HIYURAETS b Patented May 16, 1944 Maria Luisa Trucco dc Cazen'ave, Buenos Aires, Argentina Application November 27, 1941, Serial No.- 420,705 -'In Argentina November 30, 1940 4 Claims.

This invention refers to an improvement in lamps or night-lamps, burning kerosene or oil, and adapted to burn all night long, while producing a slight illumination of the room. The chief characteristic of this invention is a hollow shield conforming to the lamp, whose position can be changed in accordance with the intensity required for the flame.

This shield, which is placed in an inverted position, has a central orifice with a member through which the wick passes, which according to its position, graduates the light, and has several openings through which the air requisite to feed the flame may pass, together with a ring for the tube, thus preventing a draft from putting out the flame, and aiding satisfactory combustion.

The lamp is also provided with a conical horizontal partition placed in the container for the liquid fuel and this prevents the fuel from being spilled when the lamp is moved, and also serves to fill the lamp therewith.

In order that this invention be well understood, and also be easily put into practice, drawing thereof is attached hereto, in which- Fig. 1 shows this improved lamp, in section, with the shield placed in a low position, so as to permit the maximum intensity of the flame.

Fig. 2 is a partial view, similar to the foregoing, but the shield is shown to be effective to reduce the flame.

Fig. 3 is a section taken on the line IIIIII in Fig. 1.

Fig. 4 is a projection of the section IV--IV of Fig. 1.

Fig. 5 discloses a side elevation of the capsule alone.

Fig. 6 is a section taken on line VI-VI in Fig. 5.

The construction of the lamp, in accordance with the invention now to be described, has a container l for the liquid fuel and is provided at its upper part with an inverted cone 2 at whose vertex is formed an orifice 3.

The cone 2 is provided with adjusting devices 2 for adjustment inside the container I, as may be seen in Figures 1 and 3.

The cover 4 of the container 1 has a cylindrical part 5 at its top, and at its side the devices 6, whose purpose will hereinafter be explained. In its centre is located a small tube 1 serving as a holder for a wick 8.

The shield 9 is made so as to be capable of attachment to the cylindrical part 5 by means of a screw 10 so as to screw in upon the same, and coincides with the devices 6 above mentioned.

The hollow shield 9 has in its centre an orifice H with a member serving to direct thefiame upwards, and acting as a guide for the flame of the wick.

Around the shield are a group of orifices l2, through which the air requisite for perfect combustion passes.

Moreover, around said shield 9 is a sort of support formed by two concentric rings I3a and No, the first of which fixes the shield 9, while the second is separated from the first by the members l3.

The support, thus constituted, is preferably unitary or made in one piece.

The device just described is used for accommodating a shade, or a chimney for the lamp, to protect the flame, and as an ornament.

As shown in Figures 1 and 4, for this purpose we have the tube I l, made of transparent and incombustible material, and provided with the pieces I5 for its support. The tube i4 is arranged so as to rest on the support referred to, i. e. on the devices l3 and above the rings, I31) and l3a, and receives the shade I6, fixed at its top part. The shade l6 may be made of any material suitable for that object, although the lamp might only be provided with a tube M, or

other equivalent.

The container I may be provided with a plate, as shown in Figure 1 at 1a.

The lamp is used in the following manner:

When a high flame is required, the shield 9 is placed in a low position, as shown in Figure 1, so that the wick 8 slightly overlaps, through orifice I I giving the maximum of light.

To obtain a low light, the inverse must be done, i. e. the shield 9 should be raised, unscrewing it from the cylindrical piece shown in Figures 2 and 5, so that the end of the wick remains low, and the flame emerges, small, through the orifice 4. A current of air runs through the orifice I2 and openings between the pieces 13, so as not to extinguish the flame.

The use of the tube I4 ensures a perfect flame, without any smoke, and showing the blue tinge of good combustion. The edge or ring i3b allows the tube I I to be held in position in proper relation to shield 9, preventing any movement towards the side.

The cone top 2 of the fuel magazine allows fuel to be easily introduced, and prevents its spilling when the lamp is moved about.

It is evident that certain modifications might be resorted to without altering the characteristics of this invention, as clearly indicated in the following claims.

Having now fully described my invention, I claim:

1. In a fuel burning lamp having a magazine or container for liquid fuel and a wick therefor, the combination of a concave top upon said magazine having the lowest part thereof located toward the center with a central opening therein,

a generally round cover for said magazine fitted into the latter and having a top upon the upper surrounding at least the upper portion of said wick tube with a central aperture for a flame upon said wick, there being additional orifices in said shield, and a ring or annular projection upon said shield for supporting a lamp chimney, shade or the like.

2. A lamp according to claim 1, having projections upon the ring for supporting a shade or the like.

3. A lamp according to claim 1, having the h concave top of the magazine substantially forming an inverted truncated cone, and having the end thereof and a wick tube projecting'vertically through the center and extending down toward the central opening in the concave top of the magazine when the cover is in place thereon, a wick extending through said tube down into said magazine, a shield adjustably mounted upon and MARIA LUISA TRUCCO DE CAZENAVE.
