IMPROVEMENTS IN SPIRIT MEASURING TAPS
Year: 1885

page_text: I, WILLIAM Ross of one hundred and ninety six Eglinton Street, Glasgow in the
County of Lanark, Brassfounder do hereby declare the nature of my invention for
"IMPROVEMENTS IN SPIRIT MEASURING TAPS" to be as follows:-
This invention relates to improved taps to be employed for discharging casks or
other vessels of their contents in certain uniform quantities or otherwise. The
main body of tap is a tube or cylinder with perforations or ports formed all round
the circumference a little from each end; a jacket is formed round the one end
ports with an out-let tube, the other end ports is inserted into a cask or other
vessel; a spindle is mounted with two disks (by preference of buff leather or cork)
fitting accurately into cylinder at equal distances with the ports, and fitted at out-let
end with knob or handle to draw out and in past the ports, so that one is sbut
when the other is open; the distance between the disks forming the contents of
the measure wanted; a small hole is put in top of jacket to admit air to allow the
contents between the disks to run out. The spindle can be made hollow and a
common tap put at out-let end instead of the knob or handle, to allow the contents
to be drawn in any quantity through the tap, without measuring the same.

page_text: I, WILLIAM Ross of 196 Eglinton Street Glasgow, in the County of Lanark
Brassfounder do hereby declare the nature of my invention for "IMPROVEMENTS IN
SPIRIT MEASURING TAPS" 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 Improvements in taps for measuring spirits or other
liquids, and is illustrated by the accompanying drawing which shows longitudinal
sections of two forms in which the tap may be made.
In Figure 1 the body of the tap is formed of a tube or cylinder A having inlet
and outlet ports at B and C respectively. Into the cylinder is fitted two discs or
pistons D. D. of cork, buff leather or other flexible material which are fitted or held
in position on a solid spindle E by two fixed metal washers F F. On the front end
of the spindle E is fitted a knob or handle G, the back end being provided with
two lock nuts H the outer of which is enlarged in diameter to form a stop against
the end of the cylinder A. The space between the metal washers F F forms the
measure or capacity of the tap; the ports B and C being placed at such a distance
apart that only one of them is open to the measuring space at the same time.
The tap is screwed or fitted into a cask or other Vessel, the inlet port C being inside.
When the knob or handle G is close to the body of the tap, the inlet port B is open,
and the outlet port C is shut, the measure being full. On the handle G being
pulled outward the inlet port B is closed and a little later the outlet port C is
opened, air being admitted through a small hole I to allow the contents of the
measure to discharge.
Figure 2 is similar to figure 1, with the following modifications:
1st Part of the body or cylinder A is surrounded by a jacket a.
2nd The ports B and C are formed of a number of holes round the circumference 2
of the cylinder A.
3rd The spindle E is formed of a tube communicating with a small tap which
takes the place of the handle G.
This arrangement allows of liquor being drawn, if desired, without measuring.
Having now particularly described and ascertained the nature of my said 3
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The arrangement or combination of parts forming the Improved Measuring
Tap herein described and illustrated in Figure 1.
2. The arrangement or combination of parts illustrated in Figure 2 so as to draw 3
any quantity (without measuring) through the small tap G substantially as herein
set forth.
