Abstract
Abstract An improved smoking device for metering a predetermined and selectively variable ratio of smoke and air to a smoker. An elongate cylindrical extension, including a filter cartridge, is connected to a mouthpiece for insertion within a smoke entry portion. The elongate cylindrical extension includes a radial locking means for engagement with a positioning means of the filter cartridge to prevent radial movement of the filter cartridge relative to the elongate cylindrical extension means; longitudinal mating means for holding the mouthpiece and smoke entry portion longitudinally while allowing relative rotational movement; circumferential engaging means cooperating with the radial locking means to allow the smoke and air inlets in the smoke entry portion to be held in axial alignment with a selected pair of orifices in an orifice metering plate; and means for urging the orifice metering plate into uninterrupted contact with the smoke inlet. The smoking device may advantageously include an improved cigarette ejection means.

Total Claims: 11
Claim 1
Independent Claim
257 words
Improved smoking device of the type for metering a predetermined and selectively variable ratio of smoke and air to a smoker, said smoking device including a cylindrical smoke entry portion having means providing an air inlet and a smoke inlet, a mouthpiece with a smoke withdrawal chamber, and a filter cartridge, wherein the improvement comprises: an elongate cylindrical extension connected to said mouthpiece and extending longitudinally therefrom, said elongate cylindrical extension having a diameter slightly less than said smoke entry portion for insertion therein; said filter cartridge adapted for insertion into said elongate cylindrical extension and including a front portion having an orifice metering plate and an opposite portion having at least one hole arranged therein, whereby smoke and air may flow through said filter cartridge from said orifice metering plate through said end portion, said filter cartridge also including a positioning means; angular locking means associated with said elongate cylindrical extension for engagement with said positioning means to prevent angular movement of said filter cartridge relative to said elongate cylindrical extension; and longitudinal retaining means for holding said mouthpiece and smoke entry portion longitudinally while allowing relative rotational movement, whereby said filter cartridge may be angularly fixed in said elongate cylindrical extension and said smoke receiving portion positioned therein and held longitudinally fixed, while said mouthpiece and said smoke entry portion are capable of undergoing relative rotational movement so that a selected pair of orifices in said orifice metering plate may be aligned with the smoke inlet and air inlet means in said smoke entry portion.
Claim 2
Dependent Claim
257 words
Improved smoking device of the type for metering a predetermined and selectively variable ratio of smoke and air to a smoker, said smoking device including a cylindrical smoke entry portion having means providing an air inlet and a smoke inlet, a mouthpiece with a smoke withdrawal chamber, and a filter cartridge, wherein the improvement comprises: an elongate cylindrical extension connected to said mouthpiece and extending longitudinally therefrom, said elongate cylindrical extension having a diameter slightly less than said smoke entry portion for insertion therein; said filter cartridge adapted for insertion into said elongate cylindrical extension and including a front portion having an orifice metering plate and an opposite portion having at least one hole arranged therein, whereby smoke and air may flow through said filter cartridge from said orifice metering plate through said end portion, said filter cartridge also including a positioning means; angular locking means associated with said elongate cylindrical extension for engagement with said positioning means to prevent angular movement of said filter cartridge relative to said elongate cylindrical extension; and longitudinal retaining means for holding said mouthpiece and smoke entry portion longitudinally while allowing relative rotational movement, whereby said filter cartridge may be angularly fixed in said elongate cylindrical extension and said smoke receiving portion positioned therein and held longitudinally fixed, while said mouthpiece and said smoke entry portion are capable of undergoing relative rotational movement so that a selected pair of orifices in said orifice metering plate may be aligned with the smoke inlet and air inlet means in said smoke entry portion.
Claim 3
Dependent Claim
88 words
Improved smoking device as claimed in claim 1 wherein: said smoke entry portion has means providing a plurality of grooves longitudinally arranged on the inside surface thereof, said plurality of longitudinal slots being equal to the number of orifices in said orifice metering plate; and said elongate cylindrical extension includes groove engaging means for radial engagement with said groove means and cooperating with said radial locking means to allow said smoke inlet to be angularly held in axial alignment with the selected orifice in said orifice metering plate.
Claim 4
Dependent Claim
47 words
Improved smoking device as claimed in claim 1 wherein: said elongate cylindrical extension includes resilient means for urging said orifice metering plate into contact with said smoke inlet means, whereby said smoke inlet and a selected orifice form an uninterrupted conduit for the transmission of smoke therethrough.
Claim 5
Dependent Claim
30 words
Improved smoking device as claimed in Claim 3 wherein: said resilient urging means includes a plurality of resilient arms positioned for engagement with said front portion of said filter cartridge.
Claim 6
Dependent Claim
36 words
Improved smoking device as claimed in claim 1 wherein: said longitudinal retaining means includes a peripheral ridge arranged circumferentially about said elongate cylindrical extension and means providing a mating circumferential recess within said smoke entry portion.
Claim 7
Dependent Claim
66 words
Improved smoking device as recited in claim 1 wherein: said smoke entry portion includes means providing a viewing hole; and said elongate cylindrical extension has indicia circumferentially positioned thereon indicating the percentage of smoke to air being transmitted to the smoker, whereby when said mouthpiece and smoke entry portion are rotated relative to one another an individual indicia will be visible through said viewing hole means.
Claim 8
Dependent Claim
52 words
Improved smoking device as claimed in claim 1 wherein: said air inlet means is arranged for communication with one of said plurality of longitudinal slots, whereby air may be transmitted to said air inlet and mixed with the smoke entering through said selected orifice to provide the desired smoke to air ratio.
Claim 9
Dependent Claim
24 words
Improved smoking device as claimed in claim 1 including: means for ejecting a spent cigarette to allow said smoking device to receive another cigarette.
Claim 10
Dependent Claim
72 words
Improved smoking device as claimed in claim 1 including: a spacer arranged for mating engagement with said smoke entry portion; a sleeve slidably positioned about said spacer and said smoke entry portion for rotational movement therewith, said sleeve capable of being longitudinally moved relative thereto; and biasing means engaging said spacer and said sleeve for moving said spacer and said smoke entry portion relative to said sleeve after ejection of a cigarette.
Claim 11
Dependent Claim
36 words
Improved smoking device as claimed in claim 9 wherein: said smoke inlet means is canted with respect to the central longitudinal axis of the device, to permit the flow of smoke into said smoke entry portion.
