Specication of Letters Patent. Patented Aug, 12, 1919;

Application led September 19, 1917. Serial N o. 192,196.

To all whom t may concern:

Be it known that I, RAYMOND N. EHR- HART, a citizen of the United States, and a resident of Edgewood Park, in the county of Allegheny and State of Pennsylvania, have made a new and useful Invention in Condenser-s, of which the following is a speciication.

This invention. /'relates to condensers and has for an object to produce a condenser which 1s more compact than other condensersof the same type now in use and ducela condenser of reduced height but of4 large capacity.

A further obj ect of my invention is to produce a condenser having a plurality of shallow combining cones which produce substantially the same results as a larger, and therefore deeper, single combining cone.

A further object is to roduce a condenser of reduced height and width for a given capacity.

The drawing is a diagrammatic sectional view of a condenser embodying my invention.

A well known and eilective form of jet condenser includes a vertical cylindrical shell having a steam inlet port at the top and a condensate well and outlet port at the bottom. Inclosed within the shell is a combining cone which forms the only means of communication between the steam inlet port and the condensate well of the condenser. Cooling water is sprayed into and through the combining cone by means of nozzles located above the cone. The steam to be condensed entersl through the inlet port, and is almost immediately subjected to and miXed with the spray of cooling water, with the result that the steam is condensed. The mixture of condensate and cooling water falls through the cone to the condensate well at the bottom of the condenser shell, and the air which leaks in or is carried into the condenser with the steam and water collects around the combining cone and between it and the shell. The air offtake port is located in the shell near its point of` connectionv with the cone. The condensate pump is frequently located within the condensate well tor compactness.- These condeni'seis'are well known to those skilled in the art and require no further description.

The condenser illustrated in the drawing is similar in principle and operation to the condenser just' described, but through the application of my invention is vmore compact and much more adaptablevfor use in places where space, especially headroom is not freel y available. As shown, the condenser is pro-A vided with a shell 5, which may be of any shape in plan View, but is preferably made rectangular for economy of space. The shell 5 terminates at the bottom in a condensate well or collecting chamber 6 which, as shown, is provided with a condensate outlet port 7 and supporting-feet 15.

Instead of employing a single combining cone as in the ordinary forms of jet condensers, I have shown this condenser as provided with a deck 16 at an intermediate point in the shell 5, from which a row or nest of combining cones 8 project downwardly into the lower part of the shell. In the illustrated embodiment of-my invention I have provided five cones arranged in a single row. These cones are preferably geometric reductions of the cones ordinarily employed and therefore, are of reduced height and diameter. The reduction in cross sectional area of the cone is compensated for by the increase in the number of cones.

A steam inlet chamber 9 is formed within the shell 5 above the deck 16 and isv provided with a lateralsteam inlet port 10. A water box 11, to which water may be delivered through a lateral inlet port 12, is provided above the inlet chamber 9.

As shown, the inlet chamber 9 tapers from a maximum height at the inlet end to a relatively small height on the opposite end, the taper being suchthat the cross sectional-area varies in accordance with the diminishing p volume of steam as the steam is distributed to the combining cones and is condensed. In order'to secure a uniform distribution of cooling water 'to the cones 8, I have shown the nozzles 13 as mounted or formed on the clined baille plate 18 is shown adjacent to this port for preventing water from splashing into the air outlet port, or from being carried in by the current of air. As this condenser is relatively long, one or moreair ports may be provided in the shell.

The operation of this condenser is similar to that ot' the condensers of ordinary construction. The same high efliciency is obtained and, if desired, the parts of the condenser illustrated in Fig. z may be similar to those ot' the well known condensers but a ot` reduced size, resulting in a condenser of similar characteristics but of reduced height. vWith the rectangular construction shown, having a single row of combining cones, the condenser is of reduced height and width, and is-therefore well adapted to be litted in a place of low head room and of small lateral dimensions. Such a condenser may be advantageously employed on boats, on locomotives, or in any location where compactness is an important consideration. In the condenser shown, all piping connections are lateral which further adds to the vertical compactness of the installation.

lVhile I have illustrated and described but one embodiment ofiny invention, it will be apparent to those skilled in the art that various changes, modifications, additions and omissions may be made in the apparatus described and illustrated without departing from the spirit and scope of the invention as set forth by the appended claims.

lVhat I claim is:

1. In a jet. condenser, a shallow condenser shell terminating at the bottom in a collecting chamber and having a steam inlet, an inlet chamber for receiving steam to be condensed, said chamber being tapered from the inlet end to the other end thereof, a plurality of combining means between the inlet chamber and the collecting chamber and means for delivering cooling water in the form of spray to the combining means, said combining means being shaped to facilitate the condensation of the steam and opening it their lower ends into the collecting cham- In a condenser, a condenser shell, a steam inlet chamber having a steam inlet port, said chamber being tapered from the inlet end to the other end thereof, a row of combining cones communicating with the inlet chamber, a plurality of nozzles for delivering cooling Water to the cones, said nozzles being mounted on extensions depending through the inlet chamber so as to be at a substantially uniform distance above the conesand means for delivering cooling Water to the extensions and nozzles.

In a condenser, a' condenser shell having a steam inlet, a water box closin the condenser, having its under side inc ined downward away from the inlet so as to dellect the incoming steam downward, a series of combining cones supported Within the condenser shell, and a plurality of nozzles for delivering cooling water from the water box to the said cones.

In testimony whereof I have hereunto subscribed my name this 17th day of September, 1917.
