SMOKERS PETROL LIGHTER.

Application filed may 7, 1927, Serial No. 189,712, and in Great Britain March 2,1927.

This invention relates to smokers petrol lighters of the kind wherein the wick tube is surrounded by a perforated, tubular shield which, while admitting air through its apertures to the flame, tends to prevent the latter from being blown out by the wind, the shield being wide enough to admit between it and the tube a closing cap which normally covers 4 the latter. The object of the invention is to provide additional security against the flame being blown out and also to render the flamesteadier, and the invention consists essentially in forming the shield with louvred apertures 'as to effect a complete combustion of the carbon particles, to deflect the wind from the wickand guard the flame against being blown out. To enlarge the flame, moreover, and supply it with plenty of fuel, the wick tube is split longitudinally so as to partially expose the sides of the wick as well as the top of the same.

Fig. 8 is'a sectional View showing a still further modification.

The lighter is provided with a wick tube 0 which is split longitudinally into a plurality of claws between which the wick is exposed.-

Normally the wick tube is covered by a cap d g which is connected to a pivoted arm 6 whereby it can be turned into and out "of operative position. The wick-tube, and also the cap cl, when the latter is in closed position, are surrounded by a wind shield a provided with louvred air apertures b, the louvres being arranged so as to deflect the wind from the source of the flame and guard the latter against being blown out.

In order to circulate the petrol vapours emanating from the exposed portions of the wick along the tube a and divert them towards I A strong and. steady flame is obtained in this adapted, while feeding air into the flame so" the flame, the louvres are, according to the invention, arranged so as to causethe draught to sweep the whole interior of the shield. For this purpose the louvres are preferably directed towards the bottom of the shield so that the air current will pass across the wick tube in a downward sweep, as shown by arrows in Fig, 4, and carry the vapours towards the flame at the lee side of the shield.

manner. a

A good circulation of the vapours can also be effected by arranging the louvres, as shown in Figs. 6 and 7, so that the draughtwill enter at a tangent to the wick tube and sweep spirally-around the latter, as indicated by the arrows.

If a short wick tube is employed as shown in Fig. 8, the louvre plates may be set in an upward direction.

The shape of the apertures may be varied. The elongated apertures shown in Fig. 1 may be replaced by a larger number of short apertures, asshown in Fig. 5.

The shield is normally covered by a plate f which is carried by the cap 03 and which has an extension 9 covering the abrasive wheel h. 3

We claim:

1'. In a smokers petrol lighter of the character described, th e combination with a wick tube and aclosing cap for the same of a wind vided with apertures and with internal end. of the tube, said shield and louvres being spaced sufficiently from the tube to admit the closing cap.

2. Ina smokers lighter of the character described, the combination with a wick tube and aclosing cap for the same of a windshieldsurrounding the tube, said shield being provided with'apertures and with louvre plates internally bent ofl from said apertures so as to direct the wind towards the bottom of the shield, said shield and louvres being spaced sufficiently from the tube to admit the closing cap.

3. In a smokers lighter of the character de scribed, a wick tube which is split longitudinally so as to form a plurality of claws between which the wick is exposed, a closing cap for said tube, and a wind shield surrounding said tube and cap, said wind shield being provided with apertures and with internal louvres adapted to deflect the wind from the end of the wick tube:
