Improvements in Water-meters.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
This invention relates to water-meters, and it consists in certain novel features of
construction, arrangement and combination of parts which will be readily understood
from the following description with reference to the accompanying drawings in which,
Figure 1 is a vertical longitudinal sectional elevation on the line 1, 1 of Figs. 2
and 3.
Figure 2 is a vertical transverse section through the outer casing and feed pipe on
line 2, 2 of Fig. 1 showing the moving parts in end elevation.
'
Figure 3 is a horizontal section on line 3, 3 on Fig. 2.
Figure 4 is a horizontal section through the feed pipe and a small part of one side
of the enclosing casing on line 4, 4 of Fig. 2, and
Figure 5 is a partial vertical longitudinal section of the oscillating cylinder on
line 5, 5 of Fig. 2.
In the drawings A is the measuring cylinder provided at the centre of its length
with the trunnions A¹ and A* the former fitting into a bearing in the central ring or
belt B while the latter is provided with a socket to receive the inner end of the
discharge pipe C which screws into a threaded bearing in the opposite side of said
ring or belt B as shown in Figs. 2 and 3.
The ring B has screwed into each side thereof a hollow cylinder B₁ baving its
outer end closed by a head formed therewith or secured thereto as may be preferred
which cylinder with said ring constitute the outer or fixed casing of the meter within
which are enclosed all the working parts of the meter, except the register, and into which
all the water flows before passing into the measuring cylinder A.
The ring B has cast therewith the inlet pipe B' on the inner end of which is formed
a valve seat a against which is fitted the double ported slide valve b secured to the
valve rod 6 extending the whole length of the cylinder A and having bearings
in ears cc projecting from the heads A' A' of said cylinder as shown in Figs. 1
and 2.
The ring B has secured to its inner surface directly opposite the pipe B and at a
distance therefrom equal to the thickness of the valve the valve seat à having formed
in opposite ends thereof two chambers d¹ and d² separated by the partition d³, and
with the two ports e and e' for the admission of water to one or the other of said
chambers according as the valve 6 is at one extreme or the other of its movement.
The chambers di and have screwed therein the pipes e and e' respectively the
outer ends of which are closed by suitable caps and are provided in their upper sides
with the discharge orifices e and e as shown in Figs. 1 and 2.
Each of the heads A' A³ of the cylinder A has cast in one piece therewith the
bent pipe a' and has formed in its inner surface the recess a³ to receive the lever a*
mounted on the horizontal shaft at extending through one side of the enclosure of
said recess and carrying on its end, outside of said head, the lever a as shown in
Figs. 1, 2 and 5.
Each of the heads A A' has formed on its outer surface the lug or shoulder a
with which the shoulder on the lever f engages to lock the cylinder at the end
which is in its most elevated position.

page_text: The levers are mounted on studs or fulcrum-pins set in the pipes e and e³ near
the outer end as shown in Figs. 2 and 4, and have set therein or formed thereon
near their upper end the laterally projecting pins or lugs f with which the levers a
engage to move the levers about their fulcrum-pins and disengage the shoulder f¹
of said levers from the lugs a' on the cylinder heads when the piston D comes in
contact with one or the other of the levers and moves it into the recess a³.
The upper ends of the levers are moved towards the heads of the cylinder and
into engagement with the lugs a by means of a counter weight f' as shown in
Fig. 5 and this movement of said lever f acting through the pins or lugs f, the
levers a and rocker shaft a' causes the levers as to be moved inward toward the
I centre of the cylinder as soon as the pressure of the piston is removed therefrom
as shown in Fig. 5.
.
The lower end of the lever a³ also engages with the arm 9 secured on the end of
the valve rod 61 when it is moved outward by the piston, and moves said rod a
sufficient distance to reverse the position of the valve b, and change the direction of
current of water entering the outer casing.
The arms are extended beyond the valve rod and have formed on their
extremities the pads gl located above the pipes e and e³ and in such positions relative
to the orifices e and that when the valve rod is at the extreme of its movement
towards the right of Figure 1 the pad g¹ at the opposite or left hand end of said rod
will be directly over the orifice e and when said rod is moved to the limit of its
stroke toward the left of Fig. 2 the pad g¹ at the right hand end of said Fig. 2 will be
over the orifice e*.
E and E are the inlet valve casings and F and F¹ the exhaust valve casing all
arranged in a row and connected together and to the curved pipes a¹ and the
trunnion A of the cylinder, by the pipes hhjjk and k¹ as shown in Fig. 1.
The inlet valve casings E and E' are open at top and bottom and have fitted
therein the valves 7 and respectively the stems of which project below the lower
ends of their casings, the valve seats being at the upper end of said casings as
shown.
The exhaust valve casings F and F have double walls m and m¹ the former
extending a short distance above the latter and has its upper end closed by the screw
cap m as shown.
The inner cylinder m¹ is open at top and bottom, and has formed on its upper end
a seat upon which the valve n or n¹ rests, the stems of said valves projecting below
their casings as shown in Fig. 1.
The inlet valve casing E and the exhaust valve casing F are connected at their
lower ends by the tie bar o and the inlet valve casing E¹ and the exhaust valve
casing F1 are in like manner connected by the tie bar o¹, said bars o and o¹ each having
formed thereon downwardly projecting ears to which are pivoted the levers o³ and o³
respectively.
The levers o³ and o* extend inward from their pivotal connection to the bars o and o¹
beneath the exhaust valves n and n' respectively and outward to same distance
beyond the inlet valves and respectively and have their outer ends fitted to
bearings in blocks p and p³ formed upon or secured to the pipes e³ and e as shown
in Fig. 1.
Said pipes and also have formed thereon or secured thereto the blocks or
lugs p2 and p respectively with which the inner ends of the lever o³ and o³ come in
contact when the end of the cylinder to which said lever is connected is depressed as
shown in Fig. 1.
The operation of this invention is as follows:
The meter being properly connected in the line of service pipe and the outer casing
and the cylinder A being filled with water with the several parts in the position
shown in the drawings, if the faucet be opened to draw water, water from the main
enters the outer casing through pipe B', port e, pipe e³ and orifice e* and water from
the interior of said casing enters beneath the inlet valve through pipes 7 and a
to the interior of the cylinder A at its right hand end and moves the piston D towards

page_text: the left of Figs. 1 and 3, and the water in said cylinder at the left of said piston is
forced through pipes a' and at the left of Fig. 1 around the inlet valve stem /
through pipe over the top of the inner cylinder m' of the exhaust valve casing F,
through pipe k, and the discharge pipe C to and through the faucets not shown..
The piston D when it has nearly completed its stroke towards the left of Figs. 1
and 3, comes in contact with the lower end of the lever a see Fig. 5 and forces it
into the recess a thereby moving the lower end of the lever a' which acting upon the
army moves the valve rod b with the valve b towards the left of Fig. 1 and at the
same time disengages the lever f from the lug a at the left end of Fig. 1, thus
leaving the cylinder unlocked so that the weight of the piston will cause the left hand
end of said cylinder to be depressed and the right hand end to be elevated in which
position it is locked by the lever f at that end of the cylinder.
When the valve b and its rod 6 are moved toward the left, as just described the
port e is closed and the port el is opened, so that the water entering the outer casing
passes from the pipe B' through port el pipe e and orifice e³, and as the pad g' at the
right of Fig. 1 has been moved over the orifice the current or jet of water
escaping through said orifice impinges upon said pad and assists in tilting the
cylinder thus enabling me to use a lighter piston than otherwise would be practical.
It will be seen that, with the parts in the position shown in the drawings, the left
hand inlet valve and the right hand exhaust valve are closed while the other valves
are open said valves all being moved and held in their open or closed positions by the
action of the levers o' and of thereon as they are vibrated about their bearings at their
outer ends by the rising and falling of the two ends of the cylinder A. No register
has been shown, but it is obvious that a register may be applied thereto and worked
from the oscillating movement of the cylinder.
