To all whom it may concern,.-

Be it known that I, ABRAHAM L. ADAMS, a citizen of the United States,-and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Knockdown Flnmes, of which the following is a specification.

My invention relates to a knockdown flume for holding and conveying water, the detail construction of which will be fully setforth and described in the following specification.

To enable others to understand my invention, reference is had to the accompanying J drawings, in Which- Figure l represents a broken side elevation ot my improved knockdown flume, whose locking device consists of a series of skeleton frames or binders embracing the four sides of the flume, said binders being shown in a vertical position or unlocked. Fig. 2 is an endelevation of Fig. l. side elevation of the fiume locked. Fig. 4 is an end elevation of Fig. 3. Fig. 5 is abroken side elevation of the iiume, showing the binders locked and also the means whereby the iiume may be extended indefinitely. Fig. 6 is a broken section of the upper side of an open flume and one of its binders. Fig. 7 is an end elevation of the iiume and a modifi'- cation of the binder. tion of one of the flume-boards. Fig. 9 is a broken side elevation lof the nume, showing the corners reinforced by angle-strips, the Whole bound together by means of a metal strap and Wedges. Fig. 10 is an end view of the construction shown at Fig. 9. Fig. ll is a broken side elevation of the ume without the reinforce angle-strips. Fig.' 1 2 is an end View of the construction shown. at Fig. ell. Fig. 13 is an end elevation of the fiume having only three sides.

The construction and operation are as follows:

The sides of the fiume are composed of the boards l, (see Fig. 8,) having the beveled edges la, which beveled edges are the meeting faces of the sides of the fiume when assembled.

As the object of my invention is to construct aflume that can 'ne readily and quickly put together or taken `apart without employaround the exterior. and 6 a-re shown binders consisting of a skele- `nails or screws.

Fig. 3 is a brokenA Fig. 8 is an end eleva-7 'ing nails, screws, or other common mode of fasteningit is necessary to apply a binder ton frame which loosely embraces the exte-l rior of the Hume when in a vertical position, as shown at Figs. l, 2, and 6; but when canted,

as shown at Figs. 3, 4, and 5, the top and bot- 6.o

tom rails 2 and 3 will crowd against the top and floor of the flume. Under this pressure the beveled edges la of such top and bottom acting against the corresponding beveled edges of the sides will force such sides hard against the side rails 4 andv 5 of the binderframes, as shown at Fig. 4, thus Iiruily holding the fiume together Without the use of of another board against the end 1b, asshown 75 at Fig. 5. 6, Fig. 6, is one of a series of strips, also provided with beveled edges to rest against the beveled edges of the side pieces or boards When the top is removed, so as to make an open Hume, if desired. narrow strips are placed directly under the binders and operate in the same Way tospread the side boards of the flume.

In Fig. 7 is shown a modification of the before-mentioned binder-frames. struction the binders are not canted; but the same effect is produced by means of the key or Wedge 7 acting against the tapered side 4 of the binder-frame and one'side of the flume.

Where there is great internal pressure re- 9o quired-as, for instance, in hydraulic mining-I prefer to reinforce the corners of the iume by means of the angle-strips 8, Figs. 9

and'lO. For binders either the skeleton- -frames shown at Fig. 1 or the metal strips or 95 bands 9, Figs.l 9 and l0, can be used. In the latter case the bands are held in position by means of the nails 11, driven into thelongitudinal Wooden strip l2, lying against one side of the fiume opposite the keys 10. This con, loo

tinuous metal binder being thus secured at every turn about the i'lume virtually converts said binder into separate individual bands, so that the tightening effect of each Wedge or In Figs. l; 21 37 17 57 In taking the fiume dovvn all that is necessary is simply to force the 7o These 8o In this conkey is only exerted on that particular metal band with which it is engaged. lhile there is an advantage in using the long strip in the first winding, the wedges will exert a better tightening effect by fastening the hands to the strip 12 at each revolution.

In Figs. 1l and 12 are shown the use of metal bands and keys without the reinforce anglestrips. In some cases it might be desirable to make a tank-like structure with one or both ends closed, as shown at Fig. 12, in which case the end 13 is simply let into the grooves 14, formed on the inside faces of the sides of the iume.` i

The novel feature of beveling the meeting faces of the iop, floor, and side walls of the flume and applying an outward pressure on opposite sides, as indicated by arrows a and b, will, as before meni ioned, produce a resultant force in the direction as indicated by the arrows c d. This peculiar construction is the main feature or gist of my invention, and, as before stated, is applicable to any shape of fiume to which this principle Will apply.

Having thus described lny invention, what I claim as new, and desire to secure by Letters Patent, is- Y l. The herein-described improvement in a knockdown flume having three or more sides each of said sides provided with a beveled meeting face, combined with abinder adapted to envelop all of said sides, for the purpose set forth.

2. The herein-described improvement in a knockdown fiume having three or more sides provided with beveled meeting faces, combined with a binder-adapted to envelop all of said sides, means whereby force is applied to one or more of said sides to produce a resultant force at an angle Lo the initial force so as to crowd the remaining sides of the Hume hard against the binder and thus firmly lock the whole structure togeth r, for the purpose set forth.

3. The herein-described improvement in knockdown flumes having three or more sides provided with beveled meeting faces, anglestrips adapted to reinforce the corners of said fiume,a binder adapted to embrace said anglesr rips, means substantially as shown for loeking the sides of said Hume, for the purpose set forth.

4. The herein -described improvement in knockdown flumes having three or more sides provided with beveled meeting faces, combined with a metal-strap binder adapted to be spirally wound around said sides, a horizontal wooden strip adapted to rest against one side ofthe flume, said metal-strap binder adapted to be secured to such horizontal strip at every turn about the fiume, for the purpose as described and set forth.

Signed at Bridgeport, in the county of Fairfield and State of Connecticut, this 26th day of January, A. D. 1900.
