PROVEMENTS IN THE CONSTRUCTION AND MODES OF CONNECTING PIPES OR

COMPLETE SPECIFICATION filed by the said Victor Delperdange āt
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 27th April 1868, pursuant to the 9th Section:
..of the Patent Law Amendment Act, 1852.
TO. ALL TO WHOM THESE PRESENTS SHALL COME, I, VICTOR
DELPERDANGE, Civil Engineer, of the City of Brussels, in the Kingdom
of Belgium, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN THE CONSTRUCTION AND MODES OF CONNECTING PIPES OR TUBES OF METAL OR
OTHER MATERIAL," and have petitioned Her Majesty to grant unto
me, my executors, administrators, and assigns, Her Royal Letters Patent
[Price 8d.]

page_text: for the same, and have made solemn declaration that I am the true
and first Inventor thereof.
NOW KNOW YE, that I, the said Victor Delperdange, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed, in and by the following
statement, reference being had to the Drawings hereunto annexed, and
to the figures and letters marked thereon, that is to say:-
.
My said Invention consists in certain improvements in the con-
struction of pipes or tubes of metal or other material, and in the
combination and arrangement of mechanism whereby such pipes or
tubes are connected together with great simplicity and efficiency.
The nature of my said Invention will be more clearly understood by
reference to the annexed Drawings throughout the following description.
One portion of my improvements consists in constructing the end
of each tube or pipe A, Figures 1, 2, and 3, with an enlargement as
shewn at B in the same Figures, in order to prevent the breaking or
cracking of the tubes or pipes by means of concussions or blows to
which they may be subjected. This mode of construction admits of a
considerable decrease being made in the thickness of the body of the
pipes or tubes.
The form or outline of the Terminal ring or flange instead of being
single may be made double, as shewn at C, Figure 3, or triple or quad-
ruple, or the top of the ring or flange may be flattened as at C, Figure 4,
so as to enlarge the surface of the joint. These flanges or rims may also
be made hollow or sunken instead of projecting as shewn at C³, Figure 5.
A small plate or cover is used for the joints, the same being made
with flanges, and embossed or stamped as shewn at Figures 6 and 7.
A ring of caoutchouc or other elastic substance is placed around each
joint, such rings being made with ribs on one or other or on both of
the surfaces in order to increase their elasticity and to increase the
number of points of contact, see Figure S. Each joint is surrounded
by a collar which is entirely made of a strip of rolled iron including
the ears, as shewn in outline at D, Figure 3.
The collar can be fluted as at E, Figure 25, if required to extend

page_text: Liuted.
In order to direct the tightening strain towards the centre
the claws of the collar may be lengthened so as to act as a buttress,
as shewn at E, Figure 25, or the ends of the claws may be doubled
inwards so as to form a flange to one claw G, Figures 9 and 10, or
to both as at H, Figure 11.
A simple wedge laid longitudinally may also be driven between
the two claws, as at I, Figure 12, or the wedge may be used trans-
versely. Two wedges superposed. may also be used, both being free,
as at K, Figure 13, or one fixed and the other moveable, as at L, M,
Figure 14. A. wedge and ring or hoop arranged as shewn at N, n,
Figures 15 and 16, may also be used, and the use of a bolt (as shewn
in the Figures) avoided. The stirrup or tie O with one or more
keys P may also be used singly for tightening, or with a bolt, as shewn
in Figures 17 and 18. The tightening of the collar may also be con-
pleted by a safety apparatus composed of a stirrup or tie Q, Figures 19,
20, and 21, through which the bolt R passes, and the place of which
it supplies in case of breakage. The collar being sufficiently tightened,
at key fixes the tie or stirrup by the side and against the head of
the bolt. Any similar or analogous means may also be used, for
instance, a counter plate T closed by two screw bolts t, the ears of
the tie or stirrup being screw cut, as shewn in Figure 21, or if they
are not provided with a screw thread the screw bolts may be replaced
by keys. The tightening screw bolt may be replaced by a bolt fastened
by one
or two keys, or two bolts placed one over the other, one
being a screw bolt, and the other a keyed bolt are applicable,
or the two bolts may be of the same kind. In order to strengthen
the connection or joint, ears or lugs, either fixed or moveable (sce
U, Figures 22, 23, and 24) united by two bolts, Figure 24, or by
several of the kind shewn at Figures 22 and 23, may be added to
the cars of the collar. The screw bolts and the key bolts W may
be substituted for each other. These different descriptions of collars
may be made of steel by which their strength and duration may be
increased. By means of the same arrangements tubes or pipes having
no projecting parts as at X, Figure 25, may be connected. The collar
in such cases must be constructed of flat iron or steel, that is to say,
with flanges, or the latter may be placed on the outer-side of-the
collar, the small plate or cover joint never failing to adapt itself exactly
to the form of the collar, and having on each side a flange giving it
:

page_text: the required rigidity. These modifications are specially applicable to
the connecting of copper or drawn iron pipes or tubes on the end
of which small rings or flanges either sunken or raised may be formed.
The collar shewn in Figures 1, 3, 9, to 24, usually employed in
the various arrangements above described, instead of having ears
tightened by bolts or otherwise may have hooks with keys, as at Y
Figures 26, 27, and 28, or by hinges Z, Figure 28.
The various kinds of pipes and tubes, collars, the plates called cover
joints, and the rings of caoutchouc or other elastic material above
described can be combined and used one with another according to
the object it may be required to carry out.
1 will now refer to the annexed Drawings seriatim.

joint, and caoutchouc ring; Figure 2 is a transverse section of one

screw nut and two safety bolts with keys, and Figure 23 is a side view,
of the same arrangement; Figure 24 is a front view of a collar with

page_text: lugs, and Two bolts and screw nuts for tightening; Figure 25 is a
longitudinal section of two pipes or tubes without any projecting parts
connected by a fluted collar with ribs on the outer side; Figure 26 is

Having thus declared and ascertained the nature of my said Inven-
tion, and the manner in which it is to be performed, I would observe
in conclusion that what I consider novel and original, and therofore
claim are, the methods of constructing pipes or tubes, and the com-
bination and arrangement of parts and mechanism for connecting the
same, Substantially as herein-before described and set forth, or any mero
modifications thereof.
In witness whereof, I, the said Victor Delperdange, have hereunto
set my hand and seal, this Twenty-fourth day of April, in the
year of our Lord One thousand eight hundred and sixty-eight.
