Description
UNITED 'STATES PATENT @Prion WILLIAM EBBITT, OF NEW YORK, N. Y.
IMPROVEMENT INl STEAM-NOZZLES.
Specification forming part of Letters Patent No` 140,902, dated July 15, 1873; application iiled April 30, 1873.
To all whom tt may concern:
Be it known that I, WILLIAM EBBI'IT, of the city, county, and State ot' New York, have invented a new and Improved Steam- Nozzle; and I do hereby declare the following to be a full, clear, and exact description thereof7 which will enable those skilled in the art to 'make and use the same, reference being had to the accompanying drawing forming part of this specification, which drawing represents a longitudinal central section of my invention.
This invention relates to a steam-nozzle which is provided with conical spout that is a, situated in line with th eXhaust-pipefand fits `"into the mouth-piece of he nozzle, leaving between its outer surface and the inner surface of said mouth-piece an annular space that communicates with the steam supply-pipe in such a manner that steam admitted through said supply-pipe rushes out through the annular space between the spout and mouthpiece, and by the current of steam thus created the air in the spout and in the exhaust-pipe is rareed. The conical spout is secured in position by means ot a screw'thread, or other equivalent means, so that it can be moved in or out, and that the annular space between said spout and the mouth-piece can be regulated, the mouth-piece being fitted into a socket formed in a iiange on the body of the nozzle, so that access can be had to the conical spout, and the annular space between the spout and the mouth-piece can be adjusted without disturbing the connecting-pipes.
In the drawing, the letter G designates my steam-nozzle, which connects by a pipe, H, with the steam-boiler, and by a pipe, I, with the space from which the air is`to be exhausted. The steam-pipe H leadsinto a chamber, n, from the center of which rises a conical spout, J that is situated in line with the exhaust-pipe I and extends up into the mouth-piece K of my nozzle.. Said mouth-` I piece is also tapering, and the steam admitted through the pipe H rushes out through the annular space o between the spout J and the mouth-piece K, and as it passes outof this annular vspace it carries with it a portion of the air contained in the spout J, and thereby the air in the exhaust-pipe I is raretied. `A check-valve, p, Which is situated between the spout J and the exhaust-pipe I prevents the steam from passing into said exhaust-pipe, and when the air in the spout is rareied by the current of steam, this valve opens, and the air in the exhaust-pipe is allowed to rush ont. The spout J is secured in the chamber n by means of a screw-thread, or any other equivalent means, so that it can be adjusted up or down, and that the annular space o can be increased or diminished, according to the pressure of steam injected through the pipe H. On the body of the nozzle Gr is formed a ange, p', forming a socket for the reception of the bottom ilange of the mouth-piece K, which is secured in position by screws g. By this arrangement I am enabled to get access to the spout J whenever it may be desired without being obliged to disconnect the pipes H or I, and I can adjust the spout J with ease and facility.
What I claim as new, and desire to secure by Letters Patent, is-
The body of the nozzle G, formed with a.
lange, p', in combination with the mouthpiece K and adjustable spout J, all constructed and arranged to operate as shown and described.
This specilication signed by me this 26th day of April, 1873.
WIM. EBBITT.
