Restoration of a TIFFANY "NEVERWIND" CLOCK  C 1899-1910

                                                 

I have currently two of these clocks in for repair and before starting on them I need to find some spares.
If you have or know of somebody that could help please PHONE me at 

01359 269601

I now have the spares to complete the repairs on these clocks and my thanks go to:-
 Mick Wilson
of The Clock Centre London  
 for supplying the necessary parts. My thanks also to John Smitt of Texas and  Don Reeves of New York for their help and advise in restoring these clocks
More pictures and notes will be added to this page as the repairs progress 
These clocks  were first patented by George Steel Tiffany of New Jersey U.S.A. in 1901.This clock however was probably produced after 1911 as  it has only one impulse arm, the earlier models had two,( if you would like to see one CLICK HERE)

This picture shows some of the clock parts I have so far cleaned and repaired ready for assembly They include the two coils which were rewound on the lathe. Each coil has 10 tightly  wound layers of 32g enamelled copper wire and the resistance when wired in series should be about 50 ohms. Unlike some early battery clocks this clock was designed to run on 4.5 volts, and it can be a problem fitting three "C" cell batteries in the bottom of the case.

This picture shows the thin spun brass base and pressed brass frame with supports.

 

This picture shows the two inverted cups which forms the pendulum  ( it's quite heavy and care must be taken when fitting it to the thin suspension wire) If the original wire is missing use Horolovar size.0045 this is long enough for the job but may need to be thinned a little for correct timekeeping Picture of the back plate showing the arm for the suspension wire, unfortunately what it doesn't show clearly is the two eccentric rod and nuts used to adjust the action of the ratchet and armature, but more about this latter.

                

 

This was the condition of the dial as received both chipped and cracked, The newly wound coils ready to fit to the movement- they should have a resistance of 50 ohms when measured in series and be tightly wound on their bobbins. 
This is a rather crudely wound coil but never- the- less it's very important because as the circuit is broken the magnetic field collapses and in so doing produces a high voltage which would quickly damage the contact points --.the coil prevents this. I have seen diodes used on the Eureka clocks to do the same job
 Coil shown as taken from the clock

This picture shows the all important bit!! and is quite complex:  it is a brass tube riding freely in the bushing and must never be oiled. Inside the shaft tube is a brass rod electrically insulated from the tube by a cotton raping  and two fibre washers, (one at each end) and terminates in a collar carrying a hairspring, which in turn is connected to the top end of the coil shown opposite. 

                  

The tube at the top with the cotton insulated rod
shown below-this part seems to give the most problems!
