IMPROVE- MENTS IN APPARATUS FOR MEASURING WATER AND OTHER LIQUIDS
Year: 1864

page_text: LETTERS PATENT to Walter Payton, of Bedford Place, Commercial Road,
in the County of Middlesex, Gun Maker, for the Invention of "IMPROVE-
MENTS IN APPARATUS FOR MEASURING WATER AND OTHER LIQUIDS."
PROVISIONAL SPECIFICATION left by the said Walter Payton at the
Office of the Commissioners of Patents, with his Petition, on the 16th
April 1864.
I, WALTER PAYTON, of Bedford Place, Commercial Road, in the County of
Middlesex, Gun Maker, do hereby declare the nature of the said. Invention
for "IMPROVEMENTS IN APPARATUS FOR MEASURING WATER AND OTHER LIQUIDS,"
to be as follows:-
The liquid to be measured is admitted alternately through opposite sides of a
partition applied across an annular measuring chamber, where it acts on a piston
in that chamber, and causes it to move therein in opposite directions alternately
to and from the opposite sides of the partition, which acts as an abutment for
the liquid, to enable it to set the piston in motion. The liquid flowing into
the annular chamber from one side of this abutment having acted to drive the
piston to the desired extent in one direction is then caused to flow through the
opposite side of the abutment, whilst the liquid that has been flowing in
passes away for use or otherwise.
The valvular arrangement I prefer to use consists of a cylinder divided
transversely by a partition into two parts, one of which is connected with the

page_text: source of supply, and serves to conduct the liquid into the annular chamber to
be measured, whilst the other part serves to conduct the liquid after measure-
ment for use, there being openings in each of the parts of this cylinder capable
of being brought alternately opposite corresponding openings in the two sides
of the abutment.
In place of a cylindrical valve a valve of other form may be employed, and
I give motion to it, as required, by the piston alternately acting on the opposite
and adjustable ends of a sliding bar or rod having weighted or spring con-
nection, by which to give the requisite sensitiveness to the motion of the
valve, and at the same time to actuate indicating apparatus.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Walter Payton in the Great Seal, Patent Office on the
15th October 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WALTER
PAYTON, of Bedford, Place, Commercial Road, in the County of Middlesex,
Gun Maker, send greeting.
.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of April, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Walter Payton, Her special licence that I, the said Walter Payton, my
executors, administrators, and assigns, or such others as I, the said. Walter
Payton, 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
MEASURING WATER AND OTHER LIQUIDS," upon the condition (amongst others)
that I, the said Walter Payton, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, 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 Seal Patent Office within six calendar months next and immediately.
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Walter Payton, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,

page_text: to be particularly described and ascertained; in and by the following statement
thereof, that is to say :-
My improvements relate to an adaptation or combination of means by which
water or other liquid to be measured is caused to act on alternate sides of, and
thereby give motion to a piston or moveable partition contained in an annular
chamber for the purpose of measuring such liquid.
In order that the improvements. may be fully understood I will, by the aid
of the accompanying Drawings, proceed more fully to describe the same.
1:
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an internal view; Figure 2 a transverse section; Figure 3
an external side view; and Figure 4 an edge view of apparatus, arranged
according to my Invention; Figures 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16,
17, and 18 show some of the parts separately.
a is the case or frame, which is formed of two concentric cylinders a', a³,
and side plates a³, a', as shown; the plate a³ is part of the same casting with the
cylinders a, a, and the plate at is secured thereto by screw nuts to facilitate
entrance to the interior for the application or removal of the enclosed parts;
b is the pipe by which water or other liquid is conducted into the apparatus to
be measured, and c is a pipe by which the measured liquid may be drawn off;
d. is a moveable, piston, capable of moving in the annular chamber between
the two cylinders a¹, a². This piston is unconnected with the moving parts of
the apparatus, and is simply formed to move water-tight in its annular
chamber, the opposite surfaces d', d', having leather or other suitable material
applied to them, thereby effecting a hydraulic packing; e is a partition, by
which, and the moveable piston d, the annular chamber is divided into two
parts, acting as measuring chambers. This partition carries the valve f, by
which the course of the fluid is directed into and from the annular space
or compartments.. a, a, through the opposite sides of that partition. By
examining the separate views of this valve, as given full size at Figures 9, 10,
11, 12, 13, 14, and 15, it will be seen that it is divided in the direction of it's
length into two parts by the partition f', and that each part is provided with
two passages, marked respectively (2), (3.), (4), and (5), adapted to come.
opposite corresponding passages (6); (7), (8), and (9), in the partition. e;
and the passages in the cylindrical valve f are formed in relation to those in
the partition e, so that when fluid is flowing in on one side of the partition e
to act on one side of the piston d fluid will be passing away by the opposite
side of that partition. Thus, as the parts are shown, fluid entering the appa-
ratus by the pipe & will pass through the valve f by the passages (2) thereof.

page_text: and (6) in the partition e, when the partition e acting as an abutment, the
the piston d will be caused to traverse in the annular space until it arrives
near the opposite side of the partition e, and then by the cylindrical valve f
being caused to make a partial rotation, the passage (3) thereof will be
brought coincident with the passage (7) of the partition e, whilst the
passage (6) will be closed, and. the fluid will now pass in through the pas-'
sages (3) and (7) into the annular space through the opposite side of the
partition e, causing the piston d to move in the opposite direction, when the
fluid, which had passed therein by the passages (2), (6), will, by the passage
(5) being brought coincident with the passage (9) pass away through those
passages to the pipe c, and then when the valve f makes a partial rotation
back again the fluid which had passed in by the passages (3) and (7) now passes
away by the passages (4) and (8) to the pipe c, and so on alternately; e¹ is a
bar fixed to the partition e, and having a spindle e², which is, by preference,
formed of hardened steel, and pointed to pass into a conical recess formed for
it in the partition f¹ in the valve f, to bear the pressure and consequent friction
exerted upon the valve by the flow of water into the apparatus. The desired
alternating movement to the valve f is obtained in the following manner :-
The valve is formed to receive the stem g' of the cross piece 9 (shown
separately full size, by Figures 17 and 18), upon which rests one end of the
bar h, the other end of which is by pin joint connected to the slide i, to which
is affixed the weight ¹. The slide i passes through and is guided by the
fixed guides 2, 2, and the bar h passes through a slot formed in a segmental
bar j, the adjustable screws 1, 2, at the opposite ends of which are alternately
acted upon by the opposite sides of the piston d. As the parts are shown the
adjustable screw j¹ will, in the motion of the piston in the direction of the
arrow, be next acted upon when in the motion of that bar j through the par-
tition e; the end of the bar h will be slided up the cross bar g beyond a central
position, when the weight i¹ acting thereon will cause the valve to be moved
fully over so as to alter the course of the liquid passing therethrough, and
then when the piston d has traversed round to the opposite side the opposite
end of the bar j will be acted upon in like manner, and so on alternately.
Communication is made from the moving parts in the chamber a' to suitable
index apparatus, which may be such as is employed in other meter apparatus
for the purpose of indicating the quantity of fluid passing through this
measuring apparatus. In place of a cylindrical valve a valve of other form
may be employed.
Having thus described my improvements, and means which I adopt in
carrying the same into effect, I would have it understood that what I claim is

page_text: the adaptation or combination of means for effecting the measurement of
water and other liquids, whereby a piston travelling in an annular chamber
unconnected with the moving parts is caused to give motion to mechanical
arrangements, by which the opening and closing of the valve passages are
effected, substantially as explained.
In witness whereof, I, the said Walter Payton, have hereunto set my
hand and seal, this Fifteenth day of October, in the year of our Lord
One thousand eight hundred and sixty-four.
WALTER PAYTON. (LS.)
