We make use of a cylinder with piston, and with inlet ports at each end,
we connect to these ports two pipes or chambers communicating at top and
bottom with the inlet and the outlet pipe and so arranged as to contain 4
seatings for 2 equilibrium valves, one such in each pipe.
These valves may
each have a facing of metal, or be faced with leather, India rubber or any other
suitable material. These valves move by a falling weight on an arm or lever so
arranged as to be tipped over by being connected with the piston rod at the end
of each in and out stroke. We provide a horizontal shaft on which we mount a
lever or plate having 2 snugs for the weight arm or lever to fall upon which
moves both valves at each stroke so as to admit the fluid on one side of the piston
and to let it discharge from the other side of the piston. The weight lever and the
snug plate are both loose on the shaft; but on the same shaft we fix a half snug
plate by a set screw or key so that a small moving rod connected with the shaft
will tip the weight on the lever arm over each way: on the small rod 2 pins are
fixed to regulate the tip at any distance of travel required by the piston. The
small rod is moved by a boss on the piston rod having also a hole on the side for
guiding the small rod containing the pins. to slide up and down through.
The piston travel is limited or regulated by suitable stops adjustable or not for
instance by a screw through, each end cover..

We make use of a cylinder with piston, and with inlet ports at each end, we
connect to these ports two pipes or chambers communicating at top and bottom
with the inlet and the outlet pipe and so arranged as to contain four seatings for
two double seated valves of a form somewhat similar to the so called equilibrium
valves, one such double seated valve in each pipe. These valves may have facings
of metal or be faced with leather, india rubber, or any other suitable material.
These valves move by a falling weight on an arm or lever, so arranged as to be
tipped over at the end of each in and outstroke, by being connected with the piston
rod We provide a horizontal shaft on which we mount a lever or plate having
two snugs for the weight arm or lever to fall upon which moves both valves at
each stroke so as to admit the fluid on one side of the piston and to let it discharge
from the other side of the piston (or vice versa the weight lever may be provided
with such snugs) The weight lever and the snug plate are both loose on the
shaft but on the same shaft.we fix a half snug plate, by a set screw or key, so
that a small moving rod connected with the shaft will tip the weight on the lever
Farm over each way; on the small rod two pins are fixed to regulate the tip at any
distance of travel required for the piston. The small rod is moved by a boss on
the piston rod, having also a hole on the side for guiding the small rod containing
the pins to slide up and down through.
The pistons travel may furthermore be limited or regulated by suitable stops
adjustable or not for instance by a screw through each end cover.
In order that our Invention may be more fully understood we will now proceed
to describe the same with reference to the accompanying drawings. Figure 1 is a
plan of a machine or apparatus constructed according to our Invention for measuring
water and other fluids. Figure 2 is a vertical section through the line A, B of
Figure 1 showing the arrangement of valves. Figure 3 is a vertical section
through the line C, D, of Figure 1 showing the measuring cylinder and the tappet
action for shifting the valves.
Similar letters of reference refer to like parts in all the Figures. A is the
measuring cylinder M is the piston. K is the port at bottom of cylinder and L the
port at top of cylinder; B B B and B are the double sentod valves; C is the
beam or lever connected to and operating the inlet valve and D is the weight for
closing the valve. H is the horizontal shaft on which the arm carrying the
weight D and the beam are mounted loosely; G is a pinion keyed upon the
horizontal shaft H; and F a rack gearing into the pinion G, the said rack being
operated as hereafter more fully described by means of the up and down movement
of the piston rod; M' is the piston rod; N is an arm on the top of this piston rod
forming part of the tappet action; O is a rod in one with the rack F and passing
through the arm N; PP are collars or tappets on the rod O the position of which
collars may be varied on the said rod according to the length of the stroke of the
piston required; E is a bell crank plate or lever (keyed on the shaft H) the ends.
of which extend a sufficient distance to come under one of the projections or lugs R
on the weight lever and serve to lift. the weight D on the return stroke of the
piston; S, S', a e flat springs attached to the side of the valve boxes for keeping

page_text: the valve tight after the weight is lifted off same, one of the inclined planes D' on
the weight arm D in falling forces the spring out of the way to allow the valve to
close. I is the inlet and X the exit for the water or other fluid.
The operation of the machine is as follows:-
The water or other fluid is admitted by the inlet pipe I to the cylinder A, say by
the port K, the valve B¹ being open to allow the fluid to pass by that port into the
cylinder A; In Figure 3 'the piston M, is shewn at the top of its stroke with the
valve B' open, see figure 2. The entry of the water or other fluid to the cylinder
having caused the piston to rise to the point at which it is shown and this forces
the water or other fluid above the piston through.the port L, and thence by the
valve B to the outlet X and empties the cylinder of its contents above the piston,
now as the piston M thus ascends in the cylinder the arm N on the top of the
piston rod acts on the uppermost collar or tappet P which operating the rack F
rotates the pinion G on the shaft H and the upper arm of the bell crank lever E
turning with the shaft H and coming into contact with the corresponding snug or
projection R lifts and tilts or tips it over until the weight D falls on the lever C
which is connected by a joint pin to the valve rod of the double valve B². B¹ thereby
closing the valve B' and opening the valve B2 the pressure of the water will then
close the valve B and open the valve B³ the stroke of the piston is at the same
time reversed and the reverse operation takes place and so on continuously and
alternatively so long as the machine is at work. The springs 'S and S¹ keep the
valve B tightly on its seat when the lever C is up. The lower arm of the bell
crank lever E returns the weight arm D to its opposite position in the down stroke
of the piston by coming in contact with the other snug R on the lever D. We do
not limit ourselves to the particular apparatus or machinery here shown for
operating the double valves although we have found in practice the arrangement
we have described to answer well. We may for instance operate both the double
valves by suitable connections.
Having now described the nature of our said Invention and in what manner the
same is to be performed We declare that We claim
First In apparatus for measuring water and other fluids and applicable as a
motive power engine the employment of double seated valves to regulate and
govern the measuring or motive power thereof the said valves being arranged and
operated substantially as hereinbefore described
Second-The particular construction and arrangement of apparatus for measuring
water and other fluids and also applicable as a motive power engine substantially
as hereinbefore described with reference to the accompanying drawings.
In witness whereof we the said William Hamer and Cobden Willie Bright
Hamer have hereunto set our hands and seals this third day of April in
the year of our Lord one thousand eight hundred and eighty-three.
