This invention relates in general to' `improvements in pocket lightersl of the pyro.

phoric e. Y y e One of the objects of this inventlon is the 5 provision of a pocket lighter involving the principles of construction whereby eliiciepcy of operation and simplicity of construction are assured.

Another object of this invention is the pro-` vision in a ocket lighterof this type of a structure w ich requires but a single motion to uncover the wick and create sparksto ignite the vapors given off by the wick. A further object of this inventionis the .15 provision in a llghter of this type of a con.-

struction by means of which the snulfer is automatically returned to cover up the wick when the ressure thereon is relieved.

A still rther object of this invention is the provision of a snuifer arm construction v operatively associated with a flint wheel so that upon movement of the snuer arm to` uncover the wick the iiint wheel operates to produce a spark from the pyrophoric material and in the reverse movement of the by means of this invention.

rlhis invention resides substantially in the .combination, construction, arrangement and` relative location of parts, all as will be described in greater detail below.

Referring tothe drawing- Figure 1 is a vertical cross sectional view through the lighter of this invention; y

Fig. 2 is a cross sectional view of the upper part of the lighter taken on the line 2-,2 of Fig.1; Y f Fig. 3 is a cross sectional view taken on the line 3 3 of Fig. 2;

Fig`. 4 is an elevational view of the upper part of the lighter showin the relation of the ratchet wheels, flint w eel, and snuer arm; l Fig. 5 is an enlarged side elevational view showingthe position of the' snufer arm with respect to its supports when pressure is applied thereto and it begins to rise;

tion and its operation will best be understood by reference to the 'drawing in detail. At 1 is shown the container for holding the absorbent material 7 and the volatile fuel commonly used in such lighter. This casing is provided with a threaded opening to receive o the plug 2 through which the fuel is intro-` duced tothe interior of the container. The top of the container is shown at 4 and below it is the upper wall orpartition 3 of the container 1. The top4 wall 4 is cut out at the w4 center to provide a cavity below the upper end wall of the casing. The casing is provided with a wick tube 5 through which the wick 6 of the usual type projects. Extending upg wardly through the container 1 is the tu 8 which-is closed by means of an adjustable threaded plug 9. Egtending from the upper end of the tube 8 is the pyrophoric material 11 which is urged upwardly by a spring 10 L -which lies between it and the adjustable plug 9. Mounted on the top of wall 4 are two brackets 12 in which. is mounted Athe hollow central spindle 13. A small pin 14 extends through the tube 13 and is peened over at the ends to hold the parts in operative rela-A so gtion. Encircling the pin 14 is a spring 15v which has one end secured in a-notch in the end of the tube 13 as shown at 15a in Fig. 6.

The tube 13 is cut away, as shown at 13a for a short distance and the other end 15b of the spring extends therethrough.

Mounted on the tube 13 for rotation is the usual ii'nt wheel 17. Also mounted on the tube 13 for rotation thereon is a cap member 18 which covers all the parts and comprises ,0l

what might be called the snufer arm. Mounted within this cap 18 is t snuii'er member 29 which fits down over t e wick to put outl the ame and prevent evaporation of fuel when the device is'not in use. At the point formed in the cap18 by cutting away a poif-l 100 wick tube. .The spring also acts to hold the cap upwardly, that is so that the lower end of slot 16 comes to the bottom of the tube 13. Also mounted on the tube 13 and secured in any suitable manner to the flint wheel and on each side thereof are the ratchet wheels 19.

Thus the ratchet wheels and flint wheel rotate as a unit on the flint tube 13'. As clearly shown in the drawing the cap 18 has formed on the interior thereof and in line with the ratchet wheels two pins 20.

In the normal position of the parts the snufi'er arm 18 as described is in the position shown in Figs. 1 and 3 with the snufier member 29 contacting ,with the wick tube 5 and 20'- the cap 18'held upwardly by the spring 15, as

shown. In operating the lighter, pressure is first applied to the top of cap 18 and as a result it moves downwardly, in the position shown in Fig. 5 for example, so ,that the top of the tube 13 contacts with the top end of slot 16. In other words, the cap 18 has a sliding vertical movement by reason of the slots'16 on the tube 13 and the first pressure thereon forces the cap downwardly. This 30" downward movement of the cap causes the fpins 20 to move into engagement with the ratchets 19, as is clear for example in Fig. 5. Backward pressure is then imparted to the y v cap 18 causing it to rotate in a clockwise direction, as indicated in Fig. 5, and carrying wi'thfit ratchet wheels 19 and flint wheel 17. As the flint wheel 17 moves across the'top of the pyrophoric material 11 sparks are prod duced which are thrown against the end of 40 wick 6 causing the vapors given off thereby to be lighted. Hence with a single movement of the thumb the cap and snuffer, which together comprise the snuiier arm, move upwardly exposing the wick and at the same 4s time the flint wheel is rotated to produce -During the movesparks to ignite the vapor. ment of cap 18 spring 15 is put under tension so that when the cap is relieved of pressure the spring throws it back into closed position, as shown for example in Fig. 1. At

the beginning of this return movement of the cap the first thing that happens is that the -spring throws the cap upwardly on the tube 13 and then the cap is given rotary motion in a counter-clockwise direction to close it and snuff out the flame. A

From the above description it will be apparent that we have devised an exceedingly simple structure in a pocket cigar and cigarette lighter in 'which the entire exposing the wick, producing operation 'of sparks, and igniting the vapor is all carried out with a s1ngleoperation, namelyeffecting the movement of the cap, ashas been described. AIt T05 will be apparent, of course, that we have embodied certain princi les of construction and operation in one p ysical form as set` forth in the drawing for the purpose of illustrating these principles but we do not desire to be strictly limited to the physical form depicted butto any mechanical structure within these principles as defined in the appended claims.
