The channels are made in sections, I4 and these Wings are also formed with laterally each about ten feet in length and the curvature projecting flanges-29 along their upper and outer .55 is such as to permit the nesting of onesection edges; The baflie wall is secured in place ata run-off of surface Water into the flume.

joint, as indicated in Fig. 4 by confining the attaching strip 25 between the overlapping ends of the adjoining sections of the channels I2, with the tension rod I6 upon the exterior of the joint compressing the several arcuate, overlapping members together.

To direct water into the inlet end of the channel 12, I provide the head wall 30, shown in Figs. 8 and 9. This head wall is generally similar to the baffle wall 23 and has vertically extending wings 3i projecting at the side edges and obliquely in an upstream direction. An attaching strip 32 similar to the strip 25 is welded to the upper edge of the wall 30 and has integral flanges 33 perforated to receive the ends of one of the tension rods I6. The wings 3| have horizontal flanges 34; along their upper edges and vertical flanges 35 integral with their outer edges and extending perpendicular to the axis of the flume. The head wall is joined to the receiving end of one of the channels l2, as indicated in Fig. l, and to further aid in directing Water into the flume, a fan-shaped apron 36, preferably constructed from asphalt, is formed between the wings 3i and adjoining the outer, end surface of the head wall.

As shown in Figs. 10 and 11, I provide a flared outlet basin 3'! constructed from sheet metal and having an integral strip 38, like the attaching strips 25 and 32, for securing the basin 3! to the outlet end of the flume. Flanges 39 project obliquely down and out from the side edges of the basin 3? and along the outlet extremity of this basin is a bafile wall 40 having wing extensions 4! to anchor the end and guard against the washing away or undermining of the earth beneath the apron. As shown in Fig. 1, to afford branch connections with the straight, main portion of the flume, I provide T-shaped sections 42 of the channel. Y-shaped, but otherwise similar, branches, not shown, are also provided for obliquely extending branch connections. To make the necessary connections at the top and bottom of a back slope or shoulder, elbow sec tions 43 and 44 are provided, respectively of longitudinally convex and concave shape.

In installing my improved flume, the ditch or other location is shaped to approximately the shape of the flume so that the side edges of the latter are at about the level of the ground or slightly below the surrounding ground. The flume is assembled in the ditch and the arcuate tension rods l6 are then placed and inserted in the perforations H and the cross braces I8 are attached and clamped by applying and tightening the nuts I9. As the next operation, stakes 2| are driven into the ground and bolted to the cross bars l8. Similar rods and brace bars l8 are employed in fastening the baffle walls 23, head walls 30 and outlet basins 31 to the appropriate sections of the channels l2. Upon the tightening of the nuts l9 the several joints are made fast and Water-tight. Finally the back fills l5 are formed on the flanges l4 and 39.

These flanges along the side edges of the channels l2 afford wide shoulders or shelves to receive the fills l5, which are preferably sodded to retain them in place and to insure the prompt The baiile walls 23 may be placed at suitable intervals of from about ten to eighty feet. These bafile walls should be placed on the upper surfaces of the lower sections at the joints so that the upper sections may be placed in position easily and the joints completed by employing the tension rods "5. The top or overlapping channel section is applied over the tension rod so as to afiord the necessary downstream lap. The brace bars [8 are constructed from heavy gauge sheet steel, rolled to give adequate rigidity and to provide the flat bearing surfaces for the flume and stakes. The latter may have a similar cross-sectional shape.

My improved flume and ditch lining has been found to be unusually effective in controlling the flow of water along newly graded roads and requires very little maintenance or repair work because of my improved means for preventing Washouts or undermining at the several points where this is likely to occur under the various conditions found in practice. It will be noted that the flume proper has no perforations for bolts or other fastening means in the path of the water along the flume and water-tight joints are formed between sections by pressing the overlapping members together tightly in the embrace of the tension rods l6. By minimizing perforations, I guard against much of the usual deterioration from corrosion and rusting of the metal around the bolt holes which cannot, except at great expense, be protected by galvanizing, as in the case of the main surfaces of the sheet metal. My arrangement of the tension rods l6 secures the further important advantage of greatly facilitating the work of making the connections at the outer and lower surfaces which are inaccessible for the application of ordinary fastening means.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:

1. A flume for conducting surface water comprising, an open channel formed from sheet metal, integral flanges extending continuously from. end to end of said channel and projecting substantially below and from the side edges of the same to be imbedded in the earth, said flanges being of such width and sufficiently imbedded to prevent the undermining of said channel by surface Water and means for anchoring said channel in the earth.

2. A flume for conducting surface water comprising, an open channel formed from sheet metal, integral flanges extending continuously from end to end of said channel and projecting obliquely down and laterally from the side edges of the same to be imbedded in the earth and to direct water into said channel and means extending across said channel and downward at the sides thereof for anchoring it in the earth.

3. A flume for conducting surface water comprising, an open channel formed from sheet metal, integral flanges extending continuously from end to end of said channel and projecting laterally out and down from the side edges of the same to be imbedded in the earth and affording a baflle to guard against the undermining of the channel, rigid bars engaging the top of the channel and flanges, means securing said flanges to said bars and means for anchoring said bars in the earth.

4. A flume for use in newly graded earth comprising, an open channel formed from sheet metal, integral flanges extending continuously from end to end of said channel and projecting from the side edges of the same to be imbedded in the earth, rigid bars engaging the top of said channel at intervals and anchoring stakes driven intothe earth and secured to said bars.

5, A flume for use in newly graded earth comprising, an open channel formed from sheet metal, integral flanges extending continuously from end toend of said channel and projecting laterally from the side edges of the same to be imbedded in the earth, longitudinally spaced beads extending across said channel, rigid bars engaging the top of said channel above said beads and anchoring stakes driven into the earth and secured to said bars.

6. In a flume of the class described, open, channel-shaped, sheet metal sections having overlapping ends, fianges extending along the side edges of said sections to be imbedded in the earth said flanges projecting down. and laterally from the upper edges of said sections, and means for securing said sections together at their junction comprising, a tension rod embracing the outer surface of the joint, a rigid bar extend ng across the top of the sections at the joint, said bar being perforated to receive the ends of said rod and means for tensioning said rod in engagement with said bar and with the overlapping ends of said sections.

7. A flume for conducting surface water comprising, an open channel of laterally arcuate shape formed from sheet metal, integral flanges extending continuously along the side edges of said channel to be imbedded in the earth, inwardly projecting beads formed in said channel and extending across the same, rigid bars engaging the top of said channel, severally above said beads, tension rods embracing the channel in the several beads, said flanges and bars being perforated to receive the ends of said rods, means engaging said bars for tensioning said rods and anchoring stakes secured to said bars.

8. In a flume, an open sheet metal channel formed with flanges extending continuously along the side edges thereof to be embodied in the earth, a bafile wall formed from sheet metal and projecting down into the earth beneath said channel and across the same, said wall having an upper edge fitting the bottom of the channel, means securing said edge to the channel and wing portions of said wall projecting from the side edges thereof and obliquely from the sides of said channel to guard against the undermining of the channel by surface water, said wing portions projecting above said flanges on the channel and being slotted to receive said flanges.
