  • Patent number: 8429833
    Abstract: A restriction sensor system for identifying the existence of blockages in exhaust conduits of clothes dryers. The restriction sensor system may be used as a retrofit system that is capable of being installed on existing clothes dryers. The restriction sensor system may include a fitting configured to be coupled to an exhaust conduit of a clothes dryer and a blockage indicator housing positioned remote from a clothes dryer. The pressure sensing device may be capable of determining changes in air pressure in the exhaust conduit. Once the air pressure present in the exhaust conduit exceeds a threshold air pressure, the pressure sensing device may send a signal to an indicator to generate an alarm, which may be a visual alarm or audible alarm, or both.

  • Patent number: 7731045
    Abstract: A wall outlet box having a plurality of walls defining an enclosure open at the front thereof is provided. The enclosure can include a back, opposing sides, a top, and a bottom. Forward facing edges of the enclosure can define a front periphery with a mounting lip extending therefrom for mounting the outlet box into a wall. At least one port is provided to engage with a dryer exhaust conduit and at least one measurement member extends from an edge of the port. The at least one measurement member can extend to at least a length approximately equal to a length of the protruding exhaust conduit sufficient to securely attach a flexible hose thereto, such that the exhaust conduit may be placed against the measurement member as a template prior to installation and cutting of the exhaust conduit and the outlet box.

  • Publication number: 20070272714
    Abstract: A funnel bucket device for storing, transporting and dispensing liquids, comprised of a housing for holding a liquid, having an opening at an upper surface, a generally concave inclined bottom surface, and having a support system to support the housing when placed on a substantially level surface. The device further comprises an outlet at a low point of the bottom surface, to which a hose is connectable, and a hose storage system operating by wrapping the hose around the housing and securing the hose in place in at least one groove and at least one hose notch, whereby the hose is not caused to be disengaged from the dispensing device or kinked by the action of wrapping the hose around the housing.

  • Patent number: 7210505
    Abstract: An elbow for a dryer exhaust vent conduit. The elbow can have two nestable channel sections, each channel section having a generally C-shaped cross-section, which may be substantially semi-circular. Each channel section has a connection mechanism along at least one side such that the two channel sections are joinable to form a substantially tubular conduit which has a smooth interior surface, reducing friction losses to the airflow speed of the dryer exhaust. Each channel section can be curved in a large radius arc to provide a turn to the elbow, which may extend around a quarter circle to provide a 90° turn to the dryer exhaust vent conduit. Snap fit locking tabs may lock the two channel sections together. Ends of the elbow may fit into or outside adjoining conduit pipes. The channel sections can be nested for ease of transport and storage and can be easily assembled on site.

  • Patent number: 5566706
    Abstract: A siphoning device used to attain the desired level of water in a swimming pool or other like pools of water that are either overfilled from rain water or from overfilling. A small simple plastic tubular device that is designed to connect to a regular garden hose and hang over the pool edge. A vertical soft plastic threaded tubular pick-up pipe exhibiting threads on one end connects into a vertically aimed threaded fitting of the device and extends into the water to be cut-off by user with a knife at the point that represents the users desired level of water for the pool. Upon filling of the garden hose with water and creating a natural gravity siphon action by locating the termination portion of the hose at a point in the yard that is horizontally a few inches or more lower than the desired pool level, water will be pulled or drained through the siphon device until pool water level reaches the level of the soft plastic pipe cut-off.

  • Patent number: 5476183
    Abstract: A dryer rough-in box, comprising planar surfaces including a top, a bottom, a pair of sides and a back. The top and bottom are parallel, as are the pair of sides. The top and bottom extend between and are perpendicular to the sides. The sides are perpendicular to the back. The dryer rough-in box has typically a plurality of ports, for allowing a dryer exhaust vent duct pass therethrough, for allowing flexibility of installation configurations. The box has a lip, for mounting the dryer rough-in box to studs in a wall. The dryer rough-in box permits a dryer to be placed in close proximity to a wall by creating a space for the dryer hose to fit when accordion upon it self.
