This invention relates to cigars and cigarettes. One of the objections to smoking is due to the falling of ashes from cigars and cigarettes upon clothing, tables, desks, rugs, furniture, floors, etc., particularly from lighted cigars and cigarettes, creating an unsightly appearance and with some danger fromfire. Live ashes from cigars and cigarettes frequently fall on the clothing of the smoker, or upon rugs or upholstery, and burn holes therein. Ash trays are not always conveniently accessible to the smoker, and some smokers are careless about ashes from cigars and cigarettes and let them fall where they may.
One object of this invention is to provide an improved cigar or cigarette which, when smoked, will have increased adhesion between the ash particles on the burned ends thereof, so as to decrease the likelihood of the ashes falling 01f unintentionally; with which the tendency of the ash particles to adhere to one another and to the unburned portion of the cigar or cigarette may be increased or decreased as desired; with which the cost of the cigar or cigarette will not be materially increased; which cigars and cigarettes will have the normal appearance and smoking properties of the ordinary cigarettes and cigars; which will not be harmful or annoying to the smoker; which may be manufactured by the usual processes; and which will be relatively simple and inexpensive.
Another object of the invention is to provide improved cigars and cigarettes with which danger of injury by fire to the smokers clothes and to upholstery and rugs from falling ashes will be lessened; with which the normal draft of the cigar or cigarette will not be materially decreased; with which the-flavors and aromas in the cigars and cigarettes will not be materially lessened or modified; with which increased adherence of the ash particles to one another and to the unsmoked portion will be obtained, and with which danger of fire from discarded buttswill be lessened.
Various other objects and advantages will be apparent from the following description of several embodiments of the inventiomand the novel features will be particularly pointed out hereinafter in connection with the appended claims.

I Fig. 9 is a diagrammatic illustration illustrating how the glass wool fibers in the form of yarn or webs can be incorporated in the body of the cigarette while the cigarette is being formed by a continuous process.
Referring first to Figs. 1 and 2, the cigarette I there illustrated includes a rolled paper or wrapper l0 having a mass H of tobacco rolled or incorporated therein as usual in cigarettes, and also having incorporated therein a plurality of very fine glass, vitreous or similar non-combustible, synthetic, mineral wool fibers l2 which preferably progress in a direction from end to end of the tobacco mass. These synthetic mineral wool fibers may also be designated as synthetic ceramic fibers or synthetic siliceous fibers, and include rock wool made from natural mined mineral, slag wool made from blast furnace slag and glass wool made from refined batch materials of the type commonly used in glass manufacture. The glass or similar synthetic minerals, ceramic or siliceous wool fibers are usually most conveniently incorporated in the tobacco mass 'while in the form of webs or yarns in which the fibers are assembled rather loosely in groups, the web type being shown in Fig. 2, and the yarn type being shown in Fig. 3. The wool fibers are very minute in diameter and are usually smaller than rayon, silk and cotton threads commonly used in fabrics, and considerably smaller than human head hair. They are usually smaller than .001 inch in diameter and are preferably less than approximately .0007 inch 'in average diameter, and'may be as small as or even smaller than .0003 inch average diameter. The finer the fibers, the softer and more harmless they are, even if taken into the mouth of the smoker.
The fibers are somewhat flexible and most conveniently handled as small webs or yarns in which the fibers are somewhat loosely assembled. For example, such glass or vitreous wool fibers mass of tobacco.
may be drawn in fluid form from a small crucible with the aid of steam and disposed on a moving conveyor belt in the form of a delicate web. Such webs may be compacted into yarns if desired, and as such incorporated into the body or mass of the tobacco of a cigar or cigarette. The fibers may be slightly twisted or compacted sufiiciently to cause adherence between the same, but preferably they are not tightly twisted as into threads. These wool fibers do not have to be distributed uniformly throughout the mass but preferably they should be incorporated or interspersed at intervals throughout the mass. By increasing the number of non-combustible loose fibers in the cigar or cigarette, the greater the bond holding the ashes to ether and to the unburned portion of the cigar or cigarette. In Fig. 3 the fibers are more in the form of a yarn, with closer assembly or grouping of the fibers and with more space between the groups, and in both Figs. 2 and 3 some of the wool fibers are preferably arranged in the peripheral zone.
In Figs. 4 and 5 some I! are adherently secured to one face of a sheet or section of paper H in which the tobacco is rolled, so that by rolling tobacco in such a sheet the glass wool fibers will be distributed around the cylindrical mass of tobacco. The fibers i3 may be secured to the inner face of the paper which is to abut the tobacco, and more or less fibers may be used, depending upon the bond to be desired on the ashes. In Fig. 6 I have illustrated how the synthetic mineral, ceramic or siliceous wool fibers may be incorporated in the paper itself to facilitate handling. In such a case. the glass wool fibers are either incorporated in the pulp before it is formed into the web as in paper making, or the glass wool fibers may be deposited on a freshly formed and still moist and soft web and rolled or calendered into the face of the web sufilcieritly to cause them to adhere thereto.
In Fig. 'l I have illustrated in perspective and diagrammatically, one manner of forming the cigarettes in a continuous strip by rolling the paper strip, such as in Fig. 4, progressively around a mass of finely divided tobacco.
In Fig. 8 I have illustrated a modification of the cigarette shown in Figs. 1 to 3, and in this modification the cigarette is provided intermediate of its ends with a glass or vitreous wool stop or plug l5 which abuts against one end of the This plug may extend entirely to the adjacent end of the cigarette so as to act not only as a fire barrier, but also as a porous filter through which the smoke is drawn when the cigarette is smoked. If desired, the space between the stop or plug i6 and the adjacent end of the cigarette may be filled with a mass l6 of cotton or vegetable fibers or a mixture of the same with glass wool fibers. It will be understood that the barrier or plug IE will act as a fire stop, even though the space in the cigarette at the opposite side of the plug from the tobacco is of combustible material. The tobacco mass may have the non-combustible wool fibers incorporated therein, the same asin Figs. 1 to 3.
This stop or plug i5 is a porous, non-combustible fire barrier beyond which the cigarette will not burn by its own action. Most cigarettes, unlike cigars, ordinarily continue to burn after actual smoking ceases, and must be extinguished when they have burned to the part normally'held in the mouth or when the smoker is through smoking. Many persons toss such burning cigaof the glass wool fibers with them.
rette butts upon the highways and into waste baskets and the like, and they are a fire hazard wherever they are tossed. If ash trays are not convenient, the burning butt should be extinguished before it is discarded. By having these fire barriers or plugs l5 intermediate of the ends of the cigarettes, at about the points where the cigarettes are burning when normally discarded, the barriers will limit burning automatically and cause extinguishment of the butt before the burning proceeds far enough to burn the fingers, so that the butt may then be safely discarded without danger of causing a fire. If the cigarette, after being ignited, is tossed away before the burning tobacco reaches the barrier, the burning will only continue until it reaches the barrier, which materially decreases the fire hazard. If cigarettes are made with such non-combustible barriers, the fire hazards both indoors and out from discarded, but burning, butts would be decreased, since it would then not be necessary to discard the butt until it was dead.
In Fig. 91 have illustrated diagrammatically how the glass wool fibers may be incorporated in the interior of themass of tobacco progressively, as the paper is rolled progressively around a mass of tobacco. The sheet [1 of paper is rolled progressively as the paper is fed along, and streams of fine tobacco l8 and ID are deposited in succession upon the sheet just before it is rolled within the paper strip. These streams of tobacco may be deposited on the paper at the desired points, such as from spaced spouts 20, and be tween these spouts 20 I may feed the web or yarn 2i of glass or vitreous wool fibers which may pass around a guide or roller 22 and then along and slightly spaced from the paper, so that the second stream of tobacco l8 will be superimposed upon the web or yarn 2| of tobacco. In this form, as the paper i1 is fed along in fiat condition, first one stream IQ of the fine tobacco is fed on to the paper continuously, and then as the paper and tobacco move along they pick up the glass wool yarn or web 2! and carry it along Then another stream i8 of tobacco is deposited on the web, after which the paper ii is rolled about the tobacco and web or yarn to complete the cigarette. This may be done progressively for long strips, and then the strip cut into the desired sizesv for individual cigarettes. Obviously by depositing any desired number of tobacco streams, and feeding more webs or yarns of the glass wool fibers between the successive charges of tobacco, greater distribution of the fibers throughout the mass may be obtained.
It is also possible to thread the fibers as yarn by a needle through the cigarette from end to end so as to draw through the mass of tobacco any desired number of stretches of glass wool yarn or webs. Various other ways in which the glass wool fibers may be incorporated in the mass will appear to those familiar with the art or cigar and cigarette making. but those illustrated and described herein will illustrate some of the many different ways that the fibers may be incorporated in the tobacco.
In the case of cigars, the glass wool webs and yarns may be deposited fiat upon the tobacco leaves or interspersed between the leaves, before they are rolled into the cigar, and thus in both cigarettes and cigars the wool fibers will be incorporated in and interspersed throughout the mass of tobacco. When a cigar or cigarette having the wool fibers interspersed therethrough is smoked. the fibers a they are heated by the burning tobacco appear to act like tentacles and bend over and bind the ash particlestogether and to the unsmoked body of the cigar or cigarette and to have sufilcient strength to confine the ashes or bond them together and to the unburned portion of the tobacco so that the cigar or cigarette may be moved about in the normal manner. If suillcient fibers are incorporated in a cigarette, for example, substantially the whole cigarette may be smoked with all of the ashes remaining on the end of the cigarette, even though the cigarette is moved about as usual in smoking, yet with both cigars and cigarettes so made, if one desires to knock ofl the ashes, this may be done in the usual manner by striking the burned end or ashes against a surface or object.
With cigars or cigarettes formed with the wool fibers therein, the fibers are so minute and flexible that they are perfectly harmless to the smoker, even if taken into the mouth, and they do .not irritate or scratch the tongue or lips of the smoker and are almost invisible in the tobacco mass. They are-shown in the drawing on an exaggerated scale to illustrate the principle, but actually they are almost invisible in the tobacco mass, yet they are efiective in binding ashes together and to the unburned portion of the cigar or cigarette. The fibers in the ash portion are also substantially invisible. A singlestretch of a glass wool yarn through the center of a cigarette is fairly effective in binding the ashes together and preventing them from dropping off unintentionally, but better results are obtained if several stretches or lengths of the yarn or webbing are incorporated in a cigar or cigarette. The fibers oi the yarn or webbing of the wool appear to fuse Just enough to be brittle and enable the ashes to be broken oil when desired, yet to have sumcient strength to bind the. ashes together, and to the unsmoked body of the tobacco.
The fibers of the wool are preferably formed from chemically pure glass, so as not to contain impurities that will have any deleterious efi'ects on the smoker, but'various other similar non-combustible fibers such as mineral or vitreous wool fibers may be employed within the broadest principle oi the invention. Hence, when referring to glass wool, it will be understood that I consider various synthetic mineral wools or synthetic ceramic or siliceous fibers to be the equivalent broadly of glass wool, but I prefer glass wool because of the (act that the ingredients may be carefully selected and controlled, with less danger of contamination through impurities.
It will be understood that various changes in the details and materials, and in the different arrangements of the fibers, which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention, as expressed in the appended claims.
