Vienna regulator suspension

[steve wilson]

I have acquired this clock, cleaned and oiled the movement, but the suspension is missing. As I am unfamiliar with this style of clock, I'm not certain what it should look like or how the pendulum will attach to the leader (if there even is a leader involved). I looked through Merritt's and Timesavers catalog and I can't quite come up with a solution. I have (hopefully) attached some pictures.

Any advice??

Steve, the tapered piece on the top of your pendulum looks like a Gustav Becker fitting. Is it tapered top to bottom and also on the sides? If so it requires a special pendulum leader with a matching "pocket" for the tapered block to fit into.

Your pendulum leader will look like this. This one may even be correct and fit. Alas, someone whacked off the top so it'd need extended with a bend and slot at the top to hang on the suspension spring. You're welcome to it. It's FREE!

Is the suspension by chance in the case? Often the suspension spring and leader are attached to the back of the case above the movement, and the slot slips in around the pendulum leader.

The suspension does not use a leader. It's simply a 2 flat spring block with a pin, available in many sizes from parts dealers.

I can post a photo of a nearly identical movement with bracket and pendulum that I'm currently repairing if you like.

Alright, here are two pictures. The only problem I noted is that your pendulum seems to be too short at the top (steel rod) for this type of setup. It's possible that the pendulum does not go with the clock. If it did have a Becker type hook like the one shown by Scottie, then you would not have that type of bracket with the suspension spring block at the top of it. Instead, the leader would be attached to the back of the clock.

Also: your pendulum is assembled incorrectly. The screw on the centre piece is meant to be hidden on the back side of the pendulum. It should also be much higher (centered). See the photo I posted above for reference.

[Scottie-TX]

Certainly that would work SOO, if he replaced or extended the center rod with a longer one and installed that type of hanger, but his has a trapezoid shaped hanger that was meant to be hung from a leader.
The centerpiece SOO describes is that dressing bar about a third up from the bob on the grid and, "Yes"; Screw should be to the rear - hidden.

Sooth's pic's show pretty clearly what you need. Let us know if you need more help understanding what you're seeing :)

[Sooth]

Scottie, I understand that he has the trapezoid top, which is why I think it's the wrong pendulum. The bracket goes with the movement, and the back crutch matches the type needed for the setup I showed, so that just leaves the pendulum. They are fairly easy to find on eBay.

Actually, if you're handy, you could easily modify this pendulum to work. You'd need a die to match the bottom thread, a new length of rod, and a "French style" top hook from Timesavers.

[Scottie-TX]

O.K. Understand your thinking, SOO. All us bin assuming pendulum is correct and original. You suspect it may not be and well, it may not be original. You are probably correct in your thinking - especially if it's not a GB movement. I don't know that the trap mount was exclusive to GB, however, it may be.

[Sooth]

I, myself, have not yet seen another maker with a similar trapezoid hookup. I've only ever seen it on GB clocks. I highly doubt this movement is a GB, as they are *usually* clearly marked. Most other makers used loop and hook style attachments.

Hey Sooth, Thanks so much for the pictures. I completely understand the situation and I agree it's the wrong pendulum. I am going to attempt to modify the pendulum I have, although I have found that the thread, pitch and size appear to be a I shouldn't have said that!I shouldn't have said that!I shouldn't have said that!I shouldn't have said that!I shouldn't have said that!I shouldn't have said that!I shouldn't have said that! and the closest rod diameter I can find is .092 and mine measures at .098 (or 2.5 mm). I think I can make something work, thanks again for the pictures and help.

Thanks for your input, I'm going to try to modify what I have!
