IMPROVE- MENTS IN CLOSING POWDER CANISTERS AND OTHER VESSELS
Year: 1863

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, Patent Agent, for the Invention of "IMPROVE-
MENTS IN CLOSING POWDER CANISTERS AND OTHER VESSELS."-A commu-
nication from abroad by Joseph Sagnes, of Toulon, France.
Sealed the 16th February 1864, and dated the 22nd August 1863.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on the
22nd August 1863.
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 CLOSING POWDER CANISTERS AND OTHER VESSELS," to be
as follows:-
This closing is effected by means of cross bars, which press upon a
movable cover, the tightening being obtained by a double screw thread acting
inversely spon the cross bars and upon the cover.
The Invention will be best understood on reference to the accompanying
Drawings, in which Figure 1 is a plan of the fastening, and Figure 2 a
section on the broken line A, B, C. The rim A of the canister is formed
with three projections or claws a, and two lugs 6, forming a hinge, and pierced
with a cylindrical hole; they are riveted and soldered, or otherwise fixed to
the canister. B is a cover, having a groove on its lower edge to receive felt
or other packing c; it is formed with hooks e round its socket d, and is

page_text: united to the rim A by a hinge f, having a hole o elliptical vertically, which
is traversed by a pin g with a head h. This head has a notch therein for the
passage of the part t of one of the cross bars C. Each of the cross bars C
has a hook K at its extremity; around and below the socket are hooks n
and a pin i. D is a central spindle; with mortices P at its upper part, it is
provided with a pin m. The spindle D is formed with a right-handed thread to
take into the threaded socket 7 of the cross bars, and with a left-handed thread
to take into the threaded socket 7, which is fixed in the socket of the cover
by four small screws q. A key is made to fit on the spindle by turning the
key to the left, the spindle by the double action of its screw threads loosens both
the cover and the cross bars from the rim, and consequently the joint formed
by the packing: In this movement the pin m of the spindle meeting the
pini of the cross bars, carries it with it, and to secure the cross bars when the
cover is opened, one of the extremities is engaged into the notched head of
the pin of the hinge, and at the same time, to stop the unscrewing, I make
the hooks n engage under the corresponding hooks e of the cover. This is
the position represented in the Drawings.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 22nd February 1864.
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 Twenty-second day of August, in the year of our
Lord One thousand eight bundred and sixty-three, in the twenty-seventh
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 CLOSING POWDER
CANISTERS AND OTHER VESSELS," (communicated to me from abroad by Joseph

page_text: Sagnes, of Toulon, France,) 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 closing is effected by means of cross bars, which press upon a cover,
the tightening being obtained by a double screw thread, acting inversely upon
the cross bars and upon the cover.
The rim A of the
6, forming a hinge,
soldered, or other-
on its lower edge
The Invention will be best understood on reference to the accompanying
Drawings, in which Figure 1 is a plan of the fastening, and Figure 2 a
section on the broken line A, B, C, of Figure 1; Figure 3 is a section of the
cross bars through the line D, E, of Figure 2; Figure 4 shews the key for
tightening and loosening the cover and the cross bars.
canister carries three projections or claws a, and two lugs
and pierced with a cylindrical hole; they are riveted and
wise fixed to the canister. B is a cover, having a groove
to receive felt or other packing c. It is furnished with hooks e round its
socket d, and is united to the rim A by a hinge f, having an elliptical hole o,
which is traversed by a pin 9 with a head h. This head has a notch therein
for the passage of the part t of one of the cross bars C. Each of the cross
bars C has a hook k at its extremity; round and below the socket / are
hooks n and a pin i. D is a central spindle, with mortices P at its upper
part, it is provided with a pin m. The spindle D is formed with a right-
handed thread to take into the threaded socket 7 of the cross bars, and with
a left-handed thread to take into the threaded socket r, which is fixed in the
socket of the cover by four small screws q. E, Figure 4, is a key made to
fit on to the spindle; by turning the key to the left, the spindle D, by the
double action of its screw threads, loosens both the cover and the cross bars
from the rim, and consequently the joint formed by the packing. In this
movement the pin m of the spindle meeting the pin i of the cross bars, carries
it with it, and to secure the cross bars when the cover is opened, one of the
extremities t is engaged into the notched head of the pin of the hinge, and

page_text: at the same time to stop the unscrewing, I make the hooks n engage under
the corresponding hooks e of the cover; this is the position represented in
the Drawings. By turning the key to the right as soon as the cross bars
have, by being moved by hand, been disengaged from the central hooks and
the head of the pin of the hinge, and as soon as the hooks k of the cross bars
are engaged into the hooks a of the rim, the spindle D presses on the centre,
the cover B is pushed downwards, and the cross bars C upwards. This
'contrary pressure, acting on the edges of these parts, tightens them simul-
taneously in opposite ways against the rim A, and forms, with the packing c,
a hermetic joint.
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, closing powder
Canisters and other vessels substantially by the means and in manner herein-
before described and illustrated in the accompanying Drawings.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Twenty-second day of February, One
thousand eight hundred and sixty-four.
