STEAMQ-SEPARATO R.

SPECIFICATION forming part of Letters Patent No. 624,575,-dated May 9, 1899. Application filed September 17,1896. Serial No. 606,130. (No model.)

To Ml whom it may concern;

Be it known that 1, JOHN EDSON SWEET, a citizen of the United States of America, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Steam- Separators; and I do hereby declare the following to be a full, clear, and exact description of the in ven tion,such as will enable others skilled in the art to which it appertains to make and use the same.

Reference is made to the accompanying drawings, forming a part of this specification, in which--.

Figure 1 is a cross-section of my improvement. Fig. 2 is a side elevation of a portion of the same in place in a marine boiler such as is in use in the United States Navy. Fig. 3 shows in longitudinal section a modified form which can be used in an extension from the boiler in cases where it is not desirable or practicable to introduce the separator into the boiler itself, and Fig. iis a cross-sectional View of the same.

Like letters of reference refer to like parts upon the drawings.

The details of the several parts will be described below.

My invention relates to improvements in steam-separators for marine boilers; and it consists in a modification of my invention in separators patented January 8, 1895, No. 532,296, whereby it is especially adapted to the purpose above mentioned.

In marine boilers itis quite common to have a simple form of separator, known as a drypipe, extending along the top of the boiler, in the steam-space thereof, with perforations in the top of the pipe intended to take the steam from the driest part of the space where it is least impregnated with free moisture. Experience, however, shows that under the motion of avessel at sea the water in the boiler can by no such means be kept out of the drypipe, but under the rollin g action of the waves is often thrown to the top of the boiler and deflected upon the dry-pipe and enters the perforations with the steam. My invention is designed to supply a remedy for this defect and furnish aseparator which may be introduced and used within the boiler or an extension thereof with the same facility as the dry-pipe and yet be free from the aforesaid disadvantages. i

In my former patent, No. 532,296,I have shown and described a separator locatedin a vertical exit-pipe from the boiler or anenlargement thereof, consisting, in brief, of a frusto-conical shellof perforated sheet metal 7 panying moisture behind and emerge in a comparatively dry state. My present device is constructed on similar principles, but horizontally disposed and arranged, so as to be readily introduced through a manhole into a marine boiler or an extension thereof in the position and with the functions heretofore pertaining to the dry-pipe. The perforations on the top of the dry-pipe are dispensed with, and a provision is made whereby the water from the swash of the boiler is more effectually prevented from entering the separator.

In the drawings, Ais a segmental pipe corresponding to the former dry-pipe, but open at the bottom.

B is a metallic trough or its equivalent under and covering the opening in A, extending upward along the sides of'the pipe A, with a narrow passage 0 between and firmly and detachably secured to the latter by spacing bolts f, nuts h, and sleeves i, as shown, or in any other suitable and workmanlike manner. The upper edges of the said trough are furnished with outturned lips I), and a corresponding outturned lip a is supplied above each, leaving a narrow slit or passage-Way 0 between the two, extending lengthwise of the separator, of a dimension of opening corresponding to the size of the outlet. This slit is the entrance-passage for the steam and may obviously be employed on one or both sides of the pipe with similar results. The

purpose of the outturned lips is to deflect and ward off from entrance any water which may be splashed up or deflected down upon. the separator.

WVithin the trough B is secured a perforated sheet-metal lining or sieve D, passing downward along the sides thereof, as shown, and turned sharply upward at the loweredge in a curved deflection g just below the edge of the open pipe A The two edges meet and are joined in the center, as at (Z, and, if desired, a partition-plate e is secured in place at this point to arrest the water from'either side and prevent its going through the perforations on the other side. E E are the outlet-pipes, which drain the accumulating water from the separator into the boiler. They terminate below the waterline thereof, and theirlower terminals are protected by suitable check-valves. (Not shown as their function is well known.)

M is a section of a portion of the shell of'a marine boiler.

'12 n are the hangers for securing the separator-pipe.

The operation is as follows: Steam enters freely through the inlet slits or passages G, whence it passes along down through the passages c, over the perforated linings or sieves D, and is deflected upward into the steamexit pipe A. In its passage the water in the steam is forcibly thrown against the said sieves and through. the perforations thereof,

where it is entrapped by its own comparative inertia and the surface attraction exerted by the extended metal surface and is thus partitioned away from the more mobile current of steam to be withdrawn through the eductpipes E E.

In the modification shown in Figs. 3 and 4 A is a horizontal "extension from the boiler, in which the pipe A is located. The lateral inlet-slits C in this modification are dispensed with, since the separator is in this case protected from the swash of the water in the boiler. The steam enters through the passage O into the space -or chamber F, surrounding the upper portion of the separatorpipe A, whence it finds its way through the narrow passages c c, as before, passing over the sieves or lining-plates D, the steam being deflected, as before, into the interior of the pipe A and thence passing out through the exitway I, while the water, being thrown forcibly against the sieves D, passes through them and is held in the chamber below and thence drawn off to be returned to the boiler, the, lower segment of the pipe A in this case constituting the trough B and serving the functions thereof. G is the usual water glass gage.

I claim and desire to secure by Letters Patent 1. A steam-separator for location within the steam-space of a boiler, consisting of a horizontal pipe having a long narrow steaminlet opening in the side or sides thereof, and outturned lips above and below said opening, whereby water is deflected away from the same, substantially as specified.

2. In a steam-separator, a horizontal pipe, open at bottom, in combination with a trough overlapping the same from the bottom to about midway of the sides, leaving downwardly-inclined steam-inlet spaces between the sides of the pipe and the overlapping trough, guarded by outturned lips, substantially as shown and. described.

3. In a steam-separator, a horizontal pipe, open at bottom, in combination with an overlapping trough, spaced to afford steam-passages, and the outturned lips a b, forming guarded steam-inlets at the sides of the separator, substantially as shown and described.

4. In a steam-separator, the combination of the horizontal pipe, open at bottom, theoverlapping trough spaced to afford passages between the same, the outturned lips a 1), forming guarded steam-inlet slits, and perforated linings or sieves secured to the said trough within the said passages, substantially as shown and described.

5. In a steam-separator, the combination of the horizontal pipe A, open at bottom, the trough B, detachably secured thereto'and affording steam-spaces c, outturned lips a, b, forming lateral guarded steam-inletsC, perforated sieve-linings D, having upturned deflections g, joined in the center, and outletpipes E, substantially as shown and described.

(5. The herein-described improvement in steam-separators, consisting of a horizontal member double walled and spaced at the, sides, provided with lateral steam-inlet slits guarded by outturned lips a Z), perforated metallic sieve-linings secured within the doublewalled spaces, having upturned deflecting lower edges, a central partition 6, and outlet-pipes E, all substantially as shown and described and for the purpose specified.

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

JOHN EDSON SWEET.
