8 Claims.

The present invention relates to lighters for the ignition of fuel in lighting devices which employ the combustion of a fuel-air mixture at a mantle surface as a source of light, and, more particularly, to lighters for the initial ignition of liquid gasoline at the mantle surface of gasoline lanterns, the lighters being provided with clamping means for attachment to frame members of lanterns of conventional design for positioning the lighter in operable relation with the lantern without any modification of the lantern structure. A

Gasoline lanterns provide light by the combustion of a gasoline vapor-air mixture at a mantle surface. Liquid gasoline, stored in a reservoir in the lantern base, is forced under air pressure from the reservoir through a heated generator in which the liquid fuel is vaporized into a mixing chamber, where it is mixed with air to form a combustible fuel-air .mixture which is burned at a mantle surface, the mantle being surrounded by a glass lantern globe.

Prior to ignition of the lantern, liquid gasoline passing through the generator is not vaporized and is injected into the mantle as a liquid. To light the lantern, the lantern globe is raised and a lighted match or other flame propagating means is held near the mantle to light the liquid contained therein. Alternatively, the gasoline may be ignited by allowing gasoline vapors to collect within the lantern globe and by inserting a match into the globe through one ofseveral holes in the lantern frame beneath the globe. The lighting of the lantern by either of these two methods exposes the user to the possibility of an explosion caused by the ignition of the vapors which may collect within the lantern globe. Also, these methods are inconvenient for the user, since a match must be available if the lantern is to be used and since the match must actually be lighted and inserted into the lantern into a position adjacent the mantle surface. These methods of lighting the lantern have also proved unsuitable for use when it is necessary to light the lantern under adverse weather con ditions. In the case of wet weather, any available matches may ,be unsuitable for use and. under conditions of extreme cold, the manual dexterity ofthe user desiring to light the lantern may be so impaired that it would be impossible for him to strike a match.

The present invention provides a lantern lighter assembly by means of which a lantern may be lit without the use of a separate flame propagating means and without the necessity of raising the lantern globe or exposing the user to any danger of explosion of the fuel vapors. The lighter assembly of the present invention consists of a lighter which utilizes the spark produced by friction between a pyrophoric material such as flint and steel to ignite the lantern fuel and clamping means by which the lighter may be removably attached to the lantern frame. The lighter base carries the clamping means and the spark generating elements of the lighter assembly and serves to form the component parts of the assembly into an integrated structure. The entire assembly is so constructed that it may be attached to the frame of a conventional gasoline lantern as a single unit and retained in position during actual operation of the. lantern without any modification of the lantern structure. The lighter assembly is so positioned on the lantern frame that it lies beneath the mantle so as to lgnite the liquid gasoline or gasoline vapors issuing therefrom. The lighters of the present invention are extremely simple in operation and may be employed without the use of" that degree of manual dexterity necessary for the lighting of a match and consequently may be used under extreme weather conditions.

Three embodiments of the lighter of the present invention are illustrated in the accompanying drawings. One form of the lighter comprises a lighter base clamped to the lantern frame within the area defined by the lantern globe, the light base carrying a pair of supports between which a serrated steel wheel is suspended. A flint or other pyrophoric material is resiliently supported in close frictional contact with the wheel by means attached to the base. The wheel may be moved against the surface of the flint by means of a handle which extends beyond the lantern frame. The gasoline contained in the mantle may be lighted by vertical movement of the handle from a position outside the lantern to move the steel wheel across the flint, the friction between the flint and the steel wheel producing a spark which will ignite gasoline vapors issuing from the mantle. This form of the lighter of the present invention may be used with conventional lantern structure with only slight modifications of the lantern construction.

The second embodiment of the light assembly of the present invention comprises clamping means removably attached to the frame of the lantern and a lighter base secured to the clamp ing means and carrying a drip pan which is positioned directly beneath the mantle. Gasoline dripping from the mantle is caught by the pan and is conducted to a catch basin located in the lower portion of the lighter. A serrated steel wheel and a pyrophoric material such as a flint in close frictional contact therewith are attached to the lighter base. In conventional gasoline lanterns, the frame member supporting the glass globe is apertured to provide for the entry of air necessary to support combustion at the mantle surface. The steel wheel may be rotated by means of a handle attached thereto and which extends beyond the frame of the lantern through an air passage in the lantern frame. The friction generated between the wheel and the flint upon rotation of the wheel produces a spark which is deflected downwardly to light the liquid gasoline contained in the catch basin. A flame from the ignited gasoline at the lantern base passes to the drip pan and thence to the mantle, igniting the gasoline contained therein. The novel construction of the clamping means and the provision of the handle extending through the apertures present in conventional lanterns makes possible the use of this embodiment of the lighter assembly of the present invention with such conventional lanterns without any alteration .or modification of the lantern construction.

The third form of the lighter assembly of the present'invention comprises clamping means removably secured to the frame of the lantern and a lighter base attached to the clamping means carrying an apertured drip pan positioned directly beneath the mantle. If desired, a wick of asbestos or other suitable absorbent non-inflammable material may be inserted in the aper-' tures-of the drip pan. A serrated steel wheel is carried by an axle rotatably supported byjthe lighter base, the wheel being in close frictional contact with a flint or other pyrophoric material also carried by the lighter base. The wheel axle may be rotated by a rack and pinion gear arrangement, the pinion being secured to the axle and therack being carried by a housing attached to the lighter frame. A red, formed as an extension of the rack and projecting outside the area defined by the lantern globe through an aperture such as that above described, provides a convenient method of moving the rack within its housing to cause a, corresponding rotation of the pinion, the axle and the steel wheel. Friction generated by the rotation of the wheel against the flint causes a spark to be projected from the surface of contact between the wheel and the flint into the liquid gasoline contained in the drip pan or the gasoline absorbed by the wick. The flame produced in the drip pan serves' to ignite the liquid asoline contained in the mantle thus completing the ignition of the lantern. This embodiment of the lighter assembly may also be employed with gasoline lanterns of conventional construction without changing the design of-the lantern.

It is, therefore, an important object of the present invention to provide a lighting device for the ignition of liquid fuel at a mantle surface, which device eliminates the need of a separate flame propagating means and which may be employed under adverse weather conditions.

It is another important object of the present invention to provide a lighter assembly comprising clamping means for attachment to the frame of a gasoline lantern and a spark-generating lighter secured by said clamping means in close proximity to the lantern mantle to insure the safe and convenient lighting of the lantern by rotating the wheel, the friction developed upon.

rotation of the wheel in contact with the pyrophoric member being sufficient to produce a spark for ignition of the fuel contained within the mantle.

It is a still further important object of the present invention to provide a lantern and lighter assembly comprising a lantern utilizing the combustion of a fuel-air mixture at a mantle surface as the source of light and a lighter mounted on said lantern adjacent the mantle surface and operable to ignite liquid fuel passing through the mantle during the initial lighting of the lantern.

Other and further important objects of this invention will beapparent from the disclosures in the specification and the accompanying drawmgs.

As shown on the drawings.

In Figure 1, reference numeral III refers generally to a gasoline lantern comprising a fount II, a collar portion I2 mounted on the fount II, a lantern frame I3 secured to collar I2, and a ventilator assembly I4 removably mounted on the frame I3. The lantern frame I3 is apertured as at I3a for a purpose to be hereinafter described.

The fount I I defines a reservoir chamber I5 for elevational view of the the storage of gasoline and has an aperture I:

and a bushing I! by means of which the reservoir may be filled with gasoline. A plug I 8 carried by bushing II closes the aperture I6. The fount I I also carries a plunger pump assembly I9 which.

of the reservoir. Gasoline may flow out of the reservoir I5 through fuel line 2I, which extends from the lower portion of the reservoir upwardly through an aperture Ila in the upper wall of fount II. The flow of gasoline through line 2| is controlled by a needle valve 22. An adaptor nipple 23 is threaded at one end to the outlet side of valve 22 and is supported on frame member 24 by a lock nut 25. The other side of nipple 23 is attached to a generator 26 by a lock nut 21. The generator tube 26 extends upwardly from adaptor nipple 23 to the upper portion of the lantern within the confines of ventilator assembly l4.

'Air tubes 28 are supported by frame members 29 and extend upwardly into the ventilator M. The air tubes 28 are bent inwardly toward each other at their upper extremities and yoke block 36 and yoke 3| are supported by the air tubes. A bolt 3| a secured to the upper portion of yoke 3| passes through anaperture 32 in ventilator assembly l4, the assembly l4 being secured to bolt 3|a by lock nut 33. Yoke block 30 has a hollow central chamber not shown) in communication with the atmosphere through air tubes 29 and apertures |3a in frame member I3. The generator tube 26 is bent downwardly as at 2611 and passes through the upper wall of yoke block 36 to communicate with the central chamber formed therein.

An injector 34 is carried by yoke block 36 to receive a commingled stream of fuel vapor and air formed in the hollow central chamber of yoke block 30, as will be explained later. The outer periphery of the injector 34 is grooved as at 35 adjacent its mouth 36 to receive a draw string 31 which supports a mantle 38. A cylindrical glass globe 39, supported by frame I3, is provided to surround the illuminating elements of the lantern.

In the initial lighting of the gasoline lantern, as hereinbefore described, the reservoir l5 may be filled with gasoline through bushing H. The pressure in the reservoir I5 is increased by pumping air into the reservoir by means of pump l9. Increased pressure in the reservoir l5 forces liquid gasoline through the fuel line 2| and, by operating needle valve 22, fuel is passed through the adaptor nipple 23 into the generator tube 26. The liquid fuel is passed through the generator 26 through the yoke block 30. Yoke block 30 is provided with an orifice (not shown) from which the gasoline passes through the injector 34 into the mantle 38. The liquid gasoline thus introduced into the mantle 39 will pass through the mantle, due to its porous construction, and will drip from the mantle to the lower parts of the lantern which lie beneath the mantle.

, Prior to the present invention, in order to light the lantern In it has been necessary, for instance, to'raise the glass globe 39 and inserta lighted match into the interior of the globe to a position adjacent the mantle 38. The flame from the match served to ignite the gaseous fumes confined within the glass globe. This procedure is not only dangerous, due to the possibility of an explosion, but also inconvenient, since the globe may only be raised until it contacts the under surface of the ventilator assembly |4, thus providing a restricted area through which the match may be inserted into the globe.

The lighter of the present invention is indicated by reference numeral 49 of Figure 1. As seen in Figures 2 and 3, the lighter base 4| is attached to frame member 24 by means of screws 42 and carries a pair of generally triangular supporting members 43. A serrated steel wheel 44 is rotatably supported by shaft 45 between supports 43. As illustrated in Figure 3, a handle 46. formed from a single sheet of metal and having flanges 46a depending from a central web member 46b, is

6 attached at one end to wheel 44, the other end of the handle 46 projecting beyond the frame member l3. The web 46b is cut away at the point of attachment between the handle 46 and the wheel 44, the wheel being secured to the flanges 46a, which extend on either side thereof. The lighter base 4| supports a depending cylindrical member 49, one end of which is closed by a set screw 50 and from the other end of which a flint 5| projects. Flint 5| is held in frictional contact with wheel 44 by a spring 52 compressed in member 49 between set screw 50 and flint 5|. The contact between flint 5| and wheel 44 is main- ,tained by the setting of screw 50 within member 49. A spring 53, secured at one end to the base 4| and at its other end to the underside of web 46b, resiliently supports the handle 46 in a horizontal position.

A portion |3a of frame member I3 is cut away to allow vertical movement of the handle 46, and a portion |2a of the lantern collar portion I2 is cut away to allow access to the cylindrical member 49, set screw 50 and flint 5|.

In the operation of the lighter 40, liquid gasoline admitted into the mantle 38 through the injector 34 by opening valve 22, vaporizes within the area defined by the globe 39. By moving the handle 46 downwardly against the action of spring 53, the serrated wheel 44 is moved across the surface of the flint 5|, thus generating a spark. This spark ignites the gasoline vapor within the globe 39 which in turn ignite the gasoline contained in the mantle 38. Thus, the lighting of the gasoline in the mantle 38 may be easily and safely accomplished, without the necessity of lifting or otherwise moving the glass globe 39, by merely depressing the handle 46 of the lighter 40.

The means for securing the lighter to the lantern frame and the spark generating means are each carried by the lighter base 4|. The base 4| thus serves to form the complete lighter assembly into an integrated device which functions as a unit to accomplish the initial lighting of the lantern.

A second form of the lighter assembly of the present invention is illustrated in Figures 4 and 5 of the accompanying drawings. As shown in Figure 4, the reference character 54 refers generally to a second form of the lighter of the present invention. The lighter 54 comprises an upstanding lighter base 55 formed with flanges 56 and 51 which extend laterally in opposite directions. Flange 56 is attached to clamping means 59 by set screws 58. The clamp 59 is clamped to frame member 29 by a set screw 59a. The lighter assembly is secured to the frame member 29 between the adapter nipple 23 and air tube 28 as shown in Figure 5. The second lateral flange 51 has an upturned lip portion 6|) to form a catch basin 64 for a purpose to be hereinafter described.

The support member 55 is formed with an integral deflected portion 6| which is stamped or otherwise formed to provide a convex dish-like drip pan portion 62. The lighter 54 is attached to the frame member 29 in such amannerthat dished portion 62 lies directly beneath the mantle 38, as illustrated in Figure 5. The gasoline passing through the apertured mantle 38 will be collected in dished out portion 62 of projection 6|, the gasoline flowing from portion 62 into channel 63 which is formed integrally with the lighter frame member 55 and which connects dished portion 62 and catch basin 64. The gasoline dripping from mantle 88 is thus conducted to the catch basin 84.

A flint and steel type spark generator, indicated generally at 85, is employed to ignite the gasoline in catch basin 84. A hollow cylindrical member 86 is attached to frame 55 in a position overlying the catch basin 84 by means of metal strap 61 and screw 68. One end of member 66 is closed by a set screw 69 for a purpose to be hereinafter explained. The other end of member 86 is cut away to provide two arms 18 which rotatably support a shaft 14 therebetween. A serrated steel wheel 1| is secured to shaft 14 and is rotatable therewith between arms 18. Wheel 1| and shaft 14 may be rotated by means of an extension of shaft 14 which extends beyond the confines of frame I3 and globe 39 through apertures I30. in frame member I3, as shown in Figures 4 and 5. Extension 15 is provided with a knurled knob 16 to facilitate rotation of the shaft "by the user.

A flint 12 is resiliently supported in frictional contact with wheel 1| by spring 13 confined within member 86 between flint 12 and set screw 69. The tension on spring 13 and the pressure transmitted to flint 12 to hold the flint in contact with the wheel may be varied by adjustment of set screw 89. The lighter base 55 carries the complete clamping means, the spark generating means and the drip pan and serves to form the lighter assembly into a unitary structural unit.

The operation of the igniter 54 is as follows: The spark generated by rotation of steel wheel 1| in contact with flint 12 is deflected downwardly to ignite the liquid gasoline contained in catch basin 84. The flame thus produced in catch basin 64 will serve to ignite the gasoline in the dished out portion 62 and subsequently the gasoline in mantle 38, completing the lighting operation.

The lighter assembly 54 is of such size and design as to fit on frame member 29 in a position adjacent the adapter nipple with the dished out portion lying directly beneath the mantle 38. The lighter may be mounted upon any lantern of conventional construction such as that illustrated in Figure 1 due to the provision of the novel clamping means 59 and the presence of apertures I3a through which the handle 15 may extend.

In Figure 6 reference character 88 refers generally to a third form of the lighter assembly of the present invention. As illustrated in Figure 7, the lighter assembly comprises a lighter frame 8|, the lower portion of which is bent to form a laterally extending flange 82 which is secured to clamping means 83 by means of screws 84. Clamp 83, which is similar in construction to clamp 59 of Figure 4, is removably secured to frame member 29 of lantern I8 by set screw 85. The flange 82 of frame member 8I- is removably secured to clamping means 83 by set screws 84. The side portions of frame member 8| are bent laterally to form parallel flanges 88 and I88 which extend in a direction opposite to that of flange 82. A drip pan 81. having a central dished out portion 88, underlying the mantle 98, as shown in Fig. 'I, s attached to the support member 8| by a flange 89 formed integrally with drip pan 81 riveted to member 8| as at 98. The drip pan 81 is apertured as at 9| for a purpose to be hereinafter described.

A generally rectangular housing 92, having an integrally formed flange 92a, is secured to flange 88 of support member 8| by screws 92b passing through

flanges

86 and 92a. Housing 92 encases a rack gear 98 which is movable therein. Rack 98 is retained in housing 92 by flange 94 formed integrally with housing 92 and separate flange which is secured to housing 92. Flange 95 is apertured as at 95a to receive a rod 96 formed as an extension of rack 93. As may be seen in Figures 6 and '7, rod 96 extends through an aperture I3a formed in lantern frame I3 as hereinbefore described and is provided with an end button 98 to facilitate movement of the rod by the user. A spring 99 is confined between the inner surface of the button 98 and the outer side of flange 95. The spring 99 holds the lower end 93a of rack 93 in abutment with the inner side of the flange 95.

A shaft IN is rotatably carried by flanges 88 and I88 of support member 8|. Shaft I8I may be rotated by pinion gear I88 secured thereto at a position adjacent one end thereof and in mesh with the rack 93. A serrated steel wheel I82 is secured to the other end of axle IM and is rotatable therewith. A housing I84 of rectangular cross-section is secured to flange I88 by means of screws I85. A set screw I86 is threaded into one end of housing I84 to compress spring I81 confined within the housing. A flint I88 is resiliently supported in frictional contact with wheel I82 by the spring I81 in the housing I84.

If desired. an asbestos wick I89 may be provided for insertion into the apertures of drip pan 81, as illustrated in Figure 6. The wick I89 will absorb the gasoline which may drip into the drip pan 81 from mantle 38. The lighter frame or support member 8| carries the clamping means for attaching the lighter to the lantern, the spark generating elements and the means for moving these elements as well as the drip pan and serves to form an integrated structural unit of the entire lighting apparatus 88.

In the operation of the lighter, as illustrated in Figures Band 7, the rack 93 may be moved within the housing 92 by a pressure applied to the button 98 against the action of spring 99. The movement of the rack will cause a corresponding movement in the pinion gear I88, the axle IM and the steel wheel I82. A sudden release of the pressure exerted on the button 98 will release the pressure holding the spring under tension and the spring will force the rack rapidly downward within the housing 92. This rapid movement of the rack'93 will cause a corresponding movement of the pinion I88, the axle MI, and the wheel I82. The friction generated by the movement of the steel wheel I82 against flint I88 will generate a spark which will be deflected directly into the drip pan 81, igniting the liquid gasoline contained therein, or, if wicks I89 are employed, igniting the gasoline absorbed by the wicks. The burning of the gasoline under drip pan 81 will ignite the gasoline contained in the mantle 38 thus lighting the lamp.

This embodiment of the lighter assembly may also be employed with lanterns of conventional design without any change or modification in the lantern construction.

Thus it may be seen that we have provided a lighter assembly for use in the lighting of gasoline lanterns by means of which the lantern may be safely and easily lighted without danger or inconvenience to the user. The novel clamping means provided for the lighter makes possible the use of the lighter with lanterns of conventional design.

It will, of course, be understood that various details of construction may be varied through a wide range without departing from the principles of this invention and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
