nussnnr. E. ABNARD, or DENVER, cononano, ASSIGNOR TO THE R. HARDESTY MANU ACTURING AW-ff coMrANY, or DENVER, COLORADO, A CORPORATION or COLO- FLUME CONSTRUCTION.

Application filed March 1, 1927. Serial No. 171,785.

My invention relates to improvements in sectionalnsheet metal flumes of the type transversely disposed cross beams.

shown and described in U. S. Patent No. 1,584,290, issued May 11, 1926, to Rudd Hardesty. I i I In the flume Construction disclosed in the patent, abutment sleeves and wedging shoes cooperate with suspension rods and bevel bars to secure the sections of whichthe flume is omposedin water-tight contact with each other and to suspend the structure from It has been demonstrated in practical use that the shoes made separate from the sleeves are, under certain conditions, disadvantageous particularly with respect to the assemblage of the parts when the flume is being constructed or repaired, and it is an object of the present invention to eliminate the shoes from the fiuine structure by the provision of an abutment sleeve of novel construction which in addition to its own function, performs every function of the shoe with equal if not better effect and which greatly facilitates the work of assembling the parts of the flume structure in their proper relative positions.

An embodiment of the invention has been illustrated in the accompanying drawings in which like parts are similarly designated throughout the several views and in which Figure 1 represents a fragmentary side elevation of a flume constructed in accordance with my invention,

Figure 2, a transverse section along the line 22 Figure 1, drawn to an enlarged scale,

Figure 3, a further enlarged section of one of the improved distance sleeves together with the other parts of the flume suspending means, with which it is directly associated,

Figure 4, asection taken on the line 44, Figure 3,

Figures 5 and 6, views similar to Figure 8, showing modifications in the construction of the abutment sleeve, and

Figure 7, an enlargedsection along the line 7-7, Figure 2.

The flume structure as shown in the drawings comprises a series of longitudinally alined semi-cylindrical sheet metal sections 5 which overlap one another at their adjoining ends. The lapping ends of the sections are beaded as indicated at 6 in Figure 7, and they are engaged at opposite sides by a suspension rod 7 and a so-called bevel bar 8 both curved in conformity with the flume. it

The rod 7 which is disposed exteriorly of the flume, has its ends projecting through vertical bores in one of a. number of cross beams 9 from which the flume is suspended,

the bores being bushcd with the metal abut-I ment sleeves 10 which are the principal subject of the present invention.

The sleeves as shown in Figures 2 and 3,

sponding end of the respective bevel bar with a wedging effect. e a

The upper ends of the rods are screwthreadied for the application of nuts 12 which in practice bear upon washers 13 placed in engagement with the upper ends of the sleeves. iVhen the nuts are screwed down upon the washers the rod is drawn tightly around the lapping ends of the flume sections while atthe sametime the bevel bar is forced inwardly by the wedging action of the beveled projections at the lower ends of the sleeves.

The rods indent the beads of the flume sections as illustrated in Figure 7 and the several parts of the suspension element, thus cooperate to produce a water-tight tween the sections.

The abutment sleeve illustrated in Figure 3 may be made of wrought or cast Iron, while that shown in Figure 5 can be made of fiat material die-cut and formed with an open side seam, or of tubing cut to provide the slanting lip 10 which as in the first de-. scribed form of the invention, is the part by which the bevel isforced to engagement with the inner surface of the flume. v

In the form shown in Figure 6, the sleeve has in addition to the projection 10 and in opposed relation to the same, a downwardly projecting tongue 10 which by enga ement with the suspension rod prevents the rod from being canted when the nuts are screwed home upon the washers.

The sleeves made as shown and hereinahove described provide a dependable, strong and rigid means for the suspension of the flume and the water-tight connection of the sections of which it is composed, they permit of self-adjustment of the flulne struc- 'ture in case of shrinkage or decomposition of the wooden cross beams Without readjustmentof thenuts and they furthermore provides space betWen the fiunie and the cross abutntientsleeve for flurne structures comprise ing a tubular body :lnelnber, and at an end thereof, anintegral lateral PlOJQCUOIl having a Wedging surface slanting relative to the axis of the body member.

2, As a new article of manufacture, an abutment sleeve for flume structures comprising a tubularbody member and at an end thereof, an integral lateral project-ion having 'a We'dging suit-face slanting relative to the axis of the body member, and opposite to said projection, an integral downwardly ranging tongue.

3. In a flume structure, the combination with. a tiume and a cross beam having openings for the suspension thereof, of a rod and a bevel bar engaging the flulne at opposite sides thereof, the rod projecting throughthe openings of the beam, bushings in the openings, having integral projections bearing on.

the ends of the bevel bar, and nuts on the endsof the rods, bearing on the bushings.

4c. In a. fiume structure, the combination with a fiume and a cross beam having openings, having integral projections bearing on the ends of the bevel bar, and nuts on the 1 ends of the rods, washersengaging the upper ends of the bushings, and nuts bearing on the Washers.

5.111 a .fiume structure, the combination with a flunie and a cross beam having openings for thesuspension thereof, of a rod. and a bevel bar engaging the flume atyopposite sides thereof,the rod projecting through the openings of the beam, bushings in the openings, having integral projections bearingon the ends of the bevel bar, and havingopposite to said projections, integral downwardly. ranging tongues bearing on the rod, and nuts engaging ontheends of the bar, and nuts on the ends of the rods bearing on the bushings. In testimony whereof I have afiixed my signature.
