    Looking for some advice about the restoration of the bracket clock in the photos. It's a bit of an oddity which probably dates to around 1740? It's single fusee and as has the holes for silent pull repeat that I think are modelled on Knibb's silent pull qtr repeating mechanism. There is a snail wheel on the central arbour and also two small holes in the small wheel above the snail for the qtr repeating. It appears there are two holes for hammer arbours and springs so I'm guessing it originally had two hammers. But I can only see holes for one bell does this make sense? I assume there was a spring on the pull repeat wheel to power the striking?Does anyone have a photo of a similar movement. I'm looking in Hobson's choice to get a better idea as well and have several photos of similar movements. I've marked so of the missing parts on one of the photos some of which are the scribe lines.

    It also has anchor escapement and originally I assumed it had been converted from anchor. However there doesn't appear to be any vacate holes for a verge and because the movement is smaller the wheels are positioned diagonally rather than mostly vertical so the centre wheel would get in the way of a contrate wheel. The collets on all the wheels are very fancy and identical which also makes me think it's actually original. However, the deciding factor was that the escapement wheel is actually scribbed on the front plate with all the other wheels confirming its originality. The pendulum also seems like an original bob and not like a normal anchor pendulum. The anchor spans 4 teeth so not the usual definition of tic-tac at 2 or 3 teeth. I've never seen a clock like this before and I guess its possible the tic-tac has been changed to anchor but the clock was never verge.

    Here's an example of Knibb's work which shows what I think is missing:

    Dean, do you have the book, Hobson's Choice? It is a study of English repeat mechanisms.

    Regards, Ralph

    Nice clock!! Would be a nice project reconstructing it back. I know someone who would love to do it if it was his clock :)

    I had not noticed before that this dial has the cartwheel cutouts usually ascribed to a Northern clock. (It comes down at least as far as the Cotswolds but it is far more common in the North.)

    I've never seen that on a bracket before, but I have seen far fewer brackets than you, have you seen it before? The Bullock we looked at from Ellesmere did not have it.

    Hi Guys,

    Thanks for your replies.

    Ralph, its is very similar to the clock on pages 36 and 37 of Hobson's choice. I'm just not quite getting how it works but i'm close to understanding. The pin wheel on the winding arbour for the pull repeat has 12 pins on one side and 3 on the other for the hours and quarters respectively.

    Here's a John Knibb example with wonderful photos.
    31837 John Knibb, Oxon - Campbell & Archard (Derek Roberts Antiques)

    Nick, I've never seen cutouts before but I've never really looked either!
    I'm a bit confused by the date of the clock. The ringed pillars are early but the dial looks later in style. I guess that is probably a function of it maybe being a country clock?

    Anyone seen an original anchor of this age with bob pendulum? The pendulum crutch is really nice as you can see on the photo.

    There is a signature on the back of the dial but I can't make out what it says or get a good photo as yet.

    Thanks
    Dean

    Found a signature on the back of the dial. Cant tell what it says - Warburton maybe?

    Could be clockmaker, location or later repairer.....

    Another detail in your pic is interesting too. These gaps are called cutouts, but though we all do that it is a misleading term suggesting that they were removed from the dial plate after casting. Although I'm sure some may have been robbed out like that the majority are as yours with the gaps part of the original casting. You can usually see a bit of flash. It shows that they cast them pretty close to their final thickness which is very clever, the are all hammered afterwards but I think you can see from the flash that there has not been much change in thickness.
