FIG.4
INVENTOR LEO A. EMANUELSON ATTORNEYS p 2,997,150 1C6 PatenteclAugl'ZZ, 1961 2,997,150 GRAIN SPUUT Leo A. Emanuelson, 6201 4th Ave. 5., Minneapolis 23, Minn.
Filed Apr. 13, 1959, Ser. No. 805,832 9 Claims. (Cl. 193-25) The herein disclosed invention relates to flexible grain spouts and has for an object to provide. a flexible grain spout consisting of telescoping sections connected together by chains and in which the wear may be distributed throughout the entire circumferential area of the sections.
Another object. of the invention resides in providing a grain spout'in which the sections may be easily and quickly rotated relative to one another and relative to the supporting structure to prevent undue wear at certain portions of the sections.
A still further object of the invention resides in constructing each section with a tubular body tapered in form and in providing the upper and larger ends of the body with an outwardly extending rim having an outwardly extending flange and a downwardly extending skirt forming a downwardly facing annular recess and inproviding a number of pairs of oppositely disposed notchesin the lower marginal portion of the skirt open from beneath.
Another object of the invention resides in providing a ring adapted to encircle the body and to enter said recess from beneath and to further provide pins extending outwardly from said ring and adapted to be received in said notches, said rings being connected together by chains adapted to support the sections for articulation, said sections being circumferentially adjustable relative to the rings to bring the pins into engagement with diiferent notches in the skirts of the rims.
' Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/or described.
In the drawings:
FIG. 1 is an elevational view of a flexible grain spout illustrating an embodiment of the invention.
FIG. 2 is a plan sectional view taken on line 2-2 of FIG. 1.
FIG. 3 is a perspective view of one of the supporting rings of the invention.
FIG. 4 is a longitudinal sectional detail view taken on line 44 of FIG. 2 and drawn to a greater scale.
The invention consists of a number of sections 10, 11, 12, 13, etc, usually about twelve sections connected tgether. Each of the sections is identical in construction and only the section which is shown in detail in FIGS. 2 and 4 will be described. This section consists of a tubular body '14 constructed of sheet metal and which is tapered, being of greatest diameter at its upper end and of least diameter at its lower end 16. The upper end of the body portion 14 is formed with a rim having an outwardly extending flange 16 and a skirt 17 depending therefrom and spaced from the body proper. This construction provides an annular space 18 between said and body 14 closed at the upper end through the flange 16. The skirt 17 is formed with an even number divisible by four of equally spaced notches 19 along its lower exposed edge 29.
Operating in conjunction with the body 14 is an annular ring 21 shown in detail in FIG. 3. This ring is of such dimension as to freely fit within the space 18 of the body 14 as shown in FIG. 4. The said ring has four pins 22 projecting outwardly therefrom and which are adapted to be disposed in any of the notches 19.
For connecting the sections together, a number of chains 23 are provided which have links of sufficient size to receive the pins 22. These links fit over the pins and cotter keys 24 extending through the outer ends of said pins hold the links attached to the same. By means of this construction, the various sections may articulate to cause the spout to flex and move to various positions to deliver the grain to the desired locality.
Theuppcr section 12 of the spout is attached to a connecting fitting 25 which forms part of the regular equipment of the elevator in which the spout is used. This fitting has at its lower end a neck 26 which extends into the spout 12. The same also has issuing outwardly from it lugs 27 and to which the upper ends of the chains 23 are attached 7 The device is used in the customary manner. However, at frequent intervals the tubular bodies 14 of the sections are raised until the notches 29 clear the pins 22. The bodies can then be rotated so that the pins will be received in other notches. 'Ihus the wear on the sections can be sembled and all of the corresponding parts being identical in construction, spare parts can be maintained on hand and the spout continuously kept in operating order. The parts are easily assembled and the adjustment to redu wear easily and quickly made.
Changes in the specific form of the invention, as herein described, may be made within the scope of what is claimed without departing from the spirit of the invention.
