IMPERIAL

PATENT OFFICE.

The present innovations relate firstly to the fastening of the heating or regenerative body respectively the connection of the same to the burner and the bell jar, secondly to the ignition device.

Fig. Ι ist.ein vertical section and

Fig. 2 is a horizontal section of a regenerative lamp, while

Figures 3 and 4 show the ignition device separately.

• I. Attachment of the heating or regenerative body.

Sämmtliche parts of the lamp are carried by the hollow serving as the gas line and held together arm e. The lower part of this arm carries the burner, as well as the ignition device and the bell jar, while the radiator is detachably attached to the upper part.

Most regenerative lamps have the bell jar cemented to the radiator to hold it in place, making the bell more difficult to clean and easily damaging the burner; Furthermore, great care is required that all glasses are made exactly the same and that the edge of the glass is even, because otherwise when the radiator is put back on the latter will be crooked and this will prevent the flame from burning evenly. Furthermore, if the radiator is completely removed (for cleaning purposes) there is a risk that parts of it will be broken or damaged. To avoid these disadvantages, the radiator is simply placed on the glass bell and can be ^{rotated about a vertical pin e 1} , which forms the extension of the arm e . As can be seen from FIG. 2, the hinge piece d fastened to the radiator has on the inner side a slot or a groove which serves to receive a guide strip protruding inward ^{from the pin e 1.} As can be seen from Fig. 1, this strip is less, long than the hinge (ie it does not reach from the lower end of the same not all the way up) and prevents in the normal position, Fig. 1, the rotation of the heating element about the pin. In order to be able to turn the radiator on its side, it must first be lifted until the hinge piece d is over the upper edge of the bar. If you then turn the radiator around the pin e ¹ , the lower edge of the hinge piece d rests on the upper edge of the guide bar, which thus supports the radiator. The bell jar b remains and can be easily cleaned. To put the radiator back on the bell jar afterwards, you must first turn it back until the longitudinal groove of the hinge piece comes to stand ^{exactly over the guide strip of pin e 1.}

This ensures that the radiator is exactly in the same position as the bell jar must come, which the same took before taking off. In this position the radiator has the correct position to the burner and presses evenly with its own weight on the edge of the bell jar, whereby the necessary seal is achieved. ·

The bar on the pen e ^l thus serves once

als'guide and the other time as a base for the radiator.

As can be seen from FIGS. ¹ and 2, the upper bent part of the arm e also carries the holder / for the reflector / 1. The gas inlet can also take place at the top at e ² or at the bottom at e ³ . In one case the lamp is set up as a hanging lamp and in the other case as a floor lamp.

II. Ignition device.

Lamps that can be closed from above through the chimney or from below through a lockable Opening in the bell jar have the disadvantage that they close easily a lot of gas can get into the bell, causing an explosion when ignited.

In order to make ignition easier, safe and safe, the gas supply pipe below the burner and the bell jar b is surrounded by a cylindrical sleeve g ² , which forms an annular ignition space around the gas pipe verschliefsbare Seitenöffhung g ³ and connected to the interior of the bell jar through an upper opening · g ^e and g to the ignition port ³ is in the gas line, a small reduction valve g ¹ is turned on. the valve housing has a lateral through bore g · ^5, which in the in Fig. 1 shown normal position of the valve is closed, while the access of the gas to the burner is open.

But when you turn the tap means of the peculiar shaped lever · g ^4, which at the same time as the ignition port for Verschlufsklappe g ³ and serves as a guide for the pilot flame, it is a great measure the blocked Gaszuflufs by the burner, while the Ausflufs- of the gas through the opening g ^{s is opened} after the ignition chamber and the latter is simultaneously accessible from the outside through opening g ³ , as shown in FIG.

The lamp can remain in this position for a long time without the danger of exploding when it is lit; because only a small amount of gas collects in the bell jar, since most of the gas flowing in can escape through the side opening g ⁵ of the tap and the ignition opening g ³ .

The gas flowing out through the ignition opening is now ignited by means of a pilot flame, the specially designed arched flap preventing the flame from touching the bell jar and the combustion propagating to the gas flowing out of the burner. The flap g ^{l is then} closed and, as a result, the cock g ^{1 is} rotated back into its original position, FIG. 1. The lever g * thus serves at the same time to turn the tap, to open the ignition hole and to protect the bell jar.

Claims (2)

Patent Claims: ι. A regenerative gas lamp, characterized in that an arm e simultaneously serving as a gas supply tube and lamp holder carries the burner together with the ignition device and glass bell at the lower end, while the upper end forms a peculiar hinge around which the regenerative or heating element can be rotated horizontally The hinge pin e ¹ formed on the arm e has a longitudinal bar which fits into a corresponding groove of the hinge piece d attached to the radiator, and said longitudinal bar is used one time only to guide the radiator and the other time only to support it. 2. On the lamp characterized in claim 1, the device of the ignition device in such a way that it consists of a reduction valve g 1 connected to the gas line with a side opening g ⁵ , a sleeve g · ² enclosing the ignition chamber and a peculiar ignition flap g ⁱ , the ignition chamber being provided with the inside of the bell jar b through an upper opening g ^ß and with the atmosphere through a side opening g ³ located below the tap, and the ignition flap at the same time as a lever for turning the tap and protecting the bell jar against the pilot flame serves. For this purpose ι sheet of drawings.
