A. E. IRELAND CIGARETTE LIGHTER Filed Aug. 18, 1958 ALFRED E. IRELAND l f A 1/ April 19, 1960 United States l Patent CIGARETTE LIGHTER Alfred E. Ireland, Oaklyn, NJ. Application August 18, 1958, Serial No. 755,758 Claims. (Cl. 677.1)

The present invention relates to a cigarette lighter, and more particularly to a cigarette lighter having a llint supply of great capacity.

A wide variety of cigarette lighters have been proposed having a ilint capacity suiiicient for a plurality of flints. However, in the main, these prior lighter constructions have not proved to be satisfactory for at least one of several reasons.

Thus, in most prior constructions, the flints are springurged upwardly by spring means in which the spring tension exerted by the spring varies as the supply of lints becomes exhausted. Generally, in prior constructions, the spring tension exerted by the spring means on the flints decreases as the supply of ints becomes exhausted.

In other constructions, the loading of the reservoir or container for the lints is diiiicult. Still other disadvantages include the possibility of loss of fluid through the f iint reservoir, complex construction of the llint reservou', etc.

This invention has` as an object the provision of a novel cigarette lighter.

This invention has as another object the provision of a cigarette lighter having a large int capacity.

This invention has as a still further object the provision of a cigarette lighter of foolproof construction in which positive feeding of the iiints is achieved.

Other objects will appear hereinafter.

For the purpose of illustrating the invention there is shown in the drawingsa form which is presently pre-V ferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumen' talities shown.

Referring to the drawings wherein like reference characters refer to like parts:

Figure 1 is a vertical sectional view through the cigarette lighter of the present invention. A

Figure 2 is a sectional view taken on line v2-2 of Figure 1.

Figure 3 is a sectional view Figure 1.

Figure 4 is a sectional view taken on line 4-4 of Figure l.

Referring to the drawings, the cigarette lighter of the present invention is designated generally as 10. Such cigarette lighter comprises the casing or housing 12, of any desired shape or contour. The casing 12 comprises the base 14 and the top 16; A cover 18 for the cigarette lighter 10 is hinged by means of hinge 20 in operative juxtaposition to the top 16.

taken on line 3-3 of The casing 12 includes a wick compartment 22 and a flint compartment 24.

The wick compartment 22 comprises the wick 26 which is surrounded with the usual fluid retaining filter 28, which may comprise cotton batting or similar means, in which the fluid fuel, such as a low boiling petroleum distillate is carred. The wick 26 projects through the wick bushing 30 which is carried on the top 16 of casce i 2 ing 12. A refueling plug 32 is provided on the base '14,

of casing 12, such refueling plug 32 being threaded into the base 14 and being in liquid-tight communication with the wick compartment 22 when received within the. base 14. The liquid-tight seal between the refueling plug 32 and the base 14 is maintained by the O-ring 34 which is provided intermediate the refueling plug 32 and an O-ring receiving recess in the base 14.

The construction of the cigarette lighter 10 set forth above is generally of conventional construction to the extent which the same has been given so far, and it is to be understood that any one of the wide. variety of modifications to such construction which are known tov the art may be made.

The iiint compartment 24 is disposed within the wick compartment 22 and comprises an imperforate outer tube 25 for retaining the interior of the int compartment 24 out of communication with the wick compartmentV 22. Elongated tube 36, which extends from the base 14 to the top 16, is concentrically disposed within outer tube 25.

The uppermost portion 38 of tube 36 is tapered outwardly from the top towards the bottom. Preferably,

the uppermost portion 38 of tube 36 is imetallurgicallyV joined as by brazing to the top 16 of casing 12. The lips 40 of tube 36 serve as a guide for the uppermost flint 42 carried within the liint compartment 24. Within the tube 36 is disposed the flint holder 44. The ilint holder 44 is a hollow threaded bolt, which is threaded along substantially its entire length and is provided with a bore of suliicient diameter to nestingly receive a plurality of

iiints

42, 42a, 42b, et seq., eight ilints 42 being shown received within the int holder 44 in the illustrated embodiment. of llint holder 44 is not threaded, but is matingly tapered with the uppermost portion 38 of tube 36, such upperl most end portion 46 of tlint holder 44 being received against the uppermost portion 38 of tube 36.

The tube 36 is provided with a vertical ,slot 48 which extends for substantially the entire height of the tube 36, A nut 58 is threadably secured to the threads on the flint holder 44. Nut 5i) is provided with an ear 52 which is received Within the slot 48. By virtue o'f the recep-` tion of the ear 52 in the slotV 48, rotation of the flint holder 44 will cause the nut 50 to ascend or descend on the flint holder 44. The flint lholder 44 is providedV with a pair of

opposed slots

54 and 54 which extend vertically for a major portion of the height of llint holder 44. A coil spring 56 is carried on the nut 50 and has its uppermost free end 58 disposed within the bore 60 in flint holder 44. The free end 58 of coil spring 56 extends through both of the slots 54 with the tip of free end 58 being supported on the coil spring 56,.as shown in Figure 2. The coil spring 56 serves as a follower, its free end 58 engaging the bottomrnost face of the bottommost flint 42g and spring-urging the ints 42 42g upwardly. The coil spring 56 embraces the int holder 44 which serves to guide it.

The flint holder 44 is supported at its bottommost por-" tion vby the basal cap 62 which is threadably received within the base 14. The end face 63 is juxtaposed to the end of tube 36, as seen in Figure 1. The basal cap 62 comprises a bored screw having a concave face having a slot 64 for receiving the end of a screw driver, and threads 66 on its stem, which threads 66 mate with mating threads in the base 14.

The flint holder 44 comprises a solid rod. end projection 68 which extends through the basal cap 62. The projection 68 is notched at 70 to permit the iiint holder 44 to be rotated.

The projection 68 is provided at a spaced distance Patented` Apr..

The uppermost end portion 46` above notch 70 with a circular notch 76 within which the keyset screw' 72 projects. The set screw 72 serves to guide the rotation of the projection 68.

A spark wheel 74 is rotatably mounted a spaced distance above the lips of the' tube 36 for engagement with the flint 42.

The' basal cap 62 may be` provided with' an O-ring receiving recess within which an O-ring 75 may be' received intermediate the shoulder of int holder 44 which is juxtaposed to the basal cap 62 and the end face of the basal cap 62. An -ring receiving recess may be prow vided in the base 14 below the threads 66 to receive an` O-ring 78.

The center portion of the concave face of basal cap- 62 is' counterbored at 80 to facilitate insertion of a tool into the notchY 70.

The operation ofA the cigarette lighter 10 of' the present invention is as follows:

The ints 42 42g are loaded intothe flint holder 44r byunscrewing the basal cap 62 from the base 14 and removing the flint holder 44 and basal cap 62 from the cigarette lighter 10, and' loadingthe llints into the mouth ofthe hint holder 44. During the loading of the iiint holder 44, the nut Si) should be positioned near the bottom of the slot 48.

When the iiint or tlints are loaded into the nt holder 44,` the flint holder 44 and the basal cap 62 are inserted into the cigarette lighter and the basal cap 62 is threadably secured: into theV base 14. The requisite degree of'tension can be exerted on the flint or lints within the ilint holder 44by rotation of the iiint holder 44 through inserting the head of a small tool, the edge of. a coin, or a fingernail into the notch 70 of projection 68 of iiint holder 44 and rotating the int holder 44 in that fashion.

As the flint supply within the hint holder 44 becomes expended due to usage by engagement with the spark Wheel 74, the iiint holder 44 may be rotated as aboveindicated to spring urge the portion of the int or the topmost flint against the spark wheel 74. Since the nut 50 may follow the int or flints up the flint holder 44, a constant degree of spring pressure may be exerted on theiiint or hints in this fashion. The alignment of the tiint or flints with the sparkV wheel 74 is insured by the alignment of the mating tapers of the uppermost end portion 46 of int lholder 44 and uppermost portion 38 of tube 36.

The present invention may be embodied in other speciiic forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be be made to the appended claims, rather than to the oregoing spe'cication as indicating theV scope of the invention. Y
