PROVISIONAL SPECIFICATION.
An Improved and Simplified Coupling or Attachment for Hose,
Pipes, Tubes, and the like.
I JOSEPH EUGSTER of 2 Gresham Buildings Guildhall in the City of London
Merchant do hereby declare the nature of this invention to be as follows:-
My invention pertains to any sort of hose piping or tubing that requires to be
joined together or attached to a fixture such as various lengths of fire hose that it
is necessary to couple & make as one & that needs to be attached at the end to a
hydrant or connection of a similar nature.
Instead of screwing the lengths of hose or tubing together in the ordinary way
by means of a metal union with threads cut therein to form a screw & fastened to
each end of the hose which has the disadvantages of having to turn round the
whole length of the hose as many times as there are threads in the metal union to
couple it & results in the hose or tubing becoming twisted and entangled & is also
a cumbrous operation.
I propose to make this connection or attachment with a metal clamp or clasp
which will be constructed & act in the following way. In the case of hose each
length is fitted with an iron, brass copper, or gunmetal connecting piece so grooved
as to fasten to the hose in the ordinary manner by being bound thereto with wire
& made with a flange at the extreme end, said flange to be flat on the upper surface
and slanting on the under surface, in addition to the flange, each alternate con-
nection would have a small rim projecting that will pass or fit into the corresponding
connection piece & around this rim a washer of leather, india rubber or elastic
material will lay for the purpose of binding or sealing the joint. The two lengths of
hose so fitted are now placed together end to end, the clamp is laid round the metal
connection, clasping the two flanges & tightened up by means of the thumbscrew
therein. The clamp being composed of two movable jaws hinged, a tightening
piece & thumbscrew: round the inside is a cavity cut in a ▼ shape, the whole
being made of any suitable metal such as iron, tin, copper, brass or gunmetal. The
action of the clamp being this; as the same is tightened or closed by means of the
thumbscrew the inclined planes or slanting faces of the clamp are brought to bear
upon the corresponding planes of the flanges on the connecting pieces & with the
aid of the india rubber between, a water, gas or air tight joint is obtained a similar
result is also obtained, when the hose is required to be attached to a fixture as a
hydrant or the like, which would be fitted with a connection constructed on the
same principle as one of the corresponding pieces with flange, on the hose-greater
speed & facility in coupling & attaching is obtained with a perfect hermetically
sealed joint.

I, JOSEPH EUGSTER of 2 Gresham Buildings, Guildhall, in the City of London,
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 :-
My invention has for its object a simple and effective device for coupling
together hose, pipes, tubes, and the like.
1 attain this object by means of the mechanism illustrated in the accompanying
drawings in which Figures 1, 2, are plan views shewing the coupling closed and
open Figure 3 is a vertical section thereof when closed and Figures 4 and 5 are
detail sectional views of the nozzles hereafter referred to.
Similar letters of reference indicate corresponding parts in all the figures.
My invention consists of a clamp or clasp composed of two movable jaws a, a
pivoted or hinged together as shewn at band provided with a tightening piece c,
and thumb screw d whereby they can be tightened up when closed. The inner
surfaces of such jaws have grooves e, e', formed therein which are provided with
bevelled lateral faces e while the two ends of each length of hose, pipe, or tube
are fitted with nozzles f, furnished with collars f which have their upper edges
bevelled off as shewn at 2 to form corresponding faces to those formed on the
inner surfaces of the jaws, so that when the latter are placed over the nozzles and
tightened up, such bevelled surfaces are brought into contact with each other and
fit closely together.
The face of one of such collars is rebated as shewn at f³ Figure 4 to form a
seating for an elastic packing g which is fitted therein as shewn and is provided
with an extension piece h that takes into a socket (i Figure 5) formed to receive it
in one of the nozzles fitted to the succeeding length of hose, pipe, or tube, while
projecting from the face of such last mentioned nozzle is a threaded rimj Fig. 5
which when such two faces are brought together and tightened up by means of the
clamp or clasp as above mentioned presses against and takes into the elastic
packing and so hermetically seals the joint. A similar result is obtained when the
hose, pipe, or tube is attached to a hydrant or the like, provided that the latter or
its equivalent is fitted with a nozzle furnished with a bevelled collar and is other-
wise constructed in a corresponding manner to that herein before described. The
clamp or clasp may either be separate from or attached to the nozzles by means
of lugs and a pin as shewn in the accompanying drawings or in any other
convenient manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
I claim is;
As an improved and simplified coupling or attachment for hose, pipes, tubes, and
the like, a clamp or clasp consisting of two movable jaws pivoted or hinged
together and having grooved internal surfaces provided with bevelled lateral faces
that fit over corresponding flanges formed on the nozzles fitted to the various
lengths of hose, pipe, or tube and to the hydrants or their equivalents whereto such
hose, pipe, or tube is attached, all substantially as hereinbefore described and shewn.
