OF NORTH. ATTLEBORO, MASSACHUSETTSfA CORPORATION OF MASSACHUSETTS LIGHTER CONSTRUCTION Application filed December 13, 1928. Serial No. 325,746.

This invention relates to lighting devices loosely mounted a suitable abrasive wheel and more particularly to those in which a 12 and a pressed metal actuating member 13. wick is ignited by sparks from pyrophoric Pressing against the lower surface of the metal or other suitable sparking material. wheel 12 is a short cylindrical piece of pyro- One of the objects thereof is to provide a phoric metal 14 resting within a tube 15'expractical device of the above type of simple tending downwardly into the fuel tank and and durable construction and which is eflithis pyrophoric metal is urged toward the cient and dependable in action.

A tubular Referring now to the drawing in detail, shaft or sleeve 28 extends between the arms 49 there is shown a fuel tank 5 provided with :26 of the actuating member and this shaft is the customary filling of absorbent material supported by'a pin 29 which extends through and openings through which liquid fuel may the arms and fits within the hereof the shaft be poured when the tank is inverted. A so that the shaft is revoluble thereon. burner 6 is provided on the elongated top The snuff'er arm 18 is channel shaped and wall 7 of the tank and this contains an abforms a housing for the friction wheel and sorbent wick 8 which eittends into the tank other parts in the vicinity thereof when this in the usual manner. arm is in closed position. Depending cars 30 Formed upon the upper surface of the top are provided on the side walls 31 of this arm wall 7 are 'a pairof webs 9 and 10. Jourand these are journaled on the shaft 17.

\\ naled in these webs is a shaft 11 on which is Each of the side walls 31 of this arm is provided with an elongated slot as at 32 and the shaft 28 extends through these slots. Flanges as 33 may be provided along the longitudinal edges of the slots 32 to reinforce such edges and provide wider faces in contact with the shaft 28. Such flanges may be formed by striking up the metal of the side walls in the formation of the slots 32. The shaft 28 and the slots 32 form a pin and slot connection by means of which the snulfer arm is actuated by the member 13. The ability of the shaft 28 to revolve provides a roller action within the slots 32 which insures smooth and easy operation of the parts. A spring 34 acting against the snuffer arm normally retains the actuating member in raised position and causes the snuifer to press firmly on burner 6 in the manner-described. An end web as 35 between the webs 9 and 10 may be provided and this will act as a shield for the burner.

The eccentric action produced by the spac ing of the axes 11 and 17 provides a variable speed of rotation of the wheel 12, orin other words a snap action. The wheel rotates slowly as the cap is being raised clear of the wick, then rapidly to provide the shower of spark, and then more slowly as the finger piece approaches its lowest position. As no stop is present to limit the upward movement of the member 13, pressing contact of the snuff er and the burner is insured when the actuating member is released.

In the operation of the device the finger piece 25 is depressed from the normal position indicated in Fig. 1 to that shown in Fig. 2. The downward movement of the shaft 28 in this finger piece acting in the slots 32 causes the snufler arm 18 to swing about the axis of the shaft 17 into its raised position or substantially that shown in Fig.2. At the same time the ratchet arm 22 rotates the ratchet 16 one tooth distance or approximate- 1y 90 and carries with it the friction wheel 12, causing the teeth on the periphery of this wheel to act against the upper extremity of the pyrophoric metal 14. This projects a shower of-sparks upon the wick 8 of the burn- I er and lights the same. The parts will remain in this position and the lighter will continue to burn as long as the finger piece is held in its depressed position. -As soon as the finger piece is released the spring 34 causes the snuffer arm to return to its normal or lowered position over the burner, extinguishing the flame thereon. This movement of the snufier arm acts through the pin and slot connection to cause the actuating member'to swing upwar'dly to its raised position. At the same time the ratchet arm 22 is advanced on the ratchet 16 to engagement with the next tooth. The friction wheel 12 remains stationary during this return movement of the parts. This completes the cycle of operations and the parts are now in when desired.

position to repeat the samev It is obvious from the foregoing description that the lighter is simple and durable in construction and eflicient and dependable in action. The long leverage .provided by the member 13 greatly facilitates the operation of the device. The mounting of the snuffer arm on an axis further removed from, the burner than the axis of the frictionfwheel makes it possible to swing the snuffer a; considerable dfstance from the burner and thus not only prevents the snuifer from becoming tarnished by the flame but provides more available space about the burner which is advantageous particularly when a pipe is to be lighted. The pin and slot'connection enables the snufi'er to be readily lifted by the actuating member without the use of racks and piniofis or other gearing which in such a relation are liable to cause trouble and are generally the first parts of. the lighter to wear out. Furthermore this connection permits the replacement of the snufi'er on the burner as soon as the finger piece is released. Firm pressure of the snufler on the burner is always insured when the finger piece is not depressed.

It will thus be seen that there is provided a device in which the various objects of this invention are achieved and-that the same is well adapted to meet the hardest conditions of practical use.-

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood all matter hereinbefore set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
