In application No. 4029 of 1887 I have described certain improvements in the con-
struction of liquid meters part of such improvements relating to the construction of
valves used therein.
My present invention relates to further improvements in valves of the nature
therein described.
One of the objections to the valve as formerly constructed was that the flow or
current from above the diaphragm to the outlet valve-chamber was obstructed by the
spring carriage which was placed directly in part of the opening to the valve. I
now propose to remedy this by placing the spring carriage above the valve chamber
and to connect the valve-spindle with one end of a bell crank lever upon the other
end of which are flexibly connected pins carrying spiral or other springs. The
outer end of said pins rest in a pivoted frame which is raised or depressed by the
notion of the diaphragm of the meter, the play of said frame being limited by suitable
stops.
Another of the objections to the valve as formerly constructed was that the flow or
current from the inlet valve-chamber to the intermediate valve-chamber was
obstructed by the tube through which the piston rod passed and by the projecting
shield. This I now propose to remedy by removing the tube and shield and sub-
stituting for them two tubes through which a divided piston rod passes, said tubes
being so placed that they are out of the direct line of the current from the inlet valve,
but still obstruct equally the flow from and to the intermediate water ways in the case
of the meter. The divided piston rods pass through such tubes, said rods being
attached top and bottom to cross frames, that at the bottom being in turn attached to
the diaphragm rod and that at the top serving to actuate the indicating mechanism
and also by means of suitable connections to move the pivoted frame the springs upon
which serve to throw the valve in substantially the same manner as described in the
previous applications.

page_text: I, CHARLES CASIMIR BARTON of the Windsor Hotel, Edinburgh, North Britain,
Engineer, 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:
In specifications Nos. 1561 dated 27th March 1883 and 2876 dated 4th March 1885
are described certain inventions regarding water meters and in specification No. 4029
dated 17th March 1887 I have described certain improvements in the construction
of liquid meters part of such improvements relating to the construction of valves used
therein.
My present invention relates to further improvements in valves of the nature
therein described, and in order that my invention may be clearly understood reference
is made to the accompanying drawings which form part of this specification and in
which-
Fig. 1 represents a sectional elevation of my improved valve.
Fig. 2 is a plan view complete, and
Fig. 3 is an end elevation.
One of the objections to the valve as formerly constructed was that the flow or
current from above the diaphragm to the outlet valve chamber was obstructed by the
spring carriage which was placed directly in front of the opening to the valve. I
now propose to remedy this by placing the spring carriage a above the valve
chamber A and to connect the valve spindle & with one end of a bell crank lever c
pivoted at c, upon the other end of which are flexibly connected pins c² carrying
spiral or other springs c³. The outer end of said pins rest in the frame or carriage a
which is also pivoted at c'.
Another of the objections to the valve as formerly constructed was that the flow or
current from the inlet valve chamber to the intermediate valve-chamber was obstructed
by the tube through which the piston rod passed and by the projecting shield. This
I now propose to remedy by removing the tube and shield and substituting for them two
tubes d d through which a divided piston rod d' d' passes, said tubes being so placed
that they are out of the direct line of the current from the inlet valve, but still
obstruct equally the flow from and to the intermediate water ways in the case of the
meter. The divided piston rods pass through such tubes, said rods being attached
top and bottom to cross frames d² d³, that at the bottom being in turn attached to
the diaphragm rod D and that at the top serving to actuate the indicating mechanism,
and also by means of connecting rod ee and cross frame e¹ to move the pivoted frame a
and through it the springs c which in turn act upon lever c, and serve to throw
the valve in substantially the same manner as described in the previous applications.
The entire operation of the valve being as follows:-it being understood that
when the diaphragm is at the top of its stroke the parts are in the position shown
in the drawings.

page_text: As the diaphragm descends the rod 1) travels with it and the cross frame el comes
in contact with the top of the valve casing A and stops, while cross frame d travels
down rods e (which it loosely surrounds) until it comes in contact with the projecting
piece a¹ of frame a which it carries down with it, compressing springs until
frame a passes the centre line of lever c when the springs instantly act and throw the
top end of lever c up and thus throws the valve just as the diaphragm has finished
its proper downward travel. As the diaphragm moves up, cross frame d² travels up
rods ee until it meets the top nuts thereon when it begins to lift said rods and
connected cross frame e¹ (which loosely surrounds rods dd) until the springs c³ on
carriage or frame a have been raised past the centre line of the top arm of lever c,
which is then instantly depressed throwing the valve just as the diaphragm reaches
its proper limit of upward travel, suitable stops being arranged to limit the play
of the bell crank lever.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is -
The improved arrangement and construction of liquid meter valves substantially
as described and as illustrated in the accompanying drawings.
