A NEW OR IMPROVED COMPOSITION FOR PREVENTING INCRUSTATION IN STEAM BOILERS, PIPES, TANKS, AND OTHER HOT WATER APPARATUS
Year: 1876

page_text: LETTERS PATENT to William Murdoch, Henry Horatio Ault, & William
Knowles, all of the Firm of Murdoch & Co., of 202, New Crane, Wapping,
in the County of Middlesex, for the Invention of "A NEW OR IMPROVED
COMPOSITION FOR PREVENTING INCRUSTATION IN STEAM BOILERS, PIPES,
TANKS, AND OTHER HOT WATER APPARATUS."
ealed the 25th July 1876, and dated the 27th January 1876.
PROVISIONAL SPECIFICATION left by the said William Murdoch, Henry
Horatio Ault, and William Knowles at the Office of the Commissioners of
Patents on the 27th January 1876.
WILLIAM MURDOCH, HENRY HORATIO AULT, & WILLIAM KNOWLES, all of the
Firm of Murdoch and Co., of 202, New Crane, Wapping, in the County of Middlesex.
* A NEW OR IMPROVED COMPOSITION FOR PREVENTING INCRUSTATION IN STEAM
BOILERS, PIPES, TANKS, AND OTHER HOT WATER APPARATUS."
This Invention has for its object the removal or prevention of incrustation in
steam boilers, pipes, tubes, tanks, and other hot water apparatus, by means of a
composition consisting of about equal parts of sand and sawdust combined with
ground glass, mica, and a small proportion of horse manure. These materials are
well mixed together, and are for convenience made up into cartridges or packets
about nine inches long and an inch and a quarter in diameter,, ready for being
introduced into boilers, tubes, tanks, or other hot water apparatus, coated with
scurf or liable to become incrusted with impurities.
This new or improved composition does not act chemically but exerts a
mechanical action uniformly and effectually, by circulating throughout the interior
of the boiler tubes, pipes, tanks, and other hot water apparatus, whether stationary,
locomotive, marine, or otherwise, thereby removing or preventing the formation of
scurf or other deposits upon the surface of the plates or tubes exposed to the action
of the hot water. By this means a great saving is effected in wear and tear, caused
by the removal of scurf and deposits by chipping or otherwise. Labour and expense
is also saved by rendering it unnecessary to take out the tubes of locomotive and
other boilers for cleaning, leakage from this cause being also prevented. Thus, by
preventing the boiler plates and tubes from becoming foul a great saving in fuel is
effected.

This Invention has for its object the removal or prevention of incrustation in
steam boilers, pipes, tubes, tanks, and other hot water apparatus, by means of a
new composition, consisting of equal parts of sand and sawdust, combined with
ground glass, mica, and a small proportion of horse manure.
These materials are

about nine inches long and an inch and a quarter in diameter, ready for being
introduced into boilers, tubes, tanks, or other hot water apparatus, coated with
scurf or liable to become incrusted with impurities.
This new
or improved composition does not act chemically but exerts a
mechanical action, uniformly and effectually, by circulating throughout the interior
of the boiler tubes, pipes, tanks, and other hot water apparatus, whether stationary,
locomotive, marine, or otherwise, thereby removing or preventing the formation of
scurf or other deposits upon the surface of the plates or tubes exposed to the action
of the hot water. By this means a great saving is effected in wear and tear caused
by the removal of scurf and deposits by chipping or otherwise. Labour and
expense is also saved by rendering it unnecessary to take out the tubes of loco-
motive and other boilers for cleaning, leakage from this cause being also prevented.
Thus by preventing the boiler plates and. tubes from becoming foul a great saving
in fuel is effected.
Having now described the nature of our said Invention, and the manner in which
the same is to be carried into effect, we would have it understood, that what we
claim and desire to have secured to us is the composition prepared as herein
described.
