."Assorvrnvc.` AND sizING APPARATUS.

`Speciatgill of' Letters Patent. .y .l Patented Aug. 31, 1909.

Application led July 3, 1907.` I' SerialvNo. 382,063.

To all whomV it may concern: j Be it known that I, EDWIN W. J oriNsoN,

citizen of the United States of Americane-V siding at East Palatka,in the county of Putnam and State of Florida, have invented certain new and useful Improvements in Assorting and Sizing Apparatus, ofwhich the following is a specification, reference being had therein to the'acco'mpanying drawing. Y

The object of my invention is to produce an apparatus for automatically assorting articles and things according to their sizes;

for example, grape fruit, oranges, apples, and other things, whether natural or artificial.

In the drawings illustrating the principle of my invention, and the best mode nowl of the main frame being higher than .its

other end; 1, 1 are a pair of endpostsat the higher end of the main frame, and 1a, laare a pair of end posts atthe lower-endlofthe apparatus. VEnd posts 1, 1`(Fig. 3) are cong nected by across-bar y15 below the `upper ends of the posts 1. On `the upper edge of cross-bar 15 there is mounted Ia slide-stop 16 having a lengthwise slot 17 formed-in it and provided with an upwardly extending lug 18 at one of its ends. A set-screw` 19, through cross-bar 15, passes through slot 17, and is provided with a nut 20 whereby the adjustable stop 16 may be mounted in any desired position on the upper edge of crossbar 15. A diagonal guide-support 21 reaches from one of the legs 1 to the crossbar 15, and a guide 6, hereinafter referred to, is supported on its under side on support 21, the lower edge ofthe guide 6 abutting against the projection y18 ofthe adjustable stop 16. The guide' is conveniently formed with a cleat 22 on its under surface, the `cleat directly resting on support 21; but this is a matter of immaterial detail, the point being to support the guide 6, the innerV surface of which is flat, in Va slanting position with reference Yto a vertical plane extending lengthwise of and through the main frame A. The posts l 'are'also connected, at their upper ends, by a cross-bar 23 (Fig. 3), on which the bearing 3 of the shaft of screwconveyer 2 ismounted. i

Posts la, 11l areshorter than the posts 1, which are respectively connected together by the lower, side cross-bars 241, each pair ofV posts being preferably connected at the opposite ends of frame A by cross-bars 25. Posts 1, land 1a, 1L are also preferably connected by the upper, side cross-bars 24a, 24a; and the shorter endl posts la, 1a are connected transversely by a cross-bar 26, provided on its upper surface with a sliding adjustable ,stop-16a, in all respects .the same in construction` and mode of operation as the adjustable stop 16 on the lcross-bar 15, which is higher than the cross-bar 26, the edge 7 of the guide 6 also resting against this adjustable stop. Hence, guide 6,' while slanting with referenceto said vertical plane, also slants downwardly, from its connection with posts 1 `and the cross-barV 15 to its connection with the posts 1a and their cross-bar 26. Posts 1a. are connected` by a cross-bar 27, which is lower than the cross-bar 23 and which supports the bearing-3at for the lower end of the shaft of screw-'conveyer 2. This lower end of said shaft is preferably provided with a handle 4, while the higher end of the apparatus is provided with a suitable hopper 8 for receving fruit or other objects to be assorted `accordmg to slze.

The guide 6 and the screw-conveyer 2 are in line one with another, and the convolutionsv 5 of, ,thev screw-conveyer have their edges and alternating spaces opposed to the inner side of the guide 6; and the articles to be assorted are conveyed from the hopper,

.which is inclined from end to end so as to the opposed surfaces of the guide and screwconveyer at one end thereof than at the other,

so that fruit or other objects of varying size may drop through the spaces 9, between the convolutions of the screw-conveyer and the upper edge of the guide, into bins or chutes 11, below the lower edge of the guide 65 the upper edge of which is suliioiently ele vated to be opposed to the SereW-CQnVeyer, so that the two form a sort of open-bottomed trough, one side of Whiohis formed by the adjustable guide 6 and the'other side of( which is formed by the screw-.conveyer.

in Fig. 3,' vthe adjustable connection ofthe Yhigher end of guide 6 with the adjustable lable sto j 16*1 Vbein shown in -FiOzY 5.

A 7 Y C b What I Claim is;

In fruitassortlng andvslzlng apparatus,

v; Vthe combination of an inclined screw-con Veyer with an adjustable guide extendmg 'guide extending under the screw-conveyer along the length thereof and `being at a distance therefrom to form an under-discharge;

and adjustable stops by which the lower edge of the guide is j, adjustably maintained 1n working posit-ion.

In testimony whereof I atlix my signature in presence of two Witnesses.
