UNITED STATES PATENT UFFI E.
ADOLPH F. PRAI-IM, OF INDIANAPOLIS, INDIANA.
VENTlLATlNG-JACK FOR LANTERNS.
SPECIFICATION forming part of Letters Patent No. 698,053, dated April 22, 1902.
Application filed May 2, 1901. Serial No. 58,410. (No model.)
T0 at whom it may concern:
Beitknown that LADOLPH F. PRAHM, acitizen of the United States, residing at Indian apolis, in the county of Marion and State of Indiana, have invented a new and useful Ventilating-Jack for Lanterns, of which the following is a specification. v.
Myinvention relates to an improvement in that class of lanterns used in the open, and especially that class of railroad-lanterns subjected to great wind-velocity.
The object of my invention is to provide a ventilating-jack for lanterns which may be used at the upper end of any of the usual lantern-bodies and of such construction as to monly used in railroad service for switchlights, outside train-lights, &c.
The open upper end of the body 1 iscovered by a jack, the peculiar construction of which constitutes my invention. This jack consists of a short cylindrical body 2, to the lower end of which is secured an outwardly and downwardly flaring flange 3, the edge of which fits within theupper end of the lantern-body 1. The upper end 4 of the body 2 is flared outwardly and upwardly and provided with a number of ventilating openings or perforations 5. Depending from the upper end of portion 4 is a flangeG, which extends considerably below the perforations 5. Extending upward from the upper end of portion 4 is a cylinder 7, provided with perforations 8, and hinged to-the upper end of cylinder 7, at one side thereof, is a cap 9, corrugated, if desired, provided at its center with a depending cylinder 10, to which is at tached a bell 12, havinga central perforation 13, opening into the cylinder 10. Securedto the lower end of the body 2, so as to form a part thereof, is aninwardly and downwardly flaring flange 14, provided with perforations 15, leading into the interior of body 2. Se
cured to the lower end of flange 14 is a cylindrical shell 16,, which projects upward through body 2 to and above the upper end of portion 4, and preferably flaring at its upper end, as
at 17. Extending across the upper end of portion 4 is an annular imperforate plate 18,
which extends to and is secured to the shell vided with a central opening, which is eX- tended upward by means ofthe cylindrical shell 22, said shell extending up to the upper end of the flaring portion 17 of the shell 16. Secured to the upper end of the flaring end 17 of shell 16 is a bell 23, which extends over the upper end of shell22 a short distance from the upper end thereof, a free passage for gases from the shell 22 being provided beneath the edge of the bell 23. By the arrangement of shells 16 and 22 an annular passage 24 is formed around shell 22.
In operation the fresh air strikes the exterior of body 2 and is deflectedupward, passing into the interior of said body through the perforations 5, and is deflected downward by the imperforate plate 18. This air passes downward through perforations 15, and a major portion thereof is deflected outward by the flange 19 and passes down beyond the edge of the bell 21 and into contact with the flame. A portion of the fresh air, however,
passes through perforations 20 and up through the passage 24, thus keeping theshell 22 comparatively cool. rectly upward through shell 22 and pass out over the top of said shell and from beneath the bell 23, passing out either'through the perforations 8 in the leeward side of cylinder 7 or passing up through perforation 13 of bell 12 and from thence out through perforations 11 and out from beneath the corrugated cap 9. Fresh air also enters the perforations 8 on the windward side, but said air passes directly through the body over the tops of the shells 16 and Y22, thus aiding the draft, but not of such character as to cause any flicker of the lights.
I claim as my invention 1. In a ventilating-jack for lanterns, the combination with a cover adapted to close theupper end of a lantern-body, of a tubular The burned gases pass dimain body having a series of openings leading therein near its upper end and openings leading from its lower end inside the cover, a shell-of less diameter than the body mounted therein and leading upwardly therethrough, a second open-ended shell mounted within the first shell and extending therethrough, an annular plate or bell closing the lower end of the annular space between the two shells, openings leading to the interior of the first shell near its lower end, and an annular imperforate plate connecting the upper end of the main body to the first shell.
2. In a ventilating-jack for lanterns, the combination with a cover adapted to close the upper end of alantern-body, of a tubular main body having a series of openings leading therein near its upper end and openings leading from its lower end, a shield protecting the upper openings, ashell of less diameter than the body mounted therein and leading upwardly therethrough said shell having openings leading to itsinteriornearthe lower end, a second open-ended shell mounted within the first shell and extending therethrough, an annular plate or hell closing the lowerend of the annular space between the two shells,
and an annular imperforate plate connecting the upper end of the main body to the first shell.
