i To all whom it may concern:

Be it known that I, RAYMOND "N. ERR-- HART, a citizen of the United States, and a residentof Edgewood, inthe county of Alle'gheny and State of Pennsylvania, have made a new and useful Invention in Bar,

ometric Condensers, of which the following isa specification.

This "invention relates to condensers and more particularly to barometric condensers. Condensers of the barometric type are ordina-rily supported by or mounted on the tail pipe, that is, the pipe through which the leaks in its joints.

mixture of condensing water and the water of condensation flows. Such an arrangement is liable to and does givetrouble in large size condensers, due to the expansion and contraction of the exhaust line or pipe through which thesteam to be condensed is delivered to the condensers. The exhaust line .or pipe up to the condenser is large and consequently rigid, and if the vacuum in the condenser drops the steam temperature in the exhaust'increases, but there will be no material increase in the temperature-of the water discharged through the tailpipe. The result is that the exhaust pipe W111 ex and and the amount of .its expansion wil be greater than that ofthe tail pipe, so that there will be a differential expansion between the two, which will either tearthe condenser loose [from its foundation, or start The object of this invention is to provide aparallel flow barometric condenser which overcomes dificulties now This and other objects, which will be made apparent throughout the further description,v

of the invention, are attained by means of a condensing tures herein described and illustrated in the single sheet drawing accompanying and forming-a part hereo In the drawings, I have illustrated in vertical section, a condenser embodying my' invention, portions being broken away for convenience'of illustration.

The condenser illustrated includes a casingfl, which is provided with a steam inlet port 3, amixture discharge port 4:, an air ofittake 5, and condensin jets 6. The jets 6 communicate with and re-- ceive condensingwater from a water chainber' 7 formed in the head casting 8 of the encountered.

apparatus embodying the tea water delivery condenser, and discharge the water downwardly through a mixing tube or cone 9, located within the condensing chamber 10 and between the jets 6 and the mixture discharge port 4. The chamber 7 is shown communieating with a pipe or passage 11, through which condensingi water from any suitable source is delivers As illustrated, the lower or dischargeend of the mixing cone 9 projects into a chamber 12, which is located within the condensing chamber 10, and around which a steam delivery passage 13, communicating with the exhaust port 3, extends. The walls of the 16 located between the lower end of the mix ing cone 9'and the wall of the chamber 12, and the rojecting end of the cone masks the inlet end of the passage 15.

he inlet port 3 of the condenseris located ,at the-. bottom' oft-he casing 2 and is preferab ly '"concentric with the cylindrical'wall of the casing. "Withthis arrangement steam .to be condensed Y entering the condenser through the port 3 travels upwardly through the annular passage 13, to the upper end of the mixing cone 9, where it is subjected to I the cooling efiect of the water discharged from'the jetsfi. In order to direct the flow of the steam into the mixing cone 9 and to avoid objectionable eddy currents, I have;

provided a directing plate 17 which, as illustrated, is in the form of a ring and is provvided on the lower side with a concave face and on the upper side with a convex face and lssecured to the top casting 8 by means of webs 18. The top casting is provided, at a point contiguous'witli the directing plate 17, with an annular directing face 19, which is concave and .face of, the plate 17 an annular'directing y thewebs 18. As illustrated,-the center of curvature of the convex face of the plate which forms with the convexv passage 21, which is divided into segments 1 His substantially coincident with the center of curvature of the concave face 19 and consequetly-the steam passage formed between these two faces has substantially parallel walls, and isso arranged that-the steam passing through it will be graduallyrreversed in the direction of its flow and is delivered into the converging cone with the condensing ivater discharged from the jets 6. The concave face of the plate 17 also operates to gradually reverse the direction of the flow of steam entering the mixing cone through the passage formed between the-plate and the upper edge of the cone and it directs the steam into the cone. With this arrangement the flow of steam and Water throughout the zone of condensation is parallel.

As illustrated, an exhaust pipe or header 522 communicates with the inlet port 3 and is provided with an elbow foot 23 on which the condenser is mounted. With this arrangement, the condenser is free to move as the exhaust pipe or header expands and contracts, since the tail pipe swings free from the mixture discharging port 4 and there is no possibility of damaging the condenser by reason of the expansion and contraction of the exhaust pipe.

While I have illustrated and described but one embodiment of my invention, it will be apparent to those skilled in the art that various modifications, substitutions, changes, additions and omissions may be made in the details of construction without departing from the spirit and scope of theinvention as set forth by the appended claims.
