Improvements in or connected with Making Good Damaged Pipes,
and Appliances therefor.
I, CHARLES SHENTON DU SAUTOY, of Linden, Denzil Avenue, Southampton,
in the County of Hampshire, Engineer, do hereby declare the nature of this
invention to be as follows:--
The meaus I employ in the carrying out of my invention consists of an apparatus
in the form of a clip or coupling, made in two or more parts or sections, and having
a stuffing box or boxes, the parts or sections are fitted together over the damaged
part of the pipe and fastened by bolts, screws, hooks, or like devices. The clip
or coupling is made of any required shape to suit any sized pipe and to fit either
over the flange of the pipes embracing the body of the pipe or on the flange
embracing the body, or in such a way as to cover and make good the fractured or
leaky part.
For example, should a pipe or pipes crack or break at the neck of the flange or
flanges, I apply the clip or coupling so as to cover the fracture, and I thereby
make good the damaged part, and render the pipe as efficient and reliable as it was
before the damage took place.
In like manner a fracture in the body, whether in a straight part or a bent part
of a pipe, can be made good by the use of a clip or coupling according to this
invention.

COMPLETE SPECIFICATION.
Improvements in or connected with Making Good Damaged Pipes,
and Appliances therefor.
I, CHARLES SHENTON DU SAUTOY, of Linden, Denzil Avenue, Southampton,
in the County of Hampshire, Engineer, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described in and by the following statement :-
The means I employ in the carrying out of my invention consist of an apparatus
in the form of a clip or coupling, made in two or more parts or sections, and having
a stuffing box or boxes, the parts or sections being fitted together over the
damaged part of the pipe, and fastened by bolts, screws, studs, hooks, or like
devices. The clip or coupling is made of any required shape to suit any sized
pipe and to fit either over the flange of the pipes embracing the body of the pipe,
or on the flange embracing the body, or in such a way as to cover and make good
the fractured or leaky part.
For example, should a pipe or pipes crack or break at the neck of the flange or
flanges, I apply the clip or coupling so as to cover the fracture, and I thereby
make good the damaged part, and render the pipe as efficient and reliable as it was
before the damage took place.
In like manner a fracture in the body, whether in a straight part or a bent part
of a pipe, can be made good by the use of a clip or coupling according to this
invention

page_text: In the examples of appliances for making good damaged pipes according to this
invention illustrated in the accompanying drawings,
Figure 1 is a part sectional elevation, and Figure 2 an end view of one con-
struction under the invention.
Figure 3 is a part sectional elevation of a modification of the invention; and
Figure 4 shows in part longitudinal section a further modification.
Figure 5 is a part sectional elevation of a modification in duplex form according
to the invention."
In the various figures of the drawings like letters are used to denote like or
corresponding parts wherever they occur.
With reference to Figures 1 and 2, the coupling or clip consists of a divided
chest or box comprising two parts a, with Hanges b, which flanges are bolted
together as shewn. At one end of this chest or box an annular recess is provided
on its interior, in which fits a suitable pliable packing c, adapted to make joint
between the chest or box and the flange d¹ of the pipe d, to which it is applied.
At the other end of the chest or box a a stuffing box e, adapted to receive stuffing
for making a joint with the pipe is provided, its gland e¹ being in two parts bolted
together in the manner of the chest or box a, as shown. Thus the stuffing box
makes a joint with the exterior of the pipe f, whilst the joint of the chest or box
with the pipe d is made through the packing c and flange of said pipe.
The space within the chest or box between these packings constitutes a closed
space, and the pipe f, or the joint of this pipe with the flange d', is assumed to be
damaged and enclosed within this space; thus whatever fluid escapes from the
pipes into said space is prevented from escaping from the chest or box by the
packings specified. And conversely, if the pressure within the pipes d, fwere
below that of the atmosphere, the appliance just described would prevent the
entrance of the atmosphere into the pipes.
The modification in Figure 3 consists in making the joint between the flange d¹
of the pipe d and the chest or box a by providing the internal surface of said chest
or box, and the external ring of the flange d' with a thread, and screwing the chest
or box on to the flange; otherwise than in this respect this construction is similar
to that set forth with reference to Figures 1 and 2.
In the modification shewn in Figure 4 the chest or box a is provided with a
cover a (which is also divided and connected together by flanges) fitting onto the
flange on a, and secured on the end of said chest or box by bolts; whilst the other
end of the chest or box is secured to the metal of the part d' by studs and nuts d²,
passing through an inner flange of said chest or box a, and the flange f' of the
pipe f
In this arrangement the box or chest encloses a part of the pipe lying between
the flange and a certain length up such pipe, wherein the damaged part exists.
The pipe shown in the figures so far described is represented as a copper or
other wrought or equivalent metal pipe, having its flange brazed or equivalently
fastened to it, as shown.
In Figure 5 I show two copper or other wrought or equivalent metal pipes f
having attached flanges f, as just specified. The appliance herein shown is of
duplex form and adapted to enclose the whole coupling of the pipes ff, and is
provided at each end with a stuffing box e and gland e¹, as above set forth.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, it is to be understood
that the invention is not confined to the construction of parts set forth with
reference to the drawings, as these constitute only so many examples of the
application of the invention; and that therefore it may be modified and differently
arranged and adapted to suit the varying conditions of the application without
departing from the main or essential features thereof; but what I claim is :-
-
(1.) The herein described means of making good damaged pipes, that is to say,
by the employment of clip or coupling chests or boxes made in two or more parts

page_text: or sections, said sections being connected together and provided with means, sub-
stantially as described, for making a tight connection between the pipes to be made
good and the said clip or coupling chests or boxes.
(2.) The appliances for making good damaged pipes, consisting of the parts set
forth with reference to and shown in the different figures of the drawings.
Dated this 29th day of April 1892.
