page_text: LETTERS PATENT to Benjamin Baillic, of 118, Wardour Street,
Soho, in the County of Middlesex, for the Invention of "IMPROVE-
MENTS IN APPARATUS FOR DRAWING OFF AND REGISTERING THE FLOW
OF FLUIDS."
Sealed the 14th January 1853, and dated the 6th November 1852.
PROVISIONAL SPECIFICATION left by the said Benjamin Baillie
at the Office of the Commissioners of Patents, with his Petition,
on the 6th November 1859.
I, BENJAMIN BAILLIE, of 118, Wardour Street, Soho, in the County
of Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR DRAWING OFF AND REGISTERING THE
FLOW OF FLUIDS" to be as follows:-
This Invention consists of a combination of mechanical parts, which
act as follows:-The liquid to be drawn off, and the flow of which is
to be registered, being in a suitable vessel, it is drawn off therefrom by
a syphon. On the discharging limb of the syphon is a stop cock within
the box or meter; there is also a valve acted on by a lever and float,
by which the flow of fluid is stopped, except at the time of drawing

page_text: off. The fluid from the syphon flows into a hopper or vessel connected
to the case of the measuring wheel, which measuring wheel consists of
a cylinder with several tangential blades. At the lower part of the
case of the measuring wheel is an outlet having a cock therein, by
which the flow can be stopped when it is desired to clean the apparatus,
or by which the flow of liquid from the case can be regulated. The
liquid flows from the wheel case into a vessel in which there is a float
acting on the lever, which communicates with the valve by which the
flow of fluid into the measuring wheel case is shut off, and from this
vessel the fluid is drawn off by a suitable cock or tap. There is a
separate outlet from the case of the measuring wheel when the interior
is to be cleansed. From the axis of the measuring wheel motion is
communicated to counting or recording apparatus, which may be
graduated, to indicate small or large measures of fluid, according as
the apparatus is intended for one fluid or another, there being also a
dial or dials indicating at all times the quantities which have passed,
and there may be moveable points to mark at any time the condition
in which the apparatus was left, so that no fluid can be drawn off
in the absence of parties without the fact and the quantity being
indicated.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Benjamin Baillie in the Great Seal Patent Office
on the 5th May 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
BENJAMIN BAILLIE, of 118, Wardour Street, Soho, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of November, in the year
of our Lord One thousand eight hundred and fifty-two, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Benjamin Baillie, Her special licence
that I, the said Benjamin Baillic, my executors, administrators, and

assigns, or such others as I, the said Benjamin Baillic, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time. and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands,, and Isle of Man, an Invention for "IMPROVEMENTS
IN APPARATUS FOR DRAWING OFF AND REGISTERING THE FLOW OF FLUIDS,"
upon the condition (amongst others) that I, the said Benjamin Baillie,
by an instrument in writing under my hand and seal, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be
filed in the Great Scal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
•
NOW KNOW YE, that I, the said Benjamin Baillic, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say): .
>>
This Invention consists of a combination of mechanical parts, which
act as follows:-The liquid to be drawn off, and the flow of which is to
be registered, being in a suitable vessel, it is drawn off therefrom by a
syphon. On the discharging limb of, the syphon is a stop cock within
the box or ineter; there is also a valve acted on by a lever and float, by
which the flow of fluid is stopped, except at the time of drawing off.
The fluid from the syphon flows into a hopper or vessel connected to
the case of the measuring wheel, which measuring wheel consists of a
cylinder with several tangential blades. At the lower part of the case
of the measuring wheel is an outlet having a cock by which the flow
can be stopped when it is desired to clean the apparatus, or by which
the flow of liquid from the case can be regulated. The liquid flows
from the wheel case into a vessel in which there is a float acting on the
lever, which communicates with the valve by which the flow of fluid
into the measuring wheel case is shut off, and from this vessel the fluid
is drawn off by a suitable cock or tap. There is a separate outlet from
the case of the measuring wheel when the interior is to be cleansed.
From the axis of the measuring wheel motion is communicated to

page_text: the fact and the quantity being indicated.
EXPLANATION OF DRAWING.
Figure 1. A, a cask containing a liquid fluid (drawn to miniature
scale), and which is being drawn off by the syphon B. The lower limb
will be attached to the pipe C, drawn full size. Unscrew the nipple X,
and insert a bent pipe, with which extract the air in the syphon; the
fluid will then flow through the stop cock V, and ball valve E, through
the orifice D; this valve being open e, e, the fluid will fall into the
upper cistern F, and flowing over the partition. f, will flow over and
down the pipe G, into and upon the bucket wheel or drum H, forcing
it round. The quantity passing thro' being registered by means of clock
work attached to the axle thereof at N, will flow out at the regulating
tap I, into the lower cistern J, under the float K, down the pipe L, and
through the open cock M, and will continue to flow and register until
the cock M, is shut, when the fluid will immediately rise in the cistern
J, force the float K upwards, close the valve e, e, and stop the flow of
the fluid until the cock at M is reopened, when the float K will im-
mediately fall, and opening the ball valve e, e, will supply the meter as
before. To clean out the metre, stop off the supply by turning the stop
cock V, draw off all the contents by the cock T, unscrew the nipples
W, and X, and insert a small funnel into the pipe at X; hot water
can then be poured through the metre until it is effectually cleansed
from all sediment

page_text: of ever varying height of fall, as in casks of licensed victuallers; and,
secondly, an effective method of regulating the speed of the wheel, in
order to obtain a correct registration of the quantities passing through
the metre.
I obtain the first by using the syphon, as shewn, Fig. 1, B. By this
method the fluid must always fall from one height, whatever may be
the quantity in the cask, flowing as it must over the top of the cask or
vessel. This is assisted by the stop cock V, lessening the quantity
passing through, if required; and, further, by the ball valve E, de-
livering the fluid, not at once, into the wheel or drum F, but into the
cistern F, and passing it over the partition f, before it flows over and
down the pipe G, which now becomes the true height of fall upon it.
To overcome the second difficulty, viz., to regulate the speed of the
wheel or drum, I effect this by using what I denominate a regulating
tap, as shown, Fig. 2, I, side elevation or profile; and Figure 3, 1,
end or front elevation.
The tap is shown turned up to its greatest elevation, retaining in the
metre the maximum of fluid of which it is capable, and minimum of
speed. In order to increase the speed, should it be found that the metre
registers less than it delivers, turn the tap to the right hand by the key
O, the fluid will lower from Y, down to any given point to Z. Gradually
diminishing the resistance, and the weight or pressure on the wheel
being still the same, the speed will be, of course, increased in proportion
as the resistance is diminished.
Dials. Figure 5, represents a dial peculiarly adapted for registering
the delivery of small quantities, and also indicating the decrease of
stock in each cask or vessel. The inner circle is divided into 32 parts
or quarterns, and the short pointer moves once round the circle for
every gallon delivered, registering the small quantities as delivered.
The outer circle is divided into one hundred parts, and for every
revolution of the short pointer the long one moves over one division.
On this dial are two circular grooves, under cut, in which two small
pieces of steel wire are inserted, or as it is turned, snapped into the
grooves; on these wires are fixed two small pointed plates forming
indicators. These moveable points, marked A, and B, can be placed

page_text: immediately opposite the short and long pointers, so that no fluid can
be drawn off in the absence of parties without the fact and the quantity
being indicated.
I would further remark, that the preceding description applies to my
apparatus when used for indicating the delivery of small quantities;
when it is intended to be used as a water metre, and consequently
subject to very high pressure, I make use of an additional compart-
ment directly over and forming part of the case of metre. This is
supplied from the main through a ball cock, and the water will be
<delivered into the metre through a syphon, as before described.
Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that I make
no claim to the several parts herein described, nor do I confine myself
to the precise details. But what I claim is the mode herein described
of combining apparatus for drawing off and registering the flow of
fluids.
In witness whereof, I, the said Benjamin Baillie, have hereunto
set my hand and scal, this Twenty-ninth day of April, in the
year of our Lord One thousand eight hundred and fifty-three.
Witness,
H. W. CARPMAEL.
