CERTAIN IMPROVED APPARATUS TO BE USED IN THE MANUFACTURE OF SOAP."
Year: 1862

page_text: LETTERS PATENT to William Gossage, of Widnes, in the County of
Lancaster, Chemist, for the Invention of "CERTAIN IMPROVED APPARATUS
TO BE USED IN THE MANUFACTURE OF SOAP."
PROVISIONAL SPECIFICATION left by the said 'William Gossage at the
Office of the Commissioners of Patents, with his Petition, on the 7th
May 1862.
I, WILLIAM GOSSAGE, of Widnes, in the County of Lancaster, Chemist,
do hereby declare the nature, of the said Invention for "CERTAIN IMPROVED
APPARATUS TO BE USED IN THE MANUFACTURE OF SOAP," to be as follows:-
My Invention of certain improved apparatus to be used in the manufacture
of soap applies to that portion of the said manufacture in which the alkaline
or saline solutions used in such manufacture require to be withdrawn from
the vessels or soap pans in which soap is being manufactured, also applies to
that portion of the manufacture in which it is required to transfer the perfect
or imperfect soap from such vessels or soap pans either into frames to solidify
by cooling or into other vessels in which the manufacture may be further
proceded with. In effecting the objects of my Invention, I provide a cover
to the vessel or soap pan in which soap is being manufactured which cover
may be in one or more pieces, and I adapt such cover to the said vessel or
soap pan so that the junction thereto may be air-tight, and thus convert the
said vessel or soap pan into a closed apparatus. I also adapt thereto one or

page_text: more pipes extending from above the cover of the said vessel or soap pan to
the lower part thereof and passing through the said cover, or through the side
of such vessel or soap pan, such pipe or pipes being so arranged that the
lower end (which is open) may be raised or lowered in the said vessel or soap
pan. I also provide a pipe which I attach by an air-tight joint to the upper
part of the said vessel or soap pan through which I can introduce high-pressure
steam or compressed air into the said vessel or soap pan which being so
introduced above the surface of the materials contained therein, occasions such
materials to be forced by hydrostatic pressure and become elevated through
the said pipe or pipes, and thus be transferred by compression from within
such vessel or soap pan and to be delivered through the upper end of such
pipe or pipes from whence the same may be conducted into soap frames or
other suitable receptacles.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Gossage in the Great Seal Patent Office on the
7th November 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GoSSAGE, of Widnes, in the County of Lancaster, Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing dato the Seventh day of May, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Gossage, Her special license, that I, the said William Gossage,
my executors, administrators, and assigns, or such others as I, the said
William Gossage, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
. use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "CERTAIN,
IMPROVED APPARATUS TO BE USED IN THE MANUFACTURE OF SOAP," upon the condition
(amongst others) that I, the said William Gossage, by an instrument in
writing under my hand and seal, should particularly describe and ascertain,
the nature of the said Invention, and in what, manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.

page_text: NOW KNOW YE, that I, the said William Gossage, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement reference being had to the Drawing hereunto annexed; and to the
letters and figures marked thereon (that is to say):-
My Invention of Certain Improved Apparatus to be used in the Manufacture
of Soap" applies to that portion of the said imanufacture in which the alkaline
or saline solutions used in such manufacture require to be withdrawn from the
vessels or soap pans in which soap is being manufactured also applies to that
portion of the manufacture in which it is required to transfer the perfect or
imperfect soap from such vessels or soap pans either into frames to solidify or
into other vessels in which the manufacture may be further proceeded with.
In effecting the objects of my Invention, I provide a cover to the vessel or
soap pan in which soap is being manufactured, which cover may be in one or
more pieces, and I adapt such cover to the said vessel or soap pan so that the
junction thereto may be air-tight or nearly air-tight, and I tlius convert the
said vessel or soap pan into a closed apparatus, I also adapt thereto one or
more pipes extending from above the cover of the said vessel or soap pan to
the lower part thereof and passing through the said cover, or through the side
of such vessel or soap pan, one of such pipes being so arranged that the lower
end (which has several openings into it) may be raised or lowered in the said
vessel or soap pan, I also provide a pipe which I attach by an air-tight joint
to the upper part of the said vessel or soap pan, through which I can introduce
high-pressure steam or compressed air into the said vessel or soap pan, which
being so introduced above the surface of the materials contained therein
occasions such materials to be forced by hydrostatic pressure and become
elevated through the said pipe or pipes and thus to be transferred by com-
pression from within such vessel or soap pan and to be delivered through the
upper end of such pipe or pipes from whence the same may be conducted
into soap frames or other suitable receptacles.
The Drawings hereunto annexed represent such an arrangement of apparatus
as I have found to be well adapted for effecting the objects of my Invention.
Fig. 1 is a plan view; Fig. 2 is a vertical section of the same; and Fig. 3 is
an enlarged view of a portion thereof.
In these Figures the same letters of reference are employed to indicate
similar parts. A is a soap pan or ordinary vessel used for the manufacture of
soap. B, B, is a lid or cover adapted to the same. The portion B*, is
attached permanently to the upper part of the soap pan. The portion B is
attached to B, by a hinge or joint C, by means of which it
may be elevated

page_text: so as to give access to the soap pan or lowered so as to rest on the upper
part of the soap pan. I provide a groove D all round the edge of the move-
able part B of the lid or cover, and into this groove I adapt a continuous ring
or rope of india-rubber E. I also adapt to the upper part of the soap pan, and
to the fixed portion B, of the lid or cover an angle piece of iron so shaped as
to form a bearing, on which the moveable portion B of the lid may rest when
it is lowered down on to the soap pan, and between which and such moveable
portion, the continuous ring or rope E of india-rubber may be compressed.
1 provide a sufficient number of screw bolts F, F, by means of which I effect
such compression of the india-rubber rope E between the moveable part B and
the fixed part B of the lid or cover, also between the said moveable part and
the upper edge of the soap pan as shall effect a joint sufficiently air-tight for
the purpose of my improvements.
This part of the arrangement is shewn on a larger scale in Fig. 3. G is a
pipe which passes through a stuffing-box II, attached to the fixed portion
B, of the lid or cover. This pipe also passes through a stuffing box J, which
is attached to a larger pipe K. The upper end of the pipe G is open, and
the lower end closed, but pierced with a number of holes to admit of the flow
of liquid materials through the same. A portion G, of this pipe has a male
screw formed on its outer surface.
I provide a bridge piece L (attached to
the fixed portion B of the lid,) which at L has a female screw encircling
the male screw G on the pipe G. By these means the pipe G inay be
raised or lowered in the soap pan A, by simply turning the pipe round to the
left or the right by means of the lever O, and thus the lower end may be
placed in a position to withdraw such portion of the contents of the soap pan,
as it may be desired to have taken out. The upper portion of the pipe K is
provided with a stop-cock, through which the materials elevated from the
soap pan may be conducted into spouts to be conveyed into soap frames or
otherwise disposed of. M is a pipe which is attached to the fixed portion B,
of the lid or cover, and extends nearly to the bottom of the soap pan. This
pipe is provided with a stop-cock M*, through which liquids or liquid materials
elevated from the soap pan may be conducted. This pipe is chiefly used for
the abstraction of alkaline or saline liquids from the soap pan; N is a pipe
attached to the soap pan A, through which bigh-pressure steam or compressed
air may be introduced into the upper portion of such pan. When I wish to
withdraw liquid materials from the soap pan A, by means of my Invention I
shut down the moveable portion B of the lid or cover, and thereby inclose the
ring or rope of india-rubber E, between the grooved portion of the lid, and the
upper part of the pan, also the fixed part of the lid, and by means of the

page_text: screw bolts F I give such compression of the india-rubber asy will effect
a sufficiently tight join; I then introduce high-pressure steam or compressed
air through the pipe. N, and if I wish to withdraw that portion of the contents
of the soap pan, which is at the lower part of the same, I open the stop-cock
of the pipe M when the pressure on the surface of the contents of the soap
pan will cause the lower portion of such contents to be elevated through the
pipe M, but if I wish to withdraw that portion of such contents as exist about
the middle of such pan, I open the stop-cock of the pipe G, (closing that of
the pipe M,) and those portions of the said contents, which surround the holes
in the pipe G, will be caused to flow through such pipe. The pipe G may
be lowered by means of its screw so as to withdraw such portions of the
contents of the soap pan as it may be found desirable to have withdrawn.
I have herein-before described such arrangement of apparatus as I consider
to be best adapted for effecting the objects of my Invention, but I do not confine
myself to such arrangement as this may be varied to some extent without
deviating from the nature of my Invention.
I claim as my Invention (secured to me by the hercin-before in part
recited Letters Patent,) the construction of apparatus to be used in the
manufacture of soap, which provides for withdrawing the contents of the pans
or vessels used in such manufacture by causing such pans to be closed with
lids or covers, and subjecting such contents to the pressure of steam or air
ou their surface, so as to cause the same to be elevated or driven through
a pipe or pipes communicating with the interior of such soap pan or vessel.
In witness whereof, I, the said William Gossage, have hereunto set my
hand and seal, this Third day of November, in the year of our
Lord One thousand eight hundred and sixty-two.
WILL".
(L.S.) GOSSAGE.
