CHARLES B. LOVELESS, OF WORTHINGTON, MINNESOTA.

SMOKING-TUBE.

SPECIFICATION forming part of Letters Patent No. 273,294, dated March 6, 1883.

Application filed November 2B, 1882. (No model.) l

clear, and exact description of the same, refer! ence being had to the annexed drawings, making a part of this specilication, and to the letters and ligures of reference marked thereon.

Figure l of the drawings is a longitudinal vertical section of my invention; Fig. 2, a similar view of the tobacco cartridge or shell and spring-casing, Fig. 3, a cross-section through line fr x, Fig. l; and Fig. 4, a detail view, in perspective, of the tobacco cartridge or shell.

This invention relates that class of smokers7 tubes made in imitation of a cigar and having inserted therein an inner tube or cartridge conltaining the tobacco and a spring for automatically feeding the same to the end of the tube as tast as it is consumed.

Previous to my invention these springs were usuallyT exposed to the nicotine coming from the smoke, which would in time foul and clog them up. In'order to remedy this difficulty, a small tube or pipe was employed, which extended from the mouth-piece through the coils ofthe spring into the body of the tobacco, said tube or pipe having perforations at its outer closed* end, through which the smoke was drawn. The objection to this construction was the fouling of the tube as well as the clogging up of the perfor-ations at its outer end by the sweating and swelling of the tobacco when burning; and these perforations being necessarilyfew and small, owing to the size ofthe tube or pipe, such a smoking-tube has been found objectionable from the necessity of frequent cleaning to insure sufficient draft.

The objects of the present invention are to remedy the defects above described and provide such a smoking tube or article in which the fouling or clogging up of the parts is less liable, and from its simplicity of construction is readily and cheaply manufactured and more effective in its operation than articles of a like nature heretofore in use. These objects I attain by the construction substantially as shown in the accompanying drawings and hereinafter described.

In the drawings, A represents a tube made in imitation of a cigar, preferably of thin metal that may be spun or other otherwise formed in the shape desired, though said tube may be composed of any material found most suitable and inexpensive. In this tube A is placed a shell or cartridge, B, for containing the t0- bacco, said shell or cartridge fitting upon a casing, C, having within its interior a coiled sprin g, D, operating a follower, a, which forces the tobacco toward the outer end of the shell or cartridge as it is consumed. This shell or cartridge B has upon its outer end a wedgeshaped collar, E, provided with a series of per- .Y

forations, b, around its circumference, the wedge shape ofthe collar`insuring the snug fitting of the shell or cartridge in the tube 'A, which has a bore of greater diameter than said shell or cartridge to admit of the smoke being drawn through the perforations to the mouth of the smoker without coming in contact with the spring, thereby preventing the same from becoming foul and clogged up, and the said perforations being of sufficient number and size the draft is not materially affected by the sweating and swelling of the tobacco while burning. A second row or series of perforations, c, is made in the shell or cartridge,just back of the wedge-shaped collar E, in order to increase the draft, and should the perfo'rations in the wedge-shaped collar become clogged or stopped up from any cause the draft would not be entirely hindered or prevented. The

shell or cartridge B is also provided upon its outer end with an annular ange, d, which fits against the outer end of the tube A, to give a finished appearance and prevent the same from burning when constructed of iniiammable material. The opening of the tobacco cartridge or shell at its outer or lighting end is of less diameter than its bore, in order to form a seat, e, for the tobacco, and thus prevent the spring from expelling the entire contents when said cartridge is connected with the casing containing the spring.

By the construction above described it will be readily seen that the smoke is drawn through perforations in the tobacco cartridge or shell IOO 1. The tube A and casing C, eontuining eoiled spring D, operating follower a, in coinbinaltion with the tobacco cartridge or shell B, having the wedge-shaped collar E, with perforations b, substantially as and for the purpose specied.

2. Tile tube A, easing C, spring D, and follower a, in Combination with the tobacco cartridge or shell B, having ange d, and perfo rated wedge-shaped colla-r E, substantially as shown and described.

In testimony that I claim the above I have hereunto subscribed my 11eme in the presence ot' two witnesses.
