PROVISIONAL SPECIFICATION.
Improvements in Meters for Measuring Gas or other Fluids.
FRANK WRIGHT, Gas Engineer of 36 Millbank Street, Westminster, in the
County of Middlesex do hereby declare the nature of this invention to be as
follows:-
My invention has for its object certain improvements in the construction of meters
for measuring gas and other fluids and is chiefly applicable to meters used for
experimental or testing purposes, such meters are technically called Test Meters.
It consists in fitting to the index or recording mechanism of said meters a bell or
gong arranged to strike at any predetermined period of revolution of the index or
counter and thereby give a warning by sound that a certain volume of gas or fluid
has passed through the meter.
For this purpose I provide and fit on the shaft or spindle driving the index or
counter or any of the other spindles or pinions in the index, an excentric, cam,
pin, or other suitable device in proper relation to the tail end of a lever provided
with a hammer head, the said lever having a fulcrum or pivot attached to some
rigid portion of the frame of index or case of meter.
I also fix a bell or gong in
suitable relation to the hammer which I also mount upon a rigid support attached
to the frame of index or casing of meter. The device is similar to the striking
movement of an ordinary clock denoting volume instead of time.
The action of the apparatus is as follows: The index or counter of meter being
set to zero or other convenient position, gas or fluid is allowed to pass through the
meter and in consequence imparts motion to the index and eventually causes the
excentric, cam or pin to lift the hammer and strike the bell or gong.

COMPLETE SPECIFICATION.
Improvements in Meters for Measuring Gas or other Fluids.
I FRANK WRIGHT of 36 Millbank Street Westminster in the County of Middlesex
Gas 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 :-
My invention has for its object certain improvements in the construction of
meters for measuring gas and other fluids and is chiefly applicable to meters used
for experimental or testing purposes (technically called Test Meters) and consists
in fitting to the index or recording mechanism of such meters a bell or gong so
arranged as to be sounded at any predetermined period of revolution of the index
or counter and thereby give an audible signal that a certain volume of gas or other
fluid has passed through the meter.
Now according to my invention I attach to the shaft or spindle driving the
index or counter or any suitable spindle or pinion in the recording mechanism
an excentric pin cam or other suitable device which acts on the tail end of a
hammer lever pivoted to any suitable portion of the frame of the index or meter
case. This hammer strikes on a gong or bell attached to any suitable portion of
the index frame or meter case.
And in order that my said invention may be the better understood I will proceed
to explain the same with reference to the accompanying sheet of drawings in
which a represents the index frame the bell or gong e the hammer d the hammer

page_text: lever the pivot g the cam to operate the hammer the bracket to which is attached
the bell or gong bi is one of the wheels of the recording apparatus ; the spindle of
the same to which the cam g is attached.
The action of the apparatus is as follows The index or counter being set to
zero or other convenient position gas or other fluid is allowed to pass through the
meter and imparts motion to the wheel i and spindle; thereby causing the cam g
which is attached to the said spindle to rotate and raise the hammer h into the
position shewn by the dotted lines and allow the same to fall by gravity and strike
the bell 6 when the said cam is in the position shewn.
If the bammer cannot be so fixed as to fall by gravity the same may be caused
to strike the bell by means of a spring.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
In meters for measuring gas or other fluids the combination of a bell or gong
and a hammer actuated by the recording mechanism substantially as and for the
purpose stated.
Dated this 23rd day of July 1892.
