    Seth Thomas 9 1/2 International Time Recorder Co

    IBM did produce a short case master clock, a model A. This link shows what the movement looks like. However the wind holes should rule this clock out. My guess is it's a very nice face mounted on a wind-up clock movement. Dial may be off of an ITR secondary. A photo of the movement would tell...

    International Time Recording Co. Master Wall Clock

    Bruce, Yeah, I know this comment is two years old. Gleber's clock looks great but his weights are uneven. I certainly wouldn't use those Amazon hangers to mount this clock. I have a 1/4 inch diameter lag bolt into a stud for mine. Here are the installation instructions (pages 2,3, and 4) from...

    Japy Freres & Cie, got this in families estate

    Oh no! A bad penny (from the mint) is worth more than a good one. Did you ever get a photo or discription of the missing chains?

    So after three years the wife decided you could keep it? I like it!

    Nagoya Shoji - Info?

    I did a Google search on the image; it returned this: Image size: 349 × 152 No other sizes of this image found. Possible related search: language Search Results So you are probably right, looks like Google tagged it as a language, maybe Japanese. Someone could jump in that speaks Japanese...

    Nagoya Shoji - Info?

    Tthe scribbling is probaby the name of the person who worked on it at some time.

    Weight driven wall clock

    Here is a link where they talk about glazing putty in clocks. https://mb.nawcc.org/threads/original-putty.31418/

    Ridgeway Grandfather Clock

    My 1989 Ridgeway book says" The weights are marked on the bottom L (Left) , C (Center), R (Right). Hang each weight in order as you stand facing the clock." This is for cable driven movements. It is the same for chain driven movements. If you have the weights out of order they will not fall...

    Regulator

    Frank, I really don't want to scare you so don't let this intimidate you. There is an interesting video you may enjoy watching. Tim Orr posted this (post #3 in this thread) and It shows how to make a replacement geared wheel...

    Regulator

    How do you think those" highly experienced clockmakers" got their experience? Probably tinkering with a movement that was not worth fixing. Whats to lose? A movement not worth fixing but for the experience. By the way, the case looks nice and worth making it work again.

    Glad you got the weak secondary working. I'm going to look into using an ESP8266 NodeMCU pair to link up with each other to transmit an A pulse @ 60 per hour and an A pulse @80 pulses per hour along with a B pulse @ 40 pulses per hour. That should satisfy both the two wire and three wire...

    Those secondaries look Great! The Service Instructions say the movement should work with 3/4 rated voltage so two 9 volt batteries may be .75 volts too low. That's 6 volts below the rated voltage. If you have an Ohm meter I would like to know what the resistance of the coils are. From that...

    Here is a schematic for driving an ITR or IBM Two Wire Secondary via wireless IoT device (or Arduino or Raspberry Pi Zero W). It can be loaded with software to receive a pulse from your Master Clock's wireless transmitter or load a revised version of my the master clock software and get the time...

    The hands look like the ones on my 1955 model type 565-2. Maybe someone liked the older style hands and swapped them. I know these are original hands because I took it off the wall from Cove Elementary School where it was installed.

    Looks like my article (PDF format) may be a close match, with a couple of changes. I think Phil has already programmed a one pulse per minute part into his code but I don't have a plain impulse secondary so never needed it. I can check with him if you are interested. I would go with the...

    Wish Granted - United after ~100 Years.

    The secondaries look to be plain minute impulse (2 wire) secondaries. The IBM label (with serial number) indicates they are 24 volt DC coils. To operate the armature you need to apply a 24 volt DC voltage to the two wires for about a second for each minute's advance. There is no correction for a...
