APPARATUS FOR SUBSTITUTING GAS FOR ELECTRIC LIGHTS.

SPECIFICATION forming part of Letters Patent No. 274,181, dated March 20, 1883.

Application filed August 21,1882. (No model.)

To all whom it may concern: as a cock revolved by a weight with one arm Be it known that l, PATRICK B. DELANY, that is arrested by a projection on the armaof the city and State of New York, have iuture-lever to hold the cock in a closed posivented an Improvement in Automatic Appation. As the armature-lever flies back this 55 ratus for Substituting Gas for Electric Lights arm is released and the weight turns the cock, and the Reverse, of which the following is a opens the same, and another arm is arrested specification. by the armature-lever and holds the cock open.
