or contraction, due to large changes in tem- I perature.

A further object is to provide a metallic flume in which the various sections are so jointed as to form a substantially continuous surface and thus minimize the friction of the liquid against the sides of the flume.

Another object is to provide a flume with outstanding longitudinally extending flanges, allowing the flume to be conveniently supported and adding materially to the strength and rigidity of the same.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings accompanying this specification and forming a part thereof, the preferred embodiment of our invention is illustrated, in which Figure l is a top plan View of a portion of a flume embodying our invention.

Fig. 2 is a cross sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a view in perspective of the upstream end of a flume section.

Fig. 4 is a view in perspective of the downstream end of the adjoining or continuous section.

Fig. 5 is a sectional view taken on the line 55 of Fig. 1.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, the flume is composed of a plurality of sections, each of which is provided with two dissimilar ends, arbitrarily spoken of as the up- Specification of Letters Patent.

stream or secondary end U- and the down-. stream or primary end D. The upstream end of one section cooperates with the downstream end of the adjacent section to effect a tight and at the same time expansible juncture therebetween.

The end U is formed by cutting the side flanges 5 away from the extreme end of the section and slightly beveling the upperends of the section as at 6. In this connection, it is to be noted that the fiume sections may be other than semi-cylindrical, if it be so desired. The side flanges 5 which outstand from the upper edges of the fiume sections are designed to support the sections and to add considerable rigidity thereto." i Y The downstream end D of the adjacent flurne section is formed by cutting back the flange 5 away from the scction'end." The end is then folded rearwardly'upon itself to form the annular and connected plate 7,

the extremity of which is then folded forwardly'to form the outer annular and connected plate 8. The spaced but connected annular plates 7 and 8 define a socket 9 therebetween which is open or exposed so as to receive the upstream end U of the adjacent section therein. The outermost fold or annular plate 8 extends a distance beyond the extremity of the fold 7 as illustrated in Fig. 4. This provided for the quick and easy assembling of the flume sections and also presents a large bearing surface or area between the meeting and interengaging ends of the sections. The flanges 5 and 5 are provided with the notched portions 10 which coact to define a bolt-receiving opening therebetween.

A metallic rod 11 extends around the outer fold or plate 8 and is provided with the tightening nuts 12 on the extremities thereof which engage the cross bar 13, or

brace and are adapted to draw the rod 11 into rigid and forced contact with the outer fold 8, thus compressing the same against flume is to be so positioned that the direction oi flow the liquid Will be from upstream to the downstream end of each section. The wide bearing surface obtained between the two sections provides for the liquid-tight juncture therebetween, and

which is not in any way destroyed by the expansion or "CORT/1110131011 of the sections truding end of the upstream or primary section may pass readily beneath the flanges The notches 10 in the flanges 5 and 5 cooperate to form at [the ends of the flanges of the respective sections, fingers 50 whirh overlap the outer edge of the binder 11. These fingers 50 not only aid in holding the binder in its arched form, but, as well, serve as supports for the ends of the brace 13.

Having *thus described the invention, what is claimed is r A flume comprising trouglrshaped primary and secondarysections provided along their edges with lateral flanges, the primary section being folded rearwaially and forwardly upon itself to form an exterior transverse socket across the upper edges of which the flanges of the priinary section extend, the extremity of the secondary section beinginserted into the socket, and the upper edges of the secondary section being beveled to permit the same to pass beneath the flanges of the primary secand a binder uniting the ends of the brace,

the flanges of the sections being cut away close to the body portions of the sections to define openings which receive the binder,

and to define at the ends of the flanges of the sections, abutting ringers which overlap the outer edge of the binder and serve at'once as supports for the ends of the brace and to prevent an undue telescoping of the sections and a subsequent closing of the openings.

In testimony that we claim the foregoing as our own, we have hereto aflixed our signatures in the presence of two Witnesses.
