Specification of Letters Patent.
Patented July 11, 1911.
Application filed August 25, 1910. Serial No. 578,833.
To all whom it may concern:
Be it known that I, F REDERICK C. BRITT, a citizen of the United States of America, residing at Middleport, in the county of Niagara and State of New York, have invented new and useful Improvements in Bean-Pickers, of which the following is a specification.
This invention relates to bean pickers, and it has for its object to produce a device of simple and inexpensive construction which may be efficiently utilized for the purpose of separating sound and good beans, peas and other grains from defective ones and from dirt, grit and the like.
With these and other ends in view, the invention consists in the improved construction and novel arrangement and combination of parts to be hereinafter fully described and claimed.
In the drawings,Figure 1 is a side elevation of a machine constructed in accordance with the invention. Fig. 2 is atransverse sectional elevation taken on the plane indicated by the line 2-2 in Fig. 1. Fig. 3 is a sectional view taken on the line 3-3 in Fig. 2. Fig. 4 is a sectional detail view taken on the line 4l4l in Fig. 2. Fig. 5 is a sectional detail view taken on the line 5-5 in Fig. 1. Fig. 6 is a detail plan view of one of the apron carrying tables or supporting frames. Fig. 7 is a sectional detail view taken on the line 77 in Fig. 3.
Corresponding parts in the several figures are denoted by like characters of reference.
The improved machine includes a frame structure A which is provided with bearings 1 for a longitudinal main shaft 2 which is arranged about midway between the sides of the frame and which may be driven in any convenient well known manner from any suitable source of power. The main shaft afiords a support upon which bracket members 3, 3 are pivotally mounted, two or more such bracket members extending from. the main shaft toward each side of the machine and serving to support the picker frames B which may be bolted or otherwise suitably secured upon said brackets, there being one such frame at each side of the machine. The outer sides of the frames B are connected by flexible elements, such as chains 4 with suitably arranged drums or shafts 5 having cranks 6 whereby they may be rotated to wind the chains and equipped with ratchetwheels 7 engaged by pawls 8.
for the purpose of securing the parts at the desired adjustment. It will thus be seen that each picker frame B may be supported securely in a tilted or inclined position, said picker frames being inclined downwardly from the center of the machine in an outward direction.
Each of the picker frames may consist of a suitably constructed frame of rectangular shape provided adjacent to the ends thereof with bearings 9 in which shafts 10 carrying rollers 11 are supported for rotation. The rollers 11, 11 at the ends of each frame serve to support an endless apron or carrier 12. One of the roller carrying shafts 10 of each frame is provided with a bevel gear 13 meshing with a bevel gear 14: upon the driven main shaft 2 from which motion will thus be transmitted to the endless apron or carrier at each side of the machine. The carriers may be driven in opposite directions, as indicated in the drawing, or both carriers may be driven in the same direction, if preferred, by a simple and obvious change in the arrangement of the transmission gears. It is also obvious that the transmission gears are to be so arranged as to remain in mesh at any adjustment of the pivotally supported frames with reference to the shaft about the axis of which said frames are adjustable.
Each of the rectangular frames B supports a platform or table 15 which serves to support the upper lead of the endless apron or carrier '12. This table or platform may be integral with the frame or it may be secured thereupon by bolts, rivets or in any other suitable and convenient manner. It is also desired to be understood that the precise form or structure of'this supporting device may be modified in various ways, the object being to prevent the upper lead of the apron or carrier from sagging under pressure except at certain points where the said table or platform is provided adjacent to the upper sides of said lugs with non-circular enlargements for1ning wrench seats 20 and adjacent to the undersides of the lugs with heads 21 serving to secure the bolts with reference to the lugs 18 in such a manner that said bolts may be rotated by applying a suitable tool, such as a wrench or spanner, to the seats 20. The threaded ends of the supporting bolts are extended through correspondingly threaded lugs 22 formed upon a frame C which is thus supported adjustably with reference to the frame B. Each frame C carries a plurality of rollers 23, 23 which are adapted to bear against the upper or outer face of one of the endless aprons or carriers 12, the degree of pressure being readily adjustable by means of the bolts or supporting members 19. The rollers 23, 23 are provided with intermeshing gears 24, 24, and it is desired to be understood that while the rollers are preferably of equal diameter, the gears 24 of alternate rollers 23 are larger than those ofthe intermediate rollers 23, thus causing the rollers 23 to be rotated not only at a greater speed, but in a reverse direction to the rollers 23. The latter, which are designated the picking rollers in contradistinction to the rollers 23 which are known as cleaning rollers, are arranged directly above the slots 16 in the belt supporting table, thus permitting the belt to sag slightly at the points beneath the rollers 23, while beneath the rollers 23 sagging is rendered impossible by the presence of the solid portion of the table or supporting member 15. The roller carrying shaft 10 associated with each frame is provided with a cog wheel 25 in termeshing with one of the gear wheels 24, thus transmitting motion to the entire set of rollers.
The beans that are to be cleaned are fed to the belts by means of a hopper 27 having spouts 28, said spouts being arranged to discharge beans upon each belt or carrier 12 adjacent to and in advance of each of the picking rollers 28. The receiving tanks or vessels 29 are suitably supported adjacent to the sides of the frame structure for the purpose of receiving material that is discharged over the lower edges of the belts or carriers. The receptacles or tanks are disposed adjacent to the spaces between the rollers, a separate receptacle being provided for each space. It is obvious that in view of the receptacles herein shown receiving chutes may be provided having connections whereby material will. be conveyed to suitable bins provided for the reception of the sound beans and the refuse matter, respectively.
In the operation of the invention, the material to be cleaned and separated is discharged through the spouts 28 on to the endless belt or carrier adjacent to the picking rollers which rotate in the direct-ion of the lead of the belt adjacent to which they are supported. The soundbeans, which are comparatively large, smooth and regular will not be engaged by the picking rollers, but will slide along the latter and be discharged over the edge of the belt. The refuse beans, Which are relatively small and of irregular shape, as well as particles of grit, dirt, gravel and the like, will be engaged by the picking rollers and carried thereby between the rollers and the belt, which, as previously noted, is permitted to sag beneath the picking rollers, such refuse material being carried onward to the cleaning rollers which are rotated in a direction reverse to the movement of the belt, the refuse material being swept aside and off the belt by the action of said rollers. The picking rollers, moreover, are disposed 0pposite to the solid portions of the belt supporting table, so that sagging of the belt at these points will be impossible, rendering it impossible for any of the refuse material to be conveyed past the cleaning rollers.
This device, as will be seen from the foregoing description, is simple in construction and thoroughly effective for the purpose of picking or separating sound and high class beans from the inferior beans and refuse matter.
