I GEORGE HENRY SMITH, of No 207, Victoria Park Road, in the county of
Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
My improvements consist in so constructing measuring taps that the minimum
risk of derangement and non-liability to leak is obtained.
In order to carry out my invention I provide a cylinder made of any suitable
material such as brass, pottery or glass, the capacity of such cylinder being
equivalent (minus a slight portion consisting of other necessary parts) to the
maximum quantity the tap is to measure.
The bottom of the cylinder I construct of a suitable shape to form what may be
termed the cylinder cover and also to contain a two way cone cock whose axis.
runs in a vertical line with the cylinder.
This cone at the bottom part is hollow and extends outwards below the casing
thus forming the spout for the liquid drawn off.
Outside this spout I place a casting of a suitable shape which serves the double
purpose of a washer and handle to turn the tap by. This bottom part also forms
one of the connections to the barrel or vessel containing the liquid to be measured.
Extending up from the cylinder cover and connected by suitable ports to the
casing of the two way cone cock I attach pipes extending to any desired height
into the cylinder. In the plug of this cone cock passages are set apart the same
distance as the ports referred to in the casing.
The plug or cone cock extends upwards to the top of the cylinder but the size
of the plug may here be reduced. This extension of the plug engages into a one.
way cone cock in the top of the top cylinder cover. Extending from the casing of
the top cone cock, is a pipe forming the other connection of the barrel referred to.
Holes are made in the cone casing at similar distances apart to which the ports
are in the lower casing. The plug of the top cone extends upwards and can be
adapted to actuate an indicator or counter which can be of any suitable construction.
The operation is as follows:
The tap in its normal condition is closed, in which position the lower two way
cone cock is in direct communication with the lower connection to the supply and

page_text: the chamber is filling. The top cone is now in communication with the upper
connection of the barrel and the air is being forced up this pipe. On the cylinder
being filled the liquid is in equilibrium owing to the double connection with the
barrel.
In turning the handle the action is as follows:
1st. Both connections from the barrel are simultaneously cut off.
2nd. The outlet passage in the lower cone cock which is connected to the
hollow spout is brought in communication with the first port in the casing; this
port is connected to the longest pipe in the cylinder, at the same time the passage
in the top cone cock is brought in communication with the first opening in the
casing. The liquid now being in connection with the lower plug and in connection
with the air through the top one the cylinder empties itself until the liquid
comes to the level of the first pipe; on further rotation of the cone cocks commu-
nication is made with the next pipes and the same result occurs. It will thus be
obvious that according to the size of the cylinder the number of pipes and the
various lengths of same, any varying quantities may be drawn from one measure..
It will be obvious that the said pipes can be made telescopic so as to allow of
their being adjusted according to the quantity of liquid to be drawn off.
Dated the 8th day of December 1885.

I GEORGE HENRY SMITH, of No 207, Victoria Park Road, in the county of
Middlesex, Engineer 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 improvements consist in so constructing measuring taps that the minimum
risk of derangement and non-liability to leak is obtained.
In order to carry out my invention I provide a cylinder made of any suitable
material such as brass, pottery or glass, the capacity of such cylinder being
equivalent (minus a slight portion consisting of other necessary parts) to the
maximum quantity the tap is to measure.
The bottom of the cylinder I construct of a suitable shape to form what may be
terined the cylinder base cap and also to contain a two-way cone cock whose axis
runs in a vertical line with the cylinder.
This cone at the bottom part is hollow and extends outwards below the casing
thus forming the spout for the liquid drawn off.
Outside this spout I place a casting of a suitable shape which serves the double
purpose of a washer and handle to turn the tap by-The bottom part or cover of
the cylinder is formed with one of the connections to the barrel or vessel containing
the liquid to be measured.
Extending up from the cylinder base cap and connected to suitable ports in the
casing of the two-way cone cock I attach pipes extending to any desired height
into the cylinder. In the plug of this cone-cock, passages are set apart the same
distance as the ports referred to in the casing.
The plug or cone cock extends upwards to the top of the cylinder but the size
of the plug may here be reduced. This extension of the plug engages into a one-
way cone-cock in the top of the top cylinder cover. Extending from the casing of
the top cone-cock, is a pipe forming the other connection of the barrel referred to.
Air-holes are made in the cone-cock casing at similar distances apart to which the
ports are in the lower casing. The plug of the top cone extends upwards and
can be adapted to actuate an indicator or counter which can be of any suitable
construction.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawings in which figure 1 represents
a front elevation and figures 2 and 3 are vertical transverse sections of a tap for
measuring and registering the quantity of liquid passed therethrough constructed
according to my invention; figure 4 is a plan of the same with the top cylinder
cover removed; figures 5 and 6 are an elevation and a vertical section respectively
of the plug of the upper cone cock; figure 7 is a side elevation of the top cylinder
cover. Similar letters in all the figures represent similar parts.
a, is the cylinder the capacity of which is almost equivalent to the maximum
quantity the tap is to the measure; b, is the cylinder-base cap and c, is the two-way
cone cock in the same, d, and e, representing the ways or passages; f, is the hollow

page_text: bottom part of the cone cock c, extending outwards below the casing, and forming
the spout for the liquid drawn off; g, is the casting fixed to the outside of the
spout, which casting serves as a washer and handle to turn the tap by; h, is a
plate on the cylinder a, marked with suitable words, letters, figures or the like and
serving to indicate the positions to which the handle must be moved in order to
draw off the required measured quantities of liquid; i, is the connection for the
lower part of the barrel or vessel containing the liquid to be measured the said
connection being formed on the base cap b, of the cylinder a; j, and k, are the
pipes extending up to any desired height within the cylinder from the base cap b,
and l, and m, are the ports in the cap b, to which the said pipes are connected
which cap forms the casing of the two-way cone cock c; n, is a third port in the
casing cover b; the passage d, in the cone cock c, can by moving the handle g, be
brought into communication with any one of the ports l, m, and n; the two pipes j
and k, of different height with their ports and m, allow only such portion of the
liquid to be withdrawn from the cylinder (and thereby measured) as is contained
in either of the spaces between the upper ends of the pipes jor k, and the top of
the cylinder, whilst the port n, allows of the whole of the contents of the cylinder
being withdrawn and thereby measured; o and 2, are the passages in the cone
cock c, set apart the same distance as the ports land m, and communicating with
the latter when the cylinder is being filled for the purpose of insuring the liquid
filling the tubes ;, and k; q, is the reduced upward extension or rod of the cone
cock c, and r, is the one-way cone cock in the top cylinder cover 8, forming the
casing of the said cone cock, a¹, representing the way or passage formed therein
which is always in communication with the interior of the cylinder a; t, is a notch
or groove in the cone cock r, in which the upper end of the rod q, engages whereby
the cone cock r, is caused to rotate with the lower cone cock c; u, is the pipe
extending from the casing s, and forming a connection with the air space in the
barrel or vessel containing the liquid to be measured; v, w and x, are the air holes
in the casing 8, of the cone cock r, made at _distances apart corresponding to the
ports 1, m and n, in the casing, b, of the lower cone cock c; y, is the upward
extension of the cone cock r, which extension can be adapted to actuate an
indicator or counter of suitable construction (not shewn in the drawing); z, is the
cover of the casing s, and 61, is a spring for keeping the cocks r and c, in position
and at the same time allowing them a certain amount of ease in action; c¹, is a ball
valve which I sometimes find it advantageous to apply to the pipe u, as shewn in
the drawing (or in any other suitable position) the ball being of material of a less
specific gravity than the liquid to be measured so that as the said liquid enters the
pipe u, when the cylinder a, has become full the ball will float and close the pipe
and thereby prevent the liquid rising therein; d¹, d', are stops for limiting the
movement of the handle g.
The operation of the tap is as follows:-
The tap in its normal condition (that is to say when it is in the position shewn
in figure 2) is closed in which position the passage or way e, in the lower two-way
cone cock c, is in direct communication with the lower connection i, from the barrel
or other vessel containing the supply of liquid to be measured, and the cylinder
or chamber a, will be filled from the said barrel or other vessel, the passage d,
being closed. The passage a¹, in the top cone cock 7, is now in communication
with the pipe u, forming the upper connection of the barrel the air which was in
the cylinder a, being forced up this pipe by the liquid as it enters the cylinder.
When the valve c¹, is used the liquid in rising will float the ball thereof so as to
close the valve and prevent the liquid rising any higher in the pipe u.
To open the tap in order to draw off a measured quantity say for example the
smallest measured quantity of the liquid, the handle g, is moved from the position
shewn in figure 2, to that shewn in figures 1 and 3, that is to say, it is brought
opposite the first division on the plate h.
As the handle g, is moved into the said position both the connections and u,
from the barrel will be first simultaneously cut off as the passages e and a¹, will be

page_text: brought against the faces of the casings b and s, and then the outlet passage d, in
the lower cone cock c, (which passage is connected to the hollow spout f) will be
brought in communication with the first port l, in the casing b, the said port being
connected to the longest pipe j, in the cylinder a, at the same time the passage a¹,
in the top cone cock r, will be brought in communication with the first opening v,
in the casing 8. The liquid now being in connection with the spout f, on the
lower cone cock c, and also with the outer air through the top cone cock r, it will
run out of the cylinder a, until the liquid comes to the level of the top of the first
pipe, and the required measured quantity of liquid. will in this manner have been
drawn off; the handle g, is then moved back so as to bring the cocks c and r, into
their former position as shewn in figure 2 and the cylinder a, will again become
full; if it be now required to draw off the next largest measured quantity of
liquid, the handle must be moved opposite the second division on the plate h, when
the passage d, will be brought in communication with the port m, and pipe k, and
the passage a¹, will be opposite the second air opening w, in the casing 8, and the
liquid will run out of the cylinder until it reaches the level of the top of the pipe k.
It will be obvious that the cylinder being full, if the handle g, be moved from the
position shewn in figure 2, to the third division on the plate h, the whole of the
contents of the cylinder will be drawn off. It will thus be obvious that according
to the size of the cylinder a, the number of pipes and the various lengths of the
same, any varying quantities may be drawn from one measure.
It will also be obvious that the said pipes can be made telescopic so as to allow
of their being adjusted according to the quantity of liquid to be drawn off.
I have not shewn in the drawings an indicator or counter applied to my improved
tap as it will be obvious that this may be of any suitable construction and it will
be easily understood without further description in what manner the said indicator
or counter can be operated by the tap. Further the said indicator or counter
would not always be required and in such cases I dispense with its use.
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. In a tap for measuring the quantity of liquid passed through it the com-
bination with a cylinder or vessel of known capacity and provided with internal
pipes of known suitable heights of a lower and an upper cock so constructed and
arranged that when the same are operated the cylinder or vessel will be filled
and the required measured quantities be withdrawn therefrom as herein before
described.
2. The combination with a tap for measuring the quantity of liquid passed
through it the tap being constructed and arranged in the manner claimed in
claim 1, of a suitable indicator or counter substantially as and for the purposes
herein before described.
3. The combination of parts forming the improved tap for measuring and
registering the quantity of liquid passed therethrough as hereinbefore described
and represented in the accompanying drawings.
