IMPROVEMENTS IN PIPE COUPLINGS AND CONNECTIONS
Year: 1885

page_text: I ARTHUR ROLLASON of 5 Maddox Street London in the County of Middlesex
Engineer do hereby declare the nature of my Invention for IMPROVEMENTS IN PIPE
COUPLINGS AND CONNECTIONS to be as follows:-
This Invention relates to certain improvements in pipe couplings and connections
and has for its object to provide a means of coupling and uncoupling hose or other
pipes with great rapidity and with one hand only if necessary, thereby leaving the
other hand free to hold the hose or connections. No turning or screwing of the
parts is required, but the connection is effected by simply pushing one part of
the coupling into the other part. The general arrangement of the coupling consists
of what is known as the spigot and faucet arrangement By my improvements
inside the body of the faucet, I fit a spring clip composed of one or more sections
free to move in an annular groove. The clip is bevilled on one side and passes
round the greater part of the inside circumference of the coupling..
The ends of the sections project outside the coupling and are attached to the cap
or caps fitted to the lug or lugs of the coupling around the ends of the sections
I place a suitable spring to hold them together. The body of the faucet is made
longer than those in ordinary use and on the outside is screwed a thread of the
same size and pitch as ordinary fittings so that in cases of emergency any hose
fittings can be used. The inside of this extra portion serves as a guide for the
spigot part of the coupling which fits within it. On the outer side of the end of
the spigot a bevilled surface is formed to press in the clip and also a groove and
catch which engages with and holds the clip so that on the two parts being pushed
together the clip is first pressed in by the bevilled surface then springs out and
holds the clip and the connection is instantaneously and effectually made. To
release the coupling one lug only need be used but another lug is fitted to suit the
ordinary hose wrench or if desired two spring lugs can be fitted similar to couplings
already in use: by pulling the cap on the lug the sections of the clip are drawn
outwards and opened and the connections are released.

page_text: I ARTHUR ROLLASON of 5 Maddox Street, London in the county of Middlesex,
Engineer 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 certain improvements in pipe couplings and connections
and has for its object to provide a means of coupling and uncoupling hose or other
pipes, with great rapidity and with one hand only if necessary thereby leaving the
other hand free to hold the hose or connections.
By my improvements the coupling is interchangeable and can be used in con-
nection with any standard brigade fittings. The connection can be instantaneously
and effectively made by any unskilled person and the bose thus promptly made
ready for action. Standard brigade fittings can afterwards be connected if required,
without any loss of time, and without change or loose parts being required, as has
hitherto usually been necessary with ordinary fittings. The higher the pressure
within the pipe the less is the chance of leakage at the joint. To connect two
lengths of piping together no turning or screwing is required, and it is only
necessary to push the one part of the coupling into the other part; and immediate
disconnection is effected by simply pulling a cap or caps. The general arrange-
ment of the coupling consists of what is known as the "spigot and faucet
arrangement.
"
I will now proceed to describe my invention more fully by aid of the accom-
panying drawings, in which Figure 1, is a sectional plan through the centre of a
coupling; Figure 2, a cross section through the centre of a coupling fitted with
one lug; Figure 3, a vertical longitudinal section on centre line; Figure 4, a cross
section on line a, b, figure 3; and Figure 5, is a cross section through centre line
of a coupling fitted with two lugs. Similar letters indicate similar parts in all of
these figures.
The spigot part A is made of rather less diameter than the faucet or socket
part B, so that it can pass inside it as usual. The faucet part B is made rather
longer than those in ordinary use and may be tapered, and is provided with a screw
thread T, of the same size and pitch as ordinary standard brigade fittings, so that
in cases of emergency any available hose fittings can be used. The inner circum-
ference of this extra portion, serves as a guide to the spigot part A. Inside the
body of the faucet B, and passing round the greater part of its inside circumference
a spring clip C is fitted. This clip C, may be composed of any convenient number
of sections C and C', each capable of free movement in an annular groove D,
formed for that purpose in the body of the faucet. The clip C, is bevelled at one
side as shown, Figures 1 and 3, to facilitate the entrance of the spigot which is
constructed with a rim E at its extremity also bevelled on its outer edge, but
square on its inner edge. Behind this rim a groove F is formed so that when the
spigot is pushed into the faucet the passage of the rim E, presses the clip C, back
into the annular ring D, and the clip when released at once springs forward and
engages with the inner edge of the rim E, around the greater part of its circum-
ference, an almost continuous bearing being obtained, and the connection thus

page_text: instantaneously and securely made. The clip or sections of the clip is or are
operated by pulling outwards a cap J, or two caps J and J', provided for the
purpose upon the lugs S, S¹. Where one lug only S, is employed to operate the
clip a second dummy lug G, is also provided to suit any ordinary hose wrench.
When the clip is composed of two sections only as C and C¹, Figure 2, the
ends H, H, of the sections project outside the coupling and are suitably attached
to the cap. Around the parts HH, a suitable spring K is placed to hold them
together and press them forward. When the clip is composed of three sections the
part L of the upper section C³, projects outside, and is screwed or otherwise secured
to the cap J, and may be of the forin shown in Figures 4 and 5, having upon each
of its lower arms a pin m, projecting into a slot N, formed in the adjoining sections.
The lower ends of the sections C and C', may be formed jointed and secured by
rivet O, Figures 3 and 4, or may be made as shown in Figure 2, slotted and
maintained in position by the pins m, m, so that a pull on J, will cause them to be
drawn upwards and pressed back into groove D, and so opened; or where two lugs
and caps are required as shown in Figure 5, the lower parts H, H., may also be
projected outside the coupling and secured in a similar manner to that above
described where a single lug only is used; or by another arrangement instead of
the pin and slots 'm, and N, aforesaid, the ends of the sections C, C¹, and C², may
be formed as shown dotted at p, p, Figure 4, to produce the same result.
The couplings may be fitted with Hanges, or necks, or screwed, or not, or made
with any other suitable connection for hose or pipes, and India rubber Gutta
Percha, Leather, or other suitable substance may be used in the joint if desired as
Blown at R.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is
(1.) A screw T formed on the end of the body of the faucet or socket part of a
coupling capable of use with any ordinary hose connections substantially as and
for the purposes described.
(2.) The use of a spring clip constructed and operated as described for the purpose
of instantaneously effecting a tight joint and ensuring a firm grip and continuous
bearing round the greater part of the said joint, all arranged substantially as
described.
