Application led January 16, 1911. Serial No. 602,880.

leading to a flue cleaner; in the construe-- tion, arrangement'and combination of the separating devices, and in the combining with the separator of the shut-oill valve for the steam; and in the construction and arrangement of the valve to act as a drain valve for the separator when the steam is shut oit as more fully hereinafter described and particularly. pointed out ,in the claims.

in the drawings,-Figure l is a vertical central section through a separator embodying my invention;l and Fig. 2 is a side ele vat-ion, the lower part being in section.

The separator comprises a casing A, of

substantially bowl-shape, and a removable Y top B, the two being screwed or otherwise secured together. At the bottom is apassage C extendingacross the bottom of the bowl. and leading up the side, and discharging into the body of the bowl through the port a near the top. The upper edge of this port preferably has the lip b, which tends to deflect the steam slightly downward, and also slightly overhangs the wall c ofthe passage so that drip from above will not drop into the steam passage. In the top of the bowl is the concavo-convex diaphragml), lying preferably within the top and spaced from the side walls by the spider E, which has a ring F resting on a shoulder ot the bowl near the top, and is clamped in po,- sition by screwing the top against it, as plainly to be seen in Fig. 1. This diaphragm terminates in a hollow drainage nipple G, which depends to near the bottom ot the bowl, centrally thereof. It is also preferably provided with one or more apertures ai. The top has a central outlet nipple lll, to which the outlet steam pipe is connec-ted and has an inwardly-extending portion I which forms an inverted trough-like passage in the upper section of the tep. The

wall of this passage is stepped'l or corrugated as shown at J.

Acrossv the steam inlet passage C is a cross bore, in whichvis secured by a suitable gland e the plug cock K, having the cross port L,I

which may be brought into alinement with the steam passage, or, when the steam' is shut off, w1th`the ports c in the bottom of ,thevbowL and below the coc-k. This latter port connects preferably with a drain pipe L.

The parts being thus constructed, they are intended' to operate :1s-follows: The device is intended primarily to be inserted in the steam pipe leading from the steam down to a flue cleaner, being below the cleaner so that all water will drain from the cleaner int-o the bowl. The cock being opened, as shown in Fig. l, steam will pass through the passage C and enter the bowl through the port a. The water in the steam will fall into the bowl and settle in the bottom. The

.,steam will then pass through the spider around the diaphragm, impinge against the stepped walls of the passage in the upper portion of the top, be deflected downward by the inwardly extending nipple portion B1, and inally. pass out through the exit pipe. Any water in the steam which leaves the bowl will tend to be separated in impinging on the stepped walls ot the passage in the top, and in the bowl ,portion of the diaphragm, and will drain through the nipple G into the bowl. Thus, wet steam w'ill be largely treed from its water in passing through the separator, before it reachesthe flue cleaner. Water or wet steam it injected into the tlues tends to cake the soot and render it impossible to remove, while dry steam does not have 'this etli'ect.

It will be seen that in this structure I combine a steam shut-off valve with the separator, and thus dispense with the neces sity of another valve for the steam shut-off.

What I claim as my invention is,-

l. In asteam separator, the combination of a separating chamber having a steam passage leading therein and a drainage porttherefrom, and a single valve for controlling the steam passage and drainage port.

2. In a steam separator, the combination of a bowl forming the separating chamber, a steam inlet passage extending across the bottom of the bowl and up to the top of the bowl, the bowl having a drainage port at the bottom, and a single means for controlling the steam passage and drainage port.

3. In a steam separator, the combination of a bowl having an inlet passage opening into one yside thereof near the top, a `diaphragm centrally positioned within the bowl above the planeof the inlet opening and spaced from the sides of the bowl, a

curved ldeiector extending above the inletl trough-shaped steam passage, annular steps or corrugations in the wall of said troughshaped passage, and a central drainage tube depending from said diaphragm to substantially the bottom of said bowl.

4. In a steam separator, the combination of a bowl having an inlet passage opening into one side thereof near the top, a diaphragm centrally positioned within the bowl above the plane of the inlet opening and spaced from the sides of the bowl, and a central drainage tube depending from said diaphragm to substantially the bottom of said bowl.

5. A steam separator, comprising a casing having an inletpassage at the side opening into the casing adjacent the top thereof, and

a curved deflector positioned at the upper end of the inlet passage and extending above,

the opening in the casing and beyond the inner wall of the passage.

In testimony whereof I aix my signature in presence of two witnesses.
