Thisiinvention relates to sorting machines and, more particularly, to a machine for sorting'leather sole blanks of the type now in common use, 7 As s well known to tion' of the hide from which the blank] is formed and the present p'racticeis to employ a gauge having'fan angular notch in which the edge of; the i bla'nlr' is inserted to deter rn'ine'thetliick'n'ess. Obviously, blanks eni ployle'dfupon" a"pair of sh'oes'must'be of the same thicki ies's and this' sorting is further necessaryfdue to thefac't that blanks of difi'er-i ent thicknesses naturally have dilferent- Weigllts and "accordingly mustbe sold for' di'fi'erent prices; An important object of v the'present invention, is the provision of a structjurefor automatically sorting such I H m, I blanks and deliver ng themto recelvers.

invention is the provision! of a thickness c gaugehaving a longitudinally-extending slot varying'in' Width from end to end, having associatedtherew'ltha 'means for causing the blanks to travel therealong; the, blank pass ing through the gauge when it arrives at -a point such that its size permitsit to do so.

y Afur'tlier obj ectojf the :inventionis the provision of a construction such; that the blank;

once it begins its'passag e. through" the thickness gauge,-i s rapidly drawn therethrough' so-that'there is no danger 'ofitfs being' shiftedby the conveyingi'mechan-isin ,--to 'a point Where it willenter a receiver other than thatin', which it belongs.- M

A l stilll-further object of the invention is 1 to provideyin apparatus of this char acten a 1 gauge constructioneliminating, in so far p'ossible,=the resi'staiice to thepassage "of the is movedithereal'ongzl These and 'other' objects; the" n r c io hbw fi 'j ll iiac p' p y drawings wlie1e'in', 'for the "purp i of illusl elnbodi tration;' have; shown "a preferri Of my; mr ntwn ndi W 1??? i Fig. 1 1s a front ele'vatlon'ofa sorting ma- H those familiar with thevv art, the thicknessofsole leather in such blanks varies considerably, depending. upon the por 1929.

Fig; 13 is 'a' section online"3 8 of Fig: 1; and v I V Fig.= 4 is a section onglineoff-Fig; 1.- .JReferring now nore' particularly to the drawings, numerals 10 and 11 designate spaced supporting-standards; J ournaled in-"- vthe standards 10 and 11 adjacent theupper' ends thereof are upperand lower'pairs of

rollers

12 and 13. Rollers 12 are constructed and arrangedto provide therebetween a gap" 14 which increases in width from 'end'to end of the rollers. This gap may be produced either bysmounting the rollers with their axes diverging or by tapering the rollers longi- I titudi'nally; Rollers :13 may have their'axesparallel and may afford therebetween a'gap 15 which is uniform in Width; although it is:

preferrecL-as in the case of the rollers l2, that A"furtherand 'more specific object of the it increase in width; The gap 15, "however','

willbe of less widthiat any given point thanthegap 1 1 at the same point.

,Arranged above'the

rollers

12 and 13 and supported from standards 10- and; 1 1 are,- vertically s'paced pairs of guides 16 and .175;

these guides aligning with the gapbetween the roHersin'such fashion thata blank 18 disposed}therebetween is. guided into the spacebetwen rollers 12" and is aligned with? theispacefbetween rollers 13. Theguides 16 and 17 J are connected at spaced intervals 7 by'vertic'ally-extending standards 19 which;

at one'side' oftheguiding structure thus produced, maybe ofli'se't outwardly; as at 20,t0 provide seatsfora'guide-rail 21' in-the form; Oran angle. ironi The horizontal-flange 22" of this iron supports one run" of a conveyor T 9D aboutsprocket'wheels 24' and 24 'mounted in f a r t" ll- 't d'n b r' db thefi 1 blank-result1ngfroni frl 'c't 'onpas the blank 1 lea y ex en 1 g ea lugs Carne y standards 10 and 11; i r The sprocket wheel 24 1 is secured' toa' shaft uponcthe lower en'd'of which; ismjounted a bevelled gear '25. s

Associated; with: the standard 10 is a drivingamotor 26 which; through suitable gearing pperatesm nlaindriving gear 27. Thedrlv ng gear; 27 ;1 s.-l0eated-w1th 1n ,a gearcase:

28 c'arried bythe upper end of standard-1O L adjacent faces ofrollers12are moving upwardly, they will tend to elevatethe blanks.

and meshes with a gear 29 secured to the end of one of the rollers 12. The other of the rollers 12 has secured thereto a gear 30 mesh- 7 ing with gear 29 and with a gear 31 upon the end of the roller 13' lying therebelow. Rollers 13 inwardly of'standard 10 are provided with meshing gears 32. It will be obvious that on the rotation'of gear 27, rollers 12.

will rotate in opposite directionand rollers 13 will'rotate in opposite directions, and the rotation of corresponding rollers 12-and 13 will be opposed; The direction of rotation is such'that adjacent faces of rollers 12 are,

moved upwardly, while those of rollers 13 5 are moved downwardly. r

The gear 29 also meshes with a gear 33 secured to one end of a shaft 34: extending through the standard and having at its inner end a bevelled gear 35 meshing with the bevelled gear 25' ofthe conveying'sprocket shaft. The conveyor chain is provided with spaced projecting flight elements 36 to engage against the sole blanks .18 as they are placed between the guides 16 =and 17. A rack or supporting magazine 37 is conven- ..:iently secured to the upper end of standard 10 through an arm 38. In use of the apparatus, it will be obvious that as the blanks are drawn along the rollers 12, in alignment with the slot 14 thereof at thenarrow end of the slot and cause them to travel along'this slot, they will, upon arrival at a point where the Width of the slot is greater than their thickness, pass through'this slot and thus come into engage ment with rollers 13 which will grip: the

blank and-cause it to be discharged downwardly. To assist in this gripping-action, the faces of rollers 13 are preferably covered with friction material, as indicated at 39,

and this material is preferablyof sucha nature that it is resilient. Rubber maybe conveniently employed. 7

The standards 10 and 11 are preferably employed to support receivers 40, these receivers "being atpresent illustrated the forni of chutes adapted to discharge into movable bins generally designated in dotted 'lines'Iin Fig. 1. "In order that these bins may be made of sufiicient sizeto hold ai rea-c son ablei quantityiofblanks and, at the same time, adequate space imay be pr0videdtherefor, alternateflchutes 41 preferably discharge infopposite directions,ras indicated. It will,'; 1 0i course, be obvious that this arrangement isentirely arbitrary and that other means ffortaking' care of thesortedtblanks than notendency -to wedge in the slot as would" ns ordinarily be the casewere al'slot' employed that shownmay beemployed;.

1 Attention'is directedto the fact th at since '18 with the resultthat the blanks will have having a tapered mouth, such asis afforded by therollers.

Since the construction illustrated is capable of a very considerable change and modification without in' any manner departing from the spirt of my invention, I donot wish to limit myself to the specific structure a tapering slot varying in width from'end to end, a series of receivers arranged there'- beneath, means'for causing articles to shift longitudinally of the slot untiltheir arrival at a point where they may pass therethrough, means engaging an article after a predetermined portion thereof has" passed through the slot and 'discharging'the same to the underlyingreceiver, and means guidlng the article during 1ts travel along the? slotmaintaining the same in alignment with the slot and said engaging means. 3.
