lighter of this class wherein the manipulation thereof is simplified and facilitatedand the device is rendered more convenient for use, it being necessary to simply tip or rock the.

heating wire carrier relatively to the base, while the carrier is mounted thereon, in order to supply electric heating current to the heating wire, after which the carrier contain ng the heated wire may be detached from the base and used.

Electric lighters are known which comprise a carrier for the heating wire removably mounted in a contact casing and adapted to.

be switched into the circuit by bein moved in this casing. In cigar lighters of this type and of known construction, which are operated by one hand, the carrier of the heating wire must be displaced in axial direction in opposi+ tion to the action of a spring to switch the so same into the circuit. As soon as the pres sure ceases, the carrier of the heating wire is automatically cut out so that it can be removed from the casing and used for llghting a cigar.

'Electric cigar lighters of this type possess all the inconvenience that, if any erson should accidentally press on the cigar ighter the circuit might be closed so that the garment of the person is damaged or the cigar lighter 40 destroyed.

According to the particular form ofthe nvention shown, the holder of the heating wire carrier is elastically mounted in the contact casing opposite the current supply contacts so that it has to be tipped, turned or placed on edge in tl'iecontact casing for closing the circuit.

Owing to the tipping, turning or placing on edge of the removable heating w re carrier lVhenreleased, the holder returns instantaneously into the cutout positlon.

the danger is considerably reduced that, by

accidental depression of the carrier, the circuit be closed. Y

The carrierfor the heating wire is insertedinto the contactcasing perpendicularly to the central line ofthe casing and the carrier can consequently be made flatter than this Won! ('1 be otherwise the case, and the. heating wires are visible fromthe outside.

In the drawing aform of construction-of the invention isshown by way of example Fig. 1 shows the cigar lighter in the posiition of rest, the casing being, shown inseclOIl.

Fig. 2 shows the cigar lighter in the switched-in position.

Fig." 3 shows in plan View the casingythe carrier of the heating wire being removed.

A is a carrier in which a heating wire B, adapted to be heated in consequence of its resistance to the flow of an electric current therethrough, is located. The carrier A has on its bottom'platea button-shaped circumferentially grooved extension I) of metal which is to be inserted into the 0 en end of a slot formed in a frame-like hol er, H of the contact casing Ci whidh forms art of the stationary base of the lighter. This holder H is yieldably mounted by means of a pivot pin L which. 1s suitably supported within the casing" and connected to the holder H toward one of its ends, it extending behind andperpendicularly to the length of the slot therein, and is acted on by a spring M. The spring. M bearsat the one end onto the slottedholder H and at the other end onto the bottom plate F of the casing. The contact spring E is fixed to the slotted holder H. Between the bottom plate F andcasing 0 an insulating plate 0 of cardboard is inserted, so that one of the branches of the circuit is formed by the casing, and the other branch of the circuit, which includes the slotted holder H and contact spring E, is insulated from the casing, and the front wall of thecasing is formed with a slot F3 whichextends parallelwith and is larger than the slot in the holder H so that the extension Don the carrier A may extend through the slotF' while engaged with the holder, without making one end 0 the heatin wire B, the other end of said heating wire ing connected by the conductor a, to the outer body portion of the carrier A; f

As shown in Fig. 3 the contact plug 1' is electrically connected to a contact coating N which is mounted in the casing insulated from the same and opposite the contact spring E The second contact plug I- is connected to the mass of the casin The operation is as follows: In ig. 1 the contactspring E is in the position of rest s accd from the contact coating N.- When t ecarrier A of the heating wire is tipped, asshown in Fig. 2, the blade spring E comes into touch with the contact coating N, since the holder'H to which it is fixed, is drawn forwardly by the button-shaped extension I) i engaging it, and at the same time, an edge of the body of the carrier A is in electrical contact with the face ofthe casing C, so that current flows through the heating spiral B between one side of the electric circuit which is connected/to the casing G, and the other side of said circuit which is connected to the spring E insulated from the casing. As soon as the heating wire has been sufficientlyheated, the carrier A is pulled out if the slottedv holder H and used for lighting a cigar.

After use the carrier A is re-inserted into stationary casing respect to the base into a re atively tipped position where it will cause engagement of said contacts and closing of the electric circuit throu h the heatin resistance.

An e ectric ci ar ighter comprising a movably mounted on the casing and havin aving electric contacts thereon, and a heating resistance carrier re- I electric contacts to cooperate owxth those on the'casin'g, the heating resistance having an' electric circuit which includes said contacts, said carrier being movable into a tip "position with res v t to the casin an thereb o erative to c ose the electric circuit throng 1 t e heating resistance, and means operative to automatically return said carrier to a normal osition, when released after being tippe to thereby open thecircuit throng the heating resistance. i
