IMPROVEMENT IN EJECTOR-CONDENSERS.

Specification formingr part of -Letters Patent No. 178,434, dated June 6, 1876 application tiled February 17, 1876.

. To all whom it may concern Be it known that I, J AMES F. GUTHEIE, of Somerville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Ejector-Gondensers, of which the following is a specification:

This invention relates to ejector-condensers, which are used to condense the exhaust steam from steam-engines, and entirely dispense with the air-pump; and the invention consists of a peculiar construction and combination ofparts, which will be fully. hereinafter described, and specifically pointed out in the claim.

In the accompanying plate of drawings, Figure l represents a vertical cross-section of an ejectorcondenser having my improvements attached thereto; Fig. 2, ahorizontal cross-section on lille x x, Fig. 1; and Fig. 3 is a horizontal cross-section of the water-conduction tube on line y y, Fig. 1.

A in the drawings represents an ejectorcondenser, of which B is the inlet for steam U, the inlet for water; D, the discharge-pipe, and E the induction-tube; Iand F, the conduction-tube for the passage of the water after it hasenteredatinletOto thecombining-chamber Gr; H, the plug in conduction-tube F, to regulate the liow or quantity of water, all as ordinarily in ejector-comlensersnow in use, and therefore needing' no further description herein. I is the discharge-nozzle ofconduction-.tube F. This discharge-nozzle I is formed substantially as shown, and is adapted by a screwthread, a, to be screwed on or oli' of conduction-tube l".

When the steam in the ruiming of the engine is ot' a high` pressure at the point of exhaust, for a complete and effective action of the water upon the steam in -the working of the condenser, a larger surface of water must be exposed in the combining-chamber for contact with the steam, and, obviously, when the steam is at a lower pressure at the exhaustpoint, a corresponding decrease of the surface of the water is necessary.

The discharge-nozzle I, in its position as shown in the drawing, is adjusted for a high pressure of-steam at the exhaust-point, exposing to the steam a greater surface of the column of water passing through the condenser, as the end b of discharge-nozzle I is at a greater distance from the bottom of combining-chamber, and when the steam at the eX- haust point is at a low pressure, by unscrewing the discharge-nozzle accordingly as the steam is more or less of alower pressure at the exhaust-point, the discharge-nozzle can be adjusted to the requirements of the ejectorcondenser, as is obvious.

' L, an opening or hand-hole in the casing at d of the condenser, and covered b v the cap M, which is adapted to be readily removed when desired.

To adjust the discharge nozzle I to its proper work through the opening or handhole, a rod or wire can be inserted into one of' the holes, c, in the periphery of dischargenozzle I, which can then be easily turned to its proper adjustment.

Bythe use of this hand-hole L, the breaking otl joints ot' the condenser is avoided, and the discharge-nozzle can be adjusted without interfering with its operation or the running of the engine. n

In adjusting the discharge-nozzle I to the pressure of steam at the exhaust-point, the plug H is also accordingly regulated to maintain the sa mequantity ot'water passing through discharge-nozzle.

N is a stuffing-box, to prevent leakage of steam or water through the joint a ot' discharge-nozzle I and conduction-tube F, which would interfere with the working of the condenser.

' This improvement is applicable to condensers for steam-pumps, and also as well to injectors of boilers; but when used in injectors, the pipes connecting with the injector must be arranged so that the steam will enter inlet C, and the water inlet B.

I am aware of the patent to Robinson and Gresham, dated May 29, 1866, and I disclaim the construction therein shown.

Having now described my in 7ention, what I claim, and desire to secure by Letters Patent, isfl In an ejector-condenser, having the handopening L and conductor-tube F, the adjustable discharge-nozzle I, having the recesses c, by which it is adjusted through the handopening L, substantially as described.

The above specification of my invention signed by me this 31st day of January, A. D. 1876.
