SPECIFICATION forming part of Letters Patent No. 448,988, dated March 24, 1891.
Application filed February 11, 1890. Serial No. 339,988. (No model.)
To all whom it may concern.
Be it known that I, JOHN C. MCGOWAN, a citizen of the United States, residing at Vvvashington, in the District of Columbia, have invented certain newand useful Improvements in Systems of Sewerage; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it io appertains to make and use the same.
My invention relates to a system of sewers for drainin glow ground, and especially to that class of sewers which are for various reasons incapable of carrying oit the water at certain r 5 times. A
My invention is more particularly designed for that class cf cities and towns which are the subject of occasional or frequent flooding of a part or parts of their territory. These zo floods are due to many causes-chokin g of the sewers due to insufficient fall, cross or intercepting sewers emptying` into sewers of little greater capacity than themselves, sewers emptying into tidal waters below the high-tide 2 5 mark, and the backing of water into sewers from neighboring streams or bodies of water due to unusually high tides7 the wind, and fioods or freshets. x
The object of my invention is to providea 3o system of sewerage which will remedy all of these defects; and to that end the nature of the invention consists of constructions and combinations, all as will hereinafter be described in the specification and pointed out 3 5 in the claims, reference being had to the accompanying drawings, in which- Figure l represents atransverse section of a sea-wall having a conduit and subway; Fig. 2, a section of a sewer; Fig. 3, a section of a sewer on line 3 3, Fig. 4; Fig. 4, a longitudinal section on line at et, Fig. 3; Fig. 5, a section of the conduit, showing the preferred manner of connecting the lateral sewers with the same; Figli, details showing the valve at the end of the flushing-pipe; Fig. 7, a modification of the flushing apparatus applied to an iron or terra-cotta sewer; Fig. 8, details showing the manner of closing the opening for the iiushing device in an iron or terra- 5o cotta sewer; Fig. 9, a section showing the relative position of the reservoir, the conduit, and the mains; Fig. 10, a plan view of the matter shown in Fig. 0.
The manner of connecting the system depends entirely upon the topography of the country to be drained. There may be one or more reservoirs placed at any desired point or points with conduits extending therefrom to any desired point or points, as the character of the surface to be drained may require or 6o the location of the groundsewers already formed may need.
As it will be impossible to show up anyparticular locality to be drained within the limits of .an ordinary drawing, the drawings in this case merely exhibit the broad idea of the invention and such details as are generally applicable to the system.
A represents a reservoir the bottom of which is considerably lower than the lowest 7o part of the land to be drained. In many localities it may be placed at the lowest part of the ground to be drained, so that the conduits from the higher points may lead to the reservoir with sufficient fallto carry off the water withoutchanging the sewers alreadyin use. In cases, however, where there may be several low places to be drained the conduit must be constructed in such manner that it will be below all the low points and on such 8o an incline that the water will run easily to the reservoir.
In the drawings a conduit A is shown running from a point higher than the bottom of the reservoir, the depth of which is controlled by the nature of the ground to be drained. The capacity of this conduit must be greater than the capacity of all the sewers emptying into it, so that backing of the water in the sewers will be obviated. It is necessary in a 9o system of this kind to have a fall sufficient to take oft the water. The nature of the ground, however, sometimes prohibits the use of afall that will take off to any great extent the solid matter in the sewage, as an increase in the fall sufficient to accomplish that result would necessitate placing the outfall very near the bottom ofthe reservoir, or making the latter of a great depth, which would be very expensive to make and necessitate lifting the sewroo age to a great height before passing it into the place of final outflow. To remedy this a series of depressions or catch-basins cigare y formed in the sewers atshort intervalswhiclf serve as vats for the solid matter, which rests therein until the sewer is flushed artificially,
as will hereinafter be described. This flushing prevents the choking of the sewers and the consequent accumulation of filth, creating unsanitary conditions, which is one of the greatest evils that engineers have to contend with. The same evils exist to a great extent in cities that have land which is difficult to drain because it is below the high water mark.
In the wall of the sewer, above the catchbasins, man-holes a', having curves a2, are placed, so that the sewers and conduits may be entered, if desired, for the purpose of cleaning the sewer; but, as the removal of sewage in the heart of a city is objectionable in a sanitary sense, I prefer to wash all the accumulations of the catch-basins into the reservoir, where they can be removed without endangering the health of a city, and be made into fertilizer at a profit.
Any suitable ,flushing device may be used. The flushing device, however, must be independent of the water of the sewer, as that water would have to be dammed up before sufficient volume could be had to flush a basin. Such a construction would also interfere with the natural flow through the sewer. 'lo obviatethat, theflushing device is separate from the sewer and is supplied with water that has not entered the sewer at all. My preferred form consists of. a pipe 0.3, embedded in the bottom of the sewer or conduit, with the exit end pointing toward the outlet of the sewer or conduit and terminating at the head of the catchbasin and the otherend connected with a suitable water-supply a4 at or near the surface of the ground. The pipe a3 is located at the upper head or end of the catch-basin adjacent to the floor or bottom of the same, so as to form a jet or iush pipe for removing the sediment from the head to the outlet end of the catch-basin in a direction toward the mouth of the sewer, the Water from the jetpipe iiowing or impinging against the bottom or floor of the catch-basin, eectually cleansing the same. The outlet end of the pipe a3 may be provided with a hinged valve a5, which is held in place by a spring a, secured tothe under side of the pipe and bent to contact with the valves a5, as shown in Fig. G. This spring is of such tension as to hold the valve in place until a certain pressure is reached, when it permits the valve to fall and allow the water in the pipe to gush forth into the catch-basin and force the contents of the latter into the next basin, and sov on until the reservoir is reached, and into which it is forced and removed at proper intervals.
To prevent thelow lands from being flooded by the water backing into the sewers because of high tide, freshets, or iioods', a sea-wall of suicient height to be above the high-tide or freshet mark is interposed between the place to be drained and the water that causes the trouble. In this sea-wall a conduit is placed,
and all the sewers leading in that direction are connected therewith, thus cutting olf all connection between the sewers and the water. The conduit will deposit the water into the reservoir, from which it is pumped over the wall into the water. The reservoir is pro'- vided with suitable pumping machinery for this purpose, and in places wherethe seawall is not needed and the character of the country is such that the water will have to be conveyed some distance before it can be emptied into a stream or other body of water a stand-pipe may be used to give the necessary pressure to force the water through the4 pipe.
The flushing apparatus shown in Fig. 7 is designed to be used in small sewers where the placing of the flushing apparatus hereto fore described would be too expensive to use. This device is portable and provided with arms a7, which prevent it from falling through the man-hole opening a into the sewer. rlhe hose is attached to the nipple as, and the water passes through an opening on the opposite side. the weighted en d a holding it in position during this operation;
The sea-wall may be provided with a conduit B for electric-light or other wires and be provided with passages for gas and water pipes.
What I desire to claim as new isl. In a system of sewerage for draining low lands, the combination of a reservoir having its bottom lower than the land to be drained, a conduit or main sewer extending from the reservoir to a point higher than the bottom of the reservoir and having catch-basins arranged at intervals, man-hole openings above the catclrbasins, a jet or flushing pipe located adjacent to the head of each catch-basin, so as to direct its jet or flow upon the sediment at the head of the basin and over the ioor of the latter to wash said sediment out of the basin from its head to its exit end in direction of the mouth of the sewer, and a watersupply for each said jet-pipe independent of the waters in the sewer, substantially as set forth.
2. In a system of sewerage for draining low lands, the combination of a reservoir having its bottom lower than the land to be drained, a conduit or'main sewer extending from the reservoir to a point higher than the bottom of the reservoir and having catch-basins arranged at intervals for each catch-basin, a jet or flushing pipe located at the head of said basin and adjacent to the floor of the basin, a valve on the end of said pipe, and devices for closing said valve and holding it closed until the water-pressure in the pipe opens said valves, substantially as set forth.
In testimony whereof I aiiix my signature in presence of two witnesses.
