21 Claims. (Cl. 219-32) The present invention relates to a cigar lighter and more particularly to a new and improved wireless type lighter which is energizable by normal household electricity.

The wireless type of cigar lighter has been and is generally utilized in motor vehicles and over a period of years there has been developed for such use an exceedingly satisfactory, economical and trouble-free electric lighter. As it became more apparent than an electric cigar lighter could be advantageously utilized in a household, mounted either in its own cabinet or in an appliance such as a stove, radio, etc., and energized by normal household electricity, it had been proposed to adopt the wireless type automotive lighter for such purposes. This had decided advantages in that such a lighter had the above mentioned desirable characteristics and also it obviates the redesigning of a new lighter and the tooling of manufacturing machines to produce a new type of lighter. There have heretofore been several factors which negatived the use of the wireless lighter in household applications, as for example the large differences in voltages, the possibility of short-circuiting of the lighter when using normal household voltage, the possibility of an electric shock to a user and other obvious deterrents. According to the present invention, however, these detrimental factors have been overcome to provide a wireless type lighter of substantially tandard automotive design which is utilizable in household applications.

It is an object of the present invention to provide a new and improved wireless type of cigar lighter which may be safely energized by normal household electricity.

Another object of the present invention is to provide in a cigar lighter of the above type for the utilization of components, which have been substantially standardized for automotive use in a household lighter.

A further object of the present invention is to provide a cigar lighter of the above type which is economical to manufacture, is easily and simply mounted in household appliances or in its own cabinet and which is substantially trouble-free in operation.

In attaining the above objects there is provided a substantially standard cigar lighter plug which carries at one end a heating coil which is brought to incandescence by energization from a 6 or 12 volt electrical source. The plug is normally stored and energized within a retainer well which is secured to a household appliance and the plug is removable therefrom for use. Also provided is a transformer for reducing the household voltage to a value which may be safely utilized by the heating element. In addition to the usual switch between the plug and the well, there is further provided in the primary circuit of the transformer a switch which is actuated by the plug after the previous switch is closed so that the latter switch absorbs the effects of the making and breaking of the circuit. This switch when actuated by the plug, exerts an eccentric force on the plug which tends to make the plug eccentric in the well but the present 'ice invention provides for preventing eccentricity and any malfunctioning which may be caused thereby.

In addition to a new and improved type of plug and switching means, the present invention employs economical parts which are easily and inexpensively assembled. These parts include a clamping shell for holding the switch in position on the well to be actuated by the plug and a mounting bracket for maintaining the lighter secured in an aperture in a household appliance.

Other features and advantages will hereinafter appear.

In the drawing:

Figure 1 is an elevation of the cigar lighter of the present invention with a portion of the appliance in which the lighter is mounted being shown.

Fig. 2 is a view taken on the line 2-2 of Fig. 1.

Fig. 3 is a view somewhat enlarged taken on the line 3-3 of Fig. 1.

Fig. 4 is a view partly in section of the well looking down thereinto.

Fig. 5 is an axial section of the well looking outward with a portion of the bimetallic arms being shown in dotted lines.

Fig. 6 is an end view of the clamping shell.

Fig. 7 is a side view of the clamping shell.

A cigar lighter of the instant invention has particular utility when it is mounted within an appliance such as a radio or stove or in its own cabinet and hence in Fig. 1, it is shown as it would be in a household appliance or its own cabinet 10 in which a side 11 of the appliance is provided with an opening 12 to provide access to the lighter. The appliance further has a base 13 on which is mounted a step-down transformer 14 for reducing the normal household voltage of -120 volts to either 6 or 12 volts, depending upon the resistance of the lighter. Screws 15 secure the transformer to the base 13 and a pair of leads 16 and 17 extend from the lighter to be connected to a source of normal household current. This may be accomplished within the appliance or else by having a separate plug on the end of the leads suitable for engagement within a household electric socket.

The transformer 14 is of the type which prevents, in case of malfunctioning, any short-circuiting between the primary and its secondary and hence prevents the secondary from having the household voltage impressed thereacross. In addition, since electric power is only intermittently transformed by the transformer, the transformer rating is less than would be required if power were being continuously transformed, and hence a more economical transformer may be safely employed.

As shown in Fig. 3, the lighter comprises a removable plug generally referred to by reference numeral 18 and a retainer well 19 into which the plug is positioned for storage and energization with the plug being removable therefrom for lighting tobacco. The plug has a spiral igniting coil 20 at its inner end contained within a cup 21. A circular ceramic plug 22 having an axial radial sectional shape as shown is mounted on the other side of the cup 21 and held in place by a rivet 23 which also connects one end 24 of a substantially cylindrical interconnecting member 25 to the cup 21.

It will be appreciated that one end of the spiral igniting coil 20 is connected to the rivet 23 while its other end is welded to the cup 21. A plastic plug 26 is connected to the other end of the interconnecting member 25 while a spiral spring 27 surrounds a substantial length of the interconnecting member and is held thereagainst by a spring retainer cup 28. Surrounding the exterior of the retainer cup is a cylindrical friction sleeve 29 having the shape shown. The sleeve 29 is adapted to move frictionally within limits on the retainer cup 28 while the interconnecting member 25 and the two

plugs

22 and 26 are capable of'moving inwardly with respect to the spring retainer cup 28 against the action of the spring 27. A knob 30 is threadedly secured to the plastic plug 26 to form a handle for the complete plug 18. The knob 30, interconnecting'rnember 25,

plugs

22 and 26 and cup 21 form an integral unit which is axially'movable as a unit with respect to the sleeve 29 and retainer cup 28.

The lower end of the retainer well 19 has mounted therein a ceramic plug 32 and secured thereto by an annular plug retainer 33. A rivet 34 extends axially of the plug 32 to fasten a pair of oppositely disposed bimetallic arms 35 thereto in addition to a safety stop element 36 which prevents contact between'the rivet 23 and the rivet 34. The other and of the rivet 34 is threaded as at 35 and a nut 38 secures 'th'eriyet onto the plug 32. The end 37 extends beyond the nut 38 and threaded thereon is a replaceable fuse 39 of the type which blows under an extended heavy load. A lead 40 connects to an input terminal 41 of the fuse.

In the operation of the lighter, inward axial force on the knob 30 causes the parts to assume the dotted line position shown in Fig. 3 in whichthe cup '21 engages and is clasped by the bimetallic arms 35. Upon passage of suficient current through the igniting coil, to cause the 'coil to reach incandescence, the arms 35 expand outwardly releasing the cup 21 and permitting the spring 27 to cause the plug 18 to protract out of the well 19 a short distance to the normal storage position shown in full lines. The plug is removable from the well when the coil is incandescent for use to ignite tobacco.

It will be appreciated that the relative dimensioning between the cup 21 and the bimetallic arms 35 is critical and must be maintained in order to assure thatthe plug will be released when it has reached the desired degree 'of incandescence without being underlieated or overheated. In order to prevent the making and breaking between these elements, there is provided a normally open switch 42 which is connected in the primary circuit of the transformer 14 and serves to make and break the electrical current to the lighter while the cup 21 is in engagement with the arms 35. The switch 42 also serves to prevent energization of the primary of the transformer except when the coil is being energized. To this end, the switch 42 contains a stationarycontact arm 43 and a flexible contact arm 44, both of which are formed from resilient material. A pivoted switch actuator 45, formed of insulating material such as ceramic, is utilized to force the arm 44 against the arm 43 to close the's'witch.

' The

arms

43 and 44 and actuator 45 are mounted on a U-shaped switch support member 46. To this end,

there is provided on the upper end of the member 46 a rivet 47 for connecting together the two arms and a flatspring 48 together with insulating segments 49 positioned therebetween. In addition, a pivot pin '50 on which the actuator 45 is pivoted extends between the legs of the member 4-6. The actuator 45 includes a cup engaging portion 51, a spring engaging portion 52 and a contact arm engaging portion 53. Thecup engaging portion extends through an aperture 54 in the well 19 which is substantially T-shaped and has ends 55 and 56 of the crossarm. The legs of the member 46 are outwardly curved as at 57 to conform to the exterior of the well about the aperture 54 and in addition have straight projecting lugs 58 and 59. These lugs are of unequal dimension as are the ends: 55 and 56 of the T aperture 54 and hence they serve to prevent placement of the switch support member 46 on the well at none but the correct position. In addition by maintaining substantially closed tolerances in the lugs 58 and 59 and the aperture 54, accurate positions of the cup engaging portion of the actuator 45 with respect to the bimetallic arms are simply and easily effectuated.

In the above structure, movement of the cup 21 toward the bimetallic arms 35 first causes contact with the arms, then additional movement of the cup causes it to engage and move the cup engaging portion 51 to counterclockwise pivot the actuator 45 to close the switch 42 and final movement of the cup causes latching by the arms 35. The pivoting of the actuator 45 causes the spring engaging portion 52 to engage the spring and also causes the contact engaging portion 53 to engage the movable contact 44 to close the circuit. The relative position of the parts when the switch is closed is shown in dotted lines in Pig. 3. Upon release of the cup 21 by the arms 35, the plug moves outwardly and prior to its disengagement between itself and the arms 35', it allows the actuator 45 to reversely pivot under the force of the spring 48 to permit opening of the contacts. The cup engaging portion 51 exerts an eccentric force on the cup 21 and to prevent the cup from being forced to one side, which would tend to cause malfunctioning between the cup and the bimetallic arms, the plug 18 of the present invention provides for maintaining the cup in axial alignment with the well. In accomplishing this, the friction sleeve 29 has an inner end portion '60 of reduced diameter which has a close sliding fit with the cylindrical surface portion 61 of the ceramic plug 22 having the largest diameter. In addition, the knob 30 has a shoulder 62 which has a close sliding fit with the inside surface of the spring retainer cup 28. As the cup 21, as part of the hereinbefore mentioned integral unit, moves inwardly the portion 61 of the plug 22 engages the portion 60 of the sleeve 29 to provide concentricity therebetween while the shoulder 62 of the knob engages the inside of the spring'retainer cup '23 to also provide for concentricity. The sleeve 29 has a close sliding fit with the well and is maintained thus by the well concentric therewith and it in turn maintains the spring retaining cup 23 concentric with the well. Accordingly, the cup 21 is maintained concentric with the well irrespective of the eccentric force of the actuator. As shown in Figs. 6 and 7 there is provided a clamping shell 63 for holding the switch 42 on the well 19. This shell is formed from sheet metal and has a longitudinal slot 64 with a rib 65 opposite thereto and a bent out terminal 66 formed by bending out a portion of the rib 65. The end corners of the slot are bent outwardly as at 67. There is additionally provided a pair of opposite ribs 68 for reasons which will be hereinafter apparent.

With the clamping shell mounted on the well, theterminal 66 is utilized as a connection in the secondary circuit. To provide energization of the coil 21, there is provided a wire 69 connected between one side of the secondary circuit of the transformer and the terminal 66, the other side being a wire 40 connecting to the terminal 41. The primary circuit of the transformer 14'has a wire 71 con nected to the lead 16 while the lead 17 connects to the stationary arm 43. A wire 72 connects the movable arm 44 to the other side of the primary. 'It will accordingly be appreciated that the switch 42 is in the primary while in the secondary there is provided in effect a switch be tween the cup 21 and bimetallic arms 35 and the fuse 39. The voltage in the primary circuit is insulated from the well or other user accessible portions of the lighter by the insulating segments 49 and by the actuator'45 bein formed of insulating material. Accordingly, the lighter of the present invention elfectively nullifies the possibility of electrical shocks occurring to a user by the voltage of the primary circuit.

The lighter of the present invention is mounted to have the knob 30 when in normal storage position to be flush with the outside of the appliance and yet be easily accessible and to this end there is provided a mounting cup 73, preferably decoratively plated, which has an upper outwardly directed flanged end portion 74 and a lower inwardly directed flanged end portion 75. The well 19 has its outer end portion 76'reversely bent for engagement with the lower flanged end 75with an insulating washer 77 preferably positioned therebetween. The outer flange 74 rests on the exterior of the appliance side 11 and in order to provide a clamping of the lighter to the side 11, a somewhat U-shaped mounting bracket 78 is provided. This bracket has an annular bight portion 79 and upstanding legs 80. The bracket is positioned with respect to the other elements with the lower end of the well 19 located within the bight portion 79 and the ends '81 of the legs positioned against the inner surface of the appliance side 11 adjacent the flanged edge 74 to clamp the edges of the appliance adjacent the opening therebetween. A nut 82 screwed onto the lower end of the well secures the parts in position and exerts the force to cause the clamping action. In addition the intermediate portions of legs 80 of the bracket 78 have inwardly bent flanges 83 which engage the ribs 68 of the shell 53 to prevent rotation therebetween while the slot 64 and switch 42 prevent rotation between the shell and well.

In assembling the lighter the cup 731 is first positioned in the aperture in the opening 12 of the appliance, the well 19 is inserted therein along with the Washer 77. The switch 42 is positioned on the well with the lugs 58 and 59 located in the ends 55 and 56 of the aperture 54. The clamping shell 63 is then positioned on the well by telescoping it on the well from the lower end thereof with the switch 42 positioned in the slot 64. The outwardly bent ends 67 of the slot serve to facilitate the initial locating of the switch in the slot. The annular bight portion 79 of the bracket 73 is then passed over the lower end of the well and the nut 82 screwed thereupon to cause the ends 81 of the bracket and the flange '74 to compress the edges of the opening 12 therebetween. In addition, the nut 82 serves to cause a clamping action on the lower flange 75 of the cup between the upper edge of the shell 6?: and the end portion 76 of the well. Thus only a single element clamps and maintains the parts together and to the appliance.

In some instances wherein the cup is normally secured to the appliance, either by molding a portion of the cup therein or by welding or other well known means, the mounting bracket 73 is not required. In this situation, merely screwing the nut 82 against the clamping shell 63 will serve to secure the lighter to the appliance. It will be appreciated that employment of the cup positions the plug, when in normal storage position, recessed below the face of the side 11 of the appliance. If desired, the cup may be completely eliminated and the lighter secured to the side of an aperture in the appliance merely by clamping the edge of the aperture between the clamping shell and the end portion 76.

It will thus be appreciated that there has been disclosed a new and improved wireless type of cigar lighter for use in home appliances and adapted to be energized by normal household electrical current. The lighter of the present invention utilizes parts which have become substantially standardized and known for their trouble-free performance and long life, in addition to being economical to manufacture. The parts of the lighter are simple and economical to fabricate and also they are capable of being easily and inexpensively assembled to produce a substantially trouble-free wireless type electric cigar lighter.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
