CONDENSER.

Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed October 1,1904. Serial No.226,762.

T 0 a 11/72/0772, it may concern:

Be it known that I, JOHN F. GRACE, a citizen of the United States, residing at New York city, county of Kings, and State of New York, have invented certain new and useful Improvements in Condensers, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of the present invention is to provide improved means for collecting the air and uncondensed vapors in the condensing-chamber of those classes of condensing systems in which the air and uncondensed vapors, or part of these, are removed from the condensing-chamber separately from the discharge-water, the especial object of the invention being to provide a simple and comact construction by which the amount of iquid collected with the air shall be reduced and the air cooled and condensible vapor therein condensed and removed as the air passes to the air-pump.

For a full understanding of the invention a detailed description of a construction embodying the invention as applied in its preferred form will now be given in connection with the accompanying drawings, forming a part of this specification, and the features forming the invention then specifically pointed out in the claims.

In the drawings, Figure 1 is a diagram-- matic elevation of a condenser system embodying the invention as applied to a common type of gravity-injector condenser system. Fig. 2 is a central vertical section of the condensing-chamber and air-collector. Figs. 3 and 4 are vertical and horizontal sections of the air-collector and cooler.

Referring to the drawings, A is the condensing-chamber; B, the steam-pipe entering at the top; O, the condensing-water pipe through which the condensing water is forced by the circulating-pump D E, the discharge or tail pipe of the condenser through which the discharge-water passes to the hot-well F, and G the air-pipe leading from the condensing-chamber A to the air-pump H. The condensing-water pipe O enters the lower part of the condensing-chamber A and extends upward centrally of the chamber, the water being delivered from its upper end past an adjustable spray-nozzle I, which is ribbed ver tically on its periphery and carried by avertical rod 10, movable vertically for adjustment of the nozzle I by being screw-threaded through a stufling-box in the steam-pipe elbow, as usual in such constructions.

All the parts thus far described and shown are of a form common in this class of condensers; but it will be understood that they may be of any other suitable form,

Referring now to the means for collecting and cooling the air and uncondensed vapors to which the present invention especially relates, there is mounted on top of the condensingvater pipe C, so that the condensing water passes upward through it to the spraynozzle 1, a hood or bell at, extending over a considerable part of the condensing-chamber and open at the bottom to receive the air and uncondensed vapors arising from the lower part of the condenser within the space between the falling condensing water and the condensing-water pipe O. Within this hood a and inclosing or forming a continuation of the condensing-water pipe O is a casing I), shown as formed of an inner cylinder 11, through which the condensing water passes, which cylinder is inclosed within a second cylinder or shell 12, mounted upon the top of the condensing-pipe O, these two cylinders 1 1 12 being formed to provide an air-chamber c between-them, this chamber 0 opening to the bell a in the upper part of the latter through passages 13, formed in the outer cylinder or shell 12. These passages 13 are not formed radially, but inclined to the radius and directed forward in the direction of movement of the air as it passes to the air-pipe G, so as to be approximately tangential to the airchamber, better separation of the liquid from the airbeing thus secured. To direct the air to the openings 13, the forward side of the openings 13 is protected by a lip or shoulder 1, formed on the shell 12, as shown clearly in Figs. 3 and 4. As many of these openings or lips as desired may be used, four being shown. At one side of the air-cooler the air-chamber c connects with the upper end of the air-pipe G within the condenser by passage 14,. Drainpipe 15 connects the bottom of the elbow of pipe G within the condenser with the tailpipe E, so as to carry off the water condensed from any vapor collected with the air.

For the purpose of better securing the separation of liquid from the air and condensing any vapor entering the hood or bell a with the air as well as cooling the air the inner side of the bell a is provided with vertical ribs 2,- which aid in separating the liquid from the air and which increase the amount of coolingsurface with which the air and vapor engage. The bell and ribs 2 are cooled efficiently by the condensing water sprayed over the top of the bell a, and the air within the chamber C is further cooled by its contact with the inner cylinder 12, through the inside of which passes the incoming condensing water. The top of the bell a or, as shown, a separate plate mounted thereon is preferably provided with vertical ribs 16, forming slots through which the water is sprayed out sidewise past the spray-nozzle I, so as to fall in a shower on the top of the bell a and within the space surrounding it.

It will be understood that the invention is applicable to condensers of different classes and that in condensers of the general class of that shown the condensing-water pipe and air-cooler may be otherwise arranged, this de-.

pending somewhat on the style of condenser to which the invention is applied. It will be understood also that the invention is not limited to the special manner in which the aircooler is formed or connected with the con- (lensing-water pipe, but that the detail construction of the air-collector and cooler may be varied while retaining the features covered by the claims.

What I claim is- 1. The combination with a condensingchamber, of an air collector and cooler therein consisting of a bell opening downwardly, a casing forming an air-chamber within said bell, air-passages connecting the bell with the air-chamber and inclined forwardly in the direction of movement of the air, and an airdischarge pipe connected with said air-chamber.

2. The combination with a condensingchamber, of an air collector and cooler therein consisting of a bell opening downwardly, a

casing forming an air-chamber within said bell, air-passages connecting the bell with the air-chamber and inclined forwardly in the direction of movement of the air, projections on the inner side of the bell, and an air-discharge pipe connected with said air-chamber.

3. The combination with an injector condensing-chamber and its condensing-water pipe and spraying devices, of a casing through which the condensing water passes to the spraying devices, an air-chamber within said casing having its inner side cooled by the condensing water, an air-collecting bell outside said chamber over which the water is sprayed, air-passages from said bell to said air-chamber inclined forwardly in the direction of movement ofthe air, and an air-discharge pipe connected with said air-chamber.

4. The combination with an injector condensing-chamber and its condensing-water pipe and spraying devices, of a casing through which the condensing water passes to the spraying devices, an air-chamber within said casing having its inner side cooled by the condensing water, an air-collecting bell outside said chamber over which the water is sprayed, air-passages from said bell to said air-chamber inclined forwardly in the direction of movement of the air, ribs on the inner side of witnesses.
