Improvements in or relating to Pipe or similar Couplings.
We, JOSEPH HENRY MILES, General Fitter, 47 Granby Place, Lower Marsh,
Lambeth, JOSEPH DIMON, Porter, 1 China Walk, Lambeth, in the County of
Surrey, and JOHN JONES, of 40 Sydney Street, Chelsea, in the County of
Middlesex, Builder, do hereby declare the nature of this invention to be as
follows:
-
This invention relates to couplings or connections for pipes of various kinds
particularly flexible pipes which may be connected to metal pipes or connections or
two of the rubber pipes may be connected together.
In making the connection between a rubber pipe and a metal one, the projecting
end or nozzle for example of a tap or a fixed piece of pipe from the cistern or the
like, we employ a coupling formed in two parts one adapte.l to fit over the rubber
pipe and the other over the metal pipe. The metal pipe would be adapted to fit
inside the rubber pipe and should have some means by which the rubber could take
a firm hold upon the metal as for example oue or more rings or grooves or a collar
or the end of the metal pipe may be enlarged to a larger diameter than the rest.
The rubber pipe is pushed over the end of the metal pipe after the couplings are in
place and the couplings are then screwed up, the effect being to swell the rubber so
as to cause it to tightly fill the whole of the space between the interior of the
coupling and the exterior of the metal pipe. Both couplings may be recessed and
tapered internally or either of them may be provided with tapered or other
washers whether of metal leather or other material. One or both of the couplings
may be provided with Hats, projecting pins or the like by which they may be
turned or held so as to obtain sufficient power in screwing the couplings
together.
In connecting the flexible pipe to a metal pipe or connecting ferrule substan-
tially the same plan already described is adopted.
In connecting two pieces of flexible pipe the couplings are substantially the
same as already described and a metal or equivalent ferrule or hollow plug is placed
partly in each of the pipes to be connected and when the couplings are screwed up
the flexible pipe is compressed between this hollow plug and the couplings and a
tight joint thus obtained.
Various modifications may be made to suit special applications but the same
principle would be carried throughout.

Improvements in or relating to Pipe or similar Couplings.
We, JOSEPH HENRY MILES, General Fitter, 47 Granby Place, Lower Marsh,
Lambeth, JOSEPH DIMON, Porter, 1 China Walk, Lambeth, in the County of
Surrey, and JOHN JONES. of 40 Sydney Street, Chelsea, in the County of
Middlesex, Builder, 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 relates to pipe or similar couplings or connections to enable
flexible or other pipes to be coupled together or to the nozzles of taps, for example,
and it is of particular advantage in its application to india-rubber pipes or to hose,
although it is not limited to such application.
In the accompanying drawings, which are partly in longitudinal central section
and partly in elevation,
Fig. illustrates one construction of coupling according to this invention,
employed to connect two rubber tubes together;
Fig. 2 illustrates a stuffing-box coupling according to this invention;
Figs. 3 and 4 show two constructions of our improved coupling as applied to
connect a cock to one end of a rubber tube.
Fig. 5 shows the improved coupling as applied to connect a water-hose with a
water-tap.
Figs. 6, 7 and 8 are views of separated details of the apparatus shown connected
up in Fig. 5; and
Fig. 9 shows the improved coupling in combination with a well-known type of
tap-nozzle coupling.
Like letters indicate like parts throughout the drawings.
In all the modifications illustrated, two sleeves A and B adapted to engage with
each other are placed on the pipe C or pipes CC. These sleeves have a bore
approximately equal to the normal external diameter of the pipes, and one of them
is placed above and the other below the intended position of the joint. Within the
tube or tubes at the joint is inserted a device D to afford internal support to them,
the tube or tubes being formed with an annular swell or enlargement where they
encircle the device D, such enlargement being imparted to them by forcing them
over the device D or otherwise expanding them. When the device D is in place
as shown, the sleeves A and B are caused to engage and are forced towards each
other into the positions in which they are shown in Figs. 1, 2, 3, 4, 5 and
drawings so that the pipe or pipes they encircle are gripped tightly between them
and the device D as illustrated in such a manner that there can be no leakage
past their meeting surfaces, which may be coned or tapered if desired, as indicated
in the drawings or otherwise.
of the
The sleeves A and B are provided with male and female threads so that they
may be readily engaged and disengaged, and one or both of them may be formed
externally as a hexagon out, or provided with wings B¹ (Figs. 1, 5, 6 and 8) or
with flats" to enable the sleeves to be held or turned manually or by the usual
tools. One of them, preferably the sleeve B having the female thread, is provided
with a gland or ring B2 to bear against the pipe on which the sleeve is placed
grooved at B 3 to receive a flange B4 on the screw-threaded body of the sleeve so
that although the gland and body are always connected the latter will rotate about
the former when the sleeves are being screwed together, but the gland will not
rotate upon the pipe. Thus all tendency to twist the pipe or to injure it by
rotating the sleeve B about it in the operation of making the joint is avoided.
The sleeves A B and gland B2 may be bevelled or cut away as at A5 B5
respectively, so as not to cut into the pipes they encircle.

page_text: In the modification illustrated in Fig. 1 the device D is a ring bevelled at both
ends and extending into both the pipes C C' so that the swell or enlargement is
obtained from the two.
In the modifications illustrated in Figs. 2, 3 and 4 the device D consists of a
tapered and swelled nozzle formed as part of the tap E or other appliance to which
the pipe C is connected. Preferably this device should be grooved as in Figs. 2
and 3 or beaded or provided with thickened lips or ends (as in Figs. 5 and 9) to
improve the grip of the pipe upon it.
The sleeve A may be internally screw-threaded as at Figs. 2 and 3, to enable it
to engage with corresponding threads formed on the pipe it encircles.
In the modifications shown in Figs. 5 and 9 the device D and sleeve A are in one
piece with a space between them to receive the end of the tube C. In the former
instance the combined device D and sleeve A are brazed or otherwise secured
to a tap E; in the latter instance they are integral with a well-known type of
union F.
Instead of being connected by screw-threads the sleeves A and B might be
connected by a bayonet joint if desired.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is ;-
1. In pipe or similar couplings the combination with a device such as D of
sleeves A and B adapted to engage each other substantially as and for the purpose
described.
2. In pipe or similar couplings such as described the combination with a sleeve
such as A or B of a gland or ring B2 substantially as and for the purpose
described.
3. In pipe or similar couplings such as described a device such as D and sleeve
such as A integral with each other substantially as and for the purpose
described.
4. The combination and arrangement of parts constituting a complete pipe-
coupling or the like substantially as and for the purpose described and illustrated
in Figure 1 or Figure 2 or Figure 3 or Figure 4 or Figures 5, 6, 7, and 8 or
Figure 9 of the accompanying drawings.
