METHOD OF WAXING PAPER.

srnorn'zcnrron forming part of Letters Patent No. 286,403, dated October 9, 1883.

Application filed September 10,1883. (No model! In all whom it may concern.-

Be it known that 1, JAMES B. DUKE, a citizen of the U nited States, residing at Durham, in the county of Durham andState of North Carolina, have invented new and useful Imuse for cigarettes is so light of texture and so extremely delicate in texture that it is readily disintegrated and broken down by the action I vof the saliva, causing awaste of the tobacco in the filler, which is left in the mouth of the smoker. Various means have been devised to avoid this difficulty, such as coating or sat-urating the paper with an impervious and neutral substahce-such as wax or parafline, and other substances-and it is the purpose of my invention to provide a novel and simple method whereby the cigarette-wrapper, or the sheet from which the wrappers are out,

, may be treated for the purpose of applying thereto a coating of the kind described.

To this end therefore my invention consists in a novel method. of applying to the end or ends of cigarette-wrappeis a moisture-proof coating, consisting of melted waX or parafiiue, or other equivalent material, whereby an impervious and insoluble coating is imparted to the paper.

The drawings hereto annexed show one form of apparatus by which I may carry out my in vention, and in said drawings Figure 1 is a plan view. Fig. 2 is a side elevation. Fig. 3 is a transverse section. Fig. 4 is a view of a cigarette-wrapper after it has been treatedhy my method.

A in said drawings designates a coil or equivalent arrangement of steam-pipes of suitable form and dimensions, the pipes being arranged side by side in the horizontal plane. Resting upon this coil is a pan or similar vessel, B, adapted to contain paraffine, white wax, or an equivalent substance, which is kept in a fluid condition by the heat derived from the coil.

i Mounted upon a section of the steam-pipe A, which extends in front or at one side of the trough, is a metallic sleeve, 0, preferably made of metal having a high conducting-power. The upper face of this sleeve is flattened, as shown at D, a .rib or feather, (2, formed upon the rear side, rising above the flat surface B, and a groove or channel, 0, being out along its opposite edge, as shown in the sectional view, Fig. 3, leaving a sharp angle, f, which bounds the surface B in front.

In the wall of the pan B, near its bottom line, is placed an outlet-cock, 1*], of any suit able form, and below the same is placeda con ductor, F, having its'discharge end just above the surface 1). This device may be arranged near one end of said surface, in which case the pipe-section should be slightly inclined. A dllP-CUP,Gr, is placed beneath the sleeve C.

With this form of apparatus my method is practiced in the following manner: By opening the cock E a limited flow of the melted paraffine or wax is p ermit-t-ed, which, by means of the conductor F, passes slowly to the fiat surface 1), the rib d aftbrding a gage, which fixes and equalizes the portion of the wrapper treated. The hot melted wax or paraffine is immediately absorbed by the paper, and solidi iies immediately upon removal, leaving a colorless, fiexible, and perfectly neutral coating upon the end of the wrapper, the edge f serving to limit the application of the paraffine, and to give a straight clean cut line of demarcation between the coated and the uncoated portions.

It is evident that an entire sheet of paper may be treated by this method and afterward cut up into wrappers.

I make no claim, in the present case, upon the apparatus shown and described, as that forms the subject of a separate application.

It is evident, moreover, that the method described can be practiced with other forms of apparatus. For example, the sleeve 0 may be dispensed with, and in place thereof I may use a plate heated by any suitable means. The vessel B also may be heated in a variety of ways, and the conductor F may be of any length within practical limits.

Both ends of the cigarette-wrapper may, if desired, be coated in the manner set forth.

Having thus described my invention, what I claim is 1. The method herein described of preparing the end or ends of a cigarette-wrapper to prevent it from being dissolved and broken down by the lips, said method consisting in diffusing melted paraffine or wax upon a heated metallic surface, having a suitable gage, and laying the end of the wrapper, or the edge of the sheet upon said surface, and immediately removing it and allowing the adherent mate rial to cool, substantially as described.

2. The method set forth of applying melted wax, paraffine, and similar substances to the end or ends of a cigarettewrapper, or the edges of a sheet, said method consisting in melting paraffine or wax in a suitable vessel,
