I, EDWIN HUSSELBEE, of Hawbush Villas, Brettell Lane, near Stourbridge,
Staffordshire, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has reference chiefly to improvements in or connected with uniting
the ends of those cast iron pipes which are used for conveying steam or hot water
in heating apparatus, but it can also be applied to like pipes for other purposes.
An ordinary method of connecting together the ends of such pipes is by means of a
collar cast at each end of each pipe in a piece therewith, each of such collars having
two lugs or ears at opposite sides of the pipe through which the connecting bolts pass
for drawing the ends of the pipes together; rubber, asbestos or other jointing material
being used between them.
In laying a range of these pipes in which there are several bends and pipes on
different levels it is found, as is well known, that the holes in one pipe or bend will
come perhaps at right angles to those in the pipe with which it is required to joint,
hence special pipes and bends have to be made with their lugs either "right" or
"left" hand in order that they may match and joint together, which causes incon-
venience and delay and thus increases the cost of the work.
The object of this invention is to so construct the said pipes that the connecting
collar and lugs of any pipe can be adjusted to match any other pipe to which it
is required to be connected thus avoiding the necessity of casting special pipes.
For simplicity I will describe my invention as applied to one end only of a
cast iron pipe but it is to he understood that my invention can be similarly
applied to both ends thereof. I cast a loose ring or collar round the outside of
the pipe this ring or collar having two or more holes for the connecting bolts
and being by preference of the same shape as the collars and lugs above mentioned
as usually cast on the ends of the pipe. At or near the end of the pipe and
cast in a piece therewith is a fixed (preferably circular) collar large enough to
prevent the loose collar being removed from the pipe.

page_text: A pipe thus formed can be connected to another one in the usual manner by
bolts passing through the bolt holes in the loose collar and drawing the ends of the
pipes together and the loose collar can be turned round and adjusted on the pipe for
its bolt holes to match those in the pipe to which it is required to be connected.
I prefer to cast the loose collar or collars around the pipe at the same time as the
pipe itself is cast which can readily be done by making the collar pattern on the body
of the pipe pattern and moulding them both together and then laying a thin ringlike
core in the mould to separate the collar from the pipe.

Improvements in or Connected with Uniting the Ends of Cast Iron
Pipes.
1, EDWIN HUSSELBEE, of Hawbush Villas, Brettell Lane, near Stourbridge,
Staffordshire, 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 :-
This invention has reference chiefly to improvements in or connected with uniting
the ends of those cast iron pipes and connections which are used for conveying
steam or hot water in beating apparatus, but it can also be applied to like pipes for
other purposes.
An ordinary method of connecting together the ends of such pipes is by means of a
collar cast at each end of each pipe in a piece therewith, each of such collars having
two or more lugs or ears at opposite sides of the pipe through which the connecting
bolts pass for drawing the ends of the pipes together; rubber, asbestos or other
jointing material being used between them.
In laying a range of these pipes in which there are several bends or branches,
and pipes on different levels it is found, as is well known, that the bolt holes in one
pipe or bend will come perhaps at right angles to those in the pipe with which
it is required to joint, hence special pipes and bends or other connecting pipes have to
be made with their lugs either "right" or "left" hand in order that they may match
and joint together, which causes inconvenience and delay and thus increases the cost
of the work.
The object of this invention is to so construct the said pipes that the connecting
collar and lugs of any pipe can be adjusted to match any other pipe bend or connecting
piece to which it is required to be connected thus avoiding the necessity of casting
special pipes or bends etc.
For simplicity I will describe my invention as applied to one end only of a cast iron
pipe but it is to be understood that my invention can be similarly applied to both
ends or any of the branches thereof. I cast the pipe with a loose ring or collar round
the outside of the pipe this ring or collar having two or more lugs with holes for the
connecting bolts and being by preference of the same shape as the collars and lugs
above mentioned as usually cast on the ends of the pipe. At or near the end of the
pipe and cast in a piece therewith is a fixed (preferably circular) collar large enough
to prevent the loose collar being removed from the pipe.
On the accompanying drawing Fig. 1 represents in part section the ends of two
pipes connected together one of which is provided with a loose collar according to my
invention cast with that pipe; Fig. 2 is an end view of the same and Fig. 3 shews
the same parts disconnected; Fig. 4 is a separate view of the loose collar and
Figs. 5 and 6 shew how a bend or pipe may be cast with the loose collar according to
my invention for connecting the bend or pipe to another pipe.
The same letters of reference indicate the same parts in all the figures.

page_text: The ends of the two pipes which are required to be jointed together are marked
respectively a and b. The end a is an ordinary socket furnished with lugs a' a' and
bolt holes c. The end of the pipe b is a spigot adapted to fit in the socket end of the
pipe a and provided with a collar 6 cast integral with the pipe b. d is the loose
collar with which the pipe b is cast this collar having lugs and bolt holes to match the
lugs a a and bolt holes c. The pipe 6 is connected to the pipe a in the usual
manner by bolts e passing through the bolt holes c in the lugs aa and through the
bolt holes in the loose collar d (see Fig. 1) which draw the ends of the pipes a and b
together, the recess d³ in the loose collar d engaging with the collar 6. By the
collar d being loose it can be turned round and adjusted on the pipe 6 for its bolt holes
to match those in the pipe to which it is required to be connected, and the pipe b can
also be turned round in the collar as may be required. The rubber, asbestos or other
jointing material is marked f.
The loose collar d may be cast around the pipe 6 at the same time as the pipe
itself is cast which can readily be done by making the collar pattern on the body of
the pipe pattern and moulding it and the pipe together and then laying a thin ring-
like core in the mould to separate the collar from the pipe; this ring like core being
threaded on to the pipe core and supported therefrom by chaplets or by other well
known means.
Or instead of casting the loose collar and the pipe together at the same time as
above described the loose collar may be cast first in a separate mould and this is the
method I prefer and which as applied to one end of a bend is illustrated by
Figs. 4, 5 and 6. After the loose collar is cast it is lined with suitable core
material h, as shewn by Fig. 4, and threaded on to the bend core g and placed with
the bend core in the half mould i for the bend as shewn in Fig. 5; the other half
mould is then placed on the top and the bend cast in the usual way it being separated
from the loose collar d as shewn by Fig. 6 by the core lining which also prevents
the bend b being chilled by the collar d. The core lining is then removed from
the collar and the bend is ready for use. The face of the collar d is by preference
recessed at as shewn so as to fit loosely around the collar of the pipe or
bend to prevent any unnecessary side play of the collar d on the pipe and
allow of a thickness of core material against the collar 6 when the pipe or bend
is being cast.
It is to be understood that by the word "pipe" I include all kinds of shapes
of cast iron or other cast metal pipes whether they are straight lengths, tees,
crosses, bends or other connecting pipes.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The combination with a cast metal pipe having a fixed end collar or
collars cast integral therewith, of a loose collar or loose collars through which the
pipe passes and with which the pipe is cast so as to be non-removable therefrom,
the said loose collar or loose collars being constructed substantially as, and for the
purposes, described.
2nd. The combination with the pipe b cast integral with the end collar 6, of a
loose collar or loose collars d, with which the pipe b is cast so as to be
non-removable therefrom, for the purposes, and substantially as described.
