Specification of Letters Patent.

Patented Oct. 30, 1917.

Application filed March 17, 1916. Serial No. 84,888.

To all whom it may concern .1

Be it known that I, FRANK CAnsoN, a

citizen of the United States, residin at Caro, in the county of Tuscola and tate of Michigan, have invented new and useful Improvements in Sorting Devices, of which the following is a specification.

This invention relates to sorting devices which are utilized to separate defective beans and other objects from perfect ones of their kind, the invention havingspecial ref-, erence to that class of devices in which the objects to be separated are carried by a conveyer in full view of the operator or attendant, said conveyer having pockets or cells with yielding bottom members through which the defective objects may be pushed by the fingers of the operator, leaving the perfect objects to be discharged over the conveyer.

One object of the invention is to simplify and improve the construction of the endless conveyer which constitutes an important part of the device.

Another object of the invention is to produce simple and improved means for conveying the objects from a source of supply and depositing the same in the cells or pockets of the conveyer.

A further object of the invention is to produce a cylindrical distributing member,

operated in conjunction with the endless.

conveyor and adapted to distribute the objects to be separated in the pockets of the conveyer, one object in each pocket.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has. been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims maybe resorted to when desired.

In the drawings,-

Figural is a top planview of a machine constructed in accordance with the 1I1VeI1-' tion.

Fig. 2 is a side elevation.

Fig. 3 is a longitudinal vertical sectional view taken on the line 3-3 in Fig. 1.

Fig. 4 is a transverseseotional view taken on the line 4-4: in Fig. 1.

Fig. 5 is a perspective detail view of the distributing cylinder.

Fig. 6 is a sectional detail view, enlarged, of a portion of the endless conveyer taken on the line 6-6 in Fig. 1. h

Fig. 7 is a bottom plan view, showing a small portion, of the top lead of the endless conveyer. I

Fig. 8 is a top plan view of the same.

Fig.9 is a sectional detail view taken on the line 99 in Fig. 2.

Fig. 10 is a sectional detail view taken on the line 1010 in Fig. 2.

Corresponding parts in the several figures are denoted by like characters of reference.

The main frame 15 of the machine is provided with bearings for

shafts

16,17 and 18 over which an endless conveyer C is trained,

said shafts being] provided with sprocket wheels 19 engaging the links of the conveyer. The boxes or bearings of at least one of the shafts are adjustably connected with the frame by means of set screws 20, this construction being shown applied tothe shaft in Fig. 2 where one of the bearings is indi cated by 21, and the set screws 20 areshown extending through a slot 22 in the frame.

This construction enables the conveyer C to be properly tensioned so that the top lead of said conveyer will be maintained in a level condition, the supporting shafts 16 and 17 being arranged substantially in a horizontal plane, and the sprocket wheels 19 being of equal size.

The conveyer C in its preferred construction comprises chains 23, one at each side,

- relatively near the cross bars 25 which, are

at the front with respect to the upper lead when the conveyer is moving in a direction r- I The charts 39, i0 and ll indicated by the arrow in Fig The seteral pockets are proiided with leaves or bottom members the same being hingedly connected with the cross bars '25 and positioned with their free ends beneath and abutting on the cross bars 2%, each bottom member being pressed by the arm of a spring, a portion of which is coiled about one of the cross bars 25, as seen at 31, s spring having another arm 32- that engage the cross bar 223. It will be seen that by thi. simple construction, the endless coni'eyer, is made to comprise a' large nurnber of pool;- ets, each of: which has a yieldably supported leaf or bottom member which may be readily depressed against the tension oi it actuating spring to enable an object supported thereon to be pushed through the top leaf of the conreyer. It will also be seen that by properly spacing the cross bars 28 from the cross bars 25, the said cross bars 28 will not lie in the path of an object that is being pushed over the supporting leai or bottom member which is directly in the front thereof, as seen in Figs. 6 and 7. TL, entire con eyer being constructed of meta will be rigid, and will not be liable to sit when in operation, especially when properly tensioned by previous adjustment or the,

tensioning shatt- 1S1 The frame of the machine supports at one 7 end thereof the receptacle 33 in which operates a feeder F which consists of an and less conyeyer composed of slats 3% which are flexibly connected together by means of linkvbelts 35 trained over sprockets 36, 37, and 38 on shafts 39, 40 and il, said shafts being supported for rotation in boxes or bearings carried by the frame structure. arranged the corners f triangle, the apex of which dips into the receptacle 33. The boxes in which the shafts 39, M) are supported for rotation.

are vertically adjustable in guides 42 by means including screw threaded rods 43 and wing nuts is, thereby enabling the con veyer chains 35 to be tensioned or tightened as may be required. the shaft a l are longitudinally adjustable with respect to the longitudinal trance bars 46, on which they are mounted, byineans of set screws l? engaging theboxes 48 through slots Al in the frame bars e 6, thereby enabling the lowermost portion of the conveyer or feeder, l to be adjusted longitudinally to the. most advantageousposition.-

Theslats 34 of the feeder, F are provided with cups 50, each of said cups being: of a supportsthe feeder F also supports a shield 51 fwiuclr sd1sposed adgacent to-the rearv The boxes supporting nae-spec ward lead of the feeder, said shield being equipped with a plurality of chutes 52 forined by partitions 53 and rear wall portions 51, the latter being provided at their upper nds with rearwardly extending to u s 55 pointing in the direction of the torn .rd lead of the feeder. The chutes 552 are arranged in registry with the cups 50 on the feeder slats so that the contents'of' the separate cups will be dumped or discharged into separate chutes. The shield 51 and the rail member at which constitute, respectively, the front and rear walls of the chutes are provided at their, lower ends with is provided with sprocket wheels 63 engage,

ing the conveyer chains 23, so that the distributing; cylinder will be operated by and concurrently with the conyeyer Gin such a fashion that the contents of each otthe cells 62 ofthe distributing cylinder will be discharged into one of the pockets D of the c con eyer.

The shaft 39 of thei eeder F may be'driven by a inotioi transmitted thereto means from the shaft 16. The marably driven by power applied 1'? at the discharge end of the saio shaft 17 been shown i. i i a band wheel 65, although is to be understood that the machine to the point shall, be ,garded as most convenient. in the operation of thisdevice, the beans or other objects that are to be separated are. The feeder F' placed in the receptacle ha ing the cups 50 will lift the beans from the receptacle and carry them to the chute.

52, whereby they areconveyed to the cells of the distributing" cylinder, which, latter, being operated conjointly with, the conveyer C, will serve to distribute the beans singly in the pockets llthearrangementbeing such that a bean will be placed in each one of the pockets. The beans will thus be spread out evenly before the gaze of-the' operator who by pressing, or pushing the defective beans will force the same through the top lead of the con eyer, and into the pan or receptacle 66 placed underneath.

The good beans will be discharged over the tail end or? the converter (3 to suitable r ceptacle provided for the purpose but not shown. It is obvious that the machine may be speeded to suit the skill and convenience of the operator.

l'iiaving thus described the invention, what is claimed as new is 1. in a machineof the class described an endless conveyor having a substantially horizontal top lead, said conveyor being proided with pockets arranged in transverse and also in longitudinal alinement, in combination with a distributing cylinder supported for rotation adjacent to the top lead of the conveyor, said cylinder having rows of cells each corresponding with a transverse row of pockets in the conveyer, means for feeding material to the distributing cylinder, and means for rotating the cylinder concurrently with the operation of the conveyor to space the rows of cells in the distributing cylinder successively in discharging relation with respect to the rows of pockets in the conveyor.
