Application filed August 29, 1925. Serial No. 53,271.

'l. his invention relates to an improved arrangement oi steam condenser and engine exhausteonnections which is adapted especially tor steam turbines, but which is applicable also to engines of other types.

in both axial and radial flow type turbines, there is a tangential, movement of the exhaust which .-,ausesa nonuniform distribution of steam throughthoexhaust connections to the condeiuier. as well as eddies and counter-currmits'which interfere with the proper flow 'ot the stean'i to the con denser.

One object of the invention is'to provide for the smooth andevcnly distributed delivery of exhaust steam itron'i. turbines of either the axial or radial flow type.

'Another object of the invention is to provide for the uniform distribution of the exhaust steam.- to the condensing chamber, so as to secure the-full condensing action of all the tubes in. a surface condenser, or to all parts of the condensing chamber in a jet condensei'z' A :turther object of the invention is to se cure the above results, while at the same time the condenser ,is supported outside the vertical line ot' the engine supports, so as to void the usual expensive constructions required for proper support 01" the engine withthe condenser directly beneath it.

F or a full understanding of the invention, a detailed description of constructions eml l forming av part of this specification, and the tealures forming the invention will then be spcci tieally pointed out in the claims.

In the drawings- Figure -1 is a 'diagramnniticend elevation of a radial flow turbine and condenser embodyin the invention l? igu re 2 is a similar side elevation looking to the left in F 1;

Figure 3 is a. somewhat enlarged view similar to 1, butshowing the condenser and connections in section, and

Figure at is a view similar to Fig. 3, showing an axial flow turbine arrangement having volute only on the condenser.

Figures 5 and Gare detail axial sections showing diagrammatieally ditl' erent forms a of turbine volutes.

Referring now especially to Figs. 13, A is the turbine, B the condenser, and C the ex- .haust connections between the two.

iodying the same in preferred. forms will now )0 given in connection with the drawings- D is the turbine support, and E the condenser support, which may be of any suitableconstruction. The condenser is shown as having a cylindrical. tube iauk 10 with central air otttake 11, although the tubes and aired-take may bearranged otherwise, the usual-hotwellf12 being provided at the bottom of the condenser. The exhaust connections C include a volute portion 13 enclosing the tube bank 10 and receiving the steam tangentially. so asto distribute steam throughout the periphery of the tube bank, and this volute condenser portion is connected by exhaust pipe 1st toa. volute portion 15 surrounding the turbine rotor 16, receiving the exhaust steam theretrom and forming an elbow by which the exhaust steam connection is carried outside the turbine support I) to the condenser, so that the latter lies wholly outside the support I) and does not interfere with the con struction of any form oi: turbine support. The steam is thus delivered properlyfrom the ;turbine and to the con denser and uniformly distributed throughout the condenser without eddies and cross currents. In the construction shown also, both the turbine and con denser may be supported as desired, without the construction being complicated by the necessity of provision for the condenser being in verticalv line with the turbine support.

In 4- an axial flow turbine is shown, the condenser volute 13 being the same as shown in Figs. 143. With this axial flow turbine, however, the turbine volute is not shown, but a. circular exhaust chamber 17 surrounding the rotor 18 is shown, from which the exhaust pipe 19 extends vertically downward, gradually enlarging to the volute 13. In this construction. the exhaust pipe extends within or between the parts of the engine support in Fig. 3, orbotli radially and axially or only axially, as desired in accordancewith the condenser arrangement or other circumstances under which it is used. For illustratiomthere' turbine rotor 18, and in Fig. 6 a turbine exhaust' passageor olute 21 expanding only axially. It will be-understood, also, that while it is important that the condenser should be "carriedoutside' the vertical line of the engine support, so to avoid interference therewith,andthislfeature forms a partof the inv bank, a volute steam chamber extending I vention, the broader features of the;inventi on relating to conveying the exhaust steam from. the engine to the condenser and the distribution of the steam .to the latter, may be used with the condenser positioned and sup- L'ported in any desired manner. "Wha is l ime 1. A steamcondenser comprising a condensing chamber, a yolute chamber extending about the condensing chamber, and exhaust connections ide'liyering the steam tangentially to the condensingchamber. e 2. Aisteam' surface condenser comprisinga shell, a tub e'bank, a Voliite chamber extending about the tube bank, and exhaust connections delivering thesteam tangentially to the tube bank. f 1 w i A steam condenser comprising acondensinging chamber, asteam inlet passage tangential to the condensing chamber extend- 'ingsubstaiitially around the chamber and of uniformly decreasing cross-sectional area.

. 4. A steam surface condenser having a circular tube bank with an air oif-take extending into the tube bank, and a steam inlet passage'.,tangentia1 to thetube bank extending -substantially around the tube bank andof bank, a volute" steam chamber extending aroundsaid tube bank,and 'an air. oft-take extending into the tubebank' at the smaller terminal of the yolute.

8. In a steam condenser, a shell, a tube around said tubelbank'and an exhaust connec: tion connnunicating with the larger terminal of said olute whereby exhaust steam passing into the condenser will enter the tube bank tangentially thereof. I

9. In a steam condenser,la shell, a' tube bank circular in cross section, a volu'te steam chamber extending around said tube bank and an'exhaust connection communicating with the larger .end of said volute whereby 1 exhaust steam will enterthe tube bank tan gentially of its perimeter.

10. In a steam condenser, ashell, a circular .tube bank, a hot well, a steam inlet passage tangential to the tube bank extending substantially around the tube bank and of uniflforinlydecreaslng cross-sectional area from its steam entrance, said steam inlet passage extending between the -:tube.bank and hot well whereby condensate during its passageto the hot well will travel through the incoming steam.

In testimony whereof, I have hereunto set my hand.
