(Cl. 209-358) This invention relates to the oilicial class of material handling and assorting and more par ticularly jarring screens.
The primary object of this invention resides in the provision of a screen for coal, rock and other similar material adapted to operate without shaking the hopper.
Another object of this invention resides in the provision of a screen for coal, rock and other similar material adapted to agitate the same so the smaller sizes thereof will gravitate andthe larger sizes will be advanced therethrough to a separate container.
A further objectl of this invention resides in the particular construction and operation of the material agitating and advancing means.
A still further object of this invention resides in the particular construction of the supporting bed for the agitators.
Aside from the aforesaid objects this invention resides in the particular construction of the agitators.
Among the many objects of this invention is the particular construction and assemblage of the agitator operating means.
One of the salient features of this invention resides in the particular manner of assembling the agitators on their shafts.
With these and other objects in view this invention resides in certain novel features of construction and arrangement of elements to be hereinafter more particularly set forth in the specification, illustrated in the accompanying drawings and pointed out in the appended claim and, while this disclosure depicts my present conception of the invention, the right is reserved to resort to such changes in construction and arrangement of elements as come within the scope of the claim.
In the accompanying drawings forming a part of this application;
Fig. l is a side view of the screen.
Fig. 2 is a plan view thereof.
Fig. 3 is a longitudinal sectional view thereof approximately on line 3 3 of Fig. 2.
Fig. 4 is a cross sectional view approximately on line 4 4 of Fig. 1.
Fig. 5 is a cross sectional View of the agitator bed and agitators removed from the hopper.
Fig. 6 is a detail perspective View of one of the agitator supporting and operating shafts.
Fig. 'l is a detail perspective view of a portion of the agitator bed.
Fig. 8 is a detail perspective View of one of the agitators.
In the present embodiment of this invention the numeral 5 designates, in general, a coal, rock or other similar material separating screen consisting of a suitable stationary hopper 6 having a depending chute 'l for conveying smaller sizes of the material to a suitable bin and an end chute 8 for conveying larger sizes of the material to another bin not shown, said hopper is preferably supplied with material to be screened through the instrumentality of a suitable feed chute 9.
Disposed in the hopper 6 is an agitator bed Ii! consisting of a plurality of longitudinally extending plates H having a series of laterally aligned apertures l2 adapted to rotatably receive laterally extending shafts i3 of rectangular or other similar conguration, said shafts have their opposite ends I4 extending through the hopper and journalled in suitable bearings l5 fastened to the outer sides of the-hopper.
Mounted on the shafts between the longitudinally extending plates H is a multiplicity of agitators I6 adapted to be disposed a predetermined distance apart to provide exit passages Il therebetween to permit smaller' sizes of material to gravitate to the chute 'I at which time the larger sizes are kicked upwardly and advanced toward the chute 8 from which they are conveyed to a suitable storage bin.
The aforesaid plates H are spaced apart approximately a distance equal to the greatest ydistance between the hubs of the rotating agitators I6 so as to prevent sizes of material considerably greater than the spaces Il from gravitating onto the agitators, thus it is apparent the larger size of material will rest on plates Il and be `pushed toward the chute 8 by the free ends of the agitators as they rotate above the upper edges of the plates.
The aforesaid plates Il are retained'in aligned spaced relation by cross-bars I8 to provide channels IQ for reception of the agitators and to retain the material therebetween during the process of separation.
Keyed to the shafts I3 outwardly of one side of the hopper are worm gears 2D meshing with worm-teeth 2l on a drive shaft 22 mounted on the hopper by suitable bearings 23, said shaft is driven by an electric motor (not shown) or any other suitable source of power.
Through the provision of a screen constructed as herein set forth, material such as coal, rock and the like is conveyed thereto through the feed chute "9 between the plates Il and onto the rear series of rotating agitators, operated through the instrumentality of the worm gears and drive shaft, whereupon the material will be jarred causing the smaller sizes thereof to gravitate between the agitators while the larger sizes will continue in a course toward and over the end chute.
With a screen constructed as aforesaid it is manifest that means are provided whereby coal, rock and the like can be sifted and assorted in a stationary hopper and, throughv the particular assemblage of separating and operating means therefor, the minimum cost of manufacture and operation will prevail.
Having thus described my inventionwhat I claim and desire to protect by Letters Patent is:
A sifting and asserting screen comprising, a stationary hopper having its opposite sides provided with aligned enlarged apertures, crossbars secured at their ends to the innerl surfaces of the aforesaid sides of the hopper, a plurality of longitudinally extending plates secured at their lower edges only to the cross-bars and having enlarged apertures therein aligning with the apertures in-the sides of the hopper, shafts having intermediate portions of square configuration and end portions of cylindrical configuration extending loosely through the apertures in the sides of the hopper and aforesaid plates, substantially semi-elliptical agitatorsloosely mounted on the shafts between the aforesaid plates so their free ends will extend above the upper edges of the plates throughout a certain degree of their arcuate movement, removable bearings secured to the outer surfaces of the sides of the hopper and'vsupporting the ends of the shafts, and driving means connected to those ends of the shafts disposed on one side of the hopper.
