SPECIFICATION forming part of Letters Patent No.

Application filed August 5, 1895 To @ZZ whom t may concern:

Beit known that I, ALBERT HOBERECHT, a citizen of the United States, residing at Ensenada, Mexico, have invented certain new and useful Improvements in Vapor or Steam Condensers, of which the following` specification contains a full, clear, and exact description, reference being had to the accompanying drawings, forming part thereof, in which- Figure 'l is a central vertical section of the apparatus. Fig. 2 is a horizontal section on line 2 2, Fig. l. Fig. 3 is a plan of the filtering or separating attachment.

The invention relates to apparatus for condensing steam or vap or from various sources.

The objects of the invention are to provide a simple and efficient condenser in which the steam or vapor will be subjected to incoming jet-s of cold air to condense it, the heated air passing up through a suitable stack, and in so doing causing the indraft of the colder air; also to baiiie or deflect the steam in its passage through the condenser and subject it at its various turns to the action of the cold-air jets.

The invention will first be described, and then specifically pointed out in the claims.

A is the condenser formed of an outer casing which is cylindrical in the present instance, but which may be of any desired shape and size and be supported on a suitable support. The top of the condenser is conical and from its apex. rises the stack A', while the bottom A2 tapers slightly downward to the fluidoutlet A3, as shown in Fig. l.

The casing is provided with any desired number of horizontal bathe-plates A4 spaced at their edges from the inner walls of the casing to permit the steam or vapor to pass, said plates bein g secured to the casing by any suitable form of' stays or braces d and the steam or vapor being admitted from pipe A into the condenser beneath its lowermost baffle-plate, so that it will ascend. in a serpentine or zigzag course.

B represents a series of horizontal annular cold-airehambers within the casing on the inner wall thereof and overhanging each of the baille-plates AA1 to still further baffle and deflect the course of steam or vapor, as indicated by the arrows in Fig. l. The inner inclined walls B of these annular chambers B 556,674, dated March 17, 1896.

Serial Nox 558,257. (No model.)

are each provided with small apertures l), formed by punching the metal from within the chambers outwardly through said walls after the manner of forming graters. These chambers B are connected at their outer Walls to a series of vertical cold-air-supply pipes B2, arranged concentrically to the casing by means of the short horizontal pipes or elbows B3. The lower ends of the pipes B2 extend down near the floor, so as to receive the coolest air at their lower open ends.

Every other series of horizontal pipes or elbows Bs has a damper b3 in each individual pipe, so that the cold air may be shut off from one or more of the chambers B, if found desirable. Every other pipe B2 is also provided with a damper b2. The conical top of the casing is provided withaseries of conical baffle-plates A5 to still further retard the progress of the steam or vapor and cause thorough condensation. The upper and lower of these conical bafiies are imperforate and spaced at their edges from the inner wall of the top, while the middle bafie closely fits the said top and has an aperture in its apex. The stack A will be carried up to the proper height to insure an updraft, and it has an ordinary damper a'.

C is the separator or purifier, consisting in an ordinary tanl; placed at a lower level than the bottom of' the condenser and having a central transverse filter C dividing the receiving-chamber C2 from outlet-chamber C3. The filter is in the form of an oblong reticulated or foraminated basket filled with any suitable filtering material c and held removably in vertical guideways c en the inside of the tank, so that it may be removed for refilling and cleaning.

D is a pipe having a globe-valve d and extending from the outlet A3 in the bottom of the condenser A to the receptacle c2 in the receiving-chamber, into which it discharges. The receptacle c2 is of less height than the receiving-chamber, and the liquid of condensation flows over the upper edge thereof into chamber C2 and percolates through the filter C' into the chamber C3. The pure filtered liquid in chamber C3 may be drawn therefrom in any suitable manner, but where the condenser is part of a steam-plant a pipe c3, having a globe-valve c4, will connect with IOO a pump and be carried back to the boiler` free from oil and other impurities. The water may thus be used over and over again, being purified every time and thus preventing incrustation of the boiler.

The condenser will bc found useful in many places, such as steam-plants, distilleries, &c., and may be used with or without the purifier C.

The operation is as follows: Steam is admitted at A6 and flows upwardly past the baffle-plates, causing an upward current which sucks in cold air through the apertures in the annular chambers. The air issues in jets, which impinge upon the steam. ,or vapor just as it passes upwardly around the several annular air-chambers, which is the most effective point. After passing the uppermost annular chamber the heated air must pass the upper baffle-plates, A5, which are the coolest and complete the process of condensation. The amount of cold air to be admitted may be regulated by the dampers in the air-inlet pipes and their lateral branches B3. The liquid of condensation will iow from the several ba'liie-plates and annular chambers down to the bottom of the casing to the outlet.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A steam or vapor condenser comprising a casing having an offtake or stack at its upper end and a steam or vapor inlet at its lower end, air-inlets discharging through the sides of the casing and provided with cold-air-supply pipes open at their lower ends, and horizontal baffle -plates within the casing and spaced therefrom to direct the ascending steam and vapor past the cold-air jets, substantially as set forth.

2. A steam or vapor condenser comprising a casing into which the steam or vapor is discharged and having a hot-air offtake or stack, and an annular foraminated chamber discharging within the casing into the ascending steam or vapor and having a supply-pipe; the induction of cold air being produced by the ascending heated current to the offtakc or stack, substantially as set forth.

3. A steam or vapor condenser 'comprising the casing horizontal annular series of coldair inlets or jets one above the other, discharging into the casing and provided with an external cold-air supply, bathe-plates within the casing to direct the ascending steam or vapor past said inlets or jets, and a hot-air offtake or stack to cause an updraft and the inflow of cold air through said inlets or jets. substantially as set forth.

4:. A steam or vapor condenser comprising the casing into which the steam or vapor Ls discharged and having series of horizontal annular cold-air chambers on its inner wall, the inner walls of said chambers having discharge-apertures, baffle-plates overlapped by said chambers, a series of vertical supplypipes connecting said chambers exterior to the casing and open at their lower ends for the admission of air, and an offtake or stack at the upper end of the casing, substantially as and for the purpose set forth.

5. A steam or vapor condenser, comprising the casing having a steam-inlet at its lower end and a hot-air offtake at its upper end, a series of air-chambers having outlets discharging into the casing, a series of vertical air-supply pipes exterior to the casing and each having branch pipes connected tothe said air-chambers, and dampers in certain or' the vertical and branch pipes substantially as set forth.

G. A steam or vapor condensing apparatus comprising a casing having anl offtakc or stack, an inlet therebelow for the steam` a series of cold-air inlets between the offtake or stack and the steam-outlet, and through which the cold air is drawn and discharged into the steam or vapor by the heated current ascending to the offtake or stack, a series o1' depending air-supply pipes open at their lower ends and connected at their upper ends to said air-inlets, and a purifier or separator into which the fluid of condensation is discharged from the bottom of the condenser substantially as set forth.
