Complete Specification Accepted, 7th Sept. 1888
1, GEORGE WILLIAM HARGREAVES BROGDEN, of Gresham House, Old Broad Street,
in the city of London, Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an improved method of connecting together pipes and
tubes whereby the connections can be effected in a better, quicker and simpler manner
than hitherto.
According to my invention the pipes to be connected are formed with flanges at
their ends, and I provide collars or rings formed in sections so that they can be placed
on the pipes when in position behind each flange the two complete rings or collars of
two pipe ends being then bolted together the sections of the collars being so placed
that the joints shall overlap. Any suitable packing can be used between the flanges
of the pipes.
In some cases the sections of the collars are formed so that they can be overlapped,
thereby allowing two bolts to hold one complete ring on each pipe the bolts for this
purpose being provided with a collar.

Improvements in the Method of Connecting Pipes and Tubes.
I, GEORGE WILLIAM HARGREAVES BROGDEN, of Gresham House, Old Broad Street,
in the city of London, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—
My invention relates to pipes or tubes and to an improved method of connecting
or uniting the same; and it consists chiefly in the employment of loose collars or
rings which are formed in sections, so that they can be readily placed upon the ends
of the pipes or tubes to be connected, the said collars or rings being adapted to bear
against Hanges or projections on the said pipes or tubes and to be held together by
bolts or their equivalents.
In the accompanying drawings
Figure 1 is an end elevation illustrating the arrangement of the collars or rings for
connecting two adjacent pipes or tubes, and
Figure 2 is a side elevation of the same.
Figure is a view showing the sections of the flange detached, and,
Figure 4 is a view similar to Figure 2, but showing the collars or rings disconnected
from each other.
Figures 5 and 6 are views similar to Figures 1 and 2 respectively illustrating
modification of my invention.
AL
a, b indicate the adjacent end portions of two pipes or tubes to be connected, c, d the
sectional collars or rings, and e, e, f,f the bolts or studs.
9, are flanges which are formed upon the ends of the pipes a, b respectively and
which serve to maintain the collars or rings upon the pipes, and is a packing ring
which is placed between the adjacent tubes.
shown in Figure 3
Each of the collars or rings c, d is formed in two sections as
and one end of each section has advantageously formed integral with it a tongue i
against which the plain end of the other section of the collar can lie, as shown most
clearly in Figures 2 and 4 so that the face of the collar in contact with the flange will
be close to the latter.
The sections of each collar are preferably connected together by the bolts which
also serve to unite adjacent collars. As shown in the drawing each of the said bolts
is provided with a collar; between which and a nut, the tongue of one section and the
adjacent end of the other section of each collar are clamped, so that the said sections
are rigid relatively to each other.
In jointing two adjacent pipes the collars are first of all applied to the respective
tubes and then moved towards each other so that the studs e of the collar e enter holes
between the studs of the collar d and vice versa, the whole being finally secured by
nuts, as indicated in Figure 2.

page_text: I wish it understood that I do not confine myself to the construction shown in the
drawing as it is obvious that each collar may be formed in more than two sections if
desired and that other means than those described may be employed for uniting the
several sections of each collar together. For instance, as shown in Figures 5 and 6,
the tongues at the ends of the sections are dispensed with, the bolts for uniting the
sections being so placed that each of them passes through a hole in the centre of one
section of one collar and through a hole formed partly in each of the adjacent ends
of the sections of the other collar.
The chief advantage of my invention is that by the employment of loose collars
much less room is required for the stowage of a given number of pipes or tubes for
transport than for the same number provided with flanges of 'the ordinary
construction.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The method of joining or connecting pipes or tubes by means of loose collars or
rings formed in two or more sections and adapted to bear upon small flanges or lugs
upon the ends of the pipes or tubes to be joined.
2. The method of joining or connecting pipes or tubes, substantially in the manner
hereinbefore described and as illustrated in the accompanying drawing.
3. The manufacture and use of loose collars or rings for joining or connecting pipos
or tubes, substantially as herein before described.
