LOUIS SCHUTTE, OF PHILADELPHIA, PENNSYLVANIA.

JET-CONDENSER.

SPECIFICATION forming part of Letters Patent No. 344,502, dated June 29,1886.

Application filed March 6, 1886. Serial No. 194,255.

To all whom, it may concern:

Beit known that I, Louis SCHUTTE, of Phila` delphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvementsin Jet-Condensers, of which the following is a specification.

My present invention relates to improvements in the construction ofjet-condensers, and to the addition of parts which render the same generally applicable under varying conditions.

The improvements are designed more particularly for application to condensers of the type represented in Letters Patent of the United States granted to me on the 10th day of November, 1884, No. 330,157. In the patent referred to the live steam for the purpose of bringing water to the apparatus to inaugurate its operation or to assist induction while the apparatus was in operation was delivered in an annular jet within the waternozzle, while the guide of the central adjusting ram or spindle surrounded the latter. In my present apparatus I locate the steam-nozzle centrally within the apparatus and make use of the same as aguide for the ram. I also provide in the water-nozzle a communication with the atmosphere through a check-valve,

in order to obtain a st-ronger suction for the purpose of primingr or starting the instrument. I also provide, in connection with the water-supply pipe, a strainer having openings corresponding to the narrowest part of the water-passages, and also a second strainer with larger openings, to keep out the larger floating matters,which would tend to clog the apparatus, if admitted. To prevent the stoppage of the action in the event of the inflow of lowpressure or exhaust steam being stopped from the action of the engine-governor or from other causes, I provide an automatic valve, through which live steam will be admitted to maintain the action of the apparatus when necessary. I also provide the apparatus with a free exhaust-valve, which will open outward and permit the exhaust-steam to pass to the atmosphere, provided the operation of the condenser ceases.

Referring to the accompanying drawings, Figure l represents a longitudinal vertical section through the center of the condenser proper; Fig. 2, a side elevation of' the same,

together with its connections. Fig. 3 is a sectional view of the automatic valve for regulating the live-steam supply.

The body ofthe apparatus is constructed of substantially the usual form.

A represents an inlet-nozzle for live steam, its inner end arranged, as shown, to direct the same centrally through the apparatus in the direction of the discharge.

B represents the water-inlet nozzle, located under the delivery end of the steam-nozzle. At an intermediafe point in its length this nozzle is divided transversely, so as to form a radial opening, C, which communicates through au annular passage with an outlet valve or cock, a, opening to the atmosphere. This is preferably, as shown in the drawings, a check-valve provided with a hand-screw, by which it may be fastenedin a closed position.

D represents the combining-tube, into which the steam and water jets are delivered. This tube is provided, as in Patent No. 330,157, with a series of openings extending inward and forward in the direction of the delivery, for the purpose of admitting the exhauststeam from the surrounding chamber E (communicating by a side passage, I, with a checkvalve, J) to the central annular water-jet, the chamber communicating in` turn with the flanged mouth K, to which the pipe from the engine or other source of low-pressure steam is attached.

The cheek-valve J in the drawings is of the form represented in Letters Patent of the United States, No. 328,979, granted to me on the 27 th day of October, 1885.

Centrally through the combining-tube and the water-tube I extend the tapered regulating-spindle G, having a construction and mode of operation substantially identical with that in my Patent No. 330,157. The upper end of this spindle, instead of being guided as in the previous apparatus, is inserted within and guided by the live-steam nozzle A. That portion of the spindle which enters the nozzle is ribbed externally, made of angular section, or otherwise formed so that the live steam may pass around it into the apparatus. The lower end of the spindle is seated in and guided by a step, b, formed in one side of the discharge pipe or mouth of the apparatus M. The spindle is usually cast in a hollow or tubular form,

herewith, No. 188,941, and shown in Fig. 5. L

. pipe N', at any suitable point above its mouth,

`this valve I connect a pipe, T, passing to the with asmall opening through its lower end. An opening, c, is commonly extended from the step or guide b into the delivery-pipe of the apparatus, to permit the escape of any fluid which may indit-s Way into the interior of the spindle.

For the purpose of adjusting the spindle longitudinally, Imake use of a screw, d, entering its upper end and passing at the top through the body or casing to a hand-wheel, e, in the outer end.

For the purpose of indicating the position of the spindle, a rod, f, is attached to its upper end and passed centrally through the ad justing-screw, so as to project on the outside, the projecting nut being provided with suitable marks or graduations.

To the inlet-pipe N, which delivers the exhaust-steam, I connect the valve O, communieating with the atmosphere. This may be an ordinary check-valve opening outward from the steam-supply pipe; or it may be constructed in any other appropriate manner, provided onlythat it remains closed during the vtime that a vacuum is maintained within .the apparatus, but that it will yield to the external pressure and permit the escape of the steam to the atmosphere whenever the operation of the condenser stops, so that a vacuum no. longer exists.

To the starting-valve a, before alluded to, I? connect-a pipe, 7c, the mouth of which is sealed by immersion in water, as shown in Fig. 2. This pipe is used as an additional safeguard against leakage ofair through the valve a,` and to cause the condensation of the steam which may escape in starting the apparatus. At its upper end theWater-inlet nozzle is fashioned into or communicates with a water-supply pipe, N, which is carried downward be-.y low the surface of the water and provided at its lower end with a strainer, O, having very coarse openings or inlets. I also provide the with a second strainer, P, having smaller open- 1 ings. If desired, a check-valve, Q, may Vbei placed in the pipe at a suitable point to main-'- tain the water therein when the apparatus is; not in action. i

To the live-steam nozzle A, I connect the? live-steam pipe It, provided with the auto-i matic valve S. This valve may be of either by the pressure of tluid applied from an ex-i ternal source; but I recommend a valve of the.I particular construction represented in my ap-' plication for Letters Patent led of even date? To the operating or controlling chamber 'of' chamber E. Whenever the supply of exhauststeam is sucient to maintain Vthe operation ofthe apparatus and to maintain a vacuumil or partial vacuum in the chamber E, the valve S remains closed, thus preventing the admission of live steam. When from any cause thel operation of the condenser ceases, so that a vacuum no longer exists i-n the chamber E, the variation in t-he pressure or in the vacuum, communicated through the pipe T,will cause the opening of the valve S, thereby admitting live steam, to maintain the flow of water through the condenser untilthe exhaust-steam is again supplied.

It will be observed that under this arrangement the variations in the pressure or in the vacuum in chamber E are applied to control the admission of live steam.

WhileI prefer to employ the devices represented in the drawings to this end, it is to be distinctly understood that I may make use of a valve of any suitable character, opened or closed by external fluid-pressure derived from any appropriate part of the condenser.

For convenience in connecting the apparatus I form `the ends of the body into flanged mouths standing in planes at forty-tive degrees to its axis, and lto each of these I bolt a short pipe-section,curved in the arc of a circle embracing anY angle of forty-five degrees, so that by turning or reversing the end sections the mouth may be presented in position to connect with horizontal or vertical pipes, as required.

Having thus described my invention, what 'I claim is* Y 1. In ajet-condensing apparatus, as a means oi' automatically supplying live steam to maintain the action during the cessation of exhauststeam, the combination, substantially as described, of a steam jet condenser and a livesteam-supply valve connected by operating appliances with the vacuum-chamber of the condenser and controlled by variations in the vacuum or pressure therein.

2. In combination with a condenser of the type herein described, to be operated by exhaust or low-pressure steam, a valve to ad mit live steam to continue the action of the appa- .ratus during the temporary failure of exhauststeam, and devicesto open and close said live-- steam valve,connected with and controlled by the vacuum in the condenser, substantially as described and shown, whereby the live steam 'is automatically shut off during the continuance of the vacuum bythe exhaust-steam.

mission nozzle, the passage leading from the middle of the water-nozzle to the atmosphere, and a valve for closing said passage.

5. In a jet-condenser of the type herein shown, the Water-inlet nozzle, combined with the passage leading outward from an intermediate point in the length of said nozzle, and the dippipe connected to said passage, to

6. In a steam-jet apparatus, the combination ot" the inlet-nozzle and the regulating ram or spindle having one end guided by said nozzie.

7. In combination with a jet-condenser of the type herein described, an outwardlyopening exhaust, O, to permit the free escape of the incoming steam when the condensing Io action ceases.

In testimony whereofI hereunto set my hand, this 11th day of December, 1885, in the presence of two attesting witnesses.
