LIGHTER Irving Flor-man, New York, N. Y. Application March 31, 1942, Serial No. 437,061

6 Claims.

This invention relates to lighters and especially to table lighters of the pyrophoric type. It presents an improvement on the lighter described in my prior application S. N. 431,572, filed February 19, 1942. The primary object of the invention is to provide a lighter of this type which is convenient and easy to operate and which is fully efiective.

In the past, most types of table lighters, that is lighters formed in two parts consisting of a base and a torch member removably mounted in the base, have operated through some cooperation between the base and the torch. In other words, either the lighter was operated during removal of the torch, which required a heavy base, or the holding of the base with one hand; or the lighter after removal from the base has required some sort of contact with a cooperating part on the base to cause it to ignite. The primary object of the present invention is to provide a base type lighter in which the torch member is operative when removed from the base without any cooperation with the base, and entirely independently thereof; although the torch may be extinguished by returning it to its position in the base.

A further object of the invention is to provide a torch type of mechanism in which the lighter body is held between the second and third fingers and the lighting is caused by pressure of the thumb. More particularly, the invention contemplates a lighter construction having an elongated body adapted to be engaged between the second and third fingers and provided with a flange forming an abutment for engagement by these fingers, with a button on the opposite side of the flange engageable by the thumb and connected to the lighting mechanism so as to operate the lighter when depressed.

Still another object of the invention is to provide in a lighter of this kind a simple mechanism controlled by the thumb button which creates a strong spark capable of igniting the wick. More especially, the invention contemplates a pawl connection between a bar connected to the button and the sparking wheel, with a special construction for maintaining the bar in proper position after each operation.

Further objects and advantages of the invention will appear more full from the following description, particularly when taken in conjunction with the accompanying drawings which form a part thereof.

In the drawings:

Fig. 1 shows in side elevation, with parts broken away, a lighter embodying my invention.

Fig. 2 shows in side elevation the torch member in operated position.

Fig. 3 is a top plan view of the lighting mechanism of the torch member.

Fig. 4 is a cross-section on the line l4 of Fig. 3; and

Fig. 5 is a bottom plan View of the torch with the bottom removed.

The. base of the lighter may be any suitable size and shape, and it is shown in the drawings as an ornamental glass bottle 2. This cap is provided with a central opening forming an entrance to a metal tube 6 which extends inwardly into the base 2. It should be understood however that any type of base having an opening into a chamber or Well therein would come within the contemplation of the invention.

The torch member has a body composed of a tube 8 closed by a wall In at one end. The other end is provided with an external thread l2. In the neighborhood of but spaced from I; this second end is a transverse plate member I4.

This plate member however does not entirely close the casing, but provides an abutment for retaining the cotton wadding l6 for holding fuel. Fuel may be supplied to the wadding by pouring it into the end of the casing 8 past the Wall I4;

Mounted on the closed end In of the casing are upstanding cars 29. Extending through the top Wall I l) is a wick tube 22 in which is mounted a suitable wick 24 which extends downwardly into the cotton Hi to receive fuel therefrom. Likewise extending through wall Ill, and at its other end through wall I4, is a flint tube 26 closed at its inner end by a threaded plug 28 (I and containing a coil spring 30 pressing outwardly a flint 32. Flint 32 engages the surface of a flint wheel 34 rotatably mounted on a shaft 36 in the ears 2!]. Arranged beside and rigid with the flint wheel 34 is a ratchet wheel 38.

Slidably mounted in a tube or bore 54 and passing through the top wall it and also the wall !4, is a bar or rod 55 of somewhat smaller size than the tube I. At the end opposite the lighting mechanism this rod carries a transversely extending arm 58 provided with a centering pin fill. A coil spring 62 engaged between arm 58 and plate I4 urges rod 56 away from the lighting mechanism (downwardly in Fig. 3). Centering pin 60 engages in a conical base portion 64 of a pin or button 66 slidable in a closure 68 which is threaded on the thread [2 and thus closes the body 8. At its upper end in Fig. 3, rod 56 has a series of pawl teeth which engage the teeth of ratchet wheel 38.

Bar 56 is provided in its rear face, opposite the teeth ID, with a notch 72. A bowed leaf spring 14 has its ends within this notch and its center portion resting against the back of bore 54.

The mechanism thus described operates as follows:

When the torch is within the base in the position shown in Fig. 1, it is removed by sliding the first and second fingers beneath the flange 69 of body 68. It is then turned over to the position shown in Fig, 2, with the thumb engaging and pushing upwardly on button 66. This pushes upwardly on rod 56. Pawl bar 56 engages ratchet wheel 38, and as the button 66 is advanced the flint wheel 34 is turned clockwise in Fig. 3 and throws a spark from the flint onto the wick, thus igniting the wick.

When the pressure of the thrunb is released, spring 62 pushes the bar 58 downward. In this movement, the teeth 18 slip over the teeth of ratchet wheel 33, this being permitted by the play of the rod in the bore, against the action of spring 14. When the rod is again moved upward, the same operation will of course be repeated.

To extinguish the torch, it is only necessary to restore it to the base 2, from which it can readily be removed for a further operation.

While I have described herein some embodiments of my invention, I wish it to be understood that I do not intend to limit myself thereby, except within the scope of the appended claims.
