COMPLETE SPECIFICATION.
Improvements in Joints applicable for Coupling Pipes or Tubes, and
for other purposes.
We, THOMAS DODD and GEORGE OULTON, both of Granite Buildings, Stanley
Street, Liverpool, in the County of Lancaster, Brass Founders, 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 has for its object an improved joint for coupling pipes
such as an india rubber tube to a metal pipe, or an india rubber tube to a hot
water tap or nozzle. The joint may also be employed (among other purposes) for
coupling a handle to a cord or chain pull, such as are used for the feed valves of
shower baths, lavatories or water closets.
or tubes,
The invention is best described by aid of the accompanying drawings, in
which:-
Figure 1 is a sectional elevation of our improved joint, applied to coupling an
india rubber tube to a hot water tap or nozzle; and
Figure 2 an elevation partly in section of a pull handle showing the joint for
attaching same to the pull chain.
Referring to Figure 1: A, is the nozzle of a hot water tap, B india rubber pipe,
C flexible joint ring D a screw cap and E washer. The end of the nozzle A is
provided with a collar c and a sleeve or neck c'.
A groove in proximity to the
Coilar c is formed in the periphery of the neck c¹.
The mode of making the joint or coupling is as follows:-
The neck c having been slipped into the rubber tube, the flexible ring C is
placed in position on the end rubber tube B immediately over the groove in the
neck c¹; the cap D is then screwed on to the collar c compressing the joint ring
against the washer E, and forcing it and the end of the rubber tube into the groove
in the neck c¹. The washer E can be omitted if desired.
Referring to Figure 2: A is the handle, B the socket or cap_to which the
pull chain is attached, C the india rubber ring, D an annular collar, E a groove cut
in the periphery of the handle into which can be inserted the elastic ring C
preferably of india rubber whose outside diameter when in place is greater than the
diameter of the end of the handle. The socket D having been slipped on to the
handle A, the elastic ring C is sprung into position in its groove whereby
the socket is prevented from being removed owing to the shoulder at its end. To
the socket is screwed or otherwise secured, the cap B to which the cord or chain
pull is attached, and it is preferably so arranged that when the parts are in position
the end of the cap B and the face of the shoulder of the socket D bear against and
compress opposite faces of the elastic ring, whereby the handle is held firmly and
cannot shake about therein.
We have mentioned these ways of jointing or coupling an india rubber tube to a
metal pipe or an india rubber tube to a hot water tap or nozzle, or a handle to a
cord or chain pull such as are used for the feed valves of shower baths, lavatories or
water closets, but it is obvious that once given the general idea, other ways can be
designed for the purpose.

page_text: Having now particularly described and ascertained the nature of our sai
tion and in what manner the same is to be performed, we declare that wi
claim is :-
The general combined arrangement or construction of parts, forming the improved
joint or coupling substantially as described.
