PROVISIONAL SPECIFICATION.
Tube Stopper for Stopping Tubes Burst by External Pressure.
I, HENRY THOMAS BARRON SANDERSON of 8 Trajan Street South Shields in the
County of Durham Engineer do hereby declare the nature of this invention to be as
follows:-
The stopper consists of a rod of wrought iron screwed at both ends and with or
without joint in centre, one ends consists of a screwed ferrule with a collar attached
the same diameter as inside of tube, also a loose washer the same diameter of collar
and a square washer the side of which is equal to the outside of tube. Between the
loose washer and collar on ferrule is an india rubber washer, or any soft metallic
substance, the whole is tightened up with a nut on the ferrule.
The other end consists of two loose washers, same diameter as inside of tubes, with
holes drilled out of centre, so as nut on rod end will have a long side to it, or other-
wise to prevent it from turning round whilst screwing it up from front end. Between
the loose washers is an india rubber washer or some soft metallic substance.

I, HENRY THOMAS BARRON SANDERSON, 8 Trajan Street South Shields in the
County of Durham, 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 Apparatus consists of a Rod of Wrought Iron "A with or without a joint,
screwed at both ends with a larger diameter and square at the front end.
The Front end Stopper consists of a screwed Ferrule "B" with a Collar at the one
end, about the same diameter as inside of Tube; also a loose Washer "C" and Nut" I)"
screwed on the ferrule "B." Between the loose Washer "C" and Collar on Ferrule "B"
is placed a Washer "E" of India Rubber or any soft metallic substance.
The Back end Stopper consists of two loose eccentric Cones "F" about the
same diameter as inside of Tube, and an eccentric nut "G." Between the Cones "F"
is placed a Washer "H" of Indiarubber or any soft metallic substance.
The Back and Front end Stoppers are placed into the front end of Tube leaving the
Wrought Iron Rod "A" projecting out of the Tube. The front end Stopper is then
made steam tight by screwing up the nut "D" on Ferrule "B." The Back end
Stopper and rod is then pushed into the Tube to its proper position. The Back end
Stopper is then made steam tight by screwing on the square at the front end of
Wrought Iron Rod "A."
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
"The stopping of leaky Tubes burst by External Pressure by means of a single
Rod with or without a joint in it, and back and front Stoppers.
The Back and Front end Stoppers are so arranged that the Front end Stopper can be
made steam tight before the Back end Stopper is allowed to pass the fracture in the
Tube, thus preventing the steam & water scalding those engaged in the stopping of
the Tube.
The Front end Stopper forms a Stuffing Box for the Wrought Iron Rod "A" which
is projecting out of the Tube, until the front end Stopper is made steam tight.
The Back end Stopper consists of two eccentric Cones "F" and an eccentric
Nut "G." The eccentric nut "G" is screwed on to the Wrought Iron Rod "A."
The Stopper and Rod is then pushed past the fracture in Tube, and the back end
Stopper is made steam tight by screwing on the Square on the front end of Wrought
Iron Rod "A."
