FLUME.

Patented May 22, 1917.

Application filed June 13, 1911. serial No. 632,970.

T0 at whom it may concern .Be it known that I, LEROY R. HINMAN, a citizen of the United States, and a resident of Denver, in the county of Denver and State of Colorado, have invented a new and Improved Flume, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in fiumes for carrying water, logs, ore or other material from point to point.

An object of this invention is to provide a fluine constructed of sheet metal, without the use of rivets or solder at the joints, and which will be still water-tight and without projections, so that the material or articles passing through the fiume will not catch on the sides thereof.

A further object of this invention is to provide means for joining the sections of the fiume together, which will be simple in construction, inexpensive to manufacture, and which can be readily set up and taken down for removal or repair.

These and further objects, together with the construction and combination of parts, will be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a fragmentary perspective view;

Fig. 2 is a vertical transverse section,

showing the'flume empty and without buffer extensions on the hangers;

Fig. 3 is an enlarged detail showing the connection of the supporting members with the hangers;

Fig. 4: is a detail section showing the connection between two adj acent sections of the flume, with the means for securing the sections together; i

Fig. 5 is a fragmentary perspective View of one of the supporting members of the fiume broper;

Fig. 6 shows amodified form of supporting means; and

Fig. 7 shows the device with buifers therein, whereby the same can be used to float logs or ties without damaging the fiume proper.

Referring more particularly to the separate parts of this invention as embodied in the form shown in the drawings, 1 indicates suitable upright standards, on which are mounted longitudinally-extending beams 2. These beams may be of wood, as shown in Figs. 1 to 3 and 7, or may be in the form of I-beams, as shown in Fig. 6. In either case, they are used to-support hangers 3, arranged at suitable spaced intervals, which hangers overlie the tops of the beams, and are bent to engage the sides of the beams, so as to secure them in position. The hangers are arranged in pairs to engage the beams 2, which are arranged in parallel reaches, so as to support the flume proper 41 between them.

Each of the hangers is provided with an opening 5, through which extends, in each pair of opposite hangers, the ends of supporting bars 6, which are shown to be somewhat U-shaped in form, to correspond with thetransverse U-shaped section of the flume. The supporting bars 6 are of rather peculiar form, as will be seen by'reference to Fig. 4, in that they are provided with an intermediate cylindrical body portion 7, which is in the form of a curved rod, from which extends on opposite sides and in the same general direction, flanges 8 and 9, these flanges being spaced apart from each other to form a channel. It will be noted that the body portion 7projects into this channel to form an arcuate hump indicated at 10, which is for a purpose to be described.

The channel between the flanges 8 and 9 is adapted to receive beads 11 and 12, formed on the ends of two juxtaposed sections 13 and let of the flame. These beads are formed by bending the sheet metal of the Home in a channel form, with the chan' nel or bead 11 larger than the channel or bead 12, so as to encircle the same. That is to say, the channel 12 fits into the channel 11, so that no portion of it will extend beyond the inner surface of the sections 13 and 14, and thus no portion will extend into the fluine.

It will be seen that the rod 7 contacts with the outer channel orbead 11 at three points, indicated at 15, 16 and 17, which points,'however, are coextensive with the entire length of the rod, and thus form lines of contact which form a more secure support than would otherwise be obtainable.

For the purpose of securing the ends of the sections together in connection with the and which fits into the channel 12 formed in the overlapping end of the section 14:. This cleat 18 has a trapezoidal cross-section corresponding to the cross-sections of the channels 11 and 12 so that when it is forced into the channe1'12, it will tend to wedge the sides of the channels 12 and 11 together.

In order to force the cleat 18 into the channel 12, and thus secure the juxtaposed sections of the flume together, the hangers 3 are each provided with an inwardly-projecting extension 19, which is inclined at an angle to the horizontal portion of the hanger, so that it will tend to wedge the cleat 18 toward the bar 6 when the latter is drawn up, on each of the hangers, by means of nuts 20, which engage a screwthreaded portion 21 on the ends of the bar, the flanges 8 and 9 being cut away for this purpose.

r In case it is desired to use the flume for floating logs or ties and conveying them from point to point, it may be necessary toprovide suitable buffers, to prevent the ends of the logs, especially in going around curves, from striking the sides of the flume. In such an event, the extensions 19 may be projected along the side of the flume for a greater length, as indicated in Fig. 7 and provided with suitable buffing means, which in this instance .is shown in the form of running boards 22, extending along the sides of the flume for a sufficient depth, corresponding to the position which the floating logs would occupy in the flume.

It will thus be seen that there is provided a simple and efficient flume constructed of a series of U-shaped sheet-metal sections overlapping each other, with the ends provided with interlocking channels forced to gether in a detachable manner by U-shaped bars and cleats,which in turn are urged and clamped toward each other by their con nection with hangers supporting the flume as a whole.

While I have shown several embodiments of my invention, I do not wish to be limited to the specific details thereof, but desire to be protected in various changes, alterations and modifications which may come within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a plurality of hangers, of bars suspended from said hangers, a' flume supported by said bars, said flume comprising a plurality of sheetmetal sections, the ends of said sections being provided with transversely-extending channels, the channel at the end of one section nesting in the channel at the end of the next adjacent section, said bars being thickened throughout their length, and having flanges extending from the sides thereof in spaced relation from each other so as to form channels, one of said channels in each grip the ends of the sections between them. 7

2. The combination with a plurality of hangers, of bars suspended from said hangers, a flume supported by said bars, said flume comprising a plurality of sheet-metal sections, the ends of said sections being provided with transversely-extending channels, the channel at the end of one section nesting in the channel at the end of the next adjacent section, said bars being enlarged throughout their length, so as to have a cylindrical cross section, and having fiattened flanges extending from the cylindrical portion of the bars in spaced relation from each other so as to form a channel between them, one of said channels in each of said sections extending into the channels in said bars, said last-mentioned channel in said section contacting with said bar in three lines, and being spaced apart therefrom at other points, and a cleat extending into the other channel of each of said sections, so that a bar and a cleat will be located on opposite sides of each juncturebetwe'en two sections, so as to grip the ends of the sections between them.

3. A supporting bar, comprising acurved cylindrical bar having on opposite sides parallel flanges forming a channel into which projects a portion of the bar to form a hump in the bottom of the channel. 7

4. A supporting bar, comprising a curved bar provided on opposite sides with parallel flanges forming a channel having a hump in its bottom, the flanges terminating short of the ends of the bar and the said ends be LEROY RACE HINMAN.
