Year: 1865

page_text: LETTERS PATENT to William Saunders Parfitt, of Devizes, in the
County of Wilts, Engineer and Millwright, for the Invention of "An
IMPROVED MACHINE FOR THE MANUFACTURE OF AËRATED WATERS."
Sealed the 28th December 1865, and dated the 5th July 1865.
PROVISIONAL SPECIFICATION left by the said William Saunders Parfitt
at the Office of the Commissioners of Patents, with his Petition, on the
5th July 1865.
I, WILLIAM SAUNDERS PARFITT, of Devizes, in the County of Wilts,
Engineer and Millwright, do hereby declare the nature of the said Invention
for "AN. IMPROVED MACHINE FOR THE MANUFACTURE OF AËRATED WATERS," to
be as follows:-
The object of this Invention is an improved machine for the manufacture
of aërated waters, which machine shall combine in a convenient and portable
form the several parts known (with reference to machinery employed in the
manufacture of aërated waters) as the gasometer tank and gasometer, a retort
or retorts for supplying the necessary gas or gases, the pump with water
cistern or cisterns for supplying the same, the condenser and agitator, as also
bottling apparatus and tying-down press.
The accompanying Sheets of Drawings represent three different views of a
machine constructed according to my Invention. For the purposes described
I form or fix the gasometer tank a (containing the gasholder a¹) upon a

page_text: suitable sole plate 6, and attach thereto the pump c and condenser & situated
with their axes in the same line with each other, and I prolong the piston
rode of the pump and pass it into the condenser d for the purpose of giving
motion to an agitator therein. An alternate motion is imparted to the pump
piston rod by means of a revolving crank f, the 'pin of which takes into a
suitable slot e¹ formed in or attached to the piston rod é at right angles to its
length. The retort or generator g for producing the required gas, the water
cistern (or cisterns) for supplying the pump, the bottling apparatus i, and
tying-down press j, instead of being separate as usual are also attached to
and form part of the machine, thus greatly increasing the compactness and
portability of the whole.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Saunders Parfitt in the Great Seal Patent Office on
..the 4th January 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
SAUNDERS PARFITT, of Devizes, in the County of Wilts, Engineer and Mill-
wright, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of July, in the year of our Lord One thousand
eight hundred and sixty-five, in the twenty-ninth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
William Saunders Parfitt, Her special licence that I, the said William Saunders
Parfitt, my executors, administrators, and assigns, or such others as I, the said
William Saunders. Parfitt, my executors, administrators, 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
Treland, the Channel Islands, and Isle of Man, an Invention" for." An
IMPROVED MACHINE FOR THE MANUFACTURE OF AERATED WATERS," upon the
condition (amongst others) that I, the said William Saunders Parfitt, 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.

page_text: . NOW KNOW YE, that I, the said William Saunders Parfitt, 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 the
following statement (that is to say):-
The object of this Invention is an improved machine for the manufacture
of aërated waters, which machine shall combine in a convenient and portable
form the several parts known (with reference to machinery employed in the
manufacture of aërated waters) as the gasometer tank and gasometer, a
retort or retorts for supplying the necessary gas or gases, the pump with
water cistern or cisterns for supplying the same, the condenser and agitator,
as also a bottling apparatus and tying-down press.
The accompanying Sheet of Drawings represents three, different views of a
machine constructed according to my said Invention (Fig. 1 being a front
elevation, Fig. 2 a side elevation, and Fig. 3 a back elevation of the same),
for the purposes of which I form or fix the gasometer tank a (containing the
gasholder a¹) upon a suitable sole plate 6, and attach thereto the pump c and
condenser d situated with their axes in the same line with each other, and I
prolong the piston rode of the pump, and pass it into the condenser d for the
purpose of giving motion to an. agitator therein. An alternate motion is
imparted to the pump piston rod by means of a revolving crank.f, the pin of
which takes into a suitable slot e¹ formed in or attached to the piston rod e at
right angles to its length. The retort or generator 9 for producing the
required gas, the water cistern (or cisterns) h for supplying the pump, the
bottling apparatus i and tying-down press j, instead of being separate as usual,
are also attached to and form part of the machine, thus greatly increasing
the compactness and portability of the whole.
The pump c communicates by means of a pipe h¹ with the water cistern h,
and in like manner by means of a pipe g¹ with the retort, generator, or
vessel 9, wherein the required gas or gases is or are generated; thus by its
action drawing a supply composed partly of water (drawn through the pipe h¹
from the cistern h) and partly of gas or gases (drawn through the pipe g¹
from the retort, generator, or vessel 9), and forcing it through the pipe-k
(Fig. 2) into the condenser d, in which a considerable pressure is maintained,
and wherein they (the gas or gases and water) are intimately mixed by means
of the perforated agitator attached to and moving with the piston rod
e, thus
dispensing with the gearing usually employed, as will be clearly understood
by reference to Fig. 4, which is a vertical section through the pump c and
condenser d. The condenser d is provided with a safety valve and lever d¹
for the purpose of allowing the escape of any excess of pressure, and commu-

page_text: nicates by means of a pipe m with the bottling apparatus i, whereby the
combined water and gas or gases are bottled in the ordinary manner, the
corks being subsequently secured as usual by means of the tying-down press j,
which also, according to my Invention, is permanently attached to and forms
à part of the combined apparatus. The balancing of the gasholder and other
details not herein specially described may be carried out in the usual or any
other convenient manner, as will be well understood by makers of machinery
for the manufacture of aërated waters.
Fig. 5 represents a vertical section of a modified arrangement of the
pump c, in which a solid plunger n working upwards from beneath is
employed, and which is connected with the slotted piston rode by means of
the frame o, as shewn, suitable openings and valves p being provided at the
upper end of the pump barrel for the inlet and exit of the water and gas or
gases to and from the barrel.
Having now fully described and ascertained the nature of my said
Invention, and the manner in which the same may be performed, I would
have it understood that I do not confine myself to the precise details described,
as the same are capable of being variously modified without departing from its
distinguishing features; but that I claim,-
Firstly, the combination of the several parts necessary for manufacturing
aërated waters in one machine carried upon a foundation plate or frame,
substantially as described.
Secondly, the method of working the agitator employed for mixing the gas
or gases and water by attaching it to a prolongation of the piston rod of the
pump, either directly or otherwise, without the intervention of gearing,
substantially as described.
Thirdly, the general arrangement and combination of parts constituting a
machine or apparatus for the manufacture of aërated waters, substantially as
described.
In witness whereof, I, the said William Saunders Parfitt, have hereunto
set my hand and seal, this Twenty-ninth day of December, in the
year of our Lord One thousand eight hundred and sixty-five.
WILLIAM SAUNDERS PARFITT. (L.S.)
