Abstract

The invention is a gas lamp with a gas mantle employing butane, propane, etc., supplied from an independant source of gas via a flexible pipe. The lamp is a reversible type which functions equally well in downwardly directed or upwardly directed position, having good illuminating performances when the burner is directed downwardly. An elongated tubular sleeve (8) is continuously disposed around and spaced from the burner (2), and is mounted at an end on the cover (7) and at the other end on the cup(9), the ear (9a, 9b) for evacuation of the fumes remaining outside the sleeve.

FIELD OF THE INVENTION The present invention relates to gas lamps and, more particularly, to gas lamps having a gas mantle by combusting butane, propane and the like supplied from a separate gas source via soluble pipes.

French Patent 412,697 describes a gas lamp consisting of the following parts:

A burner having an elongated tube consisting of an inlet (mixing chamber) which mixes combustible gas and combustion promoting air and an outlet (nozzle) which is intended to be covered by a gas mantle.

The burner penetrates, but is in seamless contact with the burner (e.g. screwed to the burner tube), located between the inlet and outlet of the burner and three outlets are formed for the discharge of the combustion gas. And an annular cup that extends almost perpendicular to the burner.

The cover is located between the cup and the burner inlet, with the burner penetrating its center and making no contact with the burner, with the convex portion facing the outlet of the burner.

An injector (or gas connection) with one end connected to the inlet of the burner and the other end to a device for supplying combustible gas.

Glass for protecting the device which removably secures the gas mantle to the gas mantle and cup.

The present invention is not limited to the gas lamp of the above form, but relates to a gas lamp of a portable type that can operate similarly well when directed downward or upward.

Shangtae's gas lamp with the burner outlet facing upwards is simply placed on the horizontal plane by the above-mentioned cover, and it can be simply suspended by the burner outlet facing downward.

For this gas lamp, the expression "reversible" is used in the present specification.

The object of the present invention is to work equally well in such a reversible form of gas lamp, i.e., in either up or down direction, and especially when the outlet of the burner is directed downward, nevertheless design And a gas lamp having a relatively simple structure.

According to the present invention, the basic structure of the gas lamp consists of a sleeve, a cover, and a cup surrounding the burner at a predetermined distance away from the burner, wherein the sleeve has a cover (a base when the outlet of the burner faces upwards). The other end is an elongated tubular sleeve that connects to the cup.

An outlet for discharging the combustion gas is formed outside the sleeve.

The burner also passes freely through the cup through an opening adapted to fit in the cross section of the burner formed in the cup.

According to the present invention, localized heating in the cover can be prevented, whereby the position of the air inlet can be kept in the cover.

In fact, the burner penetrates the cup and cover so that little heat is transferred to the cup and cover.

Therefore, when the outlet of the burner is directed downward, a significant amount of heat from the combustion gas is absorbed by the cup and the cover so that it no longer diffuses through the burner tube to receive combustion-promoting air.

Because of the above-mentioned reasons, the tubular sleeve portion of the gas lamp is relatively cold, so that the gas lamp can be easily held even while in operation.

Referring to the drawings, the present invention can be understood in more detail.

FIG. 1 shows a gas lamp which can be fixed vertically to the ceiling of a room by a suspension device 1 shown in dashed lines as described in patent application No. 8019595 of 5 September 1980.

The gas lamp shown in FIG. 1 essentially includes a tubular elongated burr 2, one end of which is connected to a curved gas inlet connector 3, the other end of which is a flexible gas mantle. The ring in which the groove | channel 2a provided to support (4) is provided is comprised.

At one end of the burner connected to the gas inlet connector 3, two combustion-promoting air inlets 2b are provided at adjacent positions of the gas injector 5 screwed to the axial portion of the gas inlet connector 3. 2c) is formed.

The gas inlet connection is fixed by a transversely extending bridge 6 which is fixed by suitable means inside the cover 7 which forms the base of the gas lamp when the gas lamp is placed on a horizontal plane.

The burner 2 passes through the opening 7a formed in the cover 7 at a constant interval such that there is almost no thermal contact between the burner 2 and the cover 7,

The cover 7 is fixed to the tubular sleeve 8 surrounding the burner 2 at a distance from the burner 2 with the convex portion facing the outlet of the burner, with a slot at one end of the sleeve 8. An 8a is formed, and a protruding portion 8b configured to enter the corresponding hole of the cover 7 is formed at the end.

In a known manner, the protrusions are inserted into the corresponding holes of the cup of the cover and then twisted to secure the tubular sleeve and the cover.

The other end of the sleeve has a similar formation, that is, has a projection 8d or the like of the slot 8c.

The protrusions 8d are inserted into corresponding holes formed in the cup 9 and the deflector 10 to join the two parts and the sleeve.

In the horizontal surface portion of the cup 9, two outlets 9a, 9b are formed on the opposite side in the radial direction, and two screens 10a, 10b configured on the current transformer 10 are located thereon.

At the center of the horizontal portion of the cup 9 of the current transformer 10 are respectively provided central through portions through which the burner 2 can freely pass.

The central through portion of the cup 9 is denoted by reference numeral 9c.

The gap between the burner 2 and the cup 9 and the current transformer 10 is such that the gap between them is as low as possible and the gap does not provide a large passage for the combustion gas generated during combustion. It is.

The cup 9 detachably supports the glass 12 by two stirrups 13 and 14 fixed to the cup, the glass 12 being in contact with the corresponding surface of the cup 9. do.

The metal parts cut out to form the outlets 9a and 9b of the cup are bent with their edges toward the center to form a hanging piece 9d for supporting the clip 15, and one side is supported by the groove 2a. The clip 15 is fitted into the groove 16a of the fragment 16 fitted to the other end of the gas mantle 4.

The opening 7a formed in the cover 7 has a shape as shown in FIG. 2, that is, composed of one circular portion and two notches opposite in the radial direction and thus ribs of the burner 2. (rib) allows the integration of (2d) and (2e).

Although the present invention has been described herein with respect to only one embodiment, it should be understood that the present invention is not limited thereto and other variations similar to the scope of the present invention.
