Missing Spring?

Recommended Posts

So, a friend has bought a nice looking 1930s German wall clock. The standard R&A Vienna style. He asked me to get it going but when I went to fit the pendulum there was no suspension spring. I only managed a few pics but am I missing something? I can't see how this clock would work without a pendulum but no idea how it would fit. Hopefully he'll bring it round so I can have proper look but any thoughts would be much appreciated.

Hi  The fact that it has a crutch confirms the point that it should have a pendulum and suspension but looking at the escapement pictures where it fits is an other thing. need a few more pics of the escapement block and fittings, and one of the clock front.  A check on th front for a makers mark.

You are missing the block that screws onto the balance cock. Does the dial have a little hole above the 12 on the dial because if it has then it will be a Brocot suspension block. See photos, if not it will still be like the photo but not with the long adjuster.

I've never seen screws like the ones holding the movement together before.  Any chance the pendulum is carried in another section of the clock and the movement just racks in aligning on those screws.  It also has a very generously relieved crutch.  Possibly for better alignment of two parts that you may not have a hand on at the time of installation.  That would also reduce the possibility of damaging it or unintentionally affecting its rate.

Just spit ballin.

I just picked up a clock with an identical movement at an antique store in France.  I puzzled over the same issue. I think that Shane above is correct. My clock is missing the suspension spring, but the movement works perfectly.  The movement slips into the wooden case and is held by a brass bracket. At the top of the bracket is a protrusion that has both a slit  and a small hole for a pin.  The pendulum would seem to fit perfectly with a small suspension spring (which I don’t have yet) that fits into the slit in that protrusion. When the movement is attached to the bracket, the crutch should align with the pendulum.

    • There is a tool to straighten this, but it will cost you 50x this wheel.
    • The devil's creation. They peeled off very easily, yeah no not recommended. 
    • You have a very low chance of straightening this, it should be made of hardened steel, which is very brittle. Maybe you could ask for a refund from the place where you bought it? If you go ahead and try to straighten it and it breaks then nobody will refund you.
    • I had purchased this wheel online but the upper pivot is a little bit bent how can a straight it?
    • I've hit this snag a few times and my solution is to hand wind, don't be tempted to crimp in the spring so that it catches the smaller arbor - nothing but misery lies down that road. A new spring is a reasonable solution if you don't mind the wait - given my location this can be more than 2 weeks and postage is often several times the cost of the part so not very practical. Perhaps another brand of winder may not have this issue, but after the pain of buying the Bergeon generic partial set I couldn't face the cost of a second different set. I did purchase a Chinese set when I was starting out, and lucky enough to get a set with steel arbors (most are brass), but they are caliber specific so unless you happen to be working of that specific caliber they are pretty much useless 99% of the time.
