STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 706,563, datedAugust 12, 1902.

Application filed January 27,19oz..se1-a1N0. 91,342. (No model.)

To all rah/0771, it may concern;

Be it known that I, JOHN J. HOPPES, a citizen of the ,United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvementsin Steani Boilers, of. which the followingiis a specification.

My invention relates to steam-boilers, and more especially to devices for producing dry steam from the outlet or steam-discharge of the boiler.

In theconstruction of steam-boilers the use of steam-domes has been largely dispensed with, and where ample steam-space is allowed above the tubes or water-line this may reasonably be done; but even then someprovision should be made to insure .dry steam. The current created bythe discharge of the. steam through the outlet has a tendency not only to draw the moisture or entrained water up the inner sides of the shell to the outlet, but also when the Water is boiling and violently agitated to lift it directly toward the opening; and the object of my invention is to provide means to check this tendency and drain the water back below the water-line. I attain these and other objects'bythe con: structions and combinations hereinafter described, and set forth in the accompanying drawings, in which Figure l is a transverse section ofa portion of a tubular boiler embodying my invention. Fig. 2 is a longitudinal section of a portion of a steam drum of a water tube boiler, showing my device attached to a boiler that has been in use; and Fig. 3 is a detail of this attachment.

Like parts are represented by similar let-L ters of reference in the several views.

In the drawings, a represents the shell, to. which the saddle-flange a of the discharge a is riveted. The lowerinner portion a of the discharge is counterbored and screw-threaded to receive the upper end of the inwardlyextending nozzle 1), so that the bore of the discharge and the nozzle will come flush with each other, asshown in Fig. 1. The lower portion of the nozzle b is flared outwardly and upwardly, forming a gutter I), having an outlet tube or pipe 6 extending below the water-line c of the boiler for the purpose hereinafter mentioned.

The disk d, which is preferably made with the side walls d"in the form of a pan, as shown in Fig. 2, is journaled to thepipe b and supported by the collar 01*, having the set-screw d The lower portion-of thejournal of thepan and the up'per portion of the collar on which itirests are beveled, so that when the disk or pan is turnedto one side to permit passage through the boiler for inspection and cleaning it will turn back into its position under the nozzle and the outlet d from the pan will register with the opening 6 in the pipe 79 to drain the pan, The journal of the pan is extended upwardly at b sufficiently to permit its turning on the beveled collar and yet prevent the'pan from rising to close the nozzle-opening.

In Fig. 11 have shown the preferred form of attaching the nozzle to the discharge; but

where the boiler has already been made and the discharge attached I provide the upper end of the nozzle with a laterally-extending flange 5 having a groove 1), in which I place rope asbestos or some other suitable packing extending beyond the face of said flange, so

that whenthe flange is bolted to the shell a by thebolts a the packing will form a water and steam tight joint (1 as shown in Fig. 3.

The tendency of moisture or entrained wa ter is to follow the walls of the shell, and it will be seen that by means of the nozzle it is intercepted and carried into the gutter and is piped below the water-line, and, further,when the water is boilingand violently agitated it is likely to be lifted 'or drawn by the current of the discharge,and this is prevented by the disk or pan, which also gathers the moisture or water'and pipes itback below the waterline. Thelpipe 12 preferably extends above the bottom of the gutter b, so as to retain a certain amount of water in the gutter to assist in gathering the entrained moisture or water. i

I have shown my device attached to a tubular and a water-tube b'oiler; but itis obvious that it may be employed in any style of a steam-generator, and whileI have shown only two modes of attaching the nozzle it is equally obvious that it may be attached in other ways, and I do not wish to be understood as con fining myself to the particular style of boilers and attachments shown.

2. In a steam-boiler, the combination with the steam-discharge outlet, the nozzle and a gutter on said nozzle with a conduit-pipe extending below the water-line as described, of a pan supported by said pipe extending between said nozzle and the water-line in said boiler, and having an outlet to said pipe, substantially as specified.

3. In a steam-boiler, the combination with the steam-discharge outlet, the nozzle and a gutter on said nozzle with a conduit-pipe extending below the water-line as described, of a pan journaled on said pipe with an outlet thereto, said pan normally extending between said nozzle and the water-line in said boiler, means to support said pan and automatically return it when it has been moved from its normal position, substantially as specified.

4: In a steam-boiler, the combination with the steam-discharge outlet, the nozzle and a gutter on said nozzle with a conduit-pipe ex- 7 tending below the water-line as described, of a pan journaled on said pipe with an outlet thereto, said pan extending between said nozzle and the water-line in said boiler, having the lower end of its journal beveled, and a supporting-collar on said pipe having a corresponding bevel, means to fix said collar on the pipe, and means to limit the movement of said pan toward the nozzle, substantially as specified.

5. In a steam-boiler, the combination with the steam-discharge outlet, of a pan extending between said outlet and the water-line in said boiler and a conduit from said pan extending below said water-line, substantially as specified.

6. In a steam-boiler, the combination with the steam-discharge outlet, of a pan normally extending between said outlet and the waterline in said boiler, and a hollow support for said pan extending below the water-line in said boiler, said pan having an outlet to said hollow support, and means to automatically return said pan when moved fromits normal position, substantially as specified.

In testimony whereof I have hereunto set my hand this 22d day of January, A. D. 1902.

JOHN J. I-IOPPES.
