Improvements in the Manufacture of Rain Water or similar Pipes.
I, JOHN ROBINSON CROSTHWAITE of the Union Foundry, South Stockton-on-
Tees in the County of York, Ironfounder, do hereby declare the nature of this
invention to be as follows:-
My invention relates to the manufacture of pipes, such as rain water, soil or
other pipes which are furnished with cars to fix them in position as for instance to
the wall of a building.
Pipes employed for these purposes as at present constructed usually have the
cars cast in one piece with the pipe and are consequently liable to be rendered
useless by an ear breaking off in transit or in fixing and in taking a pipe down.
A further defect in the present usual mode of constructing pipes of this class is
that the cars extend from the pipe approximately in a line so near the outside of
the pipe that when the pipe is fixed in position, say to the wall of a building, it is
so close as to run the water against the wall in case of a stoppage or broken
pipe and the space behind the pipe is too small to allow of proper access thereto
for the purpose of painting the back part of it.
The object of my invention is to effect improvements in these respects by
providing specially constructed cars of a non-brittle material which I unite to the
pipe in the process of casting in such a manner that the cars are as strong as the
pipe itself and can be varied in form so as to provide any required distance between
the pipe and the wall when fixed in position.
In carrying my invention into effect I stamp the cars from a tough or non brittle
material such as iron or steel and of such shape as will afford strength and rigidity
and will enable the pipe to be set off at any required distance from the wall or other
surface to which it is attached.
The ears may be varied in design without departing from the nature of my
invention and are stamped in one piece in the form of a bracket which is secured to
the body of the pipe in the following manner :-the centre part of the bracket is
curved to follow the outside circumference of the socket of the pipe and is also
corrugated at the same part transversely to the length of the pipe. When the pipe
is cast the bracket is placed in the mould so that the metal of the pipe fills up the
corrugation of the bracket and overlaps the edges thereof, which are thus interlocked
and the ears which are the terminals of the bracket are thus secured to the pipe
in their intended positions. In stamping the ears I prefer to increase their strength
and rigidity by turning over the edges say to a quarter of the circle, which edges
form the bearing surface against the wall added to which holes for the securing
nails are punched through the ears with their edges turned in towards the same
direction to give strength and surface for the nails to bear upon.
By uniting the ears together in the form of a bracket to be secured to the pipe
in the above described manner the shape of the bracket is capable of such variation
as will set the pipe at any required distance from the wall or other surface to which
it is attached.

Improvements in the Manufacture of Rain Water or similar Pipes.
I, JOHN ROBINSON CROSTHWAITE of the Union Foundry, South Stockton-on-
Tees in the County of York, Ironfounder, 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 the manufacture of pipes, such as rain water soil or other
pipes which are furnished with ears to fix them in position, as for instance to the
wall of a building.
Pipes employed for these purposes as at present constructed have the ears cast
in one piece with the pipe and are consequently liable to be rendered useless by an
car breaking off in transit or in fixing and in taking a pipe down. A further defect
in the present mode of constructing pipes of this class is that the ears extend from
the pipe approximately in a line so near the outside of the pipe that when the pipe
is fixed in position say to the wall of a building, it is so close as to run the water
against the wall in case of a stoppage or broken pipe and the space behind the
pipe is too small to allow of proper access thereto for the purpose of painting the
back part of it.
The object of my invention is to effect improvements in these respects by providing
specially constructed cars of a non brittle material which I unite to the Pipe in the
process of casting in such a manner that the ears are as strong as the pipe itself
and can be varied in form so as to provide for any required distance between the
pipe and the wall when fixed in position.
And in order that my invention may be fully understood and readily carried into
effect I will now proceed to describe the same with reference to the accompanying
drawings, in which
Figure 1 illustrates in sectional view a rain water or other similar pipe con-
structed according to my invention and fixed in position against a wall.
Figure 2 is a corresponding sectional view in plan,
Figure 3 is a corresponding back view of the cars and pipe combined together
and
Figure 4 illustrates the ears in detail apart from the pipe.
of
a is the socket of the pipe to which the ears are attached in the process of
casting which ears I stamp from a tough or non brittle material such as sheet iron
or steel and of such shape, as will combine strength with rigidity and will enable
the pipe to be set off at any required distance from the wall or other surface to
which it is attached by varying the shape or pattern of the ears. The ears
which a convenient form for the purposes of my invention is shown in the drawing
may be varied in design without departing from the nature of my invention and are
stamped in couplets in the form of a bracket which is secured to the body of the
pipe in the following manner :-the central part 61 of the bracket is curved to
follow the outside circumference of the socket of the pipe (it will be observed that
a very slight curvature is sufficient for this) the part is also corrugated which
corrugations take a transverse direction to the length of the pipe as shown in the
figures. In casting the pipe the bracket is placed in the mould so that the metal
of the pipe fills up the corrugations of the bracket and forms the tongues c which
overlap the edges thereof and thus interlock the part of the bracket from which
the ears extend as terminals thereof. The ears are thus secured to the socket of
the pipe in their intended positions. In stamping the ears 6 I prefer to increase
their strength and rigidity by turning down the edges 62 thereof say to a quarter
of the circle, which edges form the bearing surface against the wall, added to which
holes d for the securing rails are punched through the ears with their edges also
turned in towards the same direction to give strength and surface for the nails to
hear upon.

page_text: By constructing the ears in a separate piece in the form of a bracket to be
secured to the pipe in the above described manner the pipe can be furnished with
ears of any shape or pattern required to set the pipe at any desired distance from
the wall or other surface to which it is attached.
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 :-
Firstly-The use and manufacture of rain water, soil or the like pipes in which
ears stamped or formed in steel or wrot iron or other equivalent thereof are united
to the socket or body of the pipe substantially in the manner and for the purpose
as hereinbefore described and illustrated by way of example in the accompanying
drawings.
Secondly: The particular construction or shape of the ears stamped or moulded
in wrot iron or the like non-brittle material to be united to and form part of rain
water or other pipes in the manner and for the purposes as hereinbefore described
and illustrated by way of example in the accompanying drawings.
:-
Thirdly The particular mode of securing the ears 6 to the rain water or other
similar pipe a, by means of the curved and corrugated part interlocked by the
overlaps c substantially as described and illustrated in the drawings.
