Something mechanical for a change. This ‘Klingsor’ phonograph (record player) dates from the early 1900s and has no electrical parts yet plays old 78 rpm records at a surprisingly loud volume. It had a fault which prevented it from being wound up. Rather than a ratchet to hold spring tension, as found in clocks, it has a small spring which locks around the winding shaft preventing it from unwinding. If this fails during a wind up it’s likely to painfully rap the knuckles of the winder. It is however, an interesting method, it's silent and avoids any annoying clicks while winding up with a record playing.
