Application June 27, 1956, Serial No. 594,200

2 Claims. (Cl. 219-32) The present invention relates generally to improvements in electric lighters, and relates more particularly to improvements in the construction and operation of cigarette lighters or the like adapted especially for use in automobiles and similar vehicles.

A primary object of my invention is to provide an improved electrically operable lighter which is extremely simple and compact in construction and which is moreover highly etficient in lighting cigarettes, cigars or the like.

As shown and described in United States Patent No. 2,557,225 granted to me on June 19, 1951, it has heretofore been proposed to provide an electrically operable cigarette lighter adapted to receive a cigarette and having a fixed heating element for lighting the same as air is drawn through the heating element by means of the engine intake manifold. While lighters constructed in accordance with the disclosure of my prior patent have performed satisfactorily, the heating element thereof was fixedly mounted in the lighter assemblage and the entire lighter in fact formed a unitary assemblage which was adapted to be fixedly secured in some accessible location such as on the vehicle dashboard. As a result, the use of these previously proposed devices has been undesirably restricted since the heater portion of the lighter could not be removed at will for use in lighting cigars or pipes.

It is therefore a more specific object of this invention to provide an electric lighter which obviates all of the ob jections and disadvantages of prior devices intended for like purpose.

Another specific object of the present invention is to provide an improved electric lighter having a removable heating portion for lighting cigars or the like of non-uniform size and also being provided with a tubular opening accessible from the exterior and extending to the heating element for receiving and lighting cigarettes or the like of relatively uniform size.

Another specific object of my invention is to provide an improved lighter for use in automobiles or the like which embodies a receptacle adapted to be secured in fixed position on a desired portion of the vehicle dashboard or the like and connected by means of a passage with the intake manifold of the engine so as to provide breathing means and a removable lighter portion normally confined within the receptacle but readily removable therefrom and having a heating element adapted to be moved from an inactive position within the receptacle to a position wherein it is electrically energized and is located adjacent to the air passage to thereby effect lighting of a cigarette inserted withir. a tubular opening in the lighter.

- Another specific object of this invention is to provide an improved electric lighter for use in automobiles or the like which is extremely flexible in its adaptations and which is moreover exceptionally safe in operation and enables lighting of such articles as cigarettes by merely inserting 'the same within the lighter instead of necessitating removal of the heating element for lighting the cigarette when held in the mouth of the operator.

Still another specific object of the present invention is to provide an improved combination cigarette and cigar lighter which comprises relatively few parts, all of which are readily accessible for inspection and/or repair, and which moreover provides for the automatic lighting of cigarettes without necessitating removal of the heating element for elfecting such lighting and which also provides for the manual lighting of cigars in the usual manner.

An additional specific object of the present invention is to provide an improved two-piece lighter in which one part is affixed in the desired locality of a vehicle and contains an electrical connection normally de-energized and means for creating a suction while the other part is removably received by the first part and includes a heating element normally tie-energized but adapted to complete the electrical circuit for energization thereof when moved to a pre-determined position Within the first part and which furthermore includes means for receiving a cigarette to be lit by the heating element and an insulated gripping portion for manipulating the same.

These and other additional objects and advantages of the invention will become apparent from the following detailed description.

A clear conception of the several features constituting the present improvement and of the mode of constructing and of utilizing an electric lighter embodying the invention may be had by referring to the drawing accompanying and forming a part of the present specification wherein like reference characters designate the same or similar parts in the several views.

While the invention has been particularly shown and described as being especially applicable to electrically operable lighters for cigarettes and cigars adapted for attachment to the dashboards of automobiles or similar vehicles and with the air line extending to the intake manifold, it is not intended or desired to unnecessarily limit or restrict the invention by reason of such disclosure since the improved lighters could obviously be used for igniting other articles and may be located in any desired portion of the vehicle such as the back of the front seat with the air line being connected with any suitable source of suction such as the vehicle windshield wiper. It is also contemplated that certain descriptive terms used herein shall be given the broadest possible interpretation consistent with the disclosure.

Referring particularly to Figs. 1 to of the drawing, the improved electric lighter shown therein comprises, in general, a stationary receptacle or receiving member 15 having an outwardly open recess and being fixedly secured in any suitable manner to the dashboard 16 or the like of a vehicle; means such as a flexible conduit 17 forming a suction passage communicating with the recess of the receptacle 15, the flexible conduit 17 being preferably connected with the intake manifold of the engine, not shown, and leading centrally into the recess of the receptacle 15 near the bottom thereof; electric contact means in the form of a bimetallic member having spaced gripping and contact fingers 18 mounted within the recess of the receptacle 15 near the bottom of the recess about the suction inlet thereto, the contact fingers 18 being connected as by the wires 19 to a source of electrical energy which may conveniently be the electrical system of the engine in accordance with wellknown practice; a heating or igniting member 20 normally confined within the recess of the stationary receptacle 15 and having an insulated gripping portion or knob 21 projecting outwardly therefrom, the heating member 20 also having a heating element 22 at the in ner end thereof which is provided with an annular grooved contact portion 23 engageable by the contact fingers 18 of the stationary member 15 to energize the heating element when the heating member 20 is moved within the recess of the stationary member toward the bottom thereof whereupon the grooved contact portion 23 is gripped by the fingers 18 to complete the electrical circuit; means forming a constantly open generally tubular passage-way 24 extending axially through the heating member 21) outwardly from the heating element 22 for receiving a cigarette 25 or the like; means such as a compression spring 26 seated within the bottom of the recess and coacting with an annular seating element 27 having spaced ejector fingers 28 extending outwardly therefrom and engageable with an annular shoulder 29 on the heating member 20 for constantly resiliently urging the member 20 outwardly to the full line position in the drawing whereby the contact portion 23 of the heating element 22 is normally out of engagement with the stationary contact fingers 18.

The heating member 20 is normally retained in position within the recess of the receptacle 15 as by means of a suitable number of spring fingers 31 stamped from the inner wall 30 of the receptacle 15 and resiliently coacting with an annular shoulder 32 formed on the body of the member 20; and the spring pressed ejector fingers 28 which coact with the member 20 to urge the same outwardly may be suitably guided in their movement so as not to interfere with the fixed contacts 18. The member 20 may accordingly be used in automatically lightin articles such as cigarettes of substantially uniform diameter by merely inserting the cigarette 25 within the tubular passage-way 24 so that the inner end of the cigarette seats on or immed at y adjacent to U 6 heating element 22, and the member 20 need then only be pushed inwardly toward the bottom of the recess against the action of the spring 26 whereupon the bimetallic contact fingers 18 engage and grip the contact portion 23 of the heating element to complete the electrical circuit and energize the element 22. As the element 22 becomes energized, suction is drawn through the element 22 adjacent to the inner end of the cigarette to effectively light the same, and when the heat given off by the heating element reaches a predetermined degree, the bimetallic fingers 18 are caused to expand outwardly and release their grip upon the portion 23 whereupon the spring 26 and ejector arms 28 will return the member to its normal full line position and the lit cigarette may be removed by the operator. For lighting cigars or other articles which cannot be inserted within the tubular passageway 24, it is only necessary to push the member 20 inwardly as above described, and when the spring 26 returns the member 20 to normal position, it may be readily removed from the recess of the stationary member 15 by means of the insulated portion 21 so that the heating element 22 thereof may be used in a customary manner.

With more particular reference to Figs. 6 to 13, the somewhat modified lighter illustrated therein also comprises, in general, a receptacle or receiving member 45 having an outwardly open recess and adapted to be fixedly secured to an accessible part of a vehicle; flexible conduit means 47 forming a suction passage establishing communicationwith the engine intake manifold or the windshield wiper mechanism and a central portion of the recess near the bottom thereof; fixed electric contact means having an annular series of spaced bimetallic gripping and contact fingers 48 projecting outwardly from the bottom portion of the recess about the suction inlet, the contact means being connected by electric wires 49 to a source of electrical energy; a heating or igniting member 50 normally confined within the recess of the receptacle 45 and having an insulated gripping portion 51 projecting therefrom, the member 50 also having a spirally wound heating element 52 carried at the inner end thereof and which is provided with an annular grooved contact portion 53 engageable by the spaced contact fingers 48 of the stationary member 45 to energize the heating element 52 when the member 50 is moved toward the bottom of the recess of the member 45 to a position wherein the grooved contact portion 53 is gripped by the bimetallic switch fingers 48; means forming a constantly open passage-way 54 extending axially through the heating member 50 outwardly from the heating element 52 for receiving a cigarette 55 or the like; means in the form of a compression spring 56 seated within the bottom portion of the recess of the stationary member 45 and coacting with an annular seating member 57 having an annular series of spaced ejector fingers 58 extending toward the open end of the recess and en'gageable with an annular shoulder 59 formed on the heating member 50 for constantly resiliently urging the member 50 outwardly toward the position shown in Fig. 6 whereby the electrical circuitis open with the contact portion 53 of the heating element out of engagement with the stationary contact fingers 48.

In this modified form of lighter, the heating member 50 is alsonorrnally retained in position within the recess of the receptacle 45 as by means of an annular series of spring fingers 61 which may conveniently be stamped from the wall of the stationary member 45 and which resiliently'coact with-an annular shoulder 62 formed on the member 50 to prevent displacement thereof. Likewise, the spring pressed ejector fingers 58 which coact with the shoulder 59 of the member 50 to constantly resiliently urge the same outwardly may be suitably guided in their reciprocable movement as by means of guide lugs 60 which may also be conveniently stamped from the wall of the member 45 to thereby prevent displacement of the ejector fingers. As in the case of the lighter shown in Figs. 1 to 5, the member 50 may be used for automatically lighting cigarettes by inserting the cigarette 55 within the passage-way 54 until the inner end of the cigarette rests near the heating element 52, whereupon the member 50 is positioned inwardly toward the bottom of the recess of the member 45 against the action of the spring 56 until the bimetallic spring contact fingers 48 engage and grip the contact portion 53 of the heating element 52 to thereby complete the electrical circuit and energize the heating element. During energization of the element 52, suction is constantly drawn through the line 47 to thereby cooperate with the heating element to light the cigarette; and when the heating element has heated to a pre-determined extent, the bimetallic fingers 48 automatically separate and release the grip upon the portion 53 to permit the spring 56 and ejector fingers or arms 58 to automatically return the member 50 to the position shown in Fig. 6, whence the lit cigarette 55 may be removed from the tubular passage-way 54 by the smoker. Also as in the case of the lighter previously described, the member 50 may be used for lighting cigars and other articles not receivable within the tubular portion 54 by merely first pushing the member 50 inwardly so as to energize and heat the heating element 52 and by removing the member 50 entirely from the recess of the stationary member 45 after the lighter has been automatically returned to normal position by the spring 56 and ejector arms 58.

From the foregoing detailed description, it is believed apparent that the present invention contemplates the provision of an improved electric lighter which is extremely simple and compact in construction and which is moreover highly flexible in its adaptations. The improved lighter assemblages may be readily installed, and by incorporating the heating element 22, 52 directly in the removable portion 20, 50, cigarettes may be either lit automatically without need for removing the portion 20, 50 or cigars and cigarettes or the like may be manually ignited by complete removal of the member 50 with the aid of the insulated knob portion thereof. The improved devices may be readily fabricated with the various parts being formed of sheet metal and/or plastic with suitable insulation being provided as shown. While two embodiments of the invention have been shown and de scribed, it is believed obvious that the primary difference between the lighter shown in Figs. 1 to 5 and the modification shown in Figs. 6 to 13 resides in the provision of a greater or lesser number of spaced fixed contact fingers 18, 48, a greater or lesser number of spaced ejector fingers or arms 28, 58 and a greater or lesser number of spaced spring retaining fingers 31, 61. Essentially the lighters described are the same in both construction and operation, and in each case, the heating element is an integral part of the removable heating or igniting member. With particular reference to Fig. 13, it will be noted that the inner portion of the generally tubular passage-way 54 in the modified lighter is shown as being hexangular in shape and it is preferable to form the inner portion only of such shape so as to more readily accommodate cigarettes of slightly varying diameters.

It should be understood that it is not desired or intended to limit this invention to the exact details of construction herein shown and described, since various modification within the scope of the appended claims may occur to persons skilled in the art to which this invention pertains.
