UNITED STATES PATENT OFFICE,
N. C. RAYMOND, OF AUSTIN, TEXAS.
IMPROVEMENT IN COMPOSITIONS USED AS BUILDING MATERIALS,
Specification forming part of Letters Patent No. 21,775, dated October 12, 1858.
To all whom it may concern:
Be it known that I, N. C. RAYMOND, of the
city of Austin, in the county of Travis, in the
State of Texas, have discovered a new and use-
ful Composition of Matter for Building and
Fencing Purposes; and I do hereby declare
that the following is a full and exact descrip-
tion thereof.
The nature of my invention consists in the
production or formation of a material for build-
ing purposesin the shape of an unburned brick,
solid and durable, and possessing the power or
quality of being unaffected by rain as soon as
the drying process fairly begins.
To enable others to make and use the com-
position, I will proceed to describe it.
As the most applicable name, I have called
it LithocollaConcreta,"indurating stone-glue
or concrete-cement, formed by an application
of the following substances to the common
clays or soils of the country, to wit: of quick-
lime, twenty-eight (28) parts; of pulverized or
powdered charcoal, six (6) parts; of clay or soil,
(unburned,) forty-nine (49) parts;. of pasture.
fed-cow dung, powdered, seventeen (17) parts;
or of slaked lime, thirty-seven (37) parts; of pul-
verized or powdered charcoal, six (6) parts; of
clay or soil, (unburned,) fifty-seven (57) parts.
Mix to the consistence required for lnortar with
a strong solution of pasture-fed-cow dung. I
mold it into blocks of any required size, or use
it for building or fencing purposes, in the same
way that the common gravel or concrete wall is
built, or as a substitute for the common lime-
and-sand mortar. The cow-dung renders the
composition impervious to the action of any
ordinary rain as soon as the drying process
begins.
What I claim as my invention, and desire to
secure by Letters Patent, is-
The application of pasture-fed-cow dung, ei-
ther in substance or solution,together with lime,
either slaked or unslaked, or other powerful al-
kaline substance, and charcoal to the common
clays or soils of the country, for the purpose of
pIroducing a building material, substantially as
described.
N. C. RAYMOND.
