MAX WINDSPERGER and ALBERT SCHAEDLER, of No. 28, Finsbury Square, in
the City of London, Gentlemen. "AN IMPROVED LIQUID OR COMPOSITION FOR
EXTINGUISHING AND PREVENTING FIRE."
I. Our liquid is composed of five different ingredients, which, when carefully
mixed according to our formula, will extinguish any fire in the shortest time, even
when used in a very small quantity, & has advantages in extinguishing fire
attained by no other such composition invented until now.
II. It may be used against any material which stands in fire, be it wood, coal,
wool, cotton, petroleum, fat, tar, benzoline, in short against any object the easiest
inflammable.
III. The liquid can be applied without the help of any apparatus, any vase at
hand will serve the purpose, but can also be applied most successfully with a fire-
engine.
IV. The liquid contains no acid.
V. When applied produces nor smoke nor vapeur.
VI. It will stand without freezing the lowest temperature.
VII. The quantity used for extinguishing fire in comparison to water is 1 : 10.
VIII. The liquid can be preserved for years.
IX. Objects besprickled with same regain their original appearance when washed
with cold water.
X. Objects extinguished with our liquid will not rekindle again as long as the
mixture remains in a damp condition on it.

page_text: XI. The cost-price of our liquid is very moderate, and can be purchased by every
class of people.
It is therefore our opinion that this our Invention will be of the greatest public
utility, especially to those who keep stores of dangerous materials, as well as
shipowners, warehouses, theatre-proprietors, etc., etc.
XII. The liquid is composed of the following ingredients:-
1.) 25 gallons of water.
2.) 15 lbs. common salt.
3.) 1 lb. alum in powder.
4.) 28 lb. silicate of sodium.
5.), lb. red chalk,
and is to be manufactured in the following way:-
A cask is filled up with No. 1, to which No. 2 is added, and immediately after
No. 3. These three ingredients mixed together are effectually stirred up and left
alone for two hours to dissolve themselves. After the lapse of two hours, No. 4 is
added by slow degrees and small quantities, during which the mixture must be
continually stirred up, and lastly No. 5 is added, and the liquid is ready for use.

the said Max Windsperger & Albert Schaedler in the Great Seal Patent
Office on the 14th April 1881.
MAX WINDSPERGER and ALBERT Schaedler, of No. 28, Finsbury Square, in
the City of London, Gentlemen. "AN IMPROVED LIQUID OR COMPOSITION FOR
EXTINGUISHING AND PREVENTING FIRE."
The liquid is composed of five ingredients mixed together according to the
formula hereinafter given, and will extinguish any fire in the shortest possible time,
and it possesses the following advantages
1. Fires produced by the most inflammable substances, such as straw, coal,
petroleum, and even benzoline may be extinguished instantaneously by the aid
of this liquid.
2. Fire extinguished by this solution will not rekindle, and so effectual is this
Invention, that a person may dip his hand into the liquid, and then place it in a
flame without sustaining any injury.
3. The liquid may be applied with any utensil at hand, or in any convenient
manner.
4. The liquid is free from acid, and therefore will not damage the utensil or
engine used for its application, nor the object it is applied to.
5. The liquids will bear any degree of cold without freezing.
6. A small quantity only of this liquid is required to extinguish a fire, as in
practice it is mixed with water in about the proportion of 1 to 10.
7. Various fabrics, materials, and articles may be rendered incombustible by
saturating or covering the same with the liquid.
8. The liquid may be preserved for years without losing its efficacy.
9. The liquid may be sold at a low price, thus rendering it accessible to all
classes.
The liquid or composition consists of the following ingredients in about the
proportions given, and combined in the manner stated :—
1. Twenty five gallons of water.
2. Fifteen pounds of common salt.
3. One and a quarter pounds of alum in powder.
4. Twenty eight pounds of silicate of sodium.
5. One quarter of a pound of red chalk.
In combining these ingredients, No. 1 is placed in a vessel, No. 2 is then added,
and immediately afterwards No. 3 is introduced.
These three ingredients thus mixed together are to be thoroughly stirred or
agitated, and then allowed to stand for about two hours, in order that they may
become dissolved.
After the solution has been effected, No. 4 is added by slow degrees and in small
quantities, during which the mixture must be continually stirred or agitated; and
lastly, No. 5 is added in a similar manner, after which the liquid is ready for the
market.
It will be understood that the proportions of the ingredients and the mode of
combining them may be varied without departing from the nature of the Invention.
Having thus described the nature of the said Invention, and the mode in which

combined in the manner stated.
