Improvements in Drawing
Year: 1899

page_text: I, LOUIS BERNILARD BARON, of 4 to 6, Saint James' Place, Allgate, in the City
of London, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
-
My invention relates to improvements in drawing taps for aerated waters and
the like.
For drawing off aerated waters particularly where such are made on a large
scale as by machines which aerate or carbonate water drawn directly from the
main by bringing it into contact with the gas, so that it may be taken off at once
for consumption it is desirable to use a drawing tap in which the liquid is
allowed to first enter a chamber after which a snifting valve is opened to let off
the gas from the top of such water and finally an outlet tap is opened to allow
the water to flow out into the glass or receptacle which it does quickly and
without having its contained gas knocked out of it by its rapid rush into the
receptacle.
My invention relates to this class of drawing tap and according to same I
form the inlet valve in such a manner that the liquid' passes through a passage
in the moveable part of the valve and back into the body of the valve before
going to the chamber such moveable part being adapted to be turned so as to
put the passage to the chamber in connection with an outlet passage. The move-
able part of the valve is connected by a link or lever with the outlet valve and one
or other of these valves is provided with a handle for operating it such handle
according to my arrangement as above described effecting the whole of the
movement required for operating the tap.
To draw off the liquid the handle is moved with the effect of opening the
inlet and closing the outlet valves and causing the chamber to be filled, a
further movement of the handle places the upper part of the liquid in the
chamber in communication only with the outlet so that the snifting of the gas
takes place and the same movement or a continuation of it after the gas is let
off opens the outlet valve and' allows the water to flow away."

ODKALNICATION
Improvements in Drawing Taps for Aerated Waters and the like.
I, LOUIS BERNHARD BARON, of 4 to 6, Saint James' Place, Aldgate, in the City
of London, Manufacturer, do hereby declare the nature of this invention and in
Price 8d.1

page_text: what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to improvements in drawing taps for aerated waters and
the like.
For drawing off aerated waters particularly where such are made on a large
scale, as by machines which aerate or carbonate water drawn directly from the
main, by bringing it into contact with the gas, so that it may be taken off at once
for consumption; it is desirable to use a drawing tap in which the liquid is
allowed to first enter a chamber after which a snifting valve is opened to let off
the gas from the top of such water and finally an outlet tap is opened to allow
the water to flow out into the glass or receptacle which it does quietly and
without having its contained gas knocked out of it by its rapid rush into the
receptacle.
My invention relates to this class of drawing tap and according to same I
form the inlet valve in such a manner that the liquid passes through a passage
in the moveable part of the valve and back into the body of the valve before
going to the chamber such moveable part being adapted to be turned so as to
put the passage to the chamber in connection with an outlet passage. The move-
able part of the valve is connected by a link or lever with the outlet valve and one
or other of these valves is provided with a handle for operating it such handle
according to my arrangement as above described effecting the whole of the
movement required for operating the tap.
In the accompanying drawing.
Fig. 1 is a sectional elevation of the drawing off tap on line of Fig. 3.
Fig. 2 is a plan of Fig. 1 partly in section on line y-y.
Fig. 3 is an elevation taken at right angles to Fig. I and partly in section on
line of Fig. 2.
Figs. 4, 5, and 6 are diagrams shewing different positions of the upper valve.
The apparatus shewn consists of a cylinder 50 preferably of glass held in
upper and lower metal caps 51, 51 by means of screwed rods 52 which are
provided with nuts by which the upper cap may be removed. To the lower
cap is attached an outlet valve of some suitable form. As shewn it consists of a
disc 53 carried by a spindle 54 said disc seating by its washer 53 on a seat on
the valve casing 55 and being held there by a spring 56 bearing against an open
armed or star piece 57 which also supports the spindle 54. Or in place of this
the valve 53, 53" may be on a line level with the bottom of the chamber the
spindle 54 being supported by a bridge piece above same which performs the
same function as the piece 57.
The lower end of the spindle is adapted to be raised by a lever 58 which hooks
on a pin 59 in the valve casing or is pivoted therein. The other end of this lever
passes through a slot in a connecting link 60 pivoted to one arm of a lever 61
the other end of which has a handle 62. This lever is attached to a valve
stem 63 held in a glaud 64 screwed into a valve casing 65.
The valve casing is provided with a washer 66 of some suitable material'
against which the valve head 67 abuts and such head has a passage 68 therein
provided with two ports or openings as shewn in Fig. 2.
The valve casing has a passage 69 communicating with a passage 70 into the
cylinder 50 and also a passage 71 communicating with a pipe 72 which has an
open end and forms an escape pipe for the gas. Both these passages 69 and 71
pass through the washer 66 and terminate as ports or openings on the face of
Name. The valve casing has also a further passage 73 communicating with a
passage 73 in a neck 74 which is adapted if desired to be screwed or affixed to
the casing 43 of the carbonating apparatus and is in connection with the pipe
of same carrying the carbonated water.
The operation of the apparatus is as follows:-
The handle. 62 may be norinally kept in the position indicated by line A
Figs. 1 and 6'the supply of carbonated water being cut off and the outlet valve

page_text: open for draining purposes. To fill the cylinder 50 the handle 62 is now pushed
back into the position B shewn in Figs. 1, 2, 3 and 4 to bring the passage 68
into the position shewn where it will be seen that it connects passages 69 and 73
so that the carbonated water can pass from the latter into the former down
passage 70 into cylinder 50 which is thus filled.
The handle is now drawn forward again into position C Figs. 1 and 5 so that
the passage 68 is put in the position shewn where it connects passages 69 and 71
with the result that the gas on the upper surface of the water in cylinder 50
and which has forced the water into same is allowed to escape off from such
upper surface into the open air; a continued movement of the handle in the
downward direction back into the position A shewn in Figs. 1 and 6 raising
the link 60 and thereby lifting lever 58 and opening the outlet valve 53 where-
upon the water in cylinder 50 is allowed to flow quietly out into the glass or
receptacle. The opening of passage 71 in the washer G6 is preferably made
elongated as shewn in the diagrams Figs. 4 to 6 so that the snifting of the gas.
may be effectual and so that when the valve is in the position last described the
passage 68 remains in connection with passage 71 and allows air to enter the
chamber.
It will be seen by this arrangement only two movements of a single handle
are required first a slight backward movement to fill the cylinder with the
carbonated water and then a forward movement which first puts the upper part of
the cylinder in communication with an escape pipe to relieve the gas pressure
and then opens the outlet valve to allow the water to flow away.
It will be understood that other arrangements of valves may be employed for
this purpose so long as they are capable of being worked by a single handle.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In a drawing off tap a chamber provided with an inlet passage for the
carbonated liquid a snifting passage for the gas and an outlet passage for the.
liquid all controlled by a single handle substantially as described.
2. A drawing off tap having an inlet valve having a passage in same adapted
to put the carbonated water inlet in communication with the chamber of same
and the chamber in connection with a snifting passage, after the inlet is closed
and an outlet valve connected to the inlet valve by a link or lever and a single
handle for moving both, valves substantially as described.
3. A drawing off tap for carbonated liquids consisting of the chamber 50, an
outlet valve 53, an inlet valve having a head 67, a passage 68 in same, a valve
casing 65 having passages 69, 70, 71, 73 therein, three of such passages com-
municating through the valve with the reservoir of carbonated liquid and with.
the chamber 50 and one with an escape pipe and the chamber 50 through the
valve; and means connecting the inlet and outlet valves so that the chamber may
be first filled then relieved of gas from the top of the liquid in same and the
outlet subsequently opened all the movements being effected by a single handle
substantially as described.
Dated this 22nd day of March 1900.
