FRED BRAINARD COREY, OF SPRINGFIELD, MASSACHUSETTS;

STEAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 606,190, dated June 28, 1898.

Application filed April 8, 1897. Serial No. 630,634. (No model.)

particles of waterheld in suspension thereby, i and thus to deliver steam that is compara-- tively free from moisture. The same apparatus may evidently be used for removing particles of oil and other liquid or solid im- I purities from the steam.

The object of my invention is to provide a simple form of such apparatus that shall aeeomplish its purpose more thoroughly than those now in use by immediately removing the separated water and a small portion of the steam from contact with the main current of rapidly-moving steam,'and thus to guard against the possibility of the water being again picked up by'the steam and carried on into the main steam-pipe.

My invention consists in the combination, with the'main steam-passage and the waterreceiver, of a perforated wall separating the said water-receiver from the main steam-passage and a pipe or-passage leading from the upper part of the said water-receiver to the said main steam-passage and means whereby a circulation of steam is maintained through the said pipe and through the perforations of the said wall.

In the accompanying drawing, which illustrates my invention, is shown a sectional view of a separator embodying my improvements. It is tobe understood, however, that Ido not limit myself to this precise construction, as various modifications of this design might be made which would evidently come within the scope of this invention.

In the drawing, A B O D represent the main portion of the separator, which is preferably made of cast-iron in a single piece.

- This piece is flanged, as shown at A and at D,

for attachment to the main steam-pipes.

In the lower portion of the said piece A B C D the wall of the casting is perforated by the holes or slots C. These holes or slots 0 are preferably so placed that one side of each hole or slot is tangent to the curve of the inner surface at O, and thus practically tangent to the path of the steam as it is deflected around this curve in its passage from B to D.

E is a piece of pipe fitted into the casting A B G D, as shown. F is a cone that covers the top of the said pipe E, but is not in direct contact therewith. This cone F may be attached either to the'said pipe E or to the walls of the main passage A B in any suitable manner. Thin strips of metal maybe connected to the lower edge of the cone F, reaching to the pipe E and attached to the said pipe E at a point below the upper-extremity of the said pipe E, as isindicated at M in the drawing;

but I do not confine myself to this method of attachment. Thus the said cone F does not obstruct the passage of steam through the said pipe E. The water-receiver orwell G is attached to the main casting A B O D by means of the flanges H and the bolts J. This waterreceiver G is tapped at the bottom K for the attachment of the drip or waste pipe.

L represents a water-column or gage-glass for indicating the amount of water in the receiver G.

Theoperation of my invention is as follows: The steam, carrying with it particles of water,

' enters the separator at A and turns downward through the vertical passage B. As the steam rushes from the end of this vertical passage B the said steam is deflected by the curvature of the perforated wall at O, and thus because of its greater specific gravity the particles of water are thrown downward and outward against the said perforated wall 0. The dry steam passes upward and out of the separator at D, Because of the velocity of the steam and particles of water at C a portion of the separated water would be driven through the perforations at 0 into the receiver G; butat the same time the rapidly moving steam would have a tendeneyto carry the water forward and finally to pick it'up again. In order to insure the delivery of dry steam, it is therefore essential that the separated water, together with the layer of steam in contact therewith, be immediately removed from contact with the main current of steam. This I accomplish in the following manner: As the steam in the passage B passes the cone F the rations G', as desired, thus effectually elimi-- mating the moisture from the steam.

Having described the operations of and the results secured by my invention, I declare that what I claim is- 1. In'a steam-separator, the combination of a main steam-passage, a water-receiver, a perforated wall between the said main steampassage and the said receiver and an auxiliary steam-passage extending from the upper part of the said receiver to the said main steampassage, substantially as described.

2. Ina steam-separator, the combination of a main steam-passage, a water-receiver,a perforated wall between the said main steampassage and the said receiver, an auxiliary steam passage or pipe extending from the upper partof the said receiver to the said main steam-passage and a hollow cone overlapping the end of the said auxiliary steam passage or pipe but not in contact therewith, as set forth.

3. In a steam-separator, an inlet-pipe, a deflecting-plate in close proximity to the end of the said inlet-pipe and perforations in the said deflecting-plate, the said perforations being tangent to the inner surface of the said deflecting-plate, substantially as set forth.

4. In a steam-separator, a steam-circulating device consisting of a steam pipe or passage and a hollow cone overlapping the outlet of the said pipe or passage but not in contact therewith, the said pipe or passage being in communication with the water-receiverof the separator, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 1st day of April, A. D. 1897.

FRED BRAINARD COREY.
