v @Hommu 'or uncondensable vapors from within the condenser shell and to deliver 'the same into i chamber 0 The shaft S is rotated atsu'itable speed; the steam to be condensed enters' the condenser at K and is condensed therein and collects inthe hot well F, from which it it to the ejector E in removing the air' or iin-- coudeusable vapors is diminished and would occasion an undesired rise'in pressure within' the condenser shell. This disadvantage is overcome, however, from the fact that as the condensate diminishes, the loat e1 descends, and through the system of links dey scribed opens or further opens the valve t,

removed by the impeller Il, which deliversit athigher pressure, as atmospheric, into the discharge casing or volute V1, A

'The ejector E withdraws air or uncondciisable vapors from the condenser shell A and delivers itthrougli the pipe j and valve m into the chamber 0, and thence through the tubular projection pinto the impeller I2, which by centrifugal action further raises the 4pressure of the air or uncondensable vapors and the motive fluid from eJector E and throws it outwardly into the con- ,densate in the spaces between the vanes ful in the impeller Il, where the condeiisable vapors and motive Huid from the ejector E are condensed by coming into contact with the condensate; and air and uncondensable vapors then move with the condensate.

through the impcller Il, which increases -their pressure, and the mixture of water and air or uncondensable vapors is delivered into the discharge casing V1 at atmosphericV pressure or higher, or .at any other suitable 4 pressure.

only condensed steam, there is, relative to a `jet condenser of the saine capacity, a smaller amount of water to be removed, since in a ,jet condenser not only the condensate -but also the condensing water with which the condensate is mixed must 'he removed. The condensate is removed, as described, by the inipeller I1; but in case the amount of steam to be'conde'nsed and entering at K be diminished, as in case; of light load upon the engine or other device exhausting into the condenser A, the amount of condensate `might be so much diminished that the eX- tcnt of submergence of the impeller I, that is, the distance from the condensate level b2V to the iinpeller, is so reduced that the pump removes a less amountl of condensate; andwith less amount of water flowing through the'impeller I1, the assistance rendered by to allow or increase iniiow of water from any suitable source through the pipe s in'to u the chamber 1, from'which it passes through the aforementioned passages g1 and is delivered into the inipeller I1 into the passages between its vanes ful, thus affordingadditional water supply and maintaining the amount of water passing through the impeller I at or above the amount necessary to produce full assistance to the ejector E.

While I have herein more particularly described a surface condenser, it will be understood that my invention is not limited thereto, except where so expressed in the. claims,

lbut that 'my improved apparatus is applicable also to other types of condenser, for example, jet condensers.

It will be understood that for either or both of the ejectors E and E1 may be em.- plo'yed anyl other suitable type of ejector;

lor in lieu of themv or either of them may be used 'other means for removing gas and uncondeusable vapor from the condenser.
