Obstructing the Draught.
I JAMES REID of 110 St. Georges Road Bolton in the County of Lancaster
Engineer do hereby declare the nature this invention to be as follows:-
My invention is for the purpose of stopping leaks in the tubes of Marine, Loco-
motive, or other similar tubular boilers, and at the same time accomplishing this,
without materially obstructing the draught through the tube I effect this object in the
following manner. 1 provide a tube about a foot or eighteen inches long, or any
convenient length, rather less in diameter than the boiler tube in which the loak
requires to be stopped. I slip a washer on each end of the tube, and retain them near
the ends of the tube by stops or collars, which prevent them approaching the middle
of the tube, but allow free motion towards the ends. Flanges are screwed on the
ends of the tube, and the diameters of the flanges and washers should nearly corre-
spond to the internal diameter of the boiler tube, so as to make an easy fit, when the
apparatus is slipped into the latter. I place an Asbestos, or other suitable packing,
between the flanges and loose washers, and the apparatus is then complète. Its
method of action is as follows.
When the above discribed apparatus is pushed along a boiler tube in which a leak
exists, as soon as the full extent of the leak is included between the washers and
packings at the opposite ends of the tube, the force of the escaping steam and water,
at once holds the apparatus in that position, forcibly drives the washers apart,
towards the ends of the tube, compreses and expands the packing and thus effectually
prevents the escape of steam or water. At the same time the draught through the
boiler tube has not been materially impeded.

JAMES REID 110 St. Georges Road Bolton Lancashire, 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:-
My invention is for the purpose of stopping leaks in the tubes of Marine, Loco-
motive, or other similar tubular boilers, and at the same time, accomplishing this
without materially obstructing the draught through the tube.
I effect this object in the following manner. I provide a tube about a foot or nine
inches long, or any convenient length, rather less in diameter than the boiler tube in which
the leak requires to he stopped. I slip a washer on each end of the tube and retain
them near the ends of the tube by stops or collars, which prevent them approaching
the middle of the tube but allow free motion towards the ends. Flanges are screwed
on the ends of the tube, and the diameters of the flanges and washers should nearly
correspond to the internal diameter of the boiler. tube, so as to make an easy fit, when
the apparatus is slipped into the latter. I place an asbestos or other suitable packing
between the flanges and loose washers, and the apparatus is then complete. Its
method of action is as follows.
When the above described apparatus is pushed along a boiler tube, in which a leak
exists, as soon as the full extent of the leak is included between the washers &
packings at the opposite ends of the tube, the force of the escaping steam and water,
at once holds the apparatus in that position, forcibly drives the washers apart
towards the ends of the tube, compresses and expands the packing, and thus effectually
prevents the escape of steam or water. At the same time the draught through the
boiler tube, has not been materially impeded.
Reference to the accompanying drawings will more clearly explain the nature of
my invention.

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:

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 principle, substantially as heroin dosoribed, of utilising the pressure of the
steam itself, escaping through the leak in a boiler tube, and acting within the space

page_text: contained between the boiler tube, the stopper, and the flanges at the opposite
extremities of the latter, in order to compress and expand a suitable packing, against
the terminal flanges of the stopper; thereby preventing the escape of steam from
the contained space, and consequently from the leak in the tube. I do not bind
myself to the exact details of the arrangement as described, but claim to employ such a
mechanical modifications for bringing the pressure of the steam to bear on the
packing, as the invention plainly susceptible of.
