densate in the body of the heater in the-dis charge thereof flows over the tops of these longitudinal walls through the passage defined by these walls and the transverse walls to the heater discharge opening 21.

At one end of the body of the hot well heater there is a flange 22 and this is fittdd with a tube plate 23' and a bonnet 24, these parts being connected by bolts or otherwise as is customary. In the bonnet 24 there isa flanged nozzle 25 by which communication is made through a pipe 26 and the opening 14 in the condenser shell to that portion of the interior of the condenser adjacent the exhaust steam inlet thereof. At the opposite end of the hot well heater shell there is a flange 27 similar to the flange 22 and at this end of the shell of the hot well heater there is also a tube plate 28 and a bonnet 29, these parts being secured together by bolts or otherwise as is customary, and the space within the bonnet 29 and between the same and the tube plate 28 is connected to the interior ofthe condenser shell 10 by a pipe 30 or otherwise. Extending between the tube plates 23 and 28 and suitably connected at their ends there is a plurality of tubes 31, these tubes extending through the entire body of the hot well heater as will be understood and being completely submerged by the condensate which passes from the condenser to the hot well heater.

A pipe bent in the form of a U to form a trap is connected at one end to the wall 33 forming the lower end of the discharge portion of the hot well heater and at the other end in the bonnet 29 so as to make communication between the lower end of the discharge of the hot well heater and the space between the bonnet 29 and the tube plate 28 so that any steam that may condense will drain back into the discharge of the hotwell. The discharge opening in the hot well is connected by a pipe 34 to the hot well pump as is customary.

In the use of this apparatus, the exhaust steam is conveyed to the space within the condenser shell and is condensed by coming into contact with the tubes therein through which circulating water is continuously passed to maintain the temperature thereof sufficiently low to condense the steam, while the condensed steam or condensate passes to the bottom of the condenser and through the discharge opening 12 into the interior of the hot well heater, at the same time a portion of the exhaust steam as conveyed to the condenser passes through the opening 14 and through the pipe 26 so as to fill the tubes J 3i extending through the body of the hot wel heater in order that the heat from this exhaust steam may be transferred through the tubcs'to the condensate in the hot well heater in which the tubes are submerged. It will be understood, of course, that any part of this exhaust steam which may condense in the tubes in the hot well heater will drain to the space between the bonnet 29 and the tube plate 28 and will be trapped to the discharge of the heater, while provision is made for the passage of exhaust steam unutilized in the hot well heater through the pipe 30 to the interior of the shell 10 of the main condenser, it bein also understoml that in use condensate fills the body of the hot well'heater inasmuch as in leaving the same it must overflow the longitudinal walls 20 to reach the discharge passage and the outlet from the hot well heater.

I claim as my invention:

1. In a condenser apparatus and in combination. a condenser, a hot well associated therewith, a plurality of tubes extending through the body of the hot well, devices in the hot well discharge for maintaining the condensate in the hot well at such a level as to submerge the tubes, and means for directing steam into the tubes in the hot well.

2. In a condenser apparatus and in combination. a condenser, a hot well connected to the said condenser, a plurality of tubes passing through the body of the hot well, interior walls in the body of the hot well forming a discharge passage therein over which walls the condensate is caused to flow in leaving the hot well so that the said tubes are submerged in the condensate, and means for directing exhaust steam from the condenser to the tubes in the hot well.

3. In a condenser apparatus and in coilibination, a condenser, a hot well connected to the said condenser, a plurality of tubes extending through the body of the hot well transverse walls in the body of the hot well, longitudinal walls also in the body of the hot well and acting in conjunction with the transverse walls to form a discharge outlet passage from the hot well, the condensate flowing over the said longitudinal walls through the discharge passage so that the tubes in the hot well are submerged, and means for directing exhaust steam from the condenser to the said tubes in the hot well.

4-. In a condenser apparatus and in combination, a condenser, a hot well connected to the said condenser and comprising an open ended body member, tube plates and bonnets connected to the ends of the said body member, a plurality of tubes extending between and connected in the said tube plates, a connection between the said condenser and one end of the hot well body for conveying exhaust steam from the con denser to the tubes in the hot well, and means within the body of the hot well for maintaining suflicient condensate therein to submerge the said tubes in the operation of the apparatus.

5. n a condenser apparatus and in combination, a condenser, a hot well connected Leer-Bette tn the said condenser and comprising an open ended body member, tube plates and bonnets connected to the ends ofthe said body member, a pluralitx of tubes extending be tween and connected in the said tube plates, a connection between the said condenser and one end of the hot Well bodyfer conveying exhaust steam from the condenser to the tubes in the hot Well, opposltely disposed l0 transverse Walls in the body of the hot Well,

and spaced longitudinal Watts also within the body of the hot wet]. ceepemting with the said transverse wells to form at discharge passage for the condensate over which said longitudinal walls the condensate flews t0 the discharge passage se that the said tubes are submerged in the cendensete in the taper ation of the rppuratns.
