Application October 20, 1952, Serial No. 315,655

3 Claims. (Cl. 131-498) This invention relates to new and useful improvements and structural refinements in Smoking pipes and has for its principal object the provision of a device of the character herein described which will afford a smoker a uniform dry, non-biting and cool smoke.

Another object of this invention is to provide a pipe having a bowl which will remain cool to the hand while providing conditions for eflicient combustion to cause the tobacco to burn to a cool dry ash leaving no wet residue.

One of the features of the invention is the means used for assembling the various elements for rapid disassembly. Further, the pipe makes use of a briar tobacco receiving cup in which the tobacco may be burned which includes a filter and a cap ring which may be readily disassembled from the briar bowl for washing.

Still other objects of the invention reside in the provision of a smoking pipe that is simple in construction, made from a minimum of parts, making use of interchangeable and renewable filter elements, durable, designed so that it will balance in an upright position, and which is relatively inexpensive to manufacture.

A preferred embodiment of the invention has been illustrated in the accompanying drawings, by way of ex ample only, wherein:

Figure 1 is a side elevational view of the smoking pipe comprising the present invention, with parts thereof being broken away to show other parts in section in greater detail;

Figure 2 is a horizontal sectional view as taken along the plane of line 2-2 in Fig. 1 and showing the construction of the upper portions of the pipe and in particular the air channel formed between the flanged ring and the bowl of the pipe;

Figure 3 is a horizontal sectional view as taken along the plane of line 33 in Figure 1, and showing in detail the construction of the filter element of the pipe with a portion of the filter element being shown in plan view;

Figure 4 is an exploded perspective view showing the construction of the filter element and other associated parts;

Figure 5 is a horizontal sectional view as taken along the plane of line 5-5 in Figure 1 and showing the construction of the annularly spaced passageways used in cooling the bowl;

Figure 6 is a bottom plan view of the pipe; and,

Figure 7 is an exploded sectional detail view of the upper portion of the bowl and associated parts.

With continuing reference to the accompanying drawings wherein the same reference numeral designates similar parts throughout the various views, it will be noted that the pipe is formed conventionally of two main portions, a hollow stem 10 and a bowl 12. The stem 10 is provided with a smoke duct 14. The bowl 12 is provided with a tobacco receiving and burning cup 16 and is preferably formed from an imported briar or other fine woods used in tobacco pipes.

be seen that the bowl 12 is stepped so as to be provided with an inner annular recess 18 in the upper end. The recess is of such size as to form a seat 20 on which a ring 22 having a flange 24 is adapted to be placed, the recess being enlarged at its upper end. The bottom of the flanged ring 22 will rest on the seat 20 and the flange 24 together with the ring 22 will provide an effective seal. Thus, an annular air passageway or channel 26 is formed.

The bowl is provided with a filter receiving cavity that is threaded at its lower end as at 28. A filter holder having a threaded portion 30 and a portion of reduced diameter 32 is threadedly secured within the filter receiving cavity. A hollow portion 34 is formed in said filter holder for reception of filter material 36 which may be formed from coiled pipe cleaners in the shape of two disks,

. the disks being shown in contact with each other in Fig. 1

Referring more particularly to Figures 1 and 2, it will but separated from each other in Fig. 4 or any other suitable material. A transverse hole 38 is formed in the portion 32 of reduced cross-sectional area and opens into the hollow portion 34 and into the filtered smoke passageway 40 formed between the walls of the bowl defining the cavity and the outer wall of portion 32 of reduced diameter. The duct 14 opens into the filtered smoke passageway 40. The bottom of the bowl is formed in a horizontal plane and the bottom of the filter holder is provided with recesses 42 for reception of lugs 44 on keying device 45 which is used for removing the filter holder by rotary motion.

A plurality of annularly spaced air passageways 48 are formed in the bowl 12, one of which indicated at 48a opens into the smoke duct 14. Each of the

passageways

48 and 48a opens into the air channel 26. There is provided an air duct or opening 50 which extends through the side wall of the bowl 12 and which opens into the air channel 26.

A brass bushing 52 is provided and an aperture is provided as at 54 for connecting the tobacco receiving cup with the filter cavity. Hence, upon applying suction on the mouthpiece 54 of the stem 10, the smoke from the burning tobacco in the cup 16 will be drawn through the filter and into the hollow portion 34, then through hole 38 into the annular passageway 40 and finally into duct 14. Air from the outside can enter the duct 50 to cool the bowl and can pass through the passageway 48a to mix with the smoke passing through the duct 14. Further, upon suction through the mouthpiece 54 with the hand over the opening 50 to thus seal it, an increased suction and draft on the burning tobacco will be provided. Thus, a greater amount of smoke will be drawn in.

Since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the precise embodiment shown and described, but also suitable modifications and equivalents may be readily resorted to which fall within the scope of the appended claims.

What is claimed as new is as follows:

1. A smoking pipe comprising a bowl having a tobacco receiving cup and a stem, a hollow internally threaded filter cavity in said bowl, a filter holder threadedly secured to saidbowl in said filter cavity, an apertured bushing threadedly secured in said bowl in communication with said filter cavity and said tobacco receiving cup, an inner annular recess in said bowl opening into and forming an enlargement of said tobacco receiving cup, a ring secured in said recess, a plurality of spaced passageways in said bowl in communication with said recess, a smoke duct in said stem, said duct opening into said filter cavity and one of said passageways, and an air duct extending transversely through said bowl in communication with said recess.

2. A smoking pipe comprising a bowl having a tobacco receiving cup and a stern, a hollow internally threaded filter cavity in said bowl, a filter holder threadedly secured to said bowl in said filter cavity, an apertured bushing threadedly secured in said bowl in communication with said filter cavity and said tobacco receiving cup, an annular recess in said bowl opening into and forming an enlargement of said tobacco receiving cup, a flanged ring secured to said bowl sealing a portion of said recess from said tobacco receiving cup to form an annular air channel between said bowl and said ring, said bowl having an air duct providing communication between said air channel and the atmosphere, a plurality of spaced passageways in said bowl in communication with said air channel, a smoke duct in said stem, said smoke duct opening into said filter cavity and one of said passageways.

3.
