IMPROVEMENT N SURFACE-CONDENSERS.'

The Schedule referred to in 'these Letters Patent and making part of .the same.

To all whom it may concern Be it known that I, REUBEN LIGHTHALL, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Surface-Condensers, of which the following is a full, clear, and exact description, reference being had to the ac.- companying drawing forming part of this speccation, and in which- Figure 1 represents a vertical longitudinal section of a surface-condenser, constructed in accordance with my improvement;

Figure 2, a vertical transverse section thereof, taken as indicated by the line x x in g. l;

Figure 3, a plan of the same, in part, with the top or cover removed; and

Figure 4, a view in perspective of olie of the sectional tube-frames, detached.

Similar letters of reference indicate corresponding v parts.

. My invention. consists in a sectional surface-condenser, made up of a series of separate tube-frames, which are slid or let int-o their places in the case or shell of the condenser, preferably at some little distance apart, to form intervening vacuum and steam spaces, but practicallyconstituting an elongated tube- .surface, .composed of detached structures, which largelyvfacilitate both the construction and fitting together or repair of the condenser, and by employing only short tubes, packing the latter in the tube-sheets, to provide for expansion and contraction, may be dispensed with.

' Also, the linvention embraces a novel arrangement of ltheinlet and outlet to a condenser'for the water used in effecting condensation, whereby a more perfect action or circulation is secured.

Referring .to the accompanying drawing--4 A represents the case or shell of a condenser, to which B is the inlet forthe exhaust steam, and C a .space orchamber for its collection, before passing through the tubes, in which it is condensed by the action of cold water surrounding said tubes.

Arranged within this chamber, so as to lie in front 4of the Vadvance tube-sheet, is a perforated plate or shield, D, which operates to break the shock of the exhaust steam, and thereby to protect Asaid tube; sheet from being battered and the joints disturbed; also, which serves to divide up the steam into small jets and prepare it for distribution through the tubes.

The tubesand sheets or plates I prefer to make' in part of iron and in part of zinc, in place of using copper, `to avoid that well-known injuryto the boiler, when made of iron, which takes place from the use of copper in the condenser. l

The tubular portion of the condenseris represented as made up of a. series, consisting of any suitable number, of independent sections E E E, arranged, the one in advance of the -other, preferably, with steam and vacuum spaces F F F in between them, of sutiieient capacity to allow ot' a man entering the same, as repair or other circumstances may require, but said tubular sections may be arranged closer. t

Each of these tubular sections E E E is a perfect structure of itself, and can be 'made separately from the rest of -the condenser, and be put in and removed .from its place in the latter in a short time, and, when requiring repair, can be to replace it. l v..

'lhe sections maybe slid to their places down suitably-constructed grooves a a iu the sides of the shell,

and there be corked 'or packed; but all packing'of the tubes, to provide for expansion and contraction, may be dispensed with, and the tubes b b be made fast to the tube-sheets c c, inasmuch as said tubes only being short, variation oftemperature will not materially affeet their length, and in making them fast they are more reliable.

By thus constructing the tubular portion 'of' the` condenser in section, with the tubes in their places, before itting themwithin the condenser or shell thereof, the putting together of the condenser, especially on shipboard, is greatly facilitated.

The water of condensation arising from the passage vofthe steam through the tubes b b of the tubular structures E- E E and the intervening spaces F F F, is or may be passed from the rear of the condenser by a lower outlet, d, along side-passages c c, to the' branch f, which connects with the pump.

The water to effect condensation is introduced' by an inlet, G, near the forward end of the condenser,

from above or overthe tubes, and, after circulating among or around the tubes on their outside, the same is drawn br passed ofi', also from above, by an outlet, H, near the back end of the. condenser.

This arrangement of the inlet and outlet in the upper portion ofthe condenser, at opposite ends thereof, facilitates the descent of the cold incoming water and ascent of the heated outgoing water.

To apply such arrangement to the sectional construction -of the condenser hereinbefore described, each tube-section E E E is made to communicate at ,its bottom by an opening, g, with a lower passage, h,

which establishes connection between the several sections for the water by which the condensation is ef t'ected.Y Y

What is here claimed, and. desired to be securedby Letters Patent, is-

1. A surface-condenser,I made up of independent and detachable tubular frames or structures E E E, arranged to intersect the sb'ell, the one in advance 'of the other, substantially as' specified.

l 2. The arrangement of both the inlet androutlet G and H for the water which effects condensation, ou the upper portion of the condenser, and at opposite ends thereof, substantially as specified.
