' This invention relates to new and useful improvements in steam condensers, and more particularly it pertains to steam condensers as employed in ships and the l1ke.
generally employed for. condensing the steam of the engines of ships, great difiicultyis ex-f perienced withv contamination of the boiler water by the leakage of salt water around 1 the various joints ofthe condenser and'a consequent seepage of salt water-intothe boiler water thus l vention so to construct a steam condenser that even'though a leakage around the olnts occurs salt water cannot seep through the leaking joints to the interior of the. conj denser and contaminatethe boiler fwater.
It is a further objectofthe invention to :provide a new and novel construction of steam condenser for use in ships in which I certain joints which lead directly to theinterior of the condensing receptacle or chamsalt water upon said joints is eliminated.
reference is had to the accompanying drawings, wherein:
' Figure 1 isa detail fragmentary sectional view, of'a ship showing a condenser constructed in accordance with the present invention located therein, and the several cirr culating systems incidental to 'the'operation of a condenser constructed in accordance with the present invention, V
Figure 2- is a longitudinal sectional view partly broken away of a condenser constructed in accordance'with the present invention, and; '1 Figure 3 is an enlarged detailsectional View illustrating a construction employed in connection with the condenser.
Referring specifically to the drawings the In the construction ofsteam condensers as ber are protected against contact with salt water, and thus the damaging effects of the gether. -It is to be I h s H fluid tubes 19 extend through both of the condenser by means of a pump 12 which connects" with' the interior. of the condenser" through the plates 1 8,theregare condensing.

Preference character-10' designates the "con- ;d enser,' and steamtobe condensedisledthere- [to by means of asuitable ipe connection 11. r Water of condensation is carried from "the 7' by a suitablepipefline13.1Fronithepuinp 12 the water-is carried to thejfeed {waters-u "ply'by means jof a pipe line'such as15f Byflrefer'ence to Figure '2 it wilfl' be noted 17 that the condenserlb comprisesa condensing ireceptacle '16 theendsof which are flanged as H 17. The, ends iof'the condensing receptacle are closed by meansof plates 18; andexte'nde in'g through the"bOndenser']receptacle"and' V and these endmembers are'also flanged as indicate d at to abut the flange of theflplates "19 Bolts or. rivets passing. through these "abutt'n 'fl ngesforin the means h which the With the above. and other objects in View, 1 g a y several parts of the condenser are secured tounderstood the'condensing plates ateach end of the condenser. and that a In Figure 2, the header member-:24; atuthe left hand side of, said figure is illustrated as having apartition or wall 3O extending therethey'are secured thereinby means of ferrules,
-,nu ts orin any conventional manner.
across; and as also? illustrated in this figl'i re r the chamber formed by, this'header'memher -24is providedwith a suitable inlet pipe 31 I and-anoutlet pipe32l By reference toqFigure'l it will benoted-that theoutlet'pipe connected as at 33 with a suitable circulatf ing lpu'mp, and'that theoutlet' '32 "passes through the side of the ship and discharges i overboard.
By this construction it will be apparent that the salt water or other water is pumped in through the side of the ship, is passed by way of the inlet pipe 31 to the space below the wall to the opposite end of the condenser from whence it passes through the upper portion of the condenser to the space upon the upper side of the wall 30 and thence over board by way of the discharge pipe 32.
To prevent this circulating condensing fluid from entering the condensing chamber of the condenser, and thus polluting the Water of condensation, I circulate through the spaces between the plates 18 and 20, fresh water and this fresh water as illustrated in Figure 1, is supplied by means of a tank 35 and is circulated by means of a pump 36 through a pump 37 which branches as at 38 into tube feed lines 39 and to which communicate with their respective ends of the condenser 10 and the fresh water is, returned by means of a pipe line or the like 41. Water may be supplied to the supply tank 35, by means of a pipe which leads from the pipe 15 to a I location adjacent the supply tank 35 and is discharged thereinto as illustrated at 16 in Figure 1. I v j By reference to Figure 2 it will be noted that in the case of salt water forming the the pipe 19 and either of. the plates 20, the pressure under which the fluid is circulated between said plates will prevent the entrance of salt water through said leak. If, however, the pressure of salt water were greater than ing receptacle having flanged ends, a plate adapted for engagement with the flange at each end of the receptacle, a plate having an off-set flangeadapted forv engagement with said first mentioned plate to form a space at each end of the condensing receptacle, a header at each end of the condensing chamber, single means for securing together, all of said elements, and means for maintaining a circulation of fluid through the space between each end plate and its respective spaced plate.

In testimony whereof I afiiX my signature.

condensing fluids, should a leak occur between a the pressure of the water between the plates,
such salt water as would seep through the ruptured portion and into the space between the plates 18 and 20, would not or could not enter the condensing chamber 16 and contaminate the water of condensation therein which is to be later used in the ships boiler.
From the foregoing, therefore, it'will be apparent that the present invention provides a new and novel condenser construction which prevents the pollution of boiler water by condensating fluids becoming mixed therewith. In the present device, this is excluded by means of a wall of circulating water which is interposed between the cooling fluid and the interior of the condenser.
