The cylinders c are each inclosed in' a water-jacket c3, supplied y with 'Water from a pipe c, provided with a. suitable valve c5, Within easy reach ofthe operatorvwhen Ion any one of the controllingplatforms'H, which are located at one side 'of each engine.

The gas-'engines inthe present instance are started by 'means of compressed air admitted to one of the cylinders oi' each unitthrough a pipe c', having a valve c' withinreach of the operator when on the platform H. .The pipes c lead from the air-cylinders K at one end of the building to each gas-engine unit. The air is forced under high pressure into the compressed-air cylinders by air-compressors K', two in the present instance, driven from ity than the engines I) to D, inclusive but other means of compressing air may beused without departing from our invention.

Each gas-engine has suitable regulating and governing devices tomake it of rate at. a constant speed whether the pump f l. ided or light.

In thepresent instance an electric igniter. is used for each cylinder of the engines; The igniters are controlled by switches It h It, on the switchboard H', mounted on the platformH.' "l

In order to insure the v`proper working of the sparking mechanism, we have so designed the apparatus that a primary or storage battcry can be used or the vcurrent canbe taken from a dynamo J,"drive`n from oneof the auxiliary gas-engines, or the eurren t may be taken from an outside source ol' supply, thus insuring an uninterrupted current.

Each pump unit A[has an independent suc# y tion-pipe IC extending7 into the extension'l or sump a of the conduit A, andthis pipe E hasy a foot-valve E and screen e'.

Between the valve fand fthe pump is a check-valve f which opens .toward the main.

N is the over-fiowspipe, forming a communication Ybetween the'pump and the wastepipe G, which acts as a bypass when the pump is i'rst set in motion, as it will be understood that the. pump does not immediately pump water into the main B, but pumps it through the overflow-pipe into the suc tionconduit or to waste. 'lhe overflow-pipe is provided with a gate-valve n, which in the sscgess parlaient instanoes operated by an electric mol-.cr n', the armature-shaft of the motor being geared to a wheel on the' valvestem, as
