Alarum, or Cooking Clock

By the aid of this little alarum the housewife will be able to time her joints, pies, and puddings, to an instant.

By winding it up and setting the hand back, starting from twelve, to the time required for the article to cook. Say it is one, and your joint is to be done at three,—move the hand to ten, wind up the spring, and place the box on the table, giving at the time an impulsion to the pendulum.
