Electrical Experimenter (04:12) April 1917

Hugo Gernsback, editor

"The clock consists of two steam or compressed air cylinders, built in one frame. A piston is placed in each of the cylinders which operate alternately with respect to each other. A large number of such clocks were installed in the laboratory of Dr. Nikola Tesla a number of years ago which are driven by a single generating unit. It is said that the accuracy of time attained by this ingenious clock system is far better than with any other system known."
This is the April 1917  issue of Electrical Experimenter. The cover story is “Wireless ‘Phone Talks with Aeroplane.” Also included are several radio stories, a clock design patented by Nikola Tesla driven by steam, and a short story by Thomas Benson.
