***** RARE ! U.S.Navy Telechron Ships Clock *****

If you are a US Navyor Marine Clock Collector this is a \"must have\"

Up forsale is a rare 1930\'s Telechron clock using Henry Warren\'s patented 115/120 volt, 60 cycle AC motor. For many years, millions of household and commercial Telechronclocks were manufactured and clearly this is the largest ( by quantity ) master clock / slave clock system in theworld and it is based on his 60 cycle AC motor.Consider the Telechron motor as a \"slave clock movement\" it keeps perfect time as long as the ship\'s powergenerator is putting out exact 60 cycle current. ( Note: The August 1991 NAWCC Bulletin has a 14 pagearticle detailing Henry Warren, his life, the Telechron slave clocks and thepower generating station master clocks. )This clock is the subject of s soon to be published article.

The patentshows how interesting and complicated these clocks really are ( google the fullpatent). On December 31, 1935, a patent (#2,026,368) was granted toHenry Warren, for \"ELECTRIC CLOCK AND SYSTEM\" described in the first paragraph of thepatent as .......\"particularlysuitable for use on ocean going ships such as naval vessels although notlimited to such use\"....... Thegenius of this clock design is it can be remotely reset (simultaneous with all other clocks on the ship) and hasadditional functionality. The typical hourly reset or noon time signalsynchronizer reset on stationary \"land based\" clocks is fixed tohourly only but cannot be remotely advanced or retarded to any chosen hour andthen to the exact hour and 60th second AND then synchronize new times on allthe slave clocks! A special Telechron design set of control switchescan set a new time on all clocks and have time held at any full hour waitingfor the \"start\" by a radio time signal or a chronometer etc. and thatway insure all clocks are coordinated at the same time at any location on theship ( to the second ). Remember as youhead East or West ships time changes hour by hour.

Using the Telechron schematic, I made a \"homemade\" boxwith 3 toggle switches for the master control, mounted to the left side of the clock.The top left toggle turns all motors onand off, the top right toggle willenergize the magnet latch that places a hard stop on the hour/minute hand andseconds hand. The bottom toggle is rapid hour advance/retard. As the ship moves east or west the clockswill have to be adjusted, a procedureoutlined in the patent, would have youuse the rapid advance or reverse motor (it moves the minute and hour hand ineither direction, rapidly, at about 18seconds per one full hour ). The wiring diagram shows a magnetic latch. A separate block ( locked from the magneticlatch ) on the back of the movement willlock and hold the minute hand at the top of the hour. Holding the minute hand also stops the hourhand at whatever full hour it is on. Youmust do this procedure perhaps 2 minutes ahead of the new synchronizing time toinsure that the seconds hand on all clocks has at least a full minute to make afull rotation and now is at the \"holdingposition\". You monitor a slave clock next to these control switcheswhich is in line with all the other clocks. At the start signal you would open thesynchronizing hold magnet latch relay switch and on all the clocks the threehands will start moving and keep a new time. Note at the 2 o\'clock position there is awater tight cap that unscrews and the original key that hangs on a chain to setthe time manually to any hour and minute. U. S. Navy contract name plate showsthe clock manufacture date of 11-1935 as compared to the patent date ofDecember 31, 1935.

There heavyBakelite clock case has almost water tight seals and easy to read bright goldnumbers on a 9 inch dial and gold hands against a black background. The clock,dial and movement has a protective inner case with electrical contact points onthe back to marry the fixed contact points in the Bakelite wall mounted case.There is a standard 60 rpm motor and a very special long shaft motor with 2transformer coils one for either direction for rapid advance of time or to gobackward with time! Some items havearrows in the photos pointing to them.This clock and the telechron motors have been professionally servicedand the entire clock has been fully cleaned oiled and adjusted. This is one ofthe best examples of these rare clocksthat you will ever see on .

I can workwith the buyer on other shipping options and costs and the actual clock with controlpanel is 18\" by 14\" by 8\".Please email me with any questions and thank you for looking. The clock weighs around 20 pounds and will require a large box for shipping.
