CONDENSER.

Specification of Letters Patent.

Patented April 20, 1909.

To all whom it may concern:

Be it known that I, ROYAL D. ToMLmsoN, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful Condenser, of which the following is a specification.

This invention relates to condensers and specifically to a specific construction of means for withdrawing air and uncondensable gases from the body of a barometric or jet condenser by the action of the water flowing out through the tail pipe.

It has heretofore been proposed to remove the air and uncondensable gases which collect in the body of a jet or barometric condenser by means of aspirating devicesacted upon by the water flowing out from the condenser body through the tail pipe. Ordinarily the air and gases in the body of such a condenser are in an extremely attenuated or rarefied condition so that a limit is easily reached, beyond which limit it is almost impossible for any ejector arrangement to further remove the attenuated air and gases.

This invention is designed to establish a zone of high vacuum, the vacuum being maintained in said zone by the action of the water flowing out through the tail pipe, and this zone is in free communication with the interior of the body of the condenser, preferably at some point or points wherea tendency exists for the air and gases to pocket or collect.

Specifically this invention comprises a structure of condenser and tail pipe of such a character that the water flowing through the tail pipe will form the well known ocna contracta and placing the space about this 'vena, contracta in communication with the interior of the condenser body.

Referring to the drawings which accompany this specification and form apart thereof, and on which the same reference characters are used to designate the same elements wherever they may appear in each of the several views, and which illustrate embodiments of this invention,Figure 1 illustrates a jet or barometric condenser, in elevation. and partly in section, with this. invention applied thereto. Figs. 2 and 3 illustrate similar views showing modifications.

Referring to the drawings, the numeral 1 designates a condenser body provided with the steam inlet 2, the .water injection pipe 3, the overflow pipe 4, the tail pipe 5, the umbrella 6, the spray controlling valve. 7 adapted to be actuated from the exterior of the condenser body by the lever 8, and rod 9 provided with the nuts 10 and 11.

The numeral 12 designates the hot well provided with the partition 13 located between the tail pipe 5 and the overflow pi e 4, and extended upward to a point above t e outlets of each of said pipes; and the hot well is provided with a common form of overflow pipe 14, all of these parts being of .any ordinary or preferred form of construction.

The tail ipe 5 is connected with the condenser bo y by a pipe section 15 which is preferably provided. with an enlarged flange 16 at its upper end, said flange being of the same diameter as the lower flanged end 1.7 of the condenser body to which itis secured by bolts or any suitable or preferred fastenmg means. 1

Between the flanges 16 and 17 is clam ed the annular plate 18, and between said p ate and said flange 16 a space is rovided, as at 19, preferably by recessing eit er said flange 16 or plate 18, or both, Fig. 1 of the drawings showing the flange Z16 as recessed. 1

Secured in plate 18 and extending up under the umbrella are one or more open ended pipes 20 which afford a free communication between theinterior of the body of the condenser under the umbrella thronghspace 19 to the tail pi e 5. Y

Seated upon 1;- e recessed edge of the aperture in plate 18 is a bushing 21 which is preferably beveled backwardly and downwardly, its up er surface being retained flatin order that t e water flowing out ofthe condenser may be compelled to assume a decided curve, as indicated in dotted lines by Fig. 1 of the drawings thereby insuring a good sized 'vena coatrccta being formed.

- The modification shown by Fig. 2 of the drawings is in all substantial particulars the same as the preferred form disclosed by Fig. 1, with the exception that the flange 160 of the pipe section 150 is not recessed as is the flange 16 in Fig. 1, a space 210 being formed between two bottoms 211 and 212 of the condenser body 100, a pipe 213 being provided which communicates with this space 210 from the outside of the condenser, but either this pipe or a continuation thereof extends into the condenser and opens under the urnlgrella in the same manner as pipes 20 shown y Fig. 1.

In the construction shown by Fig. 2, the aperture 214 through the uppermost bottom of the condenser is provided with a perpendicular boundary, While the aperture 21 5 provided through the lowermost bottom is provided with a downwardly and inwardly flaring periphery.

The modification shown by Fig. 3 of the drawings is substantially the same in structure as the two forms of condenser already described, with the exception that the condenser body 1000 is provided at its lower end with two bottoms 1001, 1002, and that the pipe section 1500 is preferably made integral with the lowermost bottom 1002 and extends up. within the space 2100 between the two bottoms nearly to the uppermost bot-tom 1001, this space being in open connnunication with the overflow pipe 100, through which free communication is afforded be' tween the interior of the body of the condenser and the tail pipe 5. The uppermost bottom 1001 is provided with an aperture 1003 disposed immediately above the upper open end of pipe section 1500 and coaxial therewith, the periphery of said aperture being preferably beveled outwardly and downwardly, substantially as shown by Fig. 3 of the drawings.

The operation of each of the three forms of apparatus disclosed is similar. Steam or other fluid to be condensed being admitted through aperture 2, condensing water being admitted through pipe 3 and sprayed over umbrella 6 in the usual way, the steam or fluid will be condensed and the condensing water and the water of condensation will flow out through tail pipe 5 into the hot well 12, but in flowing over the bushing 21 or through the apertures 214 or 1003, the compact stream of water will be reduced in sections at the passageways and will form the well known tend cont-rancid with the space about which either the pipes 20 or pipe 213 or the overflow pipe 400 all'ord free communication. Owing to the high vacuum created by the 0671/61, contracm, the air and uncondensable gases in the condenser body will flow in a steady uninterrupted stream into said space of high vacuum, the air when it enters said space being removed by the aspirating effect of the flowing body of water.

What I claim is,

1. The combination with a condenser body, of a tail pipe leading therefrom, said condenser body being formed adjacent said tail pipe so that the water will flow therefrom at an angle to the "flow in the tail pipe whereby a contraction of the vein or time contractd is formed, and a pipe freely communicating with the interior of said condenser body and with the space about said tend ccmtmcia.

2. The, combination in a condenser, of a body provided with steam and water inlets and an umbrella and a tail pi e, said body being formed adjacent said tai pipe so that water will :iiow therefrom at an angle to the liow in the tail pipe whereby a contraction of the vein or term contracta is formed, and a pipe affording free communication between the space within the body beneath said umbrella and the space about said vane contracta.

3. The combination in a condenser, of a body provided with steam and water inlets and a tail pipe, of a pipe affording communication between the interior of said condenser body and said tail pipe for the removal of air from said condenser body, said pipe being so positioned that it is normally surrounded by the water in the condenser body.

1. The combination in a condenser, of a body provided with steam and water inlets, a tail pipe and an umbrella, of a pipe affording communication between the space within the body below said umbrella and said tail pipe for removing air from said body, said pipe being so placed that it is surrounded by the water contained in the body of the condenser.

5. The combination in a condenser, of a body provided with steam and water inlets, an umbrella and a tail pipe, said tail pipe being provided with a section having an enlarged recessed flange, and an apertured plate secured between said body and said recessed flange and provided with a pipe extended up beneath said umbrella.

6. The combination in a condenser, of a body provided with steam and water inlets, an umbrella and a tail pipe, said tail pipe being provided with a section having an enlarged recessed flange, an apertured plate secured between said body and said recessed flange and provided with a pipe extended up beneath said umbrella, and a bushing in the aperture of said plate.

7. The combination in a condenser, of a body provided with steam and water inlets, and. a tail pipe, said tail pipe being provided with a section having a flange, an apertured plate secured between said body and said flange, one of said parts, namely said flange and said plate, being recessed, and a conduit connecting said recess and said body.

8. The combination of a condenser body, water and steam inlets thereto and a tail pipe leading therefrom, the body interiorsurfaces about the tail pipe being at an angle to in- 4 In testimony whereof, I affix my signature terior surfaces of the tail pipe whereby a volin the presence of two witnesses. ume of water flowing from said body into said ROYAL D TOMLINSON tail pipe will assume a contracted vein, and means of free communication between the said body and the space about said contracted vein.
