MEDICATED SALT BRICK.
SFECIFICATION forming part of Letters Patent No. 721,633, dated February 24, 1903.
Application filed June 12,1902, Serial No, 111,410. (No specimens.)To all wzhom it may concern:
Be it known that I, JAMES B. EATON, a citi-
zen of the United States, residing at Center-
point, in the county of Kerr and State of
5 Texas, have invented new and useful Iu-
provements in Medicated Bricks for Live
Stock, of which the following is a specifica-
tion.
This invention relates to medicated bricks
[o for live stock, and has for its object' to pro-
vide an improved brick of the character re-
ferred to by means of which, while the stock
obtain the necessary amount of salt to satisfy
their natural craving, is also administered a
[5 medicinal preparation which operates to pu-
rify the blood, regulate all stomach troubles,
cause a healthy action of the skin, expel
worms from the stomach and intestines, and
create a normal and healthy appetite.
20 Medicated salt rock intended to accomplish
the objects above set forth has heretofore
,been in use. Such medicated salt rock was
compounded of salt, cement, nitrate of pot-.
ash, santonin, nux vomica, gentian, sulfate
25 of iron, and sulfur. In making such salt
rock the cement was mixed with a sufficient
quantity of water to form a plastic mass, into
which the other ingredients were stirred to
produce a compound to harden into rock
30 form, the cement being employed as a binder
or adhesive agent. The compound was then
put up in the form of blocks or cakes of suit-
able dimensions and was designed to be
placed in the feed-boxes of the stock or places
35 where the animals have been accustomed to
be "salted." - The. cement used in the de-
scribed medicated salt rock was of no benefit
to the stock and was merely used as a binder
for the other ingredients, and a great deal of
40 water was required in mixing the salt and
medicine with the cement, and after mixing
the compound was placed in a wooden box
and left to dry, during which operation the
water came to the top, naturally carrying
45 with it the medicine, leaving the cement at
the bottom of the box, whereby after the rock
had become hardened the bottom of the block
was practically useless, only the upper side
thereof containing the medicine. Further-
50 more, with such composition the cement
hardened in the course of a few weeks to suchan extent that it would honeycomb when
licked by the stock and would soon become
so hard that the stock would be forced to bite
or crush it with their teeth rather than lick 55
it, as intended.
According to my present invention the for-
mula used for my improved medicated brick
is as follows: Liverpool evaporated salt, sixty-
five pounds eight ounces; clay, (such as here- 60
inafter described,) thirty pounds; sulfur, two
pounds; saltpeter, one pound; copperas, one
pound; nux vomica, (powdered,) six ounces;
santonin, two ounces.
The clay is mixed with water, and the other 65
ingredients are stirred in with the clay and
intimately mixed therewith. The mixture is
then molded into shape and placed in a press
and given approximately four thousand five
hundred pounds pressure to each brick. The 70
bricks are then placed in a dry-kiln and kept
there, say, for about forty-eight hours and
are then ready for use.
The clay employed for the purpose is found
in the immediate vicinity of Bainbridge, in 75
the county of Decatur and State of Georgia,
and is known in that vicinity as "Indian
pipe-clay." An analysis of this clay discloses
the presence of aluminium, iron, silica, mag-
nesia, lime, and traces of potash. This clay 8o
contains no gravel, grit, or grain of any kind
and requires only six quarts of water to mix
thirty pounds of it to form one hundred
pounds of the compound. By employing this
clay instead of the cement, as set forth in 85
the Letters Patent heretofore referred to, the
medicine is distributed evenly throughout
the entire brick. While the cement used in
the said former patent is of no benefit to the
stock, being simply employed as a binder, go
the clay referred to in the present invention
has been found in practice to be of a decided
benefit to the stock.
The bricks formed of my improved com-
pound herein described never become harder 95
than when taken from the kiln, will always
yield to the moisture of the animal's tongue,
and atmospheric changes have no effect what-
soever upon it. By means of my improved
brick the animal gets the medicine and salt co
in the exact proportions that is most bene-
ficial for it. The brick is to be used as a
