摘要： A pipe coupling includes a rigid cylindrical member, a flexible cylindrical member and a hose clamp. The flexible cylindrical member includes a central tubular member within the rigid cylindrical member. A flexible sleeve extends beyond the rigid cylindrical member and has an inside diameter that is complimentary to a pipe. The sleeve has a first position in which the sleeve is folded back onto the rigid cylindrical member and a second position in which the sleeve is unfolded so as to envelope an end of the first pipe. The central tubular member includes a ledge that has an inside diameter corresponding to an inside diameter of the pipe.

摘要： A firestop coupling assembly for allowing the passage of utility members through a hole in a partition while preventing the transmission of fire and smoke through the hole. The coupling assembly includes a coupling and a firestop extension. The firestop extension has a housing with an inner passageway. Intumescent material is mounted in the inner passageway of the housing. The firestop extension is mounted on the coupling such that the intumescent material extends downward beyond a second end of the coupling. When the coupling assembly is exposed to heat, the intumescent material expands into the inner passageway of the housing of the firestop extension and blocks the second end of the housing of the coupling which prevents the transmission of smoke and fire through the coupling assembly.

摘要： A fire transmission prevention system (10) for use in a drainage system (100) to prevent the transmission of smoke and fire through the drainage system. The system is intended to be used in drainage systems in multi-story structures. The system includes a firestop (16), couplings (14, 26 and 30) and an air vent (42). The firestop prevents fire and smoke from moving through the inner passageways (44D) of the pipes (12, 24, 28 and 72) of a drainage system by blocking the inner passageway of the pipes with a fire resistant plug (20). The couplings are mounted in the floor (102) of the structure and are constructed and secured in the floor such as to prevent fire and smoke from passing around the couplings between the couplings and the floor. The air vent is provided in a vent pipe (40) of the system above a trap (38 or 78) of the system. The vent acts to prevent ambient air and thus, oxygen from entering the inner passageway of the pipes of a system when positive pressure, such as that caused by high temperature and fire, is present in the inner passageway of the pipes.

摘要： An improved trap fitting assembly (10) which prevents the spread of smoke and fire through a floor (100) and ceiling (104) supported by a joist (102) in a building is described. The fitting is preferably adapted for mounting in a tub box (12) and uses a flammable T-connector (24) for draining a tub (106) through an overflow pipe (22) and a drain pipe (20) connected to a tub drain (42). The T-connector is mounted inside of a non-flammable threaded nipple (16) which is mounted in an opening (14) in the tub box by jam nut (26) and a ring gasket (28). A non-flammable J-pipe (30), filled with water to a level L--L, threads onto a lower extension (16b) of the nipple and prevents smoke and fire from spreading through the fitting assembly.

摘要： An improved trap fitting assembly (F.sub.1, F.sub.2) which prevents the spread of fire and smoke through a floor (100,200) of a building is described. The fitting uses a flammable coupling (10, 30) and a non-flammable sleeve (14, 32) inside the coupling with an extension (14b; 32b) from a lower most portion of the floor which is connected to a non-flammable J-pipe (16, 34). In use the J-pipe contains water (101, 201) at a level (L-L) prevents the fire and smoke from going through the floor. The trap fitting is preferably adapted for a floor drain outlet (11) or tub (203).

摘要： A waterproof sleeve coupling for use in a partition for preventing liquid from leaking through a penetration in the partition either adjacent to or through the sleeve coupling. The sleeve coupling has a flexible water stop mounted in sealing contact with a sleeve so that a waterproof seal is formed between the water stop and the sleeve. The sleeve coupling optionally includes an extension coupling and an extension sleeve mounted on the sleeve. When the sleeve coupling is mounted in the partition, the extension sleeve extends beyond the surface of the partition to prevent liquid on the surface of the partition from leaking into the passageway of the sleeve coupling.

摘要： A valve for use in a floor drain to prevent the backflow of fluids from the drain system. The valve includes a valve member and a collar. The first end of the valve member is mounted to the outer surface of the second portion of the collar. In the normal position, the sidewall of the valve member at the second end of the valve member is curled and the valve is in the closed position. When a preset amount of fluid pressure is provided through the collar to the first end of the valve member, the sidewall of the valve member flexes to an open position forming an inner passageway between the ends of the valve member.
