ABRAHAM BRUBAKER, OF WARSAW, INDIANA.
PE A- GRADER.
Specification of Letters Patent.
Patented Aug. 25, 1908.
Application led January 6, 1908. Serial No. 409,515.
To all whom it may concern:
Beit known that I, ABRAHAM BEUBAKEE, a citizen of the United States, residing at Warsaw, in the county of -Kosciusko and State of Indiana, have invented a new and useful Pea-Grader, of which the following is a speciiication.
This invention relates to grading machines and more particularly to a machine for separating and grading peas.
The object of the invention is to provide a grading machine in which the separation of the larger peas is initially effected and the smaller peas subsequently graded thereby to prevent the smaller peas from being carried along in bulk with the larger peas.
A further object of the invention is to provide a grading machine including a plurality of perforated concentric kcylinders spaced apart to form intermediate compartments for the reception of the peas, said cylinders being mounted for rotation having a series of tappets associated therewith and adapted to bear against the perforated walls of the cylinders thereby to prevent the peas from lodging in the perforations or against the walls of said cylinders.
A still further object of the invention is generally to improve this class of machines so as to increase their utility, durability and e'fliciency.
Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.
In the accompanying drawings forming a part of this specification: Figure 1 is a side elevation partly in section of a pea grading and separating machine constructed in accordance with my invention. Fig. 2 is an end view of the same. Fig. 3 is a detail sectional view showing the manner of connecting the perforated cylinders.
Similar numerals of reference indicate corresponding parts in all of the figures of the drawings. Y
The improved grading machine forming the subject matter of the present invention includes a supporting frame preferably rectangular in shape, as shown, and comprising longitudinal bars 5. connected by, spaced transverse bars 6 and 7.
Secured to the transverse bars 6 are suitable bearings 7l in which is journaled a longitudinal shaft 8, the latter having keyed or otherwise rigidly secured thereto a central wheel or spider 9.
The wheel or spider is provided with a plurality of radiating arms or spokes 10 preferably four in number, as shown, and which form supports for a plurality of spaced longitudinal arms or braces 11. The longitudinal arms 11 are each preferably formed of a single piece of metal having its inner end bent laterally to form a iiange 12 for attachment to the adjacent radiating arm of the spider, said radiating arms being preferably rectangular in cross section so as to permit the liange 12 to fit snugly against the adjacent wall of said arm.
Riveted or otherwise rigidly secured to the longitudinal arms 11 are a plurality of concentric cylinders 13 spaced apart to form intermediate compartments 14 and having their side walls formed with a series of perforations 15, the perforations in the several cylinders gradually decreasing in size from the inner cylinder to the outer cylinder -so that when the peas are discharged on the interior walls of the inner cylinder, all-except the largest peas will pass through the perforations in the inner cylinder into the next compartment 14, while the smaller peas will pass through the smaller perforations in the succeeding cylinders into-the adjacent compartments from whence they are discharged at one end of the machine.
The longitudinal arms 11 oneach side ofV the spokes 10 are preferably disposed oney slightly above the other while the adjacent4 sections 16 and 17 of each screen are connected by an inclined plate or member 18 having one end thereof disposed beneath the section 17 and the opposite end arranged in contact with the inner surface of the section 16 thus forming a guide for the peas and preventing the latter from lodging between the spokes.
Secured to the opposite transverse plates 6 of the supporting frame are brackets 19, each having its free end deiiected upwardly andv extended transversely across the adjacent ends of the cylinders and provided with a plurality of spaced longitudinally disposed rods 20. The upper rod 2O extends on the outside of the outer perforated cylinder and serves to connect the brackets 19 while the intermediate rods terminate at a point adjacent the arms or spokes 10.
Pivotally mounted on the vrods 20Waew plurality of weights or tappets 2-1 which bear against the exterior walls of the adjacent. perforated cylinders and serve to prevent the peas Afrom lodging in therperiiorations of said* cylinders or against the Walls ofthe latter. The pivoted ends of the tappets21 are each formed with a lateral extension or collar 22.* which bears against the collarofan adjacent tappet,.thereby to properly space the tappets and prevent vaccidental displacement ofthe same.. rPhev eas are discharged on the interior walls o the inner cylinder 1-1l through a.
Y spout- 23, the latterV being arranged beneath the longitudinal shaft 8 and providedwith a flexible sleeve 24 which bears against the adjacent wall of the inner cylinder, as shown there being a trough 25 communicatingwith each compartment 24 Jfor discharging the peas from saidcompartments into suitable` bins or receptacles 26 designed to receive theV same. H
The machine may be operated either manually or from any suitable source of power and in the present instance one end'of the shaft 8 is shown extended longitudinally beyond the adjacent cross beam 6 and provided with a pulley 27 having a belt 28 mounted thereon and operatively connected with an engineer other source of power. Y
The operation of the device'is asrollows: The peas are discharged through the spout 23 from the blower of a fanningmill and deposited on the interior walls of the inner cylin der, motion having been previously imparted tothe several cylinders through the medium of the pulley and belt. As the peas are discharged into the machine thelargest peas will roll down the inclined interior walls of'y the inner perforated cylinder'into the upper spout 25, while the next Ylargest peas willV pass through the perforations in said cylinder into the ladjacent compartment 14 from whence they are discharged through the next spout 25 into one of the receptacles 26, the smaller peas dropping through the perforations in the remaining screens into the adjacent compartments from whence they pass into the continuous spouts 25 and thence into the receptacle 26, thus thoroughly and e'lectually separating and grading the peas.
Attention is here called to the fact that the discharge end of the cylinder isslightlyf It will of course be understood that the peas may be discharged onto a suitable separating tableV having the usual pockets for the Yreceptin odirferent grades of peas instead -Jol'employi-ng the receptacles at the lowerend of thelnachine.
