Improvements in Joints or Unions for Pipes and the like.
I, WILLIAM SHOOSMITH, of 15 Ivory Place, Brighton, in the County of
Sussex, Drainage Inspector, do hereby declare the nature of this invention to
be as follows:-
My invention relates to joints or unions for pipes and the like, and is especially
applicable to the formation of sound gas-tight joints or connections between closet
basins and soil pipes, lavatory and urinal basins and their waste pipes, and stone-
ware, lead, and other traps or syphons and their corresponding pipes and similar
descriptions of joints or connections.
By means of my improved joint the operation of connecting two lengths of pipe
is greatly facilitated and, in the case of closet and other traps, or wherever else it
is desirable to adjust a pipe in a particular position relatively to a device of this
description or otherwise, the trouble and risk of damage entailed by the necessity
which frequently arises, where ordinary joints are employed, of cutting the said
pipes is obviated.
According to my said invention I provide a telescopic portion or length of pipe
formed of lead or other suitable metal or material. One of the parts forming this
telescopic length has at one end a suitable socket by means of which it can be secured
in manner hereinafter appearing or in any other suitable way to the earthenware
or lead arm of the trap or end of the pipe with which it is desired to form a
connection. This part is of such an external diameter as to form a nice fit inside
the pipe with which connection is to be made and also to pass within the other
length of pipe going to form the telescopic length. This latter length of pipe is
of such size as to pass within the socket of the pipe with which connection is to be
made (if that pipe is made of earthenware or the like and is socketted) and it may
be provided at its extremity with an outwardly projecting flange adapted to rest
upon the base of the socket of the adjacent pipe and with which connection may
be made by means of a cement or other joint. Or in the case of the telescopic
length being connected to a metal pipe a wiped metal joint may be employed.
It will be seen that the telescopic portion or length of pipe provides for a
cousiderable range of play or adjustment, when effecting the union between the
two parts it is desired to connect, by simply sliding or moving the one telescoping
part within the other so as to vary the length of the coupling. This, besides being
useful for the purposes hereinbefore mentioned, is advantageous in numerous ways
and especially it is of great utility in the fixing of the pedestal closets now in
vogue, which otherwise is a very difficult operation. A gas-tight joint can
be made between the said telescopic lengths by means of hemp and white or red
lead, or otherwise, and for the purpose of facilitating that operation I may form
the mouth of the outer telescopic length of pipe slightly flaring or bell-mouthed.
To ensure gas-tight joints and to retain the parts in position when adjusted, as
also to facilitate the prior adjustment thereof, I may provide suitable clamps or
straps each of which is preferably made in two parts adapted to be secured
together when in position by screws or bolts. One of these clamps or straps I
affix by means of the said screws or bolts to the socket portion of the inner
telescopic length of pipe, one or more indiarubber segments or rings or other

page_text: washers being first interposed, and another of these clamps or straps is affixed in a
like manner to the outer telescopic length of pipe just below the above mentioned
flaring or bell-mouthed extremity thereof. To admit of adjustment and likewise to
secure the parts together, I may form upon the above mentioned clamps or straps
suitable lugs or projections and 1 may pass adjusting screws through holes provided
in the lugs or projections upon one strap and screw them into correspondingly
screw-threaded holes provided in those upon the other, or I may employ bolts and
nuts for the like purpose.

Improvements in Joints or Unions for Pipes and the like.
I, WILLIAM SHOOSMITH, of 15 Ivory Place, Brighton, in the County of
Sussex, Drainage Inspector, 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 relates to joints or unions for pipes and the like, and is especially
applicable to the formation of sound gas-tight joints or connections between closet
and other traps and soil pipes and the like, lavatory and urinal basins and their
waste pipes, afd stoneware, lead, and other traps or syphons and their corre-
sponding pipes and similar descriptions of joints or connections.
By means of my improved joint the operation of connecting two lengths of pipe
is greatly facilitated and, in the case of closet and other traps and the like, or
wherever else it is desirable to adjust a pipe in a particular position relatively to
a device of this description or otherwise, the trouble and risk of damage entailed
by the necessity which frequently arises, where ordinary joints are employed, of
cutting the said pipes is obviated. I am thus enabled to effect a saving of time,
labour and material.
In the accompanying drawing:
Figure 1 is a vertical central section showing an application of my said
invention to a stoneware trap and pipe.
Figures 2 and 3 are similar views to Figure 1 shewing modifications hereinafter
described.
Like letters indicate corresponding parts throughout the drawing.
A indicates the trap aud B the soil or other pipe to be connected thereto.
According to my said invention I provide a telescopic portion or length of
pipe a formed of lead, stoneware or other suitable material. One of the parts
forming this telescopic length has at one end a suitable socket a¹ for attachment to
the outgo from the trap A by means of a clamp 6 with or without one or more india-
rubber insertions and secured or tightened by a bolt and nut or threaded lug as shown
at c, (Figure 2), red lead or other suitable jointing material being preferably used
between the socket and the trap to ensure a tight joint. The said telescopic length a
is of such an external diameter as to form a nice fit inside another length of lead or
other piped which latter is connected to the stoneware or other pipe B as indicated
The length of pipe d is formed slightly flaring or bell-mouthed, and when
the parts are adjusted in position a tight joint is formed between the pipes a and d
by a red lead or other joint as indicated at f. g is another clamp similar to the
one b secured upon the tube d and held in place by a bolt and nut or screw not
shown in the drawing in a similar mauner to the clamp b. h, h are bolts or screws
at e.

page_text: passing through the clamps 6 and g or lugs or projections thereon and thus serving
to admit of the prior adjustment of the parts and also to subsequently secure the
said parts together.
In Figure 1 the length of pipe d is secured to an earthenware or stoneware
pipe B, by a cement joint e, as already mentioned, whilst in the arrangement shown
in Figure 2 the said pipe d is connected to a lead pipe B by an ordinary wiped or
plumber's joint also marked e.
In the former case to render the joint e more secure I sometimes provide the
tube d at its extremity with an outwardly projecting flange d' adapted to rest
upon the base of the socket of the adjacent pipe B.
Figure 3 illustrates an arrangement wherein the telescopic length of tube or
pipe is formed by an extension a upon the trap and constitutes the connection
between the outgo A from the said trap and a soil pipe B. In this case the said
extension a is arranged to form a nice fit and telescope into, a branch B' upon the
pipe B as indicated in dotted lines.
It will be seen that the telescopic portion or length of pipe provides for a
considerable range of play or adjustment, when effecting the union between the
two parts it is desired to connect, by simply sliding or moving the one telescoping
part within the other so as to vary the length of the coupling. This, besides
being useful for the purposes herein before mentioned, is advantageous in numerous
ways and especially it is of great utility in the fixing of the pedestal and like
closets now in vogue, which otherwise is a very difficult operation.
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 :-
1. An improved joint, connection, or junction, for pipes or the like comprising
one or more telescopic lengths, with or without clamps and connecting or adjusting
screws or bolts, substantially as and for the purpose specified.
2. The improved joint or junction for pipes or the like constructed substantially
as described with reference to the accompanying drawings.
