IMPROVE- MENTS IN THE CONSTRUCTION OF APPARATUS FOR CUTTING AND MIXING OR COMPOUNDING SOAP AND OTHER MATERIALS
Year: 1878

page_text: LETTERS PATENT to William Wright, of Droylsden, and Thomas Bintliff, of
Manchester, both in the County of Lancaster, for the Invention of "IMPROVE-
MENTS IN THE CONSTRUCTION OF APPARATUS FOR CUTTING AND MIXING OR
COMPOUNDING SOAP AND OTHER MATERIALS,"
PROVISIONAL SPECIFICATION left by the said William Wright and Thomas
Bintliff at the Office of the Commissioners of Patents on the 17th September
1878.
WILLIAM WRIGHT, of Droylsden, and THOMAS BINTLIFF, of Manchester, both in
the County of Lancaster. "IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS
FOR CUTTING AND MIXING OR COMPOUNDING SOAP AND OTHER MATERIALS."
This Invention is designed principally for the purpose of cutting and mixing
or compounding hard soap with alkalies or other materials for the purpose of making
soap powder, but it is also equally applicable for cutting and mixing other materials
for other purposes.
In the process of making soap powder as usually practised, the soap requires to
be boiled, and the alkali or other materials being then thrown in, it is well stirred
and boiled together for some time; it is then allowed to cool and is afterwards
broken up into powder.
By the use of my improved apparatus no boiling is necessary, there is hence no
loss by evaporation, no chemical change takes place in the ingredients as they are
manufactured or compounded mechanically, and are not chemically combined, and a
great saving in time is effected.
The improved apparatus consists chiefly of a barrel or cylinder mounted or fixed
horizontally, or in other convenient position.

page_text: Through the centre of this passes a shaft capable of revolving in suitable bearings
and driven by means of an endless strap or otherwise, and making about one
hundred revolutions per minute.
On this shaft are mounted a series of knives projecting radially therefrom, and
arranged spirally or otherwise thereon.
Above the barrel is an opening fitted with a hopper for introducing the soap,
alkali, or other materials to be cut and mixed; and beneath the barrel is a second
opening for removing or discharging the contents. This discharge opening is fitted
with a door opening downwards and closed by means of a treadle.
The shaft with its knives' being in continuous motion, the attendant places his
foot on the treadle, and thus closes the discharge opening. He now fills in the soap
and alkali or other material, and when the same has been sufficiently cut or
disintegrated and well mixed or compounded together he removes his foot from
the treadle and the contents of the barrel are immediately discharged. He then
replaces his foot on the treadle and proceeds as before.

WILLIAM WRIGHT, of Droylsden, and THOMAS BINTLIFF, of Manchester, both in
the County of Lancaster, 'IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS
FOR CUTTING AND MIXING OR COMPOUNDING SOAP AND OTHER MATERIALS."
This Invention is designed principally for the purpose of cutting and mixing or
compounding hard soap with alkalies or other materials for the purpose of making
soap powder, but it is also equally applicable for cutting and mixing other materials
for other purposes.
In the process of making soap powder as usually practised, the soap requires to
be boiled, and the alkali or other materials being then thrown in, it is well stirred
and boiled together for some time; it is then allowed to cool and is afterwards
broken up into powder.
By the use of our improved apparatus no boiling is necessary, there is hence no
loss by evaporation, no chemical change takes place in the ingredients, as they are
mixed or compounded mechanically and are not chemically combined, and a great
saving in time is effected.
Such being the nature and object of our said Invention, we will now proceed to
describe in detail the manner in which the same is to be or may be performed
or carried into practical effect; and in order that the same may be clearly under-
stood, we have annexed hereunto a Sheet of Drawings illustrative thereof, and
have marked the same with figures and letters of reference corresponding with
those in the following explanation thereof:-
Fig. 1 in the annexed Drawing is a longitudinal section; and Fig. 2, a transverse
section of our improved machine for cutting and mixing or compounding soap and
other materials.
The improved apparatus consists chiefly of a barrel or cylinder a, a, mounted or
fixed horizontally or in other convenient position in a frame b, b.
Through the centre of this passes a shaft c, c, capable of revolving in suitable
bearings d, d, and driven by means of an endless strap or otherwise, and making
about one hundred revolutions per minute. On this shaft c, c, are mounted a series
of knives e, e, projecting radially therefrom and arranged spirally or otherwise
thereon. Above the barrel a, a, is an opening fitted with a hopper ff, for introducing
the soap, alkali, or other materials to be cut and mixed, and beneath the barrel
is a second opening for removing or discharging the contents. This discharge
opening is fitted with a door g, g, opening downwards and closed by means of a
treadle h, h.
The shaft c, c, with its knives e, e, being in continuous motion, the attendant
places his foot on the treadle h, h, and thus closes the discharge opening. He now
fills in the soap and alkali or other material, and when the same has been sufficiently
cut or disintegrated and well mixed or compounded together he removes his foot
from the treadle h, h, and the contents of the barrel a, a, are immediately discharged.
He then replaces his foot on the treadle h, h, and proceeds as before.
Having now described the nature and object of our said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, we wish it to be understood that we claim as our Invention the novel
construction of apparatus for such purpose as herein-before particularly described

page_text: and illustrated by the Drawing annexed, or any mere imitation or modification
thereof, constructed and operating in substantially the same or a similar manner.
In witness whereof, we, the said William Wright and Thomas Bintliff, have
hereunto set our hands and seals, this Fourteenth day of March, in the
year of our Lord One thousand eight hundred and seventy-nine.
