JOHN W. SULLIVAN, OF NEW YORK, N. Y., ASSIGNOR OF THREE-SIXTEENTHS TO FRED W. PARKINSON AND THREE-SIXTEENTHS TO W. M. HATCH, 013 NEW YORK, N. Y.
INDICATOR AND ALARM.
Specification of Letters Patent.
Patented Mar. 4, 1913.
Application filed May 24, 1-912. Serial No. 699,426.
1'0 alt whom, it may concern.
Be it known that 1, JOHN W. SULLIVAN, a citizen of the United btates, residing at New 1' ork, in the county of New lork and State of N ew I'ork, have invented new and useful improvements in indicators and Alarms, of which the following is a specification. 'l'his invention relates to indicators and alarms for indicating the height of water in tanks, vessels and the like and for automatically sounding an alarm when a predetermined level has been reached.
The invention has for its object to produce a device of simple and improved construction which may be readily applied to Ships for indicating the height of water in the hold' in the event of leakage and for sounding an alarm in ample time to givewarning if the water should reach the danger mark.
A further object of the invention is to produce a device of the class described which shall be simple and inexpensive, easily installed and perfectly automatic in its oper-. ation.
With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.
In the accompanying drawing has been illustrateda simple and preferred'form or the invention, it being, however,'understood that no limitation is necessarily made to the precise structural details therein exhibited,
' but that changes, alterations and modifications'within the scope of the claim may be resorted to when desired.
In the accompanying drawing,- Figure 1 is a sectional elevation showing the improved device installed. Fig. 2 is a detail view in elevation illustrating a slight modificati'on.
Corresponding parts in .both figures are denoted b like characters of reference.
In the hold A of a ship, adjacent to the bottom thereof, is placed an inverted bell or vessel 1 having lugs forming feet 2 whereby the lower edgeof the bell is slightly elevated above the floor to which the bell is securely connected by fastening members, such as screws 3, engaging the floor through the lugs 2. Connected with the closed top of the bell and engages one end of a trip lever 12, the
opposite end of which has a tooth l5 arranged in the path of a trip device, such as the wrist 14 01 a wheel 15 rorming one of a spring actuated train inclosed within a casing striker 17 adapted to engage a bell 1:5 for the purpose of sounding an alarm.
it is desired to be understood that the alarm device may be of any suitable and de- 16 for the urpose of actuating the sired type and construction, and for the purpose of making this clear there has been shownin Fig.2 an alarm bell 19arranged in a circuit including a battery 20 and adapted to be closed by the trip lever 12 when the latter is actuated to a certain predetermined extent, thereby sounding the alarm.
It will be readily understood from the foregoing description that the improved device may be readily installed in the hold, or
in one or more compartments of a ship and I that, in the event of a leak, the water rising within the hold or compartment and within the bell 1 will compress the air within said bell, the tube 4 and the branch 8, thereby actuating the indicator 6 of the gage 5 which is to be arranged in some conveniently accessible and conspicuous place where it may be consulted at a glance as often as may be desired. It will be understood that the units of the scale 7 may be taken to represent feet of water in the hold or that'other units of measurement may be adopted. The oflicers of the, ship will thus be enabled at any time to detect the presence of water in the hold before a danger line is reached. As a further precaution, however, the alarm device is provided which is so arranged that when the water reaches a predetermined height sufficient pressure will be created to alarm to be sounded.
Having thus described the invention, what I on the casing, and a post connected with the is claimed as new, is diaphragm and extending through the cas In a device of the class described, a bell ing to actuate the trip lever; in combination supported above the floor of a compartment with an alarm device actuated by the trip 5 and havingan upwardly extending tube, a lover.
