PROVISIONAL SPECIFICATION.
Improvements in or relating to Waste and other Drain Pipes
and the like.
I, RICHARD WHICHELLO, of 167, Park Road, Newcastle-on-Tyne, in the County
of Northumberland, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to waste and other drain pipes channels and the like,
and has for an object to construct them with as smooth a bore as possible in
order to prevent any solid matters from adhering to their inner surfaces.
According to this invention the pipes are formed of a glass tube with an outer
coating or casing of cement or like material. The glass tube may first be cast
in the desired shape, with or without ears, feathers, serrations, cross cuts or
other means for causing the cement to adhere to its outer surface. The outer
coating may be applied in some convenient manner, such as, for instance; by
placing the glass tube as a mandrel in a mould or jig and casting the cement
round it. Or the pipes may be closed at one or both ends and dipped and
revolved in the cement, the number of dips or revolutions depending on the
thickness of cement required.
The glass tubes may be cast in any shape section or size, either straight or
bent, and are preferably provided with means for jointing, such as are commonly
used in earthenware drain pipes or in metal down comers, the joints being
made with cement.
"
In places where open drains are preferred, the glass tube may be replaced
by a glass channel of preferably semicircular cross-section, its convex face being
coated with cement.

Improvements in or relating to Waste and other Drain Pipes
and the like.
I, RICHARD WHICHELLO, of 167, Park Road, Newcastle-on-Tyne, in the County
of Northumberland, Clerk of Works, 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 relates to waste and other drain pipes channels and the like,

page_text: and has for an object to construct them with as smooth a bore as possible in
order to prevent any solid matters from adhering to their inner surfaces.
According to this invention the pipes are formed of a glass tube with an outer
coating or casing of cement or like material. The glass tube may first be cast
in the desired shape, with or without ears, feathers, serrations, cross cuts or
other means for causing the cement to adhere to its outer surface. The outer
coating may be applied in some convenient manner, such as, for instance, by
placing the glass tube as a mandrel in a mould or jig and casting the cement
round it. Or the pipes may be closed at one or both ends and dipped and
revolved in the cement, the number of dips or revolutions depending on the
thickness of cement required.
The glass tubes may be cast in any shape section or size, either straight
or bent, they may be made in two parts divided longitudinally and are preferably
provided with means for jointing, such as are commonly used in earthenware
drain pipes or in metal "down comers," the joints being made with cement.
In places where open drains are preferred, the glass tube may be replaced by
a glass channel of preferably semicircular cross-section, its convex face being
coated with cement.
In the accompanying drawings:-
Figures 1, 2 and 3 are cross sections of various pipes all according to this
invention, and
Figure 4 is a perspective view of an open pipe also according to this invention.
Like letters indicate like parts throughout the drawings.
A is the inner tube or pipe of glass, and B is the coating of cement or like
material surrounding it.
In Figures 1 and 2 the inner tube A is of circular cross section, and is sur-
rounded, in Figure 1, by a circular coating of cement, and in Figure 2 by a
coating which is square in cross section.
In the pipe illustrated in Figure 3 both the inner tube and coating are of
square shape in cross section.
Figure 4 shows an open pipe according to this invention, the inner half-pipe A
being semicircular in cross section, and having ribs A¹ upon its convex surface,
which help to retain the outer coating B of cement.
It is to be understood that the pipes or half pipes illustrated in the accompany-
ing drawings are merely given by way of example, and that pipes of any shape
or size may be used without departing from the spirit of this invention.
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:-
:-
1. A cement or similarly coated glass pipe for drainage purposes.
2. In a drain pipe or the like the combination substantially as described with
an inner tube or half tube of glass of an outer coating of cement or similar
material.

3. A drainage pipe or half pipe substantially as described and illustrated in
Figure 1 or Figure 2 or Figure 3 or Figure 4 of the accompanying drawings.
Dated this 28th day of August 1899.
