'2 Claims.

HOurinvention relates to surface condensers,

more particularly of the marine type, and it has for an object to provide a condenser with beam members connected thereto andwhich function, not only to support the condenser, but to cooperate with the latter to provide a supporting or bed construction for turbines and the like.

A further object of our invention is to provide a condenser having its shell welded to end plates .constituting webs of supporting beam members whose outer ends are carried by supports, the

beam members'belng attached to the supports at one side of the condenser so as to resist movement of the beam members bodily in .the direcfree to move horizontally with respect to the supports at the other side of the condenser to accommodate expansion and contraction thereof as well as of .the condenser. I

These and other objects are effected by our invention as will be apparent from the following description and claims taken in eonnection with the accompanying drawings forming a part of this application, in which:

Fig. 1 is a top plan view of a power plant incorporat-ing the improved condenser arrangement; Fig. 2 is a side elevation of the apparatus shown in Fig. l with a portion of the casing structure broken away to show the gearing and the cou- Dling;

ratus shown in Fig. 1;

modified arrangement;

Figs. 5, 6, and 7 are detail sectional views taken Fig. 2; and,

lines VI1'IV1II and IX-IX of Fig. 4.

Referring to the drawingsmore in detail, there is shown a condenser having a shell III enclosing a nest of tubes ll connected to tube plates l2. The shell I is welded to end plates 13 to which the tube plates I 2 are connected by stud bolts M, the latter also preferably holdin'gthe water boxes IS in place with respect thereto. The 'end plates l3 constitute widened intermediate portions [6 of the webs l-l of the beams or girders, at 18, the beams or girders being constituted by the webs and by suitable strengthening and stiffening flanges l9.

As shown, the beams or girders l8 have their supports 20 formed on the casing 2| of the reduction gearing, at 22. The ends of the beams carried by supports 23 formed by any suitable tions of their length and the beam members being Figj3 is an end elevational view of the appa- Fig. 4 is a view similar to Fig. 2 but showing a alongthe lines V-V, VI'-VI and VII-VII of Figs. 8 and 9 are detail views taken along the coplanar with or parallel to the webs ll.

other ends of the beams it! in Fig, 4 may be slidends, at one sideof the condenser, carried by or girders, at theother side of the condenser are venient means for supporting apparatus, for ex-v example, the high-pressure turbine-25 andthe low-pressure .turbine 26.. Preferably, a cross beam 21 is arranged between the beams l8 and connected thereto. The condenser shell l0 car-v ries a supporting structure 28 spaced from'and arranged substantially parallel to the cross beam 21.

. The high-pressure turbine is supported at the end adjacent to'the' gearing by means of a pedestal}! carried by the cross beam 21 and at-the other end by means of aflexible I-beam section 30 mounted on the structure 28, the I-beam section having-its web arranged transversely of the turbine and being, therefore, capable of flexing -to accommodate-for axial expansion and contrac- .tion of the high-pressure turbine.

turbine and flexing to provide for expansion and contraction, the exhaust end of the low-pressure being free to slide endwise and laterally on the I supports 23. 'In this embodiment, therefore, t he beams l8 are capable of expanding and contracting lengthwise with respect to the supports 20 and they have sufllcient inherent flexibility axially of the condenser to accommodate for expansion and contraction of the condenser shell.

In the second form of our invention, the neces-' sity for the small amount of flexing onthe part of the beams I8 to accommodate expansion and contraction of the condenser is avoided or very largely reduced by means of the I-beam sections 36 fastened to the supports 20 and having adjacent ends of the beams l8 secured thereto, the

I-beam sections 36 having their webs arranged The hold the turbines in predetermined relation with.

Accordingly, in the embodiment shown in respect to the reduction gearing, other provisions shouldexist torestrict the condenser and beam aggregate from shifting laterally at the end remote from the reduction gearing and disturbing the relation of the turbines and the gearing as well as the relation of the condenser to its auxiliaries. Accordingly, we provide plates 40 attached at one end to the ship's structure at 4].

'ed by couplings capable of accommodating misalinement. 'For example, in Fig. 2, we show the spindles 32 and 33 having their adjacent endsv provided with peripheral teeth 42 and 43 encompassed by a muff member 44 having internal teeth meshing with the teeth 42 and 43, the muifmember being of adequate length-to take care of any misalinement.

While we have shown our invention in several forms, 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 we desire, thereiore, 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 we claim is:

1. In a power plant condenser arrangement,

. supports arranged to provide a space therebetween; a pair of spaced beam members providing a supporting bed construction, spanning said space, and having their outer ends carried by said supports; and a condenser including a shell located in said space and end plates for the shell formed by webs of the beam members.

2. In a power plant condenser arrangement, supports arranged to provide a space therebetween; a pair of spaced beam members providing a supporting bed construction, spanning said space, and having their outer ends carried by members, a nest of tubes within the shell. tube plates for the tubes, water boxes, means for securingthe tube plates and thewater boxes to the end plates formed by the beam member webs,

means for; supporting the outer ends of the beam members at one side of the condenser so as to re- 1 sist bodily movement thereof lengthwise, and means for supporting theouter ends of the beam members at the other'side of the condenser so as to provide for movement thereof horizontally in any direction.

4. The combination with a power plant condenser, of means for supporting the condenser including a pair of. beam members, said beam members having intermediate and depending widened portions joined to the ends of the condenser, means for supporting the outer ends of the beam members at one side of the condenser so as to resist movement thereof bodily in the direction of theirlength, and means for supporting the outer ends of the beam members at the other side of the condenser so as to provide formovement thereof to accommodate for expansion and contraction of the condenserand for contraction and expansion of the beam members in the direction of their length.

5. The combination with a power plant condenser, of meansior supporting the condenser including a pair ofbeam members having intermediate and depending widened portions joined to the ends of the condenser, first supports for the ends of the beam members at one side of the condenser, second supports for the ends of the beam members at the other side of the condenser, and means for attaching the first supports to the corresponding ends of the beam members to resist movements thereof bodily in the direction of their length, said second supports and the corresponding ends of the beam members being constructed and arranged to provide for movement of the beam members so as to accommodate expansion and contraction of the condenser and of the beam members in the direction of their length. I
