Simmance-Abady Automatic Stop Meter, Figs. 4796-4799. 



The stop movement is a very simple one, being exact and shutting off a tap on the outlet of the meter. It 

 can be set to shut off from jV to 10 ft. of gas in tenths, while the stop movement can be also put out of action 

 altogether. A second pointer enables the hourly rate to be adjusted.
