IMPROVEMENTS IN APPARATUS FOR MAKING ARTIFICIAL, MINERAL, AND AERATED BEVERAGES, WHICH ARE ALSO APPLICABLE FOR other PURPOSES
Year: 1884

page_text: I JAMES MCEWEN of the Blake Street Brass Works, Stretford Road, Manchester,
in the County of Lancaster, Aerated Water Engineer, do hereby declare the nature
of my Invention for "IMPROVEMENTS IN APPARATUS FOR MAKING ARTIFICIAL,
MINERAL, AND AERATED BEVERAGES, WHICH ARE ALSO APPLICABLE FOR other
PURPOSES," 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 that part of the machine used for pumping gas and
water for making aërated beverages, such as, soda-water, lemonade, gingerbeer,
and so forth, and consists principally in the construction of the seatings for the
suction and delivery valves, so arranged that they can be renewed or replaced
without disturbing the pump; also in an improved arrangement of a single valve
or tap for admitting gas and water in equal, or unequal quantities, or separately as
desired; thereby increasing the effective power of the pump, as well as reducing
the cost from repairs to a minimum. The valve seats are also applicable to other
pumps, for pumping water or other liquids, wherein the temperature of the same
dues not exceed 150 degrees Fahrenheit.
This Invention is designed to overcome a want long felt by the trade, for in all
such pumps made hitherto the valve seatings are secured by convenient means to
the underside of the valves; rising and falling with them, with the result of their
early destruction, which is a source of continual repairs and expense. In machines
at present in use a separate tap or valve is used for both gas and water, wherein
by ny improvements a single valve is produced to effect the double purpose in an
economical and novel way.
These improvements are accomplished by providing the suction and delivery
valve boxes with flat surfaces on which is placed suitable stationary seats composed
of leather, india-rubber, or other analogous substances; being held in position by
suitable nuts or other equivalents. The seats are provided in the centre or otherwise
with openings over which the valves sit; the latter being encased in suitable
chambers to maintain their true position and ensure their rising and falling with
the pumps action.
In order that my Invention may be fully understood and readily carried into
operation, I will proceed to describe the annexed Sheet of Drawings, reference
being made to the figures and letters marked thereon.
Fig. 1 is a sectional elevation of a valve box containing the suction and delivery
valves of an aërated water pump with my improvements applied. A is the valve
box; B the thoroughfare connecting it to the force pump; C is the suction valve;:

page_text: The advantages of the valve seatings F, F, are, that they are more durable and
less liable to fracture than those moving with the valves, thereby ensuring a more
regular action of the pump; at the same time being easy of renewal, and less
costly.

The three-way tap or valve I for supplying water and gas to the pump is
constructed with the openings 0, 0, so that both can be admitted at once, as shewn
in the Drawings in Fig. 1, through the pipes K, and passed or drawn by the pump
through the conical opening P to the suction valve C. The conical opening P is
so constructed that when either of the openings O are full open to the inlet pipes K,
the side of the conical opening next to the open passage is flush with the
opening H in the pipe leading from the tap to the valve C, as shewn in Fig. 4.
By swivelling the tap as in Fig. 4, one opening is closed, when gas or water are
admitted separately as the case may be according to what is conveyed by the open
pipe to the tap.
The opening of one passage can be reduced, and the opposite one increased,
according to the amount of gas and water required, as in Fig. 5. Fig. 6 is an
outside view of the stopper I and handle R with the index plate S, shewing the
position of the openings in the valve, with the amount of opening given to each
thoroughfare, or, when shut to both, which is effected by swivelling the finger to
the mark against which the word "Shut" is placed.
When the handle is in the
position shewn in Fig. 6, the valve or tap I is full open as in Fig. 1 to admit both
gas and water in equal quantities. The stop Y on the index plate S is provided
for the purpose of preventing the valve or tap I being swivelled beyond full open
when admitting water only, as in Fig. 4; the stop W is to ensure its being stopped
at the correct point when shut to both gas and water. The divisions on the index
plate S are provided to enable unequal quantities of either gas or water to be
admitted, by increasing or decreasing the inlets as shewn in Fig. 5.
The advantage of this three-way tap or valve is, that it dispenses with one of
the taps at present in use, thereby reducing the cost, as well as being easy of
manipulation. Another is, that by its use it is impossible to bump or chock the
pumps.

page_text: 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. The use and construction of the stationary valve seatings F, composed of
leather, india-rubber, or other analogous substances when applied to valves used in
connection with aërated water pumps, or in other pumps wherein the temperature
of the water or other liquid being pumped does not exceed 150 degrees Fahrenheit,
for the purposes described, and as shown on the Drawings.
2. The use and construction of the three-way valve or tap I, with the conical
opening P, and the angular openings O, for the purpose described, and as shewn
on the Drawings.
