SMOKING PIPE Filed Feb. '7, 1964 United States Patent 3,236,959 SMKNG PEPE Henry Paul, Jr., 2l2 Jane St., Weehawken, NJ. Fii'etlV Feb. 7, i964, Ser. No. 343,305 2 Claims. (Cl. ISI- 176) The present invention relates to smoking tobacco pipes, and more particularly tothe type in which the tobacco is adapted to be burned from the bottom up, rather than from the top down. v

A primary object of the invention is to provide an improved smoking pipe of the aforementioned type which comprises improved means for the prevention of distillation of nicotine or other harmful tars while simultaneously precluding the conveyance of saliva to the tobacco or the return thereof to the mouth, thus preventing any tobacco tongue bite.

Another object is to provide an improved pipe according to the preceding objective in which there is provided under draft means in combination With conduit means forming an overhead and down-drafty means adjacent to and in communication with the bowl and in operative communicationA with the conventional stem bore, which pre` vents the formation of any soggy heel or hard core of tobacco, thus effectively facilitating the complete combustion of saidY tobacco, providing more enjoyable smoking with relatively little or minimal cleaning thereof required.

Still another object is to provide novel yieldable and pivotable base cover means in combination with the bowl of the pipe to facilitate easier and more efficient loading, lighting and burning, and cleaning thereof with the attendant advantages of' safety and tire preventiveness by precluding the' emission'of any sparks whether the pipe is inadvertently spilled, placed upon furniture, or put into the users pocket' while containing a burning charge of tobacco, in addition to providing a very satisfying and palatable smoke even when subjected to severe rainy orwindy Weather conditions.

These and other objects, such as the provision of a compact, durable, yet readily manipulatable pipe bowl and `cover structure which -is attractive in appearance and relatively inexpensive tomanufacture, will become more apparent from the following detailed description taken in conjunction with the accompanying illustrative drawing figures, in which FIGURE l is a longitudinal cross-sectional view of my improved pipe;

FIGURE 2 is a bottom plan view of the pipe of FIG- URE l;

FIGURE 3 is a detailed exploded composite sectional and side elevational view of the structural elements of my improved pipe; and

FIGURE 4 is a partial side elevational View, with parts shown in section and illustrating a modification of the device.

Referring now to the drawings, wherein like reference characters designate corresponding parts throughout the several :figures of the drawing, A designates the pipe generally, having a downwardly opening bowl B, a base cover C and a stem S.

More specifically, the bowl B, made preferably of briar, comprises a generally barrel-shaped, combustion chamber with a vertically disposed axis and defined by cylindrical and generally vertically disposed side walls 12 and a top flattened wall 14, said chamber 10 or bowl having an open bottom rim or mouth 16 which is adapted to be closed by said base cover means C during use.

The stem S comprises a composite shank including a portion 18 formed preferably integral with and attached at about the mid-point of the bowl between its top 14 3,2%,959 Patented Jan. 25, 1966 rice and bottom cover C, and a detachable stem portion 2`0` terminating in a conventional open-ended mouth piece 22'. The stem Sis provided with the usual horizontal longitudinal conduit 24 communicating with the chamber it) by means of a transverse and vertically disposed connectingv conduit or flue channel 26. The channel 26, which serves as the down-draft flue, is arranged in spaced relation and generally parallel to the bowls combustion charnber 10 as shown in FIGURE l, and includes an enlarged area or counterbore 28 which isdrilled or otherwise suitably formed therein from the bottom rim lo. Said counterbore 28 preferably extends above the intersection of stem conduit 24 to provide a combined miniature expansion and cooling chamber for the smoke during its travel through the conduits 26 and 24.

The counterbore area 28 immediately above the intersection of conduit 24 is used to provide a moisture collecting trap 3l), and isfurther used to house the covers pivotal and axially yieldable anchor means 32, to be described in detail hereinafter.

The cover C is provided with a metallic or ceramic shield'34 or tire resistant liner secured thereto as by means of a recessed rivet 36 or the like, to provide several shielding functions. The cover is adapted to be first yieldably extended away from the rim 16 to lclear said shield and then pivotally rotated about the anchor means 32 to provide access for filling with tobacco, igniting and subsequently cleaning said bowl. The anchor means, 32, as shown', comprises a fastener such as a screw 38, an expansion spring 49, a bearing sleeve 42 having shouldered seat 43, and a fastener-securing insert or screw anchor 44 having complemental internal threads to accommodate the threaded shank of said screw 38' whose head is provided with an enlarged slot, all of which are more clearly shown in exploded fashion in FIGURE 3.

Thescrew anchor or tapped insert 44 is either externally threaded to mate with threads 46 provided in counterbore 28, or it may have a knurled outer surface and be press-tit Within the bore, to a distance spaced below the intersection of stem conduit 24` and counterbore 23, to provide the aforementioned moisture trap 3i) thereabove. Cover C is provided with a bore- 48 in axial alignment with the counterbore 28 in the rim, in which the shouldered bushing or bearing sleeve 42 is adapted to be recessed, and the latter, in turn, being adapted to receive both the spring 4%, against its shouldered seat 43, and screw 38 as shown in FIGURE 1 when assembled.

The outer or front Wall l2V of the bowl may be provided with a plurality of spaced air inlet apertures 59 adjacent the lower rim area i6, as for example five or six have been found to provide .a very satisfying, cooler smoke than conventional pipes. Said apertures Si) may be selectively covered or uncovered to suit the individuals desires, as by covering or uncovering the same with ones finger.

The illustration of FIGURE 4 shows a modification of the cover, anchor means, and cleaning access structures of the precedingly described exemplication. As shown therein, the modified cover eliminates the need of bore 48 and substitutes therefor a hinge 52. The hinge is secured to the respective parts by wood screws or other suitable fastening means. The modiiied anchor means eliminates the need of spring 4t). The sleeve 42 is placed in the lower portion of the bore 28 and serves to position and retain the headed end of the screw 3S, the underside of the cover C being recessed as shown, to accommodate the head of the screw. The cover includes a recessed portion 54 and the bowl includes a matching protruding portion 56 having a detent on an inner surface thereof. |The cover includes a spring loaded catch 58 for retaining the cover in its closed position.

3 Small force is required on the cover to disengage the catch from the detent and lower the cover on hinge 52. The phantom line drawing of cover C illustrated this lowered position and shows more clearly the relative position afforded the elements by such movement.

The function of shield 34 is two fold: First, it pre.

vents burning particles of tobacco from dropping and possibly escaping from apertures 50; second, it collects products of combustion by virtue of its shape which otherwise would collect on the cover and interfere with its tight closing; and third, it protects the cover from Charing when the pipe is first lit.

The operation will now be summarized as follows: The pipe is inverted to place the combustion chamber or bowl with the open side upward. In the exemplication of FIGURE 1, the base cover C is yieldably pulled in an axial direction away from the rim 16 of the bowl against the pull of spring 40, a sufficient distance to clear the concave shield 34, then rotated to the side about the pivotal axis of the mounting screw and bushing 38 and 42 respectively, to expose the bowl for charging. After the charge of tobacco has been inserted, it is initially ignited in this same inverted position and subsequently the base cover C is again axially pulled out and returned to its place with respect to the vertical axis of the bowl, and then the pipe is returned to its normal upright position, whereupon the ignited charge of tobacco is supported by the bowl and the .air inlets or apertures S assure continued combustion of the tobacco as it burns from the bottom upwardly, with the smoke being down drafted through the conduit 26 prior to passage through the stern; conduit 24, thus together with trap 30, reducing the passage to the mouth of juices which may be distilled during combustion.

The operation of the m'odilicat'ion of FIGURE 4 diiers from the above only in the manner in which the cover is opened and closed. A small lifting force on the cover disengages spring catch S from the detent in portion 56 and allows the cover to pivot to the phantom line position. Filling and lighting is then accomplished before the cover is returned to the closed position and the catch engages the detent.

Cleaning of this improved pipe is facilitated by simply removing the base cover as a unit, by turning said screw with a coin or small tool, thus permitting passage of a pipe cleaner in through conduits 2S and 26 to the bowl chamber 10.

From the foregoing, it is apparent that an improved pipe has been evolved which fulfills the objects and advantages as set forth in the preamble of this specication.

While specic details have been shown and described other changes and modications may be made, such as providing suitable combustion air apertures in the base cover rather than in the rim, or the provision of a cover having a concave and tire-resistant lining shield formed integrally therewith, without departing from the spirit and sco-pe of the invention as :defined in the appended claims.

What is claimed is:

1. A tobacco smoking pipe adapted for botto-m up burning of tobacco, comprising in combination a bowl lhaving a vertical axis and including a combustion chamber ha'ving a closed top and an open base end, a stern connected to said bowl portion and having a smoke conduit in operative communication with said combustion chamber, a baseend-mounted cover having an inner and outer face for enclosing the combustion chamber, an anchoring means disposed in conjunction with said cover and bowl, said cover anchoring means comprising a fastener securing means provided in said bowl portion adjacent the combustion chamber, a bearing sleeve carried by said cover and having a shouldered seat portion and disposed within aligned apertures formed in said cover and bowl portions, a removable fastener element having an enlarged head end extending through said bearing sleeve disposed in said cover with the head end disposed adjacent the outer face of said cover, with its other end adapted for cooperation with said fastener securing means aforesaid, and yieldable means interposed between the headed end of said fastener element and the shouldered seat portion of said bearing sleeve.

2. A tobacco smoking pipe as dened yin claim 1 wherein the yiel'dable means interposed between the headed end of the yfastener and the bearing seat is a spring.
