Improvements in Tin Lined Lead Pipes or Tubes.
I, ALBERT BARRACLOUGH, of High Street, Heckmondwike, in the County of York,
Plumber do hereby declare the nature of this invention to be as follows:-
This invention relates to tin lined pipes used for the purpose of preventing lead
poisoning and employed principally for domestic use.
In constructing a tin lined lead pipe according to my invention I use an ordinary
form of leaden pipe within which is inserted a tin pipe of less diameter but between
the lead and the tin pipes I introduce a liquid cement or composition which immediately
sets whereby the three parts or surfaces become fixed and this is accomplished
without any pressure within the tin tube or any external pressure or "drawing" or
"rolling" on the outer surface of the leaden tube which has hitherto been the
custom.
By the introduction of the intermediate cement or composition the tin pipe has no
contact with the leaden pipe consequently the poisonous ingredients from the lead
cannot get to the tin tube through which the water flows. In addition to leaden pipe
I intend using the same method in connection with iron, copper, brass or other pipes
as may be preferred.

I, ALBERT BARRACLOUGH, of High Street, Heckmondwike, in the County of York,
Plumber, 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 tin lined pipes used for the purpose of preventing lead
poisoning and employed principally for domestic use.
In constructing a tin lined lead pipe according to my invention I use an ordinary
fora of leaden pipe, within which is inserted a tin pipe of less diameter, but between
the lead and the tin pipes I introduce a liquid cement or composition which immediately
sets, whereby the three parts or surfaces become fixed.
In order that my invention may be clearly understood I make reference to the
accompanying sheet of drawings illustrative thereof, wherein Fig. 1 is sectional
elevation of my improvements.
a represents the outer leaden pipe or tube, 6 the inner tin pipe or tube, and c
liquid cement. introduced between the two pipes under pressure by means of a
force pump, or by gravitation assisted by exhausting the air from between the two
pipes.

page_text: In order to keep the inner tin pipe or tube concentric with the outer lead pipe,
I wrap spirally around the inner pipe, twine, asbestos, yarn, lead, brass, copper or
other wire, or I lay any of these or similar materials in parallel strands longitudinally
on the inner surface of the lead tube or the outer surface of the tin pipe or tube.
By the introduction of the intermediate cement or composition the tin pipe has
110 contact with the leaden pipe consequently the poisonous ingredients from the lead
cannot get to the tin tube through which the water flows.
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-
The combination of tin and lead pipes kept apart from each other by liquid
cement or composition in manner described herein and for purposes set forth.
