Abstract
Abstract A cigarette holder having means for variably diluting the smoke with atmospheric air is disclosed. The new device has an radial passageway of variable cross sectional area connecting the smoke conveying passageway of the holder with the atmosphere and a pressure responsive valve in the smoke conveying passageway between the cigarette and the radial passageway.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
225 words
A cigarette holder or the like comprising a. a mouthpiece member having an inner end portion attached to be gripped by the mouth of an outer end portion, b. a holding member for the cigarette or the like, telescopically assembled to the outer end portion of the mouthpiece member, and rotatably adjustable with respect to said mouthpiece member, c. said holding member having a shouldered cavity for the substantially air tight reception of a cigarette or the like, d. means in said mouthpiece and holding members forming a continuous smoke passage from said cavity to the inner end of said mouthpiece member, e. an elastomeric pressure-responsive smoke passage restricting element received in said passage on the downstream side of said cavity, f. said passage restricting element being operative normally to at least substantially restrict said smoke passage and being responsive to pressure differential between its upstream and downstream sides to open said passage progressively in response to increasing pressure differential, and g. cooperating air passage means in the telescoped portions of said mouthpiece and holding members, located on the downstream side of said passage restricting element, h. the respective air passage means in said mouthpiece and holding members being adjustable into at least partial registry to accomodate the controlled entry of air into same smoke passage on the downstream side of said passage restricting element.
Claim 2
Dependent Claim
225 words
A cigarette holder or the like comprising a. a mouthpiece member having an inner end portion attached to be gripped by the mouth of an outer end portion, b. a holding member for the cigarette or the like, telescopically assembled to the outer end portion of the mouthpiece member, and rotatably adjustable with respect to said mouthpiece member, c. said holding member having a shouldered cavity for the substantially air tight reception of a cigarette or the like, d. means in said mouthpiece and holding members forming a continuous smoke passage from said cavity to the inner end of said mouthpiece member, e. an elastomeric pressure-responsive smoke passage restricting element received in said passage on the downstream side of said cavity, f. said passage restricting element being operative normally to at least substantially restrict said smoke passage and being responsive to pressure differential between its upstream and downstream sides to open said passage progressively in response to increasing pressure differential, and g. cooperating air passage means in the telescoped portions of said mouthpiece and holding members, located on the downstream side of said passage restricting element, h. the respective air passage means in said mouthpiece and holding members being adjustable into at least partial registry to accomodate the controlled entry of air into same smoke passage on the downstream side of said passage restricting element.
Claim 3
Dependent Claim
68 words
A cigarette holder according to claim 1, further characterized by a. said passage restricting element comprising a disc-like section of flexible neoprene disposed transversely across the smoke passage and having a portion elastically distortable in response to pressure differential to partly open said smoke passage, and b. a ring-like retaining element being received in said smoke passage to retain said restricting element in its operative, transversely disposed position.
