SURFACE CONDENEEE.

My present invention relates to a surface condenser and more particularly to that type of surface condenser in which provision is made for the expansion and contraction of the condenser tubes due to the variation in heat to which the apparatus is subjected. The object of my invention is the provision in a surface condenser of an expansion joint placed between the condenser shell and at least one of the tube plates or sheets and preferably connecting the same whereby the ends of the condenser. tubes may be shrunk in the tube plates and the tube plate with which the expansion joint member is associated may shift longitudinally of the tubes to provide for the expansion and contraction thereof and wherein the construction is such as to eliminate any leakage between the condensate and the circulating water thereby increasing the eficiency of the apparatus. The construction furthermore is such as to (in tirely eliminate the use of a double bonnet at the expansion joint. end of thecondenser as heretofore employed in apparatus of this t pe.

In the drawingFigure 1 is a longitudinal section illustrating the condenser provided with the improved expansion joint member. Fig. 2 is an enlarged section illustrating this construction of the joint.

Fig. 3 is a sectional view illustrating another form of the invention, and Figs. 4, 5 and 6 are also sectionalviews showing the further forms of the invention.

Referring to the drawing and particularly to Figs. 1 and 2, the condenser shell 10 may be of the usual orany desired form and as iscustomary is provided at its oppositely disposed ends with flanges 11 and12. As illustrated. at one end of the condenser there is a tube plate 13 and a bonnet or cover 14. These parts are connected to each other and to the shell at this end thereof by means of bolts 15 passing through theflan re 12 of the shell, the outer portion of the tube plate and a flange provided for this purpose in the peripheral portion of the bonnet 14. A plurality of tubes arranged in any nested relationship are indicatedat 16 and at this end of the condenser are suitably fixed in the tube plate by means shrunk therein or otherwise. N

At the other end of the condenser as illus trated in these figures, there is a movable or shittahlie tuba plate 13b The opposite ends of the tube 16 are suitably secured in this tube plate by being shrunk therein or otherwise. This tube plate is connected to a shell by an expansion joint member 18. As illustrated, this expansion joint member is annular and conforms in outline With the end of the shell of the condenser. The inner portion of the expansion joint member is connected to the outer portion of the tube plate by means of a flat ring 19 and suitable stud bolts QOor-ot-herwise. The outer portion of the expansion joint member extends and lies betweenthe flange 11 at this end of the condenser shell and a flange 21 on a Water bonnetor cover 22. These parts are connected to each other and to the shell of the condenser by means of bolts 23 passing through aligned bolt holes provided therefor in the

flanges

11 and 21 and the outer portion of the expansion joint member 18. It will be understood that the joints between the expansion joint member and the tube plate are made tight and that a similar condition exists in the joint between the outer portion vision for an interior recess 25 for there ception of the outer or of thetube plate 17. y

In the construction of the condenser as indicated in Fig. 3, the condenser shell interiorlyis provided with a rib or fiance connected to which is a bracket 26. Slidably mounted on the bracket 26 are one or more guides 2'? which are suitably connected to the tube plate28 at this end of the shell. The expansion joint member in this structure is indicated at 29. The outer portion of the expansion joint member is connected to the internal flange of the condenser shell by means of a ring 30 and bolts 81, certain peripheral portion of which bolts may also be employed to secure the bracket26 in place on the internal flange.

The inner portion of the expansion joint member 29 is connected to thetube plate 28 by means of a ring 32 and a series of bolts 83, certain of which may also be employed to secure the tube plate 28 to the guide memher or members 27.. As illustrated in this fig are at the drawing the enter edges lit? of the expansion joint member may be ribbed as indicated at 34 and 35, making it possible to more readily secure the same in position and to maintain it. in place in relationship to the internal rib andthe tubeplate.

In the construction shown in Fig. 4: the end of the condenser shell 36 is provided with a flange 37. The outer portion of the expansion oint member 38 is placed between the outer surface of this flange 37 and the inner surface of a ring 39. These parts are connected to each other and secured together by'means of a series ofsuitablebolts 10. in this construction the tube plate is indicated at 4:1. The inner portion of the expansion joint member abuts against the outerportion of this tube plate and the expansion joint member and the tube plate are secured in position between a ring a2 and the flange 48 ofa bonnet or cover 4- by means of a series of bolts 45 or otherwise. It will be understood that in this structure the water box includes the bonnet and the tube plate and that these parts are shiftable longitudinally of the tube due to the expansion and contraction thereof, and furthermore that the movable parts at the end of the condenser may be suitably supported.

Int-he construction shown in Fig. 5, the condenser shell 4:6 is provided at one end with a boss 47, and a Water box 48 with a similarboss 49. In the expansion joint member 50employed in this construction there is a centrally disposed and outwardly extending rib or loop 51. Then the outer-portions of the expansion joint member 50 bears against the :lacesof the bosses 4-7 and 49 and respectively are secured in position thereon by means of a. ring 52 and a series of bolts58, anda ring 54- and a corresponding series of bolts 55. In this structure the bonnet 48 is provided with an internal flange 56 against which the outer portion of the tube plate 57 is secured by means of aserics of bolts 5801' otherwise. In this structure like that shown in Fig. 4, the bonnet and tube plate are shiftable longitudinally of the tubes due to the expansion and contraction thereof and may be suitably supported in this movement.

In the construction shown in Fig-6, the condenser shell 59 at one-end thereof is provided with an internal bracket 60 and a. guide or guide members 61 are connected to the tube plate 62-by means of rivets as indicated or otherwise. Lyingbetween the face of the bracket 60 and the adjacentsurface orsurfaces of the guide or guide members 61 there is a roller or ball bearing 63 upon which the guides and tubeplate are shiftable .due tovthe expansion-and contraction of the tubes. In this structure the expansion joint member is indicated at 64. The outer portion thereof is secured to the condenser shell by means o-fa ring 65 and a series of bolts 66, while the inner portion thereof is connected to the tube plate (352 by means of a ring 67 and a suitable series of bolts (38.

It will be understood that the several coustructions herein shown and described are more or less merely illustrative of the inven- 'tion as other and similar constructions may be employed without departing from the spirit thereof. It will furthru'morc be understood that the expansion joint member may be made of metal or 'i'ulu'ic or :1 combination of the same or other materials which will serve the intended purpose. and that in all instances the connectitms between the expansion joint member and the parts of the. apparatus with which it is sociuicil are made tigl'it irrespective of the term in whirl) the invention may be practiced so as to prevent any leakage between the exhaust steam or cendensate and the water or other circulating medium employed in the apparatus.
