Application filed April 6, 1912. Serial No. 688,979.

away, showing the application of my invention to a water column, as a high and as .a low water alarm, and also as a feed water regulator; Fig. 2 is a view similar to Fig. 1, but showing the application of the invention as a feed-water regulator onlyg Figs.

3 and 4 are sectional views showing the device as adapted for a combination gage cock and low water alarm, the planes of the two sections being at right angles to each other; Fig. 5 is a view similar to Fig. 3, but showing the device as adapted for a high water alarm; and Fig. 6 is an end view.

My invention has relation to combination gage cocks and high and low water alarms, and is designed to provide a simple and eflicient device of this character which can be readily adapted for use either as a high or as a low water alarm.

My invention also provides a device which is capable of use as aregulator for feed water pumps, etc.

The nature of my invention will be best understood by reference to the accompanying drawings, in which I have shown the preferred embodiment thereof, and which will now be described,'it being premised, however, that various changes can be made in the details of construction and arrangement of the several parts, without departing from the spirit and scope of the invention as defined in the appended claims.

In these drawings, thenumeral 2 designates a water column, which is in general of the usual character, and which is shown in Fig.1 as having a threadedboss 3 for the attachment of the high water alarm, and asimilar boss 4 for the attachment of a low water alarm.

The alarm device comprises abody 5havtacle 8, which is designed to contain some fluid which will expand and contract under variations in temperature. The neck portion 9 of this bulb has an opening 10 communicating with the interior of the bulb and also leading into a diaphragm chamber 11 at one side of a diaphragm 12, which is held at its peripheral edges by the bolting flange of thecap .6. Attached tov the diaphragm is a stem 13 which extends within thebody 5 and carries avalve 14. This valve controls aport 15 in a diaphragm orpartitionwall 16 placed within achamber 17 in said body. One end of thechamber 17 is at all times connected with the interior of the water column by a port orpassage 18 which extends through thebody 5 and through thecap 6. The other side of thechamber 17 communicates by asuitable pipe connection 19 with analarm whistle 20, in the arrangement shown in Fig. 1.

The stem 13 is provided with asuitable packing 22 within thebody 5, this packing has a spring 23 seated against it and against an adjustingring 24, and anotherspring 25 is seated between the opposite side of this ring and diaphragm 12.

Theend cap 7 has aport 26 normally closed by ahand valve 27 and connecting one end of thechamber 17 with a blow-ofi' 28. This blow-oft 28 is shown as extending into a pipe ornozzle 29, which communicates by aport 30 with the air side of the diaphragm chamber 11.

Supposing the device to be arranged as a 'low water alarm, as in Figs. 3 and 4, the

operation is as follows :As soon as thebulb 8 becomes uncovered with water and is subjected to the action of steam in the water column, the expansion of the liquid contained therein is suflicient to actuate the diaphragm 11 to open thevalve 14, and therebyadmit steam through the port 15' andconnection 19 to the alarm or whistle.

To adapt the device for'use as a high water alarm, thevalve 14 is shifted on the stem 13 t0 the opposite side of thediaphragm 16, as shown in Fig. 5. In this arrangement, when thebulb 8 is covered or partly covered with water, a contraction of the liquid contained therein will takev age or condensation in the air side of the diaphragm chamber will be siphoned or drawn oft at thenozzle 29 through theport 30. V

The device as shown in Figs. 3 and 4: can be adapted for use as a feed water regulator in the manner shown in 2. WVhen so used, apipe 31 is attached to theconnection 19, and is extended to a device for operating a control valve in the feed water supply pipe. In so far as the present application is concerned, any suitable device may be used for this purpose. I have, however, in Fig. 2, indicated a particular form of device which forms the subject-matter of a co pending application Serial No. 688,978 filed April 6, 1912. This device is shown as consisting of acylinder 32 having a piston 33 therein below which thepipe 31 enters. Thestem 34 of this piston is connected to theweighted lever 35 of a control valve, which is located in thecasing 36 in the feedwater supply line 37. The weighted lever normally maintains its valve closed; but when the steam is admitted to thechamber 17 and thence to thepipe 31, the piston 33 is actuated to open the valve and to hold it open until the water level in thecolumn 2 is again restored to normal. 7

My invention may also be readily adapted to control the operation of pump regulators and similar devices.

The advantages of the invention result from the simplicity of construction; from the fact that the device can be used with little or no change for a variety of different purposes; that it is efiective and reliable in its operation; and that it can be manufactured and sold at a relatively low cost. It also does away with the use of floats and float-operated connections such as areusually employed in devices of this character, and which are open to various objections.

That I claim is 1. In a device for actuating high and low water alarms and feed-water regulators, the combination with a water container and with a device to be operated, of a controlling device comprising a casing having means for its attachment to the container and also having a steam escape passage opening into the interior of the container and also connected with the device to be operated, a valve for controlling the passage of steam from the container through said passageway to the device to be operated, a, diaphragm chamber in the casing, a diaphragm in said; chamber, an actuating connection betweenthe diaphragm and the valve, and thermostatic means carried by the casing and adapted to cause the actuation of the diaphragm; substantially as described.

2. The combination with a water container, of a casing connected thereto and containing a diaphragm chamber, a diaphragm 1n sald chamber, a valve connected the container and having its interior communicating with the diaphragm chamber at one side of the diaphragm, the casing having a vent port leading from the opposite side of the diaphragm chamber, substantially as described. V

3. In a device for actuating high and low water alarms and feed-water regulators, the combination with a water container and with a device to be operated, of a controlling device comprising a casing having. means for its attachment to the container and also having a steam escape passage opening into the interior of the container and also connected with the device to be operated, a valve for controlling the passage of steam from the container through said passageway to the device to be operated, a diaphragm chamber in the casing, a diaphragm in said chamber, an actuating connection between the diaphragm and the valve, and a bulblike receptacle connected to the casing and projecting within the container, the space within said receptacle communicating with the diaphragm chamber and being designed to be filled with an expansible fluid; substantially as described.

4. The combination with a water container, of a device for indicating or controlling the water level in said container, said device comprising a casing having means for its attachment to the container, the casing also having a steam passage leading therethrough from the interior of the container and communicating directly with the interior of the container at one end, a valve for controlling said passage, a device connected to the outlet end of said passage to be operated by the steam escaping therethrough when the said valve is opened, and means controlled by the water level in the container for actuating the valve, substantially as described. a

5. The combination with a water container, of a device for indicating or controlling the water level in said container, said device comprising a casing having means for its attachment to the container, the casing also having a steam passage lead the casing for actuating the diaphragm, sub- 10 stantially as described.

In testimony whereof, I have hereunto set ing therethrough from the interior of the container and communicating directly with the interior of the container at one end, a

valve for controlling said passage, a device my hand.

connected to the outlet end of said passage to be operated by the steam escaping there- WERNER STAAF' through when the said valve is opened, a Witnesses:
