Description
May 16, 1939. P. 5 PAGE 2,158,301 7 TOBACCO PIPE Filed Nov. 8, 1957 ATTY Patented May 16, 1939 UNITED STATES PATENT o Flcs 2 Claims.
The invention relates to improvements in tobacco pipes as described in the present specificae tion and shown in the accompanying drawing that forms part of the same.
The paramount object of the invention is to provide an improved pipe structure by which moisture and nicotine juice are effectively absorbed in the passage of the smoke through the stem; and to obtain thereby a cool dry smoke unaccompanied by deleterious substances that detract from the full enjoyment of smoking.
A further and salient object is to produce a smoke passage structure incorporating an absorbent sleeve associated with inner and outer circulation chambers so constructed and arranged with a view to drying outthe sleeve as it accumulates moisture, tobacco juice and saliva.
A still further object is to produce a structure as above defined in which the abs'orbe'nt sleeve does not need replacing from time to time, as is required in constructions hitherto proposed, and generally to provide a more efficient and serviceable tobacco pipe of the absorbent sleeve type.
Having briefly recounted the nature and objects of the invention, subsidiary objects and advantages will be apparent from the ensuing comprehensive disclosure of the invention, in; its practical embodiment illustrated in the accompanying drawing.
In the drawing, Figure 1 is a side elevation of the tobacco pipe.
Figure 2 is a longitudinal section thereof.
Figure 3 is a view partly in section of the absorbent sleeve mounted upon a tube through 85 which the smoke is drawn.
Figure 4 is a detail of the tube.
Figure 5 is an enlarged cross section taken on line 5-5 of Figure 2.
Like numerals of reference indicate correo sponding parts in each figure of the drawing.
The drawing is illustrative of a practical embodiment of the invention and depicts a conventional bowl 6 integral with a stem 1 terminating in the usual mouth piece 8. The smoke passage leading off the bowl is indicated at 9 and that of the mouth piece is denoted at H).
In performing the invention a chamber ll of substantial diameter and length is axially provided in the stem and preferably extends from a 50 point within the vicinity of the bowl to and within the mouth piece as shown. The chamber communicates with vent openings or perforations l2 in the stem, which are disposed at opposite sides of the stem midway thereof. By way of illus- 55 tration but not of limitation, the perforations are shown in the form of slots successively arranged; it is to be understood however that circular or other shaped openings maybe resorted to. The office of the perforations is to admit air into the chamber, and the purpose of locating them medial of the sides of the stem is to provide the stem with an imperforate bottom wall that will catch any deposits of tobacco juice as later dealt with.
The juncture l3 of the mouth piece may be of the well known type such as furnished by an annulus M by which an interfitting connection is afiorded. It will be understood that this may be modified according to circumstance of manufacture without departing from the spirit and scope of the invention. If so desired, the mouthpiece may be permanently cemented in place inasmuch as itis' not required to be removed for replacement of the sleeve.
Extending axially throughout the chamberis a metal tube l4 in alignment with the smoke passages 9 and I0, and seated in counterbores l5 therein. The forward end iii of the tube may and will be beveled to facilitate its entry in the respective counterbore.
The tube is constructed with a longitudinal series of staggered perforations ll of suitable size and shape to compose smoke passages and outlets whereby tobacco juice and saliva may gravitate radially of the bore of the tube; which bore constitutes a smoke passage supplementary to and in register with the smoke passages 9 and I0.
To aid in promoting flow of smoke through the perforations l1, it is proposed to diametrically reduce the bore of the tube at several points throughout its length in order to produce abrupt Shoulders or bafile faces as at I8 affronting the direction of travel of smoke to the mouth piece. The reduced portions of the bore preferably taper toward the mouth piece. By reference to Figure 3 it will be observed that three bafile faces are depicted, and it is to be understood that this number may be varied in practice.
Concentrically encircling the tube and co-extensive therewith is an absorbent sleeve ill of fibrous material, such as paper, having the property of capillary attraction. This tubular agent is constructed so as to be impervious to air for the purpose in hand. An important feature of this sleeve is that its internal diameter is much greater than the external diameter of the metal tube about which it is circumposed so as to produce an intervening circular space for circulation of smoke. The sleeve is mounted in spaced relation on the tube preferably by collars 20, of which there are several. The collars are spaced at intervals along the tube to divide the circular space into compartments 2| and to adequately support the sleeve at spaced points throughout its length in order to preclude its sagging. The sleeve may have its ends turned in against the tube, as shown; and the collars are integral with the tube and of a circular cross section.
From an inspection of the drawing, it will be seen that the sleeve substantially fills the chamber II, but leaves an ample surrounding space 22 for circulation of air.
In the use of the pipe, the smoke passes di- I rectly from the passage 9 into the bore of the metal tube M and enters the compartments 21 within the absorbent sleeve about which it circulates. The baffle faces I8 assist in so diverting smoke as to cause it to pass through the periorations I'l into said compartments and also tend to retard the passage of nicotine juice through the bore so that it will gravitate through the perforations and drop onto the sleeve. Accordingly, moisture and nicotine juice is absorbed by the sleeve which is dried by circulation of air thereabout admitted by the vent openings [2. By virtue of these openings being at the sides of the stem, any nicotine juice filtering through the sleeve will be deposited on the bottom of the inner face of the chamber H, where it will dry out. Since the sleeve is impervious, air will not be drawn in through the vent openings. The advantage and utility of drying out the sleeve by this construction has proved to be most prac tical and additionally the sleeve does not have to be renewed.
Such modifications may beresorted to as comewithin the spirit and scope of the appended claim.
absorbent sleeve solely carried by said tube and extending from one to another of the annular enlargements thereof, said sleeve being made a slip fit on the enlargements and defining a compartment between enlargements communicating with said holes which enable entrained nicotine juice to gravitate to the sleeve for absorption, there being a space between the periphery of the sleeve and the wall of the aforesaid chamber into which air circulates to dry out the sleeve.
2. A filtering device. for insertion in the stem of a tobacco pipe, said device comprising a nonabsorbent tube for axial placement in the bore of said stem so that the bore of the tube functions as a part of the smoke passage, said tube having a succession of spaced annuli about its periphery of a uniform diameter and radial holes in the wall portion between adjacent annuli communieating with its bore, and a thin-walled sleeve of absorbent .material mounted upon said annuli, being a snug fit thereon and prevented from sagging by the support afiorded by the annuli at spaced locations along its length, said sleeve in conjunction with adjacent annuli providing a compartment communicating with said holes, the holes operating to enable entrained nicotine juice to gravitate to the sleeve for absorption.
