PATENT to Clinton Edgcumbe Brooman, of the Firm of
Robertson, Brooman, and Company, of 166, Fleet Street, in the City
of London, Patent Agents, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF LACE."-A communication from abroad by Désiré
Sival and Leon Sival, both of Roubaix, France.
Sealed the 9th April 1868, and dated the 28th October 1867.
PROVISIONAL SPECIFICATION left by the said Clinton Edgcumbe Brooman
at the Office of the Commissioners of Patents, with his Petition, on
the 28th October 1867.
I, CLINTON EDGCUMBE BROOMAN, of the Firm of Robertson, Brooman, and
Company, of 166, Fleet Street, in the City of London, Patent Agents, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF LACE," to be as follows:-
This Invention relates to "Paris point," and consists in particular
arrangements of the bars of lace machines, constituting a new system of
numbering.
In principle the warp threads are caused to run in twos by making them
take twists upon carriage threads, which remain straight. These carriage
threads cross each other at A, B, C, D, E, and other points, as indicated in

page_text: Figures 1 and 2 of the annexed Diagrams, and their twists are maintained
by the aid of the following numbering
Suppose eight running threads actuated by bars Nos. 1, 2, 3, 4, 5, 6,
7, 8, it is always necessary to cause one or other of the first four bars to
work with one or other of the last four. Suppose any other number of
running threads the principle is the same, that is to say, the bars are divided
into the first half, and the second half, and work in pairs, one bar of the first
half with one of the second. The threads, which remain straight, are like
the running threads grouped in pairs, and should like these latter intertwine.
These straight threads are composed of two carriage threads, as indicated in
Figures 3 and 4, or of a warp thread and a carriage thread, as indicated in
Figures 5 and 6. In the former case the two carriage threads are twisted
by the aid of the running warp threads; in the latter case there are straight
warp threads, either from the first bars or from the second, according to
the running threads. More or less twists may be given to the straight threads
or to the running threads. In the Diagrams the carriage threads are shown
red, and the warp threads black.
The following tables show the takings of the inacuerd

page_text: The main features of the Invention are the system or mode of numbering
the running threads, by the aid of which system the warp threads inter-
twine while maintaining their twists; and the arrangements of the bars which
permit of realizing this numbering with the view of manufacturing lace called
"Paris point."
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Clinton Edgcumbe Brooman in the Great Seal Patent Office
on the 13th April 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CLINTON
EDGCUMBE BROOMAN, of the Firm of Robertson, Brooman, and Company, of
166, Fleet Street, in the City of London, Patent Agents, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of October, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Clinton Edgcumbe Brooman, Her special licence that I, the said Clinton
Edgcumbe Brooman, my executors, administrators, and assigns, or such others
as I, the said Clinton Edgcumbe Brooman, 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 "Im-
PROVEMENTS IN THE MANUFACTURE OF LACE," (communicated to me from abroad
by Désiré Sival and Leon Sival, both of Roubaix, France, upon the condition
(amongst others) that I, the said Clinton Edgcumbe Brooman, ny 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.
NOW KNOW YE, that I, the said Clinton Edgcumbe Brooman, 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, reference being had to the Drawing hereunto
annexed, that is to say :-

page_text: This Invention relates to "Paris point," and consists in particular
arrangements of the bars of lace machines, constituting a new system of
numbering.
In principle the warp threads are caused to run in twos by making them
take twists upon carriage threads, which remain straight. These carriage
threads cross each other at A, B, C, D, E, and other points, as indicated in
Figures 1 and 2 of the annexed Diagrams, and their twists are maintained
by the aid of the following numbering :-
Suppose eight running threads actuated by bars Nos. 1, 2, 3, 4, 5, 6, 7, 8, it
is always necessary to cause one or other of the first four bars to work with one
or other of the last four. Suppose any other number of running threads the
principle is the same, that is to say, the bars are divided into the first half
and the second half, and work in pairs, one bar of the first half with one of
the second. The threads which remain straight are like the running threads
grouped in pairs, and should like these latter intertwine. These straight
threads are composed of two carriage threads, as indicated in Figures 3 and 4,
or of a warp thread and a carriage thread, as indicated in Figures 5 and 6.
In the former case the two carriage threads are twisted by the aid of the
running warp threads; in the latter case there are straight warp threads,
either from the first bars or from the second, according to the running threads.
More or less twists may be given to the straight threads or to the running
threads. In the Diagrams the carriage threads are shewn in dotted lines, and
the warp threads in full lines. The tables annexed to the Diagrams shew
the takings of the jacquards.
What I claim as the Invention is,-
First. The system or mode herein-before explained of numbering the running
