PROVISIONAL SPECIFICATION.
A Method of Lining Spigot and Socket, Flange, or Snug Pipes with.
Enamel, Glass, Composition, or other Material.
I, FRED HERBERT, Moseley House, Birtley, near Newcastle on Tyne, County
of Durham, Engineer, and Iron Works Manager, do hereby declare the nature
of this invention to be as follows:-
Assuming the pipes to have been moulded and cast in the ordinary manner, I
purpose to extract them from the moulds whilst hot, and after having (by mechanical
or other means) cleaned the sand and other impurities from the interior of the
pipes, they would be caused to revolve, either by rolling them upon a gantry, upon.
their external diameters, or they may be caused to revolve upon or around their
longitudinal axis, by any suitable mechanical contrivance and whilst the pipes are
situate in or upon the said gantry or machine, a proper quantity of (liquid or solid)
enamel glaze, composition, glass or other material suitable for lining, is to be
injected or applied to the interior of the pipes the pipes being revolved at any
suitable speed, until the lining is properly melted, distributed, baked dried, fixed
be pre-.
or set, upon the interior surfaces of the pipes. The pocket portion may
vented from being lined by a core plug, or other arrangement, or instead of the
pipes being taken direct from the moulds, and the lining applied before the casting
had time to cool, as before described, it may be convenient to have the pipes
reheated to any required temperature, and this reheating may be accomplished in
a reheating furnace, by gas or other heating medium, or the pipes may be heated
or reheated by passing hot air, gas or flame, through, in, or upon them, whilst they
are in or upon the gantry or machine used for revolving them.
In the case of a pipe (or pipes) made as per method invented by me and described.
under Patent No. 65288, the material used for lining might be injected or applied
to the interior of the pipe whilst it was in the mould in which it had been cast, and
in that case the pipe and mould would be revolved together at any suitable speed,.
by the same or any other mechanical process.

COMPLETE SPECIFICATION.
A Method of Lining Spigot and Socket, Flange, or Snug Pipes with
Enamel, Glass, Composition, or other Material.
FRED HERBERT, Moseley House, Birtley near Newcastle on Tyne, Iron Works
Manager, 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 :-
For the purpose of more clearly explaining the nature of my invention I have
annexed a sheet of drawings, Fig. 1 on which shows a longitudinal section through
an arrangement of furnace or furnaces, whilst Fig. 2 is a sectional plan and Fig. 3 is
a cross sectional elevation of the same.
The pipes after having the core extracted (by any suitable means) either before
or after cooling, are placed upon a gantry A, and are rolled through the door B
into the soaking or reheating furnace C. When the proper heat is reached in
furnace C, the pipes are passed through the door D and rolled or placed upon the
rollers E. The pipe now rests upon these rollers E as shown, and whilst in this
position a perforated tube For its equivalent is passed through the interior of the

page_text: pipe. This tube F contains a mixture of enamel, glaze, glass, or composition and
may be carried in bearings or run upon rollers. The rollers E together with the
pipe are now caused to revolve either by mechanical or any other suitable means,
and at the same time the V piece or tube F containing the enamel or lining mixture,
is tilted or may be caused to revolve either in the same or opposite direction to the
pipe, the result being that the enamel glaze or composition is evenly distributed in
or upon the interior surfaces of the pipe, the sockets may also be covered internally
if so required.
The tube or V piece is now withdrawn and the pipes are rolled or passed into the
furnace H. The function of this furnace, is to melt, fix, fuze, or glaze, the enamel,
glaze, glass, or composition, upon the interior surfaces of the pipes. When this
is done the operation is complete.
The flues from the furnace C may be carried on into the furnace H, thus making
one continuous furnace, or each portion of the furnace or furnaces may have its own
fire as shown on drawing. The pipes may be rolled or carried through the furnace
or furnaces by means of an endless chain passing through the furnace, or by other
mechanical means, or the furnace may be inclined so that the pipes will roll by
gravitation, through the furnace or furnaces. It is evident that in the case of
pipes cast in a revolving mould as per method described in my Specification No. 6528
dated Jan. 16th the material used for lining, could be applied to the interior of
the pipes, immediately after casting, and before the pipe was removed from the
revolving mould and in that case the mould and the pipe would be revolved
together.
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
1st. The method of lining spigot & socket, flange or snug pipes with enamel,
glaze, glass, or composition as herein described.
2nd. The method of revolving the pipes upon fixed bearings or on friction or
other rollers, together with the distribution of the enamel, glaze, glass, or compo-
sition in or upon the interior surfaces of a pipe or pipes, by means of a tube,
V piece, or other equivalent, as particularly herein described.
3rd. The combination of furnace or furnaces, together with the arrangement for
revolving the pipes and the distribution of lining material by a tube (or any
equivalent) being passed through the interior of the pipe as herein fully described.
Dated this 11th day of September 1893.
FRED HERBERT.
