ELECTRIC CANDLE.
Application filed December. 16, 1922. Serial No. 607,297.
To all whom it may coowern Be it known that I, Tm'looona S'riicKEL- BERGER, a citizen of the Swiss Confederation, residing at Montmirail, Switzerland, have invented certain new and useful Improvements in Electric Candles (for which have filed an a plication for patent in Switzerland on tlie 11th of September, 1922), of which the following is a specification.
This invention relates to an electric candlewhich can be used for any purposes, such as rooms, bicycles or the like, in analogy with the battery lamps known er se. The object of the invention differs rom the battery lamps in so far that no special protecting casing is necessary, where v by however the pleasant appearance, the applicability and the illuminating power are not impaired.
The characteristic feature of the invention consists in that a closed cylindrical tube, which serves as a waterproof electrically insulating protecting sleeve, encloses absolutely airtightly a galvanic battery and carries at one of its ends -an electric glow lamp bulb which is mounted in such a manner that without a casing and consequently without the aid of the contact device of acasing, theelectric circuit is directly closed and interrupted by the glowlamp bulb itself in consequence of a rotation of the same in corresponding direction. The glow lamp bulb is protected by means of a" transparent sleeve with reflector, this sleeve being mounted upon the candle. I
In the accompanying drawing the object of the invention. is shown in a form of construction by way of example, wherein:
Fig. 1 is a side elevation.
Fig. 2 a vertical section.
Fig. 3 shows the protecting sleeve with reflector seen from the side where it is slit.
Fig. 4 shows a diagram of connections.
With reference to the drawing, l designates the cylindrical tube which is preferably made from electrically insulating waterproof white and opaque material, for instance celluloid. In the tube 1 three dry cells 2 are super osed and connected in series (Fig. l) he negative pole of the one element is always confnected with the positive pole of the other element by the wire 3.
The number, shape, size and arrangement of the elements 2 can be difi'erent from those shown on the drawing as they depend on the dimensions of the candle.
Between the sides of the elements which face one another a disk'4 of celluloid is ar-. ranged and the free space between two adjacent elements is filled with an insulating mass, for instance cotton wool, spun glass or the like. The tube 1 is closed at the lower end by a cover 5 and at the upper end b a cover 6. Covers 5 and 6 are preferably made both of the same material as the tube 1. The end of tube 1 closed by the cover 5' is made tight by a filling mass 7 and the other end y a mass 8. The filling'mass 7 or 8 consists of a waterproof electrically insulating material, for instance resin or the like.-
In the filling 8 the Edison screw 9 is em-.
bedded into which the electric low lamp bulb 10 is screwed. The one end of the insulated wire 19 is connected with the Edison screw 9. If. the inner contact of the glow lamp bulb comes in contact with the carbon electrode 11 or with the positive pole of the battery chain the circuit is closed and the incandescent lamp burns as the screw 9, owing to the connection by wire 19,
represents the negative pole of the battery candle when being'Bplaced upon a table or V similar surface. dis lacement ,of the Y handle 13 the glow lamp ulb 10 is rotated and brought into or out of the contact position according to the direction in which it is moved. Upon the up er end of tube 1' the protecting sleeve 14 or the glow lamp bulb 10 is mounted. This protecting sleeve bulb 10. This disk 4 14 is preferably made of elastic transparent material, for instance film, and it has a longitudinal slit 15. Owing to'this slit 15 the protecting sleeve exerts upon the candle an elastic clamping action and a pressure. The handle 13 serves as support for the pro tecting sleeve 14 as regards displacement in longitudinal direction and when bein turned it efi'ects not only the rotation o the glow lamp bulb 10 but also of the protecting sleeve 14. Slit 15 has approximately at its middle an enlargement 16 which is designed to receive the handle 13. Inthc protecting sleeve 14 a reflector 17 is arranged which extends only over one half of the circun'iference of the rotecting sleeve. The inwardly directed re ector consists of a tin foil, a mercury foil, an aluminium foil or of any convenient material and it is embedded in the mass of the protecting sleeve or mounted upon the outer wall of the same. If the candle has to be used without reflector the protecting sleeve is merely turned upside down so that the half of the sleeve fitted with the reflector is in contact with the cylindrical tube 1.
The hand lever 13 of the annular disk 12 projects through the enlargement 16 of slit 15. If the protecting sleeve 14 is rotated by hand the hand lever 13 is drawn along and consequently the glow lamp bulb 10 is rotated so that it is lighted or extinguished.
Under normal conditions it is impossible that the glow lamp bulb is accident-ally or automatically rotated as the rotation of the protecting sleeve 14, in consequence of its elastic action, requires a certain expense of power.
Below the annular disk 12 a packing ring 18 is further arranged upon the glow lamp bulb or upon the socket of the same, said mcking ring 18 consisting of leather or rubber and being supported by the annular disk 12. It the glow lamp bulb 10 is brought into contact position this packing ring 18 is compressed and closes airtightly the'hole through which the screw part of the glow lamp bulb extends. Consequently the candle can be used also under water without any dama e of the elements. The packing ring 18 will be used only it the protecting sleeve of the candle, which is the cylindrical tube 1, is
itself insulating and waterproof.
The costs of manufacturing the object of the invention are very low and certainly not higher than that of the batteries of the well known pocket lamps. If the battery elements 2 are worn out they are thrown away together with the cylinder 1, the glow lamp bulb 10 with the annular disks '12, 18, the hand lever 13 and the protecting sleeve 14 being used in connection with a new battery.
