Improvements in Couplings for Taps or Tubes.
I, THOMAS DIPPLE of 69, Bloomsbury Street Birmingham, in the County of
Warwick "Manager of Works" do hereby declare the nature of this invention to be
as follows:
It has for its object "Improvements in Couplings for Taps or Tubes, it is so
constructed that it can be readily adjusted without the ordinary method of having
screw worm on articles where it is necessary to make a joint. There is a cap with
hole in top and screw worm on bottom, inside of which I insert an india rubber or
flexible ring or washers. On the said screw worm is fitted another cap of any
convenient shape, inside of which is adjusted a pipe with a projection at top, which is
brought against the india rubber or flexible ring or washers aforesaid. When bottom
cap is tightened on top cap it so compresses the india rubber or flexible ring or
washers, that it reduces the hole, by which means it clips any article, and makes a
staunch and substantial joint, which cannot be dis-connected only by loosening bottom
cap which allows the hole in india rubber or flexible ring or washers to return to its
ordinary size and loose its hold.

I THOMAS DIPPLE of 69 Bloomsbury Street Birmingham in the County of Warwick
Manager of Works do hereby declare the nature of my said 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 improvements in couplings for taps or tubes it is so
constructed that it can be readily adjusted without the ordinary method of having
screw worm on articles where it is necessary to make a joint. There is a cap with
hole in top and screw worm on bottom inside of which I insert an india-rubber or
flexible ring or washers.
On the said screw worm is fitted another cap of any convenient shape, inside of
which is adjusted a pipe which a projection at top which is brought against the india-
rubber or flexible ring or washers aforesaid.
When bottom cap is tightened on top cap it so compresses the india-rubber or
flexible ring or washers that it reduces the hole by which means it clips any article
and makes a staunch and substantial joint which cannot be disconnected only by
loosening the bottom cap which allows the hole in india-rubber of flexible rings or
washers to return to its ordinary size and loose its hold.
In order that the invention may be carried into practice without difficulty I have
illustrated one example of its application to an ordinary tap which will be quite
sufficient to make other applications clear as the principle is the same in all cases.
Figure 1 is a longitudinal section of my coupling showing all the parts complete in
their proper position before it is placed upon the tap.
Figure 2 shows the tap and coupling united to each other in the manner about to
be explained.
The coupling is generally composed of four pieces viz. the hose spigot A the
internal nut B the rubber or other elastic or flexible washer C and the washer box D.
The washer C may be composed of a number of thin rings instead of one if so
desired. The hole or entrance d¹ to the washer box D is sufficiently large to receive
the nose e¹ of the tap E easily and the washer C when in its normal condition as
shown in Figure 1 also allows the nose e¹ to enter loosely to nearly the end of C.
When this is done the internal nut B is screwed forward by means of the pro-
jections b' and b² operated by one hand while the projections d2 and d³ are held by
the other hand to prevent the part D from turning. This operation reduces the
length of the washer C which is confined between a and d¹ and forces it to bulge
inwardly as shown by the dotted lines c' and e² which bite the outer surfaces of the

drawal of the nut B releases the junction piece. It will thus be seen that the
application may be made to an ordinary plain nosed tap or other article without any
special formation or provision whatsoever. It is of course: possible to make A. and B
in one piece.
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 :-
The improvements in couplings having a washer C operated by the parts A. B and C
substantially as and for the purpose herein set forth.
