Sealed the 1st September 1865, and dated the 9th March 1865.
PROVISIONAL SPECIFICATION left by the said Victor Delperdange at
the Office of the Commissioners of Patents, with his Petition, on the
9th March 1865.
I, VICTOR DEL PERDANGE, of the City of Brussels, in the Kingdom of
Belgium, Engineer, do hereby declare the nature of the said Invention for
"AN IMPROVED METHOD OF CONNECTING TOGETHER TUBES OR PIPES USED FOR
CONVEYING GAS AND WATER, AND FOR OTHER PURPOSES," to be as follows:-
This Invention relates more particularly to an improved method of con-
necting branch pipes to main pipes.
The modes heretofore commonly practised for effecting this has been either
by flanges bolted together or by sockets filled with lead or cement for large
pipes, and for small pipes by cutting a screw on the branch pipe and screwing
same into a screwed hole formed in the main pipe.
By adapting the above methods great difficulty is experienced in dis-
connecting, pipes thus connected together. This objection I propose to
obviate in the following manner:-For example, I form an oblong, oval, or
Price 811

page_text: other shaped long hole in the main pipe, and spread or widen that end of the
circular branch pipe which is to be connected to the main pipe until it assumes
a form somewhat similar to the aforesaid hole in the main pipe. This end of
the branch pipe has a screw cut about it, and carries a nut and loose metal
washer, and resting upon this washer another washer of vulcanized india-
rubber or other suitable elastic material. To connect the branch pipe thus
fitted and formed to the main pipe I insert the end of the branch pipe into
the aforesaid long hole in the main pipe and turn the branch round one
quarter of an entire turn, then tighten the nut against the washers and hole
in the main pipe. By these means the enlarged end of the branch pipe, being
crosswise of the narrow part of the hole in the main pipe, may be securely
connected thereto and disconnected therefrom at will.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Victor Delperdange in the Great Seal Patent Office on
the 9th September 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, VICTOR
DELPERDANGE, of the City of Brussels, in the Kingdom of Belgium, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of March, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Victor Delperdange. Her special licence that I, the said
Victor Delperdange, my executors. administrators, and assigns, or such
others as I, the said Victor Delperdange, 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
"AN IMPROVED METHOD OF CONNECTING TOGETHER TUBES OR PIPES USED FOR
CONVEYING GAS AND WATER, AND FOR OTHER PURPOSES," upon the condition
(amongst others) that I, the said Victor Delperdange, 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

page_text: NOW KNOW YE, that I, the said Victor Delperdange, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say:
This Invention relates more particularly to an improved method of con-
necting branch pipes to main pipes.
The modes heretofore commonly practised for effecting this have been
either by flanges bolted together or by sockets filled with lead or cement for
large pipes, and for small pipes by cutting a screw on the branch pipe and
screwing the same into a screwed hole formed in the main pipe.
By adopting the above methods great difficulty is experienced in dis-
connecting pipes thus connected together. This objection I propose to
obviate in the following manner:-For example, I form an oblong, oval,
or other shaped long hole in the main pipe, and spread or widen that end
of the circular branch pipe which is to be connected to the main pipe
until it assumes a form somewhat similar to the aforesaid hole in the main
pipe. This end of the branch pipe has a screw cut about it, and carries
a nut and loose metal washer, and resting upon this washer another washer
of vulcanized india-rubber or other suitable elastic material. To connect
the branch pipe thus fitted and formed to the main pipe I insert the end
of the branch pipe into the aforesaid long hole in the main pipe and turn
the branch round one quarter of an entire turn, then tighten the nut
against the washers and hole in the main pipe. By these means the
enlarged end of the branch pipe, being crosswise of the narrow part of the
hole in the main pipe, may be securely connected thereto and disconnected
therefrom at will.
And in order to explain my said Invention as completely as possible, I now
proceed to describe the best means I am acquainted with for carrying the
same into practical effect, reference being had to the illustrative Sheet of
Drawings hereunto annexed, and to the numeral figures and letters of reference
marked thereon respectively, as follows:-.
DESCRIPTION OF THE SHEET OF DRAWINGS.
Figure represents a portion of a main pipe with an elongated hole
therein for connecting a branch pipe thereto according to my said Invention:
Figure 2, a similar view of the pipe, with branch pipe and connection
attached; Figure 3, a transverse section of main pipe, shewing connexions

page_text: and portion of branch pipe in side elevation; Figure 4. a transverse section
through the line A, B. at Figure 2; Figure 5. a section through the line C. D,
at Figure 2. the branch pipe being represented in elevation. At each of the
foregoing Figures I employ similar letters of reference to denote corresponding
parts in so far as such parts appear or can be seen at each of such said
Figures respectively.
A marks a portion of a main pipe of metal or other material; B. an
elongated hole or opening formed therein C is a branch pipe which may
be of metal or other material; if of metal a screw is cut about it, and the
end that is intended to be connected to the main pipe is spread out to
assume a somewhat similar shape to the hole B in the main pipe, or a
flange of that shape may be screwed on to the end of the branch pipe, and,
if necessary, brazed or soldered thereonio; and in the case of branch pipes
made of vitreous or plastic or other materials than metal; the aforesaid
flange piece may be affixed thereto by cement or other suitable adhesive
material. I propose also to employ a screw nut D, metal washer E, and
another washer F, formed of vulcanized india-rubber or other suitable elastic
material, these parts or pieces being placed on the branch pipe previous to
the flange piece E being affixed thereto, or the end of said pipe being spread
out as before stated.
I now proceed to describe the mode of connecting the aforesaid branch
to the main pipe as follows:-The enlarged end or flanged part of the
branch pipe C is inserted into the hole B in the main pipe, after which
the branch pipe is turned round about a quarter of an entire revolution,
so as to bring the long part of the flange or enlarged part of the branch
pipe across the narrowest part of the hole in the main pipe, and being held
in this position the nut D is screwed tightly down upon the washer E,
by which the elastic washer F will be squeezed tightly against the main
pipe and cause the elastic material to fill the hole B in the main pipe A and
washer F, somewhat after the manner represented at Figure 5, thereby
forming a perfectly air-tight joint or junction of the branch pipe with the
main pipe A.
:
I would here remark that the shape of the hole in the main pipe is
immaterial and may be of various forms, such as square, triangular, oval, or
other form, so long as the shape be such as to enable the flanged or enlarged
part of the branch pipe when turned one quarter round to hold firmly against
the inside of the hole A, when said branch pipe is screwed thereio as above
stated.
Having now fully described and set forth the nature and object of my

page_text: said Invention for "An Improved Method of Connecting together Tubes
or Pipes used for Conveying Gas and Water, and for other Purposes," together
with the best means I am acquainted with for carrying the same into practical
effect, I would remark in conclusion that I hereby declare my Invention to
consist in, and I claim, the mode set forth, described, and represented, of
connecting branch pipes to main pipes as above stated.
In witness whereof, I, the said Victor Delperdange, have hereunto set
my hand and seal, this First day of September, in the year of our
Lord One thousand eight hundred and sixty-five.
