Water Pressure Gauge
The pressure gauge on the large water tank in the basement of the house I grew up in. Charles Smith Mersick was born in New York City in 1840. After education in New Haven and work in the hardware and metal business, he formed what would become C.S Mersick & Co. Interesting photos of the interior and exterior of the company can be found by clicking on the title to this post.
Bell installed his first telephone exchange in New Haven in 1878 and published the first phone book-a single page-including a listing for C.S Mersick & Co.

Mechanical Delay Device
Out of a high current-50 amp-relay rack likely used to control large motors. This device, actuated by the gray bar at lower left, introduced an adjustable delay of approximately one second after the solenoid is powered up. This is a pneumatic device with a knob, top rear, to change the rate at which air escapes. The motion controls a switch, top left. We have six of the large three-phase relays.
