10 Claims.

This invention relates to pyrophoric lighters and more particularly to lighters of this type embodying torch means mounted on a rod or the like adapted to be deposited, for example, in a fuel receptacle, the torch being caused to ignite upon withdrawal of the supporting rod from the receptacle.

The objects of the invention include the provision of an unusually simple, inexpensive, and highly dependable lighter of the above indicated type, and a lighter which may be used for relatively long periods of time without refilling with fuel and without renewal of the pyrophoric material.

According to preferred embodiments of the invention, either the fuel receptacle or the torch supporting rod may be provided with pyrophoric material, adapted to be engaged by abradant means so arranged that during the initial part of the movement of withdrawing the rod and attached torch from the receptacle, the abradant means will not immediately scratch over the pyrophoric means, but after the withdrawal movement has become accelerated, then the abradant means is vigorously and very rapidly scratched along the pyrophoric material, with the result that ignition of the torch is assured upon its leaving the receptacle.

Various further and more specific objects, features and advantages will clearly appear from the detailed description given below, taken in connection with the accompanying drawing which forms a part of this specification and illustrates merely by way of example, certain preferred forms of the invention. The invention consists in such novel features, arrangements and combinations of parts as may be shown and described in connection with the devices herein disclosed.

In. the drawing, Fig. l is a perspective view of a lighter embodying the invention;

Fig. 2 is a central vertical sectional view of a lighter embodying the invention in one of its forms;

Fig. 3 is a view similar to Fig. 2, but showing the torch member of the lighter partially removed and illustrating a somewhat different embodiment of the invention;

Fig. 4 is a horizontal sectional view taken substantially along the line 4-4 of Fig. 2;

Fig. 5 is an enlarged perspective view of the abradant means of the type 'used in the device of Fig. 2; and

Fig. 6- is an enlarged detailed view partly in section and partly broken away, showing the inflammable torch element which may be-used with the invention, and the adjacent portions of a rod for supporting the torch.

Referring to the drawing in further detail, the lighter there shown may comprise a relatively large receptacle III for containing a mass of absorbent material such as cotton II, which may be saturated with inflammable liquid introduced, for example, through a filling opening as at I2. The filling opening as shown is located in the top wall of the receptacle, although it may be located in any other wall of the receptacle at a point where it will not interfere with any decorative features thereon. The filling opening may be normally kept closed as by a screw plug l3. The screw plug may have an enlarged head adapted to be received in an enlarged upper portion 12a of the filling opening. When the screw plug is out, the enlarged portion [2a of the opening may serve in effect as a small funnel to aid in introducing the fuel.

The receptacle It may be provided with a cover L or top wall It permanently sealed on to the casing and a bottom wall l5, also permanently sealed in respect to the casing walls. The bottom wall "5 may be flanged downwardly and then outwardly, for example, as indicated at It, to provide an enlarged supporting base area for the device. The base or flanged edges thereof also if desired may be attached to a relatively heavy weight or ring as at l1, formed for example of lead. Thus a weighted base of large area is provided insuring stability of the device during its operation as it rests on a table or other support.

Within the receptacle ll, preferably at or adjacent its central portion, a tube l8 may be mounted and sealed through the top and bottom walls of the receptacle. This tube provides a cavity for slidably receiving a torch member l9 carried by a longitudinally movable rod 20. The upper end of the rod 20 may be provided with a handle 2| threaded as at 22 or otherwise substantially permanently secured to the rod.

As shown in Fig. 6, the torch member l9 may comprise a short length of hollow braided wick material or the like as at 23, surrounding a screw member 24, threaded into the lower end of the rod 20; The lower end of the rod 20 may be suitably concaved as at 25 to receive the upper ends of the wick piece 23 and thereby preventing fraying of the edges of the wick. The lower edges of the wick piece 23 may be suitably secured in respect-to the screw member 24 as by an encircling wire or the like 26.

As the torch member normally rests within the lighter receptacle, it may be received within a hollow cylinder or cylinders as at 21, formed of absorbent felt or the like and having internal diameters such as to closely embrace the wick piece 23. The felt cylinder pieces 2! may be mounted within a cylinder of sheet metal as at 28 closely fitting the interior of the lower end of the tube l8. The upper edges of the metal cylinder 28 may he turned over as at 29 to secure the felt against upward displacement. The side walls of the cylinder 28 may be perforated at one or more areas as at 30 and the adjacent portions of the walls of the tube 18 may be similarly perforated as at 3| whereby fuel from the absorbent cotton ll may be gradually transferred to the felt cylinder members 2'! and thence to the wick piece 23 on the torch I 9, so that the supply of fuel on the torch is replenished while the torch rests within the receptacle.

The lower end of the cylinder 28 may be provided with a threaded engagement as at 32 with the lower end of the tube l8 and the lower end of the cylinder 28 may be provided with a bottom wall flanged and knurled at its periphery as at 33 to enable the user to screw out the cylinder 28 and the enclosed felt for inspection, cleaning or replacement of the felt from time to time. With the cylinder 28 removed from the lighter receptacle, the felt cylinders maybe readily removed through the upper end of the cylinder 28 by flexing same past the retaining flange 29.

Within the central portion of the tube ill, a'

restricted cylindrical guiding sleeve or cylinder may be fixed as indicated at 34. It will be noted that the cylinder 34 has a central aperture just large enough to permit the torch to readily pass therethrough. This aperture is in alignment with the central apertures in the felt members 21, so that the torch member is guided into the latter and the upper ends of the felt members are protected against wear or dislocation by the insertion of the torch. At the same time, the insertion of the torch when lighted, into the guide member 34, serves to extinguish the flame before it can be brought adjacent the felt cylinder members which are saturated with the fuel. The upper end of the opening in the member 34 may be suitably flared as at 35 to permit the torch to be more readily inserted.

A plurality of vertically extending strips of pyrophoric material as at 36 may be mounted around the interior walls within the upper end of tube l8. Or in some cases it may be possible to provide a mass of pyrophoric material in the form of a hollow cylinder closely fitting within the upper end of the tube Hi. In either event the pyrophoric material preferably comprises substantially a complete ring encircling or extending around the opening within the upper end of tube l8. This substantially complete ring of pyrophorlc material insures that as the abradant means carried by the rod 20, as hereinafter described, is removed, the abradant means will scratch over the surface of at least one or more sectors or segments of the pyrophoric material regardless of how the abradant means happens to be turned about the rod 20, when the latter is resting in the lighter receptacle ready for operation. The provision of the pyrophoric means in the form of a cylinder or ring also enables a relatively large amount of this material to be positioned in a small space so that there will be ample pyrophoric material available for using the lighter over a period many times longer than possible with the usual lighter, without replacing the pyrophoric element. The strips of pyrophoric material if desired may be carried as a unit within a thin sheet metal cylinder 31 suitably flanged at its upper and lower ends as shown and adapted to be quickly inserted or removed from the upper end of the tube IS. The pyrophoric strips may be secured to the interior of the cylinder 31 either by adhesive or by reason of the flanged construction of the cylinder 37 and associated parts acting in cooperation with the sector shaped strips.

The upper end of the tube It may be formed for threaded engagement with a removable ierrule 38, knurled at its upper outer edge and adapted to be removed to permit inspection, repair or replacement of the pyrophoric members or other parts within the tube I8. The ferrule 33 may have its central opening somewhat flared as at 39 to receive a correspondingly tapered lower end portion of the handle 2| for thus effectively sealing the upper end of the tube l8 against the escape of evaporated fuel. The flared opening 39 also permits the torch member to be more readily inserted.

The form of abradant means carried by the rod 20 as illustrated in Fig. 2, is shown in further detail by the perspective view of Fig. 5. This form may comprise a metal cylinder 40 drilled at its upper end at 4| to closely but slidably receive the rod 20. The lower end of the member 40 may be hollow as indicated at 42. The abradant means per se may comprise one or more relatively sharp steel scraping members as at 43 and 44, preferably integrally formed with spring steel supports as at 45, which supports in turn may be fixed at their upper ends to the member 40 as by screws 46. As shown in Fig. 5, each of the abradant members as at 43 and its integral yieldable supporting arm may be received within a slot as at 41 extending longitudinally of the member 40. Upon the withdrawal of the member 40 from its normal position within the ring of pyrophoric material, the members 43 and 44 scrape along the surfaces of the pyrophoric material under yielding pressure, with the consequence that glowing particles of the pyrophoric material fly off in directions generally radially inwardly of the member 40, so that the torch when within or adjacent the member 40, will become ignited. In order to give the sparks thus produced, more ready access to the torch when within the cavity 42, the side walls of member 40 adjacent the members 43 and 44 may be cut away as at 48 and if desired, apertures as at 49 may be cut through the spring supports 45.

With the embodiment of the invention shown in Fig. 2, a coil spring 50 may be mounted on the rod 20 between the torch and the member 40 for a purpose hereinafter explained in connection with the description of the operation of the device. This spring will serve to yieldably limit longitudinal movement of the abradant means along the rod 40 in a direction toward the torch. Longitudinal movement of the abradant means in a direction toward the handle 2| may be limited by the handle itself or by a. resilient washer formed of fiber or rubber and secured within the base of the handle around the rod 20. This resilient washer 5| will serve to prevent any noise from occurring due to striking of the member 40 against the lower end of the handle 2|.

As shown in Fig. 6, the enlarged lower end of the rod 20 may be provided with an upwardly extending flange as at 52 if desired, for surrounding the lower end of the coiled spring 50 and 7 avatar.

therebyv protecting the spring against the flame rodlfl and the attached torch freely upwardly untllfthefupper end of the" spring5ii extends'into and engages" the member All. Thereup'on further upward movement of the handle 21 will serve to substantially compress spring 50, since the memi-j ber 40 will tend-to remain in its initial position because oftheengag'emerit of the sharp abradant members and M with the pyrophoric material. However; after the springbecomes sufliciently compressed to overcome this engagement, the member 40 will quickly spring upwardly under the influence of' the spring 50, with the result that the scraping 'acti'on of the abradantmembers 43 and against the pyrophoric members will be initiated with a'snap actionand carried throughwith a motionmore r'apid than the motion of the hand of the userin liftingthe torch. This will insure that a shower of sparks will be created within the, cavity of the member 40 at substantially the same moment that the wick piece 23 of the torch arrivesjat or adjacentthis cavity. Consequently as the'torch'is removed from the, upper end of the tube l8, it will be ignited. The lighter torch will then provide a convenient meansior'lighting cigars, cigarettes or pipes. The wick piece 23 is of sufficient size to carry a limited amount of fuel sufficient so that the torch with each operation, may be used to more effectively carry out all of the usual purposes of a lighted match, yet they flame is kept away from the fingers of the user and'at an'exposed point for convenient application to thematerial to be lighted. After the torch has been used,'it may be extinguished by simply thrusting it back into normal position in the lighter receptacle as shown inFignZ.

' In the embodiment of the invention illustrated in Fig. 3, all of the parts except for the abradant means and its associated parts, may be" similar to those of Fig. 2. "The abradant means may com prise a collar freely slidable on the rod 20. A pair of abradant elements as at iii and 62 may be mounted upon spring supports as at 63 attached as by screws to'collar 60. The rod 20 at a point adjacent its lower end near the torch, may have a collar fidfixed thereto for operating the abradant means when the torch is removed from the lighter; When the parts of Fig. 3 are in normal position, ready 'for' operation,'the handle 2!, rod 20 and the torch will be in positions corresponding to those shown in Fig.2; At the same time the collar 60 and the attached abradant or scraping members willbe down within the ring of pyrophoric material. In operating the device of Fig. 3, the user grasps the handle 2| as with the device of Fig. 2. Thereupon the torch rod 20 may be pulled upwardly freely with increasing acceleration. When the users hand and the torch have thus acquired considerable momentum, the collar 64 will engage between the spring supports 63 tending to spread them apart, causing the scraping members 6! and 62 to more firmly engage the pyrophoric material and thereafter almost immediately causing the scrapers and collar 60 to be quickly drawn up out of the ring of pyrophoric material. Thus the 'abradant elements are firmly held against the pyrophoric material as they are quickly scraped thereover with the momentum of the users hand and the torch, and hence as the torch leaves the top of the tube 18, its ignition will be assured. After the ie h h n. ,u sldt ma b re nsert a w th the de 'b f wh r ii ii eifwmk ce 23 w l ese a'i e riib' n em nt: w h the el cylinder members 21 torenew the supply of fuel on 'ih nd the abradant niihbers will againrestwithin the pyrophoric ring ready for. the next operation.

Q It will be understood that with both examples oi the invention shown in'iEigsl 2 "an d3,' as the de-' vice is used from time to time, the abradan't inem fber'sfwill' be reinserted invarious angular l po sitions with respect to the ring of py ophoric ma f terial' so that the wearing of thepyrophoric mael terial will be distributed among the various sec tors or segments thereof and. consequently the as; vice may be used for very ,longperiods of time without renewin the pyrophoric elements. How-I ever, whenlit becomes necessaryi'or" desirable 'to renew these elements, this frnay be quickly and. conveniently done ,upon' screwing oil the ferrule. 38. The life of the pyrophoric meansmayube even further extended if desired (by ,bmitting one of each pair. of the scraping or abradant.

members. Also if the, wick plece '23 "ofthe torchv member should become deteriorated or worn, it

may be quickly replaced upon removal. of the screw member 24. 1iurthermore,-the feltcylinder members 2] -for contacting with the wick may also be quickly replacedor cleaned ,when necessary after long periods of use, upon screwing out the member 33. Since all of the partswhichmay become worn or deterioratedafter long ,use'may be thus readily cleaned orreplaced, and since the device embodies no rotatable bearings" orother parts subject to any material wear. it will be ap-. parent that the device will be suitable. for use for manyyears.
