EMILE BOESOH, OF SAN FRANCISCO, CALIFORNIA.

LAMP.

SPECIFICATION forming part of Letters Patent No. 576,716, dated February 9, 1897.

Application filed $eptember 10, 1894. Serial N01 522,625. (No model.)

To all whom it may concern.-

Be it known that I, EMILE BOESOH, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Lamps and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to certain improvements in car-1am ps of that class which is fixed in the side or end of the car and adapted to give light upon two or more sides. It is also applicable to light streets or houses, with various forms of burners, known as Argand or chimney burners, either for oil or gas.

It consists in certain details of construction, which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a vertical section taken through the lamp, showing its attachment in the end of a car so as to light the interior and also the platform from opposite sides. Fig. 2 is a view showing the application to an Argand gas-burner.

One of the objects of my present invention is to provide a lamp or lantern frame without casing, globe, or door, open at the upper end to connect with the feed-air, which is supplied from above, and having a passage or passages whereby the air is conveyed to a point around or below the lamp and delivered upwardly to the burner. It also contemplates a construction of the feed and exhaust air passages in such a way that the two bodies of air are united, so as to balance any irregularities or variations of pressure caused by the wind or arising from other sources.

WVhen exposed to draft, chimney-burners for oil or gas have heretofore been protected by a casing of metal and glass, or glass entirely, like a globe, but they are apt to smokeor go out under strong draft or a gale of wind, and the same result occurs in burners which are used without a chimney and protected'by a casing or globe.

In my improved reflector-lamp I have shown the invention as adapted for use upon a streetcar; but the improvements may be used in any connection where they are available.

Ais a lantern-body which is made, as shown in the present case, of sufficient size to receive the oil-fount and chimney, and this body is adapted to be secured to the interior of the woodwork of the car. A hole of sufficient diameter is made through the side of the car, and the part A, which is of smaller diameter than A, passes through the woodwork and incloses an opening through which the light of the lamp is directed upon the platform exterior to the car. Between the two parts A A is the conically-shaped reflector O,which faces the interior of the car and is inserted level with the woodwork, so that a chimney and burner-socket only project beyond. Within this annular reflector-rim is formed a passage D, which serves to allow the air from above to pass down around the exterior of the reflector and to be delivered to the bottom around the base and oil-fount E of the lamp, and from this point the air is delivered up through the interior of the wick-tube and also within the chimney exterior to the wick-tube, so as to provide supply of already-heated air for the combustion of the oil.

In the present case I have dispensed with all inclosing glass bodies exterior to the lamp, and thus avoid the obstruction of such glass, as well as the difficulty of obtaining access to the lamp.

The oil-fount E is placed into and over the burner-socket.

The burner F is surmounted by a glass chimney G, the base of which rests upon a soft washer of any suitable material, which serves to form a tight joint to prevent the entrance of air directly around the base of the chimney from the outside, and also forms a cushion H to prevent the breakage of the chimney by sudden shake or jar.

I I are springs which press slightly against the exterior of the chimney to steady it and assist in retaining it in place.

A perforated cylindrical screen J surrounds the burner, and through this the air, which is admitted from below, is delivered around the burner.

The upper end of the chimney G connects with the extension-chimney K by means of a funnel-shaped flaring mouthpiece K, into the diverging open end of which the upper end of the chimney is adapted to fit, the diameter of this funnel being such that it will accommodate itself to chimneys of various sizes. This extension-chimney K slides within an exterior guiding-tube L of sufliciently larger diameter to allow it to move freely. This tube is enlarged, as shown at L, and has an intermediate shoulder against which the upper end of a spiral spring M. presses, while the lower end of the spring rests in an outwardly and upwardly turned flange in the bottom of the cone K, so thatthe spring exerts a pressure upon the extension-chimney K to retain the funnel K constantly in contact with the upper end of the chimney.

I xterior to the extension-chimney K and the guide-tube L is a concentric air-passage formed by a tube N of large diameter, which incloses the upper part of the extension K, and the guide-tube L, extending downwardly around them, and from the upper part of the a tube N a funnel-shaped hood 0 extends outwardly and downwardly, this again being surmounted by a cap P, as shown.

The whole is fixed upon the top of the car and supported by an exterior flanged tube Q.

Openings or passages R admit air around the exterior shell, between the hood 0 and the deflecting-flange R, allowing it to pass upwardly, as shown by the arrows, through openings in the upper end of the tube Q, and thence downwardly between this tube and the tube N, the air passing thence into the passage D around the annular reflector, and being eventually delivered into the inclosed air-chamber around and below the fount E, whence it is delivered to the burner, as previously described.

The flange It serves to deflect the wind and dust which sweep along the roof of a car when in motion, and thus protect the air-inlet passages.

As heat and cold will expand and contract the metal somewhat, a small space is allowed between the extension-tube K and the guidetube L, which allows an easy telescoping joint at this point. Any air which may enter through this joint from below will be led upwardly to a point where it rises up with the exhaust-air or may go downwardly with any unusual pressure of the feed-air.

The overhanging tube N is made of larger diameter than the extension-chimney K and its guide, and, as before stated, surrounds the upper end of both, and within this tube the feed-air and exhaust-air may unite, thus acting as a sort of counterbalance to counteract any excessive air pressure from the outside.

The three air-chann els previously described have distinct uses. The outer one is for the admission of the teed-air, the inner oneis for the escape of the exhaust-air and products of C0l11l)LlS'tlO1l,Wl1ll6 the intermediate one serves as a point where the currents of feed and exhaust air both meet.

In Fig. 2 I have shown the application of my invention to incandescent and Argand gas-burners in which the lower part of the burner is inclosed in a easing into which the feed-air is admitted, as shown at I). From this chamber or casin g part of the air min gles with the burning gas necessary for the incandescent light. The chimney G is sup ported in the usual manner by elastic springs I, resting upon the soft base or washer H,upon the chimney-holder or skirt CL of the burner, covering the air-chamber into which the feedair is admitted through the passage D. From this chamber air passes up within the chimney and exterior to the burner through openin gs between the supporting ribs or bars S of the chimney-base. Gas is admitted through the pipe T, which has an extension-tip T, delivering into the perforated convex hood U, from which the gas escapes through the perforations into the suspended mantle V. Around the base of the tubular tip T is an inclosing hood IV, which is open at the bottom to allow air to enter it from the air-chamher, and the tube T has openings X made in the side within this hood, so that the air may enter the tube T and flow upwardly with the gas with which it is thus mixed and delivered with the gas through the perforated hood U to supply the burner.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a lamp-fixture, the combination, of a body consisting of a hollow vertical or side reflector, the eXtension-chinmey to which it is connected, said body having feed and exhaust passages and an air-chamber, open on top, a removable fount, having its lower part fitting into and over the said air-chamber and pr0- vided with a burner, and a glass chimney fitted to the burner and having its upper part fitting within the chimney extension.

2. I11 a car side lamp-fixture, the combination, of a body consisting of a vertical or side reflector having an air-passage behind the reflecting-surface, said body being without glass casing in front or surrounding the reflector, and having its lower portion projecting inside of the car and formed with an airchamber in communication with the air-passage, and open on top, a removable fount' to be fitted into the open top of said air-chamber, and a burner and chimney carried by the fount.

3. In a la1np-fixture,the combination,of the body consisting of a vertical or side reflector having an air-passage behind the reflecting surface said body having its lower portion projecting into the car-body and forming an air-chamber in communication with said passage, a chimney extension and means for supplying air to said passage, the fount adapted to be fitted within the open top of the airchamber so that its lower portion is inclosed thereby, a burner and aglass chimney to protect the flame and conduct the draft from the fleeting-surface and having its lower portion In witness whereof I have hereunto set my projecting into the ear and formed with an hand.
