CONDENSER.

Application filed February 4, 1927. Serial No. 165,863.

i 'erant and a plurality of connected internal tubes to: wateror a like cooling medium. It likewise relates to similar structures which operate reversely by evaporation in brine coo ers and the like, and which are hereinand in the subjoined claims classified c n is a main object of the'ii e mize leakage, and toprevent annnci escaping into the water used in co; of the specified class; to render the in tubes and'the outer tuies oi such con-dens mutually adjustable in compensation to their unequal longitudinal eXpan contraction caused by the thermal changes to which they are operatively subjected; to eliminate from the interior of the outer tubes all joints and pipe bends between the inner tubes or parts thereof; to effect the mutual adjustment of inner and outer tubes auto-- I use; to expedite and facilitate the discovery anc stoppage of all leakages in condensers of the specified class; to stop such leakages, it any, by operative adjustment ofparts ot the con(lensers. \vitl1 out dismantling'the' apparatus and without recourse to structural repair; to -ma l;e the inside of the inner tubesreadily accessible for cleansing and the like; and'in general to attain collectively in condensers of this class all the advantages, without the disadvantages, which pertain'to double-pipe condensers in general. I

To accomplish these results I incorporate in my improved condenser, either singly or innumbers, as parts thereof, an outer tube. shell, or casing, which has terminal heads hereinafter called ammonia heads a plurality of inner tubes which extend, without joints orpipe'bends, through the interipr of a singleouter tube and through its. heads, a pair oi out-er'hcads spaced from the ends of theouter tube, and'having water passages communicating with the inner tubes, an apertured intermediatehead slidable on the water tubes between'each' water head and the adjacent ammoniahead, a correspondingly apertured casket between each outer head and the adjacent intermediate he l. packings and a detector ring which encircle each inner tube between each ammonia head and the ad acent intermediate head, means for mutually adjusting the adjacent heads,-

and inlet and outlet water pipes which pass through sh lling-boxes in the opposite outer heads respectively.

In said drawings, which illustrate the best manner wh rein I have contemplated applying the principles of the invention. Figure 1 is a partial elevation of the right hand end of a multiplex condenser comprising a plurality of connected single, or shell and tube. condensers which are constructed in accordance with these principles. The rest of the figures are details. Fig. 2 is elevation of the inner'side of the left hand waterhead. Fig. 3 is a section on section line 3-3 of Fig. 2. Fig.- 4 is an enlarged portion of Figures 'Tand 8, including one of the detector rings. Fig. 5 is a side elevation of one of the intermediate heads.

of Fig. 5. Figures 7 and S are axial sections of a left hand'end portion of the conden ser of Fig. 1 on the section lines 33 and 77 respectively of Fig. 2. 9 is a partial en'd elevation of the right hand end of the condenser of Fig. 1.

In these drawings the outer tubesof which two are shown in Fig. 1are duplicate cylindrical steel shells, which are denoted by the numerals 1. They have ammonia inlet pipes 2 and 2' respectively. and

ammonia outlet pipes

3 and 3"respectivelv. Each of them has at each end an ammonia head l and a perforated peripheral flange 5. These heads are formed integrally with the outer tube and have for the accommodation of the inner tubes the holes 6.' wh ch are counterbored from the outside for the packings which are hereinafter described. The

inner tubes, of which the odd number seven are shown in each'ammonia tube, are a group of duplicate spaced pipes denoted by the numerals 7. They are a littlelonger than the outer tubes in which they are placed, and project adjustably through the counterbored holes 6 in the ammonia heads. The outer heads8 and 9 are a. pair of flanged iron castings facing toward each other at the opposite ends respectively of each single condenser. The head 8 contains the chambers, channels or water passages 10. 11 and 12, opening in and through its face,

1,ees,soe

and registering and intcrcommunicating with individual pairs respectively of the inner tubes 7; and also contains the water passa e 13, piercing the head in the direction of its thickness and in axial alinement with the single unpaired water tube 1 and having at the back of the head the discharge outlet 14. In the multiplex condenser shown in Fig. 1 this outlet has a vaste pipe 15 leading through the stutlingboxlG to the waste-pipe reader 17. In like manner the outer head 9 contains the

water channels

10, 11 and 12, similar to the

channels

10, 11 and 12, and a. pertorating Wilt "1 passage which is similar to the pa" n 13, and axially alined with the end of the supply pipe 15. The latter leads from the supplypip-e header 17 through a stutlingbex to this alined water tube. bus the

heads

8 and 9, without the aid of any pipe bends, complete a continuous connection of the inner tubes in s ries between the supply pipe 15 and the outlet pipe 15.

The intermediate head 18 is a circular steel plate located between each outer head and the adjacent ammonia. head. It has perforations 19 for the inner tubes 7 respectively; and these perforations are counterbored in the side of the intermediate head which is next to the ammonia head, for the packings 24:, which are hereinafter described. It has a plurality of screws, or studbolts, 20, projecting from its opposite sides. Between each intermediate head and the adjacent outer head is placed a gasket 21, which has openings corresponding respectively to those in the face of the outer-head itself.

The. detector rings are cylindrical or sleevelike, and have their opposite ends in parallel planes at rightangles with their axes. They are formed of Babbitt metal or the like and are severally adjustable by sliding on the water tubes 7 respectively between the ammonia heads and the adjacent intermediate heads. Each ring has a plurality o't vent holes 23 extending from its hollow interior to its peripheral exterior. Contiguous to the opposite ends respectively of each detector ring, and similarly encir cling the water tubes 7, are two pairs otresiliently compressible gaskets 2 t, formed of india rubber or the like and dapted to serve as packings in the

counterbored perlorations

6 and 19 of the adjacent heads i and 18.

For the purpose of manually adjusting, and of holding, the described heads in atpropriate positions relative to each other, the flanges of the outer heads and of the outer tubes are perforated by the bolt-holes 25, which are occupied by the stud bolts 20, having nuts 26.

For the purposes ot initial adjustment of the condenser, and for the stoppage of leaks, the intermediate heads are operatively approximated to the adjacent outer heads and to the adjacent ammonia heads by an attendant by turning the appropriate nuts 26; but all ordinary and slight mutual adjustments of the heads, normally requisite during the operation of the condenser, are er tected automatically by the compression and expansion of the resilient gaskets 2% caused by unequal expansions and contractions of the inner and outer tubes. If any ammonia should chance to leak past -the resilient gaskets in the ammonia heads, and if any water should leak past any of those in the intermediate heads, the same will be immediately discovered escaping through the open vent-holes 23 in the detector rings.
