COMPLETE SPECIFICATION.
An Improved Gas Washer for Use in the Manufacture of Aerated
Liquids.
I, JAMES MOEWEN of 11 Rushton Street, Hulme, Manchester in the County of
Lancaster, Aerated Water Engineer, 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:-
This invention relates to an improved double purifier or gas washer for machinery
employed in the manufacture of aerated and mineral waters and has for its object
that of more thoroughly purifying gas employed in the manufacture of the aforesaid
waters by first drawing the gas through the lower purifying vessel and then through
the upper purifying vessel, also to allow of the same being filled and cleansed without
admitting atmospheric air and taking the chambers to pieces.
Fig. 1 is a sectional elevation of my improved double purifier-Fig. 2 is an outside
view of same, and Fig. 3 is a sectional plan through line A. B in Fig. 1.
C is the bottom purifier made of copper or other analogous materials, and is provided
with the top and bottom covers D and E respectively. The purifier C is fitted with
the perforated discs F and F¹, between which is placed broken lime stone, broken
marble, or other analogous substance to diffuse the gas and neutralise any acid that
may pass with the gas. To the cover D is attached the nozzle G to the underside of
which is screwed the tube H, the bottom end screwing into the perforated disc F¹.
The bottom end of the tube H is solid and is chased to receive the nut H¹ to, secure
the casing C between the covers D and E. In the nozzle G is screwed the connecting.
piece I, on which is mounted the top purifier K provided with the covers J and L°;
the cylinder being of glass to enable the operation of the same to be easily ascertained.
The cover L is fitted with the projection M in which is screwed the tube N. The
projection or upper nozzle M is secured in position by the nut O, the latter being
screwed at its upper end to receive the nut P provided with the union Q to attach the
pipe R communicating with the gas pipe of the pump. The double purifier is attached
to the framework of the agitator or other suitable place by the arm or support S on
the connecting piece I ; the latter being also provided with the gas inlet 1 from the
gas-holder.

page_text: When it is desired or requisite to charge the purifiers C and K with water it is
effected by removing the screwed plug from the inlet of the syphon pipe p, when
water can be supplied until it rises sufficiently high in the purifier K to flow down
the internal pipe d in the purifier C. When cleaning or washing out of the purifiers
is requisite the screw Z is removed from the outlet pipe Y on the bottom purifier, and
enough water is poured in at the pipe and run out at the screw Z to thoroughly
cleanse the purifiers, which is ascertained by running water in until it comes out clear;
the syphon pipe p preventing the admission of air during such operation. The small
hole is provided in the pipe N to prevent the water syphoning out of top purifier
during the process of cleansing.
This apparatus operates as follows:-Gas is admitted from the gas-holder by the
pipe T, from whence it passes down the internal tube U and through the holes a in
the bottom end of the tube H into the cavity or chamber V beneath the perforated
disc F', the gas then passes through the perforations and the broken lime stone,
broken marble, or other analogous substance and water and the perforated disc F into
the space above the latter, from whence it passes through the openings c, up the internal
pipe d, down the pipe N, and out by the holes g into the purifier K, passing through
the water in the latter and up through the holes to the outlet pipe R which conveys
the purified gas to the valve for mixing gas and water prior to being pumped to the
condenser or otherwise.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
For purifing gas employed in the manufacture of aerated and mineral waters the use
and employment of a double purifier, constructed and arranged so that the gas passes
first through the bottom purifier and then through the top purifier, with the means for
filling and cleaning the double purifier without admitting atmospheric air, applied and
operating substantially as described and as shown on the drawings.
