Slattery Induction Meter (1889-1892) Up
Not much is known right now about this meter, but it was a lamp-hour meter to go with the electric system developed by Marmaduke Marcelus Michael Slattery (whew!) for the Fort Wayne Electric Company.
This meter was designed and sold prior to Thomas Duncan's arrival at Fort Wayne, and was discontinued after Slattery passed away in 1892 (all the equipment he had developed was quickly discontinued in favor of better equipment developed by J. J. Wood and others at Fort Wayne).
