Year: 1874

page_text: LETTERS PATENT to Rupert Goodall, of Armley, near Leeds, in the
County of York, Machinery Agent, for the Invention of "IMPROVE-
MENTS IN THE MEANS OR METHOD OF PURIFYING FOUL WATER OR SEWAGE,
MITRUMENTY
AND IN THE APPARATUS EMPLOYED IN CONNECTION
PROVISIONAL SPECIFICATION left by the said Rupert Goodall at the
Office of the Commissioners of Patents, with his Petition, on the
7th March 1874.
I, RUPERT GOODALL, of Armley, near Leeds, in the County of York,
5: Machinery Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MEANS OR METHOD OF PURIFYING FOUL WATER OR
SEWAGE, AND IN THE APPARATUS EMPLOYED IN CONNECTION THEREWITH," to be as
follows:-
This Invention has for its object the construction of apparatus to be
0 employed during the process of purification of foul water and sewage,
and in the combination of ingredients to be employed for purifying such
foul waters or sewage.

page_text: I employed a series of vessels within which the ingredients hereafter
described are received. Such vessels are provided each with a rotary central
shaft and mixing "dashers " or agitators, and a grate sieve or grates
herein-after referred to. Pipes branch from these vessels, conveying the
contents to a larger receiver, within which the foul water or sewage to
be treated is received. This general receiver also contains one or more
dashers perforated and revolving on hollow concentric shafts, so that the
contents of the vessels first referred to will on being supplied to the
hollow shafts be discharged through the perforations of the said dashers
ncar to the bottom of the journal, secures another dasher discharging its
contents near the surface of the water or at other point nearer or further
from the surface or bottom of the foul water, according to the length of
the respective hollow shafts on which the dashers are mounted, and such
dashers may have a rotation imparted through their shafts in opposite
directions.
The water flows from the general receiver through a fine grating,
following into a partitional end of a settling tank, from whence it flows
through another grating to the main tank or tanks.
Suppose I employ three of the vessels first referred to, No. 1 must
. contain a mortar or paste made of gas lime and animal carbon in about
equal proportions, previously ground together with water; No. 2 vessel
must contain a mortar or paste of slacked lime and animal carbon in
about said proportions, or slacked lime only; vessel No. 3 must contain
sesqui-persulphate of iron liquor. Water must be added to the mortar
or paste contained in the vessels No. 1 and 2 until made sufficiently
limpid to flow through the pipes connecting these vessels with the
general receiver. The contents of vessel No. 1 or of No. 2 will be
discharged through the perforated dasher at or near the bottom of the
general receiver, and the sesqui-persulphate of iron through the per-
foration of the upper dasher.
.
The grates in vessels No. 1 and 2 are for the purpose of securing a
subdivision of the mortar or parts, so as the more readily to mix with
the water added to render the same limpid. The foul water or sewage
to be so treated is admitted to the general receiver at a point about eight
'or ten inches from the bottom thereof, and such general receiver contains
'a quantity of fine ashes.
• The vessels No. 1 and 2 have an uniform supply of ingredients by
means of a self-acting and tilting measure.

page_text: About 25 lbs. of any of one of the three mortars or parts described is
sufficient for the treatment of 1,000 gallons of foul water or sewage, and
about one pint of the sesqui-persulphate of iron liquor will complete
the purifying of such quantity.
SPECIFICATION in pursuance of the conditions of the Letters Patent;
filed by the said Rupert Goodall in the Great Seal Patent Office on
the 7th September 1874.
TO ALL TO WHOM. THESE PRESENTS SHALL COME, I, RUPERT
GOODALL, of Armley, near Leeds, in the County of York, Machinery
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of March, in the year of
our Lord One thousand eight hundred and
,
in the
year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Rupert Goodall, Her special licence that
I, the said Rupert Goodall, my executors, administrators, and assigns,
or such others as I, the said Rupert Goodall, my executors, admini-
strators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter 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 "IMPROVEMENTS IN THE MEANS OR METHOD OF
PURIFYING FOUL WATER OR SEWAGE, AND IN THE APPARATUS EMPLOYED IN CON-
NECTION THEREWITH," upon the condition (amongst others) that I, the said
Rupert Goodall, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, 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..
NOW KNOW YE, that I, the said Rupert Goodall, do hereby declare
the nature of my said Invention, and in what, manner the same is to
be performed, to be particularly described and ascertained in and by

page_text: the following statement, and accompanying Sheet of Drawings, that is
to say: :-
This Invention has for its object the construction of apparatus to be
employed during the purification of foul water and sewage, and in the
combination of ingredients to be employed for purifying such foul waters
or sewage.
I employ a series of vessels A, within which the ingredients hereafter
described arc received. Such vessels are provided cach with a rotary
central shaft B and mixing "dashers" or agitators C, and a grate seive or
grates D, herein-after referred to. Pipes E branch from these vessels,
conveying the contents to a larger receiver F, within which the foul
water or sewage to be treated is received. This general receiver also
contains one or more dashers E' perforated and revolving on a hollow
concentric shafts E³, so that the contents of the vessel first referred to will
on being supplied to the hollow shafts be discharged through the per-
forations of the said dashers near to the bottom of the general receiver,
another dasher G discharging its contents near the surface of the water,
or at the other point nearer or further from the surface or bottom of the
foul water, according to the length of the respective hollow shafts on
which the dashers are mounted, and such dashers may have rotation
imparted to their shafts in opposite directions by bevil gearing.
The water flows from the general receiver F through fine gratings J,
flowing into a partitioned end of a settling tank K, from whence it flows
through. another grating L to the main tank or tanks M.
Suppose I employ three of the vessels first referred to, No. 1 must
contain a mortar or paste made of gas lime and animal carbon in about
equal proportions, previously ground together with water; No. 2 vessel
must contain a mortar or paste of slaked lime and animal carbon in
about equal proportions or slaked lime only; vessel No. 3 must contain
sesqui-persulphate of iron liquor. Water must be added to the mortar
or paste contained in the vessels No. 1 and 2 until made sufficiently
limpid to flow through the pipes connecting these vessels with the
general receiver. The contents of the vessel No. 1 or of No. 2, or both,
will be discharged through the perforated dasher E' at or near the bottom
of the general receiver F, and the sesqui-persulphate of iron in vessel
No. 3 through the perforation of the upper dasher G.
The grates D in vessels No. 1 and 2 are for the purpose of securing a
subdivision of the mortar or paste, so as the more readily to mix withi

page_text: the water added to render the same limpid. The foul water or sewage
to be so treated is admitted to the general receiver at a point P, about
eight or ten inches from the bottom thereof, and such general receiver
contains a quantity of fine ashes.
The vessels No. 1 and 2 have an uniform supply of ingredients by
means of a self-acting and tilting measure R.
About 25 pounds of any of one of the three mortars or pastes described
is sufficient for the treatment of 1,000 gallons of foul water or sewage,
and about one pint of the sesqui-persulphate of iron liquor will complete
the purifying of such quantity.
Having thus described the nature of this my said Invention, and
shewn by Drawings how the same is to be performed or carried into
practical operation, I would have it understood that I do not confine
myself to the precise details herein given, as the same may be varied
without departing from the main features thereof; but what I claim as
my Invention, and what I believe to be new is, the general combination
of the materials as above described, and the construction and arrangement
of apparatus whereby the ingredients compounded as described are
introduced into the general receiver at regular intervals and in regular
quantities, substantially as shewn and described.
In witness whereof, I, the said Rupert Goodall, have hereunto set
my hand and scal, this Fourth day of September, One thousand
eight hundred and seventy-four.
RUPERT GOODALL. (L.S.)
