IINIIS STATES PATENT PARKE T. SNYDER, 0F CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO ROSS J'. BEATTY, OF CHICAGO, ILLINOIS.

FLUME.

T0 all whom it may concern Be it known that I, PARKE T. SNYDER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Flumes, of which the following is a specification.

My invention relates to improvements in metallic flumes.

One of the objects of my invention is to provide a flume that can readily and quickly be made or built up of a series of sheets of metal, each sheet constituting a section whose longitudinal sides practically meet, thereby providing a flume that is substantially a complete cylinder, in so far as its functions as an open flume are concerned.

In a copending application for flumes, iiled by me March 31, 1918, and identified by Serial No. 757,733, I have disclosed a similar structuremade of a series of sheets of .metal interlapped at adjacent edges to form a joint and secured at the side marginal edges of the lap, at equal distances apart for each sheet, as when the sheets are laid flat, and subsequently bowed into trough like shape, whereby the lapped surfaces are brought into very intimatecontact by thus, subjecting` the outer sheet to expansionstress and the inner sheet to compression stress as the result of the manner of their attachment and the subsequent bowing of the sheets.

My present invention utilizes the same general manner of attachment of the adjacent sheets to form the joint therebetween but employs a more specific means of carrying the joining operation into e'ect.

It furthermore comprises novel and useful means for mutually holding the marginal, longitudinal edges of the structure in position, to provide a flume of more nearly cylindrical cross section.

In the accompanying drawings forming a. part hereof Figure 1 is a plan view of a portion of the completed flume. Fig. 2 is a transverse section, taken on line 2-2 of Fig. 1. Fig. 3 is an enlarged, fragmentary section, taken on line 3-3 of Fig. 1. Fig. 4C is a similar section of a modification.

In all the views the same reference characters are employed to indicate similar parts.

The fiume is made of a series of sheets of suitable metal. such as 5 and 6, preferably tapered in width slightly, so that the adjacent ends, of sheet 5, when properly formed,

may enter into the formed end of sheet 6, in interlapped relation to form a joint.

In Fig. 3 the longitudinal marginal edges of the outer sheet are turned back upon themselves to form a holding means for the adjacent inner sheet. lVhen the sheets are thus formed at their marginal edges, sheet 6 is telescoped within this portion of sheet 5, so that when the structure is bowed, or curved into substantially circular formation, as shown in Figs. 1 and 2, there is no relative circumferential shifting or movement of lthe sheets, and therefore the outer sheet 5 is subjected to considerable expansion strain and the inner sheet 6 is subjected to considerable compression strain, the result of which is that their contacting surfaces at the joints are forcibly pressed together thereby making a completely, watertight joint. This is substantially the method of making the joints described and claimed in my former application, but the means of utilizing these folded marginal edges for the purpose of mutually holding the structure in trough like, or cylindrical form, was not contemplated in my former application.

Fig. S'shows the interlapped relation at the joint of the two sheets wherein a transversely disposed clip 7 having' its ends turned back upon themselves, as at 8, is inserted between the lapped portions of the inner sheet 6, to hold the sheet in substantially cylindrical form. The substantial equivalent of this means of mutually holding the edges of the structure together is shown in Fig. 4, wherein sheets 5 and 6, on one of the marginal edges, are bent back upon themselves and occupy the same relation as the same sheets are shown to occupy on both sides, in Fig. 8, but on the other side of the marginal edge. sheet 6 is bent back over the end 5 of sheet 5, as at 6', and the lappedportions of sheets 5 and 6, on theone side, are inserted between the terminals 5 6 of the other side and the body of said other side, thereby mutually holding the longitudinal edges of the structure together without the necessity of emplovinga clip, such as indicated by 7. The folds of the longitudinal marginal edges of the modified structure. shown in Fig. 4, will operate to produce the same compressing and expanding effects of ythe respective sheets at the joints, as 'shown in Fig; 3.

When arrangement of joining the edges together, as shown in Fig. 4c, is continued be` tween the joints it forms a practically closed structure.

One of the advantages of a closed, or substantially closed, structure is to prevent limbs, leaves of trees, and other debris from falling. into the fiume and it furthermore increases the capacity of the flume and prevents evaporation to some extent.

The folds of the longitudinal marginal.

edges yof the respective sheets may be madev by use of'proper apparatus on the ground upon which the fiume is to be erected so that the sheets may be shipped' from the factory in a perfectly Hat state, in which condition they will occupy minimum space. The structure thereafter may be readily and quickly put together' upon the ground, without the necessity of special tools, and it may be supported by any means usually employed for the support of similar pipe structures. 4

After the sheets have been folded at their longitudinal, marginal edges, and one sheet telescoped within theother and the structure bowed into trough or cylinder like shape itis practically impossible to pull the sheets apart as the compression and expansion strains are so great that the friction effected thereby practically holds the sheets against displacement under any ordinary condition of use.

While the cleat 7 is shown to be relatively short it is evident that it may extend substantially the full length of the sheets and thereby substantially close the opening between the opposite longitudinal edges of the sheet. 1

While I have herein shown a single embodiment of my invention for purpose of clear disclosure it is evident that departure may be made from the specific showing within the scope of the appended claims.

Having described my invention, whatI claim is zy v l. A fiume comprising a series of sheets interlapped at their ends, having( their longitudinal edges folded upon themselves and bowed into cylindrical form, and connected, to mutually hold the structure in shape.

2. A flume comprising a series of sheets, each having its longitudinal edges folded back upon itself, the ends of adjacent sheets interlapped, one within the other, to provide joints therebetween, and bowed into cylindrical shape, and means for connecting the longitudinal edges to mutually hold the e structure in shape.

3. A flume comprising a seriesof sheets, each having its longitudinal edges folded back upon itself, the ends of adjacent sheets interlapped onewithin .the other to provide joints therebetween, and bowed into lcylindrical shape, and cleats engaging the folded edges to hold the structure in shape.

In testimony whereof I hereunto set my hand in the presence of two witnesses.
