DETAILED DESCRIPTION Referring to FIG. 1, one embodiment of the smoking device 10 is shown. The smoking'device 10 includes a mouthpiece 12 with an elongate cylindrical extension 14, a filter cartridge 16 including an; orifice metering plate 18, a smoke entry portion 20 and a ferrule 22' adapted for insertion within the smoke entry portion 20 g to circumferentially retain an inserted cigarette (not shown).
Referring also to FIG. 2, the smoking device 10 is shown as assembled. The filter cartridge 16 is inserted into the elongate cylindrical extension 14 and extends into the mouthpiece 12. The diameter of the elongate cylindrical extension 14 is slightly larger than the filter cartridge 16 for easy insertion therein.
The orifice metering plate 18 has a positioning means or longitudinally extending rib 24 integrally formed therewith. The elongate cylindrical extension 14 has a radial locking means or receiving slot 26 extending longitudinally from the front end 28 of the elongate cylindrical extension 14. Upon insertion of the filter cartridge 16 into the elongate cylindrical extension 14, the filter cartridge 16 is rotated until the positioning means 24 mates within the receiving slot 26, whereby the orifice metering plate 18 is held radially fixed relative to the elongate cylindrical extension 14 and mouthpiece 12 and capable of undergoing rotational movement therewith.
The smoke entry portion 20 is then press-fitted over the elongate cylindrical extension 14. The smoke entry portion 20 has a diameter slightly larger than that of the elongate cylindrical extension 14 and orifice metering plate 18 for readily mating thereover.
A receiving channel 30 is circumferentially arranged within the smoke entry portion 20 adjacent the rear 32 thereof. The receiving channel 30 is capable of mating with a peripheral ridge 34 circumferentially positioned adjacent the back end 36 of the elongate cylindrical extension 14. The longitudinal mating means 30 and 34 hold the mouthpiece l2 and smoke entry portion 20 longitudinally fixed while allowing relative rotation therebetween.
The ferrule 22 is arranged within the front end 38 of the smoke entry portion 20, being fixedly held therein.
Referring also to FIGS. 3 and 4, the assembled smoking device provides direct engagement between the orifice metering plate 18 and a vertical wall 40 arranged in the smoke entry portion 20. The vertical wall 40 includes a smoke inlet 42 and an enlarged blind hole or air inlet 44.
Referring particularly to FIG. 3, the orifice metering plate 18 has a plurality of pairs of orifices, A-A', B- B, and C-C', respectively, as disclosed in the Tucker US. Pat. No. 3,270,751. Each orifice has its center positioned equidistant from the central axis 45 of the orifice metering plate 18 and has an equal angular spacing relative to adjacent pairs. Further, each orifice has a specific flow area relative to the other orifice in its pair to provide a predetermined ratio of flow areas for each pair of orifices and thus a predetermined ratio of air to smoke when a selected pair of orifices is axially aligned with the smoke inlet 42 and air inlet 44 in the vertical wall 40. (Orifice A is actually a false hole permitting no transmission of air or smoke therethrough.)
The orifice metering plate 18 is maintained in direct contact with the vertical wall 40 by resilient urging means or resilient arms 46 located at the front end 28 of the elongate cylindrical extension 14, thereby urging the selected pair-of orifices, e.g. A A', into direct contact with the smoke and air inlets 42 and 44 respective- 1y, forming conduits for the uninterrupted transmission of smoke and air therethrough. The vertical wall 40 is so positioned within the portion '20 as to leave a circumferential gap as indicated by the arrow in FIG. 2.
Referring particularly to FIG. 4, the inside surface 48 of the smoking entry device has a plurality of grooves 50, generally equal to the number of orifices, longitudinally arranged therein. One of said grooves 50 communicates with the air inlet 44 to transmit air to the one orifice of the selected pair of orifices, while smoke is being transmitted through the other orifice. As indicated in FIG. 2, air entering through the circumferential gap is adapted to pass between the outer periphery of the ridge 34 and the bottom of the channel 30. As seen in FIG. 4, an annular space is located between the members 14 and 20 so that ambient air can pass therethrough to the inlet 44 when a smoker draws on the mouthpiece 12.
Groove engaging means or deflectable tabs 52 are arranged on the elongate cylindrical extension 14. The deflectable tabs 52 mate within grooves 50, cooperating with theradial locking means 26, to angularly align the selected pair of orifices with the smoke and air inlets 42 and 44, respectively. The orifice metering plate 18 and the smoke entry portion 20 are held in a predetermined radial positionuntil the smoker desires to change the smoke to air ratio by rotating the mouthpiece 12 relative to the smoke entry portion 20 to align the smoke and air inlets 42 and 44, respectively, with another pair of orifices.
The smoke entry portion 20 further. includes a viewing aperture 51 which rotates therewith for exposing individual indicia 53, Le. 0-20-40-60-80-100, located on the elongate cylindrical extension 14 to provide the smoker with an indication of the percentage of smoke ,to air passing to the mouthpiece 12, e.g. 60 percent smoke and 40 percent air. Some of the air which enters through the above noted circumferential gap will pass through the aperture 51, and will flow to the inlet 44, in use.
During disassembly of the smoking device 10, the smoke entry portion 20 and mouthpiece 12 may be readily separated so that the filter cartridge 16 may be removed from the elongate cylindrical extension 14 when the orifices in the orifice. metering plate '18 become clogged or to inspect the filter material 54. It is therefore advantageous to utilize a transparent filter cartridge 16 for visual inspection of the filter material 54 positioned therein. If the filter material 54 is darkened due to tar and nicotine entrapment, the filter cartridge 16 may be discarded and a new filter cartridge inserted into the elongate cylindrical extension 14. The smoking device 10 is then reassembled and ready for-use.

The smoke entry portion 58 includes a longitudinally extending female element 60 capable of mating with an annular groove 62 formed in a spacing element 64. A spring 66 is adapted to be circumferentially positioned about the body portion 68 of the spacing element The spring 66 isretained between the end wall70 of the spacing element 64 and the bent walls 72 of a sleeve 74. The sleeve 74 is capable of being slidably positioned about the smoke entry 'portion 58 and spacer 64.
Referring to FIG. 6, the assembled smoking device 58 is shown including a filter cigarette 76. However, it I i should be understood the smoking device 58, as well as smoking device-l0, may be utilized with regular or J A vertical wall 78 formed in the smoke entry portion v 58 has a canted recess 80 formed therein leading to the smoke inlet 82, so that the engagement of the longitu dinally extending female element 60 with the annular groove 62 in the end wall 70 of the spacing element 64 will not obstruct the flow of smoke from the cigarette, 76 through the smoke inlet 82, see FIGS. 6, 7, and 8.
' The air inlet 84 formed in the vertical wall 78 communicates with one of the longitudinal slots 86 ar-' ranged on the inside surface 88 of the smoke entry portion 58-to provide a supply of air thereto as previously described with reference to FIGS. 1 through 4.
The smoke entry portion 58 also includes a viewing aperture 90 which rotates therewith for exposing individual indicia 53 located on the elongate cylindrical. extension 14 to provide the smoker with an indication mouthpiece 12, as previously described. The sleeve 74 Y also includes a mating hole 92 capable of being aligned 'of the percentage of. smoke to air passing to the Referring particularly to FIG. 9, the cigarette 76 may tive longitudinal movement between the spacing element 64, the smoke entry portion 58 and the mouthpiece 12 attached thereto, and the slidable sleeve 74. The relative movement is obtained by forcing the sleeve 74 to slide rearward over the mouthpiece 12 from its normal position 94, shown in dotted outline, and an eject position 96. The result of this relative movement is that the spring 66 is compressed between the bent walls 72 and end wall 70 allowing the body portion 68 of the spacing element 64 to move into dispensing engagement with the cigarette 76, dispensing the same from the sleeve 74. The smoking device 58 may be readily disassembled for replacement or cleaning of the filter cartridge 16 similarly to the disassembly of smoking device 10.
