PLUME CONSTRUCTION.

hotesse.

To all whom t may concern:

Be it known that I, Ci-nnnins VfGH/ire,

a citizen of the United States, and residing in the city of Los Angeles, count-y of Los Angeles, State of California, have -invented a new and useful Improvement in.

Flume Constructions, of which the following is a specification. l Y to flume constructions and particularly to providing a flume of reinforced concrete, and the principal object of the invention is to provide a construction which will utilize discarded cables which have become somewhat worn and are no longer considered suitable for conveying work. Y

It is also an object to provide such a fiume construction with adjustable brackets by which the cables may be suitably supported in relation to the surface over which it is desired to carry the fiume.

lt is a further object to provide a concrete fiume construction with a reinforcement in theform of wire netting or expanded metal which can be readily secured, by means of suitable lashings, to the supportinO" cables.

In the drawings, Figure 1 is a view of a flume showing the supports used to carry the same over uneven surface of the ground. Fig. 2 is an enlarged detail cross-section of the flume and one set of its supports. Fig. 3 is a longitudinal detail of a portion of the upper edge of the reinforcement and the cable, a portion of the cement structure being included. Fig. 4 is an enlarged detail showing the cross-section of the cable and a small portion of the reinforcement and the lashing therefor.

More specifically in the drawings, the numeral 5 designates the surface of the ground over Vwhich the flume 6 is supported by means of the vertical uprights 7, placed at suitable intervals and braced by means ofl the diagonal timbers 8. The uprights 7 are preferably provided with a vertical bore 9 forming a socket within which the supporting rods 10 are adjustably mounted, this adjustment consisting of the threaded shank 11 of the metal support, provided with the adjusting nut 12 which engages with the washer 14 resting on the top of the timber supports.

The upper ends of the rods 10 are preferably bent at'rightV angles to the shank 11 and extended to provide an ear l5, through Specification `of Letters Patent.

which a bore is carried of sufficient size to engage the cable 16.

The cables commonly used for the purposes mentioned are formed of wire of `a number of strands, and the rods 10 are strung on one end and carried along to the supports, which are placed at the required interval to form the size flume desired.

To form a reinforcement for the flume, which, as shown, is preferably semi-circular in cross-section, a strip of expanded lath or wire netting 17 is used extending from the lower portion of one cable, in the proper configuration, to the opposite and parallel cable 16, the netting 17 being secured by suitable lashings, preferably of metal, shown as rings 18 mounted on the cables 17 and engaging with the edge of the strand of the netting.'

By use of suitable forms, or by simply troweling a sufficient quantity of cementitious material 19 in engagement with the netting, the fiume is formed, this material being preferably carried up over the cable, as shown, at the point 20, so that all the. metal parts are covered by the cementitious material and the bars 10 are included from the point 21 inwardly. By this means, fiumes can be quickly and economically constructed in sections where suitable materials to form a support therefor are difficult to obtain and expensive in character, as well as utilizing cables which have become practically worthless and are not of sufiicient value to ship where they can be worked over.

Vhat I claim is:

l. A fiume construction, comprising a fiume, a flexible suspension means connected to said flume, and supports for said suspension means.

2. A flume construction, -comprising a fiume having sides, a iexible suspension means connected to said sides, and means to adjustably support said fiexible suspension means. Y

3. A fiume construction, comprising a flume formed of concrete, a flexible cable supporting said flume, adjustable connections secured4 to said cable, and means to support said adjustable connections.

4. A fiume construction, comprising a metallic webbing, a plurality of flexible cables connected to said webbing, supporting connections secured to said cables, supports for said supporting connections, and

a cementitious material secured tosad Web- Y bing and inclosing the same.

5. A flume construction, comprising a metallic netting, a pair of flexible cables, means to connect saidV netting to said cables, supporting rods secured to said cables, supports for said supporting rods, and a cementitious material secured to said netting and cables and inclosing the same.

6. A Hume construction, comprising a continuous trough-like structure, a pair of suspension cables connected thereto and adapted to support said trough-like structure above the surface of the ground, and supportsfor said cables. l

In Witnessthat I claim the foregoing I have hereunto subscribed my name this 28th day of January, 1913.

CHARLES V. CRAIG.
