Another object is the production of a con denser construction in which suitable pro- .vision is made by which the expansion and contraction of the condenser parts resulting from the varying temperatures to which the condenser is subjected may take place without injury to the condenser.

The various features of novelty which characterize the invention are pointed out with particularityin the claims annexed to and fonnin'g' a part of this specification. For a better nderstanding of the inven tion, howe'v ,agid the advantages possessed by 1t, reference may be had to the accompanying drawings and descriptive matter in avhich l have illustrated and described one of the forms in which be embodied v Of the drawings; Figure 1 is a plan, and Fig. 2 is a sectional elevation taken on the line 52-42 of Fig. 1.

In the drawings I have shown the condenser as employed in conjunction with a steam turbine A. The exhaust chamber .5. of the steam turbine being connected by the lateral. pipe section A? to the base member from which rises the vertical steam pipe B of the condenserpropeix The bottom of the base the invention may member 13 is slidingly supported .on' the horizontal slide rails Qwlnch, as shown,

C rests upon the cover C" of the hot well C, the cover being supported on the transverse beams The condensing chamber is formed by a drum D which is supported by the exhaust pipe- B. The upper end of the pipe B projects some distance into the drum D, which is of materially larger diameter than Specification of Letters Patent. pgfientgfl A 0 27 191% Serial No. 667,085.

pipe B,'thus forming a reservoir or space D into which the hot water collects and from which leads the main tail or waste pipe F. Between the upper and lower ends of the drum D is connected the cold water supply pipe E and the outlet'G for the exhaust or vacuum pump. Connection G leads from the side of the drum D adjacent its upper end. The drum D is provided with the usual water reservoirs Dvand D and ballles or water spreaders D and D and with a scparatormember or battle D The member I) is in the form of a hollow truncated cone secured at its base to the member 1) below the outlet to the connection G and projecting in front of said connection, and as shown having its open upper end D extending above the outlet G Provision is made, as by ports D for allowing watercollecting in the space D to pass ownward into the reservoir D.

The pipe G which runs from the connection G to a pump or other pressure exhauster not'shown, leads from the connection G above the lower end of a tubular member G which serves to prevent Water which may be carried in to the connection G from passing into the pipe G. The connection G has an air inlet port G controlled by the value H, which is normally'held in position to close the port G by the spring acting on the external cap H connected to the outer end of the valve stem H The lower end of the connection G is open to the hot well through the tail pipe I. The lower ends of the hot well tail pipes F and I extend into casings I and F respectively, havingfflap outlet valves I and F and normally resting on the seat C provided at the bottom of the hot well.

In normal operation, water enters the condenser chamber D through the conduit E, and passing downward eventually flows to the hot well through the tail pipe F the steam entering the condenser chamber D from the engine through conduitB being condensed by this water. Any considerable flow of water out of the condenser D into the connection G which may occur from time to time results at once in the accumulation of sufficient water in the leaky receptacle H to pull open the valve H against the action of the spring normally holding it closed, thus admitting air to the condenser chamber to break the vacuum therein and are arranged at one side-of the pipe B and restore the normal downward flow of the the tail pipe F at theother side, so that the water in the condenser. When the normal weight of each of-these connections tends counter current action of the condenser is to counterbalance that of the other.
