PROVISIONAL SPECIFICATION.
Improvements in Hose and other Pipe Connections.
WILLIAM FRASER Engineer 45 Bull Street Birmingham do hereby declare the
nature of this invention to be as follows :-
The object of this Invention consists in improvements in connections for flexible
and other hose pipes, speaking tubes, feeding bottles, soft metal pipes-and the like-
without making a wire, soldered, or screw joint.
In carrying out one form of my Invention I make use of a double coupling tail
with bulbous ends, with a collar midway between same (either with or without
capstan arms) at each side of said collar is a screwed part about one inch or
thereby, for engaging with the coupling sleeve, same thing made in two seperate
parts with one part rolled into the other to make them really one-although
seperate-i.e. to roll one part into the other and form a swivel or revolving joint
between the nut and the sleeve, thus, the screwed part can be revolved without
causing the sleeve to revolve when making a joint. The principal object in this
form of my Invention is that the two bulbous tails and the collar between with the
screwed part on each side of same can be cast or made in one part, then turned,
screwed, and finished at one handling; the nut and sleeve combined being really one
piece is then attached at each end, i.e., the screwed parts of the sleeve engages with
the screwed parts between the bulbous tails and the centre collar, thereby keeping
all the parts together, and preventing same from being lost or becoming loose parts.
Another form of my Invention is in having it applied, with a slight modification
for childrens feeding bottles by having a groove cut on the inside of the bulbous part
and having a loose ring to clip the hose in said groove.
Another form of my Invention is to have two bulbous tails with a parallel piece
between, and without a collar in the centre and to have the two sleeves screwed inale,
and female, one of them having a swivel or rolled in revolving joint; then to connect
two pieces of hose pipe the one sleeve would be screwed in-to the other, the hose
slipped over the bulbous tails in the ordinary way, then reverse the sleeves by
screwing them in opposite directions thereby making a fast and perfect joint.
Another form of my Invention is in having the bulbous tails tapered from the ends
to the centre, and in having the two sleeves screwed male and female, but in making
a joint they must be screwed from one another as far as to allow the hose easy
access between same and the inside tapered ends, then by screwing the two sleeves
together the hose is gripped and a thoroughly fast joint made.
Another form of my Invention suitable for soft metal pipes in particular consists in
having two tapered tails with an oblong ball piece between same fitted with male,
and female, ring. To make a joint, loosen the rings then the pipe can be slipped
over the tapered ends, i.e. it is put in between the rings and the tapered ends then
by reversing the screw a perfect joint is made.

COMPLETE SPECIFICATION.
Improvements in Hose and other Pipe Connections.
WILLIAM FRASER Engineer Glenholine Anderton Road Sparkbrook Birmingham
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 :-
The object of this Invention consists in improvements in connections for flexible

page_text: and other hose pipes, speaking tubes, feeding bottles, soft metal pipes and the like,
without making a wire, soldered, or screw joint. In carrying out one form of my
Invention I make use of a double coupling tail with bulbous ends, with a collar
midway between (and either with or without capstan arms).
At each side of said collar is a screwed part about one inch or thoroby long for
engaging with the coupling sleeves, said sleeves being made in two separate parts
with one part rolled into the other to make them really one, ie. by rolling one part
into the other they form a swivel or revolving joint between the nut and the sleeve,
thus, the screwed part can be revolved without causing the sleeve to revolve when
making a joint.
The principal object in this form of my Invention is, that the two bulbous tails and
the collar between with the screwed part on each side of same, can be cast or made
in one part, then turned, screwed, and finished at one handling; the nut and sleeve
combined being really one piece after being rolled together, it is then attached to each
end, e. the screwed parts of the sleeve engages with the screwed parts between the
bulbous tails and the centre collar, thereby keeping all the parts together, and
preventing same from being lost, or becoming loose parts.
Another form of my Invention is in having it applied (with a slight modification)
for childrens feeding bottles, by having a groove cut on the inside of the bulbous
part, and having a loose ring to clip the hose in said groove.
Another form of my Invention is, to have two bulbous tails with a parallel piece
between, without a collar and fitted with sleeves the same as already described.
Figure I represents in horizontal section a hose pipe union. The same letters of
reference indicate corresponding parts in the various figures. A and A' are seperate
coupling tails. B is a collar to enable the coupling to be held when making a
connection or disconnection. is an internally screwed nut. 1) is a bell mouthed
sleeve for engaging with or clipping the hose when the coupling sleeve is sent forward
on A. The parts marked (" and D' being rolled into one another to form the swivel
or revolving joint.
To make a joint the pipe is slipped over A the coupling being hold by B then by
revolving the nut C sleeve D is sent forward and grips the pipe between interior of
the former and the exterior of the latter joint. The same arrangement can be applied
to the other end, thereby making a double coupling being suitable for a double or
single coupling.
Figure 1 is a double coupling without a centre collar and would be a
modification of figure IC being an internally screwed nut with the sleove D rolled
into it to connect both together. It will be observed that the rolled in joint is
vice-versa as compared with Figure 1. It is obvious that this joint can be made in
many different ways, for example, a screwed pin could be applied to hold the nut
and sleeve together, but it is quite immeterial as to how and what way the joint is
made so long as the nut and sleeve are attached together, and will not seperate
and providing also that the nut can be revolved at the same time.
Figure 111 is a modification of Figure 1 and II the ring D) is drawn forward on A
and makes a joint on the groove A¹.
Having now particularly described and ascertained the nature of said Inven-
tion and in what manner the same is to be performed, 1 doclare that what I
claim is ;
First. In moving forward the sleeves of hose or other unions, by means of a nut
and sleeve with a rolled in joint D' and C' as already described and set forth in
Figures I and II respectively.
Secondly. In having a coupling as shown in figure III with a loose ring D and
groove Aas already described and set forth.
Lastly. In having the particular combinations, described, illustrated and set forth
in the various figures of the drawings.
