WILLIAM WILLIS Plumber and Sanitary Engineer 33
Dublin Road Belfast, Co. Antrim Ireland, do hereby declare the nature of this
invention to be as follows:-
My invention is an improved detachable joint or connection between lead pipe
and metal or earthenware pipe, and in order that my said invention may be properly
understood reference is made to the accompanying sheets of drawings wherein the
same figures of reference indicate the similar parts.
Figure 1 is lead waste or soil pipe which may be the discharge from water closet,
slop sink, bath, urinal or any fitting where there is a waste or discharge pipe
between lead pipe and iron or metal pipe or junction connection.
Figure 2 is loose metal or brass flange or collar, fitted behind the lead flange or
collar attached to the lead pipe.
Figure 3 is lead flange, which may either be cast on or soldered on lead pipe.
Figure 4 is indiarubber ring for packing the joint between the lead and metal or
iron, if I so desire, I may use red lead or other packing in screwing or bolting the
joint together.
Figure 5 is flange or collar cast on faucet of metal pipe or junction, but if I
so require, I may make the flange or collar loose fitting, over an earthenware pipe
or junction.
Figure 6 is iron or brass bolts and thumb screws for binding the joint together.
Figure 7 shows the joint made complete, with the different parts forming a com-
plete and perfectly gas or water tight and detachable joint between lead and metal
or earthenware.

COMPLETE SPECIFICATION.
Improved Detachable Joint between Lead and Iron or Earthenware
Pipe or Junction.
I, WILLIAM WILLIS of 33, Dublin Road, Belfast in the County of Antrim,
Ireland, Registered Plumber and Sanitary Engineer, 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 :-
I submit one sheet of drawings as part of, and reference for this Specification.
In Figure 1 A. is the lead pipe.
B. is a metal or brass flanged collar, with lugs for bolt holes, as shown, placed
behind the lead flange, collar or shoulder C. and may be attached to the lead
pipe A. if I so desire it.
C. is a lead flange, collar or shoulder, which may either be cast or soldered on
lead pipe A.

page_text: D. is an indiarubber disc-ring or washer for packing and rendering watertight the
joint between the lead pipe A. and the metal or iron junction A. If I so desire,
I may use red lead or other suitable packing when making up the joint.
E. is a flange or collar cast on faucet end of metal pipe or junction A'.
1 so require, I may make the flange or collar E loose fitting over an earthenware
pipe or junction.
But, if
F. are the iron or brass bolts & nuts, for binding the lead pipe A. to the metal
pipe or junction A¹.
In Figure 2 I propose to form and secure the junction of the lead and metal or
earthenware pipes, by forming a lip or reflex flange on and around the extremity of
the lead pipe A. as shown. I there place on, (and if I so desire I may secure to)
the lead pipe A. a metal or brass flanged collar B' with lugs formed thereon for
bolt holes. The junction E. on metal pipe A' is formed similarly to that in Fig. 1.
It will be seen on reference to the drawings that-in Fig. 1 by screwing up the
bolts and nuts F. the lead flanged collar or shoulder C. will be made to press
against and jamb the indiarubber disc-ring or washer D. and by so doing will cause
a displacement in the bulk of said washer which will press and act against the
flanged junction E. and the extremity of lead pipe A.
In Fig. 2 by screwing up the bolts and nuts F. the metal or brass flanged collar B₁
will be made to press on and around the lipor reflex flanged end of lead pipe A.
thereby causing a wedge and press on the lead pipe A. and the flanged junction E.
which then secures and maintains the junction of the lead and metal or earthenware
pipes substantially as described.
And, having now thus described and ascertained the nature and object of this
invention, I wish it to be distinctly understood, that I claim-
The number, arrangement and combination of parts specially referred to herein
and shown on the drawings attached hereto, forming an improved detachable joint
or connection between lead and metal or earthenware pipes.
Dated this 26th day of December 1894.
