    Default Le Brun, Pocket Watch movement.

    Hi, has anyone got an idea of what type of escapement this movement has? It has a similar Compensation Curb to a J R Arnold movement Serial Number 3639 on the David Penney site. I did not pay much for it. It runs. I think that Le Brun was a Huguenot from Belgium or France. Photos compliments of midwestestate. Regards Ray

    Something about the way the train-wheel pivots are crowded together under the balance makes me think this may turn out to be a duplex; so does the wide-rimmed brass balance, although this is also found on cylinders. Admittedly there are things in the back-plate which looks a little like the ends of banking-pins, but their position does not seem to relate to any of the visible pivots. I like the early form of maintaining-power on the fusee, with a blued-steel click. Altogether an interesting movement, whatever its specification turns out to be.

    Hi Oliver, I am inclined to agree with you that the movement is a Cylinder or a Duplex. My Parkinson and Frodsham Cylinder movement has a similar Jewel layout to the Le Brun and also has a 4 Spoke Balance Wheel. If a photo of the side of the movement where the escapement was shown, I probably would not have got it cheap. What parts do you think are missing in the 2 outlined in Blue? What do you think the the parts outlined in Red do? I can't find much about this maker? Regards Ray

    Hi Ray,

    The ones in the red line look like the ends of three steady pins and a screw; if it is a lever they could be part of a banking block, if not, then I'm stumped. In the blue line there was obviously a screw head in the largest of the lower group of three with two steady pin holes, and three steady pin holes and a screw hole in the upper group, possibly something to do with the balance brake?

    I'm guessing that it's an English cylinder.

    We'll just have to be patient until it lands in your mail box.

    Regards,

    Graham

    Well it is getting closer, I am itching to see what sort of escapement it has? "Your item departed a transfer airport in DUBAI, UNITED ARAB EMIRATES on February 19, 2017 at 9:05 am. The item is currently in transit to the destination." Regards Ray

    Well I am like a little Kid at Xmas waiting to open the presents. The Le Brun movement has finally arrived at the Post Office. I can't go there until the Groceries are delivered. The choice is go to the Post Office or not eat. This movement has been getting to me and I have been dreaming about it. See what happens when you start to collect early Pocket Watches and movements; you become obsessed. Collecting is definitely a type of addiction. Be careful John in Sweden! Regards Ray

    Hi Ray,

    Any clue as to what those extra holes were for? Nothing's apparent in the pictures.

    Hi Graham,

    I will have a look. What about the Hole in the Balance Cock? It is very early for a Table Roller? I forgot to mention, we have a Cyclone going past (I Hope) in the next few days; sometimes the Power goes off so I got a new lantern Battery yesterday. Regards RayClick image for larger version.

    Hi Graham, I think that you are right.
    possibly something to do with the balance brake?

    Hi Ray,

    Regarding dates, the engraving on the top plate looks as though it's been done by machine or a pantograph, (same thing?), but I don't know when these came into general use. It implies a machine-made movement, which I think began to be produced around the 1850s, but I may be wildly out with this. On the other hand, that does seem rather late for a compensation curb. Are there any marks under the dial?

    I think that hole in the cock table is for a missing steady pin, because there's one still there diametrically opposite it.

    Regards,

    Graham

    Hi Graham, I had to take the Dial off anyway because when the Gold Case was ripped off the Hinge went with it. Nothing on the Pillar Plate; the Dial missing one Dial Foot has "Pat" on it maybe some clue. I have taken a photo of the Engraving so that you can have a better look.

    It is Flush with the bottom of the Balance Cock. I think that the movement is a lot earlier than the 1850's. Click image for larger version.

    Hi Ray,

    You could easily be right about the date, I'm really not sure. I suspect that the dial has been replaced, judging by the two empty holes in the brass edge.

    The engraving of the signature and the serial number both look too regular for hand work, but the "London" probably is by hand.

    Regards,

    Graham

    Hi, I finally found a reference to this Maker: Pendule de l'horloge astronomique à gaine, fabriquée vers 1850 par Joseph Pascal Lebrun (1807 - 1883) à Luxembourg. Photos and information From Wikimedia Commons, the free media repository. It may be him and later he moved to England? Click image for larger version.
