    This my second early Hauck No. 2437. It still has it's original hands, original key, and possibly the original glass dome. It has had some work done, several pivots are bushed, the plate pillars are reversed, and everything is coated in lacquer (and oil). The only real defect I've found (so far) is the regulating screw was broken and repaired.

    This is one of only four I've recorded with the small silver dial. The other three are 1323, 1348, and 1796.

    This would be plate 1610 from c1904.

    I think this is lubed well enough. The entry pallet seems a bit on the short side. Shouldn't it stick up a little bit through the top of the anchor? It's been running like this for a few hours now. Feeble rotation but keeping time.

    Looks like they ran a special at the local garage: "Get your car lubed here and we'll do your clock for free." The pallet does look short on the top; how does the length compare to the other side on the escape wheel side?

    The exit pallet is about twice the length of the entry side. The lengths below the anchor are about equal. Locks and drops are close but one tooth hangs up on the exit side.

    It's been running ok like this for about six hours so far, and getting about 210 degrees of rotation per beat.

    I would suspect that the anchor pin doesn't stick straight up but rather off to one side. Does the pin travel more to one side than the other? I seems to be, given what little I know, that the pallets are part of the same large circle and that moving them equally, that is one up and the other down the same amount, would serve to change only the position of the anchor pin. Obviously, if the pin is too far to one side, it takes more and more power for the spring/fork to provide impulse to the pin. That's probably all jumbled up in theory! :p

    Hi Kurt,

    I looked at the movement of the anchor pin last night thinking the anchor was shifted towards the exit side, but no. It appears half the length of the entry pallet is missing for some reason. The screw in the anchor has just enough of the pallet material left under it to hold the pallet in place. I'll examine it more closely when I clean it, but for now it's still running.

    For this clock, each pallet is held under the wide head of a single screw. I think this was the design used for all the earliest Haucks. I also think it would be more difficult to adjust because moving the screw would shift the pallet. Most other adjustable pallets I've seen use two small screws and a strap.

    Eric -

    Could it be that one of the pallets is not original, and that something was substituted to get the clock running?

    Kurt,

    That's what I suspect, or someone decided to do some grinding.

    I think some one decided to sharpen the pallet...
    or grind as etmb61 said.

    and poing! the grinder/polisher tossed it into never never land.

    :-D that has never happened to me!

    they found some bit that would work.

    in any guess, consider it an opportunity.
    now you have a "Reason To Hunt!" through clock parts.

    ... like I ever need one, what am I saying?

    Nice clock BTW

    Usually, you can see if it has been moved by the patina. If moved, there will be some spot shinier than the rest where it was once hidden under the screw/part holding it. Another thing you might want to try is to set it out on a flat surface resting on the pallets. The anchor pin should be straight up. I used this method once and discovered that it was off, even though I could see no brighter area. I kept thinking that one side looked marginally longer than the other, but was not sure it just was not my imagination. It also gave me a reference as to how much to move the pallet that I suspected was too long and it did the trick.

    Seems we've lost the pictures so here they are again. It ran for about 19 days on 1/2 turn of the key so I think it's ok with the pallets. (I bumped the table it was on last night and then knocked it out of beat lifting the dome off so it stopped overnight. oops!)
