STEAM-SEPARAT OR.

Application led January 21, 1915.

To all whom t may concern:

Be it known that I, WILLIAM S. ELLIOTT, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Steam-Separators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a vertical section of one form of steam separator embodying my invention;

Figs. 2 and 3 are sections taken, respectively, on the lines TI-II and III-HT of Fig. l;

Fig. 4 is a view similar to Fig. l, but showing a modification; and

Fig. 5 is a section on the line V-V of Fig. 4. f

My invention has relation to steam separators of the receiver type, and is designed to provide a receiver of simple and durable construction and which is well adapted to stand the severe vibrations to which its parts are subjected when mounted upon an engine or the like.

The nature of my invention will be best understood by reference to the accompanying drawings, in which I have shown two different embodiments thereof, which will now be described, it being premised, however, that various changes can be made in the construction and arrangement of the parts, without departing from the spirit and scope of my invention as defined in the ap pended claims.

Referring first to the horizontal type of separator shown in Figs. 1 to 3, the numeral 2 designates the receiver, which is shown as consisting of a large metal drum having heads 3, secured thereto in any suitable manner. In the drawings, the heads are shown as welded within the end portions of the shell and this construction is preferable. The shell of the receiver is formed near its upper' end with diametrically opposite openings, through which is extended the steam pipe l. This pipe extends continuously across the drum, one end portion projecting at one side of the drum to form an inlet connection at 5, and the other end portion extending beyond the opposite side of the drum to form an outlet connection at 6. The connections areV preferably formed with coupling flanges 6. At this inlet end Specification of Letters Patent.

` portion, it is cut away to form an opening 7,

through which the steam enters the receiver. At its outlet end, it is out away within the receiver to form an opening 8, through which the steam renters the pipe from the receiver. 8, a baflle plate 9 is secured in the pipe to prevent direct flow of steam therethrough. 10 designates oblique battles or guards which prevent any creeping of the moisture carried by the steam around the pipe il from the opening 7 to the opening 8, and also serve to deflect the steam. ll is a gage for indicating the amount of water in the receiver and l2 is a tap-off opening.

Between the two openings 7 andH The steam entering the inlet end of them' where it reenter-s the pipe through the opening 8. This gives a very effective separating action.

Figs. il and 5 show my invention applied to a vertical type of separator, the construction being in all substantial respects the" same as that just described, except that the steam pipe passes vertically through the receiver instead of transversely. Tn these ligures, parts corresponding to similar parts in Figs. l, 2 and 3 are given corresponding reference numerals with the letter a added thereto.

Receivers of this type when installed in steam lines, are subject to vibration and expansion and contraction of the line in which they are connected. They are also frequently called upon to sustain the weight of heavy pipes connected thereto, and in other cases the receiving chamber is supported on the pipe line direct. The bending moments have a tendency to distort the form ofthe separator, as well as loosen the nozzles attached thereto from the receiving chamber.

In my improved construction, the steam pipe is carried continuously through the receiver, and itself carries and supports the receiver. As the pipe is continuous, there is no strain whatever due to vibration, bending moment, etc., where this pipe makes its connection with the receiving chamber, and the tendency to open up the joints is thereby practically eliminatedi I prefer to make the area of the inlet opening 7, or 7a, materially larger than the outlet opening S, or 8a. This is clearly shown in Fig. 1. By so doing I cause the steam entering the chamber 2, or 2a, to have a much greater relative velocity than in leaving said chamber. This greatly increases the etectiveness of the separator. It will also be noted that the baffles 10, or 10a, in addition to preventing moisture from creeping around the pipe, also serve to divide the steam into two separate lines of flow. Thus the steam is delivered from the opening 7, or 7, between these two battles, and divides, part of it turning and flowing back outside of one balile to the outlet opening, and another part outside of the other baiiie. This also increases the eliiciency of the separator.

I claim:

l. A steam separator of the receiver type, comprising a receiver, a continuous steam pipe extending through the opposite walls of the receiver and connected thereto, connecting means on the ends of the steam pipe, the arrangement being such that the receiver is supported by the pipe, said pipe being provided with inlet and outlet openings communicating with the receiver, the said openings being at opposite sides of the pipe, and the said pipe having` a partition wall therein between the inlet and outlet openings, said pipe and receiver members being formed separately and the receiver member being secured to said pipe member, substantially as described.

2. A steam separator of the receiver type, comprising a receiver, a continuous steam pipe extending through the opposite walls of the receiver and connected thereto, connecting means on the ends of said pipe, the arrangement being such that the structure is ward the inlet opening, substantially as described.

3. A steam separator of the receiver type, comprising a receiver built up of a cylindrr cal shell and sheet metal heads secured to the ends of said shell, a continuous steam pipe extending through the opposite walls of the receiver, said walls of the receiver being welded to the body of the pipe, connecting means on the ends of the pipe for securing it in position in a steam line, said pipe being provided with inlet and outlet openings communicating with the receiver, the said openings in opposite sides of the pipe, a partition wall within the pipe between inlet and outlet openings, and battles secured to the pipe wit in the receiver, said bailies extending away from the outlet opening toward the inlet opening, substantially as described..

In testimony whereof, I have hereunto set my hand.
