PROVISIONAL SPECIFICATION.
Improvements in the Construction of Tubular Receivers or Pipes
for the Reception of Underground Telegraph Lines and the
like.
I JOHN AIRD of 37 Great George Street in the City of Westminster Contractor
do hereby declare the nature of this Invention to be as follows:-
My Invention has for its object to provide receivers or pipes for the reception of
underground telegraph lines or the like which receivers or pipes will be less liable to
become ruptured by subsidence of the soil in which they are laid, or otherwise get out
of order, or be injured, than are such receptacles, or pipes as ordinarily constructed
or arranged.
According to my Invention I employ earthenware piping or hollow portions in any
suitable lengths and I join them together by means of metal collars which encircle
the juxtaposed ends of the lengths & closely cover the joints-I prefer to use cast iron
joints for this purpose.

I, JOHN AIRD, of 37 Great George Street in the City of Westminster, Contractor
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 has for its object to provide receivers or pipes for the reception of
underground telegraph lines or the like, which receivers or pipes will be less liable
to become ruptured by subsidence of the soil in which they are laid, or otherwise get
out of order or be injured than are such receptacles or pipes as ordinarily constructed
or arranged.
According to my Invention I employ earthenware piping or hollow portions in any
suitable lengths and I join them together by means of metal collars which encircle the
juxta-posed ends of the lengths and closely cover the joints. I prefer to use cast iron
joints for this purpose. The accompanying drawing represents in longitudinal section
in Figure 1 and in transverse section in Figure 2 so much of a receiver or pipe
constructed according to my Invention as is necessary to shew how my Invention may
be performed. A are the lengths of earthenware piping or hollow portions joined
together by means of the metal collars B encircling the juxtaposed ends of the lengths
and closely covering the joints. Any suitable cement lead or other material may if
desired be used between the earthenware and the metal.
The Invention is applicable to purposes analogous to that mentioned for example it
may be used for the construction of receivers or pipes for the passage of water gas or
for drainage purposes.
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.
Receivers or pipes for underground telegraph lines or the like (as hereinbefore
indicated) the said receivers or pipes consisting of lengths of earthenware tubing or
hollow portions connected or covered at the joints by metal collars substantially as
hereinbefore described and illustrated by the accompanying drawings.
