IBM MASTER CLOCK MODEL 25-7 DATED CIRCA 1958 IN OAK

serial number E 20039

24v powered remontage system (big solenoid winds spring which maintains clock even through short power breaks).

Oak with glazed door
Size: 48" high x 15" wide.

I purchased this clock 3 years ago with every intention of using it as a 'project'* in my retirement, but I just haven't got round to it, and am unlikely to now.

The clock works perfectly, and is an incredibly good timekeeper.  I fixed it to the wall. plugged it in via a transformer (included), and away it went.  It hasn't stopped in three years!

These are the points which need attention, and were going to be the subject of my 'project'*:-

  1. *The seconds hand is missing.
  2. *Both locks have been forced (normal, I am told), and the door cannot therefore be locked. I have purchased replacement locks, but they have not been fitted.
  3. *The oak case could do with a little TLC.  No damage, just wants a good clean and polish.  Glass perfect.

The pendulum bob is chrome, the rod is invar, and both are blemish-free. No corrosion at all.

One additional feature of this clock is the addition of a bolt-on unit, called an 'accumulator', I believe. It can be seen attached to the lower end of the main movement.  I don't know it's purpose, or if it is complete, but is, I am told, quite a rare part.

Most detail can be seen from the photos, but any questions are most welcome. A lot of info is available on the internet.

Dear tickerwilli,

The add on part is an impulse accumulator. This unit stores the number of impulses lost in the event of a power failure and, on resumption of power, will output pulses at 2 second intervals until the correct time is displayed on the slave clocks. From memory, the spring will power the clock for up to 14 hours. The impulse accumulator is a differential. One side is driven by the clock movement, the other side driven from a solenoid as in the slave clocks. When electrical power is removed only one side of the differential is driven and the output of the differential moves. When power is restored and the once per two second inpulses are given, the output of the differential moves back until it is in it's starting position. The impulses then revert to one per minute.
Hope this is useful.
Phil.
