GRIGrGS` MANUFACTURING CO., OF WATERBURY, CONNECTICUT, .A CORPORATION F CONNECTICUT l AUTOMATIC LIGHTER `Application inea February 15, 192s. seriaifN. 254,327.

Myinvention relates to improvements in automatic lighters, Aand more especially to those designed"` for `lighting cigars `and Cigarettes, wherein pyrophoric material and a friction member are employed to ignite a fuel-saturated wick, upon the opening of the lidor cover of the case containing these elements, the flamebeing extinguished when said cover is closed.` i

`The primary object of my `invention is to produce a lighter of this character which is `so formed or shaped that it can be carried `Another object is to provide the lighter "with a safety appliancewhereby is prevented danger of ignitio-nin the pocket and of any accidental ignition.` This is` an especially valuable feature, because it renders the lighter safe at practically all times.` i

A further 'object `is accomplished g by mounting on the same axis the lid or cover and lthe friction member, since thereby are obtained additional degrees of compactness and simplicity.` v i This lighter is attractive and lendsitself readily to the application thereto of an orna- `mental finish, owing to the shape and construction thereof. i

Other objects and advantages will :appear inthe course of the following descriptiom I attain the objects and secure the ad-` vantages of my invention by the means` il- `lustrated in the accompanying drawings, in

Figure 1 is a front elevation of an automatic lighter which embodies `a practical form of my invention, the cover being closed; Fig. 2, aside elevation of said lighter, with the cover closed; Fig. 3, a front elevation ofthe lighter, withV the cover open; Fig. 4, a central, vertical section through thelighter, taken on lines 4&4, looking in the direction of the associated arrow, in Fig. 3, lthe cover being open;` Fig. 5, a cross section through the lighter, taken on lines 5 5, looking down, in Fig. 1; Fig. 6, a side elevation and partial section of the upper portion of `a 'lighter which embodies a slight modification, and Fig. 7, a cross section on lines 7-7, Fig. 4, looking down. e e e Similar reference characters designate similar parts throughout the several views. The case of this lighter is preferably long and narrow or slim and generally cylindrical in type to enable the same to be carried con-` veniently in a pocket and to beheld therein by means of an ordinary pen or pencil clip applied tosaid case. `This case comprises a tubular .body 1 having bottom or floor members 3 and 6 respectively on lower and upper planes, a curved wall 8 between said bottom members, a top 9, a tubular holder 10 between the more elevatedbottom member and said top, and secured to the back side of said body, and a cylindrical holder` 11, for a wick 12, secured to the front of saidbody and to said top. The lower member or floor 3 is approximately coextensive ,in `area with the interior of the `bod 1, but the upper member Gis merely a fi ling piece that extendspart way around the lower end ofthelholder 10 between the upper end of the wall 8 and the back side of the bo'dy 1. Within the body 1 is a chamber 13 for a liquid fuel, as 14, `and the wick 12 extends downwardly from the holder 11 into saidchamber and intothe fuel therein.. The upper portion of the wick 12 passes through a vertical openingin and protrudes above the top of the holder` 11. The wick `functions in a similar manner to any vwick in a device of this character, `and when consumed is `replenished in the usual manner. The holder 10 has therein a longitudinal passage which opens through the bottom thereof` into a small chamber 15 in the body l, and at the upper end into the space above the top 9. The chamber 15 isformed by the bottom members 3 and 6, the lower end of the holder 10, and the wall 8, being open of the door 3 1s a tapped assage 18. A filling hole 19 is provide in t e floor 3 below thc chamber 13.

A closure or cap 20 is provided for the bottom of the body 1, and said cap has secured in the axial center thereof a screw 2l whichv is adapted to enter and enga e the threaded sides of the passage 18 in the oor 3. A packing disc 22 is laced in the cap 20 around the zo screw 21. T e cap 20 is shpped onto the body 1 from below and pressed upwardly until the screw 21 enters the passage 18, when said cap is rotated in the direction to cause said screw to rise in said passage until the g5 disc 22 is forced ti htly against the under side of the fioor 3. 'ie cap 20, when in place, entirely closes the lower termina-l of the body 1, including the open side of the chamber 15, and the disc 22 seals the filling opening 19 ao and prevents an of the fuel 14 from escaprlig' t erefrom. o escape of the fuel can now e place except by capillary attraction through the wick 12.

Upon inverting the body 1 and unscrewing and removing the cap 20 with the disc 22 access is had to the opening 19, and liquid fuel can then be poured into the chamber 13,

after which said cap is replaced.

In the passage in the holder 10, below the length of pyrophoric material 16 (which may be termed a sparkingv stick 1s a spiral Spring 23, below that in sai passage is a supporting rod 24 having in the axial centerv thereof ascrew-threaded opening 25 to receive the screw-threaded u per terminal of an adjusting rod 26. The rod 26 at the lower end is bent at right-angles to the main ortion of said rod, as represented at 27, to orm a foot to rest on the floor 3 and thereby retain saidrod and therod 24 in supporting relation to the spring 23. The spring 23 directly holds the sparking stick 16 against afriction member 28 (or 28') presently to be described which member is above said stick, and said spring causes said stick to be fed upwardly to said friction member as the stick wears away. The amount of force exerted by the sprin 23 on the stick 16 is regulated by screwing the rod 26 farther into the rod 24 to decrease the amount of force or pressure, because the distance between the stick and rod is thereby increased and the spring 'permitted to expand to a greater extent, and by screwing said first-named rod in the o posite direction to increase said pressure, ecause the distance between the upper rod and the stick is then decreased and the spring is compressed to a greater extent.

Upon removing the cap 20 from the body 1, access is had to the foot 27 which is then in the chamber 15, and the rod 26 is partially rotated, b means of said foot to enable the latter to c escend into or enter the notch 17, when said rod and the attached rod 24 can be drawn outwardly to enable said first-named rod to be screwed fartherinto or out of said second-named rod for adjustment pur oses, or the parts can be entirely removed an also the sprin" 23 when it is necessary to renew the sparklng stick. -While the bod 1 is inverted, the sparking stick is droppe into the now upper end ofthe passage 1n the holder 10, the spring 23 is introduced through said end, and the rod 24 is inserted therein. Next, by means of the rod 26, the parts are pushed along in the holder passage until the sparking stick comes into contact with the friction member, and then the rods are forced farther in the same direction, against the resiliency of said spring, until the foot 27 is in the chamber 15, when the smaller rod is partially rotated to locate said foot in supporting position relative to the floor 3. Finallythe cap 20 is slipped onto the body 1 and screwed into lace.

p Rising from the top 9 adjacent to the opposite sides thereof aretwo lugs 29 through which extends a horizontal rod or spindle 30. A lip 31 also rises from the top 9 at the back. The lip 31 is in the form of an arc centering on the axis of the spindle 30. A cover 32 is mounted on the rod and has a rear, arcuate part to fit over the lip 31. The sides of the cover 32 are outside of the lugs 29. On the inside of the cover 32 adjacent to the front side thereof is a recessed member 33 which forms an extinguisher. When the cover 32 is turned down onto the top 9 or closed, the extinguisher 33 is over the exposed part of the wick 12, and all of the parts above said top are inclosed within said cover augmented by the lip 31. A latch 34 extends forwardly and downwardly, or u wardly and forwardly, accordingly as sai cover be in closed or open position, from the edge of said cover adjacent to the place where the extinguisher 33 is located. There is a lu 35 on the inner side in the center of the latc 34 adjacent to the free end thereof.

The rod 30 extends directly over the spark ing stick 16, and the friction member 28 (or 28') is mounted on said rod. The friction member 28 is in the form of or comprises a serrated or toothed segment against which the stick 16 bears, and is provided with an arm 36, while the friction member 28 is in the form of or comprises a serrated disc .against which a similar stick bears. In each case the serrations or teeth are on the periphery of the friction member and always'in pothe rod 30 on both sides of the friction member 28, and crossed over below or in front of said arm, accordin to position ofthe arm, and has'its free en s bearing on the top 9 or on the top of thewick holder 11. Thus it is seen that the spring 38 tends constantly to actuate the arm 36 and the cover 32 upwardly, i

and to cause said'cover when released to open i forcibly and speedily. The opening movepart of the spring 38 bears against the top of the cover 32 inside of the same, and so serves the same purpose and operates in subtanti'ally the saine way as does the spring 38 in the first example.

A resilient pawl 39 has one terminal fastened at 40 to the top of the cover 32 inside of the saine, and the'other terminal arran ed to engage the teeth on the friction mem r 28', and is so positioned that it slips over the serrationson said member when said cover is closed the contact of the sparking stick 16 with said serrations then holding the member against rotation, but said pawl actuates said member on its axis when said cover is opened, with the saine velocity as that of the cover. The friction member 28 is held to the cover, so that it must move therewith, only when said cover is rocked or swung from closed to open position, the pawl 39 then being the holding agent.

Secured to the front of the body near the top thereof is a guard or keeper 41 compris ing a front and two side pieces, and within this keeper is a flat spring 42. There is a recess 43 in the keeper intermediate of .its top and bottom ends, and the upper portion of the front side of the keeper is cut away, as represented at 44. The spring 42 fits between tlie sides of the keeper 41, has its lower end riveted, as at 45, to the front of said keeper, extends upwardly be ond the bottom edge of the recess 44, and as therein ]ust above said edge a recess 46.

The upper terminal of thespring 42 is in the path of the latch lug 35, and, when the cover 32 is closed, said spring is actuated inwardly by said lug until the latter enters the opening 46, which it does as soon as the cover is seated on the top 9, said opemng being so located as to bring about this result. Thus the cover 32 is held in closed position over the wick 12 and the other parts and members on and above the top 9, and accidental release of the cover is prevented because the recess 44 now closed by the lower part of the latch 34, and access to the spring 42 can only be had through the notch 43 in the-keeper 41. However, upon placing the thumb nail against the exposed part of `the spring 42, throughv the notch 43, and press'- ing said spring inwardly, it is actuated out of yengagement with'th'e latch lug 35, and the spring 38 immediately acts forcibly to throw the .cover upwardly and rearwardly into open position, and at the'same time to cause the .friction member 28 (or 28') to move rapidly across the top of the sparking stick 16, with theresult that sparks are produced and the fuel with which the wick 12 is saturated is ignited. p f In practice, assumin that `die lighter he in readiness for use, an that the cover 32 is closed, the body 1 is held in one hand, and the latch 34 is released by pressing the spring 42 inwardly with the nail ofthe thumb orthat hand, when said cover flies open and the friction member 28 (or 28') is rapidly actuated over the contiguous end of the sparking stick 16. The sparks thus produced ignite the wick 12, and the ame from said wick is ap plied to the cigar or cigarette. In the closing operation, the cover is rocked forwardly and downwardlyon the rod 30 until the latch lug 35 enters the spring openin 46. Thecover 1n closing extinguishes the ame.

Generally the closing movement of the cover, and the movement imparted by lsaid cover-to the friction member 28 is so slow that no sparks are produced from the ignition stick 16 by the movement of said friction member, but, even if there were, they would be without effect because of the presence of the extinguisher 33 over the wickv12. In the case of the friction member 28', the pawl 39 clicks over the teeth of said member without rotating the same when the cover is closed, and the member does not, therefore, act on the sparking stick. The wear 'on the sparking stick from the friction member28pmay be a little less thanthat `on` the friction member 28, because the` former acts on the stick only when the cover is opened, while the latter acts on the stick when the cover is `closed as well as when it is opened, but such action coincidental with the closing operation is of a character that produces very little wear on the stick.

More or less change in the shape, size, construction, and `arrangement of `some or all of the parts of this lighter, in addition to thmose hereinbefore specifically pointed out, may be made without departing from the spirit of my invention, or exeeedingthe scope of what is claimed.
