Abstract
ABSTRACT
The sewer system is designed for a building comprising a sewer line and a plurality of plumbing fixtures connected to the sewer line for carrying the discharge sewage from the fixtures into the line. A flexible sewer cleaning cable is permanently installed inside the sewer line. A motor is permanently coupled to the cable and is adapted to selectively rotate the cable inside the sewer line, thereby to prevent material from collecting inside the sewer line. The motor will rotate the cable for time intervals determined by the sewer line characteristics in accordance with a prescribed preventive maintenance program.

AB S TRACT
The sewer system is designed for a building comprising a sewer line and a plurality of plun~ing fixtures connected to the sewer line for carrying the discharge sewage from the fixtures into the line. A flexible sewer cleaning cable is permanently installed inside the sewer line. A motor is permanently coupled to the cable and is ada~ted to selectively rotate the cable inside the sewer line, thereby to prevent material from collecting inside the sewer line. The motor will rotate the cable for time intervals determined by the sewer line characteristics in accordance with a prescribed preventive rnaintenance program.
BACKGROUND OF THE INVENTION
Present day sewer systems for residential, commercial, industrial and hospital buildings comprise a sewer line and a plurality of plumbing fixtures connected to the sewer line for carrying discharge sewage into the line.
In many buildings, homes and con~ercial establishments, such as restaurants, the sewer line gets frequently plugged up requiring the services of professional plumbers and creating a hazard to the sanitary conditions which must be constantly maintained as required by the health codes.
i7S7 In addition, a plugged up sewer line frequently makes a commercial building unusable for its intended purposes and the workers may have to remain idle until the sewer line is unplugged which may take several hours or more, depending on how fast a plumber is available to unplug the sewer line.
The above problems with conventional sewer systems can be remedied in accordance with the invention by desiyning a sewer system which permanently incorporates a sewer line clean-ing cable therein which is periodically and preferably automatically operated.
SU~ RY OF THE INVENTION
According to the present invention there is provided a system for cleaning the sewer line of a building, the sewer line having a plurality of plumbing fixtures connected thereto, the system comprising: a cleaning cable permanently installed in the sewer line, said cleaning cable beïng permanently distorted at points along its length in alternate directions about an axis transverse to said length and being flexible along the remainder of its length such that said cable can con-form to bends in the sewer line and can conform to a spiralupon rotation; and drive means for rotating said cable such that said cable cleans out such sewer line, said drive means including a drive system having a rotating output and coupling means for connecting said cable to the rotating output of said drive system.

DETAILED DESCRIPTION OF THE I~VENTION
In Fig. 1 is shown an illustrative sewer system, such as exists in a restaurant. The system is generally designated as 10 and comprises a plurality of fixtures, such as sinks 12, which discharge sewer liquid through vented feeder pipes 14 typically mounted in the walls of a building 16. The pipes 14 are connected to a common sewer line 20 for the building 16.
Line 20 is typically under the main floor 22 of the buildj.ng.
In a restaurant installation, before the sewer line 20 is connected to the city main 24 (Fig. 4), it passes through a grease trap 26 or a clean out 28.
In accordance with the invention a typical sewer installa-tion is combined with a sewer cable line, generally designated as 30, which is permanently installed in the sewer line.
~5~
Cable 30 is made of interwoven steel wire and has a dia-meter of about l/2"~ Cable 30 is kinked at spaced intervals D, say about l foot apart, with kinks have an angle A of about 10.
Cable 30 is connected through a coupler connector 32 (Fig. 2) to the output shaft 34 of a reduction gear box 36 of conventional design. The input shaft of gear hox 36 is connected to the output shaft of an electric motor 38.
Motor 38 is energi~ed from an electric main 39 through a switch 41.
In the preferred embodiment, switch 31 is connected to the motor 38 through a conventional timer 40 which can be manually programmed. Such timers are used, for example, on television recorders D
Motor 38 is geared down by gear box 36 to about 30 rpm which provides optimum cleaning efficiency for typical grease lines or sewer lines. The 10 kinks on the 1/2" sewer cleaning cable 30 help to completely clean out the sewer line, thereby preventing sewage material from collecting inside the lines being cleaned. The timer 40 will be turned on automat:ically in accordance with a desired preventive cleaning schedule and will energize the motor for a time interval determined by the sewer line characteristics and the particular loads carried thereby.
It will be appreciated that a main advantage of the present invention resides in preventing sewer line plugging from occurring in the first instance, thereby saving repair costs which can be substantial on an annual basis, as well as preventing the idling of workers in business establishments.
