BENJAMIN JAMES CHRISTIE, HUGH KELLY JOSEPH FRAZER, SAMUEL
MCMILLEN and FRANK RUNDELL-Christie and Frazer work on this Patent in
the U.S. of America, Kelly and McMillen are Grocers and Rundell a Miner all
at Leadville Lake County State of Colorado U.S.A. do hereby declare the nature
of this invention to be as follows:-
A composition of matter to be used for covering steam pipes, boilers T joints,
elbows, valves, domes of boilers and other vessels for generating, holding, or
carrying steam to prevent the escape or waste of heat, which composition consists
of water, cotton-dust or refuse from cotton mills, fire clay, sawdust, plaster of paris,
alum, flaxseed, and rusty water in the proportions specified below.
The composition of matter consists of the above mentioned ingredients combined
in the proportions and applied as follows.
The first application" as it is called, consists of fire clay, five pints; plaster
of paris five pints; cotton-dust, (refuse and waste from cotton mills) one pound;
one gallon of rusty water, one fourth pound of alum, and one fourth pound of
flaxseed boiled together one half hour, one pint; pure water sufficient to make a
thin mortar of above ingredients.
The second application consists of plaster of paris, one fourth pound; fire clay
one fourth pound; cotton dust one pound; pure water sufficient to make a mortar
of the ingredients in this second application.
The third application consists of fire clay four pounds; cotton dust, one pound,
sawdust one half pound; pure water sufficient to make a mortar of the ingredients
in this third application.
The fourth application which is also the last, consists of cotton dust, one pound;
plaster of paris four pounds, these two ingredients to be mixed with one pint of the
composition described in the first application above-to wit one gallon of rusty
water one fourth pound of alum and one fourth pound of flaxseed boiled together
one half hour; pure water sufficient to make a mortar of the ingredients in this
fourth application.
The first application above described is to be applied to the pipe or other steam
boiler or chest with a brush or broom and is for the purpose of making the pipe
rough so that the succeeding applications as above given may adhere firmly to the
pipe so prepared.
The second application is applied about a quarter of an inch thick over the first
and after the first one has been allowed to dry thoroughly.
The third application is put over the second with a trowel and if an extra
thickness of the covering is required this application may be repeated as often as
desired.
The fourth application as all the others is mixed well together into a mortar for
the purpose of application to the pipes boilers &c. The fourth application is then
polished with brush and trowel and then painted with asphaltum.
In using the above described composition the pipes boilers and other vessels for
generating or holding and carrying steam should first be freed from all grease and
dirt which can be done by washing them thoroughly with a briue made of salt and
rusty water. The rusty water above mentioned is simply water in which iron has
been allowed to rust until it has colored the water.
By the use of the above composition the heat is prevented from escaping from
the steam through the pipes or boilers and through pipes so covered with the

page_text: composition as described above steam may be conveyed to a distance and kept at
a certain pressure with less consumption of fuel than would be necessary without
the said covering. The composition is fire proof and is a non-conductor of heat.

BENJAMIN JAMES CHRISTIE, HUGH KELLY, JOSEPH FRAZER, SAMUEL
MCMILLEN, and FRANK RUNDELL-Christie and Frazer work on this Patent in
the U.S of America Kelly and McMillen are Grocers and Rundell a Miner all
át Leadville, Lake County, State of Colorado, U.S.A. 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 invention consists of a composition of matter and a specific and special
mode of applying the same for covering, steam pipes, boilers, T joints, elbows,
valves, domes of boilers and other vessels for generating holding and carrying
steam to prevent the escape or waste of heat, which composition consists of, water,
cotton dust, or refuse from cotton mills fire clay, sawdust, plaster of paris alum,
flax seed and rusty water in the proportions specified below.
The composition of matter consists of the above mentioned ingredients combined
in the proportions and applied as follows;
The first application as it is called consists of fire-clay five pints, plaster of paris,
five pints; cotton dust, (refuse and waste from cotton mills) one pound; one
gallon of rusty-water; one fourth pound of alum; and one fourth pound of flax
seed boiled together one half hour, one pint of pure water sufficient to make a
thin mortar of above ingredients.
The second application consists of plaster of paris, one fourth pound; fire-clay,
one fourth pound; cotton dust, one pound; pure water sufficient to make a mortar
of the ingredients in this second application.
The third application consists of, fire-clay, four pounds; cotton dust, one pound;
sawdust, one half pound; pure water sufficient to make a mortar of the ingredients
in this third application.
The fourth application, which is also the last, consists of cotton-dust, one pound;
plaster of paris, four pounds; these two ingredients to be mixed with one pint of
the composition described in the first application above, to wit; one gallon of rusty
water; one fourth pound of alum, one fourth pound of flax seed, boiled together
one half hour, pure water sufficient to make a mortar of the ingredients in this
fourth application.
The first application above described is to be applied to the pipe, or other steam
boiler, or chest, with a brush or broom, and is for the purpose of making the pipe
rough, so that the succeeding applications as above given may adhere firmly to the
pipe so prepared.
The second application is applied about a quarter of an inch thick over the first
and after the first one has been allowed to dry thoroughly.
The third application is put over the second with a trowel, and if an extra
thickness of the covering is required this application may be repeated as often as
desired.
The fourth application, as all the others, is mixed well together into a mortar for
the purpose of application to the pipes, boilers, and the like. The fourth
application is then polished with brush and trowel, and then painted with
asphaltum.
In using the above described composition the pipes, boilers, and other vessels for

page_text: generating, or holding and carrying steam should first be freed from all grease and
dirt, which can be done by washing them thoroughly with a brine made of salt and
rusty water. The rusty water above mentioned is simply water in which iron has
been allowed to rust until it has colored the water.
By the use of the above composition the heat is prevented from escaping from
the steam through the pipes, or boilers, and through pipes so covered with the
composition as described above, steam may be conveyed to a distance and kept at a
certain pressure with less consumption of fuel than would be necessary without the
said covering. The composition is fire proof and is a non-conductor of heat.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
That we have invented a new and useful composition of matter along with a
specific and special manner of applying the same for covering steam pipes, boilers,
Tjoints, elbows, valves, domes of boilers, and other vessels for generating,
holding, and carrying steam, to prevent the escape or waste of heat; which
composition consists of water, cotton-dust or refuse from cotton mills, fire clay,
sawdust, plaster of paris, alum, flax seed, and rusty water, applied in the manner
and in the proportions specified above.
