PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Rain Water or similar Pipes.
I, JOHN ROBINSON CROSTHWAITE, of The Union Foundry, Thornaby-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, and constitutes an
improvement upon the invention described and illustrated in my Specification
No. 16,820 of 1890..
The object of this invention is to effect an improvement in the ears attached to
the pipes by which I combine in them the requisite strength and durability with a
certain pliability which renders them more serviceable in some cases than when
made rigid by being stamped in one piece in the form of a bracket.
My invention consists as follows:-A bar of iron with each end coiled round to
form an car with a hole in it is curved at its centre part to follow the outside
circumference of the socket of the pipe. When the pipe is cast the bar of iron is
placed in the mould so that the metal of the pipe overlaps the edges thereof and
the iron bar is secured thereto in the form of a bracket, the ears of which can be
bent or curved more or less as required to set the pipe away from or close to the
wall or structure to which it is secured.
Dated this 30th day of November 1892.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Rain Water or similar Pipes.
1, JOHN ROBINSON CROSTHWAITE, of The Union Foundry, Thornaby-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 and constitutes an
improvement upon the invention described and illustrated in the Specification of
the Letters Patent granted to me and bearing date the 22nd October 1890 and
numbered 16,820.
The object of this invention is to effect an improvement in the ears and their
mode of attachment to the pipes by which I combine in them the requisite strength
and durability with a certain pliability which renders them more serviceable in
some cases than when made rigid by being stamped in one piece in the form of a
sheet iron bracket.
My invention which I will proceed to explain by aid of the accompanying
drawings consists as follows:-A bar of iron (which material is to be taken as the
representative of any suitable material such as steel or copper) with each end coiled
round to form an ear with a hole in it, or brought round in the form of an open
link which is curved at its central or intermediate part to conform to the outer
circumference or surface of the socket of the pipe into the metal of which it is
embedded more or less when the pipe is cast.

page_text: To the drawing,
Figure 1 illustrates in section, a view of a rain water or other similar pipe
constructed according to my invention and fixed in position against a flat wall..
Figure 2 is a back view of the ears and pipe combined together, that is with the
ears formed by coiling round the ends of a single bar.
Figure 3 is a similar back view of the ears and pipe combined together
corresponding to the sectional view in Figure 1, that is with the ears taking the
form of terminals of an ordinary link.
a is the socket of the pipe to which the ears are attached in the process of
casting, which ears I form by using a single bar of iron with its ends coiled round
as shown in Figure 2, or by using a double bar of iron in the form of a link as
shown in Figure 3.
The essential feature of these forms of brackets consists in the convenient and
serviceable manner in which they combine with a sufficient strength and durability,
a certain pliability by which they accommodate themselves to the configuration or
irregularities of the surface of a wall or are otherwise adjustable to provide any
required distance between the pipe and wall to which it is fixed, the iron bar or
bars of which the bracket is formed being easily bent more or less for this purpose
and the precise form, figure or outline of the iron bar in the form in which it is
used as a bracket is not in itself material so long as the foregoing conditions are
complied with.
Having now particularly described and ascertained the nature of
said inven-
my
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The particular construction of ears formed by coiling or otherwise bending or
configurating a tough, durable and pliable material, such as a wrot iron bar, the
said ears being attached to the pipes in the process of casting, as hereinbefore
described with reference to the accompanying drawing.
