Sept. 1, 1959 R. G. ELLIOTT SAFETY LIGHTER Filed July 20, 1956 IN V EN TOR.

G. ELLIOTT RAYMOND United States Patent SAFETY LIGHTER Raymond G. Elliott, Pomona, Califi, assignor of onetenth to Gadget-Of-The-Month Club, Inc., Los Angeles, Calif., a corporation of California Application July 20, 1956, Serial No. 599,102 6 Claims. or. 44-35 This invention relates to devices for lighting domestic furnaces and industrial burners of all kinds and, more particularly, to a simple device having a wick therein which may be entered unlighted into a normally inaccessible combustion chamber. When the wick is positioned adjacent the burners, a match disposed in a sliding carrier is ignited by mechanical means adjacent the wick thereby lighting the wick which in turn may be used to light one or a plurality of burnersinteriorly of the combustion chamber.

Statistics concerning fires and accidents occurring during the process of lighting burners, heaters, floor furnaces and similar equipment, indicate that most of the injury and damage is caused by igniting fuel or fuel fumes which have escaped exteriorly of the enclosed and properly vented combustion chamber.

Typical is the case of a person lighting a furnace through a typical inspection door. As the lighted match is advanced toward the open door, previously liberated combustible gas which accumulates around andwithin the combustion chamber when no draft exists to carry it outwardly through the flue, is ignited before the match is entered through the door, thus drawing additional gas outwardly through the door and creating a sudden flash of flame around the person holding the match.

In the past there have been a number of lighting devices of the torch or flame applicator type which provided more or less satisfactory means for applying flame to remote places, and there have been a few lighters in which the flame was generated after the operative end of the devices were placed adjacent the burners, but those of the latter category were intended mainly for industrial purposes and were dependent upon batteries and spark coils for the generation of a pilot flame and hence were quite impractical both in size and operative requirements for use in domestic applications.

My invention hasbeen made with the-foregoing considerations in mind and can be said to have a plurality of important objectives.

One important object of my invention is the provision of a safety lighter device which may be introduced unlighted into the enclosed fire box or combustion chamber of a furnace and lighted when its operative end is adjacent the burner or other source of the fuel supply.

Another important object of my invention is the provision of a device of the character described which is minimal in size and entirely mechanical in operation, and requires no accessory equipment other than common materials present and available in the average household.

A further important object of my invention is the provision of a device of the character described which is adapted to provide a flame of brief duration or, when desired, a continuing flame for multiple lighting at various points.

; An additional important object of my invention is the provision of a device of the character described having means for extinguishing the pilot flame when no longer 7 Patented Sept. 1, 1959 required without removing the device from the combustion chamber.

In brief, the safety lighter device of my invention includes a longitudinally extended tubular main body having an axially aligned slot therein, and a handle member at one end and a paraflin impregnated wick disposed in the longitudinal bore of the tubular body and extending outwardly from the end thereof spaced from the handle, there being push-pull lever means positioned outwardly of the slot for extending the wick.

A cylindrical weighted match carrying member is slidably disposed upon the tubular body between the handle and the end spaced therefrom by means of a longitudinal non-axial bore therethrough adapted to slidably receive the tubular body.

A second longitudinal bore, dimensioned to receive the stick end of a conventional stove match therein, is disposed inwardly from one circular end of the carrier member, and is diametrically spaced from the through bore therein. A striker ring is affixed to the end of the tubular body adjacent the section of wick extending outwardly thereof, and is provided with a sharp inwardly disposed circumferential edge spaced outwardly from the tube so as to engage the head of a match sliding down the tube in the match carrier.

As previously indicated, the tube receiving bore through the cylindrical match carrier is off center, and the match receiving bore is disposed in the area of greatest radius relative to the through bore. This area is preponderant in weight and rotates downwardly under the tube as the carrier slides downwardly thereon so that when it reaches the end of the tube the lighted match is automatically positioned so that the flames arising therefrom immediately surround the wick.

Certain variations of' the embodiment described herein and further important objects of the present invention will become apparent in the following detailed description of one preferred form thereof when examined together with the references to the drawings, in which:

I Figure 1 is a diagrammatic view in perspective showing a safety: lighter constructed according to the principles of the invention;

Figure 2 is a similar perspective view, considerably enlarged, and with a central portion broken away to show details of the interior construction;

Figure 3 is a diagrammatic perspective view of the match carrying member of the assembly;

Figure 4 is a schematic .view similar to that of Figure 3 showing the method by which the match ignites the wick;

Figure 5 is a side elevational view of the wick adjustment means;

Figure 6 is an end elevational view of the wick adjustment member seen in Figure 5, and

Figure 7 is a diagrammatic view showing certain portions of the assembly in longitudinal section and portions of the wick and match in side elevation.

Reference is again made to Figure 1 showing a safety lighter device constructed according to my invention which is seen to include a handle portion 10 having a ring bail 11 extended therefrom, a tubular longitudinally extended main body portion 12 having a slot 13 disposed therein from adjacent the handle 10 to a point adjacent the end 14 spaced from the handle, and a wick member 16, a portion of which is outwardly extended through the aperture 15 of the tube 12.

A match carrying member 17 of generally cylindrical conformation and having a match 18 positioned therein is also shown in this figure to be slidably mounted on the tubular body 12 so that when the carrier 17 slides to the end 14 of the tube 12 the head of the match 18 comes into contact with the sharp rim of the striking ring 19 which is fixedly attached to the tube 12 adjacent the end 14 thereof. The mechanical means for striking the match are clearly indicated in the enlarged diagram of Figure 7 which shows the tube 12, the striking ring 19 and the match carrier 17 and part of the match stick 18in longitudinal section, and the wick member 16 and the match head and shoulder 18 in side elevation. It Will also be observed in Figure 7 that the striking ring 19 is provided with a plurality of circular grooves of progressively increased diameter on its inwardly disposed surface 20 so that the outer groove is terminated at the circumferent al edge 21, thereby presenting a sharp outer circumferential rim as seen at 22.

As can be seen in Figure 3 the match carrying member 17 is of generally cylindrical conformation and is pro: vided with a through bore 23, adapted to receive the tube member 12 slidably therethrough. It will further be noticed that the bore 23, although parallelling the longitudinal axis of the cylinder 17, is disposed substantially off center, and a match receiving bore 24 is entered parallel to the bore 23 in the cylinder area of greatest radius relative to the bore 23. A finger notch 25 is provided in the match carrying member 17 to facilitate entering the match within the bore 24 and the subsequent removal of the burned stick therefrom.

Because of the greater weight in the area of the cylinder 17 in the section thereofbeing of greatest radius relative to the bore 23, when the device is held in the diagonally downward position indicated in the. Figures 1-4, the match carrying cylinder 17 will rotate downwardly relative to the tube as it slides lineally thereon so that its heavier area will be under the tube upon arrival at the end 14 thereof, and the match 18 being ignited by forceful contact with the rim 22 of the striking 19 will be beneath the wick 16 and flame upwardly thereabout as shown in Figure 4.

As indicated in Figure. 1 and more clearly shown in Figure 2 a longitudinally extended wick member 16 is disposed interiorly of the axial opening 15 of the tube 12 and is removably attached to a push-pull, manually operated positioning member 26 which is disposed through the slot 13 and is: slidable lineally within the tube 12.

Details of the conformation of the positioning member 26 are shown in the side elevational view thereof in Figure to include a longitudinal section defining a thin band of strap material having holes 27 and 28 therethrough adjacent its end 29 which is normally disposed toward the end 14 of the tube 12. An upward extension of the. strap 26 adjacent its end 30 spaced from the holes 27 and 28, is bent laterally to provide a convolute arcuatedouble fold best seen in the end view thereof shown in Figure 6, and its upwardly disposed surface 31 which is positioned outwardly of the longitudinal slot 13. is roughly finished, as by knurling, to facilitate movement of the part with a thumb or finger-tip. The band 26 is dimensioned so that it may he slipped inwardly of the slot 13 in the tube 12 and is dimensioned in length so that. when moved downwardly in the slot 13 to the end 14, the end 29 together with the holes 27 and 28 therein will extend outwardly of the aperture 15 at the end 14 of the tube permitting the wick 16 to be entered through the holes 27. and 28. in the manner indicatedat 32; in- Figure 2.

The wick member 16 which is shown extended from the end aperture 15 of the device in Figures 1, 2 and 4, and shown in greater detail in Figures 2 and 7, is composed of paraffin impregnated fibre having substantially the, same longitudinal rigidity as stiff twine so that it is easily enterable through the holes 27 and- 28 yethas sulficient rigidity so that it'may be moved inwardly and outwardly of the aperture 15 of the tube 12 in response to corresponding movements of the positioning slide 26.

During: experimental and actual use tests, the safety lighter. device, as described hereinbefore was found to be adaptable to various applications. In cases where only one burner was to be lighted, the wick was retracted interiorly of the tube and only a match was used. In other instances wherein it was necessary to wait for fuel to accumulate or for combustible gas to form, the wick was moved outwardly of the tube and ignited before the flame of the match died out, and for other purposes, such as lighting church candles, in which neither the danger of explosions nor the problems of inaccessibility were involved, the wick was lighted directly by the match without placing the match in the match carrier for automatic striking and positioning as previously described.

Numerous modifications and variations of the present invention will occur to those skilled in the art after a careful study hereof. All such, properly within the basic spirit and scope of the present invention are intended to be included and comprehended herein as fully as if specifically described, illustrated and claimed herein.

The exact compositions, configurations, constructions, relative positionings, and cooperative relationships of the various component'parts of the present invention are not critical, and can be modified substantially within the spirit of the present invention.

The embodiments of the present invention specifically described and illustrated herein are exemplary only, and are not intended to limit the scope of the present invention, which is to. be interpreted in the light of the prior art and the appended claims only, with due consideration for the doctrine of equivalents.
