Improvements in or relating to Couplings applicable for Connecting
or Uniting the Ends of Hose Pipes.
I, TOM SUTCLIFFE of 11, Brunswick Parade, Waterloo, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
The invention has for its object a coupling, applicable for uniting the ends of hose
pipes, or for uniting the ends of hose to an engine or nozzle.
To couple hose I employ a union or tubular connecting piece having a central collar
approximately equal in diameter to the diameter of the hose. The stems of said union
on each side of the collar (which are preferably provided with shallow grooves of
suitable shape or a roughened surface) are respectively made to receive the ends of
the two hose pipes, and each of these latter is secured to the union by a strap or
binding device.
The binding device comprises an elastic or flexible strap or band, one end of which
overlaps the other, and is turned up to form a projecting flange. The strap has
pivoted to it one end of a connecting piece or link preferably of variable length,
which may comprise a socket or sleeve into which is screwed, in line therewith, or
otherwise adjustably attached, a pin or stud. By rotating the said stud or socket the
length of the connecting piece may be changed; other equivalent arrangements may
however be employed. Partly surrounding or clasping the strap or otherwise arranged,
is a semicircular or other shaped clamping lever or plate, which is hinged to the other
end of the aforesaid connecting piece. One end abuts against the flange aforesaid,
and keeps the elastic strap compressed to a given diameter, so that the pipe is firmly
bound or clasped on the stem of the union. By turning the said lever or plate on its
hinge away from the strap, the pressure on the flange is removed and the strap
expands by virtue of its elasticity, so that the hose can be removed from the union.
To adjust the binding device so as to couple hose of larger or smaller diameters,
the end of the semicircular lever is released from the flange aforesaid, and the con-
necting piece is lengthened or shortened. The overlap of the flanged end of the strap
and the diameter of the strap will be found to have been increased or diminished
as the case may be when the device is again compressed on the periphery of
the hose.
.
The end of the connecting piece or link to which the clamping lever is hinged may
have a flat or square face to facilitate the said lever remaining either open or closed.
Suitable projections or depressions may be made to enable the lever to be easily
operated.
Another form of coupling comprises a flexible strap or band, one end of which
overlaps the other, and is turned up to form a projecting flange. Through a hole in
said flange a screw is passed adapted to engage a nut held or pivoted at a suitable
distance from the other end of said strap. By rotating the pin, the flange and nut
are caused to approach or recede, and thereby increase or decrease the diameter of
the strap and tighten the coupling on the hose pipe. The pin, if desired, may
have a winged head for manipulation by hand, or a head adapted for a screw-driven
spanner, etcetera.
To unite the ends of hose to a delivery nozzle or to the delivery orifice of an engine,
the hose is slipped onto the end of the nozzle which may have a grooved or roughened
surface similar to the union aforesaid. The clamping device can now be applied and
made to firmly unite the respective parts.

or Uniting the Ends of Hose Pipes.
I, TOM SUTCLIFFE of 11, Brunswick Parade, Waterloo, in the County of Lancaster,
Engineer, 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:--
The invention has for its object a coupling, applicable for uniting the ends of
hose pipes, or for uniting the ends of hose to an engine or nozzle.
The invention is best described by aid of the accompanying drawings, in which
Figure 1 is a section through the axis of a hose pipe, showing the arrangement for
coupling hose,
Figure 2 a side elevation of the coupling device,
Figure 3 an end elevation thereof,
Figure a screw adapted to be substituted for the winged screw shown in
Figures 2 and 3.
To couple hose, I employ a union or tubular connecting piece such as A, the outer
periphery of which is provided with shallow grooves of suitable shape or a roughened
or serrated surface. It is made to receive the ends of the two hose pipes, and
each of these latter is secured to the union by a strap or binding device.
The binding device comprises an elastic or flexible strap or band B, one end of which
overlaps the other, and is turned up to form a projecting flange b. The said strap B
has pivoted to it, one end of an adjusting screw C consisting of a socket or sleeve c
in which is screwed in line therewith a thumb screw c¹ passing through a hole in the
flange b. By rotating the thumb screw c', the flange b and socket c are caused to
approach or recede, according to the direction in which the screw c' is rotated, and
thereby decrease or increase the internal diameter of the elastic strap. By this
device the ends of the hose pipe can be firmly grasped on the union and a tight joint
formed. The thumb screw c¹ has wings to facilitate manipulation, or, if preferred, a
head adapted for a screw driver, spanner or the like.
To unite the ends of hose to a delivery nozzle or to the delivery orifice of an
engine or pump, the hose is slipped on to the end of the nozzle which may have a
grooved or roughened surface similar to the union aforesaid. The clamping device
can now be applied and made to firmly unite the respective parts.
In some cases I employ a duplicate coupling composed of two separate elastic straps
or bands secured together by one or more cross pieces. The straps are preferably
placed about inch apart, and can be operated quite independently of one another,
and their extreme width, when fastened together, is preferably about equal to the
length of the union. I prefer one of the straps to be operated by a slotted headed
screw and the other by a thumb screw, or locking arm.
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 :-
:-
1. In a coupling for uniting the ends of hose pipes or the end of a hose pipe to a
nozzle, or the like, an approximately annular elastic strap or band B of metal or
other hard strong material, one end of which overlaps the other, and is provided
with an adjusting screw connecting it with the other part of the strap and adapted to
adjust the internal diameter of the latter, whereby the ends of the hose can be com-
pressed and firmly grasped on a union or tubular socket or the like to form a tight
joint, substantially as described.

page_text: 2. The herein described arrangement of parts forming the coupling devices for
uniting the ends of hose pipes or the like, substantially as set forth.
