WRIGHT JONES, of Manchester, in the County of Lancaster, Engineer. "IMPROVE-
MENTS IN METERS FOR MEASURING WATER AND OTHER LIQUIDS.".
My Invention relates to meters for measuring water and other liquids, and
consists in arrangements whereby I secure greater accuracy of measurement and
economy of construction than hitherto accomplished.
The first part of my Invention consists in the employment of a cylinder
provided with inlet and exit ports, within which are two pistons capable of sliding
therein by pressure of the liquid to be measured, these pistons I connect by means
of a rod. Within the above named cylinder and between the before named pistons
I mount a lever turning upon a stud carried by the cylinder. One end of the
aforesaid lever is formed as a jaw so as to act upon a slide valve, by which the
admission and exit of the water to and from the cylinder is controlled. The other
end of the before named lever is provided with projections, against which the
aforesaid pistons strike as they traverse to and fro in the cylinder so as to turn the
said lever upon its stud. The aforesaid lever I also provide with inclined surfaces,
against which a bowle is forced by means of a spring.
When either of the before named pistons come in contact with the aforesaid lever,
it is thereby caused to turn upon its centre, and one of its inclines, acting upon the
previously mentioned bowle, compresses the before named spring, but on a further
movement of the lever the spring acting upon the other incline causes a further
turning of the lever, thereby effecting a movement of the slide valve, and thereby
causing the pistons to move in an opposite direction until they again act upon the
aforesaid lever and move the slide valve. The aforesaid lever actuated by the
piston I connect to a registering dial, by which the movements of the piston will
be' recorded.
The second part of my Invention consists in the employment of a cylinder
provided with inlet and exit ports, within which cylinder I place a piston so as to
be capable of sliding from end to end thereof by the pressure of the liquid being
measured.
Within the aforesaid cylinder I mount shafts, one end of such shafts passing
through stuffing boxes into a valve box or chamber formed upon the outside of
the above named cylinder.

page_text: The aforesaid shafts are provided with arms, against which the said piston acts
in its passage from end to end of the cylinder. Upon the ends of the previously
mentioned shafts within the valve box or chamber are mounted levers, to which a
rod is jointed at its ends, and by which they are connected. Upon this rod are
projecting parts embracing a lever mounted upon a cross shaft carried in brackets
secured to the valve box. Upon the previously mentioned cross shaft is mounted a
lever, the outer end of which is formed as a jaw, embracing a projection formed upon
a slide valve, by which the inlet and exit of the liquid to be measured by the piston
and cylinder is controlled. Upon the lever carried by the before named cross
shaft and acted upon by the aforesaid connecting rod, I mount a bowle, against
which is a double incline forced forward by a spring. When the aforesaid piston
arrives in contact with one or other of the arms upon the above named shafts,
a turning thereof will be effected, which will cause the rod within the valve box to
turn the lever carrying the bowle, thereby causing it to force back the double
incline, such movement compressing the spring acting upon the said incline, until
the bowle has arrived at the highest part thereof, when the spring acting through
the medium of the other portion of the incline will cause the aforesaid lever to be
still further turned. This movement acting through the lever mounted upon the
above named cross shaft and embracing the slide valve, will cause the said valve to
be traversed and thereby the before named piston will be caused to move in an
opposite direction until it arrives against the lever at the opposite end of the
cylinder, when the slide valve will be again traversed.
The cross shaft above named I connect to a dial, by which the movements of the
aforesaid piston may be recorded.

The third, part of my Invention relates to the cylinders used in meters for
measuring water and other liquids, and consists in casting therein a lining or
coating of metal or alloy, not readily corroded by the liquid to be measured; such
lining after being cast I afterwards finish by boring, turning, or .by other suitable
means.
The next part of my Invention consists in forming the ports or passages in
water meters without curves or bends, the same being closed by caps attached by
screws, whereby I am enabled to more readily clean such ports or passages
aforesaid, should they become choked or stopped.
