AN IMPROVED COMPOSITION FOR PREVENTING FREEZING IN THE CYLINDERS, AIR PASSAGES, AND EXHAUST PIPES OF ENGINES WORKED OR DRIVEN BY COMPRESSED AIR, ALSO OF OTHER ENGINES AND PUMPS, SUCH COMPOSITION BEING ALSO AP- PLICABLE FOR LUBRICATING THE SAME.

page_text: LETTERS PATENT to Edward Brown, of Normanton, and Joseph Rider, of
Leeds, both in the County of York, for the Invention of "AN IMPROVED
COMPOSITION FOR PREVENTING FREEZING IN THE CYLINDERS, AIR PASSAGES,
AND EXHAUST PIPES OF ENGINES WORKED OR DRIVEN BY COMPRESSED AIR,
ALSO OF OTHER ENGINES AND PUMPS, SUCH COMPOSITION BEING ALSO AP-
PLICABLE FOR LUBRICATING THE SAME.'

Sealed the 26th June 1877, and dated the 20th December 1876.
PROVISIONAL SPECIFICATION left by the said Edward Brown and Joseph
Rider at the Office of the Commissioners of Patents on the 29th December
1876.

EDWARD BROWN, of Normanton, and JOSEPH RIDER, of Leeds, both in the County
of York. AN IMPROVED COMPOSITION FOR PREVENTING FREEZING IN THE CYLIN-
DERS, AIR PASSAGES, AND EXHAUST PIPES OF ENGINES WORKED OR DRIVEN BY
COMPRESSED AIR, ALSO OF OTHER ENGINES AND PUMPS, SUCH COMPOSITION BEING
ALSO APPLICABLE FOR LUBRICATING THE SAME.
"
The great difficulty with engines driven or worked by compressed air has been
owing to the formation of ice in the cylinders, air passages, and exhaust pipes
caused by the atmospheric compression.
The object of our Invention is to overcome and prevent this formation, and to
provide at the same time a lubricant, and is as follows:-We prepare a strong solution
of salt and water, and with it we mix a quantity of black lead. When thoroughly
mixed the oil cups, or lubricators, on the cylinder or cylinders, and valves, or air
passages are filled with the composition in the saune manner as when oil or other
lubricant is used; the taps or cocks are left sufficiently open so as to allow a con-
tinuous trickling of the composition into the interior of the cylinder valves or air
passages; by this means not only is the formation of ice entirely prevented, but also
lubrication takes place without the use of oil or other lubricants.
By applying the composition to other engines or pumps freezing up of the same
is entirely prevented, and sufficient lubrication effected.

EDWARD BROWN, of Normanton, and JOSEPH RIDER, of Leeds, both in the County
of York. "AN IMPROVED COMPOSITION FOR PREVENTING FREEZING IN THE CYLIN-

The greatest difficulty with engines driven or worked by compressed air has been
owing to the formation of ice in the cylinder, air passages, and exhaust pipes caused
by the atmospheric compression and expansion.
The object of our Invention is to overcome and prevent this formation, and to
provide at the same time a lubricant, and is as follows:-We prepare a strong
solation of salt and water, and with it we mix a quantity of black lead in propor-
tions of say about to each gallon of water add two and a half pounds of salt and two
ounces of black lead. When thoroughly mixed the oil cups or lubricators on the
cylinder or cylinders, and valves, or air passages are filled with the composition in
the same manner as when oil or other lubricant is used, the taps or cocks are left
sufficiently open so as to allow a continuous trickling of the composition into the
interior of the cylinder, valves, or air passages; by this not only is the formation of
ice entirely prevented, but also lubrication takes place without the use of oil or
other lubricant..
By applying the composition to other engines or pumps freezing up of the same
is entirely prevented, and sufficient lubrication effected.
Having now described the nature of our said Invention, we would have it under-
stood that the quantities of the ingredients herein nained may be varied according to
circumstances without departing from the Invention, but what we desire to be
secured to us by Letters Patent is, the combination of the ingredients herein-before
described, forming a composition for preventing freezing in cylinders, air passages,
and exhaust pipes of engines worked by compressed air, and for lubricating the
same, substantially as herein set forth.
In witness whereof, we, tho said Edward Brown and Joseph Rider have
hereunto set our hands and seals, this Twenty-seventh day of June, in
the year of our Lord, One thousand eight hundred and seventy-seven.
