TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TAYLOR, of Newport Pagnell, in the County of Buckingham, Soda Water
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day. of October, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Taylor, Her special licence that I, the said William
Taylor, my executors, administrators, and assigns, or such others as I, the
said William Taylor; 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 JOINTS OR CONNECTIONS FOR METAL AND OTHER PIPES AND TUBES," upon the
condition (amongst others) that I, the said William Taylor, 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 William Taylor, do hereby declare the
nature of the 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 thereof, reference being had to the Drawings hereunto annexed,
that is to say:-
My Invention consists in forming a flange or collar on the ends of pipes and
tubes, in making undercut grooves, two, three, or more in the collars, and in
the employment of dovetail cottars formed with a head at one end, and with a
slot or groove near the other for the reception of a key, which cottars slide
into the grooves and are tightened up by the keys being driven into the
slots.
Figure 1 of the accompanying Drawings is a plan of portions of two pipes
united in this manner. a is the flange on the pipe b; c is the flange on the
pipe d; e, e, are the undercuts in the flanges, more clearly seen in the end

page_text: views Figures 2 and 3; f, f, are the dovetail cottars, detached views of one of
which are given at Figures 4 and 5, with heads 9, 9, and slots h, h, for the
reception of the wedges or keys i, i. Sometimes I insert a washer of
washers k, k, between the pipes, in which case they have undercuts in them
to correspond with those on the flanges. Where pipes are required to be
curved at the joints or connections, a space is left on one or other side of the
flanges of the pipes according to the direction of the curve, into which spun
yarn or other suitable packing is placed, and the whole is tightened up as
before stated by keys. Portions of two pipes joined together in this manner
are shown at Figure 6. Packing is inserted between the flanges a and c, and
according to the curve required, so the thickness of the packing is regulated.
Sometimes I run in molten lead over and round the packing.
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, forming joints or
connections for metal and other pipes and tubes, by making undercut grooves
in the flanges at the ends of the said pipes or tubes for receiving dovetail
cottars, which are secured and tightened by keys or wedges, substantially
in manner herein-before described and illustrated in the accompanying
Drawings.
In witness whereof, I, the said William Taylor, have hereunto set my
hand and seal, this Twenty-fourth day of April, One thousand eight
hundred and sixty-two.
WILLIAM TAYLOR. (L.S.)
