Nrrn TATES EXHAUST-NOZZLE.
SPECIFICATION' forming' part of Letters Patent No. 481,082, dated August 16, 1892.
` Application led April 6, 1892. Serial No. 427,986. (No model.)
To all whom t may concern..-
Be it known that I, CHARLES W. UMHoL'rz, of Bristol, in the county of Vashington and State of Virginia,have invented a new and Improved Exhaust-Nozzle for Locomotives, of which the following is a full, clear, and exact description.
My invention is an improvement in that class of exhaust-nozzles for locomotives in which a main central passage and a supplemental surrounding passage are provided for the steam. I make the nozzle proper independent of and detachable from the standpipe and support it upon vertical pins projecting from the top of the latter, which is also provided with a vertical flange that surrounds the base of said nozzle, but is separated from it by a narrow space, Which serves as the exterior or supplemental steam-passage. This construction and arrangement of parts provide a supplemental passage through which the steam has practically free exit, and also enables the nozzle proper to be readily detached when required for any purpose.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is a transverse section of the improvement as applied. Fig. 2 is a sectional side elevation of the improvement. Fig. 3 is an inverted plan view of the nozzle proper, and Fig. 4 is a plan View of the stand-pipe flange.
The stand-pipe A of the locomotive is connected in t-he usual manner with the exhaustpassages leading from the locomotive-cylinders, and the said stand-pipe may be single or have a division-Wall, as illustrated in Fig. 1. The top of the stand-pipe hasa horizontal ange A', in which are set vertical pins or bolts B, and on these pins the base C of the tapered nozzle D is supported. The latter is thus adapted to be readily detached-as, for example, when Worn out. The base-opening of the nozzle D .corresponds to the size of the top opening of the stand-pipe A. The base C of the nozzle D is supported by the pins B a suitable distance above the top of the standpipe A, and a vertical passage-way is formed between the edge of the base C and a vertical lange E, clamped or otherwise secured to the flange A of the stand-pipe. NOW it will be seen that the steam passing through the stand-pipe A enters the nozzle D, and part passes out through the upper contracted end; but a portion also passes through the passageway formed between the upper end of the stand-pipeA and the base C. The steam passing through this auxiliary passage is directed upwardly by the vertical flange E, so as to create a vacuum around the volume of steam issuing from the top of the nozzle D, thus acting as an ejector for the latter, thereby causing ready escape of the steam into the stack of the locomotive.
In order to spread the steam issuing through the upper end of the nozzle D, I provide an inverted cone F, the axial line of Which is in line with the vertical axis of the nozzle D. The cone F is made adjustable vertically, so as to move the same nearer to or farther from the upper contracted end of the nozzle D. For this purpose the cone F is supported on an arm F', projecting from a vertical bar F2, provided with rack-teeth F3, engaged by a segmental gear-wheel G, held on a shaft II, under the control of the engineer, so that by turning the said shaft the segmental gearwheel G moves the bar F2 up or down, according to the direction in which the said shaft I-I is turned. The up-and-down motion of the bar F2 causes a raising or lowering of the cone F, which latter thus moves farther' from or nearer to the upper end of the contracted nozzle D to spread the steam issuing through the said nozzle accordingly. As shown, the bar F2 is mounted to slide in suitable bearings I, projecting from the outside of the nozzle D.
It is understood that by the auxiliary passage between the top of the stand A and the base of the nozzle D only a light or no backpressure will be experienced in the stand-pipe A and the locomotive-cylinders, as all the steam will find a ready outlet both through the contracted end of the nozzle and the said auxiliary passage-Way. Itis understood that the nozzle D is held in place on the pins B by suitable keys or other means engaging the pins B, as shown in the drawings.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- In. an exhaust-nozzle for locomotives, the
IOO
combination, with the stand-pipe A, having as a supplemental steam-passage, and the inthe lateral top ange A', provided with the verted cone F, the mok-bar, and toothed seg- Io pins B, and a Vertical flange E, secured to the ment for adj listing it, as shown and described. top fiange, oi the detachable nozzle D,having a ianged base C, which is supported in fixed CHARLES W. UMHOLTZ. position upon said pins and surrounded by Witnesses: the said Vertical fiange, between which latter A. A. HOBSON,
and seid nozzle is an annuler space serving JOHN A. FERG.
