Hose together or to Bib-taps or other Connections.
Year: 1886

page_text: Hose together or to Bib-taps or other Connections.
I CHARLES DARRAH, Junior of Holly Point, Heaton Mersey, in the County of
Lancaster, Salesman, do hereby declare the nature of my invention to be as
follows:-
In order to connect lengths of flexible hose together I employ a metallic ferrule,
the extremities of which are bulged outward to a larger diameter and then
gradually diminish in a conical form down to the ordinary diameter. Over these
bulges I force the respective ends of the lengths of tubing to be connected
together, and in order to secure the same in position I draw back upon the outside
of the tubing a metallic ring (which has been previously mounted upon the ferrule)
which thus tightens itself upon the expanded hose pipe and so effectually prevents
the same being withdrawn from the ferrule no matter what pressure is exerted by
the fluid passing through.
It will be apparent that, by having a similar bulge or cone formed upon or
affixed at the extremity of a bib-tap or hose connection of any description and
providing the same with a similar metallic ring as aforesaid, that a hose pipe could
be readily and effectually secured thereto, without the usual screw thread and
union joint.

page_text: Hose together or to Bib-taps or other Connections.
I CHARLES DARRAH, Junior, of Holly Point, Heaton Mersey in the County of
Lancaster, Salesman, do hereby declare the nature of my invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :--
On the accompanying drawing Fig. 1. represents an exterior view of my
improved coupling apparatus applicable to connecting two lengths of hose pipe or
tubing together, and Fig. 2. is a sectional view of Fig. 1. but shewing one length
of hose removed.
In carrying out my invention I employ a metallic ferrule a, the extremities b. of
which are bulged outwards to a larger diameter and then gradually diminish in a
conical form down to the ordinary diameter. Over these bulges b. I force the
respective ends of the lengths of hose pipe or tubing c. which are to be connected
together and then in order to secure the same in position I draw back upon the
outside of the hose pipe or tubing a metallic ring d. (which has been previously
mounted upon the ferrule a.) which thus tightens itself upon the expanded hose
pipe or tubing and so effectually prevents the same being withdrawn from the
ferrule, no matter what pressure is exerted by the fluid passing through.
I prefer to screw the ferrule a. together in two parts as illustrated in Fig. 2. and
then when the rings d. have been placed upon their respective parts, to soft-solder
the joint and thus prevent its becoming unscrewed. In this way I prevent the
rings d. becoming lost or removed from the ferrule, the smaller extremities e. of
the said rings being unable to pass over the bulges b.
It will be apparent that by having a similar bulge or cone formed upon or
affixed at the extremity of a bib-tap or hose connection of any description and
providing the same with a similar metallic ring as aforesaid, a hose pipe or other
flexible tube could be readily and effectually secured thereto without the usual
screw-thread and union joint.
Having thus particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
1st The improved construction of coupling apparatus substantially as and for the
purposes bereinbefore described.
2nd In the construction of coupling apparatus for connecting hose pipes or other
'flexible tubes together or to bib-taps or other connections, the employment of a
ring or rings in combination with a ferrule or its equivalent with bulged
extremities substantially as and for the purposes herein before described aud
illustrated on the accompanying drawing.
