DISK-SORTING MAcHINE.

T 0 all whom it may concern:

Be it known that I, THOMAS ALLATT, a sub ect of the King of Great Britain, and

a resident of New York, inthe county of with a view to remove the defective-or objectionable ones. 7

In machines of this type, the disks are fed by suitable means onto the 'conveyer, the attendant sitting next to the said conveyer examining and sorting the same as they travel past the seat. The disks are continuously fed onto the conveyer andtravel thereon in a mass, a few, say two or three, one on top of another, so that the attendant is compelled first to separate the disks in order to be able" to inspect and sort the same.

The main object of the present invention is to provide a simple and efficient means for separating and distributing the disks on the conveyer so that they move in a continuous stream past the attendant but one deep, or in other words side by side, but never one on top of another.

With these and other objects in View which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from-the spirit or sacrificing any of theadvantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings,in whichzv Figure 1 is a vertical centralsection taken through a disk sorting machine constructed in accordance with the present invention; Fig. 2 .is a section taken on line 22 .of Fig.1; Fig. 3 is a section taken on line .3 of Fig.- 2, n a larg r scal 4 and 5 are vertical sections, on a larger scale, taken through the separating and distributing means; and Fig; 6 is a similar sectiontaken through a detail of construction of .said separating and distributing means.

1 In the drawings, the numeral 10 indicates a frame, supported by legs or standards 11. On this frame is mounted a screen 12, comprising a perforated plate 13, having side flanges 14:. These side flanges are connected .with the frame 10 by resilient slats 15, to permit of a vibrating or'reciprocatingmotion of said screen. The screen receives the cork disks from a receptacle '16, the'means for supplying the disks from the said receptacle to the said screen being not shown, as they do not form part of the present invention. Vibrating orfreciprocatlng motion is imparted to the screen by means of a crank 17 on adriving shaft 18, the latter beingrotatably mounted on the frame 10 andreceiving motion from: any

the intermediary of a belt 19 that runs over a pulley 20 on the said'drivingshaft; The crank is connected by-a, preferably, flexible rod 21. with the screen, one end of said rod being attached to a bushing 22ion the pin 23 0f the crank, and the other end of said rod being fixed to the forward end of said screen, as clearly appears from Fig. 1 of the drawings. The screen is inclined toward its open front end, delivering the disks to a conveyer 24 of the belt-type. i

' The belt of he conveyer runs in the wellknown manner over rollers, one of the same, denoted by the numeral 25, being shown in the drawings, receiving motion, from any suitable source of power, in the direction of the arrow shown in Fig.1 ofthe drawings. The acting portion of the belt, that is to say that part thereof which transports the disks from the screen forward, is disposed a slight distance below the screen and is arranged below the distributing and 'sepa rating means 26. This means comprises a transverse bar 27 that is suspended from a transverse'shaft 28 on the frame 10 by arms 29, the upper ends of said arms being hookshaped, as shownat 80, and in engagement Specification of Letters Patent. Patented NQ .:25, 1919. l Application filed March 28, 1919. Serial No. 285,871.

suitable source of power, for instance by with the shaft 28, thereby permitting of a permit the disks to pass below the same on the belt conveyer side by side, butnever one ontop of another. The bar 27 is connected with the screen 12 by, preferably, resilient slats 27, so that it moves with the said screen.

With the bar 27 is associated a rake 31, including spaced teeth 82, which are loosely mount-ed upon a rod 33, that is oscillatably journaled in lugs 3-1, the latter extending forward of and being attached tothe bar 27.

The teeth extend in rear of the bar 27, resting upon a transverse support 85, that is fixedly attached to levers 36, which, in turn, are rigidly secured to the rod 33. To the free end of one of these levers is pivoted a connecting rod 37, the other end of which is fiXed to a sleeve 38, that is drawn over a pin 39 on a bell crank lever 40, the latter being fulcrumed at 41 to oneof the side flanges 1a of the screen 12. To the bell crank lever is furthermore pivoted at 42 a link as, the other end of which is pivoted at 14 to a flexible connecting rod 45, one end of which is attached to a bushingl6 on the pin 47 of a crank &8, that is keyed or otherwise secured to the driving shaft 18. The other end of said flexible connecting rod is secured to a rearwardly inclined trough 49. that is disposed below the screen 12 and suspended from the frame 10 byresilient slats 50.

The screen and trough move in'opposite directions, the trough receiving the broken disks, chips, etc, from the screen and de' livering the same into .a receptacle 51 below the discharge end of said trough.

The teeth 32 of the rake arespaced apart, a distance that is greater than the diameter of the disks to be sorted, by suitablespacing means, for instance in the form of sleeves '52, that are drawn'over the rod 33. p The free ends of the teeth extend downward toward the acting portion of the belt conveyer and in their lowermost position (Fig. 4) are spaced from the said conveyer a distance that is, preferably, smaller than the thick ness of the disks on the conveyer.

The operation of this'deviceis as fol 'lows:-The disks, to be sorted, are supplied from the receptaclel6 in either a continuous or intermittent stream onto the screen 12, which advances the same to the conveyer 24'. As the conveyer moves in the direction shown by the arrow in Fig. 1 of the drawings', the disks are brought first withinthe reachof the rake 31 and then inoperative relation to the bar 27. This bar swings around the shaft 28in unison with the screen 12, taking with it the' rake, theteeth of which, however, are actuated by the connecting rod 37 and the 'mechanism associated therewith; This. mechanism is so'timed, that, whenthe bar 27 movesin thedirectionof the movement ofthe acting portion of the belt conveyer, the 1 said teeth arein their lowermost positions (Fig. 4), in which the free ends of said teeth are disposed at a slight distance above the belt conveyer. When the bar 27 moves in the opposite direction, the connecting rod 37 tilts the levers 36, thereby lifting the said teeth into the position shown in Fig. 5 of the drawings, in which position they remain substantially to the end of the stroke of the bar 27 being lowered immediately before the said bar starts its movement in the direction of the movement of the acting portion of the belt conveyer. By so timing the movements of the bar .27 and the teeth of the rake, the said teeth, when in their lowermost positions, move in the direction of the arrow shown in Fig. 4 of the drawings, spreading and distributing the disks within reach over the entire width of the conveyer, here and there removing disks from the lowermost layer. They also have a tendency to keep the disks close to the bar 27, which allows the disks but one deep to pass under it on the conveyer, removing disks on top of the lowermost layer in its movement in the direction opposite to that of the'acting portion of the belt conveyer.

The attendant inspects the disks in'front of the spreading and distributing'means, removing the imperfect or defective ones. In asniuch as these disks are transported past the attendants seat but one deep, the attendant is in a position to readily distinguish the defective disks without handling the same.

It is obvious that, while herein a specific means has been described for actuating the screen and trough, and the spreading and distributing means has been shown as being driven by the said screen and trough, any other means may be used for thispurpose without departing from the invention, which lies mainly in the provision of a swinging frame having a transverse bar disposed at a distance from a beltconveyer that is somewhat greater than the thickness of thecork disks, in combination witha rake upon said frame havingoscillatable teeth for the pa pose specified.

The shaft '28 may; be eccentrically mount ed upon'disks 53, said'disks-being' seatedin circular recessesb'i in the" frame 10." By shifting the disks 53 in' their respectivere cesses, the distance between the bar 27 and the belt-conveyer may be: adjusted atwill; What I claim is 1.
