page_text: I EDWIN CHARLES HISCOX of 35 Edith Grove, Brompton in the County of
Middlesex Gentleman, do hereby declare the nature of this invention to be as
follows:
This invention has for its object a simple economical and effective apparatus
for connecting pipes for steam, gas, water and other fluids and also for the
expeditious stopping of leaks therein and consists essentially of a peculiar con-
struction of metal tourniquet which is employed in substitution for the wire
lapping hitherto used in the making of pipe joints for binding the two ends of a
rubber or other flexible length of tubing onto the contiguous ends of the pipes to
be joined together the said apparatus being also capable of being substituted for
solder or other stopping when repairing a leak in a pipe of any kind.
My improved tourniquet consists of a flexible metal spring which is of sufficient
length to pass entirely round the flexible tubing to be gripped thereby. On one
end of this spring there is fitted or formed a lug having a tapped hole therein a
corresponding lug having an untapped hole therein for the passage of the screw
being also fitted to or formed on the spring some distance back from the under-
lapping inner free end of the same. Through both these lugs there is inserted a
screwed pin provided with a convenient head for enabling it to be turned in order
to tighten the flexible spring round the flexible tube to any desired extent. By this
imeans it is obvious that the ends of the flexible tube enclosing the ends of the
pipes or tubes to be connected together can be firmly gripped or secured thereon by
a few turns of the screw in lieu of the long and tedious operation of lapping the
said ends thereby enabling a joint to be made or unmade in much less time than
by the usual method.
By applying a layer or packing of rubber or other suitable material to the
interior of the aforesaid flexible spring the same apparatus can be advantageously
employed for stopping leaks in metal or other tubes by being applied thereto direct
and tightened thereon.

'therein.
I EDWIN CHARLES HISCOX of 35 Edith Grove, Brompton in the County of
Middlesex Gentleman 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 has for its object a simple cheap and effective apparatus for
securing the flexible connections or couplings of pipes for steam, gas, water, and
other fluids applicable also for the expeditious stopping of leaks in pipes and
consists essentially of a peculiar tourniquet or screw clamp to be substituted for the
wire or other lapping hitherto used for securing or binding the two ends of a rubber
or other flexible length of tubing onto the contiguous ends of the pipes to be
flexibly connected together the same or a similar apparatus or screw clamp when
provided with suitable packing on its inner face being also applicable for stopping
leaks in pipes or tubes by being clamped directly thereon in substitution for the
use of solder or other stopping.
My improved tourniquet or clamp consists of a flexible strip of metal or other
suitable material or a spring curved so as to embrace the tubing or pipe to which it
is to be applied and of sufficient Jength to pass rather more than entirely round the
same. A lug or projection having a tapped hole therein is fitted to or formed on
one end of the said strip or spring for the thread of a tightening screw spindle to
work in. A second or corresponding lug or projection provided with an untapped
hole for the free rotation therein of the unscrewed portion of the screw spindle
fitted to or formed on the same flexible strip or spring at some distance back from
the opposite ends thereof which should underlap the outer end when fitted onto
the flexible tubing. Through both these lugs or projections there is passed a
screwed spindle engaging with the tapped hole in the one and turning freely in the
untapped hole of the other and provided if desired with an inner collar to prevent
it becoming detached from its holding lug or projection a convenient head or handle
being also provided for enabling the screw spindle to be turned for the purpose of
contracting the flexible strip or spring to any desired extent round the flexible tube
employed in making the connection or round the pipe itself when stopping a leak
therein as the case may be.
By this means it is obvious that the ends of the flexible tube enclosing the ends
of the pipes or tubes to be flexibly connected together can be more readily and
firmly gripped or secured thereon by a few turns of the screw in lieu of by the
long and tedious operation of binding or lapping the said ends thus enabling a
joint to be made or unmade in much less time than heretofore.
By applying a layer of packing of rubber, felt or other suitable material such as
Chatterton's Compound for example to the inner face of the flexible strip or spring
of the clamp which in that case need not have an underlapping end the same can

applied with its packing directly over the leak and tightened thereon in the manner
above set forth.

pipe-joint tourniquet or clamp detached.
Figure 2 is a corresponding edge view of the same.
Figure 3 is a part longitudinal section and part side elevation showing the mode
of applying the Tourniquet or clamp to the securing of the flexible tube employed
in making a flexible joint or coupling.
a is the flexible strip or spring. 6 the lug or projection fitted to or formed at one
end thereof, and provided with a tapped hole. c is the second or corresponding lug
or projection made with a plain or untapped hole and fitted to or formed on the
flexible strip or spring a at some distance back from the underlapping end a¹
thereof. d is the tightening spindle screwed at one end to engage with the tapped
hole in the lug or projection b, turning freely within the untapped hole in the lug
or projection c it being provided if found desirable with a collar e to prevent it from
becoming detached and mislaid and also with a head f for turning the same when
tightening or releasing the clamp. g g (figure 3) are the lengths of pipe to be
flexibly connected together. h is the rubber or other flexible tubing constituting
the connection between the pipes g. The contiguous ends of the pipes g may be
slightly expanded or enlarged at ii in order to obviate all risk of their being
drawn out of the enclosing flexible tubing.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In apparatus for securing the flexible connections or couplings of pipes for
stam, gas, water, and other fluids the combination of an underlapping flexible strip
or spring, lugs or projections fitted or formed thereon, and a tightening screw
passing through said lugs or projections substantially as specified and illustrated by
the drawings hereunto annexed.
2. In apparatus for stopping leaks in pipes for steam, gas, water and other fluids
the combination of a flexible strip or spring an inner lining of leather rubber or
other suitable packing, lugs or projections fitted or formed on the said flexible
strip or spring and a tightening screw passing through said lugs or projections
substantially as specified.
