or Open Flumes; and I dodeclare the ollowing to be a full, clear, and exact description of the invention, such as will enable others skilled-in the art to which itappertains :toniakeand use the same, reference being had itoj the accompanying drawings,

and to the characters of reference marked.

thereon, which form a part of this specification.

My invention relates to improvements in troughs or open flumes adapted for use in carrying material of any kind. The-inventidn.is,.however, more especially adapted for 1156111 carrying water for varlous uses.

My general object is to provide a sheet metal flume composed of sections, the flume joints being formed in such a manner as to make them perfectly tight, while, at the same time, the constructlon is exceedingly economical.

An additional object to so construct, the oint as to present as little obstruction.

as" possible to the flow of the water, or the travel of other material through the trough In my improved construction, the flume sections are depressed to form beads, which extend below orexteriorly beyond the outer surfaces of the fume sections, thesaid beads being interiorly concave and arranged to fit into each other, the fiurne sections overlap ping at the joints.

The interior cavity of the flume joint-is filled 'bythe use-cil a clamping rod, which, as illustrated in the drawing, is semi-circular or approximately semi-circular in cross section. The exact shape of this clamping rod, h6wever, will depend upon the shape of the interior cavity Of tlIBJOlIIt, which is to be filled thereby. VVhile this cavity, as illus trated in the drawing, has the shape of a segment of a circle, it is evident that it may,

if desired, be of other suitable shape, the important advantage of this feature being that it makes it practical to substantially remove all obstructions at the Hume joints to the free passage or flow of water or other material through the fiume or trough. The clamping rod is originally shaped to substantially fill the cavity of the joint, its

exposed surfacebeing'flush with theinterior surface of the fiume. Its extremities engage 'the overlapping inner ends of the hanger plates, which extend downwardly just in of the rod to get out of place.

Havin briefly outlined my improved same indetail, reference being madefto the accompanyin drawing, in which 'is'illiistrated an em odiment thereof- I-nthis drawing: Figure 1 is'a cross section taken through a flume'equipped with my improved construction, t-hefiume joint tion taken on the line 2-2 of Fig. 1, the parts being shown on a larger scale. Fig. 3 is a top plan view of-one side of the flume, looking down on one of the hanger plates, the direction of the View being indicated by the arrow in Fig. 1, the parts being shown on a larger scale than in'the last- ;n'amed figure. Fig. 4 isaj verticalsection, taken on-the line l-a-of' Fig, 3. Fig. is

several elementsseparated from each'other. .Fig. 6 is a section, similar to Fig. 2, but illustrating a modifiedform of construction. The same reference characters indicate the same parts mall the views. Let the numeral 5 designate side sills 0r .beams, which form the support for" the flame. To the upper edges of these "beams are securedin any suitable manner,"asfby teriorly beyond the side sills and overlap the-upper edges of the fl'ume, which may be designated in its entirety by the numeral 8. The flume is composed of sect-ions 9 which overlap each other to form the fiume joints. "l0.

Referring now more particularly to Figs. 1 to 5, inclusive, of the drawing, let the numerals 12 and 13 designate the overlap ping and interlocking bead parts of the two flume sections 9, the said beads being formed by pressing the metal outwardly beyond the outer surface of the flume sectlons, the two beads being formed to interlock. Each-flume section, as illustrated inthe principal views, contains a short member 14, extending beyond its bead part, one member 14 engaging the inner surface of the cooperating section, while the other member 14 engages the outer surface of its companion section. The cavity construct1on,I will proceed to describe the being shown in elevation; Fig. 2 is a see-- a section similar to Fig. 2, b'ut showii-ngthe' 26,191I. s i1n.ee1,ss7.- o antennae side the upper extremities of each clamping rod, thus preventing any possible tendency bolts6, hanger. plates 7, which projectile vent the said rod from getting out of place.

By virtue ofthe construction just explained, it will be seen, by referring to the drawing, that there is an exteriorly-projecting ridge or bead at each flume joint, while the inner surface of the joint is substantially flush with the inner surface of the flume. On opposite sides of this exterior'ridge or head are located carrier rods 18, which are located at the angles formed by the outer bead 12 and the body of the flume section. The extremities 19 of these carrier rods pass through the extremities 16 of the hanger plates, which extend inwardly beyond the side sills, nuts being applied to the threaded extremities of the rods above the hanger plates to secure the carrier rods in place. In the form of construction shown in Fig. 6, the parts of the fiume sections which overlap to form the joints are designated 20 and 21. lhese parts are the same as the parts 12 and 13, except that the extensions 14,, shown in the principal views,are wanting in the modified form of construction, and, by virtue of this omission, the inner surface of the fiume is made perfectly smooth and uninterrupted at the joints. It becomes necessary, however, to employ an additional member 22, Whose center portion is concavo-convex to harmonize with the exterior shape of the flume joint, the extremities 23 of this member projecting far enough beyond the bead of the joint on the exterior surface of the fiume to form seats or bearings for the carrier rods 18, which perform the same function as in the other form of construction. The clampcipal views.

From the foregoing description, the manner ofconstructing my improved trough or flume, as well as the use of the same, will be readily understood and need not be further explained in detail.

Having thus described my invention, what I claim is l. A fiume including side sills, hanger plates secured thereto and extending interiorly beyond the same, flume sections having exteriorly-projecting overlapping and interlocking hollow beads, a clamping rod shaped to till the interior cavity of the bead, the extremities of the said rod abutting against the interiorly-projecting extremities of the hanger plates, and means applied exteriorly to the fiume on each side of the jointand connected with the hanger plates for supporting the fiume in place, the lineof centers of said means assing through said clamping rod, substantially as described.

2. A flame including side sills, hanger plates secured to the sills and projecting interiorly beyond the same, flume, sections having their adjacent extremities equipped with hollow beads arranged to overlap each other in interlocking relation, a clamping rod in the interior cavity of the joint, the extremities of the rod engaging the overlapping extremities of the hanger plates, carrier rods applied to the securing member on opposite sides of the joint bead and secured at their extremities to the hanger plates,said rods being so positioned that a straight line through their centers will pierce the clamping rod substantially at its median line, sub- .stantial y as described.

In testimony whereof I aflix my signature in presence of two witnesses.
