Year: 1875

page_text: LETTERS PATENT to Joseph Quick, junior, and James William Restler,
of Great George Street, Westminster, in the County of Middlesex,
for the Invention of "IMPROVEMENTS IN METERS FOR MEASURING
LIQUIDS."
PROVISIONAL SPECIFICATION left by the said Joseph Quick and
James William Restler at the Office of the Commissioners of
Patents, with their Petition, on the 25th February 1875.
We, JOSEPH QUICK, junior, and JAMES WILLIAM RESTLER, of Great
George Street, Westminster, in the County of Middlesex, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN METERS
FOR MEASURING LIQUIDS," to be as follows:-

page_text: acting in their travel alternately against one or more slide valves fitted
in a partition to cover and uncover the inlet and outlet ports automa-
tically for the passage of the liquid in the proper direction, the move,
ment of the pistons or of the valves actuating the registering apparatus
which indicates upon dials the number of times the pistons have moved,
and consequently the quantity of water passed through the apparatus.
The outer casing of our apparatus is partly cylindrical and partly D
shaped. In the cylindrical parts we arrange pistons (packed as usual to
make them water tight), these being connected on their inner faces by a
rod which is free to move in a partition, the length of which determines
the distance the piston shall travel to and fro.
'
The top half of the partition has a double valve fitted in it, this being
free to be moved end on by the pistons as they alternately come into
contact with it, which they do by the pressure of the inflowing liquid.
The valve is tubular and has ring projections upon its exterior, between
which passages are formed for leading the liquid into and from the
inside according to the position for the inlet or the outlet. The valve
works within a kind of box, also formed with passages or ports between
rings upon its exterior, one port being always open to the supply and
one for each piston being always open to the outlet from the casing.
The box moves to and fro under the action of the valve, when the water
admitted by the valve acts upon the area of the valve and box the two,
that is the valve and the box, then moving together. The box is limited
in its travel by stops fitted in the casing. The valve is so fitted that
the first movement by the piston puts one of its rings over and past the
inlet port from the supply; the water then acts against a division plate
of the valve, and under that pressure it continues its motion until its
outer ring presses against the cap on the end of the box, when they
both travel together as one, the box shutting up one port which leads
from the outer face of, say, No. 1 piston, and the valve another port,
which leads from the inner face of, say, No. 2 piston, the valve at the
same time opening a port for the supply to go to the inner face of No. 1
piston, and the box also to the outer face of No. 2 piston, both pistons
being acted upon by pressure upon the outer and inner faces alternately
to move them over.
In some cases we fit a ringed sliding valve (not tubular) within, say,
the top half of the partition and a ringed tubular sliding valve within, say,
the lower half of the partition, and arrange inlet and outlet passages in

page_text: the partition for the liquid to pass from one valve to the other. The
first of these valves is in equilibrium, and when the second valve is
pushed along by the action of the piston from one side a portion of the
water from the inlet port of the tubular valve passes to the back of the
equilibrium valve, the pressure from the opposite end having by the
time been removed, consequently the equilibrium valve is moved over,
whereby a closed outlet port is opened on one side and an open outlet
port is closed on the other side, the action being alternate and put.
in force by the movements of the tubular valve under the action of
the pistons.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Quick and James William Restler in the
Great Seal Patent Office on the 25th August 1875.

condition (amongst others) that we, the said Joseph Quick, junior, and
James William Restler, or one of us, our executors or administrators, by
an instrument in writing under our, or one of our, 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,

page_text: 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 we, the said Joseph Quick, junior, and James
William Restler, do hereby declare the nature of our 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,
reference being had to the Drawings hereunto annexed, that is to
say:―
This Invention relates to improvements in meters for measuring
liquids.
According to our Invention two pistons connected by a rod are caused
to travel to and fro under the action of inflowing liquid or fluid, the
pistons acting in their travel alternately against one or more slide valves
fitted in a partition to cover and uncover the inlet and outlet ports
automatically for the passage of the liquid in the proper direction, the
movement of the pistons or of the valves actuating the registering
apparatus which indicates upon dials the number of times the pistons
have moved, and consequently the quantity of water passed through the
apparatus.
The outer casing of our apparatus is partly cylindrical and partly
shaped. In the cylindrical parts we arrange pistons (packed as usual to
make them water tight), these being connected on their inner faces by a
rod which is free to move in a partition, the length of which determines
the distance the pistons shall travel to and fro.
The top half of the partition has a double valve fitted in it, this being
free to be moved "end on" by the pistons as they alternately come into
contact with it, which they do by the pressure of the inflowing liquid. The
inner valve is tubular and has ring projections upon the exterior, between
which passages are formed for leading the liquid or fluid into and from
the inside according to the position for the inlet or the outlet. The valve
works within a kind of box, also formed with passages or ports between
rings upon its exterior, one port being always open to the supply, and
one for each piston being always open to the outlet from the casing.
The box moves to and fro under the action of the water admitted by the
inner valve, which acts upon the area of the valve and box, the two,
that is the valve and the box, then moving together. The box is limited

page_text: in its travel by stops fitted in the casing. The inner valve is so fitted
that the first movement by the piston puts one of its rings over and past
the inlet from the supply; the water then acts against a division plate
of the valve, and under that pressure it continues its motion until its
outer ring presses against the cap on the end of the box, when they
both travel together as one, the box shutting up one port which leads
from the outer face of, say, No. 1 piston, and another port which leads
from the inner face of, say, No. 2 piston, at the same time opening a
port for the supply to go to the inner face of No. 1 piston, and the box
also to the outer face of No. 2 piston, both pistons being acted upon by
pressure upon the outer and inner faces alternately to move them over.
In some cases we fit a ringed sliding valve (not tubular) within, say, the
top half of the partition, and a ringed tubular sliding valve within, say,
the lower half of the partition, and arrange inlet and outlet passages in
the partition for the liquid to pass from one valve to the other. The
first of these valves is an equilibrium, and when the second valve is
pushed along by the action of the piston from one side a portion of the
water from the inlet port of the tubular valve passes to the back of the
equilibrium valve, the pressure from the opposite end having by this
time been removed, consequently the equilibrium valve is moved over,
whereby a closed outlet port is opened on one side and an open outlet
port is closed on the other side, the action being alternate and put
in force by the movements of the tubular valve under the action of
the pistons.
Also in some cases we fit in the partition two valves, the one smaller
than the other, the larger of which works works independently of the
pistons, but under the alternate admission and release of the fluid acting
upon its ends. The motion of this valve, and consequently the flow of
fluid to and from the measuring cylinders, is governed by the smaller
valve, which is acted upon by the pistons. In this case the larger valve
instead of being connected only with the ports leading to the outer ends
of the cylinders is connected to the inner ends also by extending the
port from the outside of, say, No. 1 piston to the inside of No. 2, and
from the outside of No. 2 piston to the inside of No. 1.
In this case
the body of the meter is made cylindrical for its whole length.
On Sheet 1 Figure 1 is an elevation; Figure 2, a longitudinal section;
Figure 3, an end view; and Figure 4, a cross section of a meter arranged

page_text: with two tubular valves. In these Figures A, A, are the cylinders in
which the ports B', B2, are cast leading to the ends of the cylinders,
also the inlet port C and the outlet ports D, D. The opening and closing
of the port B', B², being governed by the valve E, in which the inlet
port F and the outlet ports G, G, for the inner valve H are cut. The
length of the travel of this valve is limited by the caps I, I, and of the outer
valve E by the stops K, K, upon the piston rod M; the two pistons L', L³,
are fastened, working water-tight in the cylinders A, A. Upon admitting
fluid to the apparatus by the pipe N it passes to the valve through the
port C, and thus to the end of the cylinder through the port B', and
acts upon the outer face of the piston L'; it also passes into and
through the inner valve through the port F, and acts upon the inner
face of the piston L³, thus causing them to move in the direction shown
by the arrow until the division O in the inner valve H is moved past
the port F, when the pressure passes through this valve and acts upon
the opposite side of the piston L', and the inner side of the piston L*
being now open to the outlet through the port G, the pressure upon the
area of the ends of the valves is reversed, thus causing them to move
until stopped by the ring K, and the rings on the outer valve having
passed the ports B'; B³, the pressure upon the outer faces of the pistons
is reversed also.
On Sheet 2 Figure 1 is an elevation; Figure 2, a longitudinal section;
Figure 3, a cross section; and Figure 4 an end view of a meter with
one piston and one tubular valve. In these Figures A, A, are cylinders in
which the ports B¹, B³, are formed leading to the outsides of both pistons.
In, say, the upper valve box, the ends of which are closed by plates, a
piston valve C is fitted which regulates the flow of fluid to and from
the outer ends of each cylinder by means of the inlet port D and the
outlet ports E, E. In, say, the lower valve box a tubular valve F is
fitted which governs the flow to and from the inner side of each piston
by means of the inlet port G and the outlet ports H, H, and also admits
and releases the fluid for moving the piston valve by means of the two
ports I', I, which are formed in the casing and lead from this valve box
to each end of the piston valve case. In each cylinder a piston K', K³,
is fitted water-tight, both of which are fastened to the rod L. Upon 3
admitting fluid to the meter by the pipe N it passes to the piston valve
through the port D, and thence by means of the port B' to the outer
side of the piston K', and to the tubular valve through the port G, and

page_text: Upon the piston K¹
pushed over until the
thence through the tube in it to the inner side of the piston K*; it also
passes up the port I' and acts upon the end of the piston valve to keep
it in position. The outlet from the inner side of the piston K¹ is also
open through the tube of the lower valve, and thence through the
outlet port H; it is also open from the outer side of the piston K³
through the port B and the outlet port E.
nearing the end of its stroke the valve F is
division plate has passed the inlet port G, the pressure passes down
the opposite tube and thus acts upon the inner side of the piston K',
and also upon the end of the piston valve by means of the port I; the
pressure upon the opposite end having been relieved by means of the
port I¹ the piston valve is moved over by the pressure of the fluid until
stopped by the cover. Thus the pressure from the inlet port D passes
up the port B2 to the outer face of the piston K³, whilst the outlet from
the outside end of the piston K' is open through the port B' and the
outlet port E. The outlet from the inner side of the piston K² is also
open through the tube in the valve and the port H.
On Sheet 3 Figure 1 is a longitudinal section; Figure 2, a cross
section; Figure 3 an elevation; and Figure 4 an end view of a meter
with two piston valves. In these Figures A, A, is a cylinder in which
a bush B is tightly driven, and in which the two valves are placed. The
smaller one C communicates with the ends of the larger one by means
of the ports D¹, D³, and the passages formed in the plates which cover
water-tight the ends of the main valve box. In the cylinder the
ports G, G, are made each connecting a port in the main valve box
with the outside end of one cylinder and the inner end of the opposite
one. In the main valve box the inlet port is formed at I, and the
outlet at K, K², in the small valve box the inlet is at L and the outlets
at M; M. In each cylinder a water-tight piston S1, S2, is fitted, both of
which are fastened at opposite ends to the rod N. Motion is commu-
nicated to the registering apparatus in the box O by the spindle P,
which motion is taken from that of either the pistons or valves. Upon
admitting fluid to the meter by the pipe R it passes into the small valve
through the port L, and thence through the port D and the passage F
in the cover to the end of the piston valve, the opposite end of which is
open to the outlet through the passage F, the port D², and the outlet
port M. The fluid to the cylinders passes through the port I to the
main valve, and thence through the port G³ to the outer face of the

page_text: piston S and the inner face of the piston S¹. The outlet from the
outer face of the piston 81 and the inner face of the piston 82 passing
through the port G¹ and the outlet port K'. Upon the pistons nearing
the completion of the stroke the piston 83 pushes the small valve C by
- means of its projecting stem until the ring formed on the centre of its
-length passes the port L, when the pressure upon the ends of the main
valve is reversed, thus causing it to move over under the action of the
inflowing fluid until stopped by the cover plate E, and by this means
reversing the action of the pistons in the measuring cylinders.
