QUANDT LIGHTER WITH ELECTRIC IGNITION 2 Sheets-Sheet 2 Filed NOV. 17. 1955 1 76/15 4 1am! t i a B rd/WM United States Patent LIGHTER wrrn ELECTRIC IGNITION Hans Hubert Quandt, Karlsruhe, Germany, assignor of one-half to Rudolf Mohr, Karlsruhe, Germany Application November 17, 1955, Serial No. 547,574

Claims priority, application Germany May 23, 1952 11 Claims. (Cl. 317-91) The present invention relates to electrically ignited cigarette lighters of the kind in which a liquid or gaseous fuel is ignited by a glowing filament which is energized by a battery or other source of electric current.

Where a liquid fuel, such as benzine, is used it is fed to a wick which is ignited by the filament. gas fuel, such as butane, is used, it is stored under pressure in a container and is discharged through a nozzle when the lighter is to be used, the discharging gas being ignited by the filament.

From one aspect the present invention consists in a lighter having electric ignition of the fuel by means of a filament mounted on a carrier slidable by an actuator from a normal position where the filament is de-energized to an igniting position where the filament is heated by current passing therethrough to ignite the fuel, wherein the burner, which may be a fuel wick or nozzle, and the filament carrier are positioned in a space surrounded by walls at the top of the lighter casing, said space being normally covered at the top by a movable cover and fuel sealing device which is moved to an open position to expose the wick or discharge the gas by or upon the movement of the actuator to move the filament towards the igniting position, and wherein one or more of said walls is/are provided with one or more apertures for the admission of air to said space to assist the fuel to burn.

The invention also consists in a lighter having electric ignition of the fuel by means of a filament mounted on a carrier slidable by an actuator against the action of a spring from a normal position where the filament is de-energized to an igniting position where the filament is heated by current passing therethrough to ignite the fuel, wherein the fuel wick or nozzle and the filament carrier are arranged in a hollow head of elongated shape (in plan) adapted to be mounted on a casing which accommodates an electric battery, and the fuel container, the wick or nozzle being positioned adjacent one end of the space within the head and the filament carrier being slidable along guides longitudinally within the head, and wherein the top of the head is provided with a movable cover which is moved to expose the wick or nozzle by or upon the movement of the actuator to move the filament towards the igniting position, the wall of the head at the end adjacent the wick or nozzle being provided with one or more apertures for the admission of air to the space within the head to assist the fuel to burn.

The invention also consists in a lighter having electric ignition of the fuel by means of a filament mounted on a carrier slidable by an actuator against the action of a spring from a normal position where the filament is deenergized to an igniting position Where the filament is heated by current passing therethrough to ignite the fuel, wherein the fuel wick or nozzle and the filament carrier are arranged in a hollow head of elongated shape (in plan) adapted to be mounted on a casing which accommodates an electric battery and the fuel container, the wick or nozzle being positioned adjacent one end When a iil of the space within the head and the filament carrier being slidable along guides longitudinally within the head, and wherein the top of the head is provided with a movable cover which is moved to expose the wick or nozzle by or upon the movement of the actuator to move the filament towards the igniting position, the wall of the head at the end adjacent the wick or nozzle being provided with one or more apertures for the admission of air to the space within the head to assist the fuel to burn.

The invention further consists in a lighter having electric ignition of the fuel by means of a filament mounted on a carrier slidable by an actuator from a normal position where the filament is de-energized to an igniting position where the filament is heated by current passing therethrough to ignite the fuel, wherein the fuel wick or nozzle and the filament carrier are surrounded by walls forming part of the lighter casing, one or more of which walls is/ are provided with one or more apertures adjacent the fuel wick or nozzle for the admission of air to the burning fuel, and wherein the actuator is slidable on the outside of a side wall and is connected to actuate the filament carrier by a member movable in a slot in said side wall, the said slot being covered by the actuator when the carrier is in its normal position and being uncovered by the actuator when the carrier is advanced to the igniting position to provide an additional aperture for the admission of air to the burning fuel.

The invention also consists in a lighter having electric ignition of the fuel by means of a filament mounted on a carrier slidable by an actuator against the action of a spring from a normal position where the filament is deenergized to an igniting position where the filament is heated by current passing therethrough to ignite the fuel, wherein the fuel wick or nozzle and filament carrier are arranged in a hollow head adapted to be mounted on a casing which accommodates an electric battery and a fuel container, and the carrier is slidable along guides beneath a plate which, in conjunction with the walls of the head, encloses and protects the filament except when the latter is in the igniting position and the filament projects beyond the edge of the plate, the carrier being moved by the spring at all times, when the actuator is released, so that the filament lies beneath and is protected by the protective cover plate, and wherein one or more apertures are provided in the wall of the head adjacent the fuel wick or nozzle for the admission of air to the space surrounding the fuel wick or nozzle.

According to a feature of the invention, the movement of the filament towards the igniting position causes a fuel sealing device (a wick cover in the case of liquid fuel or a nozzle seal in the case of gas fuel) to move to an open position out of the path of movement of the filament and also completes the electric circuits through the filament as it reaches the igniting position. The said movement of the fuel sealing device moves a stop into the return path of the carrier so that the stop will prevent the carriers, when the actuator is released, from returning fully to its normal position but will retain it in an intermediate position where the electric circuit to the filament is open and Where the slot in which the actuator slides still remains partly uncovered. The stop may be moved out of the return path of the carrier by the closing of the fuel sealing device. This may be effected by manually moving the actuator to its initial position which moves the stop and causes the fuel sealing device to close; or the fuel sealing device may be manually closed thereby moving the stop to allow the carrier to return to its initial position and hold the fuel sealing device in its closed position.

According to a feature of the invention, the contact for completing the circuit to the filament is in the form of a leaf spring which is engaged by a contact part of the filament carrier as the latter is advanced, the leaf spring flexing to allow the filament carrier to be further advanced to the igniting position whilst still maintaining the contact.

The filament is preferably made of or coated with a catalytic material such as platinum, whereby the filament will be caused to glow more brightly, when it comes into contact with fuses of the lighter fuel, so as to facilitate the igniting of the fuel. The position of the fuel fumes in relation to the wick or nozzle may vary for various reasons, for example due to draughts or as the fuel becomes more expended. In order to ensure that the filament will, as far as possible, always move into a zone where fuei fumes are present, according to a feature of the invention, the filament is mounted on the movable carrier by which it is advanced towards the wick or nozzle in such a manner that it is inclined in the horizontal direction to the normal to the direction of movement of the filament carrier, and preferably also i suring that the filament will be moved into a fume zone so that the catalytic action will produce the required brightening of the filament to ignite the fuel.

From another aspect, therefore, the invention consists in an electrically ignited cigarette lighter of the kind referred to in which a catalytic igniter filament is movable towards and away from the wick or nozzle, the filament being inclined both with respect to the normal to its direction of movement and with respect to the axis of the wick or nozzle.

The lighter may also incorporate an electric torchlight. To this end a small electric lamp is incorporated in the lighter and a switch is provided so that this lamp can be energised from the same battery as energises the igniter filament.

Another feature of the invention consists in resiliently mounting the wick cap relative to the lighter cover so that when the lighter cover is closed the wick cap will be pressed resiliently over the wick holder to enclose the Wick and reduce evaporation.

A still further feature of the invention consists in detachably securing the container for liquid fuel to the underside of the head for example by a kind of bayonet joint, whereby the container can be readily detached from the head by turning, for example through an angle of 90. The fuel container may also be provided with an opening at its end remote from the head through which the container can be charged with fuel, said opening being closed by a closure screw the hand of which is such that, to remove the closure screw, it must be turned in a direction opposite to that in which the container has to be turned to detach it from the head.

Further features of the invention relate to construction of the lighter as will be more fully hereinafter described.

An embodiment of the invention will now be de scribed, by way of example, with reference to the accompanying drawings, in which:

Figure 1 shows a perspective View of a combined lighter and electric torch according to the invention;

Figure 2 shows a longitudinal section through the lighter with the cover closed;

Figure 3 shows a view of the top of the lighter, partly in longitudinal section, with the cover open;

Figure 4 shows a section along the line AA in Figure 2;

Figure 5 is an exploded view of the various com ponents of the lighter;

Figures 6, 7 and 8 show a side view, a plan view. and an end view respectively of the igniter carrier.

Referring to the drawings, the lighter comprises a head 1 which accommodates the lighter mechanism and has a liquid fuel tank 2 depending from its underside, the head 1 frictionally fitting into the top of a casing 3 into which the fuel tank 2 extends and which also accommodates an electric battery or non-spillable accumulator 4 for energizing the igniter and also the electric torch bulb 5.

The head I is formed as a die-casting of generally hollow boat-shaped form with a wick holder 6 adjacent one end, which end is formed with openings 7 to admit air to the wick. The openings 7 are preferably formed as slots extending around the end and sides of the head adjacent the wick holder 6. The head is formed with a slot 8 extending horizontally along one side thereof into which fits the sliding actuating member 9 which is retained in position by the nut 10 screwed on to a projection 11 extending inwardly thereof. The projection 11 is connected by a spring 12 to the transverse bridge 13 of the head casting 1 so that the actuating member 8 will normally be pulled towards the right as shown in Figures 1, 2 and 4.

The top of the head casting 1 is closed by a cover comprising a fixed part 14 and a movable part 15 hinged to the fixed part by the pin 16. The parts 14 and 15 are also made as die-castings and have the shapes shown more clearly in Figure 5. The cover part 14 is held in position at the top of the head 1 by the screw 17 threaded into the socket 18 on the bridge-piece 13. A coil spring 19 surrounds the pin 16 and acts in a direction tending to move the cover part 15 to its open position as shown in Figure 3. To the underside of the cover part 15 is secured, by means of spigots 20 formed as part of the die-casting, a finger 21 and a leaf spring 22 to the end of which is secured the wick cap 23. The ends of the spigots 20 are rivetted over to secure the parts 21 and 22. The spring 22 resiliently urges the wick cap 23 over the wick holder 6 when the cover part 15 is in closed position as shown in Figure 2.

The cover part 14 is formed on its underside with two channels 24 forming a slide for the igniter carrier, the construction of which is more clearly shown in Figures 6, 7 and 8. The igniter carrier comprises a top metal plate 25 adapted to slide in the channels 24, to the underside of which plate are secured, by means of the rivet 26, two L-shaped metal members 27, 28 and two plates of insulating material 29 and 30. The mem ber 27 is in electrical contact with the plate 25 but the member 28 is insulated therefrom by the insulating plates 29 and 30, the hole in the member 28 through which the rivet 26 passes being of larger diameter than this rivet so that the rivet and member 28 do not electrically contact with one another. Across the front ends of the members 27 and 28 is secured the igniter filament 31., consisting of a coil of platinum wire, n such a manner that the direction of the filament is inclined both with respect to the plane of the plate 25 and to the normal to the direction of movement of the plate 25 in the channels 24. The member 27 is formed with a slot 32 which is adapted to engage with the projection 11 when the parts are assembled together so that movement of the actuating member 9 will move the igniter carrier in the channels 24 towards and away from the wick 33.

The finger21 on the underside of the movable cover part 15 is adapted to extend through an opening 34 in the part 14 and to be engaged with the plate 25 of the igniter carrier so that, when the igniter carrier is in its retracted position as shown in Figure 2, the finger 2i will be retained thereby so as to hold the movable cover part 15 in the closed position. When the actuating member 9 is advanced to move the igniter carrier towards the left (see Figure 3), the finger 21 is released and allows the spring 19 to turn the cover part 15 to the raised position.

When the actuating member 9 is rcieased the spring 12 will retract it and the igniter carrier towards the right until the plate engages with the finger 21. By lowering the cover part 15 the igniter carrier will be released and it and the igniting member 9 will move further towards the right under the action of the spring 12 to retain the cover part 15 in the closed position. Alternatively, by manually moving the actuating member 9 to its fully retracted position, the cover part 15 will be closed.

Beneath the bridge piece 13 of the head 1 is secured a member of insulating material which is moulded to the shape shown in Figure 5. The moulding 35 has a channel therebeneath into which are fitted in turn a metal contact 36, an insulating plate 37 and a metal contact 38, these three members and the moulding 35 being secured to the bridge 13 by the screw 39. The hole in the contact 36 is larger than the holes in the other members and actually fits around a spigot 40 on the underside of the moulding 35 so that the contact 36 is insulated from the contact 38 which latter is electrically connected to the metal of the head 1 and hence to the metal of the cover part 14, the plate 25 and the member 27. The battery terminals 41, 42 contact respectively with the contacts 36 and 38 when the head is fitted on the casing 3 with the battery 4 in position.

The contact 36 is provided with an upwardly extending contact finger 43 which acts as a leaf spring and is adapted to be engaged by the member 28 when the igniter carrier is advanced towards the wick, thereby completing the electric circuit through the filament 31 and causing the same to glow. The finger 43 flexes to allow the igniter carrier to be advanced to the igniting position, adjacent the wick 33 (Figures 3, 6 and 7) whilst maintaining the electric circuit. When the actuating member 9 is released and returns to its intermediate position with the plates 25 abutting against the finger 21, the member 28 will have moved away from the finger 43 to open the electric circuit through the filament 31.

The contact 36 also extends across the bottom end of an aperture in the socket portion 44 of the moulding 35, which socket is adapted to receive the torchlight bulb 5 which is held in position by the base contact of the lamp engaging with the contact 36 and the glass bulb fitting into an aperture 45 in the fixed cover part 14. Fitted around the internal walls of the head 1 at the end adjacent the lamp 5 is a U-shaped spring 46 having one end bent over and engaging in a slot 47 on the internal surface of the head 1 and its other end provided with a button 48 extending through a hole 49 in the wall of the head. The end of the spring which carries the button 48 has a backwardly bent contact leaf 5B which when the button 48 is depressed is adapted to engage the side contact of the lamp 5, part of the moulding surrounding the socket portion 44 being omitted to allow this contact to be made. Thus by depressing the button 48, the lamp 5 may be illuminated by current from the battery 4.

The fuel container 2 is detachably fitted to a spigot 51 east integrally with and depending from the underside of the head 1 directly beneath the wick holder 6. This spigot 51 has two diametrically opposed fingers 52 projecting therefrom which are adapted to pass through corresponding slots formed in an opening 53 in the top of the container 2 when the container is at right angles to its normal position relative to the head. After the fingers 52 have been inserted through the opening 53, the container 2 is turned through 90 to lock the two parts together. The underside of the top surface of the container 2, surrounding the opening 53, is made in the form of cam surfaces so that this turning movement will urge the container 2 upwards to compress a flexible sealing washer 54 between the top of the container and the underside of the head 1. The cam surfaces are pros? vided with stops to limit the extent of turning of the con tainer about the spigot 51.

The bottom of the fuel container is provided with an opening closed by a closure screw 55 which is so threaded that, to unscrew it from the container, it has to be turned in the same direction as is necessary to secure the container 2 to the Spigot 51 so that the action of unscrewing the closure screw 55 will not separate the container 2. from the spigot 51. The closure screw 55 holds a. U-shaped spring 56 in position with its limbs at opposite sides of the container 2 and bearing against the inside of the casing 3.

The wick 33 is folded about a strip metal member 57 and the wick assembly is inserted into the wick holder 6 by pushing it upwardly through the aperture in the spigot 51. The lugs 58 on the member 57 fit into recesses in the edge of the spigot 51 to locate the wick assembly in position, the free ends of the wick being inserted into the container 2 which is filled with cotton wool or other absorbent material 59. The member 57 keeps the wick 33 rigid and at the correct height for ignition by the filament.

The head 1 is provided with a downwardly depending guide portion 6%) at its end opposite to the fuel containcr, and a spring 61 may be fitted into this guide portion and be arranged to bear against the inside of the casing 3 to assist, in conjunction with the spring 56, in frietionally holding the head 1 and the casing 3 together.

The operation of the lighter is as follows: By moving the actuator 9 towards the left (Figures 1-4) the igniter carrier first releases the finger 21 and allows the cover part 15, under the action of the spring 19, to move to the open position shown in Figure 3. Further forward movement of the slider causes the metal member 28 of the igniter carrier to engage with the leaf spring con tact 43 to complete the circuit through the filament and cause it to glow. The flexible finger 43 allows the filament, whilst still glowing, to be further advanced towards the wick until it reaches the igniting position. By reason of the double inclination of the filament and the fact that it is glowing as it moves over a short distance adjacent the igniting position, the filament is moved through regions where the fuel-air mixture varies and a region can easily be found where the catalytic action of the fuel-air mixture on the platinum filament is the optimum for causing it to glow brightly and ignite the fuei, which then burns at the wick.

The actuator 9 is then released. The igniter carrier, however, does not immediately return, under the action of the spring 12 to its initial or normal position but is retained by the finger 21 in an intermediate position in which the contact 43 is disengaged from the member 28 so that the filament is de-energised. This partial return movement to the intermediate position is relatively short so that even with a sudden release of the actuator 9, there is no harmful impact on the hot filament, as would be the case if the spring 12 accelerated the igniter carrier right back to its initial or normal position whilst the filament was still hot. When in this intermediate position, as when in the normal position, the filament lies beneath the cover part 14, which acts as a protective cover plate therefor. The filament is only exposed when it is in or adjacent the igniting position and projects beyond the edge of the cover part 1-4.

When the actuator 9 is in the intermediate position, the slot 8 is partially uncovered and serves as an opening, additional to the openings 7, for the admission of air to the burning fuel.

The flame is extinguished when the cover part 15 is closed either by the finger, in which case the finger 21 is moved to a position which releases the igniter carrier, or by moving the actuator 9 to the right, in which case the igniter carrier pushes the finger 21 and causes the cover part 15 to close. The igniter carrier is thus moved below the finger 21 and the cover part 15 is secured in the closed position.
