Description

UNITED Seimas FFICE.
ATENT JAMES LEVIS, OF CHICAGO, ILLINOIS, ASSIGNOR TO HIMSELF AND EDWARD J. CUYLER, OF SAME PLACE.l
IMPROVEMENT IN EXHAUST-NOZZLES.
Spccilication forming part of Letters Patent No. 116,605, dated July 4, 1871.
To all whom it may concern:
Be it known that I, JAMES LEWIS, of Chicago, in the county oi' Cook and State ot' Illinois, have invented a new and useful Improvement in Exhaust-Nozzle to Steam-Engines; and l do hereby declare the followin g to be a full, clear', and exact description thereof, which will enable others skilled in the art to make and use the same, ret'- enence being had to the accompanying drawing lorming part ot' this speciiication, in which- Fig'ure 1 is a side elevation ot' an exhaust-nozzle embodying my invention, and Fig. 2 is a vertical central section ofthe same.
Similar letters ot' reference indicate like parts in both iigures ofthe drawing'.
Myinvention relates to an automatic exhaustnozzle to be attached to the exhaust-pipe ot.' loconlotive-engines 5 and has for its object to prevent ashes, cinders, tvc., from entering the cylinder through the exhaust-pilie, therebyprotecting the workin g surfaces from injury; and the invention consists in the method otl securing the valve to its seat within a suitable case attached to the end of the exhaustspipe, whereby the action of the exhaust steam, when it opens the valve, shall not break or inj ure its connections with the seat.
In the aceompanyii1g drawing, A is an annular plate, which is iirmly secured to the end ot' the exhzilust-pipc. B is a c vlindrimll case, which is securely bolted to each side ofthe upper surface oi" plate A, as shown at C. D is the valve, consisting ot' a hollow cone, which is bisectcd, as shown at E, iorming two independent sections, l d, which rest upon plate A within the case.
Each section is provided at its base with a triangular' projection, e, arranged centrally upon its periphery and in line parallel to its central edge, and resting within a corresponding recess, f, formed in the upper surface ot' plate A, tWereby orming a center upon which the respective sec tions are oscillated when opened by the action of the exhaust steam, the sides ofthe recess being' formed to admit ofthe movement. The outer surface ofthe separate sections l (I are each provided with a curved or irregular-shaped lug, l1, which extend through slots formed in opposite sides of case B, thereby preventing lateral displacement ofthe respective sections when in operation. 'lhe steam escaping from the exhaustpipe opens the valve by forcing sections d (l outward at their upper ends, and whichoscillat-cs upon the projections e, allowing' the steam to escape through the valve.` which then close by their own gravity after the .jet or' steam has escaped, thereby preventing ashes, cinders, Sie., from entering the pipe.
I-Iaving thus described my invention, what I claim as new, and desire to secure by Let-ters The bisected conical valve l) provided with projections e e, in combination with plate A provided with reeessesjfj, and arranged to operate substantially as and for the purpose described.
The toregoing specification oi" my invention signed by me this 14th day of April, A. I). 1871.
fitnessesz JAMES LEVIS.
