Tarr‘ant, New York, N. Y. Application March 2'7, 1934, Serial No. 717,580 13 Claims. This invention relates to improvements in smoking devices, such as pipes and cigar and cigarette holders, and more particularly to means for treating and directing the flow of smoke dur ,,ing its passage from the point of origin to the mouth of the smoker. It is an object of this invention to cool and clean the smoke by providing a device having a combined cleaning and baffling element, thereby 10 ;increasing the length of the path of flow of smoke from tobacco to mouth. Another object is to provide a device of the character described having a combined position ing and closure means to adjust the position of 15 the cleaning and baffling element and to close one end thereof. Another object is to provide a device of the character described in which the said cleaning and baf?ing element is readily replaceable. Other and further objects of this invention 20 will be apparent from the drawing and the fol lowing description and claims. In the drawing, Figure 1 is a longitudinal view of one modi?cation of my device embodied in a cigarette holder and shows a cigarette in posi tion in the end of the holder. Figure 2 is a longitudinal sectional view of the cigarette holder shown in Figure 1. Figure 3 is a longitudinal view of the inner tubular element 8 of Figure 2. Figure 4 is a longitudinal view of a combined cleaning and baffling element, the intermediate tubular element ll of Figure 2. Figures 5, 5a, 5b and 5c are end views of dif 35 ferent modi?cations of the intermediate tubular element ll. Figure 6 is a longitudinal view of a combined positioning and closure device, the element 5 of Figure 2. Figure 7 is a longitudinal view of the outer tubular element 2 of Figure 2. Figure 8 is an enlarged longitudinal view partly in section and partly in elevation showing the assembly of the elements of Figures 3, 4i, 6 and 7 and indicates the path taken by smoke in ?owing therethrough. Figure 9 is a transverse sectional view taken along the lines II--II of Figure 8. Figure 10 is a longitudinal view partly in sec tion of a modi?cation of the invention for em bodiment in a pipe stem and indicates separately the bowl end of a pipe stem and a modi?cation of the element 8 of Figure 3 suitable for position ing therein. The assembly of the remaining ele ‘ments to complete the pipe stem is also, indicated. (Cl. 131-12) Similar numerals refer to similar parts throughout the several views. Referring to the drawing in greater detail, a device constructed according to the present in vention may comprise a bit or mouthpiece I hav ing a smoke passage ll therethrough. An outer tubular member 2 is mounted, preferably sep arately, as by a threaded joint, on one end of the mouthpiece. The opposite end of the tubular member 2 is mounted, also preferably‘ by an easily 10 separable connection, on a tobacco holding mem ber, such as cigar or cigarette holder 3 or pipe bowl 3’. An inner tubular member 8 is mounted in the rear end of the member 3, the smoke pas sage 9 through the member 8 forming a con 15 tinuation of the smoke passage ‘I through the member 3. Spacing means Iii, which may suit ably be in the form of notched radial ?ns, are mounted on the member 8, preferably at or near the end connecting with member 3. An inter mediate tubular member ii is positioned around the member 8 and is spaced therefrom and pref erably also from the end of the member 3 by the spacing means It. The inner surface of this member ii makes an easily separable connec 25 tion, preferably a loose frictional contact, with the spacing means it so that on disassembling the device this member is removed with the inner tubular member 3 and may then be easily detached therefrom, preferably by giving mem ber 3 a slight jar or shake to avoid having to touch the member M. This member ll becomes soiled in, use, and may be readily removed and replaced with a fresh member whenever desired. This member is preferably a cylinder having a , diameter greater than half the inside diameter of the outer tubular member 2, in order to permit its ready alignment and closure by the means illustrated. These comprise a tubular member 5 having a closed outwardly projecting conical end of a maximum diameter greater than the inside diameter of the member ii and preferably less than that of the outer member 2. The end of the member l I is closed by being pushed against this conical surface when the device is assembled. The member 5 is preferably mounted in the end of the mouthpiece l in such manner that it is a continuation of the smoke passage 4. Suitable means for‘ the passage of smoke from the space between the member l l and the outer member 2 into the smoke passage ll of the mouthpiece i may comprise preferably one or more holes 6 in the member 5 between the points of contact with the member H and the mouthpiece I, although the 55 2 2,126,422 smoke passage 4 may connect directly with this space, if desired. While the device has been illustrated with the inner tubular member 8 connected with the to bacco holding member 3 and the member 5 con nected with the mouthpiece I, it is recognized that these positions may be reversed, member 8 being mounted in mouthpiece l and member 5 in member 3, without departing from my inven 10 tion. The flow of smoke will then be reversed in its passage through the device, as will be un derstood. The manner of assembly illustrated is preferred, however, as it will be found to be cleaned more readily. The manner of adapting the device for use 15 with a pipe, as illustrated in Figure 10, in which the spacing means I0 is continued as a screw IU’ of su?icient length to engage both the outer member 2 and the stem of the pipe bowl 3', may 20 also be varied, and any other suitable connec tion may be used as desired. For example, the projecting end of the member 8' may be in the form of a slightly tapered cylinder, making a tight frictional connection with a similarly 25 shaped recess in the stem of the pipe bowl 3'. The intermediate tubular member H may also be closed at one end, as illustrated by | I’ in Fig ure 10. In this case the alignment and closure member 5 may be omitted, or it may be used 30 simply as a spacing means 5a for positioning the closed end of the member ll. Figure 10 shows a section through one of three spacing means 5a which may be made as a part of the mouth piece. The smoke passage ll will connect directly 35 or through suitable openings in the spacing member 5a, with the space between member II and outer member 2. The member ll serves to clean and cool the smoke by increasing its path of ?ow through the 40 device and by the reversals of flow caused there by which tend to throw out dust, droplets of moisture and other non-gaseous matter sus pended in the ?owing gas. This purifying ac tion may be increased by constructing the mem 45 ber ll of a suitable absorptive material, which’ may even be somewhat pervious to gas. For ex ample, it may be made so that at least one sur face, inner or outer or preferably both, is made of absorptive paper, decolorizing carbon, or other 50 materials having similar functions. The ?owing gas may also be ?ltered by placing a suitable ?l tering medium, such as loose cotton, in the an nular spaces inside or outside this member, or both. It has been found, however, that such ?l ters, even when loosely matted, are di?icult and inconvenient to insert and cause objectionably high pressure drop in use. A preferred ?lter may be prepared by attaching the ends of relatively short ?bres to the surface of the member II. 60 The ?bres then extend into the ?owing stream and 50 respectively. The ?bres may consist of cotton, wool, silk, hemp, wood pulp, rayon and other natural and synthetic ?brous materials. They may be attached to the surface of the mem ber II by any glue or cement suitable for the intended use or by other means, or they may be made a part of the surface by being mounted therein during its formation. A suitable method particularly for obtaining ?bres attached to the inside surface is to apply the ?bres to a sheet 10 of material, suitably paper, which is then rolled and formed into cylinders of desired diameter and length. The ?bres may be caused to stand out from the surface to which they have been attached, in the desired manner, by imparting 15 an electrical, preferably an electrostatic, charge to them while the adhesive is drying or setting. They may also be used in the form of a fabric, such as a chenille or a transparent velvet, which has numerous ?bres with loose ends projecting 20 from the surface of the fabric. Such fabrics may be strengthened and the back of the fabric made more rigid by application to one or both sides of a sheet of paper, Cellophane, or other suitable material. Or sugar water or a solution of a suit able hard resin in a volatile solvent may be ap 25 plied the back of the fabric and allowed to set preferably after the cylindrical form has been prepared. While the invention has been illustrated and described herein in its preferred forms, it is to be understood that it may be used in other forms, embodiments and modi?cations without depart ing from the spirit thereof.
