COMPLETE SPECIFICATION.
A New or Improved Union for Hose Pipes.
We, FELIX. LOUIS DECARIE Engineer of 29 St. Etienne Street, PETER LORD
Machinist of 31 Jacques Cartier Square, and JOHN LEE, Contractor, of 428 Cadieux
Streel, all of the City of Montreal, Canada, 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 :-
Our invention relates to a union for attaching two ends of hose together; or an end.
of hose to a coupling, and the chief object of our invention is to provide a ready and
secure means of repairing bursts of hose, and of attaching lengths of hose to fire
plugs or couplings, as we shall describe referring to the accompanying drawings, in
which similar letters of reference indicate like parts.
Fig. 1 is a longitudinal section on line a of Fig. 2 which is an elevation of a hose.
union accor.ling to our invention, and Fig. 3 is an end view of the sleeve a, detached.
Fig. 4 is an elevation of a half union for attaching to a plug or coupling.
a is a sleeve having about its middle a projecting flange b, made with notches c, to
which a hose-wrench can be applied for holding it. On each side of the flange b, the
sleeve is tapered to a larger diameter outwards and is made with a screw thead or
with corrugations or grooves d, the ends being of such size that they will fit within
the hose f.
e, are screw-threaded collars or nuts internally tapered from the face next the flange b,
to a larger diameter at the outer face. Each of these collars is of bore large enough
to pass freely over the end of the sleeve a, when there is no hose on it; and when it
is in the position of the upper collar in Figs. 1 and 2, there is space for the end of the
hose to be introduced between the collar and sleeve. When the end of the hose is
thus introduced, the collar e, is pushed and screwed outwards upon the hose until by
reason of the taper of e and a, the end of the hose is compressed into the screw-threads
and securely jammed as shown in the lower part of Fig. 1.
The collars e, are made with notches c, so that they can be turned by a hose
wrench.
As shewn in Fig. 4 the sleeve a may be made with a screw g, to connect to a fire-
plug or coupling, having the hose f and collar e applied only on the one side of the
flange b the single end having only one collar e, as shown in Fig. 4, and one taper, in.
all other respects it is made and operated as shown in Fig. 1, and as described.
Our invention is applicable with great advantage for repairing bursts of hose which
often occur at fires rendering whole lines of supply ineffective until the burst is
repaired. In such a case it is only necessary to cut out the burst part, and introduce
the union according to our invention, which can be done in a very short time, and the
hose is then rendered as effective as it was before the burst took place.
Owing to the arrangement of the tapers of the sleeve a and collars e, the greater
the pressure in the hose and therefore the greater the strain tending to pull the ends of
the hose off the sleeve, the more forcibly are the collars e drawn away from the flange b
clamping more tightly the ends of the hose, even in cases when they are insufficiently
tightened in the first instance.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
