STEAM-SEPARATOR.

Specification of Letters Patent.

Serial No. 385,599.

T 0 all whom it may concern:

Be it known that I, WILLIAM EDWARD STANLEY, a citizen of the United States, and a resident of Louisville, in the county of Jefferson and State of Kentucky, have invented a new and Improved Steam-Separator, of which the following is a full, clear, and exact description.

This invention is an improvement in steam separators as are ordinarily located between a boiler and an engine to insure a working of the engine under dry steam only.

The object, primarily, of the invention is to provide a simple construction of this nature which will remove from the steam substantially all the water, leaving the steam in an approximately dry state. This I accomplish by providing a vertical casing having a steam supply leading into its upper end, and a stand-pipe projecting upwardly from its base in connection with a steam outlet pipe. The stand pipe carries a tubular head preferably slightly tapered and provided with perforations upwardly and inwardly inclined, whereby the steam in passing therethrough, will shed the water, which will be discharged through the bottom of the casing.

Reference is to be had to the accompanying drawing forming a part of this specification, in which the figure therein represented is a vertical, central section of the preferred embodiment of my improved separator.

In the preferred practical construction of my improved steam separator, I employ a tubular casing or shell 10, having the oppo site ends thereof eXteriorly threaded, and on which are screwed flanges 11, the same being connected with flanges 12 as by bolts 13, said flanges covering the bottom and top of the casing, respectively. The casing, when disposed in operative position and substantially vertically arranged, has a steam supply pipe 14 leading into its upper end as by threading said pipe into the top flange 12, and a steam outlet pipe 15 connecting with and made as a separate part or integral with a stand pipe 16 threaded through the bottom flange 12, and projecting upwardly within the casing a suitable distance. Should the stand pipe be made separate from the outlet pipe 15, as shown in the drawing, I preferably connect their opposed threaded ends together by a coupling 17.

Threaded or otherwise secured to the upper end of the stand pipe 16 is the primary feature of my invention, the same consisting of a tubular head 18 preferably tapered to make it of conical form, with the enlarged end at the top, where it is provided with. an integral conical top 19. A series of circumferential, downwardlydirected, V-shaped grooves are formed in the head 18, through the bottom of which pass a number of upwardly inclined apertures 20, the combined sectional area of said apertures being preferably about twice the area of the cross section of the pipe 16. At the bottom of the casing 10 is a drain pipe 2 1, and at a point thereabove a water-gage 21 is connected at its opposite ends to the casing which, as shown, is provided with valves 22 and with a draincock 23 connected with the lower valve.

The steam, on entering the pipe 14, descends and passes through the several apertures in the tubular head 18 and thence through the stand pipe 16 through the outlet pipe 15. As the steam passes through the apertures 20, which are very small in diameter, the water in effect is squeezed out and is not permitted to pass within the head by reason of their upward inclination. As the water sheds from the apertures, it drops to the bottom of the casing without striking that portion of the head below it, on account of the slight taper given this part of the separator. The water, on passing to the bottom of the casing, is discharged through the pipe 24, which ordinarily connects with a steam trap (not shown). Should the flow of water through the pipe 24 for any reason become checked and not be discharged as rapidly as it is separated from the steam, it will be at once indicated by the water-gage 21.

The invention as shown and described, although being my preferred practical embodiment of my improved steam separator, may obviously be slightly modified within the scope of the annexed claims.

Having thus described my invention I claim as new and desire to secure by Letters Patent:

1. A steam separator comprising a substantially vertical casing, having a steam inlet at its top and a steam outlet in its bottom, a stand pipe of smaller diameter than the casing and projecting upwardly from the bottom into the same and forming a continuation of the steam outlet of the casing, and a tapering head having a conical top and secured at its smaller end to the end of the stand pipe within the casing, said head being provided with a plurality of circumferential combined sectional area of the said openings being about twice the cross sectional area of the stand pipe.

2. A steam separator, comprising a substantially vertical casing having a steam inlet in its top and a steam outlet in its bottom, a stand pipe of smaller diameter than the casing and projecting from the bottom into the same and forming a continuation of the steam outlet of the casing, and a conical head open at its smaller end and closed at the larger end and having its smaller end secured 15 clined apertures in the bottoms of the 20 grooves.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM EDWARD STANLEY. I/Vitnesses:

FREDERICK WILLIAM TAYLOR, TRAVIS KAVANAUGH.
