Description

This incredible, one of a kind revolution counter was custom built by the Navy Yard, New York Department of S.E. (Brooklyn Navy Yard) in 1906 for the famous USS Connecticut – Class Battleship, built between 1903-1908 (see battleship description below). The Connecticut was the only ship launched by the Navy Yard in 1906.

Details: This historic, then state-of-the-art, custom built revolution counter includes (3) front mounted gauges each with 7” diameter heavy brass threaded bezel, each gauge with 6” diameter glass panel.

From right to left, the first with open center, silvered face reading 0-9 revealing damascened internal gears and other mechanism, direct shaft driven pinion and gear mechanism with connection to twin hands, one manually set and other reading in actual revolutions in tenths. The second center mounted gauge with silvered face reading Revolution Counter Navy Yard, New York department of SE 1906. (Note: this was known as the Brooklyn Navy Yard.). With twin hands, one manually set and other reading hundredths off common internal shaft, marked 0-90. The third far left gauge with silvered face reading 0-90 in 1000ths with second chapter reading 0-9 in 10,000th by second, shorter hand.

Note: We have carefully dismantled the device and lightly lubricated moving parts. We have not witnessed any appreciable sign of wear and all appears to be in fine working order.

Other fine details include: an electrically operated solenoid that activates a spring loaded cross-shaft with linkage including drop-pins that when activated disengage breaking mechanism on spring loaded gauge drums allowing for remote reset. It is presumed that this revolution counter was bridge mounted or within the engine room.

Further details include an all brass top right hand side electrical brass electrical connection box stamped 125V with 1 1/4” dia knurled threaded access cover to electrical contacts. Note: it is presumed that access port used by electrical adaptor from remote location or direct connection to reset counters.

Final details include: common 3/8” dia shaft protruding from right left side of case. Note: it appears that the right shaft was used as evidenced by provision for set screw, each case shaft bearing plate with wick type oil cup. Complete with (4) heavy integral mounting brackets each with 5/8” dia hole.

This one of a kind analog device is in overall excellent condition, not polished or cleaned in any way, exquisitely cast, machined and orchestrated which would complement any museum, private, corporate nautical and/or Navy historical collection.
