To aZZ whom it may concern:

Be it known that we, the Honorable Sir CHARLES ALGEnNoN PARsoNs, K. O. B., a

subject of the King of Great Britain and Ireland, and residing at Heaton Works, Newcastle-upon-Tyne, and STANLEY SMITH Coon, a subject of the King of Great Britain and Ireland, and residing at Turbinia W'orks, lVallsend on-Tyne, both in the county of Northumberland, England, have invented certain new and useful lmprovements in Condensing Apparatus, of which the following is a specification.

This invention relates to improvements in condensing apparatus of the type in which a turbine or like chamber exhausts into a condenser having ordinary exhausting means connected thereto and to said cham her, and in which augmentor means for increasing the degree of vacuum in the condenser are connected to the conduit leading from the condenser to the ordinary exhaustlng means at the level to which the condensed fluid is permitted to rise' within the said chamber. In such an arrangement when the condensed and non-condensed vapors delivered from the augmentor means are withdrawn by the ordinary exhausting means it is found that the non-condensed vapors are liable to return to the inlet of the augmentor means instead of passing to the ordinar exhausting means, thus reducing the efficiency of'the plant. 0

The object of the present invention is to overcome this disadvantage,and to provide an improved condensing plant ofthis type.

The invention consists in condensing ap-.

paratus of the above type in which a device such as a liquid seal is provided in the conduit between the outlet from the augmntor means and the inlet to the ordinary exhausting means to prevent the return of the noncondensed vapors to the inlet of the augmentor means.

Referring now to the accompanying draw ing: Figure l is a sectional view of condensing apparatus arranged according to the present invention, while Fig. 2 is a sectional viewof a modified form of the apparatus. v

'Theinvention also consists in the improved condensing apparatus hereinafter described.

One method of carrying the invention into effect is illustrated by way of example as applied to the condensing apparatus illustrated in sectional elevation in Fig. 1. In this arrangement a steam turbine a exhausts steam into a conduit Z) leading to a condenser c,'from which'the water of condensation is removed through a conduit (1 by'ordinary exhausting means e, which usually consist in the ordinary type of wet air pump used in su'ch plant, and which in addition withdraws water of'condensation from the turbine chamber a by means of the pipe connection f.

The degree of vacuum thus produced in the condenser c is increased by .augmentor means g, forexample a jet and condenser which are connected to the condenser c by the conduit h. For the purpose of preventing the water of condensation rising to an undesirable at the levelm/m, to which such water to be permitted to rise within the turbine chamber. In such an arran ement, however, 4

it has been found that i the augmentor means 9 discharge through-a pipe connection it leading to'the inlet of the ordinary exhausting means e, the non-condensed vapors forming part of'this dischargeareliable to pass upward and through/theg'pipe connection is to the inlet of the augmentor means instead of passing directly to the inlet of the ordinary exhausting means e. In this way the efliciency of the condensing plant is considerably reduced. According to the present invention, however, this difficulty is overcome by arranging in the conduit at between the outlet of the augmentor- ,means 9 and the inletto the ordinary exhausting means 0, a devicewhich prevents the noncondensed vapors discharged from the augmentor means being returned to the inlet thereof. Such a device may consist,

for example, in an outer closed vessel p, which forms part of the connection between the outlet of the augmentor means 9 and the inlet to the ordinary exhausting means 6.

Direct communication between the main condenser c and-the ordinary exhaustin means e is provided by extending the vesse 79 some distance below the level rr of the inlet valves of the exhausting means 6. In.

this way the condensed vapor discharged from the augmentor means 9 will be col-' reea lected in the vessel 12, and form a m that rising to an undesirable height in the t-ur-' binechamber a.

In the case of condensing apparatus having between the main condenser 0831(1616 ordinary exhausting means 0 a single conduit with a branch connection is to the aug mentor means 9 as shown in Fig. 2, the conduit s is extended so as to project within the vessel 22 to the required distance below the level of the condensed vapor collected therein. As in the previous arrangement any noircondensed vapors discharged from the augmentor m ans aicdelivered intx) the liquid sealed space 9 in the vessel p, from which they are withdrawn directly by the ordinary exhausting means 6, and prevented from passing back to the inlet of the nag-mentor means g while the condensed vapors collected in the vessel 79 may still overflow into the conduit 76 for the purpose ct preventing the condensed fluid within the turbine chamber a rising above the predetermined level mm.

Obviously the device for preventing the passage of non-condensed vapors from the conduit n to that leading to the inlet of the augmentor means 9 may take many forms, it being only essential for the purpose ofthe present invention that such a device allows only the condensed'vapors discharged from the augmentor means to return to the inlet of the latter when required.

Having now described our invention, what we claim as new and desire to secure by Letters Patent is 1. An apparatus for obtaining a high degree of vacuum comprising in combination a motor, a condenser receiving the fluid discharged from said motorfeahausting means,

a pipe connection between the condenser and the exhausting means, a drainage pipe connection from the motor to the exhausting means, augmentor means having a connection to the connection between the condenser and exhausting means, said connection being made at the level to which condensed fluid is permitted to rise within the motor, a con nection conveying fluid from the augmentor means to the exhausting means and means by'which any uncondensed fluid which has already passed from the augmentor means to the exhausting means is prevented from circulating through the other pipe COIIHBC' tions back to the augmcntor means.

2. An apparatus for obtaining a high de gree of vacuum co nprising in combination a motor, a condenser receiving the fluid discharged from the motor, exhausting means, a pipe connection between the "condenser and the exhausting means, a drainage pipe connection from the motor to the exhausting means, augmentor means, a pipe connection between saidaugmcntor means and the condenser, an overflow pipe cohncction between the latter connection and the'ponneption between the condenser and exhausting means. said overflow connection being connected to the exhausting means pipe connection at the level to which condensed fluid is permitted to rise within the motor, a connection conveying fluid from the augmentor means to the exhausting means, and means by which uncondenscd fiuid'which has already passed from the augmentor means to the exhaust ing means is prevented from returning to the augmentor meansby Why of said overflow connection.

In testimony whereof, We aflix our signatures in presence of twowitnesses.
