Improvements in Couplings for Hose Pipes, and in the Manufacture
of the same.
We JOHN DUNNELL GARRETT of The Firs, Middleton Hall Road, Kings
Norton, in the County of Worcester, Engineer and WILLIAM HENRY CATER, of
6 Trafalgar Place, Bissell Street, Birmingham, in the County of Warwick Brass-
founders Foreman do hereby declare the nature of our said invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :--
Our invention has for its object improvements in couplings for hose pipes and in
the manufacture of the same which are so designed and constructed that large hose
pipes may be connected thereto and coupled together without any lapping or
complication almost instantaneously and while our invention is intended for use
more especially for coupling large textile water hose pipe for such like purposes
as, fire engines and ships it may also be used for general purposes if so desired.
In order that our invention may be clearly understood and more easily carried
into practical effect, we have appended hereunto a double sized sheet of drawings
upon which we have illustrated the same in its various parts and also as showing
those parts brought together to form the complete coupling but it will be clearly
understood that the general configurations may be varied so long as the main
principle is adhered to.
Figure 1. shows our hose coupling A in elevation with its end fittings connecting
it with the lengths of textile hose piping H and H'.
Figure 2. is a sectional plan of the coupling A and its connections and showing
the manner. of uniting the hose H and H.
Figures 3. show the centre tube T and the end glands E and El disconnected.
Figures 4. show the coupling or centre part A as well as the end pieces B and B¹
disconnected from each other and the part A before its ends are turned down.
We have said that our new hose coupling is principally intended for the purpose
of uniting lengths of textile hose piping together of large diameter such for instance
as that used for fire engines and ship purposes. We have shewn two lengths of
hose H and H united together by the coupling so that a perfectly clear and free
passage for the flow of the water is maintained. as will be seen at the sectional plan
Figure 2. The main or outer body or case of the coupling is A which is made
with the ends a straight in the first place until the screw thread has been cut
through the inside and the ends B and B are entered a certain distance when the
ends a of A are spun or tooled down as seen in the section Figure 2. The ends B
and B are screwed at to correspond with the internal thread of A and each end
piece has au enlarged milled bend to enable the hands to take a firm grip upon
them. The internal tube T is plain when the parts are brought together or one
of the bulges may be formed first but generally T would be plain and the
bulges t would be formed when the parts are together by tools or by spinning
The glands E and E¹ may be made by spinning or cupped in tools or cast to a
similar shape to that shown in section at Figure 2. the bottom portion being
necked or contracted at e with its tapering part e and its hooked outer curl
which will be noticed to clip a head though a flat flange would answer the
purpose, but in any case we prefer the milled bead 64 to project some distance
beyond e so as to protect it from injury when the hose is being handled.
In putting the parts together one mode of proceedure is to run the ends B
and B a convenient distance into A and then the ends a² of A are beut or

page_text: worked down as shown at Figures 1 and 2. Then the tube T as seen at
Figure 3. is put in and the glands E passed over it after which the bulges t¹
are formed in T when the whole of the parts are loosely secured together.
To secure the textile or other hose H, H' in position it is only necessary to run
the ends B and B inwards in A sufficiently to leave the glands E and E
sufficiently loose to pass onto the hose. Immediately the hose H and H* are
passed in the ends B and B are screwed outwards when they carry the glands E
and E with them and tighten and lock the hose H and H' between the bulges t¹
of T when the junction is made.
These couplings may be made of brass or any suitable metal or material for the
purpose.
At Figure 5 we show a modification of the glands E by which we form the
ende larger so as to turn out the end of the hose H into bell mouth shape thus
more effectively fastening the hose.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
First. The improvements in couplings for hose pipes, and in the manufacture
of the same consisting of the tube T with its glands E, E¹ and outer ends B,
and B, tightened upon the hose by means of the screwed casing A substantially
as and for the purpose herein set forth and shown upon the accompanying
drawings.
Second. In hose couplings the combination of parts consisting of A and its
connecting ends B and B acting upon the glands E and E' in combination with the
bulged tube T as and for the purpose herein specified & shown.
