NORMAN W. l/VHEELER, OF NEW YORK, N. Y.,
EJECTOR-CONDENSER.
SPECIFICATION forming part of Letters Patent No. 399,715, dated March 19, 1889.
Application filed May 8, 1888. Serial No. 273,232. (No model.)
To all whom, it may concern.-
Be it known that I, NORMAN W. WHEELER, a citizen of the United States, and a resident of the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Ej ector-Oondensers, of which the following is such afull, clear, concise, and exact description as will enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.
In ej ector-condensers of ordinary construction a very perfect adjustment of the parts is required for the steam of mingled condensing-water and condensed steam to exactly fill the throat of the condenser and bar regurgitation upward.
The obj ect of this invention is to construct an ej ector-condenser wherein the necessity of such nice adjustment of parts is avoided and which will to a certain extent be self-adjusting 5 and the invention consists in the devices and combination of devices as are hereinafter more fully described, and pointed out in the claims.
In the accompanying drawings, Figure l is a vertical section of an ejector-condenser embodying my improvement and is taken on the line y y of Fig. 3. Fig. 2 is a plan view of the same, while Fig. 3 is a horizontal section taken on the line 4r :r of Fig. l.
The steam to be condensed is brought by an exhaust-pipe (not shown in the drawings) to the branch B, whence it passes into the chamber F, and is turned downward through the throat G by the condensing-water. The condensing water is led into the condenser through the branch A under some pressure and iows from the nozzle O spread out in the form of an annular sheet or stream, by reason of the cone or conoid H being partly projected into the open end of the nozzle, and, covering with such moving annular sheet that part of H which is between the lower end of O and the throat G, passes through the throat G and downward through the retardngpipe l, and nally out through the chamber L and branch M. The pipe I is preferably trumpet shaped or flaring upon the proper curves for uniform retardation, and is partially occupied by the cylindrical extension N of the cone H. The
steam makes contact with the condensingwater as it iows in a thin conical sheet over the cone H, while steam and water have motion in nearly the same direction, so that the energy contained in the steam, and which is developed and made intense by the fact of instant condensation, is imparted to the annular stream entering the throat G.
The throat G contracts about the cone I-I, and also extends for a distance parallel or ap proximately parallel to the axis of the same, by means of which configuration the annular sheet or stream of water is made to change its direction in the throat to one parallel or nearly parallel with the axis of the cone, whereby it is thrown completely across the throat and at so small an angle that the throat is sealed against regurgitation whether the sheet is thick enough to completely fill it or not. Air contained in the exhaust-steam is carried through the throat by lateral action, so that a more or less near approach to vacuum is maintained above the throat when the device is properly worked.
For the purpose of adjustment, the cone H with its cylindrical extension N is fixed to the central guiding and supporting rod E, which rod moves vertically in the bearings D and K, so that the cone I-l may be raised or lowered to contract or enlarge the nozzle and throat simultaneously, and the parts may be fastened in any desired position by wellknown means; but the apparatus is capable of self-adjustment to a considerable extent by reason of the vacuum existing above the cone I-I, about its surface outside of the nozzle, and the plus pressure below.
The tendency of the resultant pressures being to raise the cone-cylinder and rod and close the nozzle and throat when the vacuum becomes strong enough to overcome the weight of the same, the stream of condensing-water will be reduced and the vacuum lessened, when the nozzle will again be opened and the vacuum again increased.
The degree of vacuum may be regulated within limits by the proper adjustment of weights to the loop I) at the end of the rod E.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
l. In an ejector-condenser, the combination IOO of a nozzle for admitting the condensingwater and a cone or conoid which projects within the nozzle, and also extends within the throat of the condenser, said throat being formed so as to contract about said cone, and also to extend parallel or approximately parallel to the axis of the same, whereby the stream of water is deflected and the throat sealed, substantially as described.
2. In an ejector-condenser, the combination of a nozzle for admitting the condensingwater, a cone or conoid which projects within the nozzle, and also extends Within the throatY of the condenser, said throat being formed so as to contract about said cone, and also to extend parallel or approximately parallel to the axis of the same, and an adjustable rod adapted to support said cone, whereby said cone is raised and lowered and the nozzle or throat contracted or enlarged simultaneously, substantially as described.
3. In an ej ector-condenser, the combination of a nozzle for admitting the condensingwater, a cone or conoid which projects within the nozzle, and also extends within the throat of the condenser, said cone being provided with a cylindrical projection and said throat being formed so as to contract about said cone, and also to extend parallel or approximately parallel to the axis of the same, a retardingpipe extending from said throat and surrounding said cylinder, and an adjustable rod adapted to support said cone, whereby said cone is raised and lowered and the nozzle or throat contracted or enlarged, substantially as and for the purpose set forth.
