PROVISIONAL SPECIFICATION.
Improvements in the Cylinders or Saturators of Soda Water
Machines, the said Improvements being also applicable to other
Gas Saturating Machines.
I, ALEXANDER MACDOUGALL, Lissa Cottage, Bonhill, Alexandria, N.B., Aerated
Water Manufacturer, do hereby declare the nature of this invention to be as
follows:
This invention relates to improvements in the cylinders or saturators of soda
water machines, the said improvements being also applicable to other gas saturating
machines, and consists in dividing the agitator in the cylinder into two parts,
the two parts being caused to revolve in opposite directions so as to impart greater
commotion to the water in the cylinder whereby a greater volume of gas is taken
up by the water. This reverse action may be effected by mounting the two parts
of the agitator upon a shaft which passes through the water containing cylinder
which is usually a horizontal cylinder. The agitators may consist of a frame or
frames having zig-zag or other shaped arms or agitators which are fixed upon the
shaft. Each shaft portion of the agitator may be mounted upon its own shaft,
the two shafts running in line and their ends being brought into proximity with
each other at the centre of the length of the cylinder; each shaft extending out
from the end of the cylinder and having on it a driving pulley. The shaft passing.
through a stuffing box in the end of the cylinder. The two shafts would be driven
simultaneously, the one pulley being driven in the reverse direction by a crossed
belt. The outer ends of the shaft may be supported within fixed journals at the
two ends of the apparatus and the ends of the shafts which are at the central part
of the cylinder are supported by means of a central brush or bearing within the
cylinder.
The cylinder is preferably divided into two parts at the centre of its length, the
two parts being bolted together.

Machines, the said Improvements being also applicable to other
Gas Saturating Machines.
I, ALEXANDER MACDOUGALL, Lissa Cottage, Bonhill, Alexandria, N.B., Aerated
Water Manufacturer, do hereby declare the nature of this invention, and in what

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to improvements in the cylinders or saturators of soda
water machines, the said improvements being also applicable to other gas saturating
machines, and consists in dividing the agitator in the cylinder into two parts,
the two parts being caused to revolve in opposite directions so as to impart greater
commotion to the water in the cylinder whereby a greater volume of gas is taken
up by the water. But in order that my said invention may be more readily under-
stood and easily carried into effect I will proceed to describe the same with reference
to the accompanying drawings in which Fig. 1 is an elevation partly in section
and Fig. 2 a cross section of a cylinder or saturator of a soda water machine shew-
ing my improvements applied thereto.
Referring to the said drawings I employ an agitator formed in two parts A so
arranged within the cylinder B that they can revolve in opposite directions. This
reverse motion may be effected by mounting the two parts A of the agitator upon
shafts C running in line and having their ends, which are in proximity with each
other, supported at the centre of the length of the cylinder by a bush or bearing D.
This bearing may be connected by arms to a ring & interposed between the flanges
of the two sections of the cylinder and bolted together.
The agitators may consist of a frame or frames E having zigzag or other shaped
arms e as shewn.
The shafts C extend out from and pass through stuffing boxes F at the ends
of the cylinder and are provided with pulleys G driven simultaneously, the one
pulley being driven in the reverse direction by a cross belt.
The outer ends c of the shafts may be supported within fixed journals H situated
at both ends of the apparatus.
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:
1. In the cylinders or saturators of soda water and other gas saturating machines,
forming the agitator in two parts each revolved in opposite directions so as to im-
part greater commotion to the water in the cylinder, substantially as and for the
purpose hereinbefore described and shewn in the accompanying drawings.
2. The arrangement, construction and mode of operating the agitator in the
cylinders or saturators of soda water and other gas saturating machines, substan-
tially as herein before described and shewn in the accompanying drawings.
Dated this 9th day of March 1898.
