.ings, forming part of this specification, in

Figure 1 is a vertical section partly broken away of a barometric condenser embodying my invention; and Fl," 2 is a similar view of a portion of the condenser showing :1 modified construction My invention has relation to the class of barometric condensers, and is designed to provide a novel arrangement of the steam pipe which carries the steam to be condensed into the condenser.

Heretofore it has been the practice to bring the steam. pipe into the condensing chamber through the side wall of thesame: This practice has necessitated the use of at least two large elbows in the steam pipe I? sulting in increased friction on the steam and also increasing the expense of construction, these steam pipes being often of large diameters.

According to my invention, I extend the steam pipe vertically into the condensing chamber, its upper end terminating within said chamber preferably at a point below the water inlet and provided with means of suitable character for preventing dis charge of the water into thepipe. This not only effects a saving of at least one elbow in the steam ipe, but it also enables the steam pipe to e used as a support for the condenser when desired The precise nature of my invention will be best understood by reference to the accompanying drawings, in which. I have shown twodiifcrent embodiments thereof, it being premised, however, that various other modifications may be made therein by those skilled in the art without departing from the spirit and scope of my invention as defined by the ap ended claims.

Referrin first to tie construction shown in Fig. 1, tie numeral 2 designates the condensing chamber having an inlet opening at 3 for connection with the usual water-sh ply pipe and an opening 4 at its upper on for the exhaust or vacuum pipe. 5 and 6 designate interior cones and caps, or

battles. arranged to produce a spraying action of the water discharged into the chamber at the opening 3. Any suitable ployed. In the arrangement as shown the water entering at the opening 3 flows over the upper end of the upper conch; thence downwardly into the cup below the top opening in said cone and over the edges of the cup into the lower cup 6 over the edges of which it is discharged. 7 designates the steam inlet pipe, which forms a vertical cohunn. upon which the condenser is supported, and which extends upwardly into the lower portion of the condensing chamber, terminating in a slotted or erforatcd head 8 through which the steam is discharged, this head being closed at its upper arrangement of these battles may be emend to prevent the direct discharge of.water liicrcin. 9 designates the tail pipe connected with the lower portion of the chamber 2, and which discharges into the well 10 at its lower end in the usual manner, or which may be provided with the free steam exhaust arrm'igcment described and claimed in my Patent No. 887,63 dated May 12, 1908. One or more of these tail pipes may be employed, as may be desired.

In the modification shown in Fig. 2, the head 11 of the steam pipe is of somewhat difl'ei'ont form, being referably a part of the casting 12 which orms the lower section of the inclosing'wall of the condensing chamber It will be seen that the steam will be discharged from the openings in the 11 per ends of the steam inlet pipes into the fa water discharged from the cups or baflles, so that a cmnpletc condensation of the steam will take place.

It will be obvious that the form of the discharge head of the steam pipe may be changed in various ways; and that an suitable arrangement of means for re racing the water spray may be employe 1 claim 1. A barometric condenser having a suction pipe connected with the upper portion of its condensing chamber, a steam inlet pipe extendin vertically upward through the bottom we 1 of the condenser and terminating within said chamber, and means for discharging water into said chamber intermediate o the upper end of the steam pipe and of the 'point of connection of the suction pipe, the suction pipe acting to create a counter current of steam upwardly through the discharged water; substantially as described.

2. A barometric condenser having a suction pipe connected with the upper portion of its condensing chamber, a steam inlet pipe extending vertically u wardly through the bottom wall of the cbn enser and terminating within said chamber, means for dis chargm water into said chamber intermediate o the upper end of the steam pipe and of the point of connection of the suction pipe, the suction pipe acting to create a of steam upwardly through of the condensing chamber to one side of the steam pipe and adapted to contain a barometric column of water; substantially as described.

3. i barometric condenser having a suction pipe connected'with the upper portion of its condensing chamber, a steam inlet pipe extending vertically upward through the bottom wall of the condenser and terminating within said chamber, means for discharging water into said chamber intermediate of the upper end of the steam pipe and of the point of connection of the suction pipe, the suction pipe acting to create a counter-current of steam upwardly through the discharged water, and said pipe having means at its upper end for preventing the discharge of water thereinto; substantially as described.

4. A barometric condenser having a steam inlet pipe extending vertically upwards into the condensing chamber and terminatin with a laterally perforated or slotted hea and a tail pipe connected to the lower portion of the condensing chamber to one side of the steam pipe; substantially as described.

In testimony whereof, I have hereunto set my hand.
