SPECIFICATION forming part of Letters Patent No. 673,984, dated May 14, 1901.

Application filed September 6, 1899. Serial No. 729,650. (No model.)

To ctZZ whom, it wttty concern:

Be it known that I, ALBERT HOBERECHT, a citizen of the United States, residing at Ensenada, in the Republic of Mexico, have invented a new and useful Improvement in a Combined Steam Condenser and Aerator, of which the following is a specification.

Myinvention relates to condensers in which the air is used to cool and condense the steam into water; and the object thereof is to provide means to condense the steam into water by mingling the air freely therewith, so that the water resulting therefrom may be used again for steam purposes, or it may be used for domestic purposes, having been thoroughly aerated. I accomplish this object by means of the mechanism shown in the accompanying drawings, in which- Figure 1 is a central vertical section of my condenser, the stack removed, the deflectors G and H being shown in elevation. Fig. 2 is a cross-section taken on line 1 2 of Fig. 1. Fig. 3 is a vertical central section of the stack A, partly cut away, showing the damper S in its open position.

A is the outer shell or casing, cylindrical in form, at the top of which is the cone-shaped extension A, upon the apex of which is mounted the stack A. Concentrically arranged within the outer shell are a number 'of inner casings B, C, D, and E. These casings are open at the top and bottom to permit the passage therethrough of steam and air. The top of these three first-named inner shells are contracted, as shown at B, C, and D, for the purpose of imparting to the steam passing therethrough an accelerated motion, and consequently producing a suction on the outside of the shells B and C at their upper or discharge ends. At the bottom of the shells B and C are arranged annular V-shaped troughs J and J, upon which these shells rest. These troughs communicate with and discharge their contents into the radial troughs N,Which in turn discharge into the annular trough P, running around and outside of the bottom of the shell B and. within the outer shell A. Leading from this trough P is the dischargepipe L. Connecting with this pipe are branches M and M, leading from the lower troughs P and P. These latter troughs are formed, respectively, by attaching the bottom flange E of the shell E to the wall D of the shell D and by attaching the shell F to the wall D. Above the trough Jand surrounding the shells D and C and affixed thereto are deflectors Iand I. Above the bottom flange E and surrounding the shell D" are a series of cone-shaped deflectors K. Below these deflectors are a series of holes K for the passage therethrough of air. Below the flange E and between the shells F and D is an annular steam-chamber Q, into which the exhaust O discharges. Suspended within the shells A and D, respectively, by suitable brackets are the hollow inverted-cone-shaped deflectors G and .11, having aprons G and H, respectively, the purpose of which is to prevent the condensed water from running along down the cone-shaped deflectors to the apices thereof and dropping down the central opening.

The steam entering the steam-chamber Q through the exhaust 0 will circulate around in the chamber and be discharged therefrom through the passage Q, over the top of the shell E into the shell E, drawing with it the air in the shell F. The passageway is contracted that the movement of the steam pass ing therethrough may be accelerated and create a suction, thereby to draw the air in the shell E into the passing steam. It will be observed that at the openings 2 and 3 the same conditions exist as are found at 1' and for like purposes. The mingled steam and air will pass thence into the shell E and be discharged into the shell D. As it passes up the chamber it encounters the inverted-coneshaped deflector H, around which it passes, being contracted as it passes around the projecting base of the cone, causing the steam and air to more thoroughly commingle. In passing up from the shell D into the shell D the combined steam and air will create a suction, which will draw from the chamber R the air therein, which will commingle with the steam and air. In passing through the upper end of the shell D a suction will be created at the passage 2, drawing with it theair contained in chamber T, which will commingle in shell C with the ascending steam and air therein. Passing up out of the shell C it will create a suction in the passage 3, drawing the air contained in chamber U, which will commingle with the ascending steam and air in damper S to regulate the flow of the steam and air therethrough. This damper will operateto fix the amount of air which is fed to the condenser. I do not limit'myself to the number of shells shown herein, as in summer weather or in hot climates more will be required than in winter or cold climates, it being my intention to regulate the number of shells so that all the steam will be condensed before the air passes out of the stack. The condensed water will be precipitated first into the flange E and pass out. As it passes up outof the shell D the steam will be further condensed in the shells C and B and be deposited on the deflector H. Running over the top it will drop from the apron H around and outside of the shell E. The condensation in the stack will drop upon the top of the cone G, pass over the same, and drip from the apron G outside of the discharge B of the shell B and be deposited in the trough P, whence it will pass into the pipe L. The condensation taking place in the chambers T and U will be deposited upon and around the deflectors I and I, thence down into the V- shaped troughs J and J, thence into the troughs N, thence into the trough P, and thence on and out through the pipe L.

It will be manifest that the water produced by the condensation, as above described, will be thoroughly aerated and'fit for domestic use, as well as being entirely freed from all foreign matter, which renders it objectionable for steam purposes.

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

1. Asteam condenser and aerator, comprising a casing having a stack at its upper end, openings to admit steam and air at its lower end, a plurality of inner casings being coneshaped at theirupper ends, open at the bottoms and tops thereof to admit air at the bottom and discharge the same at the top into a central passage way connecting directly with the stack; an exhaust-pipe connecting with the central passage-way, whereby steam passing therethrough will be discharged into the central passage-way and create a suction and draw the air in the telescoping casings into the central passage-way thereby condensing the steam and aerating the water condensed thereby, substantially as shown and described.
