This photograph is taken looking upward.
The bell-bars and metal strikers hang downward, below the small
valve chest that operates the unit, which is the opposite of how
the bells unit may appear to be oriented in this picture.
Each metal hammer is mounted on a long piece of spring steel.
Near the place where it attaches to the pneumatic motor it butts
up against a felt pad, so that the hammer cannot rest against
the bell-bar after the initial forward strike, permitting a
beautifully resonant and ringing tone. |
