which it is required to be used.
My present Invention consists in constructing the said outer casing of a single piece
of sheet metal, as hereinafter described, whereby the cost of manufacture is consider-
ably reduced and the necessity of using screws is dispensed with, and the said coiled
spring can readily be removed from and replaced in the casing without disturbing any
other part of the lock or fastening.
I will describe my invention by referring to the accompanying drawing Fig. 1 of
which is a side sectional elevation and Fig. 2 a plan of my improved fastening closed,
Fig. 3 is an end view of the same looking towards the coiled spring and Fig. 4 is also an
end view looking towards the hooked catch; Fig. 5 represents a similar view to Fig. 1
with the catch open; Fig. 6 represents in side and end elevations and in plan the
sheet metal outer casing of the same separately and Fig. 7 shows an elevation and
plan of the hooked catch separately; Fig. 8 represents a sheet metal blank for forming
the outer casing represented by Fig. 6 and Fig. 9 represents a back view of an
inverted brooch with the improved fastening shewn by the preceeding Figures applied.
Figs. 10 and 11 shew the improved fastening applied for securing the ends of a
bracelet, necklet or other chain; Fig. 12 shews a modified form of outer casing and
Fig. 13 the sheet metal blank for forming the same, Fig. 14 representing the modified
outer casing partly formed.
Similar letters refer to similar parts throughout the several Figures.
Referring firstly more particularly to Figs. 1 to 9; both inclusive, a is the outer
casing of the fastening, 6 is the hooked catch working loosely on a pin c and d is the
spring which acts upon the heel of the hooked catch to maintain it closed.

page_text: In carrying out my invention as applied to the fastening for a brooch I take an
oblong rectangular sheet metal blank (see Fig. 8), having centrally an oblong hole a
extending to within a short distance of each end. The said sheet metal blank is of
suitable size to form the outer casing a of the lock or fastening. I bend the said blank
centrally in the direction of its shorter axis into a n-shape (when viewed from one
end) see Fig. 6, thus forming two sides a², a³ and the top a¹ of the casing, and the
oblong hole a¹ will then form the recess in which the brooch pin rests when held by
the hooked catch (see Fig. 9). Between the two sides a², a³ thus formed I place the
hooked catch b which is pivotted on a pine passing therethrough and rivetted over at
each end. The ends of the said blank or the extremities as of the form the base of
the fastening where it is soldered to the back of the brooch (see Fig. 9).
The coiled spring d which acts upon the heel b¹ of the hooked catch in the ordinary
manner re-acts against the top at of the n-shaped casing. The top at of the n-shaped
casing and the heel of the hooked catch are indented (see Figs. 1 and 5) or otherwise
formed so that the ends of the spring d will catch thereon and be there maintained by
the elasticity of the spring. By merely compressing the spring d its ends can be
sprung out of or into the said indentations so that it can readily be removed or
replaced through the end opening of the n-shaped casing.
When used as a fastener for bracelets, necklets or other chains the sheet metal blank
is preferably made with rounded ends (see Figs. 10 and 11) so as to form a rounded
base which may be pierced by holes e¹, e² for a ring f to pass through to attach it to
one end of the bracelet, necklet or other chain a ring g at the other end being em-
ployed for the hooked catch b to take in. The fastening is represented as closed round
the ring g in Fig. 10 and unfastened therefrom in Fig. 11.
The oblong form of the blank for forming the outer casing a may be modified with-
out departing from the nature of my Invention for instance the blank may be approxi-
mately a rectangular oblong as shewn by Fig. 13 and have a deep indentation a at each
end so that when bent centrally into a U-shape (see Fig. 14) such central part will
form the base a of the outer casing. The extremities a' of the U are then bent over
and soldered or otherwise fixed together (see Fig. 12) to form the top of the outer
casing.
The fastening above described operates to hold a brooch pin and is operated to
unfasten the same in the well known manner described in the Specification of my
hereinbefore mentioned Letters Patent No. 150 of A.D. 1857.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is :-
1st. The improvements, in the particular kind of fastenings forming the subject of
Letters Patent No. 150 of A.D. 1857 for brooches and other articles of jewellery,
