Application filedl March 20, 1920. Serial No. 367,448.

To all 'whom it may concern.'

.Be it known that I, JoHN F. GRACE, a citizen of the United States, residing at Kearny, county of Hudson, and State of New Jersey, have invented Certain neiv and useful Improvements in Condensers, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to improvements in jet condensers, and especially to parallel flow condensers, the object of theinvention being to provide an improved construction by vvhichv a more eiiicient action shall be secured, and which shall be simple, cheap, and convenient in manufacture and use.

An especial object of the invention is the provisiony of an improved and efficient device for cooling and reducing the volume of the air having a very large cooling surface in a simple, cheap and compact construction.

For a full understanding of the invention a detailed description of a condenser embodying all the features of the invention in their preferred form .will now be given in connection with the accompanying drawing forming a part oi. this specification, and the features forming the invention then specifically pointed out in the claims.

`In the drawings Figure 1 is a vertical central section of the condenser.

Figure 2 is a section on the line-22 of vFigure 1.

Fig. 3 is a section on line 3--3 of Fig.` 2;

Fig. 4 asection on the line 1*-4 of Fig. 2, showing a slightly modified form of the valve shown in Fig. 2; p

Figure 5 is section onthe line 5-5 of Figure 1.

Referring to the drawing, the condenser shell is preferably made in sections. as shown, A. being the hot Well section, having the usual tail pump connection 11, B the air cooling section' having outlet 12, connected to the usual dry vacul'nn pump or other eX- hausting means, and C the condensing section having steam and condensing Water inlets 13, 14,'respectively. These sections are preferably arranged as shown, so that each lower section supports those above it, and one section may be turned upon the other to bring the connections 11, 12and 14 in any desired position Without any change of patterns or effect on the other castings, thus enabling the connections to the injection, air and tail pumps to be made in any direction.

Referring now to the interior construction of the condenser, the inlet section C is provided With a conical partition 15, extending into the section B and dividing` the section C into a condensing chamber' 16 and a condensing Water supply chamber 17, connected by passages 18 to 'a plurality, of nozzle chambers 19, preferably four in number, having spray nozzles 2() suitably secured therein. n

I preferably provide an annular downwardly proiecting cooling chamber 21'Which is open at its upper end to thevvater charnber 17 and extends into the sec-tion B and surrounds the lower end of the partition 15 to form the cooling element for the air passing from section B through connection 12.

The section B is provided with tvvo annular flanges 22, 24, bearing againstsection C to form. annularpassage's 25 and 23. A portion of the flange 24: is cut aivayv on the same side of the condenserias connection 12,` to

form a port 26 yconnecting passage 25 with the interior of the condenser and flange 22 has port 27 on the opposite side of the condenser connecting the passages 25, 23. The

bottom of ,section B preferably is so formed that it partly covers lthe hot ivell section A i to prevent eddies from carrying Water into the air suction.

The operation is as follows:-

` Exhaust steam enters the condensing chamber 16 at 13, and is there met and condensed by sprayed cooling Water which is delivered from Water chamber 17 by pas sages 18, nozzle'charfibers 19 and nozzles 20. The commingled steam and Water then pass through the contracted portion of the partiH tion 15 to hot Well section A Where the air and uncondensed vapors separate and pass upward to the air cooler for increase of pressure and reduction of volume previous to Withdrawal by the evacuating means.

The air and vapors enter the cooler by port 26 and pass around to the other side of the condenser through annular' passage 25, being cooled during this movementby the inner Wall of thecooling element 21. Then the air and vapors pass through port 27 to annular passage 23 in which they are cooled by the largel outer surface oli the cooling elcment 2l as they pass to connection l2 `for withdrawal by the evacuating means.

rlfhe cooling' water may be controlled by a Avalve in tli'e inlet pipe as usual, but l prefer to use valves controlling the i'low at or near the nozzles as by such a construction the excess head of water is utilized to secure increased pressure at the-nozzles, thereby oby taining a iiner division of the water and a. more etlicient condensation of the steam.

In the construction shown, twoci' the nozzles 20, preferably opposite ones, are controlled by val-ves, one of which. will beA describe/d. The nozzle chamber 19 is provided with. anopeninrg, in the condenser shell closed by a valveV casing l which is provided with annular ports 2 registering with the passage 18. tubular valve 3 slid-ing within the casing l controls the ports 2, and is connected by spider arms et and hub 5to valve rod 6, which passes through stutling box 7 and isconnected to a suitably pivoted bell crank lever 8, actu-ated manually or otherwise by rod 9. The valve 3 is lneferably of thc` balanced' type, and so'fbahufieed that the pressure of the water will hold itin any position`r to which it has been' moved'. ln the modification of this valve as shown in Fig. LL, the valve is provided with an annular lip upon the inner endthereof against which the water acts as a positive means for hold ing the valve in its full open or closed position'. In .the intermediate position this lip has no effect as the pressures upon opposite sides thereof are balancedand the valve will thereby remain in any position toy which it moved.

A `further fea-ture of my invention consists inl thev provision of improved means for separating air from the condensing water previous to its delivery to the nozzles 20. rlhis device is of the form shown, in which a chamber 28 is provi-ded at Vone side of the water chamber 17 and separated theil'etrcnn by a wall 27 extending upward nea lhy the water level in the chamber 'I7'. .4i 29 connects the Lipper portion.l of the chamber' 28 to the annular in` section .j so that the air anni willrenmve is collected in tl e upper portion ot the chy nbers 28 and 17 by separation `trom the condensing water.

A. valve connected tofloat ill by lever 82, pivotal'ly mounted in bracket 33 secured` tothe chan-iber wall controls the inlet of the tube 29 to prevent the air pump from drawing` Water fromv 'the chamber 28' in case the water supply should become excessive. The float' 3l may be guided by suitable means, as by pin 34e within plug 35. In order to direct the incoming water upward to cause a separation .Of they air inthe upper portionot the chzunbers 17 and 28, l provide a baffle 36 which crosses the chamber 17 at a short distance from the inlet connection 14:.

By providing a separate cha-n'lber i'or the iloat and valve controlling the tube 29, I prevent the upward movement oi the water from raising the iloat and closing the valve at times when" this action is not necessary.

Itwill be understood that the invention is not to be limited to kthe construction shown and described, as many changes may be made therein while retaining the invention deiined by the claims.
