Dec. 5, 1961 A. P. OLSEN GRAIN DISPENSING SPOUT Filed Sept. 21, 1959 M2 Q K {Y Him nvenr or' A/V/I? Olsen United States Patent 3,011,612 GRAIN DISPENSING SPOUT Alvin Peter Olsen, Box 249, Sylvan Lake, Alberta, Canada Filed Sept. 21, 1959, Ser. No. 841,175 2 Claims. (Cl. 19322) My invention relates to new and useful improvements in grain dispensing spouts.

These improvements are applicable to the type of grain dispensing spout which consists of a plurality of tapered cylindrical sections loosely connected together with the narrow end of one section nesting within the wider end of an adjacent section. Conventionally, these sections are connected together by means of rings either welded to the sections adjacent the wider ends thereof, or, alternatively having outwardly flanged upper edges which nest Within rings surrounding the sections. A chain or similar flexible means then connects the rings together and supports the plurality of sections in the conventional way.

These suffer from two principal disadvantages, firstly, it is diflicult to replace sections if wear occurs, if the rings are welded thereto and secondly, it is normal for the grain spout to be used in a fixed position so that when wear occurs on the walls of the sections due to the action of grain passing thereby, the section has to be discarded.

l have overcome both of these disadvantages by providing a tapered ring which wedges around the wall of the section adjacent the upper end thereof and which makes assembly and disassembly extremely easy. Furthermore, by scalloping the upper edge of the device, I can obtain a greater angle of bend and also individual sections can be rotated to any one of five positions as wear occurs thus evening out the wear around the entire inner surface of the sections thus saving in replacement.

The principal object and essence of my invention is therefore to provide a flexible grain dispensing spout which can be angulated in any direction or, alternatively, in which the individual sections can be rotated as wear occurs.

Another object of my invention is to provide a device of the character herewithin described which simplifies the construction of the sections and simplifies the attachment of the sections to their retaining rings.

A yet further object of my invention is to provide a device of the character herewithin described which is extremely sirnple in construction, economical in manufacture, and otherwise well suited for the purpose for which it is designed.

With the foregoing objects in view, and such other objects and advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, my invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:

FIGURE 1 is a side elevation of a plurality of sections incorporating my invention.

FIGURE 2 is a top plan view of one of the rings per se.

FIGURE 3 is a side elevation of one of the sections with my ring installed.

FIGURE 4 is a fragmentary enlarged partially sectioned view of one of the rings.

FIGURE 5 shows the upper portion of a single plate developed in a straight line which forms one of my sections.

In the drawings like characters of reference indicate corresponding parts in the difierent figures.

Proceeding therefore to describe my invention in detail, reference should be made to the accompanying drawings in which the grain dispensing spout collectively designated It) consists of a plurality of sections 11 each section of which is of a tapered cylindrical construction having a relatively narrow lower end 12 and a relatively wide upper end 13, it being understood that the lower end 12 of one adjacent section nests freely within the upper end 13 of the next succeeding section.

The sections are formed from a rectangular sheet of metal, the upper edge 14 of which is scalloped as illustrated in FIGURE 5 to provide a plurality of depressions 15 as clearly shown. The sheet is then formed into the tapered cylinder and the edges 16 of the sheet are butt welded in the conventional manner.

The rings collectively designed 17 are formed from strap material and formed with the inner surfaces 18 tapered as clearly shown in FIGURE 4, this taper corresponding substantially to the taper of the section 11 and having a diameter slightly less than the diameter of the upper end 13 of the section. Lugs 19 are welded to the outer surface 2% of the strap and carry bolt 21 by which the sections may be articulately connected together by means of a chain 22, selected links of which are engaged by the bolt 21.

The assembly then merely consists of dropping the section through the ring until the ring binds against the wall of the upper end 13 of the section and then passing the bolt 21 through the links of the chain to connect the sections together.

As wear occurs on the inner walls of the sections due to the action of the grain passing thereby, the sections can be rotated so that difierent depressions 15 are engaged by the outer surface area 23 of the next succeeding section thus permitting the sections to be rotated so that Wear is distributed evenly around the entire surface.

Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.

What I claim as my invention is:

1. In a flexible grain distributing spout including a plurality of tapered cylindrical sections articulately connected together by virtue of the ends of one adjacent section loosely nesting Within the end of the next adjacent section; means to connect said sections together comprising a ring; the inner surface of said ring being tapered to complement the taper of the associated section, said ring engaging the wall of said section adjacent the wider end thereof, and maintaining position by wedging action, flexible means connecting adjacent rings together and means whereby said sections may be angulated one with relation to the other.

2. The device according to claim 1 in which said means whereby said sections may be angulated one with respect to the other includes an upper scalloped edge for each of said sections.
