and Felix Suchetzki, all of Remscheid, Germany, asslgnors to Job. Vaillant KG, Remscheid, Germany Filed Nov. 12, 1959, Ser. No. 852,387 Claims priority, application Germany Nov. 24, 1958 Claims. (Cl. 158106) This invention relates to a commonly found arrangement in Bunsen burners for gas devices, such as gas water heaters, in which a gas nozzle is exchangeably insorted in the gas supply pipe for the burner and the mixmg tube of the Bunsen burner is fixed to the gas supply pipe centrally above the nozzle, leaving an air-admission opening. In the case of such Bunsen burners, it is necessary to be able to remove the mixing tube of the Bunsen burner easily in order to clean the gas nozzle or to exchange the nozzle body. On the other hand, the fixing of the mixing tube must ensure a central position of the mixing tube in relation to the nozzle aperture. Various constructions are known which, although they fulfil these requirements, are excessively expensive to manufacture.
The problem underlying the invention is to provide a cheap mounting clip for the mixing tube which is suitable for mass production and which, on the one hand, renders possible a removal of the mixing tube without the assistance of tools and, on the other, results positively in a centering of mixing tube around the nozzle.
According to the present invention, this problem is solved by providing a clip, which centers itself on the nozzle body, with upwardly bent lugs which carry the mixing tube, and which straddles the supply pipe with two downwardly bent legs which are drawn tight by a detachable clamp beneath the pipe. The holder is in a form which may be made as a simple structural part punched and stamped from sheet metal. No fixing rails or attachments need be applied to the supply pipe. In addition, simple nozzle bodies may be employed. In the case of a plurality of Bunsen burners, which are fixed according to this invention side-by-side to the same distributing pipe, it is simple to remove any single burner and attach it again conveniently.
The invention may be carried out by providing the legs of the clip, which straddle the supply or distributing pipe, with hook-shaped ends, over which the clamp is pushed in the direction of the axis of the pipe.
The clip should engage the mixing tube of the burner in a manner to stay with it when the latter is removed. Hence, the clip should be shaped to slip from the pipe, after its clamp is removed, preferably without flexing beyond its elastic limit.
The clamp can be provided with a screw bearing on the pipe for tightening the clip. However, if a screw is provided, it is especially advantageous that the legs, which straddle the pipe, have pocket-shaped punched-out portions, over which can be pushed a U-shaped clamp which is provided with corresponding openings and is tightened by a screw that rests on the supply pipe. A centering of the clamp is then effected at the same time by the pocketshaped punchedout portions. In addition, the legs and the clamps are not strained on bending, so that distortion of the parts by inexpert handling, for example, strong tightening of the clamping screw, is impossible.
Three examples of embodiment of the invention are represented in the drawings and Will be hereinafter described.
FIG. 1 is an elevation, partly in section, of a Bunsen burner showing one form of clip according to the present invention;
atnt
Patented Sept. 4, 1962 FIG. 2 is an elevation, perpendicular thereto, also partly in section;
FIG. 3 shows another embodiment of clip for the Bunsen burner;
FIGS. 4 and 5 show a third example of embodiment of the invention in two elevations which are perpendicular to each other; and
FIG. 6 shows, on an enlarged scale, a section through the clip of FIGS. 4 and 5.
Although the following disclosure ofiered for public dissemination is detailed to ensure adequacy and aid understanding, this is not intended to prejudice that purpose of a patent which is to cover each new inventive concept therein no matter how others may later disguise it by variations in form or additions or further improvements. The claims at the end hereof are intended as the chief aid toward this purpose, as it is these that meet the requirement of pointing out the parts, improvements, or combinations in which the inventive concepts are found.
The Bunsen burner consists, in the known manner, of a mixing tube 1 (FIG. 1), that is open at the bottom and which may be flared in a funnel-shaped manner, and may have a soldered-on burner head 2. Pressed out at the lower part of the mixing tube 1 are two pockets 3 and 3 which are opposite each other. Lying in these pockets 3 and 3' are the upwardly bent lugs 4 and 4' of the clip 5, the ends of which extend out through slots in mixing tube 1 and may be upset or otherwise permanently retained. The clip 5 has an aperture snugly receiving nozzle 6 so that clip 5 is centered on the nozzle body 6 which is screwed into a gas supply or distributing pipe 7. The clip 5 also has two downwardly bent legs 8 and 8' which straddle the distributing pipe. The bottom ends 9 and 9' of the legs 8 and 8' are stamped to a hook-shape and project downwards to beyond the distributing pipe 7 or beyond its diameter if it is round. Pushed laterally over these hook-shaped ends, i.e., in the direction of the axis of the distributing pipe, is a clamp 10, preferably resilient, by means of which the legs 8 and 8 are pressed toward each other and drawn around the wall of the distributing pipe. After the clamp 10 has been removed, the clip 5 can, together with the Bunsen burner 1, 2 fixed thereon, be pulled off upwards on the supply pipe 7 with no more than resilient flexing of legs 8, 8'. The clamp 10 may also be replaced by a clamp 10 with a clamping screw 11 (see FIG. 3) which is supported at the bottom of the distributing pipe 7.
In the example of embodiment according to FIGS. 4, 5 and 6, the Bunsen burner likewise consists of a mixing tube 21, that is open and flared at the bottom as well as having a soldered-on burner head 22.
Pressed out at the lower part of the mixing tube 21 are two pockets 23 and 23 which are opposite each other. Lying in these pockets are the upwardly bent lugs 24 and 24 of a holder or clip 25, which are soldered to the mixing tube 21, although they could be secured otherwise, as in FIG. 1.
The clip has an aperture snugly receiving nozzle 26 and by which it is centered on the nozzle body, which is screwed into a supply or distributing pipe 27. The clip also has two downwardly bent legs 23 and 28 which straddle the supply pipe. The ends of these legs terminate approximately at the bottom edge of the supply pipe 27. Approximately at the level of the top third of the distributing pipe 27, there are provided, on the two legs 28 and 28, pocket-shaped punched-out portions 29, 29, the cut edges 35, 35 of which are facing upwards and the sides of which are tapered to merge obliquely downwards into the plane of the legs. Sprung over these punched-out portions from the bottom to the top is a resilient U-shaped clamp 30 which has openings 31 and 31' on its two sides respectively. These openings have upper crosspieces 32 and 32' respectively which extend in the direction of the axis of the supply pipe and are parallel to the cut edge of the lugs. When the clamp is being pushed on, its arms 34 and 34' slide over the punched-out portions 29 and 29', widening it resiliently, in order finally to snap in on to the cut edges 35 and 35. These cut edges have originally been cut out arcuately upwards in the plane of the lugs, in order that, after the cut edge has been punched out, it will not be concave on its upper surface. If required or for providing a safety factor it may be even a little raised at its center. The clamp 30 can be drawn against the upper faces 35, 35 of the punched-out portions 29 and 29' by means of a clamping screw 36 which rests on the underside of the supply pipe 27 and moves in the screwthread of a nut 37 which is nonrotatably arranged between the two arms 34 and 34' of the clamp.
For the purpose of dismantling, the screw 36 is loosened, the U-clarnp 3%} is sprung open by hand to such an extent that the clamp 34} may be twisted or dropped down and removed. Then the Bunsen burner, with clip 25, can be lifted off. Upon being restored, the clip fits nozzle 26 to ensure centering of mixing tube 21 around nozzle 26.
The tightening of the screw is then possible only when the U-clamp 3% has again been sprung over punched-out portions 29 and 29'.
In order to prevent the screw 36 from being completely unscrewed out of the nut 37, the end of the screw-thread is pinched.
