This invention relates to electric cigar lighters of the automatic so-call'e'dV pop-out 'type -generally used vin motor cars, although equally adapted to hmerand office use;
Lighters of this type usually havev an igniting unit which carries a heater coil and is movably supported-in a socketmember from Whichii-t *can be removed for use in lighting a oigan-'cigarette or the like. It-is normally held -in open-circuit, non-heatingv position in -the' socketmember. When Wanted for use it is movedinto closed-Loir'- cutheating position by a pushing'action which slides the unitdeeper into the socketA member, whereby electric contact vis made through the heater coil, and.` in which position theunit isheld until the coil rea-ches the desired*-temperature'. Thereupon a thermostat causesrelease of the-unit which is then returned-byspring' pressure to1 its normal open-circuit position in the socket member from which a usercan extract it -for lighting purposes.
Duringnormal-periods lof non-use the' igniting unit is carried in the socketv member in its outer, open-circuit position vand is only advanced into the socket member whenvit is desired-to raise the heater coil to the desired temperature for-use1 Such movement is eiected-by a straight pushing action applied to a knob -or-the lik'eon theunit which projects outwardly beyond the supporting socket member.
A great disadvantage of such devices has-been the relative ease ofv'inadvertent-ly pressing'l the igniting unit into closed-circuit heating-position when it is lnot intended to dosc; Thisfisdone' sometimes by a car occupant resting ari-elbow on a lighterinstalled incr nearthe armfofI a back seat in a motor car, or by a person getting `inior out of a car,- or by a folding -front seat striking an igniterinstalled in .the'front compartment of a car.
Anobject of this invention is to provide -an improved cigar-lighter constructed-and arranged to prevent unintentional movement ,of` the igniting unit into? operative heating position..-
A feature of theinvention is the provisioniin an velectric cigarY lighter of 4a member.arranged to block movement of .the ignitingunit into1op1 erative heating. position .in .thesupporting socket member as the result of 'pressureappliecltothe endd face of the associated' handle or: knob, :toigether with a releasing device which canbezop` erated only by intentional actionA on` the .part of a user; A vstraight pushing operation will not alone advance the. unit into lthe socket member soithat'such accidental movement Aasnabove de.- scribed cannot occur.
2. A furtherfeature is the provision of `a lock release in a position-to be *gripped 'by the-fingers of a userand operated -to thereby--causetlielock l ing device to release-and free theunit for movement inwardly vto-operati-ve closed-'circuitposition.
This is accomplishedby so constructing and arranging the handle knob by which the ignitin'g unit is manipulated that pressure -appliedrto--the endface only' of vthe knob-will not bereffe'ctive to shift the unit into closed-circuit position.:Y Such movement can'onlyl be accomplished byJ applying Apressure rst to the outer rimof 1 the -knob and Vfirstmoving such lrim inwardly7x to `accomplis'h the releasing' action. Such anoperation normally requiresva user to yintentionally grip the movable rim in order to---operate the release.
A still further feature is the provision cfa control an-d operating member so constructed as to permit a -user to employv one hand -andsubstantially one movement tov-release the igniting unit and immediately pressvit into heating position.v
Other features and advantages will hereinafter appear.

Fig. v(-3 is a `View similarto: Figs. 1 and 2, on a re'ducedffscale, showngrthe igniting unit pushed inwardly ltooperative `heating position in: the supporting. socket member.
The. illustrated embodiment of the invention is shown in connection with a plug type. automatic cigarlighter such.r as is .especially adapted for-use in; motor cars. .As illustrated, it includes a cylindrical base or sockety member' 1l comprising'ya sleeve l2 forming a deep socket i3 adapted -to'bev mounted'inr a suitable opening I5 in ther-instrument panel I4, Vfor example, ofa motor car. The outer'end of the socket member' has-a flangenl engaging the panel.`
The socket member is=secured -in-:placeby a fri' sleeve Il which may be formed at the bottom with a threaded aperture i8 threaded on a sleeve I9 secured to the bottom of the sleeve i2. Ground Contact by the socket member is made both directly to the grounded panel i4 by engagement of the flange IB therewith, or through the threaded connection I9, It and yoke il' to the instrument panel which is engaged directly by the ends of the yoke.
Contact fingers 2l which are insulated from the socket member are supported in the lower end thereof and electrically connected to a conductor 22 leading to car battery, or similar source of potential.
As illustrated, the removable igniting unit 23 comprises a plunger section 24 on the end of which is carried a holder 25 for the heater coil (not shown). The holder 25 has an annular ridge 25a for engagement with resilient contact portions 25h formed in the wall of the socket member to insure a good ground contact when the unit is in closed-circuit heating position.
A handle knob 25 for manipulating the igniter unit projects outwardly in position to be readily grasped by a user. The knob includes a stem 2'! threaded at its lower end into a plug 28 which is in turn threaded to the upper end of the plunger section 24. The stem 2l has a knob head 29 forming an end face 35 on the extreme outer end oi the knob.
The upper end 24a` of the plunger section 2t is of reduced diameter and a sleeve l slidably surrounds the reduced end. A coil spring is interposed between a iange 33 on the lower end of the sleeve and a radial flange te on the plug J. By this arrangement the igniting unit is normally yieldingly pressed by the spring S2 so as to hold the igniting unit in the open-circuit position illustrated in Figs. i and 2. By pushing the igniting unit inwardly in the socket member i2,
the spring contacts 2l yieldingly engage and hold a rounded contact surface on the heater coil holder 25, as shown in Fig. 6, whereby a heating current passes through the heater coil and raises it to the desired temperature for use, at which time the yielding contact members 2i being formed of bimetallic strips move outwardly to disengage the contact surface 35 and release the ignting unit. When thus released, the
The means provided for preventing accidental movement of the igniting unit into the socket to closed-circuit heating position, as illustrated, comprises a latch member il mounted for radial sliding movement on the plug 2t. The latch member is mounted below a retaining element 42 and has a slot 43 receiving the stem 2l of the knob 25. A leaf spring 44 is secured to an inner flange 44a on the sliding latch 4I and engages the wall oi a circular recess 44h in the retaining element 42 to normally maintain the nose 45 of the latch in projecting position to engage the face of the radial ange Sla on the sleeve 3l. For this purpose the latch il extends through a slot 4l in the side of the retainer 42. It will be apparent that when in this position the latch 4l blocks any movement of the igniting unit into the socket member l2 and no accidental pressure applied to the end face 30 of the knob 25 can produce such movement.
Such movement can only be effected by interltional action on the part of a user. The illustrated mechanism for accomplishing this includes a sleeve 5l slidably mounted on the stem El of the knob 25 and formed with a recess 52 receiving the knob. As a result the outer edge 53 of the sleeve '5i forms, in effect, the rim of the knob for manipulating he igniting unit. A helical spring 54 in a recess 55 in the lower end of the sleeve is compressed between the bottom of the recess and a spring seat 56 formed on the top of the latch retainer 42.
The lower end of the sleeve is formed with a recess 5l for receiving the latch retainer 42 and the lower edge of the sleeve surrounding the recess is formed with a beveled cam face 55 adapted to engage the beveled cam face 58 adapted to engage the beveled upper face on the nose 45 oi the latch member 4l, whereby inward movement of the sleeve 5l relative to the stem 21 causes the engaging cam faces 513, to to shift the latch member 5| inwardly to the position shown in Fig. 2, thus freeing the igniting unit for movement into the socket member to closedcircuit, heating position as shown in Fig. 6. In this position heating current flows through the heater coil. When the latter has been raised to the desired temperature the bimetallic spring contacts 2| release the igniting unit, permitting the spring 32 to snap it back into normal opencircuit position shown in Fig. l, from which position it can be readily removed from the socket member for lighting purposes and then returned to the open-circuit non-heating position shown in Fig. l. In this latter position the latch il again deiinitely blocks inward movement of the igniting element and no amount of pressure applied to the end face 35 of the knob either when returning it to the socket or at any other time will cause it to move into closed-circuit heating positon. Such latter movement can only be obtained by intentionally applying pressure to the rim of the knob formed by the sleeve 5l and sliding it inwardly to produce the unlatching operation above described, whereupon the igniting unit is released for inward movement to closed-circuit heating position.
