[Illustration: Fig. 40.--Electric alarm releaser, as attached to separate
wooden clock casing.]
If the bell, battery, and clock are in the same room, a single dry cell
will give sufficient current; but if the circuit is a long one, or several
bells have to be operated, two or more cells will be required.
An Alternative Arrangement.--Should the reader prefer to have the clock
quite free from the release--and this is certainly convenient for winding
and setting the alarm--he should make a little wooden case for the clock
to stand in, just wide enough to take the clock, and the back just as high
as the top of the barrel. The release is then attached to a little platform
projecting from the back, care being taken that the lever is arranged in
the correct position relatively to the hammer when the clock is pushed back
as far as it will go (Fig. 40).
If a self-contained outfit is desired, make the case two-storied: the upper
division for the clock, the lower for the cell or cells. The bell may be
attached to the front. A hinged fretwork front to the clock chamber, with
an opening the size of the face; a door at the back of the cell chamber;
and a general neat finish, staining and polishing, are refinements that
some readers may like to undertake.
