Application September 2, 1937, Serial No. 162,091
3 Claims.
This invention relates to a drainage device particularly intended for use upon roofs or the like, for the purpose of draining off rain water, especially when the water accumulates in quantity during severe rain storms, and is an improvement in the drainage device shown in my Patent No. 1,973,321, dated September 11th, 1934.
One of the objects of the invention is to avoid the water which accumulates on the roof from being drained 01T too rapidly so that the sewage system, and consequently the streets are likely to be flooded. The improved structure is such that due to the gradual carrying oif of the accumulated water, the sewage system may operate uniformly to dispose of the water gradually so that the possibility of flooding sewers and streets is avoided.
Another object ofthe invention is to provide a drainage system whereby the rain water is retained on the roof and permitted of uniformly flowing through the drains without forming air pockets in the drain pipes, such as have been found to cause excess pressure, resulting in backing up of the sewage system with resultant overowing of basins, toilets and the like.
More particularly, the invention contemplates the provision of several concentrically disposed pipes or cylindrical members, the inner one of which constitutes an air vent pipe; the central one of which is spaced from both the inner and outer pipes, and the outer one formed with a plurality of openings through which Water accumulated on the roof may flow.
In the accompanying drawing, wherein an embodiment of the invention is shown, Fig. 1 is a vertical sectional View through a drainage device made in accordance with the invention; Fig. 2 is a sectional view on the line 2--2 of Fig. 1, looking in the direction of the arrows; Fig. 3 is a plan view of the central sleeve; and Fig. 4 is a perspective view of the upper portion of said sleeve.
In the structure shown in the drawing, 6 indicates the ordinary drain pipe fitted in the roof l of a building and having its upper end terminating substantially flush with the face of the roof. Supported upon the upper edge of pipe 8 is another pipe 8 which projects for some distance above the roof and has its lower end 9 eX- tending down into the drain pipe 6. Lugs I8, attached to the outer face of the pipe 8 rest upon the upper edge of the drain pipe 6 and are formed with laterally extending portions which project radially from the pipe 8 and form feet which rest upon the top of the pipe 6 Vto thereby support the pipe 8 thereon.
(Cl. 18a- 31) The inner pipe 8 is of smaller diameter than the internal diameter of the drain pipe 6 so that an annular space or opening il is thereby provided between the two pipes and 8, this space forming an outlet through whichv water may pass. Wiers Il are provided at the upper end of the pipe 8. Said wiers are in the form of angular or notch-like openings and are produced by splitting the pipe downwardly at spaced points from its upper end and folding inward'the triangular wings i8 as shown in Figs. 3 and 4. Said inwardly folded wings i8 meet at their inner ends as shown at i9 and form the vent openings 20 at the upper end of pipe 8. The inner ends of the infolded wings i8 are secured to a tube or pipe 2l at the points i9 by being welded or otherwise secured thereto to thereby support said pipe Xedly and concentrically within the pipe 8.
The diameter of the tube 2l is much less than the internal diameter of the pipe 8 so that the tube 2| does not interfere with the downward flow of any Water which may pass through the wiers I1 to pass through pipe 8 and into the pipe 6. Tube 2| is of greater length than the pipe 8 and has its upper end projecting for a considerable distance above the upper end of pipe 8 and also has its lower end projecting down into pipe 6 well below the lower end of pipe 8.
Pipe 8 as Well as the tube 2i carried thereby, is covered by an apertured casing or cage 22 formed with a laterally extending flange 23 which may be attached to the roof l. Adjacent its lower end, the casing 22 is formed with a plurality of relatively small drain apertures i3. Above these apertures a group of larger drain apertures or slots i4 are provided. At its upper end, the casing is formed with arched bars I5 providing the large opening i8 between them.
From the foregoing, the operation of the device will be readily understood. Any relatively small amount of water accumulating on the roof will pass through the small openings I3 and thence flow downwardly through the annular drain opening il, trickling down on the inner face of the pipe 6 in the form oi an annular stream following the course indicated by the arrows shown in full lines in the lower portion of Fig. 1. This annular passage of the stream of Water permits the central portion of the drain pipe 6, the concentric pipe 8 and the tube 2i to act as air passages so that air in the drain may pass upwardly and outwardly through the opening I6 in the casing 22.
Should there be a great accumulation of Water on the roof by reason of a severe or violent storm and water rise above the small openings I3, it will then pass through the slots I4 in greater quantity, and should the water rise still higher, it will then pass through the wiers I'I and down through the pipe 8 and into pipe 6 in a manner similar to an ordinary drain until the amount of water on the roof has decreased to a point well below the top of the inner pipe 8, when the water will then pass out through the annular opening I I as heretofore explained.
When water is entering into the drain in great quantity, it passes through the wiers I'I and down through pipe 8. The extended upper end of the tube 2| will be above the water flow and' it will readily permit the escape of air up through pipe 6 and through the tube 2l as indicated by the dotted arrows in Fig. l. The Vents 2D formed by the infolded wings on the upper end of pipe 8 will also permit the escape of air during the rapid inflow of water through the wiers I'I- and intopipe 8.
What I claim is:
l. A drainage device provided with a drain pipe, a tubular member having an end inserted down into the drain pipe, said member being of less external diameter than the internal diameter of the drain pipe whereby an annular drain opening is formed between the outer face of the tubular member and the inside of the drain pipe, said tubular member having its upper end formed with a plurality of infolded wings forming wiers and forming air Vent openings between the wings, an air vent pipe supported within the tubular member by the infolded wings, and a perforated casing enclosing the tubular member and the air vent pipe.
2. A drainage device provided with a drain pipe, a second pipe of less diameter than the drain pipe seated on the drain pipe and having a portion projecting within the drain pipe whereby an annular drain opening is formed between the second pipe and the drain pipe, the second pipe having wiers formed at its upper end, infolded wing portions on the pipe between the wiers, said infolded wing portions co-operating in the formation of air vent openings at the top of the pipe between the wiers and an apertured casing eX- tendi-ng over and enclosing the ends of both pipes.
3. A drainage device composed of two concentric drain pipes forming an annular drain space between them, the innermost pipe extending upwardly above the outermost pipe, and having its upper end formed with inwardly bent wing portions co-operating to form air vent openings, said pipe having an air vent tube held between the inner ends of the wings and having wiers 1ocated between the wings, and an apertured casing enclosing the upwardly projecting part of the innermost pipe.
