ALBERT F. EELLS, OF BOSTON, MASS., ASSIGNOR OF A PART OF HIS RIGHT TO SAMUEL O. LOUD, W. H. DOLE, AND F. B. DOLE, OF SAME PLACE.
IMPROVEMENT IN BlLGE-WATE-R ALARMs.
Specification'formingpart of Letters Patent No. 184,851, dated November 28, 1876 application filed October 23, 1876.
- height in the ship and consists in combining,
with an alarm device and a mercury-column, a tube which extends to the hold of the ship, and terminates in a hell or water-chamber, the mouth of which opens downward, so that when the water rises above it, pressure is produced within the pipe, said pressure being transmitted to the mercury column, and through the overflow of the mercury to the alarm device. s
This device is not confined to ships use,
but may be applied to a variety of uses.
Figure 1 is an elevation of my invention. Fig. 2 is a vertical cross-section of the same. Fig. 3 shows a part of the let-01f device.
In this device, A represents a fixed water bell or chamber, having its open end downward, as shown in Fig. 2. To the upper part of this bell I attach the air-pipe B, which'communicates with the mercury siphon B B, Fig. 2. The ascending arm B of the siphon terminates in the cup or receptacle D, from which a pipe, E E, leads to the counterpoisecup K of the alarm-device let-off.
This alarm device will be foundfully described in Letters Patent of the United States granted to me, and dated August 22,1876,
No. 181,323, entitled Improvement in Fire- Alarms.
The operation of my device is as follows: When water begins to accumulate in the bilge it will flow upward into the hell or chamber A, and thus exert a pressure on the air in the bell A and tube B. This pressure will be transmitted to the mercury in the siphon B B and cause the mercury to ascend the arm B andthus indicate on the graduated scale C the amount of water in the bilge. A continued rise of water in the bilge will cause the mercury in B to overflow into the cup D, and thence through the pipe E E to the counterpoisecnp K of the alarm device, and thus give the alarm.
I claim as my invention- The combination of the water hell or chamber A, pipe B B,'siphon B B cup D, and
pose set forth.
