GRAIN snrnnnron.

Application led June 9, 1925, Serial No. 36,015, and in France .Tune 14, 1924.

The present invention relates to grain separators particularly utilizable for sorting one or several kinds of grains or seeds out of a mass of commingled grains or seeds, of the type described and illustrated in the co-pending application Ser. No. 19,104 and it has for its object to still furtherv improve this type of grain separator particularly with a view to materially enhancing its sorting capacity for a limited volume of the apparatus.

Briefly stated, the present improvements consist in arranging the frusto-conical ring members of which the annular separating elements are made up externally of their supporting cylinder with their inner edges fixed adjacent to said cylinder in juxtaposed relation and their outer free edges remote from lsaid Cylinder slightly spaced apart as to provide narrow passages .extending circumferentially. They further consist in providing` both the outer and inner faces of each of such ring members. with a large number of contiguous alveoli or sockets so sized, shaped and arranged as to pick up the proper grains or seeds from their commingled mass. They still further consist in providingpivoted scoops between the pairs of cooperating socketed ring members for receiving whatever grains or seeds are picked up by their inner alveoli or sockets and for suitably discharging them.

lith such features and such others as will incidentally appear in the following description, the present invention comprises the novel construction, combination and arrangement of parts that will now be described with reference to the accompanying drawing wherein Fig. l is a longitudinal sectional view of the improved grain separator according to the invention.

Like reference characters designate like parts throughout the several views.

The improved grain separator shown in @aan these figures comprises a substantially horizontal shaft l rotatively mounted in bearings 2 and 3 within a stationary prismatical or cylindrical drum-like casing 4, which shaft carries an outer driving pulley 5 and an internal cylinder 6. Upon the outer surface of this cylinder are fiXedly secured in any The ring members 7 are secured to the outer face of the cylinder G in any suitable way and preferably so as to be readily dismountable. They are formed along their inner edge, i. e. theV one which is positioned adjacent the cylinder 6 with slits l() for a purpose to be hereinafter set forth. Their outer free edges, i. e. those edges remote from the cylinder 6 are slightly spaced apart so .as to form narrow passages 32 eX- tending circumferentially, also for a purpose to be hereinafter described.V The outer and inner faces of each ring member 7 are formed with a large number of alveoli or sockets 11 (see Fig. 3) sized, shaped and arranged as described and illustrated in the copending application above referred to.

As already stated; this improved construction is vadapted for still further enhancing the separating capacity of the grain' separa- 'tor without correspondingly increasing its volume inasmuch as both the outer and inner faces of the ring members 7 are formed with contiguous separating alveoli 1l and thus efficiently partake of the grain separation. The commingled grains are fed by an inlet pipe l2 at one Xtremity of the outer drumlike casing 4 and lill the bottom part of said casing, wherein they are conveyed towards its opposite extremity by the rotation of the annular separating elements. The proper grains (wheat grains for instance) are t-hus picked up by the outer alveoli on the upwardly moving side of the said elements and dropped off or ejected at 13 on the opposite side whence they fall on an inclined board 14 and into one or more discharging hoppers l5. Moreover, as the commingled grains can penetrate through the passages 32 into the inner spaces between the outwardly converging ring members 7, they can also be picked up by the alveoli ll formed on the inner faces of such members whereby the separating eifect is largely i'ncreased. VVit-hin such inner spaces are provided gutters or scoops 323 the purpose of which is to receive the proper grains thus picked up by the inner alveoli at the moment when they drop oil therefrom due to the rotation of the ring members 7 and to discharge them at 34 (see Fig. 2) whence they can fall on the board lil and into the hoppers 15.

The gutters or scoops 83 have the shape of sharp isosceles triangles (see Fig. 4) for snugly occupying the whole of the inner space between the outwardly converging ring members 7. rl`hey are pivotally connected upon thin rods 35 suspended from a longitudinal channel bar 36 tixedly secured to the outer casing l and extending into the said inner spaces through the said' narrow spaces'vfQ between the outer edges of the ring members 7. In Fig. 5 is illustrat-ed by way of example a method of adjustably securing the rods 85 upon the channel bar 36 by means of a screw-threaded portion and of three nuts 88. lVhen it is desired to remove the gutters 33 from the inner spaces 72L between the outwardly converging ring members 7, all that is necessary is to bring them in alignment with their respective carrying rods'V 35 and to turn the latter to the extent of 900. The gutters are then brought edgewise with respect to the annular passages 32 the width of which is larger than their thickness whereby a movement of translation is sufficient to remove them.

As above described, the ring members are preferably formed adjacent the cylinder 6 with slits l0. lVithin the latter are thrust obliquely disposed blades 16 which are adapted to push onward the mass of grains from one groove or fluting tothe succeedingones. As the mass of grain travels towards the outlet extremity of the casing 4, itis being continually subjected to the action of the alveoli ll, and the grains to be separated from such mass are removed in increasing proportion, so that on delivery the mass contains only refuse grains. Y

ln accordance with the patent statut-es, the principles of construction and operation of the invention as well as a convenient embodiment of same have been described. lt will however be understood that the said invention is notlimited thereto .and that numerous modifications might be introduced without departing from'its scope and spiritas will now be emphasized in the appended claims. v

lNhat I claim and desire to secureY by Letters Patent is l. A grain separator of the type set forth comprising in combination an outer stationary elongated casing having a grain inlet at one extremity, sorted grains discharging hoppers on one side and non-sorted grains discharging means at its other extremity, a rotary supporting cylinder mounted upon a longitudinal driving shaft anda plurality of contiguous annular outwardly tapering separating elements lixed externally upon said cylinder so as to have a saw-tooth outline and each formed by a pair of symmetrically arranged frusto-conical ring members slightly spaced along their outer edges and formed both on their outer and inner faces with a large number of contiguous alveoli adapted for picking up and afterwards dropping ott and thus separating out the proper grains from a mass of commingled grains fed at the inlet extremity of the separator, filling the lower portion ofthe casing and thusv contacting with the said ring members in proportion as they rotate,

2. A grain separator ofthe type set forth comprising in combination an outer casing and a rotary cylinder mounted lengthwise therein and carrying a plurality of contiguous annular outwardly tapering separating elements fixed externally upon same and made up of fru'sto-conical ring members arrangedl in co-,operating pairs, each of which is constituted by a number of segments having sorting alveoli on both faces slightly spaced apart ,and formed adjacent said cylinder with slits, oblique blades being engaged into said slits for propelling the refuse grains towards their outlet situated at the extremity of said casing opposite to the inlet. j
