Question
I have a grandfathers clock that I acquired that doesn't run. It has a Hermle 451-053 movement. I saw this answer that you gave and was wondering where the escapement crutch was. The clock looks to be in good shape but when I start the pendulum to one side and leave it go it only runs for a minute or two. Or do you have any other ideas?   Larry


THE FIRST LEVEL IS THE SETUP.  

If a clock movement is in operating condition but not working, I would check the stability of the clock in that it doesn't rock or wobble on the floor.  It should be relatively level.  The level is not critical, as setting the beat (below) will correct for this.  

Next, verify that the weights are hung correctly.  On most clocks the weights vary in weight.  The general rule is that if two weights are equal, the third weight, if it is heavier, goes on the right side (as you face the clock).  If the third weight is lighter, it goes on the left.
Is the pendulum hanging configuration correct?  This means that the suspension spring, hanger, verge and pendulum are all connected properly with nothing broken, especially the suspension spring.  When the pendulum swings, it should be "in beat", meaning that when the pendulum swings you hear an even tick....tock....tick....tock.  If it is uneven, like tick..tock......tick..tock, the clock will probably stop.  Most later model movements have an "auto-beat" mechanism.  The beat can be set by holding the pendulum over to one side next to the case and releasing it.  It will automatically correct itself.  If it does not have this feature, the escapement crutch will have to be slipped manually.  If required, I can give you instructions for that.  I will need the model of the movement.  This can usually be determined by all the information found on the back plate of the movement.  Also check to see if the hands are catching on each other or the dial.  Look at the chime and strike hammers to see if they are all in alignment at the rest position.  Sometimes jammed hammers or the drive mechanisms will stall the clock.

Answer
Larry, the crutch is the arm (part if the verge assembly that comes out of the top back of the clock and connects to the hanger. The hanger is the arm that is approximately 6" long and hangs from the suspension spring.  The pendulum hangs from the hanger. You did not state whether you checked the beat to see if it was even.  If it is not, the crutch should be slipped to obtain the even beat.  Have you check all of the other items listed?  Let me know what you find.

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.
