COMPLETE SPECIFICATION.
Improvements in Couplings for Garden-hose and other like Tubing.
1, GEORGE STRETTON SPURRIER, of Barton House, Manchester, in the County
of Lancaster, Merchant, 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 improvements in couplings for garden hose and other
like tubing. In carrying out my said invention I employ a straight piece of metal
pipe screw-threaded externally excepting near its two extremities which are of
bulbous form. On the screw-threaded part are two screw nuts in the form of bell-
mouthed cups whose openings or mouths point away from each other. The ends of
the garden hose or other tubing having been pressed over the bulbous extremities
of the coupling pipe the cups are screwed up in opposite directions so as to enclose
and compress the ends of the tubing against the inner sides or surfaces of the bulbs
and thus the required water-tight joint is made. To uncouple the joint the cups
are unscrewed when the tubing may readily be withdrawn or detached from the
coupling.
In order that my invention may be better understood reference is hereinafter had
to the accompanying sheet of drawings wherein :-
Fig. 1 is an elevation and
Fig. 2 a longitudinal section of the improved coupling shewing the parts in
the positions which obtain when the joint has been made as above described.
Fig. 3 is a longitudinal section of the coupling with the tubing removed.
a is the straight piece of screw-threaded pipe having the bulbous shaped ends bb
and the bell-mouthed screw nuts c e-d d representing the garden hose or other
tubing. The outer edges of the cups cc are preferably milled or roughened to
facilitate the turning round of the said cups by hand or between the finger and
thumb.
Figs. 4 and 5 illustrate a method of adapting my invention in conjunction with an
ordinary form of attachment i to the purpose of coupling up to the nozzle of a
water-tap T.
At Fig. 5 the bulbous part of the pipe a is shown (in section) with a concentric
groove into which is inserted an elastic ring h-preferably round in cross section-
for the purpose of facilitating the making of a water-tight joint.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A coupling for garden hose or other like tubing consisting of a screw-threaded
length of pipe baving bulbously-formed ends and cups or bell-mouthed screw nuts
all arranged and operating substantially as herein described and shewn in the
drawings.
2. The arrangement of apparatus for coupling up to a water tap substantially as
shewn at Figs. 4 and 5 of the drawings.
3. In combination with the bulbous end part 6 of a coupling pipe such as a the

page_text: concentric groove and elastic ring has herein described and shewn at Fig. 5 of the
drawings.
Dated this 25th day of July 1896.
