forming the hereinbefore referred to homoge-
neous mass of fibrous and gelatinous material
to permit of a mechanical separation by press-
ure of the two products thereof.
5 Having thus described our invention, what
we claim, and desire to secure by Letters Pat-
ent, is--
1. The process of preparing a lubricant, con-
sisting of the following steps: first, removing
to from the cactus - plant the thorns thereon;
second, reducing said plant by cutting or
cr-ushing into sections or pieces, and, third,
mixing the cacti so prepared with oil, all sub-
stantially as described.
15 2. The process of preparing alubricant from
the common cactus-plant and crude or refined
animal, vegetable, or mineral oil, consisting of
the following steps: first, removing from the
said plants the thorns thereon; second, reduc-
20 ing said plants by cutting or crushing into sec-
tions or pieces; third, placing the cacti so
processed as above in tubs or vats and allow-
ing it to there remain until it forms a substan-
tially homogeneous mass, and, fourth, mixing
25 such mass with oil, substantially as described,
and for the purpose set forth.
3. The process of obtaining a lubricant from
the common cactus-plant and animal, vegeta-
- ble, or mineral oil, consisting of the following
3) steps: first, removing from said plants the
thorns thereon; second, reducing said plant
by cutting or crushing into sections or pieces;
third, placing the same in tubs and allowing
it to remain until it forms a fibrous gelatinousmass, and, fourth, separating the gelatinous 35
and fibrous portions thereof and mixing such
gelatinous portion with an animal, vegetable,
or mineral oil, substantially as described.
4. The process of obtaining a lubricant from
the common cactus-plant and animal, vegeta- 4c
ble, or mineral oil, consisting of the following
steps: first, removing the thorns from said
cactus; second, reducing it by crushing or cut-
ting into sections or pieces; third, mixing the
said cacti so processed with crude or refined 45
animal, vegetable, or mineral oil, and, fourth,
of allowing the same to remain in tubs until
an oily, gelatinous, and fibrous mass is ob-
tained, and then removing said fibrous portion
therefrom by pressure, all substantially as de- 53
scribed.
5. As a new article of manufacture, a lubri-
cant consisting of a mixture of crude or re-
fined animal, vegetable, or mineral oil and a
gelatinous material obtained from the cactus- 55
plant, all substantially as described.
6. As a new article of manufacture, a lubri-
cant consisting of a mixture of crude or refined
animal, vegetable, or mineral oil and the
fibrous and gelatinous material obtained from 6o
