I DAVID ALFRED AIRD of Helmet Court, Strand, Middlesex, Gentleman, do
hereby declare the nature of my said invention to be as follows:-
This invention relates to novel arrangements or constructions in or by which fixed
quantities of liquid can be drawn and an indication electrically be recorded of each
movement of the levers or handles by which the taps are operated.
According to one arrangement I arrange four taps on a branch pipe between the
liquid container and the nozzle, the plugs of which taps are connected in a suitable
manner by levers that the movement of the main lever or handle for opening one
plng closes one or more of the others. One of said taps is connected to the spigot
end of the branch, another to the vent, the third to the liquid container at a higher
level than the spigot end and the fourth tap is connected with the nozzle.
The shoulder of one of the plugs carries a contact piece which when the apparatus
is used records electrically on a counting or numbering machine each successive action
or draw off of liquid.
Instead of four taps being arranged on a branch as above described there may be
only two in which case I use one as a plunger so that when the plug is turned in
line for being charged from the liquid container the plunger or diaphragm is operated
and the branch becomes charged. The turning of the tap in some cases with the
plunger and its branch shnts off the inlet and opens the outlet for the quantity con-
tained in the branch to flow out through the nozzle or be pushed through by the
plunger.
This tap is also connected with electrical appliances for recording the movements
of the tap which in turn would register the withdrawals of the liquid.

page_text: I, DAVID ALFRED AIRD, of Helmet Court; Strand, Middlesex, Gentleman, do
hereby declare the nature of this 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 novel arrangements or constructions, in or by which,
fixed quantities of liquids can be drawn and an indication electrically be recorded
of each movement of the levers or handles, by which the taps are operated.
According to one arrangement, such as I show at Figure 1 of the annexed drawings,
I arrange four taps A, B, C, D, on a branch pipe E between the liquid container F
and the nozzle G, the plugs of these taps A, B, C, D, are connected by levers H, I, J,
so that the movement of the main lever or handle K for opening one plug, also
opens another plug and closes two of the others. One of said taps A is connected
to the spigot end of the branch E, another B to a vent pipe L, the third C to the
second vent M and the fourth tap D is connected with the nozzle G.
The shoulder of one of the plugs, or its arm N carries a contact piece P, which
when the apparatus is used, records electrically through the other contact piece Q on
a counting or numbering machine, each successive action or draw off of liquid.
Instead of four taps being arranged on a branch as above described, there may be
only one, in which case I use a plunger R, as at Figure 2, so that when the plug is
turned in line for being charged from the liquid container the plunger or diaphragm R
is lifted and the branch E becomes charged. The turning of the branch E and tap
shuts off the inlet and opens the outlet for the quantity contained in the branch E to
flow out through the nozzle G or be pushed through by the plunger R.
This tap has contact pieces also connected with electrical appliances for recording
the movements of the tap which in turn would register the withdrawals of the
liquid.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The apparatus shown at Figure 1 of the annexed drawings and the arrangement
of the levers for the purposes described when such apparatus has electrical contacts
as part of same for indicating the movement of the taps as set forth.
2. The combined branch and measured liquid container operated as described when
in connection with electrical recording appliances as set forth and substantially as
shown at Figure 2 of the annexed drawings.
