To all whom it may concern.-
Be it known that we, SAMUEL FRANKS, J r., DAVID FnANKs, and CHARLES- FRANKS, citizens of the United States, residing at Milin the countylof Holmes and State of Ohio, haveinventedcertain new and useful Improvements in Separators, of which the following is a specification.
This invention relates to an improvement in separators, and more particularly to the separation of grain andseeds, the object of the invention being to separate light or foul seeds and grit from the 00d or clean seeds,
this being accomplished y discharging the grain or seeds fromafhopper at intervals upon an endless belt,- which is supported at such anincline that the lighter or foul 'material will pass over the upper end of by a paw 1 .6. on the frame A. frame B'is'made in two sections and is adthe belt, and the good or clean seeds will pass down over the lower end of the belt into a hopper, where it can any suitable receptacle.
The invention consists of certain novel features of construction and combinations of .parts which will be described and pointed out in the claims.
In the accompanying drawings-Figure 1 is a view in side elevation; Fig. 2 is a. to plan view 5 Fig. 3 is a longitudinal vertica section; 4 1s a view of a brush for cleaning the en ess belt, and Fig. 5 i-sa detailed view disclosing the manner of connecting the endless belt. to the links of the sprocket chain. i
A represents a frame or support which may be used for supporting the separator frame B. I have shown theupper end of the frame B plvotally mounted as at 1 to the frame or support A. The lower end of the frame is ad ustably supported on the frame A by ropes 2,which are connected to the frame and to the shaft 3-,, which is journaled in the frame A. Connected to one end of the shaft 3is a crank arm 4 for adjnstin the inclination of the frame B. The sha by a ratchet 5 on the shaft which is engaged justably connected together by means of bolts 7, which lengthened or shortened as desired for regulating the length of the frame for tightening the endless belt C which is mounted on shafts 8 and 9 journaled in the frame B. Sprocket wheels 10 are mounted upon the -mitted to the shaft 9 for hereinafter more fully which is provided with shaft 9 is rotated the sprocket Wheel 20 is sha' 3 is held in its different positions The separatorpermits of the frame being shaft 9, and sprocket wheels 11 are mounted on the shaft 8 over which sprocket chains 12 pass, which chains are connected to the endlessbelt C by any suitable means whereby the belt is moved. Mounted on the shaft 9 isa belt pulley 13 whereby motion is transcausing the belt to'travel. A hopper 14 is mounted upon the separator frame B near the forward end of the belt C. An opening 15 is formed in" the bottom of the hopper for admitting the grain from the hopper topass onto the belt. An agitator or spreader shaft 16 is journaled in the hopper and is provided with blades 17;
' the bottom of the hopper. be conveyed to A pocket 17 is suported on the underside of the frame B,- and is adapted to receive the light seeds or foul material, grit, andthe like as it passes over the forward end of the belt in the separation of the grain. A screw conveyor 18 is journaled in the bottom of the pocket for discharging the material through the bottom of the pocket. A sprocket wheel 19 is journaled onone end of the screw'conveyer 18, and the sprocket wheel 20 is mounted on the shaft 9, and an idler sprocket 21 is adjustably'mounted in a slot 22 in one side of theframe B. Passing over these sprockets 19, 20, and 21 is a s rocket chain 23, ugs 24. As the rotated causing the sprocket chain 23 to move, thereby actuating the shaft 18 for discharging the contents of the pocket 17.
A rock shaft 25 is mounted on the hopper 14, and connected to the shaft. is a slide 26 by straps 27. The slide 26 is adapted to close the opening 15 formed in the bottom of the hop er 14. An arm 28 is connected to the 25, and the arm is operated by the lugs 24011 the sprocket chain 23. As one of the lugs 24 which are formed at certain intervals on the belt comes in contact with the arm 28 the arm will be operated, causing the shaft 25 to be rocked, thereby drawing the slide and permitting the grain to pass from the hopper through the opening 15 onto the belt 0 A spring 29 is connected to the arm 28 and 'to a bracket 30 and is adapted to draw the arm 28 rearward thereby causing the slide 26 to be moved for closing the pivotal y mounted on t openin 15 of the hopppr 14. A lever 31 is e hopper and at one end of the lever a pawl 32 is mounted, which is adapted to engage ratchet wheel 33 mounted on the spreader shaft 16. The lever 31 is operated by the engagement of the lugs 24 on the sprocket chain 23, and as the lug comes in contact with the lever drawing it forward, the pawl 32 is drawn rearward causing the spreader shaft 16 to be revolved. A spring 34, which is connected to the lever 31 and to the bracket 30, draws the lever rearward and the rearward movement of the lever causes the pawl 32 to be moved forward to take another hold upon the ratchet wheel 33 for the next operation. Anintermittent feed is provided as the lever 31, which is adapted to rotate the shaft 16 by the pawl 32 and ratchet wheel 33, is actuated by the lugs 24 on the sprocket chain 23, and the arm 28 is operated by the lugs 24 for causing the slide 26 to be drawn forward to permit the discharge of the grain from the hopper onto the belt. The lugs 24 are spaced sucha distance apart that the springs 29 and 34 will draw the arm 28 and lever 31 rearward to their normal position after their operation by the lugs 24 for the next operation, and the slide 26 will be moved for closing the opening in the hopper thereby preventing any grain from being admitted onto the belt C until the arm is again operated by the next lug on the sprocket chain 23. i
A pocket 35 is connected to the lower or rear end of the separator frame B, and journaled in the pocket is a screw conveyer 36 for discharging the good or clean seeds which are delivered from the belt G into the pocket out through the bottom of the pocket to any suitable receptacle. A sprocket wheel 37 is mounted, on the shaft 8 and a sprocket wheel 38 is mounted on the shaft 36, and the sprocket chain 39 passes over the sprocket wheels 37 and 38 for transmitting motion to the conveyer shaft 36 as the shaft 8 is rotated. A table 40 is mounted upon the frame B, over which'the endless belt C passes. Adjustably mounted in the pocket 17 on a bar 41 is a brush 42, which s adapted to clean the belt as it travels over the shaft 9.
The shaft 9 is rotated by motion being transmitted to the ulley 13 and the sprocket wheels on the sha ts 8 and 9 over which the sprocket chains 12 pass will cause the belt 0 to travel as the shaft 9 is rotated. The sprocket wheel 20 on the shaft 9 is caused to rotate thereby transmitting motion to the conveyer shaft 18 by the sprocket chain 23. The lugs 24 on sprocket chain 23 will actuate the arm 28 thereby rocking the shaft 25 and causing the slide 26 to be moved thereby admitting a certain quantity of grain to be discharged upon the belt. The lugs 24 will also operate the lever 32, causing the pawl 32 connected to the lever to operate the ratchet wheel 33 thereby rotating the spreader shaft 16 in the hopper 14. After the arm 28 has been operated by the lug 24 the spring 29 will cause the arm to be moved rearward thereby moving the slide 26 causing the opening 15 of the hopper 14 to be closed. The quantity of grain discharged upon the belt C will be moved by the belt traveling over the shafts 8 and 9. The inclination of the belt will cause the large clean seeds or grain to travel toward the rear end of the belt and into the pocket 35, from which it is discharged by the screw conveyer 36 which is operated by the s rocket chain 39 passing over sprocket whee s 37 and 38. The lighter or foul material will be drawn over the forward end of the belt C and into the pocket 17, from which it is discharged by the screw conveyer 18. Another quantlty of grain will now be admitted to the belt 0 from the hopper 14 by the actuation of the arm 28 and lever 34 by the lugs 24 on the sprocket chain 23. The lugs 24 are so arranged upon the sprocket chain 23 that they will not operate the arm 28 and lever 34 until thematerial which has been admitted from the hopper 14 to the belt C has been separated. The brush 42, which is su ported in the pocket 17 will keep the bet clean during the se arating operation.
