Year: 1860

page_text: LETTERS PATENT to Thomas Brookes, of Birmingham, in the County of
Warwick, Manufacturer, and Thomas Adams, of Birmingham, aforesaid,
Manufacturer, for the Invention of "AN IMPROVEMENT OR IMPROVEMENTS
IN THE MANUFACTURE OF THE. JOINTS OF BROOCHES AND OTHER SIMILAR DRESS
PROVISIONAL SPECIFICATION left by the said Thomas Brookes and
Thomas Adams at the Office of the Commissioners of Patents, with
their Petition, on the 27th September 1860.
We, THOMAS BROOKES, of Birmingham, in the County of Warwick, Manu-
facturer, and THOMAS ADAMS, of Birmingham, aforesaid, Manufacturer, do
hereby declare the nature of the said Invention for "AN IMPROVEMENT OR
IMPROVEMENTS IN THE MANUFACTURE OF THE JOINTS OF BROOCHES AND OTHER SIMILAR
DRESS FASTENINGS," to be as follows:-
Our Invention consists of the improvement or improvements herein-after
explained in the method of making the joints of brooches, which said improve-
ment or improvements are also applicable to such other dress fastenings as
fasten by means of a jointed pin.
We will describe our Invention with reference to a brooch. That part of
the joint which is connected to the back of the brooch we make, when it can
be conveniently so made, of two tongues cut from the sheet metal from which

page_text: the back of the brooch is made, and in one piece with the said back. Where,
from the shape of the brooch or otherwise, it cannot be conveniently made
thus, we make it of a separate piece of metal and solder it to the back of the
brooch. The said tongues are afterwards bent into a tubular form. That
part of the joint which is connected to the pin we make from sheet metal in
the following manner:-We cut a blank of a rectangular figure and about
three times as long as wide, the said blank being somewhat broader in one
half of its length than in the other half. The narrow end of the blank is
rolled up into a tubular form and constitutes the middle of the joint. The
other part of the blank is doubled into a trough-like shape, and the pin being
placed therein, the said part is closed upon the pin, which is held firmly therein.
The top of the pin is bent at right angles before the blank is closed upon it,
the bent portion constituting a stop which limits the motion of the joint. The
joint is finished by passing a pin or axis through the two parts in the ordinary
manner.
SPECIFICATION in. pursuance of the conditions of the Letters Patent filed
by the said Thomas Brookes and Thomas Adams in the Great Seal
Patent Office on the 21st March 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
BROOKES, of Birmingham, in the County of Warwick, Manufacturer, and
THOMAS ADAMS, of Birmingham, aforesaid, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of September, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Thomas Brookes and Thomas Adams, Her special licence that we, the
said Thomas Brookes and Thomas Adams, our executors, administrators, and
assigns, or such others as we, the said Thomas Brookes and Thomas Adams,
our executors, administrators, and assigns, should at any time agree with, and
no, others, from time to time and at all times thereafter during the term
therein expressed; should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "AN IMPROVEMENT OR IMPROVEMENTS IN THE
MANUFACTURE OF THE JOINTS OF BROOCHES AND OTHER. SIMILAR DRESS FASTENINGS,"
upon the condition (amongst others) that we, the said Thomas Brookes and
Thomas Adams, our exccutors or administrators, by an instrument in writing

page_text: under our or their hands and seals, or under the hand and seal of one of us
or them, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar inonths
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Thomas Brookes and Thomas Adams,
do hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
Our Invention consists of the improvement or improvements herein-after
particularly described and illustrated in the accompanying Drawing, of making
the joints of brooches, which said improvement or improvements are also
applicable to such other dress fastenings as fasten by means of a jointed pin.
We will describe and illustrate our Invention with reference to the joint of
a brooch, from which description and illustration the application of our Inven-
tion to such dress fastenings as fasten by means of a jointed pin will be readily.
understood. That part of the joint which is connected to the back of the
brooch we make, when it can be conveniently so made, of two tongues cut
from the sheet metal of which the back of the brooch is made, or from the
metal of which the rim or frame of the brooch is made, and in one piece with.
the said back, or rim, or frame. Where, from the shape of the brooch or
otherwise, it cannot be conveniently made in one piece with the back, or rim,
or frame of the brooch, we make it of a separate piece of metal and solder it
to the back, or rim, or frame of the brooch. The other part of the joint is
made from sheet metal in the manner herein-after explained.
Figure 1 of the Drawing represents in plan and edge view a back of a
brooch so shaped that one part of the joint can be made therefrom.
The said back a, Figure 1, is cut from sheet brass, copper, or other metal.
or alloy, by means of cutting tools worked in a press, and at one end of the
said back tongues b, c, are formed; the said tongues b, c, being made in one.
piece with the said back a. At the opposite end of the back ȧ, a projecting.
piece d is left, from which the catch of the brooch is made. The said
tongues b, c, are afterwards rolled up or bent into a tubular form, and the
projecting piece d shaped and bent at right angles to the back a, as represented
in plan in Figure 2, side elevation in Figure 3, and end elevation in Figure 4
of the Drawing; the tubular parts of the joint being marked b, c, and the
finished catch d, in the said Figures 2, 3, and 4. Or we make the parts b³, c³,
of the joint from the same piece of metal as that from which the rim or franie
is made, that is, we make the said rim or frame with two tongues, which

page_text: we bend into a tubular form. The other part of the joint, namely, that which
is connected to the pin of the brooch we make from sheet metal, and fix the
pin thereto in the following manner:-We cut a blank from sheet metal of
a nearly rectangular figure, and about three times as long as wide, the said
blank being somewhat broader in one half than in the other half. A blank of
this kind is represented in plan and edge view in Figure 5. The narrow end e
of the said blank, Figure 5, is rolled up into a tubular form, as represented in
plan and edge view in Figure 6, and constitutes the middle of the joint. The
wide part of the blank, Figure 6, is next doubled into a trough-like shape,
as represented in plan and edge view in Figure 7, and marked g. We take
the pin of the brooch, Figure 8, and after bending the top at right angles, as
shewn in Figure 9, we place it in the said trough g, Figure 7, as represented
in Figure 10, and close the edges of the said trough g upon the pin, which is
held firmly therein, as represented in Figure 11, when this portion of the joint
is complete. The bent portion of the pin, Figures 9, 10, and 11, constitutes
a stop which limits the motion of the joint, as well as springs the pin of the
brooch into its catch, as is well understood. The joint is finished by passing
pin or axis through the two parts of the said joint in the ordinary manner.
Figure 12 represents in plan, and Figure 13 in side elevation, a finished joint
made according to our Invention in the manner already described.
a
We make that part of the joint which is attached to the back, or rim, or
frame of the brooch when it cannot be made conveniently in one piece with
the said back, or rim, or frame, in the following manner:-We cut from sheet
metal a blank of the form represented in plan and edge view in Figure 14,
and turn or coil up the ends of the tongues i, k, into a tubular form, as repre-
sented in plan and edge view in Figure 15, the said tubular parts being
marked and m. We afterwards bend the flat bar n, connecting the two
tubular parts l, m, together, in the manner represented in plan and edge view
in Figure 16, so as to form a raised bar o, the said raised bar o forming the
stop against which the pin bears to spring it into its catch; Figure 17 represents
in edge view that portion of the joint made as described and represented in
Figures 14, 15, and 16, soldered to the back of a brooch. The portion of the
joint made in the manner last described, and that attached to the pin of the
brooch, are connected together by passing a pin or axis through the tubular
parts, as before explained. When we make that portion of the joint which is
soldered to the back of the brooch in the manner represented in Figures 14, 15,
and 16, it is unnecessary to bend the end of the pin before fixing it in the
other portion of the joint, the springing of the said pin being effected in this
case by the raised bar o, Figures 16 and 17. By making the part of the joint

page_text: connected with the back or rim in one piece therewith the necessity for
soldering is avoided, and by connecting the other part of the joint with the pin
in the manner described, the hardness or temper of the pin is not affected, as
commonly happens when the pin is attached by soldering. The partly made
brooch, Figures 12 and 13, is ornamented and finished by attaching the
requisite parts and ornaments to it in the ordinary manner.
Having now described the nature of our Invention and the manner of
carrying the same into effect, we wish it to be understood that we do not limit
ourselves to the precise details herein described and represented, as the same
may be varied without departing from the nature of our Invention; but we
claim as our Invention, the improvement or improvements in the manufacture
of the joints of brooches and other similar dress fastenings, herein-before
described and illustrated in the accompanying Drawing, that is to say, making
one portion of the said joints from tongues made in one piece with the back,
or rim, or frame of the brooch or dress fastening, and coiled or bent into a
tubular form; or from separate tongue-shaped blanks coiled or bent into a
tubular form, and afterwards soldered to the back, or rim, or frame of the
brooch or dress fastening, the other portion of the joint being made from
blanks of sheet metal bent and fashioned, and the pin of the brooch or dress
fastening fixed thereto in the manner herein-before described and illustrated.
In witness whereof, we, the said Thomas Brookes and Thomas Adams,
have hereunto set our hands and seals, this Twentieth day of March, in
the year
of our Lord One thousand eight hundred and sixty-one.
