Rack & Snail Strike (Mauthe wall clock)
How the rack and snail strike works in a mechanical pendulum clock, using a German Mauthe wall clock from the 1920s or 30s.

omg. I've been searching for exactly this kind of clock movement to properly reassemble what seems to be a 'Hermle'. I can't find this exact replica under that brand. I think I read that those predating the 40s weren't given serial no, just the pendulum length is engraved. Good thing it seems German clocks are alike. idk if it's a knock off nor do I care for the authenticity, I want to get it running again haha.
@Miriam Suzanne Not quite moving hands forward is safe... I had a few times situation where mechanism with rack and snail got jammed after moving hands forwad, so its safer wait until it stops...
Newbie with lots of questions: Thanks for this explanation. I have the exact same movement in a Mauthe wall clock, I noted that at some point there is lateral movement of the snail (perhaps to reset something ???) Can you explain this ? Also every once in awhile the rack will fall out of place and the clock will chime 13 times. It seems to reset itself after this happens however. One last thing, is there a way to speed up the rate that it chimes ?
apparently you don't respond to questions. Thanks anyway
Hope you will do more of these. You have a gift for clarity of expression which carries over into your camera work. Very nicely done!
I understand how the snail dictates the number of strikes af each hour by controlling how far the rack falls, what I don't get is how you only get one strike at each half hour? What dictates this please?
Good question! There are a few things to note here: - The two points on the center cam have slightly different shapes. The smaller one is used for the half hour strike. - The mechanism reaches 'warning' state (preparing the strike to run) before the rack hook moves out of the way, dropping the rack. The smaller point on the center cam only pushes the lifting lever high enough to release the warning wheel, but not so high that it drops the rack. Since the rack is held in place, the gathering pallet can only make a single rotation before it catches the hook.
The very best description and part naming and how to on youtube!!!! I learned more in 9 min. than the last book on mechanical clocks I just finished. Much thanks!!
Best video for detail about the base mecanic of the clock and how to set them! Thanks
Best video i have watched so far explaining the strike mechanism😊
❤🎉
Wanted a handbook for enfield clock hall (1950) for learn repair, thanks😊
