Abstract: A device for slowing the burning and smoke output of a resting cigarette between drags thereon by a smoker includes a base with an inclined or sloped open channel therein shaped to closely receive and cradle the burning end of a cigarette around about one-half the circumference of the cigarette. The cigarette is held in a sloped condition with the burning end downwardly. A passage extending along the length of the channel serves to provide air to the cigarette in addition to the air provided by the open side of the channel. The passage is dimensioned to provide a controlled amount of air to the cigarette and the dimensions of the passage may vary along its length to vary the amount of air supplied to the burning end of the cigarette depending upon its position in the channel.

Abstract: A device for extinguishing a cigarette without damaging the cigarette thereby allowing the cigarette to be relit for continued smoking without the bad taste normally accompanying a relit cigarette includes an air compartment with an entrance into the compartment through which the lighted end of a cigarette is inserted. The compartment is configured so that upon insertion of the cigarette, a substantially closed air chamber is formed communicating with the end of the cigarette. The cigarette itself substantially blocks the entrance to the air chamber so that air flow into the chamber, other than through the cigarette itself, is substantially blocked. The air chamber is sized to provide enough air to support continued burning of the cigarette for a preset time, usually about five seconds, after insertion. The invention also includes a device for allowing the cigarette to continue to burn between drags on the cigarette but to reduce the smoke output and rate of burn.

Abstract: A pipe-supporting device adapted to receive and support an exposed pipe on a building roof has a base with a substantially flat bottom for resting on a roof and an upwardly tapered structure secured on and rising from the base to provide an upwardly divergent, substantially V recess having divergent line contacts for receiving the pipe and supporting it above the base. The structure is configured to distribute the weight of the supported pipe substantially equally over the flat area of the base in contact with the roof, and the single line contacts of the V provide this substantially equal distribution of weight regardless of whether the roof is flat or sloped, or regardless of whether the pipe being supported is parallel to the roof or sloped with respect to the roof. Further, the line contacts provide a minimum of resistance to pipe movement so that pipes can easily slide on the device when they expand and contract.
