WILLIAM LENNON, OF MANI'IOU, COLORADO.

TROUGH OR OPEN FLUME.

17 '0 all whom it may concern Be it known that I, WILLIAM LENNON, a citizen of the United States, residing at the city of Manitou, county of El Paso, and State of Colorado, have invented certain new and useful Improvements in Troughs or Open Flumes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference being had to 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 invention is, however, more especially adapted for use in carrying water for various uses.

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

An additional object is to so construct the joint as to present as little obstruction as possible to the flow of water, or the travel of other material through the trough or flume; and to this end I employ hanger plates, arranged on opposite sides for supporting the flume, the said plates resting on stationary side members as longitudinally disposed sills. The hanger plates project inwardly beyond the sills and the flume supporting members are attached to the inner extremities of the side plates, their inward extension beyond the sills being only such as to subserve this urpose. By virtue of this construction, t e necessity for cross beams or bars extending transversely over the top of the flume is obviated; and there are also other advantages relating both to the function of the apparatus and economy of construction which will readily occur to those skilled in the art to which this invention relates. The disadvantage of the cross bars is that when rubbish, as vegetation of various kinds get into the flume, it catches on these bars, clogs the flume, and causes the water to overflow at the sides.

In my improved construction, I employ clamping members at the Home joints, the

said members engaging the flume sections, both interiorly and exteriorly. The extremities of the exterior members pass upwardly through openings in the hanger plates, their protruding endsbeing threaded to receive nuts for tightening purposes. The extremities of the interior clamping members engage the under surfaces of the hanger plates and are pressed downwardly by the plates as the nuts are turned to tighten the exterior members.

In my improved construction, the flume sections are depressed to form beads, which extend below or exteriorly beyond the outer surfaces of the flume sections, the said beads being interiorly concave and arranged to fit into each other, the flume sections overlapping at the joints.

The interior cavity of the fiume joint is filled by the use of a clam in rod, which as illustrated in the drawing, 15 semi-gram lar or approximately semi-circular in cross section. The exact shape of this clamping rod, however, will depend upon the shape of the interior cavity of the joint, which is to be filled thereby. \Vhile this cavity, as illustrated 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 substan tially remove all obstructions at the flume joints to the free passage or flow of water or other material through the flume or trough. The clamping rod is originally shaped to substantially fill the cavity of the joint, its exposed surface being flush with the interior surface of the flume. Its extremities engage the overlapping inner ends of the hanger plates, which extend downwardly just inside the upper extremities of each clamping rod, thus preventing any possible tendency of the rod to get out of place.

Having briefly outlined my improved construction, I willproceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof.

In this drawing: Figure 1 is a cross section taken through a flume equipped with my improved construction, the fiume joint being shown in elevation. Fig. 2 isa section taken on the line 22, of Fig. 1, the parts being shown on a larger scale. Fig. 3 is a top plan view of one side of the Home. looking down on one of the hanger plates. the direction of the view being indicated by the arrow in Fig. l. the parts being shown on a larger scale than in the last named figure. Fig. l is a vertical section. taken on the line -4. of Fig. o. Fig. 5 is a section similar to Fig. 2. but showing the several elements separated from each other. Fig. 6 is a section. similar to Fig. 2. but illustrating a modified form of construction.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate side sills or beams. which form the support for the flume. To the upper edges of these beams are secured in any suitable manner. as by bolts 0, hanger plates 7. which project interiorlv beyond the side sills and overlap the upper edges of the Home which may be designated in its entirety by the numeral 8.

The flume is composed of sections 9 which overlap each other to form the flume joint-s 10. Referring now more particularly to Figs.

1 to 5, inclusive, of the drawing, let the numeralslQ and 13 designate the overlapping and interlocking bead parts of thetwo fiume sections 9, the said beads being formed by pressing the metal outwardly beyond the outer surface of the flume sections. the two beads being formed to interlock. Each fiume section, as illustrated in the princi pal views, contains a short member 11. extending beyond its bead part. one member 1-1 engaging the inner surface of the cooperating section. whilethe other member 14 engages the outer surface of its companion section. The cavity of the inner bead is filled with a clamping rod 15, whose cross sectional area conforms to the shape of the cavity to be filled, whereby the inner surface of the clamping rod is flush with the inner surface of the trough or fiume. The extremities of this clamping rod engage the overlapping extremities 16 of the hanger plates 7, the said extremities having downwardly projecting lugs 17, the said lugs being arranged in such proximity to the extremities of the clamping rod as to preventthe said rod from getting out of place.

By virtue of the construction just explained, it will be seen, by referring to the drawing, that there is an exteriorly projecting ridge or bead at each flame 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 bead are located carrier rods 18. which are located at the angles formed by the outer bead 12 and the body of the flame section. The extemities 19 of these carrier rods pass through the extremities 16 of the hanger plates, which extend inwardly be yond 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. ('3, the parts of the flume sections which overlap to form the joints are designated Q0 and 91. These parts are the same as the parts 1'2 and 13, except that the ex tensions 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 tiume is made perfectl smooth and uninterrupted at the joints. It becomes necessary. however. to employ an additional member whose center portion is concavo-convex to harmonize with the exterior shape. of the Hume joints. the extremities 23 of this member project ing far enough beyond the head of the joint on the exterior surface of the tlunie to form seats or bearings for the carrier rods 18. which perform the same function as in the other form of construction. The clamping rod 15 is also of the same construction and performs the same function as heretofore explained, when describing the principal views.

From the foregoing description, the manner of constructing 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, I claim:
