PROVISIONAL SPECIFICATION.
Improvements in Leak Stoppers applicable to Gas, Steam, and
Water Tubing.
I, FREDERICK DYE, of 30, Lewin Road, Streatham, in the County of Surrey,
Engineer, do hereby declare the nature of this invention to be as follows:-
This device is a "leak-stopper" to stop leaks in iron tubeswork such as is
erected for hot water, steam, cold water, gas, etc. With all these works the leaks
which are discovered (only too frequently) are where the tube screws into a
socket or fitting and this necessitates taking down part of the work which is
expensive and commonly very annoying to the customer. If a "back nut" (a
screwed collar) could be got on the pipe, it could, with proper packing material,
be made to stop the leak without taking the work down and it would be a per-
fectly legitimate way of stopping a leak, in fact a back-nut is a leak-stopper but
it cannot be got on the pipe after the pipe is fixed up.
My invention is a back-nut in two halves with lugs of any shape having holes
for the purpose of bolting or screwing the two halves together.
The use of a pair of half back-nuts with suitable means of securing them
together is the object of my invention.
In addition to the above, the threaded interior of the device is taper or bevelled
and by which means the nut will engage on a single thread if necessary. As a
rule only two or three threads of the tube are exposed outside the fitting, and
a bevelled thread as above described is necessary to the device to make it success-
ful under all conditions.

I, FREDERICK DYE, of 30, Lewin Road, Streatham, in the County of Surrey,
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:-
This device is a "leak-stopper" to stop leaks

which are discovered (only too frequently) are
in iron tube work such as is
With all these works the leaks
where the tube screws into a

expensive and commonly very annoying to the customer. If a
"back nut" (a

be made to stop the leak without taking the work down and it would be a per-
fectly legitimate way of stopping a leak, in fact a back-nut is a leak-stopper but
it cannot be got on the pipe after the pipe is fixed up.
My invention as illustrated in the accompanying drawing is a back nut in
two halves a and b with lugs d of any shape having holes for the purpose of
bolting or screwing the two halves together by means of screws e and nuts f.
The use of a pair of half back-nuts with suitable means of securing them
together is the object of my invention.
In addition to the above, the threaded interior c of the device is taper or
bevelled and by which means the nut will engage on a single thread if necessary.
As a rule only two or three threads of the tube are exposed outside the fitting,
and a bevelled thread as above described is necessary to the device to make it
successful under all conditions.
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
1 claim is:
A leak stopper applicable to gas, steam and water tubing, the combination
and arrangement substantially as above described in this specification and illus-
trated in the accompanying drawing.
