COMPLETE SPECIFICATION,
A New or Improved Device or Meter for Indicating the Quantity of
Liquid Passing Through a Tap, Pipe, or the like.
I, JOHN LANG of 4, Beak Street, Regent Street, London, 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:-
My invention relates to a new or improved device for indicating the quantity of
wine, spirits, beer, water or other liquid passing through a tap, pipe or the like, the
object of my invention being to provide a device of suitable construction which by
means of a suitable combination or train of wheels, together with a rotary fan or
bucket wheel, shall indicate approximately in half-pints, pints, quarts, gallons or
other convenient measure, the amount of beer, wine, spirit, water or other liquid
withdrawn or passed through the tap, pipe or the like.
In carrying my invention into practical effect I provide a rotary fan or bucket:
wheel of convenient form mounted upon a spindle and enclosed within an enlarged,
portion of the tap, so as to be rotated by the passage of the liquid. The spindle
passes through the sides of the tap and enters a case (of convenient shape and size
placed over the tap), where the ends of the spindle are provided with bevel wheels'
engaging with and actuating a suitable train or combination of other wheels, so as
to indicate upon a dial arranged on the top of the said case, the amount of liquid
withdrawn or passed through the tap, the aforesaid combination or train of wheels
being altered and varied according to the measure or quantities which are to be
indicated.
In order that my invention may be more fully understood, I will now proceed to
describe same with reference to the accompanying drawings in which
Fig. 1 is a front elevation of the indicating mechanism and bucket wheel, the
case and tap being in section.
Fig. 2 is a plan of the case showing indicating dials etc.
Fig. 3 is a side elevation of the tap and bucket wheel partly in section, the
position of the case containing the indicating mechanism being shown in dotted
lines.
Fig. is a front elevation of the tap, and the case containing the indicating
mechanism.
According to this invention a rotary fan or bucket wheel is provided, mounted
upon a spindles and contained within an enlarged portion p of the tap t so as to be
rotated by any liquid such as beer, wine, spirits, water or the like pussing through
the pipe pl and entering the enlarged portion p of the tap, at the top so as to fall
on the bucket wheel and rotate same, the motion being communicated to the train
of wheels contained within the case C by means of bevel wheels b, ', mounted
upon the ends of the spindles and meshing with other bevel wheels b', b, so as to
rotate the axes a, a', the axis a carrying toothed wheels t, c', which in their turn
actuate the toothed wheels w¹ and w³, while the axis a' carries the toothed wheel w
gearing with and actuating the toothed wheel w, the whole train or combination
of wheels being proportionately arranged so as to indicate upon the dial D the
amount of liquid, passed through or withdrawn from the tap, in any convenient
measure; for instance, where spirit is being withdrawn, the indicator i mounted
upon the axis a' may indicate quarterns, the motion being communicated to the
axis a through the wheels to, w, so that the indicator will indicate half-pints,

page_text: the indicator which receives its motion through the wheels w, w³, indicate pints,
the indicator mounted on the axis a showing quarts while the central hand or
indicator I actuated by the wheels w¹, w, represents the gallons of liquid withdrawn,
but the above arrangement or combination is only given by way of example, as the
aforesaid wheels may be increased or decreased in size and number and arranged
or combined in any suitable manner so as to indicate upon the dial the measure or
quantity of liquid according to requirements.
The end of the pipe p is furnished or fitted with a tap or cock c of any
convenient construction the stem of which is somewhat elongated for convenience
in turning and is supported by the cross piece c¹ secured in any convenient manner
to the case C.
It is obvious that this device may be made in various sizes to suit requirements,
and where the construction of the device will permit of it, some of the smaller
toothed wheels may be replaced by pinions while if necessary a ratchet and stop r
(Fig. 1) may be provided so as to prevent the hands or indicators from being
turned back for fraudulent purposes.
Although my improved device is more particularly described in connection with
a tap for the withdrawal of liquids, it is obvious that the said device may be used
in connection with a pipe or pipes at any intermediate point so as to indicate the
quantity of liquid passing through same.
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 :-
P
. I
1. The new or improved device or meter consisting essentially of the rotary fan
or bucket wheel mounted upon a spindle s and engaging with and actuating a
suitable train or combination of wheels so as to indicate the quantity of liquid
withdrawn, substantially as herein described and shown in the accompanying
drawings.
2. In a device such as above claimed the rotary fan or bucket wheel contained
within an enlarged portion p of the tap and actuated by the passage of the liquid,
substantially as herein described and shown and for the purposes specified.
3. The new or improved device or meter arranged, combined and operating
substantially as herein described and shown and for the purposes specified.
