Specification of Letters Patent.

Patented Nov. 3, 1914.

Application filed June 25, 1909. Serial No. 504,297.

To all whom/it may concern:

Be it known that I, OLIVER S. SLEEPER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New" York, have invented a new and useful Improvement in Jet-Condensers, of which the following is a specification.

The object of this invention is to provide a jet condenser of improved construction which isvery efficient in operation and has ing the condensing chamber, a conical lower portion B and a dome-shaped top C.

The lower end of the conical portion B of the body has a central outlet 1) which is connected with the upper end of a vertical drain pipe which is thirty-five or more feet in height and terminates at its lower end in a hot well or may be provided with other This well as usual is provided with an overflow at a point that will not allow water to rise higher than thirty-five feet in said drain pipe. On one side of its outlet 1) and above the same, the lower portion of the body is provided with a'vapor inlet 6 which connects by a conduit of any suitable construction with the source from which the vapors or steam to be condensed are dgtwn.

On one side of the-dome-shaped top of the body is arranged an exhaust or outlet nipplejc which is connected with a vacuum pump or other device whereby a vacuum is produced in the body of the condenser and the vapors are drawn from the lower inlet nipple b upwardly through the body towardthe outlet nipple.

D- represents a pipe which supplies water under pressure and which extends transversely through the central portion of the body of the condenser and Y is provided axially within the same with an upwardly turned conical jet nozzle (1 from which the water issues upwardly into the chamber in the form ofa et. As the water issues from the jet nozzle. the same strikes against the concave underside of a deflector or baffle E which Is arranged centrally in the chamber above the nozzle. This baflle is concaved or dished on its underside and provided centrally with a downwardly tapering stem point e which is arranged centrally with reference to the jet nozzle and adjacent thereto and also with a plurality of V- shaped ribs or ridges e which radiate equidlstant from the central point on the underslde of the bafile E toward the periphery thereof. This construction of the baffle .causes the water issuing from .the jet nozzle to be divided and spread uniformly and also deflected laterally and ownward against the inner side of the condensing chamber in the form of an umbrella-shaped spray which is of substantially uniform thickness in all of its parts.

The lower ends of the ribsc on the underside of the baflle E terminate below the lower edge of the bafile and also at a dis- "tance from the inner side of the same, whereby the water is maintained in a divided state after the same leaves the edge of the bafile,

thereby insuring the formation of a complete conical spray of water which intercepts all the vapors and produces the maximum condensing effect on the same.

The battle or deflector E is supported within the chamber by means of an adjusting device which permits of moving this baflle toward or from the nozzle as may be necessary or desirable to regulate the flow and distribution of the water. .The adjusting device for this purpose shown in the drawings comprises an upright adjusting rod F arranged centrally within the condensing chamber and carrying the bafile E at its lower end. Immediately above the baffle the adjusting rod is guided in a cross piece, spider or bridge 7 witlnn'the dome of the condenser chamber. The upper part of the adjusting rod passes through a stuffing box 9 in the top or dome of the chamber and is provided above the stuifing box with a threaded portion h which works in a threaded opening formed in an arch H secured to the top of the dome. Upon applying a wrench to the flat sided upper end of the adjusting rod and turning the same in one direction or the other, this rod will be raised or lowered and the bafiie E moved from or toward th,e nozzle accordingly.

After adjustment, the baifle E is held in position by a jam nut z applied to the threaded portion of the adjusting rod and hearing against the arch.

Upon being deflected outwardly by the bafiie E, the water strikes the inner side of the condenser chamber and is then intercepted by an annular balfle or flange J arranged on the bore of the condensing chamber below the jet nozzle, whereby the spray is deflected inwardly or toward the center of the condensing chamber and then passes downwardly through the reduced central passage formed in the chamber by this annular flange or bafiie J.

As the spray passes inwardly and downwardly around the inner edge of the flangeshaped bafl'le J, it strikes against the top of a circular or disk-shaped battle K which is arranged centrally within the condensing chamber below the flange baifle J and supported by means of arms Z projecting outwardly from this disk baflie and secured by bolts on to lugs n on the adjacent part of the condensing chamber or casing. The upper side of the baffle K slopes downwardly from its center toward its edge at a moderate an is and is provided with a plurality of ra ial ribs or ridges 0. These ribs gradually increase in height from their inner ends toward their outer ends, thereby causing the Water falling on the same to be divided gradually but definitely so as to insure a uniform division thereof and promote its condensing effect on the vapors. Between its ribs this bafiie plate or disk is provided -with a plurality of openings 0 leading downwardly through the same. As the water strikes the top of the baflie disk K part of the same passes through the openings thereof in the form of a spray and-part of it is deflected laterally and downwardly toward the inner side or bore of the chamber 7 in the form of an annular spray. The ribs on the battle disk K cause the water striking the same to be divided into imiform parts and directed partly into the openings thereof and partly toward the side of the condensing chamber, thereby efl'ecting an equal distrlbution of the water spray over the entire area of the condensing chamber.

As the water leaves the margin of the baflie disk K and passes downwardly along the adjacent inner side or bore of the condensing chamber, the same strikes a second.

annular flange-shaped bafiie P which is ar ran ed in the bore of the condensing chamber between the disk baflle K and the vapor inlet 6 This last mentioned baflie again turns the spray of water inwardly and downwardly toward the center of the condensing chamber and directs the same to ward the central outlet 6 at the lower end of v the condensing chamber which connects with the upper end of the drain pipe.

The vapors entering the condensing chamher through the inletnipple b are first intercepted bythe spray of water descending from the inner edge of the lower annular baflie P and through the perforations of the lower bafile disk K, whereby part of the vapors are condensed. The remaining portions of the vapor under I, the action of the vacuum pump are drawn upwardly through the condensing chamber and pass successively through the spray of water formed around the edge of the disk baffle K and the perforations therein, thence through the inwardly moving spray formed by the upper bafiie flange J and are then intercepted by the outwardly moving spray formed by the upper disk balfle E. A portion of the vapors are condensed at each step upon successively engaging the several lower sprays of water and the final portion of the condensable vapors are condensed when the same engage with the spray formed by the uppermost baflie E. The vapors which are condensed by the successive sprays are carried away to the drain with the water while the uncondensable vapors are drawn ofi from the top of the chamber by the vacuum pump or ex hausting device.

It will be noted. that in this condenser a plurality of annular sprays are ormed which are turned alternately in opposite directions and through which the vapors are compelled to pass successively, thereby increasing the condensing eiiect or capacity of the apparatus and etfectinga saving of water for condensation and of power or driving the vacuum pump.

I claim as my invention:

In a device of the character described, the combination of a chamber, and a bafiie arranged centrally within said chamber and comprising an upwardly tapering conical body and provided on its downwardly sloping upper side with a plurality of radial ribs each of which terminates at its outer end flush with the peripher thereof, and

said body being also provide with a plural- OLIVER S. SLEEPER.
