JOSEPH A. GREER, OF GALVESTON, TEXAS.
COMPOUND FOR THE MANUFACTURE OF ARTIFICIAL STONE.
SPECIFICATION forming part of Letters Patent No. 269,849, dated January 2, 188e.
- Applieatn Aled Jly 3, 18.1 (so apecimene .) 1 : -To all whkon it mnay concern :
Be it 4nown that I, JOSEPH A. GREE, of
the cliy aid cinlluty of Galveston, and State of
!exas, have invented -certain new and useful
5 Clnipoinlis for the Manufaceture of Artifiial
Stoie; and I do hereby declare the following
to be a full, clear, and exact description of the
invention, such as will enable others skilled in
the art to which itapjiertnins to make and use
to flie same.
This-invention relates to that class of com-
pontia used in the manufacture of artificial
stone; and it consists in composition formed
by mixing certain materials in solution and
rs treating them in further solutions, as follows:
Take one hundred (10l} poi bds of. hbdIrinli
ce tt four hundred (40) pounds oo larp
.i " twenty (20) pounds of powdered "mar
"iini~o Jitnestote, one (1) pound of pow dered
zo clharcolln e (1) lponnd of black oxide of man-
.es. 'Tlhen Inix these thorough luy y pass-
i11ng t through a coarse and then through
a fine sieve. Then make a solution of the fol-
l Iowingmaterials towit: thinrTfyto (3 gallons
S23 of water, three pounds of precipitate of car-
bonate of iron, one pound of Carbounte o
aussilnl, two pounds of sulatef aumnin
To pounds of ferric oxide and sixteen Oinces
oF :muriatic a cid. . , M roughlyand dampen
30 lh 1 bove-menionfc powder with it, using
grentcare not to make the pawder'too d tml.
About oine-eighth of the solhition will be thb
right proportion. I now tamp into molds of
desired tori. Whenr the stones ar' ihed
3y cut of the molds I moisten them threetimesa
day for five days w ff"i lution consisting of
"ite-foutrth potfnd of carbounte of potassium
i and two gallons of water. When the stones
Share dry * theai with the following solid:
40 tio; onie- Tf pbund of tallow. one-fourt
S potud of white wi one-fotrt' pound of -
-. bonate of p,,tassln, and two gallons of wa
S- ter.- 3 tsi solulon until the ingredietits
a e T dissolver and aRply hot. After
fr . 4( twenty-four hours coat with a solution com-
-' pound of bna gall"ff water ati oe-alf
pound ofsulphate of alumina. I twelve hoursthey are ready for use. Stone made in this
way is very denseatl impervious to waier, and
cann be cut with a ebisel, like ~liy other rock. go
For any desired col use ill the first-named
composition the mineral oxide currespouding
in -olor to tha\-desired. The last two named
suolanons Iyiav ye applied wfth a flat brusif.
\.WhatIclaim.as myinvention, and desireto $S
sedure' by L tters Patent. is-
1. As p basis or body for artificial stone, the
combination of ,the following elements, viz:
hydraulic cement, sharp sand, powdered mnag-.
inesial linestone, powdelore Ula tircoal,anl dblak:;6
oxide of manganese, in snbstantially-the pro-
portions spealied,, iith 'the liquid compound
or solutioil betein set forth.
2. The solution or liqid compound herein
described for moistening ianll tempering ce- 65
ments and comol)Mlils for atrtifluial stone, con.
sisting of caronate of iron, carbonate of po-
tassium, sulphate of aluminm, ferric oxide,
Inmriatic acid, and water in eubstaatiall the"
proportions set forth. 74
3. The solution herein described for water,
prqofing artificial gtoie, the same consisting of -
tallow, Wax, carbonate of potassium, and wa-
ter, treated in the marner described, and ap-
plied in substanutiafi the manner set forth.:
4. The solution herein described for harden-
ing artificial stoie, the same cotbsisting of
water and sulphate of alumina in the propor-
tions set forth.'
5. Tate method herein described of water- 8o
proofiig'and hardening artificial stone, the
saiite consisting in coating or saturating the
stone with compound of tallow. wax, harboir-
ate of potassium, and water, and after allow,
ing the stone to dry then subjetfing it tq a 85.
solution of sulphate of alumina, as set forth.
In testilmoti that I claim the foregoi, i
havrd hereunto set my hand this 25th'day of
