Program
Disk where pins where placed to indicate the time when bells
would ring.
Toothed
Wheel which sits on top of the revolvable drum or switch.
See Figure 6 of the patent drawing for more detail and a
view from the top.
The
Revolvable Drum where pins were placed to engage the contact
arms at their "shoulders" or bend. Each pin could
control a 12 hour period. 14 pins would control a week which
would permit programs for 7 days and 7 nights. See Figure 7
of the patent drawings for a view from the top.
Contact
arms which would be raised at the free end when they engaged
with the pins in the drum. When raised ends came in contact
with the pin in the program disk the electric circuit was
closed and the bells would ring.
Escapement
Wheel
The
Spring Motor which provided the power to turn the program
disk so the pins set in it would be moved into position to
ring the bells.
Lever
with "V" shaped recess, which with the verge
determined how long the bells would sound. The lever arm
connected to a handle which was used to adjust the lever's
position. This was a way to control the duration of the
signal.
