I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN SWORD BAYONETS AND OTHER SWORDS," (communicated to
me from abroad by François Jules Manceaux, of Paris,) to be as follows:―
This Invention consists in constructing sword bayonets and other swords of a
triangular shape, with the flat of the blade hollowed out or grooved longitudinally,
or in a direction parallel with the back, and without a central core (noyau), so
as to form a blade hollow and of equal thickness, possessing great rigidity with
little weight.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHard
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of November, 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 me, the
said Richard Archibald Brooman, Her special licence that I, the said Richard
Archibald Brooman, my executors, administrators, and assigns, or such others
as I, the said Richard Archibald 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
"IMPROVEMENTS IN SWORD BAYONETS AND OTHER SWORDS," (communicated to me
from abroad by François Jules Manceaux, of Paris,) upon the condition
(amongst others) that I, the said Richard Archibald Brooman, 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.
NOW KNOW YE, that I, the said Richard Archibald 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 Drawings hereunto
annexed, that is to say:-
This Invention consists in constructing sword bayonets and other swords
with the blade of a triangular shape, hollowed out or grooved longitudinally,
and without a central core, in order to form a blade possessing great rigidity
with little weight, compared with blades as heretofore manufactured.
Figure 1 of the accompanying Drawings is a section of the steel prepared
for forming the triangular blade of sword bayonets and other swords, according
to this Invention, taken at the base of the blade; Figure 2 is a similar view

page_text: taken near the point thereof; Figures 3 and 4 are respectively sections at the
base and near the point of the blade in its finished state. The metal is
worked by the processes known to sword cutlers, to bring it into the form
shewn in the Drawings. Figures 5, 6, and 7 are elevations, shewing three
different views of a bayonet complete; Figure 8 is an elevation shewing one
of the finished blades fixed to a sword handle.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim, manufacturing
sword bayonets and other swords with triangular grooved blades of the form
herein-before described and represented in the accompanying Drawings.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Fifteenth day of May, One thousand
eight hundred and sixty-one.
