VENTED CIGARETTE HOLDER Filed March 2, 1964 11 J A/ /z W j QMWZQE United States Patent 3,265,074 VENTED CIGARETTE HOLDER Francis W. Davis, 90 Common St., Belmont, Mass. Filed Mar. 2, 1964, Ser. No. 348,483 1 Claim. (Cl. 131198) This invention relates to a cigarette holder which is vented to mix a controlled proportion of air with the smoke Which is drawn through the holder. Several advantages result from such a dilution of the smoke from the cigarette in the holder. The actual quantity of the smoke drawn into the mouth is reduced, thus lessening the toxic eifect of the smoke. The air has a cooling eflect on the smoke, with the result that the smoke mixture drawn into the mouth is lighter and pleasanter than undiluted smoke. For health reasons, physicians often advise patients to cut down on their smoking. Where a certain number of cigarettes per day has become a fixed habit, such a reduction is often diflicult to accomplish. By mixing the smoke with air, the desired reduction can be obtained without otherwise changing the established smoking habit. Attempts to realize these objectives have resulted in a number of patents showing various devices.

In ventilating smoke firom a cigarette, it is desirable that the degree of dilution be constant and that it be ad justable to suit difierent requirements. An object of the present invention is to provide a cigarette holder which can be easily made by a small modification of a holder now on the market, the modified holder being readily adjustable to dilute the smoke by different constant amounts. This is done by the provision of a collar rotatively adjustable to move any one of a number of vent holes of different diameters into operative position and to lock the collar in any adjusted position.

For a more complete understanding of the invention, references may be had to the following description thereof, and to the drawing, of which FIGURE 1 is a perspective view of a vented cigarette holder embodying the invention;

FIGURE 2 is an exploded elevational view of the same on a larger scale, both ends being broken off;

FIGURE 3 is a fragmentary elevation, on a still larger scale, of the parts shown in FIGURE 2, partly broken away to show in section;

FIGURE 4 is a section on the line 4-4 of FIGURE 3;

'FIGURE 5 is a perspective view of the collar shown in FIGURE 4; and

FIGURE 6 is an elevational view, similar to FIGURE 3, of a modified form of the invention.

The vented holder illustrated on the drawing can be easily and economically made by minor alterations in a holder now on the market. That' holder consists of two parts screw-threaded together. One part is the mouthpiece having a forward portion of reduced diameter with a few screw threads on the outer surface. The other part is a tubular member adapted to receive an end of a cigarette and provided with a few interior screw threads to engage the threads on the mouth-piece part. As modified according .to the invention, the mouth-piece part 10 has a portion 12 of reduced diameter forming a shoulder 14 spaced from the screw threads 16. The tubular member -18 with the interior threads 20 is not changed. The member 18 and mouth-piece part 10 have the usual duct 22 through which smoke is drawn from the cigarette into 3,265,074 Patented August 9, 1966 the mouth. A radial hole 24 extends outward from the duct 22 through the wall of the reduced portion 12 of the mouth-piece part. A thin sleeve 26 is fitted on the reduced portion 12 and is rotatable thereon. The sleeve is preferably provided with a knurled flange 28 to fa cilitate rotative adjustment. A series of holes of graduated sizes are provided in the wall of the sleeve. Four such holes 30, 3-2, 34, 36 are shown but the number of holes may be more or less as desired. In one embodiment of the invention, the four holes are made by drills of the following sizes:

piece part is larger than any of the holes through the sleeve. Rotative adjustment of the sleeve brings any of the holes in the sleeve into registration with the hole 24 so that .a vent of definite size is had. As indicated in FIGURE 3, When the holder is assembled, the tubular member 18 only presses against one end of the sleeve 26 and presses the other end of the sleeve into binding contact with the shoulder 14, thus trictiona'lly locking the sleeve against rotation regardless of any small variations there may be in the length of sleeves 26 when manufacture-d in quantity. The sleeve can be easily released for rotative adjustment by slightly unscrewing the tubular member '18.

The form of the invention shown in FIGURE 6 is like that shown in FIGURE 3 except that the mouthpiece part is in two parts '10 and 12, screwsthreaded together, instead of in one part 10 as shown in FIG- URE 3. A sleeve 26 with a knurled flange 28' is nearly identical with the sleeve 26 and is locked against rotative movement by being pressed between shoulders on the parts 18 and 1 2'.

I claim:

A vented cigarette holder comprising a mouth-piece having a tubular end portion of reduced diameter forming a shoulder, said reduced end portion having a screwthreaded part spaced from said shoulder and a radial hole through the wall thereof between the threaded part and the shoulder, a sleeve rotatably fittedon said reduced portion between said shoulder and said threaded part, said sleeve having a knurled flange and a series of holes of various sizes selectively registrable with thehole through said wall be rotation of the sleeve, and a tubular cigarette-receiving part in threaded engagement on said threaded part, the end of said cigarette-receiving part bearing only against an end of said sleeve to press the other end of the sleeve into binding engagement with said shoulder to lock the sleeve against rotation.
