Specification of Letters Patent.

Patented June 26 19 17.

Application filed February 14, 1916. Serial No. 78,135;

To all whom it may concern:

Be it known that I, ELGIE 0. Anne, a citizen of the United States, residing at Scottdale, in the county of West-moreland and State of Pennsylvania, have invented certain new and useful Improvements 1n Flumes, of which the following is a specification.

My invention relates to the construction of fiumes used in conducting water or. similar liquids from a place of supply to a place of further treatment or use. While not limited to such use the invention more particularly relates to the construction of flumes for use in conveying and aerating or otherwise treating acid mine water.

One object of the invention is to provide a flume of novel construction. having 1mproved means whereby water or other fluid is automatically agitated and aerated and in some cases oxidized during the flow of the fluid therethrough.

A further object of provision of a tures of construction and combinations of parts shown in the drawings and covered by the appended claims and to be more fully described hereinafter.

Referring now to the drawings forming part of the specification, Figure 1 is a lon-. gitudinal sectional side elevation showing a flume constructed and arranged in accordance with my invention.

Fig. 2 is a sectional end elevation on a larger scale, the section being taken on the line II--II of Fig. 1, showing a double compartment flume as constructed and arranged in accordance with my invention.

Fig. '3 is a detail plan on an enlarged scale with part of the cover removed show ing details in the construction of the flume of Figs. 1 and 2.

Fig. 4 is a longitudinal sectional side elevation of the portion of the flume shown in Fig. 3.

Fig. 5 is a top lan of one section of the removable cover orming part of the flume shown in the preceding figures.

The flume illustrated is provided with a vertical partition by which it is separated my invention is the lengthwise into two separate and independ-' ent compartments, and is constructed of wood, although concrete or other suitable building material or combinatlon of maflume having the novel featerials may be .used when found necessary or desirable.

In the accompanying drawings the numeral 2 designates the bottom, and 3 and 4 the side walls of the flume. In the construction shown a vertical partition 5 is provided which extends from end to end of and divides the flume into two separate and independent compartments 6 and 7 Positioned on top of the flume is a cover which is made in sections 2 so as to be removable to enable any particular section to be removed without disturbance of the remaining sections and thereby permit of inspectlon of or repairs to the interior of the flume at any point in the length thereof.

Secured within each compartment 6 and 7 at suitable short intervals in the length thereof, is a series of bottom baffles 8 which.

extend transversely between the opposite faces of the side wall 3 or 4.- and the central partition 5. These bottom baflies extend upwardly with the upper edge 9 thereof termlnating below the top of the-flume and a series of openings 10, which as shown are triangular in outline, are provided in the lower edge of the bottom bafiles to permit of any sludge or finely divided solids beingcarried from one side to the other of the bafiies 8 and eventually to reach. the discharge end 11 of the flume, the bottom of the flume forming thebase or bottom side of the triangular openings.

Between each of the adjoining bottom bafiles 8 is a depending baffle or partition 12 which extends vertically from the top of the flume to a point some distance above the bottom 2. The lower edge 13 of the series of upper bafiies terminates short of the bottom 2, and as shown, the lower edges 13 of the depending baffles 01' partitions are in a plane below the plane of the upper-edges 9 of the series of bottom baflies 8.

The depending baffles 12 near the'upper edge thereof, is provided with a .series of recesses or openings 14, rectangular in outllne as shown, to permit of air passing from one side to the other of the depending baffles without passing beneath these baflies, the air flowing in the direction in which the watcr is carried or from the entrance end 19 toward the discharge end 11 of the flume.

A series of openings 15 is provided in each of the sections 2 of thetop or cover, the

row of openings 15 in each section of the top being located closely adjacent to one of the depending baffies or partitions 12 on the discharge side thereof, the purpose of the openings 15 being to admit air, the flow of which is induced by the'flow of water or other fluid through the flume.

The entrance end 19 'and also the discharge end 11 of the flume is open so as to permit of the free entrance and discharge of the water or fluid conveyed therethrough.

Battens 16 are provided on the sections of the cover or top, and battens 17 and 18' also are provided on the bottom and sides of the flume at suitable intervals in the length thereof.'

In the use of my improved flume it will be located so as to extend lengthwise with its entrance end 19 in position to receive the water or other fluid from the source of supply, and .with its discharge end 11 in position to deliver the treated water or other fluid into the proper tank or receptacle.

When a stream-of neutralized mine water or other fluid being treated is delivered into the receiving end of the flume it will flow therethrough, the bottom 2 being inclined at a sufficient angle to the horizontal to cause the rapid flow of fluid through the compartments. 1

The stream of water or other fluid in flowing through the flume engages with and is backed up by and flows over the first of the series of bottom bafiles 6 and is then engaged and its course obstructed and deflected by the first of the depending baffles or partitions 12 underwhich it passes toward the discharge end of the flume. The water or other fluid is successively engaged by alternate bottom baflles 8 and depending baflles or partitions 12 and is thereby caused to flow through the flume from one end to the other in a tortuous path. Any sludge or heavy solids in the water which become precipitated during the passage of the water through the flume will be caused to pass from one side to the other of the lower series of baflles 8 by the current of water which flows through the openings or pas sages 10 in the lower edge of the lower series of baflies and will be discharged from the end of the flume.

The depending partitions 12 cause an air pocket to form behind each of these partitions and the flowing stream of water'compresses the air in the so formed pockets to a greater or lesser extent, depending upon the velocity of the flowing stream of water,

and causes agitation of the water so that the water becomes thoroughly aerated and, in the case of neutralized mine water, to become thoroughly oxidized in passing through the flume. The rapidly flowing stream of water will also induce the flow of air into the flume through the series of openings 15 provided for that purpose in the sectional cover or top 2*, and in this way cause the air to become mixed with and further aerate and oxidize the neutralized mine water.

The provision of the successive and alternate top baffles 12 and bottom bafiles 8 causes successively difi'erentquantities of air to be intimately mixed with the'water in passing through the flume, avoids the necessity of using mechanical means for aerating and oxidizing the water and avoids the use of a supply of compressed air to aerate the water.

The advantages of my invention will be appreciated by those skilled in the art. The apparatus is simple and will not require frequent or expensive repairs. The fluid in passing through the flume is agitated by and becomes intimately mixed with air and is aerated, and with an acid fluid is oxidized thereby without the use of mechanical means and without interruption of the flow of the fluid.

Modifications in the construction and arrangement of the partsmay be made without departing from my invention. The,

flume may have a single compartment or a series of compartments, instead of two compartments as is shown in the drawings. The construction and location of the openings in the baflles and in the top or cover of the flume may be varied and other changes may be made without departing from my invention as defined in the appended claims.
