HENRY N. WICKFIRSHAM AND WILLIAM HUSTON, OF WILMINGTON, DEL.
EXHAUST-NOZZLE.
SPECIFICATION forming part of Letters Patent No. 285,192, dated September 18, 1883.
' Application filed March 5, 1863. (ModeL) To all whom it may concern.-
Be it known that we, HENRY N. VVIOKER- SHAM and WILLIAM HUsroN, of Wilmington, NewGastle county, State. of Delaware, have jointly invented certain Improvements in Ejectors, of which the following is a specification.
Our invention is an improved exhaust-nozzle for creating draft by a steam-blast, fully described hereinafter, the device being specially adapted for use in locomotives.
In the drawings, Figure 1 is a cross-section through the smoke box and stack of a locomotive, showing our improved exhaust device applied thereto. Fig. 2 is a sectional plan of the device on the line 1 2, Fig. 1.
The essential features of the device are a tube, 12, which may be slightly conical or cylindrical, an inner concentric tube, a, above the upper edge of which the outer tube projects, and a casing of any suitable size and.
shape, containing a chamber, x, communicating with the annular space 3/ between the two tubes, and to which the exhaust-steam is admitted, said space or channel being inclined inward to throw the steam to the center of the tubes. The space w within the inner tube, a, is in free communication with the fluid to be propelledfor instance,the air or gases in the combustion-chamber of a locomotive; and we have found that when the exhaust-steam from the cylinder issues from the orifice g the air within the tube a is put into motion and is rapidly propelled in an unbroken column outward.
We are aware that an exhaustnozzle has been used in which the two tubes at and b are of equal length, but this construction results.
nular orifice,) and the annular casing A communicatin g with two diverging exhaust-tubes,
d d. This construction permits the exhausttherefore avoid the back-pressure that results from the ordinary constructions.
\Ve are aware that an ejector has been proposed with concentric pipes and an annular opening from which the steam is passed up ward to the chimney, our invention belng distinguished from this by the fact, first, that the steam is thrown toward the center of the pipe, insuring a much more effective action, and, secondly, by the fact that the annular opening is about equal in area to the exhaust, so that the ejecting actionissecured withoutany backpressuref lVe claim I 1.. An exhaust-nozzle consisting of an outer tube, a shorter inner tube, open at both ends, the two being arranged to leave an intervening space or channel, 0, equal in area to the exhaust-pipes, and inclined inward, and a casing containing a chamber communicating with said space, and an inlet-pipe whereby the exhaust is admitted to the said chamber, substantially asset forth. 7
2. The combination of the case A, tubes a and b, of different lengths, arranged -to leave an intervening channel, 1, inclined inward, and exhaust-pipes d. (1, arranged within a smokebox of a locomotive, substantially as set forth.
3. The combination, with alocomotive-boiler, of the tubes a 12, arranged withinthesmokebox to leave an intervening channel inclined inward, a casin g communicating with the space between the tubes, and exhaust-tubes d d, communicating with the casing, the tube 1) being extended through the shell of the smoke-box, substantially as described.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
