"Spiral spring" Quotes from Famous Books
 ... is closed by the action of the external distributing mechanism, the piston passes beyond the steam-outlet, A, and a new piston then comes in play. Altogether, there are six of these pistons, each one working in an aperture in the rim, and kept pressed outwardly by means of a spiral spring. The steam acts constantly on the same lever arm and meets with no counter-pressure. The other defects, likewise, of the ordinary steam engines in use are obviated to such an extent that the effective power of the steam-wheel ...

Certainly, there were great bill-toppers, creators of sensations who discovered new things—terrifying feats of gyroscopic balancing, or flights through space, based upon principles of ballistics, assisted by the spiral spring—daring risk-alls, nerve-shakers, purveyors of thrills, turning to intelligent account the seductive power which dangerous feats exercise upon the public. Jimmy knew all about that. He was not the only one; but, this time, it was a question of a scientific application ...

... of them. To effect this, the drum around which the chain winds that carries the carbons is mounted upon a sleeve fixed upon the axle. This latter is actuated by a winch; and a ratchet wheel, R, joined to a click which is actuated by a spiral spring, prevents the ebonite plates from falling back when it is desired to place the bolt under the button, ...
