128 Shepherd, Charles, 53 Lead&nliall Street— Inventorand Patentee.

Patent electro-magnetic striking clock. From thependulum of this clock, a number of dials may be worked.The greatest novelty consists in the method of giving theimpulse by means of a remontoir escapement, by whichthe valuations of the battery take no effect on the timemeasured. The novelty of the Large Clock in the Transeptof the Exhibition Building, in connexion with the former,is in the method of locking the escape-wheel, to preventthe train from running by the action of the wind on thehands.

Two dials, five feet in diameter each.

A skeleton electro-magnetic striking clock, showinghow the number of blows to be struck is regulated.

Small turret bell, illustrating the method of applyingelectro-magnetism to move the hammer.

The power employed for keeping in continual actionthe electric clock is one of Smee’s batteries in connexionwith a powerful horse-shoe magnet. In the case of themechanism of the great clock now under consideration, aseries of such magnets is used, the connexion of which,with their armature, is shown in fig. 1. These are
