ALARM WATER-GAG E.

SPECIFICATION forming part of Letters Patent No. 380,881, dated April 10, 1888. Application filed January 9, 1888. Serial No.260,1-16. (No model.)

To all whom. it may concern. l

Be it known that we, GEORGE FIsHER and PETER RAPPOLD, citizens of the United States, of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in an Alarm Tater-Gage; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

Our invention relates to an alarm water-- gage, and is designed to indicate the accumu lat-ion of water in the hold of a vessel, and also to sound an alarm when the water rises beyond a certain depth.

The object of the invention is to provide a gage having adj ustability of parts as well as a flexible portion intermediate the indicator and float that shall not be affected by the movement of the vessel when rolling, and to attach to the gage an alarm that shall be caused to announce when water shall have accumulated in the holdto any depth to which the alarm is I arranged to operate.

The invention consists in a well extending from the bilge to the upper deck, and within which is a hollow float, preferably of oval shape, having a threaded rod passing through its major axis, the perforations in the float through which the rod passes being also threaded to allow the float to be adjusted upon the rod to any desired height, the upper end of the rod being attached by means of flexible connections to a revoluble disk having a central stud, to which is connected an indicator to mark the rise of water in the hold and an alarm mechanism caused to operate by being tripped by a cam or projection upon the central stud.

In the drawings, Figure 1 is a Vertical cen tral section of the well, the indicator being shown in front elevation. Fig. 2 is an enlarged detail view of the revoluble disk. Fig. 3 is an enlarged detail views, howing the tripping arrangement alarm mechanism. Fig. 4 is a plan View of the well on lines y 1/, Fig. 1. Fig. 5 is a detail view of the alarm mechanism.

A designates the well, )referably formed of tubular pipe B, the extension of the same consisting of a tubular pipe of smaller diameter than well A, and secured in cap F, at the top thereof, by being threaded at the lower end and screwed into a threaded perforation in said cap.

E designates a transverse plate secured centrally of the length and within the well, and provided with a perforation centrally of its diameter through which passes rod D, having at its threaded lower end a float, O, with a threaded perforation centrally of its axis, by which means the float is adj ustabl y secured to the rod. The upper end of rod D is formed with perforations, (preferably two,) for a purpose hereinafter stated. Upon the upper side of plate E are secured two grooved pulleys, T.

G designates flexible connections,with the rod D and an alarmgage secured at any convenient point upon the vessel. The flexible connection,whieh may be an ordinary cord or rope and consisting of two strands,which are attached each at one end to the upper end of rod D by being passed through the perforations and secured, and are then passed under pulleys T, the strands being separated and one passed under each pulley, and from thence through the well and extensionpipe B, at

l which point the strands are joined to form one cord or rope, which is secured to the periphery of a revoluble disk, H, having acentral stud, I, secured to the disk in such manner as to re volve therewith, the inner end of the stud be ing journaled in the hanger or board L, to which the alarmgage is attached, the opposite end revolving in a hearing within dial, N, and intermediate the two bearings having a cam or projection, P, the portion of stud extending outwardly from the dial having a pointer, M, attached thereto.

- K is a coil-spring attached to studl and to hanger L.

O designates a jointed lever having a catch, Q, adapted to engage and be locked in position with a stud, Q, upon hanger L. The horizontal portion 0 of jointed lever O is forked, and has pallets O engaging with a scapewheel, 0', connected by a train of gearing to an arbor havinga coiled spring woundthereon.

Since this portion of the device may be of any well-known form, itis unnecessary to illustrate the same further, it only being necessary that the scape-wheel 0 be connected, as by any well-known clock gearing and spring, to have a normal tendency to revolve and actuate the escapement when the catch Q of the lever O is released from the stud Q.

R designates a hammer connected with the train of gearing and caused to sound an alarm upon a gong, S, attached to the frame encircling the train of gearing.

P designates a lever fulcrnined at P and having an angled portion normally resting against the lever O, the opposite portion resting within the radius of travel of the cam or projection I? of the stud I when revolved.

In operation,when water accumulates in the bilge and enters the well through the perforations in the bottom, the float rises correspondingly, and by the connection of the rod D with the flexible connections and to the revoluble disk H revolves the same, causing the pointer to indicate upon the dial the depth of water in the vessel, and as the stud I continues to revolve with the further revolution of the disk the lever P is moved and trips the rod 0, thereby allowing the scape-wheel to revolve, the pallets of the forked lever O determining the revolution of the wheel as they alternately engage and disengage with the teeth of the scape-wheel, and the hammer R is caused to sound the alarm upon the gong S.

It will be seen that our device is inexpensive, and that by the flexible connection of the rod with the alarm-gage the gage may be placed in any convenient position on the vessel without regard to its relation vertically with the well.

The float being adjustable upon the rod on ables the device to be adjusted to indicate any desired depth of water, and by varying the point of attachment of the cord or rope upon the disk H a further adjustment of the indicator and alarm may be effected.

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s-- 1. In an alarm water-gage, a Well, a float adjustably secured to a vertical rod within the well,having a flexible connection with an alarm and indicator, as and for the purpose set forth.

2. In an alarm water-gage, a well, a hollow float therein adjustably secured to a vertical rod, in combination with an alarm mechanism, and ropes or like connections with the rod and alarm mechanism, as and for the purpose set forth.

3. In an alarm water-gage, a well, a float adjustably secured to a rod moving therein and through a transverse plate secured within the well, in combination with a disk revolving with a central stud having an indicator upon one end and a tripping-lug centrally thereof adapted to release an escapement connected with an alarm, and a flexible connection from the rod to the disk, as and for the purpose set forth.

In testimony that we claim the foregoing as our own we hereby aflix our signatures in presence of two witnesses.
