" covering certain desired portions or elements of the material-content. One of its objects is the provision of an efficient apparatus of this character which is so designed as to provide a unitary structure includ- H ing a screening unit and a conveying means onto which the fines are deposited, and which is also designed for use in separating and reclaiming processes, whereby all or part of the material is conveyed to a predetermined discharge point.
Another object of the invention is to provide simple, reliable and eflicient meansfor imparting a positive gyratory movement to the screen frameas'well as a positive'f'e'ed to the conveying means.
Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.
In the accompanying drawings:
Figure 1 is a perspective view of the apparatus embodying my invention. Figure 2 is a central longitudinal section thereo Figure 3 is a side view of the apparatus showing the means for driving the conveyor from the main operating shaft of the machine. Figure 4 is a cross section taken substantially in the plane of line 44. Figure 2. Figure 5 is a central longitudinal section similar to Figure 2 showing a modification of the invention. Figure 6 is a perspective view of the conveyor shown in Figure 5.
Similar characters of reference indicate corresponding parts throughout the several views.
In the preferred embodiment of the invention shown in the drawings, the same consists of a gyrating body or live frame consisting of side plates Ii], l carrying a plurality of screen decks ll supported between the side plates. In the drawings, two of such screens are shown, the upper one being of a coarse mesh and the lower one of a fine mesh, Below the screening surfaces to receive the material passed through the same, is a conveyor which is by preference in the form of an endless belt l2 extending practically the full width of the space between the side plates and passing at its ends around drums l3 suitably journaled in bearings I 4 applied to the side plates. This screening and conveying unit or assembly is supported for a rotating or gyratory movement upon a suitable stationary frame structure l which may consist of I-beams, as shown, or may be of any other suitable construction.
1934, Serial No. 705,724
The live frame, including the screens II and conveyor [2, is balanced or supported for rotatingvibratory movement midway of its ends on a rotary transverse shaft l6 journaled at its ends in suitable bearings l1 supported on the main frame i5 and extending through the sidewalls or plates in of the live frame at substantially. its This shaft constitutes the arranged with housings l9 applied to the side plates it]. Mounted on the shaft l6 between the liveframe I0 and the supporting frame l5 are counter-balanced wheels 28. At one end, theoperating shaft is provided with a pulley 2| which may be connected by a belt, not shown, with an electric motor or other source of power.
Adjacent its opposite ends, the live frame is resiliently supported upon compression springs 22 or like elements which may be arranged within suitable housings 23 applied to the outer sides of the side plates l0 and which are seated at their lower ends on supporting bars 24 secured to the frame-beams l5, the springs being disposed in substantially an upright position to yieldingly sustain the ends of the live frame.
The conveyor belt I2 is driven at a comparatively slow speed from the operating shaft l6 of the machine preferably by the following means:
Applied to one end of the operating shaft I 6 is an eccentric pulley 25 which is so mounted thereon as to be in exact synchronism with the gyrations or oscillations of the screen-body and to this end an eccentric 25 is applied to said shaft about which the pulley is fitted. The bore of this pulley is of such eccentricity to its periphery that it exactly corresponds in magnitude and direction with the gyrating body actuating eccentric l8 of, the driving shaft. This pulley is connected by a crossed belt 26 with a somewhat larger pulley 27 mounted on a shaft 28 suitably journaled in a housing 29 mounted on brackets 30 secured to the outer side of the adjoining side plates ID of the machine. Arranged within this housing is a pinion 3| secured to the shaft 28 and meshing with a gear 32 fixed to a shaft 33 journaled substantially centrally of the housing. Said shaft 33 extends rearwardly through the housing 29 and fixed thereon is a pulley 34 about which one end of an endless belt 35 passes, the other end of the latter passing around a somewhat larger pulley 36 secured to a shaft 3'! projecting from the adjoining end of the conveyor drum l3. By this motion-transmitting means, the conveyor belt I2 is moved at a comparatively slow speed while the live frame of the machine bearing the conveyor and the screens II is gyrated at a comparatively high speed.
The belt 12 is preferably made of rubber or like material and its upper stretch between the drums I3 is supported on guide rolls 38.
In the modified form of the invention shown in Figures 5 and 6, the conveyor belt 39 is driven from the drive shaft l6 of the machine in the same manner as heretofore described. On its surface, however, it is provided with projecting ribs or riflles 40 which are substantially v-shaped and which function to catch or intercept and retain the heavier particles from the materials passed through the screens H, while the lighter particles pass downwardly from the gyrating of. the body l0 over the inclined moving belt into a suitable container provided for receiving them. The heavier particles move with the belt and are discharged at the opposite end of the belt, dropping therefrom by gravity into a suitable container provided therefor.
