Reconfiguration of  strike system

         Brass 3 train (19).JPG (580467 bytes) The bell hammers were on extremely long levers. These were powered by very strong springs. This set up required a great deal of power. It is possible that the bells were mounted somewhere above the clock, perhaps on a separate support, a case or even from a separate stand. There was an attachment for the bells screwed to the pendulum support bracket (center black colored bracket). This was too short for the bells to align with the hammers. The bells being attached to the same system that supports the pendulum presented problems in that they are heavy and the vibrations produced by their being struck would cause serious errors in time keeping.

Such a support needs to be as ridged as possible. Mounting bells to such a system would be unwise. As it is, we had added additional center cross braces to increase the stability of this structure.

Brass tower clock-Saff (42a).jpg (625656 bytes) The rest of the photos show the revised design. Here we tucked the levers within the boundaries of the strike frames. The hammers are fully adjustable to vary the loudness of the strike. Large, soft leather heads are employed to moderate these large bells as this clock will be used in a domestic environment.
