"Be it known that we, ANDREW A. KRAMER and CHARLES CHAPMAN, citizens of the United States, residing at Kansas City and respectively, in the county of Jackson and tate of Missouri, have invented certain new and useful Improvements in Condensers; and we'do declare the followin to be a full, clear, and exact descriptiono vention,

the invention, such as will enable others skilled in the art to which it appertain's to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to surface condensers in which a casing or chamber is provided for the admission of steam, there being means incor' orated for passing 'coolin fluid over the wa ls of the casin or cham er so that the steam or vapor Wlll be condensed into liquid.

The invention is particularly adapted for ace condenser and one which maybe readi 1y repaired. r p

The particularly novel features of the invention will be referred to hereinafter, referencebeing had to the accompanying draw-' inwhich-- 1 is a perspective view of a condens'er constructed in accordance with our inarts being broken away to show the interior construction thereof. ,Fig. 2 is a vertical, cross sectional view through the complete condenser. i

Fig. 3 is an enlarged sectional view of one of the horizontal partition su ports.

Fig. 4 is a like view of a di erent form of an port. v

i 5 is a fragmentary, sectional view of the ischarge end of the condensate-receiv ini portion .of the condenser, and f 1g. dis a fragmentary, sectional view through a slightly modified form' of con-.

densate chamber and condensing water-receiving trough.

The condenser is shown as consisting of two triangular end plates 1 and 2,'whi ch extend substantially the height ofthe condenser with their apexes at the top The end end p ates 1 and 2 is a curved plate 5, which is'bent in the center in substantially the form ofa U, the end edges-of the plate 5being flanged, as at 6 and 7 and the flanges being fastened to the inner faces of the end plates 1 and 2 by bolts 8 and 9 respectively.

The side walls 10'and 11 of the bent late 5 converge to conform to the angles 0 the edges of the plates 1 and 2 and their ends are in-bent to form supporting flanges .12

and 13. v

Above the edges of the plate 5 are two converging plates 14 and15, which extend to the top of the condenser, where their upper ends meet, as at 16, so that they can be welded together. The upper and lower plates are welded together as at 12 in any well known manner so that a tight joint will be made at their meeting edges. The plates 14 and 15 are provided with flanges 17 and 18, which are also bolted to the end plates land 2 by the bolts, 8 and 9. The bottom ends or edges of the plates 14 and- 15 are 13'. 'Each bottom end consists of a laterally turned in and rest upon the flanges 12 and disposed portion 19, bent back uponitself in the form of a hook to provide a parallel portion. 20, as best seen in Fig. 3, the portion 20 being spaced from the portion 19 to provide a groove to receive the hooked over or inturned longitudinal edge 21 of abaflie or partition 22, Which'is the intermediate baflle or partition in the condensing chamber 23 enclosed by the bentplate 5 and the two complementary aligning plates 14 and 15. The intermediate partition terminates short of the end plate 1 and it is provided with a. depending flange 24 so that it can be grasped when the plate 1 is removed, and slid on its support 19 to remove it in the event that access to the interior' of the condenser is desired. 5

A similar plate 22' is provided for the lower baflie or partition and it engages in a groove between thelateral flange 19 arid the bent-over flange 20' on a bracket vplate v25, welded to the inside of each plate 14 and 15. The lower bafile or partition plate strip guided between the pairs 27 and 28 of angle guides.

The end plate 1 is provided witlian inlet orifice or port 29, by means of which steam or vapor may enter the condensate chamber 30. It may pass the length of the'condenser, past the short end of the bafil'e returning the length of the condenser, then over the short end of the baflle 22 for the full length of the condenser, andthen over the bafile 26, where practically all of the condensible contents of the vapor will be condensed, the non-.condensible gases passing out through the discharge orifice 27. The condensed vapor will gravitate to the condensate chamber 30. p p v The condensation takes place because the entire side walls of the condenser are subjected to cooling water which may be introduced into the trough 28, running the entire length of the condenser and having the inclined deflectors 29 and 30to direct the flow to the bottom of the trough or hopper, the edges of which are formed with serrations 31 so that slight orifices are provided, throughwhich the water may stream over the outside surfaces of the walls of the condenser and thereby maintain the walls cool enough to cause condensation of the vapor entering through the port or orifice 29.

The cooling water will be caught in longitudinal troughs 32 and 33, having openings 34 and 35 by means of which the water may be led to a sump to be re-delivered to the trough 28 or whereby the water may'pass off 'to a drain,if desired.

The-bottom of the chamber 23 andpar t-icularly the bottom of the condensate chamher or portion. 30'which really is a subjacent chamber divided from the condensing chamber 23 by the partition 22, has a discharge port 36, normally closed but which maybe opened if-desired to draw off the contents of the chamber 30. The chamber 30 also discharges into a gooseneck or pipe 37, which can be-turned about'the axis of the coupling 38 to cause it to become efiective as a drain at any predetermined level in the chamber 30. For example, if the gooseneck is in a vertical position, the level of the liquid in the chamber 30 will be higher than if it is in a horizontal position.

In order to allow the level of the liquid to rise above the inlet opening 29, the pipe leading to the inlet opening 29 should be,

vertical or substantially so for a portion of its length. Then if the steam passes condensed liquid into vapor or at least part of the liquid into vapor so. that it may be recondensed, thereby in effect causing a redistillation, making the water purer although it is not necessary to re-distill it becauseif the gooseneck is twisted or turned on the connection 38 so that the level of the liquid 39 will be below the top of the orifice 29, the steam may enter the condenser by passing over the liquid to pass through the tortuous passages formed by the baflles so that a [single condensation will take place.

In Fig. 6 we have shown aslightly moditied form of condenser base in which the plate '5 ceirresponding to theplate 5 is bent intermediate its ends and flared outwardly to form a trough 33. In the preferred form, the troughs are welded to thesides of the plate 5, whereas in the modification shown in Fig. 6, the troughs are formed integral with the plates, and supplemental plates corresponding toplates Hand 15are welded at 40.

By reference'to the drawings it will be observed that the troughs are arranged above the bottom of the condenser audit is intended that these troughs will ordinarily be above the normal level of the condensate within the chamber 33. The purpose of this is to allow the condensate 39 to be reconverted into'vapor by the incoming steam. If the cooling water surrounded the lower portion of the casing or the condensate chamber 30, the temperature would be reduced too much to permit a reconversion into vapor but. inactual practice the condensate may remain at a vtemperature somewhere.

around 200 "F., or a little above that so that the steam may carry along with it a considerableportion of the previously condensed steam to be reconverted into liquid, thereby permitting the same liquid to be re distilled.

as many times as desired.

If it is desired to have access to the interior of the condenser, the end plate 1 ma be removed and the battles slid longitudinally so that they can be taken out, then the operator may readily enter the condenser for inspection or repairs.

Of course, itis to be understood that a supply pipe or pipes may be provided over the top of the. trough or hopper-shaped receiver for theliquid so that the liquid may be uniformly distributed over the surfaces of the side members of the condenser to provide a uniform temperature throughout.
