COMPLETE SPECIFICATION.
Improvements in Joining Earthenware to Metal Soil Pipes.
I, FREDERICK RICHMOND of 53 Northcote Road Battersea Rise in the-
County of Surrey Sanitary Engineer, do hereby declare the nature of the said.
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 a method of and apparatus for joining earthenware pipes
to metal pipes and is more specially applicable to attaching the earthenware outlet
of water closets to the lead or other soil pipes in an efficient and expeditious
manner.
I will now fully describe my invention aided by the accompanying drawings in.
which
Figure. 1. is a perspective view of one method of constructing a connecting thimble
according to my invention.
Figure. 2. is a side elevation partly in section of a connecting thimble similar to
Figure. 1. but provided with a bend.
Figure. 3. is a perspective view of a connecting thimble having a straight lining-
for connecting to the lead or other soil pipe.
Figure. 4. is a side elevation partly in section of a connecting thimble similar to
Figure. 3. but provided with a bent lining.
Figure. 5. is a section of a modification of Figures 3 and 4 and
Figure 6 is a perspective view of a connecting thimble provided with lugs and
bolts and nuts for screwing up.
In all the figures like parts are denoted by similar letters of reference.
The connecting collar or thimble a is tapered or bevelled so as to form a key b
when the collar is cemented to the earthenware outlet c of the water closet trap..
The collar a is provided with three or more centering or adjusting screws d to ensure
the collar a being centrally secured to the earthenware outlet c.
In Figures 1 and 2 the collar a is provided with a tinned tail piece or end a
either straight or bent for soldering to the lead or other soil pipe e or for lead.
caulking where iron soil pipe is used.
In Figures 3, 4, 5 and 6 means are provided whereby great facility is afforded for

disconnecting at any time for cleansing or other purposes; it is effected by a
cap and lining 9, the cap is provided with lugs f¹ having holes f formed therein
to take an iron pin or
* tommy or for tapping with a mallet for screwing the
cap home.
In Figure 3 it is shown with a straight lining for connecting to the soil pipe e
by a wiped or plumbers joint and in Figure 4 it is shown with a bent lining g.
In the section shown at Figure 5 the collar or connecting thimble a is shewn
cemented to the earthenware water closet trap outlet c the screwed end a³ of the
collar a is provided with a ♥ shaped raised seating a³ which embeds itself into the
lead or other flange e' thus ensuring a perfectly sound gas tight joint.
This screwed end a² is turned down as shown at e² of size small enough to allow
the lead pipe or T piece e to pass over. A hard metal ring his then passed over the
lead pipe and the lead pipe flanged over the said ring hand the cap screwed home.
It will thus be seen that by the use of this method of connecting the water closet
outlet to the lead soil pipe it is connected up without the use of solder and
that a perfectly sound and imperishable gas and water tight connection is made, at
the same time it allows of the water closet being disconnected from the soil pipe at
any time for cleansing the outlet of the trap and soil pipe and refixing the same
as clean as new in a very few minutes and without calling in the aid of a plumber
or other skilled mechanic.
In the modification shown at Figure. 6. a similar result is obtained but instead of
using the screwed capf I employ an iron or other collar i provided with lugs and
I cast or otherwise form corresponding lugs or hooks a* on the connecting collar or
thimble a into which the flattened T shaped ends k¹ of the bolts k fit, it will be
readily seen without further description that on the nuts k³ being screwed home a
perfectly sound gas and water tight joint will be the result.
If desired the connecting collar or thimble may be corrugated, fluted, indented
or otherwise fashioned to ensure a perfectly sound cement key or joint.
My invention is also applicable to connecting up bath and other traps.
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 means or apparatus for readily connecting and disconnecting the water
closet or other earthenware outlet to the lead soil or other pipe substantially as
herein described and shown in the accompanying drawings.
Dated this 7th day of July 1894.
