To all whom itmag concern:

Be it known that I, JOHN F. KNAPP, a citizen of the United States, and a resident of San Jose," county of ,Santa Clara, and State of California, have invented new and useful Improvements in. a Fire-Safe Qigarette, of which the following is a specificae tion'.

This invention relates to cigarettes and -has for its object a means for controlling the fire in a cigarette so as to insure its extinguishment at an predetermined point or provide for immediate extinguishment.

Briefl describedmy inventioncomprises the com ination of a common cigarette with a single tubular band slidab'ly mounted thereon, and made of a material s'ufliciently resistant to the fire of a cigaretteso as to extinguish the same when the band is slid to project over the burning end, or when the burning end reaches a polnt within the band.

In the drawings hereto illustrating my invention, Figure 1 shows a common cigarette with my fire control band in theposition it would occupy when the cigarette is sold. Figure 2 is an end view of Figure 1. Figure 3 shows the band slid, outwardly over the burning end of the cigarette so as to shut off the air circulation and thus cause speedly extinguishment of the fire.

Figure 4 shows the projecting end of the sleeve being pinched by the fingers of the smoker to cause immediate extinguishment.

Figure 5 shows the ci arette as having burned from the dotted orward extension down to the dotted line within the sleeve and there extinguished through lack of air.

In the drawings-the cigarette comprises its paper wrapper 1 and tobacco filler 2 and slidably mounted upon the cigarette is a single sleeve 3.

This sleeve is relatively long measuring in length about three times the diameter of the cigaretteand it may be of relatively strong fire resistant paper or it may be of metal or other material, tho paper is preferred as yielding more to the form of the cigarette Whether the same be of round or oval section, and friotionally remaining in any position along the cigarette.

The normal position of the sleeve when furnished on cigarettes is as shown in Figure 1 somewhat closer to the mouth end exposing the name 4 of the cigarette as printfire will then continue unti the ci e d upon the wrapper or which may if desiredbe printed "upon the sleeve.

If the cigarette is shown in Figure 1 is hghted at the left hand end it will burn freely to a point within the sleeve 3 and will then 0 out, owing to lack of air circulat1on,t o if it is desired the sleeve ma be slid to project beyond the right or mout end of thecigarette as shown in Fi re 5 and the rette has been consumed to about the dotte line 5 before it goes out;

On the other hand if the cigarette has just been started and it is desired to lay it down upon a table or drop it into-the pocket without danger of scorching the same, the sleeve may be slid forward over the burning end 6 as shown in Figure 3 thus making it safe against spreading fire'to surroundln material, and insuring its goin out, tho 1f desired to extinguish it immediately the sleeve affords a safe grip for pinching over the burning end 6 as indicated in Figure 4.

My special slidable sleeve as described will therefore be seen to provide a positive control for the fire in a cigarette with consequent elimination of the present danger of spreadin fire through discarded cigarettes, for the and in providing for smothering or pinching the fire without injury or trouble to the user will insure the fire being put out upon throwin away a cigarette equiped therewith, tho i the hand is not slid over the fire or pinched, the fire being usually close to the band will speedily go out aut0- matically.

In addition to the featureof fire rotection, other advantages are obtaine from the use of this band, such as economy, comfort, and convenience. A lighted cigarette can be easily extinguished and left in such condition that it can'be used again. The smoke from a ci arette can be instantl shut off so that the cigarette may be held in the mouth or set down without smoke arising to burn the eyes or throat, or defile the atmosphere. The band can also be used for a finger-hold, preventing stain, or as a mouthpiece.

In considering the above .invention it should not be confused with cigar bands or other bands as heretofore proposed,,for a cigar band will not. function to put out a V cigar as it may be smoked clearithrough one while usuall burnin the same in two, nor will very s ort ban s accomplish the desired result event if otherwise adapted to resist the fire, as it requires a comblnation of pro er length together with hysical adaptabi ity in order to make the evice practicable, and. when so made constitutes a valuable improvement in effecting the advantages enumerated.

of relatively heavy paper adapted. toresist hurning when projected over the fire of the hghted cigarette.

JOHN F.- KNAPP.
