Improvements in Pipe Connections.

I, ROBERT STRETTON, of 23, Hindon Street, Pimlico, London, S.W., Gentleman,
do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in pipe connections more particularly
intended for connecting or securing together beer pipes or tubes, the object being
to provide simple and effective means for firmly securing the ordinary rubber
connecting sleeve in place, and at the same time to ensure a more secure and
perfect joint than has hitherto been obtained by the methods of connection hitherto
employed.
In carrying my invention into practical effect, the tubes to be connected are
butted or flanged at their extremities, and the ends of these tubes are inserted in
a rubber sleeve of sufficient length, while instead of binding the sleeve tightly
against the outer peripheries of the tubes by winding wire round same in the
manner at present employed, I take a suitable length of preferably steel wire and
formed with a head at one end. Each length of wire is passed through a hole
or perforation in a small metal plate and extends around the rubber sleeve, the
extremity of the wire then passing through a second hole or perforation in the
said plate when it can be sufficiently tightened up, to cause the sleeve to tightly
grip the tube, by means of a suitably shaped nut engaging with the extremity of
the said wire, which is screw threaded for this purpose.
By means of this invention the binding wire may be tightened up to almost any
extent, while it further allows of any tube being quickly and easily removed
when required.
Although I have described this invention as more particularly intended for use
in connection with joints for beer pipes or tubes, it is obvious it may also be
employed for joining other pipes or tubes together where this method of connection
is attended with advantageous results.

be performed, to be particularly described and ascertained in and by the following
statement—
My invention relates to improvements in pipe connections more particularly
intended for connecting or securing together beer pipes or tubes, the object being
to provide simple and effective means for firmly securing the ordinary rubber
connecting sleeve in place, and at the same time to ensure a more secure and
perfect joint than has been obtained by the methods of connection hitherto
employed.
In carrying my invention into practical effect, the tubes, to be connected are
butted or flanged at their extremities, and the ends of these tubes are inserted in
a rubber sleeve of sufficient length, while instead of binding the sleeve tightly
against the outer peripheries of the tubes by winding wire round same in the
manner at present employed, I take a suitable length of preferably steel wire and
formed with a head at one end. Each length of wire is passed through a hole
or perforation in a small metal plate and extends around the rubber sleeve, the
extremity of the wire then passing through a second hole or perforation in the
said plate when it can be sufficiently tightened up, to cause the sleeve to tightly
grip the tube, by means of a suitably shaped nut engaging with the extremity of
the said wire, which is screw threaded for this purpose.
By means of this invention the binding wire may be tightened up to almost any
extent, while it further allows of any tube being quickly and easily removed
when required.
In order that my invention may be more fully understood, I will now proceed
to describe same with reference to the accompanying drawings in which;-
Fig. 1 shows in detail the parts of the tightening device.
Fig. 2 shows a side view and plan of a tightening device.
Fig. 3 illustrates the extremities of two pipes or tubes to be joined with the
sleeve used in connection therewith, and
Fig. 4 is a view of the completed joint.
According to this invention, the tubes t to be connected together are preferably
butted or Hanged as shown (Fig. 3) and the ends of these tubes are inserted in
a sleeve r of india-rubber or other suitable material and of sufficient length. Over
each end of the sleeve is then passed one of the tightening devices as shown in
Fig. 2, each of which comprises a sufficient length of wire w furnished at one
extremity with a head a, the other extremity being screw threaded as shown at w¹³.
The wire wis passed through one of the holes in the plate 2 when it is bent
into circular form and repassed through the second hole or perforation in the
said plate, the projecting screw threaded extremity w being then furnished with
a nut or nipple such as n, which may be of any convenient shape, for the purpose
in view, and which when revolved in the required direction draws the extremity w
of the wire a through the plate p thereby reducing the diameter of the ring into
which the said wire is formed.
In this manner as shown in Fig. 4 the sleeve is tightened on to the tubes t so
as to cause it to closely embrace the outer peripheries of the tubes thereby making
a firm and secure water-tight joint, while either of the tubes may be quickly and
easily removed by releasing the nut or nipple n.
Although this invention is more particularly intended for joining or connecting
together beer pipes or tubes, it is obvious that the same method of tightening a
sleeve upon the outer peripheries of tubes to be joined may be employed with
pipes or tubes of any other description, where this method of connection can be
advantageously employed, while it is also applicable to the connection of garden
hose, or other tubes of this kind.
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:
