4 Claims.
This invention relates to new and useful improvements in drainage tubes, and has for its principal object the provision of a specially constructed drainage tube having inlet openings protected in such a manner as to prevent the entry of sand or silt to said tube while admitting liquid thereto.
Another object is the provision of-a drainage tube formed to present passageways for the entry of fluid, the outer ends of said passageways being disposed below the inner ends thereof, lhgreby necessitating that fluid rise to enter said Another object is the provision of a drainage tube having inlet ports formed adjacent the upper portion thereof, and being formed to present members overhanging and extending below said inlet ports.
Still another object is the provision of a drainage tube comprising a channel and a cover member extending outwardly beyond the edges of said channel and forming passageways in combination with said channel through which fluid must rise to enter said tube.
Other objects are simplicity and economy of construction, and adaptability of the parts when disassembled to be nested compactly for economical storage and shipping.
With these objects in view, as well as other objects which will appear in the course of the specification, reference will be had to the drawings, wherein:
Figure 1 is a vertical section adjacent the curb of a street, showing a street drainage system employing a drainage tube embodying the present invention.
- resilient engagement of the parts.
Fig. 2 is a plan view of a drainage tube embodying the present invention.
Fig. 3 is a fragmentary section taken on line III-III of Fig. 2.
Fig. 4 is an enlarged transverse section taken on line IV-IV of Fig. 2.
Fig. 5 is an enlarged transverse section taken Fig. 10 is a transverse another modified form of the tube wherein the channel and cover portions are joined by the Fig. 11 is an inverted plan view or" the tube shown in Fig. 10.
Like reference numerals apply to similar parts throughout the several views, and the numeral It refers to a drainage tube comprising a channel l8 of anydesired cross-section, the edges of said channels being bent to form outwardly and downwardly extending flanges 20, and a transversely corrugated cover member 22 having its edge portions turned downwardly so that the bottom edges of the corrugations lie against flanges 20, and so that the under valleys 24 thereof form passageways 26 in combination with said flanges It will be noted that cover members 22 extend outwardly past the outer edges of flanges '20, thus providing an overhangprotecting the outer ends of passageways 26 and preventing the direct packing of earth or sand in said openings.
As is seen in Figs. 6 and '7, channels l8 and cover members 22, when disassembled, may be compactly nested for economical use of space in shipping and storage. In assembly, tabs 23 struck from flanges 20 at spaced intervals therealong, said tabs being left in the flat during storage, are projected through cover member 22 and bent overv to secure said cover member clampingly to said flanges. It is contemplated that sections of said tubing shall be butted together and secured against relative movement by the following means; The cover member 22 is spaced apart from the ends of channel 13 asshown in Fig. 3, so that when the channels are in abutted relation as shown, the ends of the adjacent cover members will be spaced apart. A two-piece band connector 56 comprises a U-shaped member 32 having outturned ears 34 and adapted to overlap the joint between the channels with the cars 34 resting against the flanges 20, and a corrugated strip 36 adapted to overlap adjacent cover members and to extend across the space .therebetween. The corrugations of stripSt are adapted to register with corresponding corrugations of cover members 22, so that when screws 38 are inserted to join the end portions of strip 35 and U-shaped member 32, as shown in Fig. 7, the abutted tubes will be rigidly retained in aligned relation.
As is plainly shown in Figs. 4 and 5, when the tube is buried the outer or inlet ends of passageways 26 are disposed below the inner ends, and
cross-sectional view of consequently fluid must rise through said passageways. Since the velocity of flow through said passageways is ordinarily low, sand, dirt, silt, etc. entrained in the fluid is allowed to settle out and only relatively clean fluid is allowed to enter the tube. In ordinary drainage tubes without inlets so disposed, sand and silt enter the tube ireely, and a comparatively short time the tub'e nfiafy become so full as to be virtually useless. Thus the usefulness of the tube is greatly increased.
One application of the drainage tube is illustrated in Fig. 1, showing a transverse cross section at the curb line of a street 1}, trench 4a is dug along the curb line, a drai age meets laid along the bottom thereof, and the trench filled with loosely packed material 4!; such as sand, gravel, or the like. The curbing ii is supported on said sand the footing 44 til-steer being narrower than the trench. The paving has It is spaces ai art fro'inthe curbing at is topermit water draining 'fro'in the slab to flow into the sand 4]; Water draining through soil between the curbing and sidewall; 51? also enters the sand. The water then flows through thesandbygravity, enters tube it as previously described; and is conducted thereby to any point si 'Inthe meningeal-iii Shawn in Figs. 3 andil, the drainagetube 52 is erm-ea of a single sheet oi metal; the opposite edgesthereof being bent tqieiiri abutting flanges 54 joined by any suitable means such as by ivets 58; I Said tube is form t pre en enem t id v i extending nstants opposite upper e es. a p lurality'of hoies star io'i ined through the inner rape or safe lip s adjacent the juncture of saw. lips w t the chahnel portion s? ar the tube. regene ates ubs n lli id n al s e of the tram-e ema water being required to rise from the lowerjedges of lips 58 to the level W ioreentering the tube.
