EXHAUST-NOZZLE FOR LOCOMOTIVES.
SPECIFICATION forming part of Letters Patent No. 442,767, dated December 16, 1890.
Application filed March 15, 1890. Serial No. 344.011- (No model.)
To all whom it may concern;
Be it known that 1, JOHN J. DE LANOEY, of
Binghamton, in the county of Broome anddescription.
The objectof the invention is to provide a new and improved exhaust-nozzle for locomotives, serving to regulate the exhaust of the engines, and thereby regulating the draft in the boiler.
The invention consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and pointed out in the claims.
Reference is to be had to the accompanyin g drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is aside elevation of the improvement as applied to a locomotive, parts being broken out. Fig. 2 is an enlarged plan view of the improvement. Fig. 3 is a transverse vertical section of the same. Fig. at is a sectional side elevation of the same on the line x a: of Fig. 2, and Fig. 5 is a plan view of a modified form of the plate.
The improved exhaust-nozzle A is provided with a plate B, fitted onto the upper end of the exhaust-pipe O, which may be double, as is illustrated in Fig. 3, or singlethat is, the two exhausts of the engines of the locomotive running into a single exhaust-pipe.
The plate B is provided with apertures D of the same size as the apertures at the upper ends of the exhaust-pipe C, so that when the plate B is in a central or normal position the apertures D of the plate B fully register with the openings in the end of the exhaust-nozzle. The plate B is fulcrumed in its middle on a pin E, projecting from a bar F, supported on brackets G, secured to the sides of the exhaust-pipe (J, the said plate being held in place on the brackets by nuts ll, screwing on the threaded ends of the said brackets G, as is plainly illustrated in Fig. at. The pin E, after passing through the plate B, also passes a short distance into the top of the exhaustpipe 0, so as to form a secure bearing for the plate B. On the top of the latter, at its sides in the middle, are arranged offsets I, onto which fits the under side of part of the bar F in such a manner that the plate B is free to turn on its pivot E, and at the same time is held securely against the upper end of the exhaust-pipe O o prevent the plate from being lifted upward by the force of the exhauststeam.
From the plate B projects to one side an arm J, pivotally connected by a link K with a lever L, fulcrumed on the outside at the frontend of the locomotive-boiler, the link K passing through the said front end. The le- Ver L is also pivotally connected by a link N, extending along the outside of the locomotive, with a lever O, pivoted on the cab of the 10- comotive and extending into the same so as to be within convenient reach of the engineer in charge of the locomotive. The lever O is adapted to be locked in place in any desired position by the usual arrangement connected with a notched segment P, as shown in Fig. l.
Nhen the lever 0 stands in a vertical position, as illustrated in the said figure, the openings D in the plate B fully register with the openings in the exhaust-pipe O. In this position the exhaust-steam can pass freely out of the exhaust-pipe 0 through the smokebox and smoke-stack of the locomotive, so as to cause considerable draft in the fire-box of the boiler. \Vhen it is desirable to increase the amount of draft in the fire-box of the 10- comotive, the engineer in charge of the locomotive operates the lever 0 either forward or backward, so that the lever Lswings and imparts a swinging motion by the link K and the arm J to the plate B, which latter moves across the top of the exhaust-pipe O, and part of the openings of the latter are cut off or diminished in size, so that the exhaust of the engine is retarded, and consequently the draft in the smoke-box and smoke-stack is increased, so that a'consequent increase of the draft takes place in the fire-box of the locomotive.
It will be seen that the two openings in the exhaust-pipe are diminished in size alike by moving the plate B, and it is immaterial in which direction the engineer moves the lever O, as the cut-off takes place either Way. When the exhaust-pipe O is single, the plate B is preferably arranged as shown in Fig. 5, having but one single opening D, and pivoted at one end to the pin E-and provided at the opposite end with the arm J. A segmental slot Q is also formed on the plate B, and into it I claim as new and desire to secure by Letters Patent- 1. The combination, with an exhaust-nozzle havlng an unobstructed open upper end or outlet, of a flat plate B, having an unobstructed opening of the same size as the noz zle-outlet and pivotally connected with the nozzle to one side of its outlet to vibrate'horizontally thereacross, substantially as set forth.
2. The combination, with thedouble nozzle, of a vibrating plate B on top thereof and provided with two apertures the same in size as the outlets of said nozzle, a pivot connecting the said plate between its apertures with the nozzle between its outlets, and a cross-bar under which the center of said plate works, substantially as set forth.
3. In an exhaustmozzlc for locomotives, the combination, with a bar-secured to the sides of the exhaust-pipe and a pin projecting from the said bar, of a plate pivoted loosely on the said pin and provided with apertures adapted to register With the openings in the exhaustpipe, and projections formed on the top of the said plate to engage the under side of the said bar, substantially as'sho'wn and described.
4. In an exhaust-nozzle for locomotives, the combination, with a bar secured to the sides of the exhaust-pipe and a pin projecting from the said bar, of a plate pivoted loosely on the said pin and provided With apertures adapted to register With the openings in the exhaustpipe, projections formed on the top of the said plate to engage the under side of the said bar, an arm projecting from the said plate, a lever pivotally connected with the said arm, and a second lever under the control of the engineer in the cab of the locomotive and pivotally connected with said first-named lever, substantially as shown and described.
