LUDWIG. HAINZ, PRAGUE, CZEKOLSLOVAKIA, c. 1912

Single train.  Cast iron, plate and spacer frame. Pinwheel escapement with bolt and shutter maintaining power. One second pendulum with lenticular bob. 14"w x 23"h x 14"d.

The frame ornamentation and beautifully made pilot dial dial make this one of the nicer examples of tower clock from Checkolslovakia. Note the curious way the bushings are attached to the frame. The square bushing holding the main wheel arbor is horizontally split to facilitate the removal of the main wheel and its' barrel without disassembly of the lower frame.

The clock employs a safety system in the form of a ring at the top of its' pendulum to prevent the pendulum assembly from crashing to the ground in case of a suspension spring failure. It also employs a crutchless system by which the escapement pallets are directly mounted to the pendulum rod. The reasoning was to eliminate errors due to any 'sloppiness' in the connection of the crutch pin to the pendulum.  The crutchless system was used extensively in German and other Eastern European clocks where a pinwheel was used as the escape wheel. The suspension spring safety system was also used in many European tower clocks of all designs. Neither of these features were ever popular in America or England. The only exception I know of is an example by Mathias Schwalbach, although he was a German immigrant and was no doubt influenced by his experience in his native country. Other examples of the ring safety system are on two other German made clocks, Horz 2 and Horz 3 train models. Note the crutchless system unique to the Horz company on the 3 train model.
