Year: 1868

page_text: LETTERS PATENT to George Edmund Donisthorpe, of Leeds, in the
County of York, Engineer, for the Invention of "IMPROVEMENTS IN
THE CONSTRUCTION OF AND MODE OF FIXING JOINTS, CATCHES, OR OTHER
FASTENINGS FOR BROOCHES AND OTHER ORNAMENTS AND ORNAMENTAL
MOUNTINGS AND FITTINGS FOR FURNITURE AND ARTICLES OF VERTU."
Sealed the 30th June 1868, and dated the 7th January 1868.
PROVISIONAL SPECIFICATION left by the said George Edmund
Donisthorpe at the Office of the Commissioners of Patents, with
his Petition, on the 7th January 1868.
I, GEORGE EDMUND DONISTHORPE, of Leeds, in the County of York,
Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF AND MODE OF FIXING JOINTS, CATCHES,
OR OTHER FASTENINGS FOR BROOCHES AND OTHER ORNAMENTS AND ORNAMENTAL
MOUNTINGS AND FITTINGS FOR FURNITURE AND ARTICLES OF VERTU," to be as
follows:-
My Invention consists in placing the pins at an angle, and forming the
joint in two parts, instead of making the pins straight and the joint in
one piece as heretofore. The pin commonly called the joint pin secures

page_text: the whole in a fixed position. In order to fix the joints, catches, or
other fastenings I employ an upright slide with two cross slides
travelling at unequal speeds regulated by means of screws, and in the
upper cross slide I place two adjustable face plates with holes suitably
placed to admit a drill at any suitable angle to drill the holes for the
pins.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said George Edmund Donisthorpe in the Great Seal
Patent Office on the 4th July 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
EDMUND DONISTHORPE, of Leeds, in the County of York, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Seventh day of January, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-first
year of Her reign, did for Herself, Her heirs and successors, give and
grant unto me, the said George Edmund Donisthorpe, Her special
licence, that I, the said George Edmund Donisthorpe, my executors,
administrators, and assigns, or such others, as I, the said George,
Edmund Donisthorpe, my 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 "IMPROVEMENTS IN THE CONSTRUCTION OF AND MODE OF
FIXING JOINTS, CATCHES, OR OTHER FASTENINGS FOR BROOCHES AND
ORNAMENTS AND ORNAMENTAL MOUNTINGS AND FITTINGS FOR FURNITURE AND
ARTICLES OF VERTU," upon the condition (amongst others) that I, the said
George Edmund Donisthorpe, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and.
seals, 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
months next and immediately after the date of the said Letters.
Patent.

page_text: NOW KNOW YE, that I, the said George Edmund Donisthorpe, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Drawing
hereunto annexed, and to the letters and figures marked thereon (that
is to say):-
My Invention of "Improvements in the Construction of and Mode
of Fixing Joints, Catches, or other Fastenings for Brooches and other
Ornaments and Ornamental Mountings and Fittings for Furniture and
Articles of Vertu," relates, first, to a novel mode of constructing the
joint, and of adapting the brooch pin thereto; and, secondly, to the
mode of fixing or securing the fastenings and catches to the brooch or
other article to which it is to be adapted. The pins whereby the long
brooch pin and joint is secured to the brooch or other article are placed
at an angle or in an inclined position, and the joint plate or foundation
is formed in two parts, instead of the securing pins being made vertical
and the joint plate or foundation formed of one piece as heretofore.
The hinge pin which is commonly called the joint pin passes through
sockets attached to the two parts of the joint plate, and also through the
boss of the brooch pin, and thus secures the three parts together. The
catch to secure or hold the tail end of the brooch pin is formed in the
same manner of three parts which are secured together by a cross
pin.
In the accompanying Drawing I have shewn various views of one
of my improved fastenings suitable for a jet brooch or other ornamental
article.
Fig. 1 is an end view of the fastening complete and fixed in place;
Fig. 2 is a side view, and Fig. 3, a plan or back view of the fastening;
Fig. 4 is another plan or back view of the fastening with the long
brooch pin and its boss shewn at Figures 2 and 3 removed.
It will be seen that the fastening consists of three parts, namely, the
two half plates a, a, and the long central pin 6, with its boss. Each of
the half plates a, a, is provided on the back with a socket piece a', a', to
receive the cross pin which secures all the parts together. On the face
of the plates a, a, are fixed the angular pins c, c, which in order to
secure the fastening to the brooch or other article é are inserted
into diagonal holes made therein as shewn at Fig. 1.

page_text: Figures 5 represent side and end views of one of the half plates
shewing the diagonal holding pins c, c. The head or boss of the long
brooch pin 6 is also pierced so as to form a socket to receive the cross pin,
and the boss of the pin b is also provided with a leg 6' which extends at
right angles from the body of the pin and rests upon the back of the
plates a, as seen at Fig. 2. When the diagonal pins c, c, of each of the
half plates a, a, are inserted into the holes in the brooch or other
article e, the boss or socket of the brooch pin 6 is placed between the
two sockets of the half plates a, a, and all the parts are secured together
by means of a cross pin or hinge pin as already described. The catch or
curved hook to hold the tail end of the brooch pin 6 is also formed of
three parts which are secured together in the same manner by a cross
pin.
Fig. 6 is an elevation, and Fig. 7 a plan view of a catch made upon
the improved system. a, a, are the two half plates provided on their
faces with sockets a', a', and on their under sides with angular pins c, c,
which are to be inserted into diagonal holes in the brooch or other
article as in Fig. 1. The block or boss d which carries the catch or
curved hook d¹ is made with a flat bottom and sides in order to fit and
lie flat against the half plates and their sockets, and a hole is made
through the sockets a¹ and the boss d of the catch, and through this
hole is passed a cross pin as indicated by dots so as to hold all the parts
together.
It will be understood from the foregoing description that in order to
adapt and secure these fastenings and catches to a brooch or other article
diagonal holes are made in the article as shewn at Fig. 1, for the
reception of the inclined or diagonal pins c, and when the half plates
a, a, are in place the boss b' of the brooch pin in the one case, and the
block or boss d of the catch in the other, are placed between the
sockets a', a', and the cross pin being passed through them, all the parts
will be held securely together.
Having now described my Invention of "Improvements in the
Construction of and Mode of Fixing Joints, Catches, or other Fastenings
for Brooches and other Ornaments and Ornamental Mountings and
Fittings for Furniture and Articles of Vertu," and having explained the
manner of carrying the same into effect, I claim as the Invention secured
to me by Letters Patent as aforesaid, the mode herein set forth of
constructing the joints of fastenings and catches, and also the mode

page_text: shewn and described of fixing, or adapting, and securing them to
brooches and other articles whether for ornament or use.
In witness whereof, I, the said George Edmund Donisthorpe, have
hereunto set my hand and seal, the First day of July, in the
year of our Lord One thousand eight hundred and sixty-eight.
G. E. DONISTHORPE. (L.S.)
