METAL FLUME OR TROUGH.

citizen of the United States, rc'siding at Billings, county of Yellowstone, State of Montana, have invented certain new and.

useful Improvements in Metal Flulues or Troughs, of which the following is a specification, reference being had therein to the accornpanying` drawing.

This invention relates to certain new and useful improvements in metal flulnes or troughs, the object being to provide a Iflume which is formed of a plurality of sections having interlocking expansible joints lat their ends whereby the complete flume will be allowed to contract and expand, thereby overcoming the difficulties existing in tlumes now in use.

Another object of the invention is to provide a novel form of hanger whereby the sections will be supported in a rigid manner at their interlocking ends so as to'prevent any danger of sagging or crimping of the fiume by excessive weight.

A further object of the invention is to provide novel mea'ns for clamping theinterlocking sections together whereby an exceedingly tight joint can be formed.

A still further object of the invention is to provide novel means for operating the clamping member whereby the same will be forced firmly into position.

Other and further objects of the invention will be hereinafter set `forth and the novel features thereof defined by the appended claims. In the drawing-Figure 1 is a transverse section through my improved flume or trough; Fig'. 2 is a longitudinal section through the same showing the interlocking connection at the overlapping ends; Fig. 3 is a detail vertical section of a modified form of wedging member for Iforcing' the clam `ing member into position; and Fig. It is a etail View of another form of wedging member.

4Like numerals of reference refer to like parts in the several figures of the drawing.

beads et forming a central portion 5 adapted to receive the end portion 6 of the adjacent section, said section being provided with a similarly constructed bead adapted to interlock or straddle the adjacent bead #t in such a manner. that a slight space is formed between the lrespective interlocking beads in order to allow for contraction and expansion of the sections. The interlocking beads may fit snugly one within the other and the same expansion of the sections be maintained as it will be seen that cach bead of the respective sections has a free movement.

The flume may be supported by any suitable means but is herein shown arranged upon supports S which comprise a base 9 having standards l0 on thel upper ends of which are arranged longitudinal angle irons I11 over which are arranged the angled ends 12 of substantially semi-circular hangers 13 which conform to the configuration of the sections. The hangers 13 are preferably formed of wide' bands, as shown,l of such width that a support is formed for the overlapping ends ot' the respective sections and the beads formed thereon.

The overlapping ends 5 and G of the sections are c amped together' by a clamping member 14 which is substantially se1nicircular in shapeA and comprises a band of such width that it will tit snugly between the beads of the respective sections, the upper ends being normally in a plane slightly above the angled ends 12 of the hangers 13. The clamping member 14 is forced down into position byV wedging members 15 and as shown in Fig. lftlie wedging members are carried by a transverse bar 16, the free end of which extends oveivthe angled ends 12 of the hangers 13, and are provided with openings to receive bolts 17 which pass up through the angle irons 11 and angled ends 12 and are provided with nuts 18 for forcing the bar downwardly thereby forcing the clamping member into position.

In Fig. 4, a' slightly modified form of i clamping member is shown which comprises a T-bary 19, the ends of wluch are flattened and shaped to form wcdging members 2() adapted to engage the clamping member 14 in a similar manner to .the-wedging members 15.

In the modification lshown in Fig. 3, a

wooden support 2l is shown over which is arranged the angled end 22 of a hanger 23 which is bolted inv positionas shown at 24;

member 14: by tightening the nut 28 carried by the bolt 25 whichwill securely lock the overlapping portions of the flume sections in a similar manner to the wedging member previously described. In this construction, it will be seen that the hangers are secured to the wood support and the wedging members so arranged and mounted that they will force the clamping member in such a manner that all danger of the same moving in any way is prevented and at the same time a thune is formed with an unobstructed passage.

lllaving described my invention and set forth its merits what Iclaim and desire to secure by Letters Patent isl.y A iiume having overlapping ends provided with interlocking expansible beads,1 and means for clamping the overlapping ends of one side of the interlocking beads.

2. A flume comprising semi-cylindrical sections, one end of each section being providedwvith spaced semi-circular beads, the other end of said section having a single semi-circular bead adjacent its end.

3. In a device of the kind described, the combination with two sections having interlocking ends, ot a hanger arranged under.'

said interlocking ends, a clamping member ttor engaging said sections to one side of the interlocking ends and holding said sections in interlocked position, and wedging members for forcing said clamping member 'into position.

4. n a device or" the kind described, theA combination with two sections having overlapping ends and provided with interlockf. ing beads7 ofa hanger arranged under said ends, a clamping member for engaging the inner sectionV to one side of its interlocked connection, and a wedging member for forcing and holding said clamping member in position.

5. In a device of the kind described, the combination with two sections having over-v lapping interlocking ends, of a support, a hanger carried o n said support conforming to the conliguration of said sections, a clamping member arranged against the inner face of the inner section'. to one side of the interlocked connection," and Wedging members for forcing said clamping m'ember,

in position.

6. A flume or trough formed of a plurality of semi-cylindrical sections having overlapping ends, one end of each section being provided with spaced transverse semi-circular beads, the other end of said section having a semi-circular transverse bead adapted to straddle the end bead of the adjacent s'ection, and clamping means for holding said sections together.

7 In a device of the kind described, the combination with. semi-cylindrical sections having overlapping and interlocking beads at their ends, of a hanger arranged under said sections at their overlapping portions, a support for said hanger, a clamping mem* bei` engaging the inner face of the inner section, Wedging members adapted to engage the free end of said clamping member, and means for operating said Wedging members. l

8. A flume or trough formed of a plurality of sections, each section having spaced transverse beads at one end and a single bead'- adjacent its other end, the free end of one section being adapted to engage the portion between the beads of4 the adjacent sec.

j its end adapted' to straddle the bead at the free end of the adjacent section, and means for clamping the free end of one section be tween the beads of the adjacent section.
