CIGARETTE.

Specification of Letters Patent. Application filed June 18, 1911 Serial No. 832,826.

Patented Mar. 19, 1912.

To all whom it may concern:

-Be it known that I, Bnz H. WHITMORE, a citizen of the United States of America, residing in-New York, borough of Brooklyn,.county and State of New York, have invented certain new and useful Improvements in Cigarettes, of which. the following is a specification.

This invention relates to cigarettes, and more particularly to those which are made of a filling of tobacco, finely cut, surrounded by an inclosing envelop. And further, to Igigarettes made of material which will'not urn.

Hitherto cigarettes have been made by wrappin tobacco in paper and mostly in the so-ca ed rice paper, but objections to the generally made by reason of the fact that the smoking of suchv ci arettes is accompanied by the poisonous an deleterious nicotin and other oisons which, it is claimed, have their objectionable features aggravated b the burning of the rice paper. Also, hit erto, means have been proposed to obviate the necessity of this rice pa r, but these means have proven unsuccessfu in that such means consisted of asbestos paper, the object of -bestos fibers and c othfibers.

which was to provide an unburnable wrapper.

These cigarettes made of asbestos paper have not proven successful and indeed have been discarded, for the reason that the asbestos aper'is composed of as- Thus on the smoking of the cigarette the ignited tobacco will cause the asbestos to be heated to such an extent as to burn out the cloth fibers in the asbestosiplaper container. This burning of the cloth bers, whichis an organic substance, results in the formation of gases, unpleasant and injurious. These gases are inhaled with the tobacco smoke and condensed on the walls of the lungs. A further objection to the paer cigarettes hitherto used was that the ashes would breakoff at times not desired, and a further objection of the asbestos paper cigarettes was that by reason of the stiffness of the same it was impossible to properly break off the burnt part of the same when it was desired to remove the ashes. In cons uence thereof the cigarette necessarily lost its character as a y invention has for its object to do away with the objection-able features ofthe paper and asbestos paper coverings for cigarettes the ignited portion has free communication with the exterior of the casing throughout the length of the same and continuously during the burning of the' tobacco from the tip of the cigarette to the end of the same. This mode of operation is obtained by preparing the wrapper of ver finely'divided asbestos fibers and binding tiie same together by a substance, such as starch and water, whichacts as a binder to hold the finely divided asbestos threads together, and which are so constituted that onthe burni jof the cigarette the starch is'so convert g not to impede the flow ofair through the interstices or cells between the several fibers of asbestos, by reason of which a free communication is maintained between the inner part of the cigarette and the outer part of the same continuously ,throughout the length of it as the tobacco burns. This cigarette has the great advanttige that it is impervious to airwhile containing the unburned tobacco and pervious to air after the covering has been subjected to the heat of the burning tobacco. Since the ashes occupy a smaller space'than the tobacco, a canal erable space is left for air to enter. And in the presence of this open space, air Wlll not enter through the pores. The use of the cigarette is unaccompanied by any objectionable burning odors.

In the improved cigarette proposed the starch being converted by heat, no gases or smoke are added to the smoke of the tobacco itself, and thereforeit is possible by this proposed means to have all the advantages of cigarette smoking. Furthermore, the porosity of the wrapper during the time that it is being subjected to heat, provides an absorber of the poisons, such as nicotin, etc. 7 v

A further object of my invention is to so arran e the wrapper as to permit the breaking 0 of the burnt parts as the ci arette burns, and for this purpose I special y prepare the asbestos wra per of such'thmness that itrmay be torn 0 at the desired point, and only at the oint where the burning takes place and on y on a positive severance.

' This operation differs from the usual asbestos paper cigarette in that it is capable of being really severed when desired, and from materials employed. The action of the heat on the starch and thinness of the wrapper, momentarily suspend the cohering action of ,the parts while under the immedlate action of heat,- the parts of the wrapper inwardly of this heat zone and the parts outwardly of the heat zone having substantially their normal cohering qualities. By. this propnerty it is possible to sever the wrapper at "the part immediately under the action of the heat, and obtain thereby the advantages of the ordinary cigarette. 1

In the accompanying drawing is shown in Figure 1 a perspective View of my improved cigarette and inFig. 2 another view showing unconsumed tobacco, the parts being s own the severanceof the part'inclosing the consumed tobacco from the part inclosin the .in approximate size only, in view of the difiiculty of accurately depicting exactly the thinness of the wrapper.

lhe asbestos covering 10 surrounds the tobacco 11 and is severed at 12 where the tobaccois burnin while the severed wra per 13 surrounds tie ashes 14 resulting rom the burning of the tobacco. A cork tip 15 maiy be provided if desired.

claim as new and desire to secure by Letters Patent:

A cigarette consisting of a' wrapper of asbestos fibers finely ground and starch inti- -mately mixed together and a filling of towrapper cooperating in such abacco, said manner wlth the lgnlted tobacco that c0ntmuous and lntlmate communication is maintained between the ignited tobacco inthe inner part of the wrapper and the atmosphere exterior to the wrapper.

In testimony that I claim the foregoing as ,my invention, 1 have signed my name in presence of two subscribing witnesses.
