This invention relates to a means for sealing the wrappers that are used for enclosing cigars. It is well known that'at the present time, there is a widespread tendency on the part of cigar manufacturers to the purchasin public a more sanitary product, by whol y wra ping or otherwise enclosing the cigars which they manufacture in a wrapper of some sort. Such wra pers are composed of various materials, suc as tinfoil and various kinds of transparent cellulose papers, one of this type being referred to by the trade name of Cellophane. This last mentioned transparent paper wrapper is so made that when thesame is wrapped.

around the cigar, its overlapiped edges, and its ends which project beyon the cigar tips,

may be sealed together by an application of,

sult of this contact is that the printing and varnish appearing on the band is softened by the heat, causing not only the band to be badly smeared and blurred in appearance, but creating an odor of scorched ink and varnish which is likely to be retained by the cigar, thus greatly deteriorating from its flavor and consequent value.

The object of my invention therefore, is to provi re a heat-applying means for sealing a cigar wrapper, in which said heat-applying means will avoid applying heat to any portion of the cigar band appearingon the cigar that is being wrappe whether such band actually forms a part of said wrapper or whether it is independent therefrom and encircles the cigar under or over the wrapper. In ci ar wrapping machines of the presentay type, the heating means for sealresent to I 1880. Serial No. 0,746.

ing the wrapper is usually'in a fixed position or so arranged that should the machine cease operation by reason of becomin clogged or should its operation be halted or any 0t er reason, the heat-applyin means will continue its application of cat to anycigar that happens to be located ad'acent to it or in contact with it in the mac ine. .The result of this is that said particular ci or or cigars located adjacent to it are spoi ed by becoming scorched or burnt.

A further object of this invention is therefore to remedy this defect in cigar-wrapping machines by arranging the heat-applying means so that the same may, during any period of cessation of operation of the machine, be. moved away from the cigars in the wrapping machine so that it is not possible for suficient heat to be applied to such cigars to dry out, scorch or otherwise cause such cigars to be injured.

With these'objects and such other objects as may hereinafter appear, in view, I have devised the arrangement of parts set forth below and more particularly pointed out in the claims appended hereto.

Reference is'to be had to the accompanying drawing, forming a part hereof, in which Figure 1 is a plan view of a wrapper composed of a transparent, glassine paper of similar characteristics as that known under the trade name 01'. Cellophane, which wrap- Figure 3 is a sectional view of a heat-applying means in the act of sealing the wrapper about a cigar;

Throughout the various views of the drawing, similar reference characters designate similar parts.

In the embodiment of my inventiondisclosed in the accom an ing drawing, 1 indicates a flat or unfo de wrapper a apted to enclose a cigar. The same may, as hereafter set forth, be made of any suitable material capable of bein sealed about a c gar by an a plication of heat, such-as for instance, a g amine type of paper of the kind commercially known as Cellophane. The wrapper 1 preferably consists of an elongated sheet of such material and in the embodiment shown in Figure 1, the same is provided with the representation of a cigar band 2 which is printed directly upon the sheet. Thus, the

erforms the dual function of enclosing the cigar and at the same time to all effects, providing a cigar band therefor. v

In Figure 2, the wra per 1 is shown as bein wrapped about a 01 ar 2' with its lon- 'tudinal side edges 3 an 4 laced in overfiipped relationship. In suc relationship, these edges are adapted to be adhesively secured together by an a plicati'on of heat. The means for applying eat and sealing the wrapper is disclosed in one of its embodiments at 5 in Figure 3. In such embodiment, the heat-applyin means consists of a member havin a shal ow top depression 6 shaped to fit the s ape of the cigar after the wrapper ends 7 and 8 have been compressed together by any suitable means. The member 5 may be made of metal or any other suitable substance and receives its heat from a heating coil 9 contained within it. The heatin coil is heated from any suitable source of e ectric current. It will be understood that heat may be applied to the heating member 5 by any other suitable heat-supplying means.

In order to prevent the member 5 from applying heat to the printed representation of the band 2 appearmg on the wrapper 1, I

rovide an aperture or recess 10 in the upper ace of the member 5, said aperture or recess being so located that the same lies in registration with the band.

Thus, when the member 5 is brought into contact with the wrapped cigar for the purpose of a plying heat and some slight ressure, to t e overlapped edges 3 and 4 o y the wrapper, the printed portion of the wrapper is insulated from, or held out of contact with the band or any other printed matter that might be placed on the wrapper. This prevents the varnished surface and printing of the band being blurred or smeared and incidentally avoids the creation of an odor caused by scorched varnish and ink that might possibly be absorbed and retained by the cigar.

The heating device 5 ma be supported in any particular manner suc as on a stem 11. Such stem is adapted to be reciprocated, as for instance, by'a segmental gear 12, engaging with a rack 13 secured on the stem 11. 7 The segmental gear 12 is pivoted on a stud 14 that may be provided on any suitable part of the wrapping machine and said gear is actuated by an arm 15 that is connected to a rod 16. The rod 16 may run to a suitable 7.

edal operated by the foot of the operator or shifting the heating means 5 away from the cigar when the machine is laced out of operation so that heat will not continually applied to any cigar then located in the mac me and caused to be scorched. Therod 16 may be also operated by cam and clutch means acting to automatically shift the heating means 5 away from the cigar during a cessation of operation of the machine. Such clutch means is customarily found on cigar wrapping machines of the present day type and the rod 16 can readily be connected up to it.

In Figure 5, I show a modification of the heating means wherein the same consists of two independent spaced lates 17 and 18 which are arranged apart rom one another so that they provide an aperture 19 between them. These plates 17 and 18 are heated in any suitable manner andare either movable so that they may be brought in contact with the wrapped cigar to seal the same, or the ci ar can be moved to be brought in contact with the plates. In either event, the wrapped cigar shown at 20 is so positioned with respect to the plates 17 and 18 that the cigar band 21 is located in registration with the a erture 19 and thus held from contact with t e face of the plates 17 and 18 and consemeans 5 providedwith a section of insulation 22 so located that the same lies in regis tration with a'cigar band 23 during the aplication of heat to the wrapper by the memr 5 in that figure. This insulation is sim-' ilar in result to the aperture 10 and it may be of porcelain or any suitable substance which 1 does not retain sufiicient heat to alfect the band or any other printed matter that might be either placed directly upon the wrapper 1 or else encircle the cigar under or else on the outside of the wrapper. 1

While I have herein shown, particularly in Fi ures 1 and 2, a ci ar band actually physica ly printed upon the transparent wrapper 1, it will be understood that the band may be of the ordinary kind wholly independent of 1 this wrapper, encircling the cigar either under or over the wrapper. In any event, it is found desirable to prevent heat from being applied to the band and thus my invention is applicable without regard to how the band is 1 held on the cigar. Thus, when I herein refer of said sheets by an application to a banded cigar, I wish to be understood as meaning any of the various ways described herein by which the band ma be applied.

In the structure shown in i re 6, where the heating means 5 is capable 0 being moved to and from the cigar, the cigar ma be supported in any suitable way during t e application of heat. I have diagrammatically shown, for this purpose, clips or grippers 24 acting to hold and support the cigar during the application of heat to its wrapper.

Having described several embodiments of my invention, it is obvious that-the same is not to be restricted thereto but is broad enough to cover all structures coming within the scope of the annexed claims.

What I claim is y 1.
