GRAIN-SPOUT FOR PORTABLE ELEVATORS.

Specification of Letters Patent. Patenfigd Egg, 14 time,

Application filed J uly 11, 1908. Serial No. 443,154.

To all whom it may concern.

Be it known that we, GEORGE W. BAIER and CHRISTIAN D. Bimiu, citlzens of the United States, residing at Cissna Park, in

the county of Iroquois and State of Illinois, have invented a new and useful Improvement in Grain-spouts for Portable Elevators, of which the following is a specification.

Our invention relates to certain new-and useful improvements in grainspouts for portable elevators, and is fully described and explained in the specification and shown in the accompanying drawing, in which:

Figure 1 is a side elevation of our-improved device; Fig. 2 is a top plan thereof; and Fig. 3- is a longitudinal section taken at the line 3 on Fig.

Referring to the drawing: adapted for attachment to the discharge end of a grain-conveying elevator and the same terminates at its lower end in a cylindrical sleeve a having at its extreme lower edge a bead a This hopper isbound preferably by a band at its upper edge for the purpose of protecting and strengthening the hopper and for preventing undue wear. A- cylindrical collar B having an inturned bead b at its upper edge surrounds the sleeve a and is limited in its downward movement with respect thereto by engagement of the beads b and a while being free to rotate with respect thereto;

Three conical sections C, C and O are provided as illustrated and below these conical sections is a series of cylindrical sections D, D and D each telescopically IHOHlliQClilPOll the one above it and each of the cylindrical sections being provided with a reinforcing or trengthening ring (1. Chains a, secured to each of the conical sections C, C and C by pins 0 and attached at their upper ends to the cylindrical collar B and at the lower ends tothe upper cylindrical section D, serve to flexibly secure all of said sections together in suspended relation to the hopper. The cylindrical sections, which may be of any desired number though only three of such sections are shown in the drawing, are secured together by means of chains (Z which in practice are preferably arranged ninety degrees away A is a hopper from the correspondingchains c on the conical sections 0, C and C The chains IZ" are provided at intervals with rings adapted tobe engaged by snap-hooks 1/, which are attached to the rings (Z, for the purpose of holding the spout in a shortened condition. The purposeof such adjustment will be at once apparent, when it is considered that as the crib or bin lills up at the far end (to which the grain is first delivered) it is obviously desirable to contract the length of the spout for filling the central portion and afterward the remaining portion.

The degree of taper to the conical sections is so proportioned that the hopper can be turnedat substantially ninety degrees to the cylinder sections as illustrated in Figs. 1 and 3 of the drawing and the number of sections and the degree of taper therein illustrated are such as to produce the requisite degree of curvature without diiiiculty. Should it be desired, however, to vary the number of the sections to any extent, the degree of taper, will be correspondingly modified to permit the samedegree of bend. Some grain elevators are on the market in which the discharge endis not horizontal, but is inclin d at an angle, and in such cases it is possible to dispose the hopper in other than a horizontal position, and in such case it would be sufiicient if the conical sections were made with only suiiicient bend to permit the cylindrical sections to take a horizontal position. 7

It will be understood by those skilled in the art that the grai11-spout herein shown is of the type which is especially designed for the handling of ear-corn, although small grains may be equally well spouted by it, if desired, and in the operation thereof, the corn or grain falls, striking the curved surface of the interior of the spout at the conic'al sections, and being thereby deflected into a horizontal direction of movement, and acquires by its fall a considerable speed, so that it will move without the addition of further force through the entire length of the cylindrical sections, even though they be supported in a substantially horizontal position as illustrated. By this mode of operation, born can be dlstributed 1n a corncr'ib with the greatest ease even to the ends of a comparatively long crib, or grain may be equally well distributed into a bin if desired, and it is only necessary to direct the end of the spout to shift the stream as may be desired, the cylindrical -sections being self supporting in the same plane whensupported at the ends and the conical sections being so arranged as to permit the requisite amount of bend to bring the c lmdrical sections to a substantially horizontal plane, and

lines. This section is preferably made con- .ical'in form for convenience in handling I on the band of section B and to permit a greater degree of an movement, without an undue waste of material in the formation of the section, but

it may be of other forms if desired. This section 'is preferably reinforced and strengthened by bands-e secured externally of the section at its ends,.and is flexibly secured to the section D 'by means of chains e connected by snap-hooks c with the upper edge of the section D as illustrated, and for holding this section in adjusted position, the band 6 at its lower smaller end is provided with eyes or loops 6 to which a rope may be tied for this purpose. I The stream ofcorn or grain issuing from the spout can be turned to the right or left or up'or down to a limited extent suflicient to deflect the grain the desired amount, without the difliculty or inconvenience of shifting the entire end of the comparatively heavy spout.

. It will readily appear that the inner surface of the section E will become worn, when adjusted in position at an angle to, or out of-alinement with the cylindrical sections. This "wear is due to the friction of the corn or grain, in its passage therethrough, in being deflected in its course by'the angular adjustment of this section. This is especially the case when the section B is'raised at its outer end to give an upward shoot to the grain in its passage therefrom, and to prolong the life of this section, provision is made for its independent adjustment by turning it one-half way around, or through an arc of 180 degrees. To effect'this adjustment, thesnap-hooks which hold this section to the section D through the medium of the chains 0 are disengaged and after the proper adjustment, the snap-hooks are again engaged with the aliningv loops v WVear'will also take place in both the conical and cylindrical sections may be changed simultaneously by the swinging of the spout from side-to side .through a perpendicular plane.

we realize that considerable variation is possible in the details ;of construction of our improved device, without departing from the spirit of our invention, and we do not intend therefore, to i limit ourselves to the specific form herein shown and described.
