IMPROVEMENTS IN CONNECTING GAS AND OTHER PIPES
Year: 1860

page_text: LETTERS PATENT to Alphonse René Le Mire Normandy, of Odin
Lodge, King's Road, Clapham Park, in the County of Surrey, for the
PROVISIONAL SPECIFICATION left by the said Alphonse René Le Mire
Normandy at the Office of the Commissioners of Patents, with his
Petition, on the 21st July 1860.
I, ALPHONSE RENÉ LE MIRE NORMANDY, of Odin Lodge, King's Road,
Clapham Park, in the County of Surrey, do hereby declare the nature of the
Invention for "IMPROVEMENTS IN CONNECTING GAS AND OTHER PIPES," to be as
follows:-
This Invention has for its object improvements in connecting gas and other
pipes. The pipes to which I apply my improved joint I make plain from
end to end, that is to say, without sockets, and when two such pipes are laid
end to end, I slip over them, to the point where the ends meet or come oppo-
site each other, a short cylinder of slightly larger diameter than the pipes to
be connected. This short cylinder is made at its two ends with sockets or
recesses of larger diameter than the other parts of the cylinder, and it has
also flanges at its ends. Into the sockets or recesses rings of vulcanized
india-rubber or other suitable packings are introduced, and over these filling
pieces or rings of metal are placed which enter the sockets or recesses. These
filling pieces are furnished with flanges, by means of which the said pieces are
forced down upon the packing, screw bolts being employed to draw the flanges

page_text: on the filling pieces up to the flanges on the cylinder. Other means may be
employed for forcing the filling pieces or rings on to the packing, or other
means of expanding the packing, and pressing it firmly in contact both with
the pipes and the covering cylinder may be resorted to.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alphonse René Le Mire Normandy in the Great Seal Patent
Office on the 19th January 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALPHONSO
RENÉ LE MIRE NORMANDY, of Odin Lodge, King's Road, Clapham Park, in
the County of Surrey, send greeting.
WHEREAS Her most Excellent-Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of July, 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 Alphonse René Le Mire Normandy, Her special licence that I,
the said Alponse René Le Mire Normandy, my executors, administrators, and
assigns, or such others as I, the said Alphonse René Le Mire Normandy, 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 CONNECTING
GAS AND OTHER PIPES," upon the condition (amongst others) that I, the said
Alphonse René Le Mire Normandy, 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 Alphonse René Le Mire Normandy,
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 :-
This Invention has for its object improvements in connecting gas and other
pipes. The pipes to which I apply my improved joint I make plain from end
to end, that is to say, without sockets, and when two such pipes are laid end

page_text: to end, I slip over them to the point, where the ends meet or come opposite
each other, a short cylinder of slightly larger diameter than the pipes to be
connected. This short cylinder is made at its two ends with sockets or recesses
of larger diameter than the other parts of the cylinder; and it has also
flanges at its ends. Into the sockets or recesses rings of vulcanized india-
rubber or other suitable packings are introduced, and over these filling pieces
or rings of metal are placed which enter the sockets or recesses. These filling
pieces are furnished with flanges, by means of which the said pieces are forced
down upon the packing, screw bolts being employed to draw the flanges on the
filling pieces up to the flanges on the cylinder; other means may be employed
for forcing the filling pieces or rings on to the packing, or other means of
expanding the packing and pressing it firmly in contact both with the pipes
and the covering cylinder may be resorted to.
And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawing hereunto
annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 shews a longitudinal section and a plan of the ends of two pipes,
connected together in the manner above described.
A, A, are the ends of the pipes; B is a short cylinder, slipped over them to
the point where the ends meet or come opposite each other; it is made with
flanges C, C, and sockets, as is shewn; D, D, are packing rings, fitted into
the sockets; F, F, are pieces employed to compress the packing, and cause it
to fit tightly to the pipe A, and also to the socket on the short cylinder B;
the pieces consist of filling pieces or rings entering the sockets over the
packing rings, and of flanges to receive the bolts G, G, which draw the said
flanges towards the flanges C.
Figure 2 shews a slight modification of the arrangement shewn at Figure 1,
the rings or filling pieces being formed on the short cylinder B, and the sockets
formed in the piece F.
In witness whereof, I, the said Alphonse René Le Mire Normandy, have
hereunto set my hand and seal, this Seventeenth day of January, in
the year of our Lord One thousand eight hundred and sixty-one.
