JOHN STEPHENSON, OF NEV YORK, N. Y.

TRAWl- CAR LAMP -HOUSE.

SPECIFICATICN forming part of Letters Patent No. 378,469, dated February 28, 1888.

Application filed June 9, 1887. Serial No. 240,838. No model.)

To all whom it mag concern:

Be it known that I, J OHN STEPHENSON, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in TramCar Lamp-Houses, of which the following is a specification.

Tram-cars with high windows require different construction of the lamp-houses and the parts of the car connected therewith, because the glass in the sash and the head-rail of the sash must be elevated nearer to the car-roof, causing displacement of parts of the lamphouse and obstructing the air-ducts through which the lamp receives its supply of air; also requiring a different construction of the back wall of the lamp-house and of the silvered glass reflectors, and that the lamp-house be of less height, and its door more arched and hung at the top with hinges made especially for the purpose, so that one end of the door may be raised to a greater extent, corresponding approximately with the plane of the carceiling. This construction of the lamp-house entrance and door-hanging is necessary in order that the lamp and its chimney may read ily be put in place, and also that when the door is lifted it will automatically catch and be held up by the suspension-hook, and again, when unhooked, the door will fall and automatically latch itself close to prevent the blowing out of the light or sluggish combustion and dull light with bad odor from the lamp.

The drawings illustrate so much of a tramcar as will aid a ready understanding of the present invention.

In said drawings, Figure 1 is a sectional elevation of a portion of the end of a car looking from its interior, showing particularly its lamp-house. Fig. 2 is a like view showing the lamp-house door in its opened position, and Fig. 3 is a vertical section taken on the line ac of Fig. 1.

In carrying out my invention I reduce the width of the floor 20 of thelamp-houseL at its rear edge suflieient for the window-sash E to pass up behind it, and make the back wall, 21, to rise vertically above the upper edge of the raised sash, and thence horizontally over the top edge of the sash to the sub top rail, 11, to which the back wall is fastened. This back wall is airtight, so that the air supplying the lamp-ilan1e must enter the lamp-house through the air-ducts 8 in the lower edge of the end head-panel, 10, and upper edge of the end sub top rail, 11.

The door 15 of the lamp-house is of less height than those heretofore employed, and its top rail more arched and being at the top provided with hinges 16 17, in the former of which the knuckle is elevated considerably above the jamb of the door, so that when it is raised, as in Fig. 2, the door will be inclined approximating that of the ear-roof B, in which position it is held by the suspension-hook 18. The door 15 is held tightly closed by a springhook, 14.

I claim- 1. A tramear having a lamp -house the door of which is hinged on a line approximat- 7o ing the plane of the car-roof, so that the outer end of the door may swing higher than the end toward the side wall of the car, as and for the purposes described.

2. A tram-car with the fioor of its lamphouse lessened in width to make space behind the floor for the upraised end sash, and the lower section of the lamp-house back wall with the end sub top rail constituting the side walls and ceiling of a chamber occupied by the head-rail of the end sash, as and for the purpose described. 1

3. A lamphouse having a door hinged at the top, with the hinge-joints at an angle with the horizon, the hinges having limbs secured to the head-rail and stile of the door, so that when the door is open it will conform some what to the plane of the car-ceiling, as and for the purposes described.

A. A train-car lamp -house with its doorhead arched and hinged at an angle corresponding to the shape of the car-roof, the hinge made of curved form,with limbs to fasten to stile and head-rail of the door, as and for the purpose described.

5. A tram-car with its lamp house constructed with a floor cut away at its back edge and its rear wall rising therefrom vertically for a desired distance, and thence hori- In testimony whereof I have signedhlyname zontally till it cont-acts with the sub top rail, to this speeificationin the presence of two subto which it is properly secured to be air-tight, scribing witnesses.
