My invention relates toa turbine and condenser construction, and it has for'itsobject to balance the atmospheric pressures on the turbine and on the condenser, so that the condenser may be supported independently of. 4 the turbine and connected to theturbine casing by a flexible joint permitting independent expansion and contraction Withtemperature changes.

The low pressure turbine 11 is disposed over a pit 16 formed in the foundation 14, and a portion of the casing projects down into the pit. The casing is formedwith support f ing feet 17, shown in Fig. 3,.wh1ch rest on the foundation 14;

They are shown as mounted on piers 27 resting on the floor of the pit. The, C011? densers are rigidly connected to each other by a plurality of I-beam struts 28, which are disposed. in parallel vertical planes, and the 7 areas of said planes defined by the flexible bolted at their ends to, the respective condensers, as shownin Fig. .3, .the struts extend through openings 29 in the foundation;

' filed Sept. 18, 1930. Circulating water is supplied through a tunnel 30 in the foundation..

In operation, pressure within the ex-,

haust chamber and in the condensing spaces of the condensers is considerably below at.- mospheric pressure, so that the atmospheric pressure on each condenser on the, side op-' posite the inlet is eflective to bias the same are imposed against each other, and eflects are neutralized.

From the above description, it will be seen that I have provided a construction wherein the'atmospheric pressure on a condenser flexibly connectedto an exhaust chamber is counter-balanced by atmospheric pressure in the opposite directionactingon a pressureneutralizing member and transmitted through struts to the condenser. In the present embodiment, each condenser is a pressure-neutralizing member for the other condenser. Y

While I have shown my invention in but one form, 'it will be obvious to those skilled in the art that'it is not so limited, but is susceptible of various changes and modifications, without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are. specifically set forth in the appended claims.

What I claim is: Y
