ELECTRIC GAS LIGHTER Filed Aug. 30, 1929 In" (ll/(III,

Patented Feb. 21, 1933 LUDWIG zWrLLINe, or wALLDonF 1N HESSEN, GERMANY ELECTRIC Gas LIGHTER Application med August ao, 1929, semi No. 399,520, and' in Germany september 12', 192s.

Electric gas lighters operating with a Weak current and having a dry battery contained in a casing have the disadvantage, that the battery becomes stuck in the casing when an incrustation is formed. As with the constructions now in use it is not possible to eject the used-u battery, since they are partly or entirely clbsed on one side, the gas lighter becomes useless. This disadvantage is overcome by the present invention by the casing being of the same internal diameter throughout, such that a battery may be pushed right through, so that a used-up battery which has become stuck in the casing through an incrustation being formed may be removed by a blow against the zinc end, without the casing being damaged.

The invention is illustrated in the drawing, in which Fig. 1 is a side elevation lighter,

Fig. 2 a section on line A-B of Fig. 1 with the battery in a side elevation,

Fig. 3 a view from above of the gas lighter,

F ig. 4 a section through a detail to an enlar ed scale and Bgig. 5 a section on line C*D of Fig. 4.

A metal casing 1 of uniform diameter is provided at the two ends with the threads 2, 3. The latter serve the purpose of screwing on the lighter head 4 and the bottom cap 5. Between the two is located the battery 6 consisting of 2 dry cells, the Zinc end of one cell resting on the conta-ct pin 7 which is fixed in a fibre disc 8 and is positioned opposite a resilient tongue 9, which effects the connecting up of the lighting wire.

The lighter head 4 referred t0 above hasI a central contact pin 10 by which the two fibre discs 11, 12 and the lighting wire holder 13 clamped between them are held together. The latter consists of two limbs bent over at an angle, and are guided in the fibre disc 12. The ends are connected together at one end by the lighting wire 14. The lighting wire holder 13 in the lighter head 4 and the fibre disc 8 in the bottom cap 5 are fixed by the Hat depressions 15, one of which rests in the lighter head 4 against the outer contact wire 13, whereby a good conductive conof the electric gas nection is established between the lighter head 4 and the lighting wire holder 13.

On the tongue 9 being pressed aga-inst the Contact pin 7 the current flows from the carbon pole of the battery 6, by means of the contact pin 10 through the lighting wire holder 13, the Vlighting helix 14 tothe lighter head 4,'the metal casing 1, the bottom cai 5 and passes' through the contact in 7 to the z'inc bottom ofthe battery 6. 'llhrough the circuit thus closed the lightinghelix 14 is caused to become incandescent. V

Havinor now particularly described and ascertained5 the nat-ure of my said invention and in what manner the same is to be performed, I declare that what I claim is: n

1. An electric gas lighter for operating with' a weak current, comprising a metal casing, a battery enclosed in the metal casing, a lighting wire, a lighting wire holder, means for carrying the lighting wire holder at the upper end of the metal casing,a closing cap at the lower end of the casing adapted to press the battery against ,the lighting wire holder, a fibre insulating disc in the closing cap, a contact pin mounted in the fibre insulating disc and contacting with the zinc bottom' of the battery and a resilient contact tongue in conductive connection with the closing cap adapted to be pressed into engagement with the Contact pin'. I A

2. An `electric gas lighter as claimed in claim 1,-havingv an annular intermediate disc between the contact tongue and the fibre disc.

3. An electric gas lighter for operating with a weak current, comprising a metal casing, a battery enclosed in the metal casing, a lighting wire, two fibre discs, a central contact bolt passing through the centres of the discs and adapted to hold them together, two angularly shaped electrodes resting in holes in the upper fibre disc adapted to form a lighting wire holder, means for carrying the lighting wire holder at the upper end of the metal casing, means at the lower end of the casing for pressing the battery against the lighting wire holder and switching means for completing the electrical circuit.

4. An electric gas lighter for operatin with a weak current, comprising a metal cassie ing, a battery enclosed in the metal casing, a lighting wire, two ibre discs, of which the lower disc is larger than the upper one, a central contact bolt passing through the centres of the discs and adapted to hold them together, two angularly shaped electrodes resting iny holes in the upper fibre disc adapted to form a lighting wire'holder, a'cap attached to the upper end of the metal easing and adapted to carry the lighting wire holden the lower ibregdisc being adapted to serve i as a vstop member when the lighting wire holder is inserted in the cap, means -at the lower endvoi the casing for pressing the battery against the lighting wire holder and switching means for completing the electrical circuit.

5. An electricy gas lighter for operating with a weak current, comprising a metal casing, a battery enclosedV in the metal casing, a lightingwire, two bre discs of which the lower disc is larger than the upper one, a centralcontact bolt passing through the centresof the discs and adapted tohold them together, two angularly sha ed-l electrodes resting in holes in the upper re disc, adapted to form a lighting wire holder, a cap attached to the upper endofthe metal casing and adapted to carry the lighting wire holder,

s the lower fibre disc being adapted to serve as d'1" a stop member when the lighting wire holder is inserted in the cap, a closing cap at the lower end of the'casing adapted to press the battery against the lighting wire holder, a

libre insulating disc in the closing cap a contact pin mounted in the ibre insulating disc and contacting with the zinc bottom of the battery, a resilient contact tongue in conductive 'connection with the closing cap adapted to be pressed into engagement with the contact pin and an annular intermediate disc between the contact tongue and the bre disc. 1

6. An electric gas lighter as claimed in y claim 5, in which the caps attached to the metal casing have depressions adapted to hold the fibre discs. t
