PROVISIONAL SPECIFICATION.
Improvements in Earthen-ware Pipes.
I, REGINALD FREDERICK YORKE, of the Red House, Barbam, near Canterbury
in the County of Kent, Electrical Engineer do hereby declare the nature of my
invention to be as follows:-
My invention relates to pipes of earthenware, such as are generally used as
conduits for water and other liquids, or for encasing electric conductors or other
purposes, and has for its object the carrying out of certain improvements in the
manufacture of the said pipes, by which they are made stronger.
It has been found when earthenware pipes have been used for the conduction of
water under pressure, for the purpose, for instance, of supplying turbines, that such
pipes are exceedingly liable to fracture or breakage, so much so, that it is
customary to use metallic pipes for this purpose.
This latter expedient however is very expensive, in fact, in actual practice the
metal pipes cost about 4 times that of earthenware pipes.
My invention is designed to overcome this difficulty, and consists in winding
around the ordinary earthenware pipes, strips of metal, either in the form of flat
bands or wire.
These strips may be wound upon the pipes spirally, that is, commencing at one
end of the pipe and finishing at the other end, or the strengthening may be effected
by independent bands or rings placed at intervals along its length.
When the bands or wire-armouring are arranged upon the pipe, I dip the pipe in,
or coat it on its exterior with, Portland or other cement, so as to thoroughly form a
substantial support between the armouring and the pipe, in order to make the
armiouring take up the tensile strain, due to internal or external pressure, and thus
strengthen the material of which the pipe is made.
The pipe may be coated with tar or other suitable substance if desired.

Improvements in Earthen-ware Pipes.
I, REGINALD FREDERICK YORKE of the Red House, Barham, near Canterbury,
in the County of Kent, Electrical Engineer, do hereby declare the nature of my
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 pipes of earthenware, such as are generally used as

The pipe may be coated with tar or other suitable substance if desired.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The combination with an earthenware pipe of a strengthening armour or
covering of metal wire or strips, wound spirally upon the pipe from end to end at
any desired closeness of pitch, substantially as for the purposes described.
2nd. The combination with an earthenware pipe of a strengthening armour or
covering, consisting of separate bands of metal wire or strips, wound upon the
pipe, substantially as and for the purposes described.
3rd. An earthenware pipe strengthened by an armouring or covering of metal
wire or strips, wound upon the pipe in a continuous spiral or in separate bands, and
dipped into or coated with Portland or other cement, covering and filling the
interstices of the said metal armour or bands, substantially as and for the purposes
described.
