E. PLATT STRATTON, OF COLLEGE POINT, NEW YORK.

STEAM-SEPARATO R.

SPECIFICATION forming part of Letters Patent No. 375,463, dated December 27, 1887.

Application filed August 1, 1887.

To all whom it may concern.-

Be it known that I, E. PLATT STRATTON, a citizen of the United States, residing at College Point, in the county of Queens and State of New York, have invented certain new and useful Improvements in Steam-Separators, of which the following is a specification.

This invention relates to certain improvements in separators of the general construetion described by me in Letters Patent of, the United States granted August 4, 1885, No. 323,891, adapted for the separation of the condensed portions of steam which occur during the conveyanceof the latter from the generator to theconsuming-point.

The invention consists in certain improved features of construction relative to the deflecting-shield which surrounds the margin of the depending curtain or delivery-pipe nozzle of the apparatus, andthe combination therewith of a system of drainage, and of a diaphragm or preventer for the positive repression of the separated water in the trap beneath from the dry-steameduction current.

In order to enable others to understand and practice my said invention, I will proceed to describe the several features of improvement, explain the effect of the same with relation to the general operation, and subsequently point out the novel features in the appended claims.

Referring to the accompanying drawings, Figure 1 is a vertical central section of the complete apparatus, and Fig. 2 a plan View thereof; Fig. 3, an enlarged sectional view of the deflecting-shield and diaphragm; Fig. 4, a plan view of the same; and Fig.5, an enlarged sectional view of the base, showing a means of attaching the shield-supporting column thereto.

In the present instance the shell A is composed of two separable cast sections of cylyndrical form, the upper one having provided near its top a tangential steam-induction opening, a, and having connected also at its upper end the delivery or eduotion steam-pipe B, provided with a downwardly-projecting nozzle or curtain, b, the lower section of the appa-- ratus constituting the water repository or chamber 0, which, being of enlarged diameter and capacity, obtains a reduced velocity of steam-current at the point'where a change in its direction and a final separation from the water takes place. A suitable water-gage, e,

and a drainage-pipe, d, at the lowermost point of the concave base are also provided for the indication of the quantity of water accumulation or the occasional removal of the same, respectively. Such features are equivalent, and have like functions to those described in the patent aforesaid.

The improved deflecting-shield D is prefer- .ably of conical form, surrounding and extending a distance above and beneath the depending end of the nozzle or curtain b, and forming an annular steam and water passage, f, and a steam-passage, g, the latter being equivalent in area to that of the nozzle 5, for the purpose of admitting the main portion of dry-steam current through said passage'g. The lower edge or margin of the deflecting-shield D is provided with alip ,forminga channel, h, into which the Water carried by the current through the passage f is mainly deposited. The channel 7r is provided with drainage-tubes 73, passing through the diaphragm or preventer E to the trap G beneath.

The manner herein shown of supporting the deflectingshield and the diaphragm is found to be advantageous for readiness of removal or accessibility of the parts, the arrangement consisting in centering the deflectingshield by means of the projections j,cast thereon, the ends of which fit to the diameter of the chamber G, and sustaining the said shield,together with the diaphragm, vertically by means of the column F, the latter consisting, preferably, of a piece of tubing threaded at its top into the hub of the said diaphragm and at its lower end into the webbed casting G, constructed, as shown, so as to permit the waterdrainage and form a supporting-hub for said column.

As will be seen by Fig. 4, the projections j are placed coincident with the channel drainage-tubes 2', the said projections forming a part of said drainage-tubes and also serving as lugs for bolting the diphragm in place. The drainage-tubesi are carried in toward the center by means of the extensions, for the'purpose of delivering the water at a point remote from the steam-current, or said tubes may be carried beneath the waters level, if required.

In operation the saturated steam is introducedthrough the tangential orifice a into the cylindric space surrounding the nozzle or ourtai n 1), whereby a circular or downward-spiral motion is imparted to the current and the water particles thrown by centrifugal action upon the outer spacesurface, upon which it gravitates to the trap-chamber, passing outside the deflecting-shield D, while the current of steam follows the depending nozzle or curtain b to the interior of said shield and escapes in a dry state upward through the delivery-nozzle; but it is found expedient in practice to effect also a further positive separation of the portions of steam carried over with. the water to the exterior of the deflecting-shield. Herein occurs the function of the channel h, which, intersecting the downward flow of the saturated steam as it is thrown upon the cone-surface, collects the heavier particles or condensed portions,thesame escaping by gravity through the tubes 1', beneath the diaphragm E, and into the trap, while the drier portions are drawn through the space beneath said channel above the diaphragm E. The diaphragm or prcventer E is preferably made of the convex form shown on its upper surface, for the purpose of assisting in directing the steam toward the delivery-pipe, and also in order that the outflow of any water particles carried over may tend to discharge by gravity. This diaphragm E also prevents a volume of the water contained in the trapchamber G from being suddenly carried upwardly with the steam in the event of an unusual use of the latter, or occasioned when used for marine purposes by a rolling motion of the vessel.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a steam separator arranged to secure a centrifugal action to the steam, a deflectingshield surrounding the lower portion of the depending delivery-nozzle, and provided with an exterior marginal channel and a drainage tube or tubes, substantially as and for the purposes set forth.

2. In a steam-separator arranged to secure a centrifugal action to the steam, a deflecting shield surrounding the lower portion of the depending delivery-nozzle, said shield forming an internal annular orifice equal in capacity to that of the delivery-pipe, and an external annular orifice provided with a drairr age-channel, and an orifice for the final de' livery of dry-steam to said delivery-pipe from beneath said shield, substantially as described.

3. In a steam-separator, the combination, with a deflecting-shield surrounding the lower portion of the delivery nozzle, an exterior marginal shield-channel, and a drainage tube or tubes connecting said channel with a water-repository, of adiaphragm located beneath said shield and intersected by said tube or tubes for the delivery of condensed portions of steam to said water-repository beneath said diaphragm, as set forth.

4. A steanrseparalor having a deflecting shield, a depending delivery-nozzle, a diaphragm, and a water-trap beneath the same, the deflecting-shield being provided with drainage-tubes passing beneath the dia phragm, whereby the return of the drainage
