    I received a Wm L Gilbert clock yesterday for repair. It was gifted to the present owner from his grandmother's estate. The family said that the clock hadn't run for at least the last 40 years or so. It was clearly rebushed in the past, but there was almost no wear at all. The last date scratched into the case was 1973. After initially cleaning all the gunk from the pivots, I realized that it was way out of beat, as I had to raise one side of the case nearly 1/4" for it to run. Now it has been cleaned, oiled, and adjusted and had been running just fine for the last 48 hours.
    A couple of questions for you Gilbert experts out there. This is the coolest pendulum that I have ever seen. When you turn the rating nut, the dial moves on the pendulum. It looks like someone tried to adjust this one by turning the pointer, and broke the end off.
    What to the numbers on the pendulum dial represent? It reads from 0 to 100 around the dial.
    Judging by the label, I'm guessing this clock is from 1874 - 1875. It this a correct assessment?

    I would place the date of the clock several years later. Tran Duy Ly's book on Gilbert clocks shows the Lebanon from the 1885 catalogue, though it may have also been offered a few years before and after. The pendulum was patented in October 1883, so, if original to the clock, that suggests the clock was made no earlier than late 1883. Your clock, BTW, seems to be missing the drop finials on either side of the dial, unless they were purposely removed for some reason.

    Many clock companies used a similar style of pendulum, and I have always wondered what the numbers represent specifically. The patent on the Gilbert pendulum mentions them but offers no explanation.

    I believe the numbers only give you a reference. Say the indicator points at 25 and the clock runs slow. You move the bob so that the indicator shows 50. Now the clock runs fast. You know now that the correct setting will be somewhere between 25 and 50. By iteration of the process you will finally find the best setting.

    The Lebanon was the second clock that I had purchased, got it at the Portland Oregon Regional in the late 80's. It still runs like a champ and keeps great time. Mine was also missing the drop finials but methinks like the others they were either broken or lost.

    Many jewelers have a fuse welder. This is often called a spot welder. It should be rather straightforward to pry off the old hand, fashon a new pointer and have it spot welded to the front top surface of the hub area. A small 'bobbie pin' (ladies hair pin) will have the right temper and thickness but you may have to make it narrower to match the opposite side. Take some extra pieces of the 'bobbie pin' stock with you to the jeweler, so they can dial in the machine.

    BTW, this is mainly a selling feature and really adds nothing to the functionality of the clock.

    Thank you, Steven.
    Yes, those finials are missing. The one on the left was clearly broken off, so I'm guessing they removed the one on the right to make it look right.

    I believe that you are correct. This bob is very sensitive. I'm used to turning the rating nit, and the time will change around 2 minutes per day per turn.
    One turn on this will gain about 5 min per 12 hours. Now I'm just moving it just a tiny bit, and it's getting dialed in nicely.
