Automatic Hose Pipe Connection.
WILLIAM FRASER Engineer Glenholme 99 Anderton Road Sparkbrook
Birmingham do hereby declare the nature of this invention to be as follows:-
The object of this invention is the construction of a hose pipe connection and
tap union with coupling sleeves the same being actuated by a spiral spring for the
purpose of effecting an instantaneous connection.
In carrying out said invention the connection for coupling two hose pipes
together is fitted with two loose sleeves with a spiral spring between them, .e. the
body part of the coupling has a parallel part in the centre on which the two
sleeves slide backwards and forwards the spiral spring being placed between the
same and of sufficient length and strength to always keep them as far apart as to
cover the coupling or bulbous tails. To make a connection either of the sleeves are
pressed back on the spring which becomes compressed and gives way under said
pressure, the hose pipe is then slipped over the bulbous tail and the moment the
sleeve is let go the spiral spring forces the same back again over the bulbous tail,
the hose pipe being caught between the two the moment the pressure is relaxed,
the sleeve on the other end is forced back in the same manner as already described,
a connection can thereby be effected instantaneously without having to wire the
hose on to the coupling tail. The parallel part of the coupling has a small collar
at each end of same for the purpose of preventing the two sleeves coming off or
becoming disconnected from the body part, thus the whole of the different parts
are kept together and cannot therefore be lost when not in use, and when in use
the pressure of the spring being always upon the sleeves prevents them being
forced or sent back in any way when the pipe is being dragged about.
To make a union with a bib tap one end of the connection is as already described
but the other end is fitted with an india rubber ring or washer for the purpose of
effecting a joint with the water tap.
It is obvious that the connection is suitable for all kinds of flexible piping
feeding bottles and the like.

Automatic Hose Pipe Connection.
1, WILLIAM FRASER, of Glenholme, 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 :-
This invention consists in the construction of a hose-pipe connection and tap
union with coupling sleeves actuated by a spring whereby an automatic and
instantaneous connection is effected.
In carrying out my said invention, the connection for coupling two hose pipes
together, is fitted with two loose sleeves with a spiral or equivalent spring between
them, the body part of the coupling having a parallel part in the centre on which
the two sleeves slide backwards and forwards, the spiral spring being placed
between the same, and of sufficient length and strength to always keep them as far
apart as to cover the two coupling bulbous tails or parts, provided at each end of
said body. To make a connection, one of the sleeves is pressed back whereby the
spring is compressed. The hose-pipe is then slipped or pushed over the bulbous
[Price 8d

page_text: tail or end, and the sleeve is then released, whereupon the spiral spring forces it
back again over the bulbous tail or end, the hose-pipe being thereby instantly
caught or clipped between the two, parts, that is, between the exterior of the
bulbous tail and the interior of the sleeve. The sleeve on the other end is forced
back in the same manner as the one just described. Thus a connection can be
effected instantaneously witliout any other operation.
The parallel part of the coupling, has a small collar at each end of same for the
purpose of preventing the two sleeves from coming off or becoming disconnected
from the body part; thus the whole of the different parts are kept together and
cannot therefore be lost under any circumstances. The pressure of the spring
being always exerted upon the sleeves, it prevents them being forced back in any
way when the pipe is being dragged about, or in the event of it coming in contact
with anything.
To make a union with a bib-tap, or otlier supply conduit or device, one end of
the connection is constructed' as above described, but the other end is fitted with an
india rubber ring or washer for the purpose of effecting the joint with the water
tap or other supply conduit.
It is obvious that the connection is suitable for all kinds of piping or tube, and
that the union end and rubber washer is suitable for all kinds of connections,
namely, bib-taps, or for connecting lengths of hose-pipe together by employing a
piece of metallic tube in connection with the hose-pipe and connecting such piece
of tube with the rubber washer of the union. Or, again, the top part of the union
(that is the part having within it the rubber ring or washer) can be used in
connection with filters for the purpose of connecting them (filters) to bib-taps, or
to other conduits or devices or connections; that is to say, the part of the unión
consisting of the rubber washer and its containing shell (hereinafter described
with reference to the drawings) can either be used separately under this invention,
or in conjunction with the hose-pipe connections herein described.
In the drawings which serve to illustrate my invention, I shew, in Figure 1, an
elevation partly in section of the improved fitting for fixing a hose-pipe to an
ordinary house tap or other water or other fluid supply conduit and in Figure 2
an elevation shewing the improved fitting for coupling together two links of hose
or other pipe.
or'
The examples of my invention shewn in the drawing are made of sheet or pliable
metal pressed or struck up into the form shewn by any suitable known kind of
and
tools machinery for pressing, spinning, or equivalently working upon sheet
and other pliable metal-such for instance as brass. This is the preferred form or
construction of my improved connections, as it affords several advantages; for
instance, its cost of production is considerably lower than when or if otherwise
made, as the different parts do not require turning or fitting, and it is moreover
lighter, that is, the weight of metal in it is less than if otherwise made.
In the drawings, is the body or throat pipe, having at one end, or at each end,
as the case may be, a bulbous part pressed or worked out into the form shewn by
any suitable known ieans, and over which the hose pipe or tube is placed when
connecting it up; are the sliding spring-pressed gripping sleeves which are
stamped or otherwise pressed out of sheet or pliable metal into the form shewn ;
and are the springs by which the sleeves care automatically pressed up into
position and grip the hose-pipe, which is designated e.
It will be seen the sleeves e have necks c, which is the part of them which slides
directly on the body a; and that they are flanged over at c³ to receive and form a
seat for the end of the springs d. The throat body a is provided with a projecting
collar b¹ which forms a stop against which the necks e¹ of the sleeves care pressed
by the springs d, and by which such sleeves are held in position; said collar being
pressed or worked out into the form shewn' by suitable known tools or machinery.
In making, the sleeves are slipped onto the body a prior to the pressing up-or-out
of the second' tail b and collar b

page_text: The end t, shewn in Figure 1, by which the coupling is attached to an ordinary
tap mouth, or end of a pipe, or other fluid supply conduit, consists of a ring of
india-rubber, t, held in the hollow neck or shell 2 pressed or stamped or worked
into the form shewn, from brass, steel or any other pliable metal. The neck is
slipped over and fixed onto the pipe a as shewn. To attach this end to a tap or
other pipe or conduit, it is simply pressed onto the tap mouth or pipe in the well
known way.
When this neck is applied to filters for connecting them to bib-
taps, etc., the narrow part is threaded and screwed onto the filter, or soldered, or
otherwise secured thereto.
In operation, to connect a hose-pipe to the coupling, either of the sleeves e is
pressed back by the hand, and the pipe is then slipped over the bulbous end b of
the body or throat pipe a. The collar is then let go; whereupon the spring d
presses the pipe onto the bulbous part b and retains it there, making a water-tight
joint, and automatically, without any screwing up of parts, or other hand mani-
pulation. This automatic operation renders couplings very easy to connect and
manage, and the action moreover is done very rapidly; and by this invention many
of the drawbacks of couplings heretofore employed, wherein the parts had to be
screwed up, wired up, or otherwise turned, or manipulated, are entirely obviated.
Reverting to the construction of the couplings or unions out of sheet or pliable
metal (such for instance as brass), the sleeves of the coupling may be struck up or
stamped out of sheet metal by male and female dies, or spun into shape whilst
revolving in a lathe or other suitable machine, or they may be forced into shape by
other suitable tools. The shell of the union above described for containing the
rubber ring or washer, can also be made in a similar way and by a similar means.
The parallel part or body a of the coupling or connection, is made by employing a
piece of tube, and forcing the bulbous tails or parts b, and the collars or rings b',
out into the formations shewn by pressing or working the tube from the inside by
suitable tools.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, it is to be understood that the
invention is not confined to the particular form of spring and other parts shewn in
the drawings, but what is claimed in respect of this invention is:-
1. The herein described improvement in hose or other pipe fittings or couplings,
that is to say, a fitting or coupling wherein a spring or springs is or are adapted to
act upon a sleeve or equivalent part thereon, and cause a water tight joint between
the body of said fitting or coupling and the hose or other pipe to be made,
substantially as set forth.
2. The hose or other pipe fittings or couplings comprising the body a, sliding
sleeve or sleeves c, spiral spring d, and bulbous end or ends b, constructed and
adapted to operate as set forth with reference to and shewn in the accompanying
drawings..
3. The improved hose-pipe or other coupling or fitting herein set forth with
reference to the drawings, that is to say, a coupling or fitting comprising the parts
specified of sheet or pliable metal pressed, stamped, spun, struck-up, or otherwise
similarly swaged or worked into the different formations described; substantially as
and for the purposes set forth.
4. The improved connection by which hose-pipes, filters, or things of a similar
kind, may be attached to bib-taps and other conduits, consisting of the union or
connection shewn in Figure 1, comprising an india rubber or equivalent washer t¹,
and shell or neck with a contracted end, within which said washer is fitted and
held for the purposes set forth.
