4 Claims.

This invention relates to a cigar lighter in which a spark is produced by a int rubbed by a hard member for igniting a burner.

Devices of this kind are in common use, and are made compact so that they may be carried in the pocket. It is one of the objects of this invention to improve, in general, devices of this character.

It is another object of this invention to `provide a device of this general character that automatically removes a snufer from the burner, and that causes ignition by a simple motion of translation. f

It is still another object of this invention to provide a lighter entirely housed inl a casing that can assume simple, smooth lines, and which has telescoping parts, so arranged that a telescoping movement causes a, lid to open and the burner to light.v In this way, the device can readily be held in the palm of the hand and operated by a grasping movement.

It is still another object of this invention to make it possible to obtain a very rapid angular motion of the knurled steel wheel that operates on the int, so as to facilitate generation of a spark. This is accomplished by rst storing energy, as in a spring, and then suddenly releasing it; and all this occurs as a result of a continuous telescoping movement of the two-part casing.

This invention possesses many other advantages, and has other objects which may be made more easily apparent from a consideration of one embodiment of the invention. For this purpose there is shown a form in the drawings ac companying and forming part of the present specification. This form will now be described in detail, illustrating the general principles of the invention; but it is to be understood that this detailed description is not to be taken in a limiting sense, since the scope of this invention is best defined by the appended claims.

Referring to the drawings:

Fig. 1 is a longitudinal sectional View on an enlarged scale, of a cigar lighter incorporating the invention, the cigar lighter being in inactive position;

Fig. 2 is a view, partly in section, of the cigar lighter after the ame has been ignited and ready for use;

Figs. 3, 4, and 5 are sectional views, taken respectively along planes 3 3, `4--4, and 5- of Fig. 1;

Fig. 6 is a view similar to Fig. 2, illustrating the position of the parts when the igniter is about to be operated;

is made of thin metal to form a generally hollow body. The left-hand end of the body is formed by a supplemental member 2, which is permanently attached to the casing body l as by the aid of a band 3.

A wall 4 is securely attached to the inside oi the casing to denne a fuel chamber 5 of relatively large capacity. This fuel chamber may be filled with some absorbent material, such as cotton wadding E (Fig. 1). This wadding has been indicated only in the left-hand portion of the chamber 5, but it is understood that it is intended to fill the entire chamber.

The Wall i has a horizontal portion which serves to support a burner body l (Figs. l, 2, and 5). Through this burner body 1 extends a wick 8. Flame 9 (Fig. 2) can burn when a spark is supplied to a region neighboring the wick. This wick is shown in Fig. 1 as being of considerable length and extending toward the right, underneath another horizontal portion 9 of the wall 4.

The filling of the chamber 5 with appropriate volatile liquid fuel is effected through an opening in the bottom of the casing, and which is provided by the inwardly directed integral sleeve I0 (Fig. l). This sleeve may be threaded -to accommodate a closer plug` il having a ilat slotted head l2.

For igniting the burner formed bythe wick 8 and the body l, sparks are generated between a flint member i3 and a knurled wheel I4 (Figs. 1, 2, 3, and 5). The flint i3 is guided by an upwardly sloping tube l5 which passes kthrough an opening in the sloping portion i6 of wall' t and immediately adjacent the wick 3. Flint i3 is urged into contact with the wheel' M, as by the aid of a compression spring il housed in the tube I5. The tube l5 extends downwardly into an opening formed in the depressed portions i8 of the member 2; and it may be threaded to accommodate the ilat head. closure screw ifi. This screw i9 has a spring guide and retainer extension 2ilaround which the lower end of the spring il is accommodated.

The casing member I has a tubular extension 2| over which telescopes a tubular cap 22. l This cap 22 completes the enclosure for the lighter. Apertures 54 in the sides of part I serve to supply air to the base of burner 1.

In order to ignite the burner, the wheel I4 is given a limited, violent rotation to strike sparks from flint I3. This is accomplished in a manner now to be described.

The wheel I4 is mounted for free rotation on a stationary hollow pin 23 (Figs. 1 and 3). This pin extends transversely through the casing part I, and is provided with a slotted head 24 at one end. At its other end it is threaded to accommodate a fastening screw 25. For mounting the Wheel I4 on the pin 23, there is provided a hanged sleeve 26 to which wheel I4 is firmly attached. Flange forms a ratchet wheel (Figs. 1, 2, and 5). This ratchet wheel is engaged 4by a pawl 21 (Figs. 1 and 2).

Pawl 21 is pivoted on a pin 26 that is carried by a cover member 29. A spring 30 urges the paWl 21 into engagement with the ratchet wheel 26.

The cover member 29 is formed with an upper smooth surface, as shown most clearly in Fig. 3, to close an opening formed in the upper wall of casing part I. It has depending spaced flanges 3l which are spaced so that they can enter between the sides of casing I. The cover is mounted for pivotal movement about the pin 23. For this purpose, the anges 3I are apertured for the reception of the hubs of a pair of pinions 32. These pinions 32 are securely attached to the flanges 3l, and are accommodated in the space formed between these flanges and the sides of casing part I.

In operating the lighter, the cover 29 is rotated in a clockwise direction from the position of Fig. 1 to the position of Fig. 2.

This movement of the cover rotate the wheel I4 by the aid of the pawl 21. Conveniently, the cover 29 may carry a snuffer 33 that depends downwardly from the cover, and that engages the sloping shoulder 34 on the burner body 1.

After the lighter has been put into use, the cover member 29 may be rotated in a counterclockwise direction from the position of Fig. 2 to the position of Fig. 1, thus extinguishing the iiame 9. This closing movement causes the pawl 21 to ride over a tooth of ratchet wheel 26 and into engagement with a succeeding tooth. In this way, the knurled Wheel I4 is not rotated during this closing operation.

The angular, clockwise movement of cover 29 is caused to take place at a very rapid rate, as by storing energy in a spring and then releasing the energy. This is accomplished by squeezing the two parts I and 22 of the casing together, as in the palm of the hand.

To accomplish this result, the pinions 32 are engaged by the racks 34 that are formed on opposite sides of a linearly movable support 35 that has an arcuate configuration to conform to a tubular slide 38. Support 35 is fastened to this slide; and, for this purpose, a pair of bosses 39 extend below the support 35and are attached to the slide 38. This slide 38 is guided for axial movement in the stationary arcuate guide 40, attached, as by welding or soldering, to the upper surface of horizontal wall 9 (Fig. 3), as well as to the end wall 43 of the housing (Fig. 1). This guide is slotted near its inner end (Fig. 1) to permit the support 35 to be fastened to the top of slide 38.

Telescoping movement of the part 22 over the 29 serves to (lll l'ne'.

portion 2l is used to store energy in a hairpin spring 44 that serves, when it is released, to give a quick motion to the support 35 and racks 34. One end of the hairpin spring is anchored at 45 in the flange 46 of a boss 4I attached to the inner surface of casing half 22. Its other end is anchored to a latch member 41 that is pivotally mounted about the support 35, as by the aid of the pivot pin 48. l

This latch member, as shown most clearly in Figs. 5, 7, 8, and 9, has a hook portion 49 which engages the inner edge 5I] of a slot 6I in the casing extension 2l.

Accordingly, as the part 22 is moved along the member 2l, the hairpin spring 4I is wound up, the racks 34 being restrained by engagement of the latch hook 49 with the edge 50.

Upon suiiicient inward movement of the casing half 22, the latch member 41 is rotated in a counter-clockwise direction to release the restraint against movement of the support 35. This is accomplished by the aid of a releasing or unlatching member 5I formed integrally with the flange 46.A It has a sloping surface adapted to contact a curved surface of the latch 41. In the position of Figs. 6, 7, and 9, this releasing member 5I has just reached the latch 41. A slight further movement will release the latch and cause the racks to move violently toward the left, and to the position shown in Fig. 2. This operates the wheel I4 and opens the cover 29. Rotation of this cover is stopped at the upper surface 5G of slide 35.

The ratchet wheel 26 has teeth spaced angularly less than the angular movement of cover 3l; for example, there being six teeth, the angular Spacing is sixity degrees; Whereas cover 3l moves through an angle of ninety degrees. Thus, when closing the cover 3l from the open position of Fig. 2, the pawl 21 will fall between a pair of teeth. Accordingly, when the cover is next opened, it will have acquired considerable speed before the pawl engages, and its kinetic energy is then useful to impart a rapid rotation to the wheel 26, the drag of flint I3 on wheel I4 being thus readily overcome even with a relatively light spring 44.

The latch 41 may be provided with a hook 52 (Figs. 5, '1, and 9), limiting angular movement of the latch member. For this purpose the support 35 is provided with a struck-up portion 53 around which the hook 52 extends.

A compression spring 42 (Fig. 1) is used to return the slide 38 to the position of Fig. 1 when the force on the casing I--22 is released. This spring abuts the vertical walls 43 of casing half I, and its other end abuts boss 4I A spring barrel 31 telescopically slides inside of slide 38, and is attached to the boss 4I. Its inner end carries a stop collar 36 adapted to contact the left-hand end of slide 38.

Upon release of casing half 22 from the position of Fig. 2, the spring 42 expands; collar 36 urges slide 38 to the right; racks 34 likewise move to the right; and pinions 32 rotate in a counterclockwise direction, closing cover 29. Pawl 21 rides over ratchet 26 and the lighter assumes genera-ily the position of Fig. l except for the relative positions of pawl 21 with respect to the teeth on wheel 26. Since the hairpin spring 44 is anchored to the latch 41 at a point below pivot pin 48 (Fig. '1), this spring urges the latch in a clockwise direction, so that it is caused to engage the edge 59. The device is now ready for another cycle of operations.

Since the lighter is held when used in the palm of the hand, it is easy to keep the flame shielded.
