This invention relates to improvements in grain handling apparatus and particularly I'elatesto a device for distributing different grades of grain in a manner to prevent mix- Q ing thereof.

n devices of this kind there are generally two elevator legs used, and there is generally some arrangement whereby both legs can be connected either to deliver grain into one I0 bin or car at the same time, or to simulta these connections are generally either swingv able on a vertical axis, or are arranged to be adjusted in a vertical plane in a direction toward and away from the legs. This is obu jectionable because the spouts must be lifted bodily in order to register their delivery ends with the proper lead or passage to a particular bin or car. Moreover after bodily lifting the spout it is necessary to lower it, while under bodily strain, and obtain registration between its delivery end and the passage. Under these conditions it is difficult to obtain registration and moreover, the spout adjusting and registration movements cannot be controlled from a remote point, as is desired, without an expensive construction. Even with expensive constructions registration is diicult and uncertain. Therefore important Objects are to provide a simple construction, by which registration can be quickly and unfailingly made, and controlled from a remote .j point.

Other objects are to provide a form of adjustable leg which has a pendular motion, and 4which therefore is easily adjusted; to provide a construction including two pendular legs, swingable on a common axis, and

each ,connected with a separate leg; to providev Features of the invention also include the' details of construction. Objects, advantages and features of the invention will ap ear from the description of the drawings orming a part of thisV ape plication, and in said drawingsf Figure 1 is a vertical section through a granary structure showing the invention api plied thereto, the mechanism being shown v1n face View;

Figure 2 is a detail face view showing one of the adjustable spouts in section, the secl' tion being taken on line 22 of Figure 4,

Figure 4t is a section 'substantially "on line 4-4 of Fig. 1; and

Figure 5 is a detail perspective of the pendular s out.

First re erring to Figure 1; The elevator legs are respectively designated 1 and Q-and may be of any preferred construction.v Eachv leg is provided with elevating buckets mounted on chains 4, see Figure 4. The grain is delivered bythe buckets into respective` chutes 5, which chutes connect with the 'ad-v justable spouts of the present invention. construction by means of which chutes 5 corne.` municate with the spouts and they pendular arrangement of the adjustable spouts,

all features of the invention. Each spout comprises an elongated portion 8, and a por-v tion 9 divergent toward a structure 12 and merging into or' connected by a band10`whi'c`h surrounds, movably embraces, and rides upon'` the hollow structure 12. Spacer rings 13are employed to separate the elements 9 and to secure them against movement upon the struc-- ture 12 in a direction axial thereto. this means the spouts are mounted to have pendular motion, about the drum 12' asfan axis, and it will be seen by an inspection of Figure 3 that inasmuch as the arc of swinging movement is comparativly small, (about sixty degrees) little force is required to swing" the spout to position it for registration Vwi the leads or passages to the bins. Thereforer this structure lends itself to remote control, in that little force is required to adjust it. n, Referring to Figures 1 and 3,v a structure is provided having an arcuate channel l5, the bottom of which is curved on a radius having the axis of the hollow cylinder 12 as a center. Leading from the bottom of this guide-channel are two rows of spout-receiving openings or passages generally indicated at 20, a passage for each bin or car. .Y Referring to Figure l, the bins, only some of which have been shown, are generally indicated at 2l. Leading from each passage is a spout 23 leading to a respective bin. 0f course there is no intention to be limited to the number of passages 20 inasmuch as they may be increased and decreased according to the desired size or capacity of the installation.

Referring to Figure 4,the width of channel l5 is such as to receive and form a guide for the lower ends of two opposingly related spouts 7 to prevent movement in a direction of the axisof the cylinder 12. Thus the sides of the channel l5 prevent movement of each spout in one direction, while the partition element 26 prevents movement of each spout in an opposite direction. This is a feature of the invention because it prevents such movements of the elements 7 as would cause a deposit of grain otherwise than in one of the passages 20. y Y

, Referring now to Figures 3 and 4, the lower ends of theV portions 8 lie just above and therefore clear the top ofthe partitions 27 which define the passages 20, or just clear of the bottom of the guide channel l5. The tops of thesepartitions lie on a curved line having the axis of the cylinder as a center.

Inrorder that each spout portion8 can be properly connected with a particular passage 20, so that all the grain passing through the spout will be caused to enter a particular passage, the lower end of each spout portion 8 is provided with a telescopically arranged spout extension 30. rlhese extensions are shown in raised position in Figure 4, and in lowered position in Figure 3. As soon as the element 8 is swung into alignment with one of the passages 20, the element 30 is projected into the passage as shown in Figure 3, whereby the element 8 is thereafter held against movement, and whereby the grain can only pass into that particular passage 2O into which the element 30 extends.

`Thedistributing spouts 23, although shown herein as rigid, may be and often are, adjustable, and for this and other reasons the attendant on the bin floor indicated at 35, see Figure l, desires to have the means for controlling the spout 7 operable from this point. 'VF or this purpose the band lO or equivalent element swingingly securing the pendular spout, has attached thereto two cables, one attached as at 40 and the other attached as at 50, and extending partly around the band in opposite directions. The cable 5l attached at one end at 50, passes over a pulley 5.2, then rearwardly and downwardly over a pulley 53, thence to a control wheel 54 around the control wheel then again upwardly over an idler wheel 56 thence to pulley 57, forwardly to pulley 58 and around the drum in an opposite direction to be connected at 40. The wheel 54 is a kind of dial and is provided with numbers corresponding in number to that of the passages 20. When the wheel 54 is operated the element 8 will be correspondingly moved to alignment with one of the passages 20. Inasmuch as the mechanism for moving each leg is substantially identical, only one has been described. Moreover there isno intention to be limited to a two leg or two spout construction.

Means is also provided operable from the binfloor to raise and lower each spout extension 30, and means is also provided whereby a signal is given as soon as the spout extension is properly positioned in one of the passages 20. Referring to Figures 3 and 4 the signal means, in this instance, comprises a gong 60 with which is associated a clapper 6l pivoted at 62 upon the portion 8 of the spout. A clapper retraction spring is shown at 68. The stop 59 carried by the control cable 64 engages the clapper, after element 80 has entered a passage 20, see Figure 3, and causes it to ring the gong. p

The element 64 is Connected as at 65 to the element 86, and passes upwardly over a pulley 66, thence over a pulley 67 through the drum (see Figure 4) to a pulley 68, and downwardly to the bin floor ending in hand grip 69, see Figure 2. f. g
