Abstract: The hose reel apparatus includes a tube motor having a housing that at one end is bolted to a mounting bracket leg to extend within the reel drum and a motor shaft extending within and connected to one end portion of a sheath tube which is also extends within the drum. The opposite end portion of the tube is connected to the reel side plate which is adjacent to the above mentioned leg to rotates the reel. Swivel mechanism is mounted to the other mounting bracket leg, and extends into the drum and is adapted to be non-rotatably connected to a conduit and to a hose that is to be wound onto and unwound from the reel drum.

Abstract: An emergency exhaust system is couplable to a vehicle for conducting exhaust fumes from the vehicle exhaust pipe to an enclosure ventilation system to be exhausted from the vehicle enclosure when the vehicle is normally parked when not being used. The exhaust system includes an elongated flexible hose assembly that is connected to the ventilation system and to an adaptor conduit which at its terminal end has a ring mounting electromagnets for magnetically attaching to a mount plate dependingly secured to the vehicle to have the vehicle exhaust pipe extend therethrough. An intermediate portion of the hose assembly is connected through a balancer assembly to a trolley movable along a rail in a forward direction as the vehicle moves to exit the enclosure. As the trolley moves adjacent to the rail front end, through automatic controls, the magnetic coupling to the mount plate is disengaged.
