Definitions

  • the present invention relates to gas lighting devices, and more particularly to combustible gas lamps (butane, propane, etc.) with an incandescent sleeve, supplied from an independent gas source, by means of a flexible pipe for example. .
  • gas lamps of the above type portable or not, intended to operate directed downwards, either as sconces on a vertical surface (wall for example), or as lamps fixed on a horizontal face (ceiling for example).
  • the lamp is generally mounted at the end of a metal tube having an appropriate conformation (for example, angled in the case of a wall lamp, or straight in the case of ceiling lighting), fixed at the other end on the surface in question, and used for the transport of combustible gas or an air-gas combustible mixture.
  • French patent 323,220 it is proposed to double the burner tube with an outer tube, screwed on one side to a collar of the burner tube, and provided on the other side with a disc (separate from the cup) in the vicinity and above the incandescent sleeve.
  • This outer tube provided with fins, forms a stagnant air gap with the inner tube of the burner.
  • the solution according to this patent makes it possible to radiate the heat captured by the disc, while isolating the burner tube.
  • the invention relates to gas lamps of the aforementioned type, of the portable type, which can operate both upwards and downwards. In the upward position, these lamps are simply placed on a horizontal surface, for example by means of the bell defined above, forming a base, and in the downward position, they are simply suspended. Such lamps will hereinafter be called “reversible”.
  • None of the gas lamps conforming to the prior art and examined above is suitable for reversible use, on the one hand because no base is provided for placing the lamp on a horizontal surface with the burner directed towards the high, and secondly because there is no provision for manually and conveniently grasping the lamp with the hand, in particular when the latter is in operation or has just operated.
  • the subject of the present invention is a lamp of the reversible type, that is to say one which can operate indifferently in the position directed downwards or directed upwards, having good light performance when the burner is directed downwards, while remaining relatively simple in design and construction.
  • the support structure of the lamp consists of a framework external to the burner tube, comprising an elongated spacer continuously and remotely surrounding the burner, on which the bell is mounted on one side (forming a base when the lamp is directed upwards), and on the other side the cup, the smoke exhaust opening remaining outside the spacer, while the burner freely crosses the cup through an orifice adjusted to the section local of said burner.
  • a gas inlet connector on which the injector is screwed and secured inside the bell and on the other hand the burner is engaged on the fitting and freely crosses the bell through an orifice adjusted to the local section of said burner.
  • the burner crosses the cup and possibly the bell without significant thermal bridge with these elements.
  • the cup and the bell collect a significant part of the heat of the combustion fumes, so that this heat can no longer diffuse towards the combustion air inlet via the burner tube.
  • the spacer allows good grip of the lamp, including when it is in operation because for the reasons explained in the preceding paragraph, this part of the lamp remains relatively cold.
  • a gas lamp which can be fixed to the ceiling of a room, in a vertical position, for example by means of a suspension device shown in broken lines under the reference 1.
  • the lamp illustrated in fig. 1 essentially comprises an elongated burner 2 having a generally tubular shape with convergent-divergent, one end of which is forcibly engaged around a bent connector 3 for the gas inlet, while its opposite end constitutes a ring provided with 'A groove 2a for retaining a flexible incandescent sleeve 4 whose attachment will be described later.
  • the end of the burner which is associated with the elbow connector 3 has two openings 2b, 2c for combustion air inlet at the level of which there is a gas injector 5 screwed into the axial branch of the connector 3.
  • the latter is integral with a transverse bridge 6 secured by any appropriate means inside a bell 7 constituting the base of the lamp when it is placed on a substantially horizontal surface.
  • the bell in question firstly comprises an axial ferrule 7a in which a notch 7b has been made intended for the passage of the supply pipe of the connector 3; the ferrule is extended by a frustoconical part with a concave rounded profile referenced 7c ending in a horizontal face or bottom 7d closing the bell 7.
  • the burner 2 crosses the above-mentioned face in an opening 7e with a limited clearance such that there is no significant thermal contact between these two elements, as indicated above.
  • the bell 7 is subject to a tubular spacer 8 continuously and remotely surrounding the burner 2, the two edges of which are notched so as to form cutouts 8a extending so that their ends form legs 8b intended to penetrate into corresponding perforations from the bottom 7d of the bell 7.
  • the other end of the spacer is similarly shaped, that is to say that it includes cutouts 8c and tabs 8d. The latter penetrate into openings made in a cup 9 and in a deflector 10 so as to twist these two parts together with the spacer and the bell 7.
  • the base of the cup 9 is provided with two diametrically opposite openings 9a, 9b above which two screens 10a, 10b are placed, arranged in the deflector 10, and which are placed between the cup 9 and the bell 7.
  • the terminal edge of each screen advantageously projects beyond the extreme edge of the corresponding hearing.
  • the central part of the deflector is offset upward so as to form with the outside of the base of the cup 9 a space in which is placed a flexible seal made of refractory mineral fibers referenced 11.
  • the central part of the deflector 10 and the base of the cup 9 are each provided with a central perforation allowing the free passage of the burner 2.
  • the perforation of the cup 9 is referenced 9c.
  • the central hole of the seal 11 has a diameter smaller than that of the burner in order to '' prevent any passage of combustion gases at this level.
  • the cup 9 supports a glass 12 thanks to the action of two fixing stirrups 13, 14 secured to it by means of the deflector 10 which traps them against the corresponding face of said cup.
  • Part of the metal cut in order to constitute the evacuation openings 9a, 9b of the cup is folded down in the direction of the center in order to constitute claws 9d which hold a clip 15 intended to support a nozzle 16 in the groove 16a from which comes engage the extr mite of the sleeve 4 opposite to that which is retained by the groove 2a of the burner.
  • the endpiece 16 is supported by the curved end 20c, above the outlet 2a of the burner 2, with a longitudinal bracket 20 which freely rotates through the cup 9 and the bell 7.
  • This bracket is recalled towards the 'input 2b of the burner 2 by a spring 21 bearing on one side against the bottom 7d of the bell 7 and on the other side against a stop 20b belonging to the bracket; moreover, a strike 20a forming a stop keeps the bracket 20 in abutment against the cup 9, under the effect of the spring 21. It is thus possible to laterally move the nozzle 16 relative to the outlet of the burner 2a, so as to facilitate the removal of a used sleeve or the fitting of a new sleeve.
  • Fig. 2 shows the flexible pipe 17 which cooperates with the “end” or transverse branch 3a of the connector 3 with a view to supplying the burner 2.
  • the ferrule 7a is provided with two notches 7b arranged diametrically opposite and each obtained by cutting and bending horizontally with a tongue assigned the reference 7f.
  • the burner 2 is obtained by means of two stamped metal shells, applied one against the other and crimped together so that it comprises over its entire length two diametrically opposite ribs referenced 2d, 2e.
  • the 7th opening made in the face 7d of the bell 7 is presented as illustrated in FIG. 3 that is to say it affects the shape of a buttonhole comprising a circular part and two diametrically opposite lateral notches allowing the passage of the ribs 2d, 2e.
  • the rib 2d has a notch 2f in which engages a cambered part 15a of the clip 15 in order to determine the axial position of the burner (fig. 4).
  • said clip comprises a U-shaped base, the transverse web of which has the above-mentioned arched portion 15a.
  • said clip comprises a U-shaped base, the transverse web of which has the above-mentioned arched portion 15a.
