TOBACOC PIPE.
Application illed April 16, 1984. Serial lo. 708,980.
This invention relatesto new and useful improvements in tobacco pipes and the ob- 'ects of the invention are to provide a pipe aving its parts, which usually come in con- 5 tact with and absorb the nicotine moisture,
rovided with suitable non-absorbent lining in order to prevent the absorption of this moisture by the pipe,'particularly the bowl and stem thereof, thus preventmg said pipe l from being detiled by said moisture and becoming strong and rancid.
Further objects of the invention are to provide a pipe having a suitable trap or well interposed between the bowl an bit l for collecting the nicotine moisture and to construct said trap so that its contents cannot escape therefrom into the bowl Vor the bit, irrespective of the position which said pipe may occupy, and to form said bit detachable in order to facilitate cleaning of the pipe. c
Still further objects `of the invention are to provide a suitable expansion or cooling chamber in the smoke passages of the pipe whereby the smoke traversing said passages expands and is cooled to the proper degree thus insuring a cool and pleasant smoke.
Other objects of the invention are to provide a detachable bit for a pipe whereby said bit when detached can be used as a cigarette or cigar holder.
With these and other objects in view, my invention consists in certainv novel features of construction and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal cross section through my improved pipe.
Figure 3 is similar to Figure 1 with the bit detached `from the stem of the bowl.
Figure 4 is a longitudinal cross section through a modiiied form in which the bit is adapted to be used as a cigar holder.
Figure 5 is an enlarged longitudinal cross section showing the disposition of the cooling chamber illustrating in dotted lines how the moisture is trapped when the pipe occupies a tilted position.
Figure 6 is a longitudinal cross section through another modified form wherein the bit is connected to a stem designed tobe used as a cigar holder and the smoke passage in the'bit is provided with a helically shaped cooling member.
Figure 7 is a transverse cross section taken on line 7-7 of Figure 6.
Figure 8 is a transverse cross section taken on lines 8--8 of Figure 6.
Figure 9 is a longitudinal cross section of another modified form in which the coolin chamber is formed in the stem of the bow Figure 10 is still another modified form.. in which the bit is provided with metal tubing which when the bit is attached to the bowl stem extends therethrough and terminates in the bottom of the bowl.
Figure 11 is an enlarged horizontal cross section partly in planelevation of the metal tubing and the neck extension.
Figure 12 is a still further modified form illustrating my invention as applied to a pipe having a detachable bowl.
`Figure 13 is a view looking against the underside of the bowl when detached.
Figure 14 is a plan view of the bowl receiving socket.
The present invention is particularly designed for pipes having a straight stem and the pur se of the invention is to provide the smo e passages of the bowfand its stem, which parts are usually made of absorbent material such as briar, with suitable nonabsorbent lining preferably made of aluminum in order to prevent the nicotine moisture from being absorbed through the walls of the smoke assages and to provide a suitable cooling c amber or trap in the bit or the bowl stem in which the smoke is cooled before passing through the bit and in which the nicotine moisture is permitted to collect thus preventing it from passing through d the bit into the mouth of the smoker or re 3. nd 14 is orm an upwardly presented elongated inlet opening 14a. This construction provides a metal non-absorbent bottom lining for the lowermost portion of the bowl and any moisture formed therein 1s conveyed away from the bowl by said tube 15. Bowl stem 11 terminates in a tapered reduced portion 17 having an annular shoulder 18. The extreme end of this portion has fitted over it a cap 19 preferably of aluminum and this cap is soldered or otherwise secured to tube 15 in order to form afluidtight joint and prevent moisture from linding its way through sald joint to the bowl stem. A bit or mouthpiece 20 is provided with a stepped longitudinally disposed bore 21 which terminates at one end in a tapered bore 22, the latter being adapted to receive and form a tight fit wlth the tapered portion 17 of bowl stem 11. A band of metal is preferably arranged on this end of the bit and reinforces said end.
When the bit is placed on the bowl stem, end 16 of tube 15 is seated in and forms a fluid tight joint with section 24 of bore 21 i and said end of the tube is in direct communication with the reduced bore 25 formed in the mouth end of the bit. Bores of sections 26 and 27 are comparatively of greater diameter than the external diameter of the tube 15 and consequently annular chambers 28 and 29, respectively, are thus formed which allow the smoke traversing the forward half of the tube to enter said chambers through a series of openings 30 and 30EL formed in said tube, thus allowing smoke to be cooled in said chambers, whereupon the smoke is withdrawn from the chamber through said openings and passes to the mouth of the smoker through the remaining portion of the tube and the bit. Chambers 28 and 29 not only form expansion or cooling chambers for the smoke but they are also utilized as traps or wells for receiving and collecting the nicotine moisture which is allowed to escape from tube 15 through the downwardly presented openings 30". These openings 30 and 30n are so disposed on tube 15 relative -to the cooling chambers that proper circulation of smoke therethrough is obtained thereby eliminating the accumulation of stale smoke in said chamber. Furthermore, said openings are spaced suitable distances from the respective ends of tube l5 whereby if the pipe is tilted in any direction, said openings will be disposed a suitable distance above the level of the moisture contained in said chambers and said moisture will be prevented from yreentering said tube through said openings.
The bit shown in Figures 1 and 3 is designed to be used as a cigarette holder when detached from the bowl, bore 22 being of sufficient dimensions to receive one end of a cigarette. The bit shown in Figure 4 has its receiving end 31 formed of slightly larger dimensions in order to provide a comparatively large and suitably shaped mouth 32 which when the bit is detached from the bowl is designed to receive one end of a clgar whereby said bit can be used as a cigar holder. A band 34 of metal is placed over this end of the bit in order to reinforce the same, and, by contacting with the cigar, radiate the heat produced thereby.
The metal tubing 15 is cemented in the entire smoke passage or bore 12 and extends through the enlarged bores or chambers 26 and 27 and is frictionally seated in the smaller bore 24, thus preventing moisture from passing from the trap through the bit to the smoker. The metal tubing 15 and metal cap 19 protect' the wood or other absorbent material from which the bowl is usually made from the nicotine moisture so that the latter cannot be absorbed by said material and the pipe remains in proper condition for pleasant smoking.I 4 f The mouth of the bit fits over the end of the stem and the tubing 15 has a tight fit in bore 24 thus providing two connections and points of support between the bowl and the bit. When said parts are detached they can be easily cleaned. If desired, the bit can be detached and used as a cigar or cigarette holder, the open end of the bit being of proper dimensions to accommodate one end of the cigar or cigarette.
In Figures 6 to 8 is shown a further modi-l fied form of a pipe wherein a detachable tapered stem 35 is interposed between the bowl 36 and a bit 37. One end of the stem fits over and has frictional engagement with the shank or stem portion 36n of bowl 36 and is of proper shape and size so as to be used when detached from the bowl as a cigar holder. The other end of said stem is of smaller diameter and frictionally engages thereduced shouldered end 37 of bit 37 The stem 35 is used as a cooling or expansion chamber for the smoke and acts also as a trap for receiving and collecting the moisture and is therefore lined with a metal tubing 38, preferably of aluminum, and a cap 39 is fitted over the extreme end of bowl shank 36a so that the nicotine moisture'which collects in said stern does not come in contact with the absorbent material of the stem or pipe. Bit 37, being made of hard rubber, bakelite, or other similar material, is nonabsorbent in itself and no metal linin is therefore necessary. `A tube 40, preferagbly of aluminum. extends through the bowl shank 36El and has one end terminating in the bowl 36 and has its other end projecting a Suitable distance past cap 39 into the cooling chamber of stem 35. This stem is preferably cemented in position in the bowl shank and where it passes through the cap 39 the joint is soldered or otherwise sealed in order to form a perfect joint and prevent leakage of the moisture to the absorbent material of the pipe.
The bit 37 is provided with a tube 41 which is cemented or otherwise secured therein and has one end projecting a suitable distance into the cooling chamber in stem 35. A helical or cork-screw member 42 of metal is removably arranged in tube 41 and serves to increase the cooling area with which the smoke in traversing the bit comes in contact. The extreme outer or projecting end 0f this member carries a plate or head 42 which is spaced a proper distance from the projecting end of said tube and acts as a baille or dellector in order to insure proper circulation of smoke through said cooling chamber.
The form illustrated in Figure 9 comprises a bowl 44 having its stem or shank 44* recessed at one end to form a cooling chamber or trap 45. This cap has a non-absorbent lining 46 and projecting into said chamber is one end of a metal tube 47, the opposite end 'of which terminates in and communicates with bowl 44. A bit 48 has a reduced portion .48 `which rictionally engages the open end of stem 44 and closes said chainber 45. A short tube 49 of aluminum is secured in the bit 48 and has its one end projecting into chamber a suitable distance beyond the end of the bit. The projecting ends of tubes 47 and 49 allow the pipe to be tilted in any direction without danger of the moisture contained in trap 45 ,entering the bowl or the bit since the ends of said pi are'of suiicient length and project above t e level of the moisture contained in said trap.
In the form shown in Figures 10 and 11, the shank of a bowl 50 has a recessed end to form a cooling chamber or trap 51, and the latter is lined with a metal tubing 52, as in the previous form, but this tubing has Y formed integral therewith a neckv extension 52* of smaller diameter which extension rojects through the shank into the bowl. his neck extension is adapted to receive one end of a tube 54 which is secured at its op osite endin a bit 55. That portion of tu 54 which traverses chamber 51. has suitable openings or vents formed therein foiY permitting smoke to escape into said chamber and to be drawn from said chamber into the bit. The extreme end of tube 54 which is disposed in the bowl is undercut to form an overhanging portion orti 54* and is provided with a series of r orations or apertures to permi the sino e to be drawn therethrough into t e tube as well as through the open undercut end thereof. This construction prevents the tobacco from entering and clogging the smoke 'passage in said tube and also prevents the moisture from coming in contact and being absorbed by the material from which the bowl is made.
In the form disclosed in Figures 12 to 14 a bowl 56 is provided at its lower end with va threaded extension 56l which is ada ted to be screw-seated in a socket mem er 57 formed in one end of a stem 58. The opposite end of said stem frictionally engages one end of a bit 59. A trap or cooling chamber 60 is formed in socket portion 57 and extending thereinto is the lowerpend of a tubular member 61, the upper end of which opens into the bowl 56.' Member 61 is preferably held in position by a circular plate 62 to which it is soldered or otherwise secured and said plate is fixed to and forms -a non-absorbent linin for the underside of the threaded portion of the bowl. A tube 64 of aluminum is secured at one end in bit 59 and extends through a bore 65 in stem 58 and terminates adjacent to chamber 60. This tube is provided an appropriate distance from its free end with an aperture 66 whichestablishes communication between said tube and bore or chamber 65, which latter is of larger diameter than said tub'e and forms a cooling chamber for the smoke and a trap for the moisture. f
A pipe or cigar holder constructed according to my invention successfully excludes the moisture from the bit and provides a cooling chamber or chambers for cooling the smoke before it is drawn into the bit.
' Obviously, various minor changes in the construction of my improved pipe and holder may be made and substituted for those herein shown and described, without departing from the spirit of 'my invention.
