Application led November 24, 1915. Serial No. 63,174.

To all whom t may concern.'

Be it known that I, LINDSLEY Serrure/Lons, la citizen of the United States, and residing at Hasbrouck Heights, in the county of .Bergen and State ot' New Jersey, have invented an improvement in Lighting Ap.- paratus for Railway-Gars and the like, of

which the following is a specification.

This invention relates to lighting apparatus for railway cars and the like.

One of the objects thereof is to provide apparatus of the above type of simple and practical construction and eiiicient action in which the emission and direction of light are so controlled as t0 especially adapt it for use in sleeping cars.

A more specific Objectis to provide apparatus of the 'above type in which a' sleeping car is effectively illuminated for ordinary use and yet the light so controlled as to improve sleeping conditions.

@ther objects will` be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which Awill be exemplified in the structure hereinafter described, and the scope of the -application or' which will be indicated in the following claims.

In the accompanying drawing in which isshown one of various possible embodiments of this invention. Figure 1 is a sectional elevation. Fig 2 is a diagrammatic plan of electrical circuits. Fig. 3 is a diagrammatic section of a portion of a railway car.

Similar reference characters refer to vsimilar parts throughout the several views of the drawing.

Referring now to Fig., l of the drawing,

there is shown at 1 a supporting casting or spider which may be bolted to the car roof as at 2. Threaded within and extending cluster 4.

downwardly from the member 1 is a tube 3 on the lower end of which is secured, as by suitable threaded A, connection, the lamp Fitted tightly to the car ceiling indicated at 5 is a canopy 6 which rests upon a sleeve ,7, in turn supported by a fitting 8 held upon the tube 3 by the lock nuts 9. Ilihe outer surface of the fitting 8 has threaded thereon.

mounted centrally of the aisle t at 9a a' collar l10 provided with an inner tapering surface 11 adapted as the collar is screwed downwardly, to contact the springtwo in number but which may be of any desired number or candle power. In `a socket 17 at the lower end of the cluster and having dilerent electrical connections as hereinafter described, there is mounted' a bulb 1S. Screwed about the threaded member 19 of the socket 17 is a reiiector 20 which is of such nature that it does not transmit liOht from the bulb 18 therethroughto any considerable extent and is vpreferably substantially opaque. This refiector is so formed as to throw the light from the bulb 18 in a downward direction with slight divergence of the rays. The lower end of reflector 20 fits closely within the upturned lip 21 at the lower edge of the globe 15, suitable packingbeing employed between these parts to prevent rattling, if desired. It is to be understood that the globe 15 is translucent and may be formed of an opal or frosted glass, and it is also to be understood that the term globe `is used throughout in a broad sense to denote a translucent member mounted about a source of light whether in fixed relation thereto or removable therefrom.

The different 'lights are preferably supplied from a suitable source of current as the battery 22, and the circuit of theu bulbs 1G is controlled as byV the switch or cut-out 23, whereas the circuit of the bulb 18 is separately controlled by a switch 24, all as shown in Fig. 2 of the drawing.

As shown in Fig;- 3 of thedrawing, the apparatus set forth in Fig. 1 is preferably 25 of a sleepingV car, the curtains being indicated at 26 and the usual berths at .27'. As indicated at 28, the light from the reflector 20 is 'thrown I downwardly to 'illuminate the aisle, and substantially excludes from its path both the upper and lower berths of the car, although y a portion of the curtains including the section numbers is to some extent illuminated.

The parts within the globe may be assembled or taken apart in the following manner. Assuming tliatthe parts are as shown in `Fig. 1 and it is desired to remove one of the bulbs 16, the bulb 18 is first unscre'wed and thereupon the reflector 2O unscrewed and withdrawn. The bulbs 16 are then readily accessible through the lower 'opening in the globe 15 and if desired, the latter may be removed by first taking .out the bulbs 16 and thereafter loosening the gripping members about the lip 14. The

parts may be assembled in the reverse order.

The action of the above described apparatus ig substantially as follows: In normal use, that is, when it is desired to illuminate the car, the switch 23 and if, desired the switch 24: also, are closed. lThe bulbs 16 then radiate light through the globe 15 and illuminate. the entire car interior, the aisle being especially illuminated by the bulbs 18, it being understood, that a series of these fixtures are preferably installed centrally along the aisle of the car. lVhen however certain of the berths are occupied, the switch 23 is opened and the illumination confined to the bulbs 18. rlhe light from this series is thrown substantially down along the car aisle which is the only place where it is needed for those retiring later. The concentration of this light which, by the way, is not necessarily of great intensity, prevents any material illumination of' the berths and leavesl them in substantial darkness.

lt will thus be seen that there is provided apparatus in which thel several objects of this invention are achieved and in which the above and other advantages may be attained. The entire apparatus is of' simple and inexpensive construction and is readily assembled and taken apart, and yet the villumination of' the car is so controlled as well to meet all conditions of practical use.

`As various possible embodiments of the above invention might be made and as various changes might be made in the apparatus above described, it is to be understood that all matter herein set forth is to vbe interpreted as illustrative and not in a said source into said aisle substantially shad# ing said berths, a sourceof light mounted above said car aisle between said berths adapted to throw light toward said berths,-
