7 Claims. (Cl. 198-56) This invention relates to a hand bean picker or means for spreading beans or other articles or materials before inspection so that discards may be removed by hand.

It is particularly aimed to provide such a structure having a conveyor capable of operation manually or by power as preferred, a structure which is foldable or collapsible to occupy minimum space, a structure wherein the belts mayv be effectively tensioned and the mounting of which coacts lwith the adjustment of the legs or supports oi the structure, and a structure having a removable hopperto coact with the conveyor and provided 'with means to cut oli the same incidental to removing. Y The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings: l

Figure 2'is` a plan View thereof;

Figure Al is a cross sectional view taken on the line Rueil of Figure 3; Figure l5 is a cross sectiontaken on the line 5h15 of Figure 3;A

Figure 6 is a cross section taken on the line 6-6 of Figure 3; Y

Figure '7 is a detail of gear means which may be employed to power-operate the apparatus;

Figure 8 is a cross section taken on the line 8 8 of Figure 3;

Figure 9 is a detail section taken on the line 944i of Figure l;` and Figure 10 is a cross sectional view taken on the plane of line Ill-ill of Figure l.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, the framework of the apparatus or machine consistsV for instance of a table generally kdesignated Il) and which may comprise parallel side beams I I spaced apart and rigidly connected together by battens I2. Front and rear supports are provided at I3 and'I 4. The rear support ccnsists of spaced apart 'legs I5 connectedV at the top by a cross batteri I6 and adjacent the bottom by a cross brace I'I. A pair of bolts I8V connect each leg I5'to a side beam I I. One or both of the bolts i8 of each pair is removable so that the remaining bolt will provide an axis to enable the front support I3 tov be folded upwardly and inwardly according to the dot-'dash lines Vand arrows in Figure 3. As to the hind or rear support 14, it consists of a pair of spaced apart legs I3 connected rigidly at the top by a batteri 20 and at a vlower elevation by a cross brace 2|. The legs I9 are secured by a pair of

bolts

22 and 23, a pair for each leg I9, securing them to the adjacent side beam I I. The bolts 23 are passed through arcuate slots 24 in the legs and are adjustable, so'that their nuts may be loosened to enable the rear supporting structure I4 to be folded inwardly and upwardly in the path of the dot-dash lines and are rows shown in Figure 3. At the same time, the nuts of the

bolts

22 and 23 will rigidly secure the legs IS in place.

An endless conveyor is horizontally disposed above the table II at 25 andrmay consist of any flexible material for instance canvas. Such cone' veyor is trainedover rollers 26 and 2l, at its front and rear ends, respectively, the rollers having flanges 28 to conne the belt or conveyor to the proper path. Such belt or conveyor also has its side edges doubled or reinforced as at 29. This feature also aids in preventing bean-s from moving laterally off the conveyor. y

Rollers 25 and 2l, are mounted respectively on

shafts

29 and 33, respectively, journaled at both ends preferably in roller bearing structures 3! as detailed in Figure 6, in bearing members32 and 33, respectively. The lower edges of the bearing members 32 fit and rest on the upper edges of the legs l5 and batten I6, and bolts 34 removably secure such bearing members 32 to the batten IE.

The bearing members 33 are detachably'secured by screws or bolts 35 to the batten 20. Bolts 35 pass through elongated slots 35 in the bearing members, enabling the bearing members 33 to be adjusted in an angular path parallel tothe upper edges of the legs I9 and batten 20. In addition, the arcuate slots 24 enable the legs I9 to have pivotal movement on the bolts 22 in order to afford sufcient leverage to properly tension the belt or conveyor 25.

At the feeding end of the frame IIJ, the latter has suitably secured extension bars 31 provided with vertical holes or openings detachably interengaged by studs or dowels 38 carried by bars 39 secured on opposite sides of a feeding hopper H. The beans or articles to be picked or sorted are supplied into the open end of said hopper H. The mentioned openings in bars 3l occupied by the studs 38 are designated 4B. To prevent accidental detachment of the hopper from the table or bars 3l, a transverse bolt 4I may be removably passed through a suitable part of the hopper and the bars 31. Also, at one side of the hopper, it is provided with an L-shaped opening 42, affording clearance about the shaft 29, for attachment and detachment of the hopper. Said shaft 29 may be driven or operated in any suitable manner, that is, manually or by power.Y In the latter event, a belt drive may be connected to the pulley 43 or in lieu of the pulley 43 I may provide a gear wheel 44 on the shaft 29 as show-n in Figure 7, and drive gearing be operatively associated with the gear 44 and a source of power.

The hopper H has an elevated bottom consisting of downwardly c-onverging

sections

45 and 46 spaced apart or provided with a discharge opening 4'! through which the beans or articles fall onto the conveyor 25 so as to be drawn out of the hopper H and to be sorted or picked by operators standing or seated on either or both sides of the conveyor between the hopper and the opposite end of the apparatus.

An adjustable double slide gate is provided in the hopper for the opening 4l. The slides or gates are respectively designated 49 and 54 and are disposed on opposite sides of the bottom section 46 and movable through

openings

50 and 55, provided in the front wall 5l of the hopper. Said wall 5I also has an opening at 48 to provide clearance for reception and operation of the conveyor y 25. Guide rails or bars are provided at each side ofV the slide 49 and the latter may have spring or clasp fingers 52 gripping such guide rails, as shown in Figure 5, to hold the slide adjustably in any position to which it may be moved. The adjustment of the slide 49 determines the extent of opening 4l which is exposed for passage of the beans to the conveyor, in order to regulate such passage. The other slide 54 has guides 51 at each side thereof and has spring or clasp lingers 56 engaging the same, to hold the slide 54 in any adjusted position. The slide 54 is provided preferably to entirely close or cut off the opening 4l preparatory to removing the hopper H as when transporting or storing the device. It will be noted that on the under surface of the floor section 45, felt or other packing or filler material 59, may be provided in any desired conguration in order to prevent falling or escape of beans from the conveyor at the left hand end. Y

On each side of the table suitable receptacles 60, into which the picker or pickers deposit thel bad beans, are provided. These receptacles may be of any desired size and shape but at their open ends they preferably extend under the upper run of the conveyor 25. They may rest across the battens I2 and be secured against accidental displacement by means of nails or other pegs i removably placed through openings in the bottom of the receptacles Si! and openings S2 in the rails or beams i i of the table. The good beans preferably fall off or are discharged by the conveyor at the right hand end into a suitable receptacle. Such receptacle may be the ordinary burlap bag (not shown) suspended from hooks 63 carried by the bearing members 33. Obviously, in lieu of bags, backets or any other receptacles `may be placed on the ground beneath the right hand end of the conveyor in order to catch and retain the goods beans.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.
