UNITED STATES STORM LANTERN BURNER Briino Nier, Beierfeld in Sachsen, Germany Application July 14, 1936, Serial No. 90,572 T In Germany August 12, 1935 6 Olaims.

The present invention relates to storm lanterns and more specifically to improvements of the burner plate construction including .the mounting thereof in lanterns of this general type.

In many storm lanterns heretofore known the burner or flame plate was secured to the Wick tube and the wick tube together with the burner plate projected from the interior of the. lower portion of the lamp. In such constructions the wick tube together with the burner plate was often displaced out of its central position during the manufacture ofthe lamp or during use. and thus the wick tube no longer'retained its correct central position in the burner cap. Such displacement or" the flame plate caused the lantern to burn inefiiciently.

An object of the present invention is to avoid such defects byenlarging the burner plate and constructing it in such manner that it is constantly in contact with another part of the burner and thus permanently held in the correct position.

For this purpose the burner or flame plate is dished and preferably formed in the shape of a bowl. However, in other embodiments of the invention it is suiflcient for the flame plate to be constructed as a simple disc with or without an upturned edge. The lower part of the burner, the upper part of the burner or both parts can be employed as a. guide with which the burner or flame plate remains in contact in the finished lantern. i

When the flame plate is in the form of a bowl and is held by the upper or lower part of the burner, it need not be rigidly connected with the wick tube but an air gap can be provided between Also, material which is a poor conductor of heat can be interposed between the flame plate and'the wick tube as described in my copendingapplication Serial No. 90,573, filed July. 14, 1936.

In addition, the flame plate can be provided with apertures which afford a materially improved supply of air to the flame which. results in a considerably improved burning of the flame.

The present invention not only ensures an absolutely reliable positioning of the wick tube and of the flame plate as already mentioned, but as the wick tube is reliably held in the central position it is ensured that the lantern will burn well in all circumstances. The construction of the flame plate makes it possible to obtain a better supply of air to theflame. The resultant heat can be conducted away from the wick tube in a reliablemanner by way of the flame plate to constructional elements of thelantern which are either not connected with the wick tube or have so slight a connection therewith that the transfer of the heat from them back to the wick tube does not takeplace. In this way, it is ensured that the storm lantern provided with the new burner burns Well even in regions where the outer temperature is high. It must be emphasized that this advantage is obtained by simple means with the use of ordinary materials and without appreciable increase in the cost of manufacture.

Certain embodiments of the invention are illustrated diagrammatically in, the accompanying drawings, in which:

'Fig. 10 is a sectional view of a further embodiment of the invention, Fig. 11 is a section at right angles to Fig-10 and Fig. 12 is a sectional view along the line A- of Fig. 10. I

The burner or flame plate as a whole is indicated by a in the embodiment shown inFigs. 1 to 3 and it is in the form of an inverted bowl which is secured to the wick tube e by flanges provided on the latter. The connection however could be effected in any other convenient manner. The lower edge I) of the burner plate a fits into the base or lower part c of the burner in such a flame plate, the wick tube e and the wick itself are secured centrally in a non-displaceable and reliable manner.

In addition tothe usual apertures in the burner plate, openings h and i are also provided as shown in Fig. 3. These openings are of considerable importance for the proper burning of the lantern, because they improve the supplyiof air to the flame and thus assist materially in the proper burning of the lantern.

It is also clearly apparent that the heat generated is transferred with certainty from the wick tube e to the burner cap g and thus does not affect the flame detrimentally.

In the embodiment shown in Figs. 4 to 6 the inverted bowl-shaped burner or flame plate a is separate from the wick tube e and an air gap 1 is left between it and the wick tube. In this embodiment the burner plate surrounds the wick tube on all sides. The wick tube is reliably pro.

tected against displacement and the correct central position of the wick tube with respect to the 7 burner cap is ensured.

The embodiment illustrated in Figs. 7 -to 9 shows a burner or flame plate a which is not connected with the lower part'of the burner and has only a flange m which comes into contact with the inner wall of the burner cap g. The flame plate is thus held in the correct position by the burner cap. The burner cap itself is always positioned centrally of the burner and the above described contact adequately ensures the central positio n of the wick'tube even if there should be distortion during manufacture or during conveyance which may result in a displacement fromthe central position of the flame plate. 'The flange m also serves for the reliable transfer from the wick tube to the burner capof the heat arising at the burner plate. r p

If the burner plate is rigidly connected with the wick tube, then the flange m can'be dispensed with. In this case it is sufficient for the burner plate itself to be in contact with the burner cap as this adequately ensures the desired centering of the wick tube and the desired conveyanceof heat away from the wick tube.

In the embodiment illustrated in Figsi'l' to 9 the apertures is shown in Fig. 3 are dispensed with; 'It has been found that the openings h and i are best adapted to supply the necessary airto the burning flame without material detriment'to the behaviour of the lantern in spite of theefl 'ect of shaking and the eflect of storms. Moreover, the omission of the apertures 7c enables the eddies otherwise occurring at these apertureswhen the lantern is exposed to shaking or to a storm to be avoided and this also constitutes a material improvement over storm lanterns of the'prior art.

In the embodiment shown in Figs. 10 to 12 the inverted bowl-shaped burner plate a" is extended down to the wall of the oil reservoir q. The burner cap g" is carried on a shoulder of the burner plate a". Theslot'n in the burner cap must be held 'in the correct position with reference to the aperture 0 of the wick tube and this is effected by interengaging notches p and in? as shown in Fig. 12 in the" burner cap and burner plate. In this case the lower part n of the burner plate constitutes the lower part of the burner cap.

This construction of'the burner plate aliords the advantage that the heat which is produced at the burner plate is conveyed directly to the oil reservoir, i. e. is transferred to the component parts of considerable surface area and the heat thus is dissipated in thebest possible manner. I

It will be apparent, therefore, that the dirnensioning and-shaping of theburner plate in ac: cordance with the invention ensures the requisite central position of wick tube and burner in a simple manner and improves the operation of the storm lantern while the provision of the large openings in the burner plate. and the elimination of the numerous apertures otherwise employed avoids the formation of undesirable eddies and gives a very favorable supply of air to the flame.
