An endless apron carrying and feeding the straw t Compressd Air Engines in Tunnels. Bleaching of Silk. ELECTRICAL APPARATUS FOR STOPPING STEAM ENGINES. The object of this invention by Duncan Bros. London is to automatically close the valve of a steam engine and therefore stop it and to do this in the quickest possible manner the inventor has had recourse to a very simple elec trical expedient. The apparatus shown in Fig. 1 consists of an electro-mag net battery and wires leading to any position from which it may be desirable to control the engine and press buttons for completing the circuit. Also a small steam cylinder piston and rack and pinion gearing which actuates the stop valve on the engine. may be seen more plainly in Fig. 2 to a suspen sion rod which actuates a small steam cock on the cylinder of the apparatus. When it is de sired to put the apparatus in operation the press ure of the finger on one of the buttons—at any distance from the engine—closes the circuit ex cites the electro-magnet and causes it to lift its armature and release the suspension rod which falls with a velocity due to its own weight. The suspension rod in falling opens the small cock on the cylinder and admits steam the initial pressure of steam being the same as in the steam engine cylinder. The piston in the cylinder of the apparatus immediately ascends and the rack piston rod instantly closes the engine stop valve. The steam to work the apparatus being taken from the stop valve chamber from underneath the the stop valve has been closed there is no longe
