Application filed July 13, 1900. Serial No. 23,588. (No model.)

To aZZ whom it may concern: 3 is a cross-section of the attachment-body. Be it known that I, COLUMBUS PHILLIPS, a upon line C D of Fig. 1, and Fig. 4 is a view citizen of the United States, residing at Meridof a modified form of a safety-valve. ian, in the county of Lauderdale and State of In the embodiment of my invention all of 55 5 Mississippi, have invented certain new and the parts are inclosed within a body or shell 1,

Fig. 2 is a vertical which is provided with a stem 18, threaded section thereof upon lineA B of Fig. 1. Fig. through the nut 19, screwed into the top of rotating the stem and adjusting the vertical position of the said valve.

To prevent leakage when the valve 17 is open to its maximum width, I have provided I a valve 22 upon the back of the valve 17,

which engages with the seat 23 in the nut 19 when said valve has been opened to its limit and effectually prevents the escape of any water or steam through the said nut.

Removably fixed to the lower end of the= body 1 by the nut 24 is a bushing 25, having a flange 26 lhereon, against which the inwardly-projecting flange 27 upon the nut 24 engages and secures the said bushing to the lower end of the said body, the angular faces 28 forming a water-tight connection. The bushing 25 is threaded within a collar 29, which is secured, preferably, to the boiler 30 by means of rivets 31, and threaded to the lower end of said bushing 25 within the said boiler is the hood or elbow 32. Movable vertically within the bushing 25 and hood 32 is a safety-valve 33, having an upper stem 34, fitted into a lug 35, integral with the bushing 25, and a lower stem 36, fitted into a boss 37, integral with and projecting into the said hood. .A valve-seat 38 is provided for the safety-valve 33 within the bottom open end of the bushing 25.

A modified form of safety-valve is shown in Fig. 4, having a knife-edge 40 and no angular seat, as 38. safetyvalve insures a positive water and steam tight joint and a perfect seat, even though scale has formed upon the valve-seat in this case the bottom of the bushing 25.

This attachment can be secured to either the forward or the rear end of the boiler, and if attached to the rear end the water is conveyed to the forward end through the pipe 39, which is threaded into the hood or elbow 32, as shown in Fig. 1. If the attachment is secured to the forward end of the boiler, the use of this pipe 39 can be dispensed with. The usual form of feed-water injector is used with my attachment and connected thereto by the pipes 10 10. v

The operation of .my device is as follows: The valve 17 is lifted off its seat by means of the handle 21, and the Water from the injectors enters the inlet-passages 8 8 through the pipes 10 10, lifts the check-valves 12 12 off their seats, and the water enters the chamber 3,'passes through the aperture 5 into the chamber 4, down through the bushing 25 into the hood 32, and from there is discharged into the boiler. chamber 3 passes into the cooling-chamber 6, surrounding the central core 4:, and has a tendency to keep cool the adjacent parts.

arranged and refuse to seat properly when This construction of a" A portion of the water that enters the it or from any other cause, the safety-valve 33 will be raised automatically against its seat 38 by the excess pressure in the boiler and prevent the water or steam within the boiler escaping therefrom, and if perchance the device should be broken off or injured through a collision or fro|n other means the safety-valve 33, which is within the boiler itself, will beheld against its seat by the boilerpressure and the steam or hot water cannot escape at this point. If it is desired to examine the check-valves at any time, it is simply necessary to close the valve 17, as shown in Fig. 2, and thus out off all communication with the boiler-pressure, and by removing the nuts16 access can be had to the said valves, an operation requiring but little time and labor. The pipe 7 is designed for a squirt-pipe, and the Water that is conveyed therethrough from the cooling-chamber 6 is used for wetting down the coal and sprinkling the deck. it-is desired to use the squirt for only asmall amount of sprinkling, it will not be necessary to start the injectors, as sufficient Water will remain within the cooling-chamber to supply the demand; but if alarger amount of water is required the injectors must be operated.

There are many minor changes and alterations that can be made within my invention,

and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of my invention.

Having described my invention, What I .claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character described constructed with a body member provided with separate inlet and outlet chambers having connection with each other by means of a suitable port, and inlet-passages opening at one end through the said body member and at the other end into the said inlet-chamber; the combination therewith of a valve adapted in its movement to cover and uncover the said port; and check-valves operative within the said inlet-passages and normally closing the inner ends thereof, substantially as described.

2.

3. In a device of the character described,

constructed with a body member provided Should the check-valves 12 12 become dis- 1 with separate inlet and outlet-chambers connected with each other by a suitable port; and inlet-passages opening into the said inlet-chamber; the combination therewith of a valve adapted to cover and uncover the said port and in its open position to be moved in a plane above the openings of the said inletpassages into the said inlet-chamber, substantially as described.

4. In a device of the character described, constructed with a body member provided with separate inlet and outlet chambers connected with each other by a suitable port; and inlet-passages opening into the said inlet-chamber; the combination therewith of a valve adapted to cover and uncover the said port and in its open position to be moved in a plane above the openings of the said inletpassages into the said inlet-chamber, said valve carrying upon its back a valve, adapted when wide open to engage with a valve-seat upon the nut through which the valve-stem passes, substantially as described.

5. In a device of the character described, a body member having an outlet-chamber, an inletchamber above said outlet-chamber and connected therewith by means of a suitable port, and a cooliiigchamber surrounding the said outlet-chamber and opening into the said inlet-chamber; the combination therewith of a valve movable within the said inlet-chamber and adapted to cover and uncover the said port, substantially as described.
