PROVISIONAL SPECIFICATION left by the said Joseph Glover at the Office

JOSEPH GLOVER of Silcoates near Wakefield in the County of York "IMPROVE-
MENTS IN THE MANUFACTURE OF SOAP USED IN FULLING, MILLING AND SCOURING
WOOLLEN OR OTHER WOVEN OR FELTED FABRICS
"
According to my improvements in the manufacture of soap used in fulling
milling and scouring woollen or other woven or felted fabrics I employ rags, shivvy;
flocks, hair, mill waste containing wool or hair or other like fibrous materials
containing animal matter.
These I dissolve into a pulp by the application of caustic soda. or any other
strong caustic alkali after which water is added for the purpose of washing the
same, which precipitates the foreign matter..
The water containing the animal matter is now run off into another receptacle
and acid is added thereto which precipitates the animal matter. The water is
again run off, leaving the animal matter behind it after which caustic soda or other
alkali is added to re-dissolve the animal matter. It is then allowed to saponify
and after a few hours is ready for use.

the said Joseph Glover in the Great Seal Patent Office on the 20th March
1883.
Joseph Glover, of Silcoates near Wakefield in the County of York "IMPROVE-
MENTS IN THE MANUFACTURE OF SOAP USED IN FULLING, MILLING, AND SCOURING
WOOLLEN, OR OTHER WOVEN OR FELTED FABRICS.".
According to my improvements in the manufacture of soap used in fulling,
milling, and scouring woollen or other woven or felted fabrics, I employ rags,
shivvy, flocks, hair, mill waste containing wool or hair, or other like fibrous
materials containing animal matter.
.
These I dissolve into a pulp by the application of caustic soda or any other
strong caustic alkali after which water is added.
The proportions of the various materials used, and the mode of manufacturing
the soap are as follows:-
70
To 3 cwts of any of the following materials which may be used separately or in
combination;rags, shivvy, flocks, hair, mill waste containing wool or hair, or
other like fibrous materials containing animal matter-I use by preference.27 lbs
of strong caustic soda and 6 gallons of water. This reduces the animal matter or
material containing the animal matter to a pulp by boiling. When in tliis state
it is passed through sieves of various sizes, such sieves being placed by preference
one above the other, the one with the widest mesh being uppermost.
After the above process the material when cold is in a gelatinous state. It is
again put into the hot pan, and to it may be added tallow and a little soda ash,
also caustic soda for saponifying purposes, the quantity of these varying in
accordance with the required hardness of the soap.
The quality of the soap is greatly improved by being allowed to stand for two
or three weeks after being run into a soap frame of ordinary construction.
Having now described the nature of my said invention, I would have it
understood that I do not limit myself to the exact proportions above given, as the
same may be varied or modified to suit the nature of the material treated, and the
quality of the soap required; but what I do claim is :-
A soap manufactured from Rags, shivvy, flocks, bair, millwaste containing wool
or hair, or other like fibrous materials, containing animal matter substantially in
the manner and for the purposes herein set forth.
In Witness whereof, I, the said Joseph Glover, have hereunto set my hand and
seal this sixteenth day of March, in the year of Our Lord one thousand
