page_text: LETTERS PATENT to Thomas Seaville Truss, of 118, Fenchurch Street,
in the City of London, Civil Engineer, for the Invention of "IMPROVE-
MENTS IN THE CONSTRUCTION OF PIPES, AND IN THE MODE OF JOINING THE
SAME FOR THE TRANSMISSION OF GAS, WATER, STEAM, AIR, AND OTHER
FLUIDS."
Sealed the 10th May 1867, and dated the 14th November 1866.
PROVISIONAL SPECIFICATION left by the said Thomas Seaville Truss at
the Office of the Commissioners of Patents, with his Petition, on the
14th November 1866.
I, THOMAS SEAVILLE TRUSS, of 118, Fenchurch Street, in the City of
London, Civil Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF PIPES, AND IN THE MODE OF JOINING
THE SAME FOR THE TRANSMISSION OF GAS, WATER, STEAM, AIR; AND OTHER FLUIDS,"
to be as follows:-
This Invention consists in the construction of pipes with a circular or
conical formed groove round the outer surface of the pipes, at or adjoining
their ends, and in the construction of a band in one or more parts to embrace
the ends of the pipes when they are brought together to be jointed or con-
nected, the several ends or junctures of the band being secured to each other
by screw bolts and nuts or other suitable appliances; the interior of the band

page_text: is constructed with two raised circular or conical formed beads or projections
on the circumferance at or adjoining the outer edges, which beads or pro-
jections fit into the grooves round the ends of the pipes, and between the beads
or projections round the interior of the band and the grooves round the ends
of the pipes packing is applied suitable to make a gas, water, steam, or air-
tight joint. The band being secured round the ends of the pipes by the
several ends or parts of the band being held together by screw bolts and nuts
passing through ears or projections at the ends thereof provided for such
screw bolts and nuts, the several ends of the band being brought together
by the screw bolts, the packing between the beads or projections round
the interior of the band and the grooves round the ends of the pipes is
compressed as required to make a tight joint, and the joint so constructed
forms a flexible joint, allowing the pipes so jointed or connected to be
moved without imparing the soundness of the joint. The packing I chiefly
use for the joint is india-rubber. For some purposes I employ pipes without
any grooves round their ends, using the ordinary plain pipes, and for some
purposes I' construct the bands with more than two beads round their interior,
as also the pipes with more than one groove at or adjoining their ends; I also
groove the beads round the interior of the band and the grooves round the
ends of the pipes.
As my said Invention is capable of various modifications without departing
from the principle thereof I do not restrict myself to material or dimensions
or to the precise form of the several parts thereof.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Seaville Truss in the Great Seal Patent Office on the a
14th May 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
SEAVILLE TRUSS, of 118, Fenchurch Street, in the City of London, Civil
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Thomas Seaville Truss, Her special licence that I, the said Thomas Seaville
Truss, my executors, administrators, and assigns, or such others as I, the

page_text: :
said Thomas-Seaville Truss, 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 THE CONSTRUCTION OF PIPES, AND IN THE. MODE OF JOINING
THE SAME FOR THE TRANSMISSION OF GAS, WATER, STEAM, AIR, AND OTHER FLUIDS,"
upon the condition (amongst others) that I, the said Thomas Seaville, Truss,
my exécutors 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 Inventions and in what manner the same was to be per-
formed; 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 Thomas Seaville Truss, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed; to be particularly described and ascertained in and by the
following. statement (that is to say), reference being had to the Drawings
hereunto annexed:-
My said improvements consist in the construction of pipes with a circular
or conical-formed groove round the outer surfaces of the pipes at or adjoining
their ends, and in the construction of a band to embrace the ends of the pipes"
when they are brought together to be jointed or connected: The band is
constructed of one piece or in several parts or segments, the several ends of
the same forming ears or projections for screw bolts to pass through in order
to secure together the ends or several segments or: parts into which the band
is divided. The interior of the band is constructed with two raised circular
or conical-formed beads or projections on the internal circumference at. or
adjoining the outer edges, which beads or projections fit into the grooves
rounds the ends of the pipes. Between the surfaces of the grooves on the ends
of the ends of the pipes and the beads or projections in the interior of the band
india-rubber or any other material suitable for making gas, water, steam, and
air-tight joints is applied; then by drawing the ends of the band or the several
parts or segments together by the screw bolts passing. through the ears or
projections formed, at their several ends, the required pressure is applied upon
the joint-making material to make a gas, water, steam or air-tight joint, which
joint when made is a flexible joint allowing. of the oscillation of the pipes
without impairing the tightness of the joint..

page_text: '
In order that the nature of my said improvements and in what manner the
same are to be performed. may. be more fully understood, I will proceed to
describe the several Figures in the Sheet of Drawings hereunto annexed.
Figure 1. is a longitudinal section of the ends of two pipes connected
together with a band formed of one piece in the manner herein-before!
described; Figure 2 is a cross section of the same taken at the line C in
Figure 1; Figure 3 is an external longitudinal view, and Figure 4 is an end
view of the same. A, A, are the ends of two pipes; a, a, a, a, are the grooves
on the external surfaces of the ends thereof;- B, B, is the band embracing the
ends of the pipes A, A, and b, b, b, b, are the raised beads or projections on the
internal circumference of the band B, B; c, c,. are the ears or lugs formed at
the ends of the band for the screw bolt d to pass through, and e, e, e, e, is the
joint-making material placed between. the surfaces of the groove a, a, a, 'a, on
the ends of the pipes A, A, and the surfaces of the beads or projections b, b, b, b,
on the internal circumference of the band B, B.
Figure 5 is an.. end view of the joint shewing the band B, B, B, B, con-
structed in several parts or segments, and Figures 6, 7, and 8 are longitudinal
sections of a few modifications of the foregoing arrangements, shewing the
grooves on the ends of the pipes and the raised beads or projections on the
internal circumference of the band grooved in themselves; and they are
marked with the like letters of reference as Figures 1 to 5 inclusive.
To make the joint so constructed I proceed by bringing the ends of the
pipes together; I then place the joint-making material upon the ends of
the pipes; I then apply the band upon the same, and draw the ends of the
band or the several parts or segments together by the screw bolts until the
pressure. requisite to make a tight joint is applied upon the joint-making
material.
As my said improvements are capable of various modifications without
:departing from the principal thereof I do not restrict myself to one groove on
the ends of the pipes, or to two beads or projections on the internal circum-
ference of the band, or to materials or dimensions, or to the precise form of the
several parts thereof.
Having now described the nature of my said improvements, and in what
manner the same are to be performed, I declare that I claim as my Invention
the construction of flexible joints for connecting or joining together of pipes
or tubes for the transmission of gas, water, steam, air, or other. fluids by
_means of a band in one piece or divided into several parts or segments with
raised beads or projections on the internal circumference to operate upon

page_text: joint-making material applied in the grooves on the ends of pipes or upon
pipes having plain surfaces; I also claim the construction of pipes with
grooves at their ends to be used and operated upon as herein-before described..
In witness whereof, I, the said Thomas Seaville Truss, have hereunto
set my hand and seal, this Fourteenth day of May, in the year of our
Lord One thousand eight-hundred and sixty-seven.
