CAR-LAM P.

SPECIFICATION forming part of Letters Patent No. 416,170, dated December 3, 1889.

Application filed May 3, 1888.

To all whom it may concern:

Be it known that I, JOHN KIBBY, J12, of Dayton, county of Montgomery, and State of Ohio, have invented certain new and useful Improvements in CaeLamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates more particularly to hanging lamps for vestibules in railway-cars; and it consists in the improved construction and combination of parts of a car-vestibule lamp, as will be hereinafter fully described in the specification, illustrated in the drawings, and more particularly pointed out in the claim.

In the drawings, Figure l is a vertical section through that portion of the roof of a railway-car which covers the platform'and the dome which forms the ceiling of the vestibule, with my improved lamp and a smoke-jack shown in half-section in their operating positions. Fig. 2 is a partial plan view of the reflector,taken on the line 3 of Fig. 1. Fig. 3 is a partial plan view of the under side of the vestibule-dome and the lamp. Fig. 4 is a similar view to Fig. 1, with the oil-fount and globe removed from their holders. Fig. 5 is an enlarged broken perspective view of the globe and chimney holders and a portion of the reflector. Fig. (3 is a horizontal section and partial plan view of the lamp, taken on the line 2 2 of Fig. at. Fig. 7 is an enlarged perspective view of the hurricane-dome de tached from the reflector. Fig. 8 represents the oil-fount detached from the lamp.

Similar letters of reference indicate corresponding parts in the several figures.

A, Figs. 1 and t, represents the end of a railway-car, B the outside curved roof, and C a dome with an opening in its center formed over the platform in which to place a lamp, as shown.

D is asmoke-jack or ventilator attached to the roof, through which the products of combustion escape to the open air.

E is a reflector, preferably corrugated, and provided with a number of apertures F to admit of a circulation of air around the upper portion of the lamp and surmounted by a screw-threaded collar G and dome l-I.

Serial No. 272,724. (No model.)

I is a cap covering the outlet for the products of combustion.

J is a collar surrounding the neck of the dome H and covering the apertures F to prevent snow or rain that may pass through the smoke-jack from reaching the globe.

K is a hollow screw-threaded cylinder, which engages with collar G, and is provided with flange L, having rim M.

N represents holes in cylinder K for the escape of hot air inthe globe.

O is an elastic chimney-holder of any known form connected to the lower end of hollow cylinder K and engaging the top of the chimney, as shown in Fig. 1.

P is the globe surrounding the burner.

Q is an annular sheet-metal ring having a projecting flange-ringlt, upon which the globe rests when in position for use.

S is the base-ring, such as is common in car-lamps, and to which ring Q is attached.

T, Figs. 1, 3, L, and 6, are supporting-hangers, any number of which may be employed. The upper ends of these hangers are secured to the under side of the dome or ceiling. and also secured to the reflector, as shown in Figs. 1 and 4, and their lower ends are secured to the base-ring S.

U represents holes pierced in ring Q for the admission of air to the interior of the globe for the support of combustion.

V is the oil-founi', V the burner, and X the lamp-chimney.

Y is a space formed beneath the car-roof by the dome or ceiling, reflector E, and end of car A. a

It will be seen from the drawings that the dome-shaped or recessed ceiling admits of the lamp being suspended above the bell-cord, and, together with the reflector, forms a large space between it and the car-roof. It will also be seen that the dome surmounting the reflector is independent of and entirely disconnected from the outer smoke-jack. The products of combustion must therefore first enter the space Y before passing through the smoke-jack to the open air; hence irregular motions of air in the smoke-jack cannot affect 100 the flame, since they also must first pass into space Y, where they become quiet; nor can rain orsnow that may be driven through the smokejack reach the globe or chimney of the lamp, thereby causing frequent breakage, for by this construction a direct communication between the lamp and the open air is avoided. I consider the construction of smokejack shown to be best; but any known form may be used. I v

I am aware that it is not new to construct a lamp With a detachable globe, and that a hurricane-dome above the lamp is not in itself new, and I do not claim such constructions broadly.

In my application for an improvement in car-vestibule lamps, filed May 25, 1888, Serial No. 275,066, I have shown a lamp similar to the one forming the subject-matter of this application, except in that case the supports are adjustable, Which is the feature that separates and distinguishes that case from this one.

Having thus fully described my invention, WhatI claim as new, and desire to secure by Letters Patent, is

In a car-vestibule lamp, the base-ring S, provided with a suitable holder for the globe, supporting hangers or brackets for rigid attachment to the ceiling, a globe, a reflector having a screw-threaded neck, as G, said reflector being also provided With openings F and surmounted by dome H, having cap I and collar J, a hollow screw-threaded cylinder K,

having flange L, rim M, elastic chimney-holder O, and openings N,in combination with a recessed ceiling, as O, roof B,leaving the space Y, and an outlet to the open air for the passage of the products of combustion through a smoke-jack, as D, the Whole to operate sub- 35 stantially as set forth.
