Question
Dear John,
The strike and chime train chain wheels will only allow the weights to be pulled up and will not rotate the other way (as if there is some ratchet or clutch device stopping them). So no strike or chimes.
The time train works perfectly.
As I built the clock myself from a kit(Emperor 120)I can confidently remove the movement from the hood, but as specialist knowledge is required for the movement itself, I would appreciate your input as to whether you think an enthusiastic amateur could overcome this problem with guidance from you good self.
As horologists are thin on the ground where I live, the main reason, together with lack of service information from the manufacturers, is I suspect, the reason for this malfunction.
Any information on oiling and greasing points would be appreciated.
I think it is fantastic that you and all the other horologists are prepared to give advice to us (reading the Q's & A's was very enlightening) and if you could possibly answer my problem I would be very appreciative, knowing how busy you must be.

Many Regards,
Brian Andrews. Warwickshire, UK

Answer
Brian, you are correct in that the ratchet wheels allow the chains to be pulled up in one direction.  That is the purpose of a ratchet.  You hear it click as you wind the clock as it goes past each ratchet tooth on the wheel.  Then the only way the chain can come down is when the clock is functioning and the wheels slowly turn in the opposite direction, allowing the gear train to move.  It could be that the clock needs servicing.  I recommend servicing every 7 to 10 years.  First, check the chime hammers and see if any are out out of alignment with the others.  It could be that one of them is jammed.  If so, gently pull back on all the hammers and then release them.  If that doesn't work, you might need to service it.  Can you give me the information on the back of the clock movement so I can identify the type?  It would probably be the Emperor 100M which is the Jauch 77, or the Emperor 101M, which is the Hermle 451-050 94cm.  My email address is below. Please reply to that and I will be able to send the information and it will free up my Allexperts question queue, as I have a limited number of questions allowed per day.  When I get to my shop Monday, I will send you some instructions and labeled photos on lubricating the movement.

Note concerning questions not related to Allexperts:  Because of my commitment to answering Allexperts questions within a prescribed time limit and the large backlog of clock work at my shop, I regret that I cannot answer personal email questions on a timely basis, other than Allexperts follow up questions.  I will try to answer these emails as soon as I can. Thank you for your patience.

Expertise

As much as I would like to offer values of clocks, I am not a certified appraiser and will not venture into giving an unresearched guess. There is very little published information on what I consider to be the value of "modern production clocks". Considerations are what the clock originally sold for, the condition of the case and movement, and particularly the area in which you live, the demand and the economy. ALSO, WATCHES ARE NOT MY FIELD. However, I can advise the clock owner on proper maintenance of a clock to keep it running, small corrections and adjustments and how to move a clock without damaging it. I can also advise on obtaining parts for clocks. It helps if you can send any information on the clock movement which is usually found on the back plate of the movement. I have been a clockmaker for about 35 years and was plant engineer in the mid 90's and later operations and engineering consultant at Emperor Clock Company in Fairhope, Alabama. I now have my own clock shop.

Experience

One of my greatest accomplishments was traveling to China to assist a clock factory in building clocks to the standards which we required. With the proper specifications and quality control, some beautiful clock cases were built. The factory people from the wood carvers to the plant manager were very congenial, friendly and I left a lot of wonderful friends when I returned from my trips.
