CONDENSER.

Patented Aug. 10, 1915.

Application filed July 23, 1913. Serial No. 780,683.

To all whom it may concern:

Be it known that 1, JOHN F. ME'r'rEN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State-of Pennsylvania, have invented certain new and useful Improvements in Condensers, of which the following is a full, clear, and exact specification.

This invention relates to devices for condensing steam and the like. I

The main obje-t of the invention is to provide a condenser in which the expansion and. contraction ofthe cooling'tubes may be permitted and, at the same time, the flow of steam will be broken up, by preventing the flowing of large volumes of steam in straight lines through thecondenser.

Other and ancillary objects ofthe invention will appear hereinafter.

' In the accompanying drawings which illustrate the invention Figure I is a vertical transverse section or the condenser, partly broken away; Fig. 2 is a horizontal section on a reduced scale on theline 2, 2 of Fig. 1 looking in the direction of the arrow; Fig. 3 is a portion of a vertical transverse section showing the manner. ;ot rt'ing the tubes; Fig. 4 is an endview of; structure shown in Fig. 3 lookingfronr-the right; and Fig. 5 is a detail plan view'showing the manner of securing the tube supporting strips from longitudinal movement.

"the end caps or heads 2 and 3. Secured near Referring to the drawings, the egg-shaped form of condenser shown is of the conven-" tional type used on vessels known as. torpedo boat destroyers, but it will, of course, be understood that'the invention is not limshown a casing comprising the straight sided portion 1 to the ends of which are secured the ends of the casing are the tubesheets 4 and 5 which form water-tight partitions so that the casing is divided. into a. middle chamber inclosed by the portion'l o'f the casing and the tube sheets A and 5 and two end chambers between the heads '2 and 3,

"and the tube sheets 4 and 5 these end chambers being fluid-tight from the middle chamber. Between the tube sheets 4L and 5 are supported tubes which open into the chambers within the heads 2 and 3, and extend through the central chamber. The tubes are arranged in layers, for instance, there are the tubes 6 of one layer-and the tubes"! of tion.

' another layer. It will be observed that in which comprises the tubes 7, the tubes are curved laterally in the opposite direction, and this method of arrangement, namely, having the tubes of alternate layers curved in opposite directions, is carried out in the difi'erent layers of tubes in the condenser. As will beseen, the holes in the tubesheets in which the ends of the tubes are'inserted are staggered; that is, the tube holes of successive layers are not in vertical alinement.

To support the tubes truss bars or beams 8 are supported upon brackets 9 secured to the casing, these beams being distributed verticallyin suflicient numbers and spacing to support the weight of the tubes, the numher and spacing of. such beams being obviously dependent upon the design of the conof the condenser, according to the length of the tubes. Between each laye'r'of tubes are placed strips 10 which serve to separate the layers and support the tubes in proper posi- These strips are distributed longitudinally of the condenser, their number de pending upon the length of the tubes, as will be well understood. The strips 10 are prevented from longitudinal displacement by meansof channel bars 11 which are secured to the sides of the casing and within which the ends of. the strips enter. At the top of the condenser, in the design shown in the drawings, the strips are secured at one end by channel bars as 12, which may also serve as braces, while at the other ends of these strips" is a curved channel bar 13. Bafile plates as14 may be secured in any suitable ,m'anner so as to project from the sides of the casing, retard the flow of fluid, and direct it to the center.

The steam to be condensed is passed into the condenser through an intake 15 which may be reinforced by a brace 16, which is shown in Fig. 1 as a vertical plate in which are apertures 16. The steam willithen pass downwardly transverse to the layers of tubes, and will .be condensed asfiir passes down and around the cooling tubes. The condensed steam settles to the bottomof the casing from which it may be drawn by any suitable provision, as will be understood.

' It will be observed that as the steam protween the tubes,

gresses through the condenser, it finds no straight path for large bodies of steam bebut that the cooling tubes cross each other and are again and again interposed in the path of the steam so that this path'is-broken up and the condensation of the steampromoted.

It will be further observed that by the difference in direction of curvature of the v tubes of different layers, the condenser sides 1 may be straight,- whereas if the tubes cases,

curved in the same direction in all layers, if the sides of the caslng were not made curved to follow the curvature of the tubes, there would be \vaste' spaces at the middle on one side and at the ends on the other. It is, therefore, with the present constructionentirely practicableto use condenser casings having straight sides, and at the same time. use the curved tubes which permit of ex pansion and contraction.

' The fluid passed through the cooling tubes.

tubes and this might be effected by introducing water into one end head, passing it through the tubes and withdrawing it from the other end head. Any well known man ner of supplying and withdrawing the water I 1 may be employed, as will be well understood.

While I have described the invention in what is considered its best application, it is to be understood that it may be embodied in other structures without departing from its however, a circulation of water will" be kept up through the end heads and the spirit, and is not, therefore, limited to the structure shown in the drawings. 4

Having thus described my invention, I declare that what I claim as new and desire to secure by Letters Patent is: 1. In a surface condenser, the combination with a casing having tube sheets spaced from each end to form an intermediate condensing chamber,of corresponding rows of horizontal holes in each tube sheet, the holes in one row being inclined oppositely to those of adjacent rows,

: tube sheet being inclined toward the holes of corresponding rows in the other tube sheet, and curved tubesfitted in said respective rows of holes in said tube sheets so that the tubes of onerow cross those of. the

adjacent rows to break up the steam 'flow from straight lines.

2. In a surface condenser, the combination with a casing having tube sheets spaced from 'each end to form an intermediate condensing chamber, of correspondingrows of horizontal holes in each. tube sheet, the holes in one row being staggered and inclined oppositely tothose of adj acent rows, said rows of holes in one tube sheet being inclined toward the holes of corresponding rows in the other tube sheet, the number of holes in each rowdeoreasing from the top to the bottom of said tube sheets, and curved tubes fitted in said respective rows of holes in said tube sheets so that the tubes of one row cross those of adjacent rows to divert the steam flow from straight lines while concentrating it toward the bottom.

In testimony whereof I aflix my signature, in presence of two witnesses. JOHN F. METTEN.
