, Leners Patent No. 107,860, dated october 4, 1 s7o.
"lMPRovl-:MENT |N GRAIN AND seen-CLEANERsi The Schedule i'efened to in these Letters Patent and making part of the same.
I,` NEWTON M. BowlingY of Knightstown, in the county of Henry :and State of' Indiana, have invented cert-ain Improvements in Graiu and SeedGlcauw ers, of` which4 the following is 't' specification.V
` V. Nature and 'Objectsoftlw Inrcnti'on,
Myinvcntion relatesto'thel onstrnction anclmo'dc of operating thescreenffram ,Eby which grain is sepf `arated.
l Also` to 'theV same, in combination witha fau for cleaning the grain from eha'iandfdust.
Also to the same, iu combination with `an endless canvas apron' for separating.;certain kinds oi grain trom others 1 1 y C 1 [Description of the Accmiqumying jDrawtng.
Figurell` is a side elevation of a machine in which my improvements'ai'e embodied. v
. Figure Eis a longitudinal[sectional elevation.
l GeneralDescription. The machine is s 1 B is the grain-hopper, having, at its Vdischarge-tuinening, anadjustable slide, a.. Y Another adjustable slide, a', below the niouth of the` hopper," is also provided-j C is .the fan, its' shaft prolonged through the side of the` machine,l amlfurnished with a pulley, b, which receives a beltc, fr`om pulleyd, on crank-shaft- D.
d is 4another,,pulleyon crankfshaft, having belt c,Y
vextendhig topulleyavhich will be presently referred to.` l l l E is a scrceniiaine, upportedA between the four posts, A A, in` a.position-yinclinedV slightly downward toward the rear. 3 i 'At therreai en d screen-frame rests upon a notched or serrated support, g, and has a surface of contact, gf, also notched in` a similar manner. lhe opposite or` front endjof screen-frame E rests upon anotched wheel,h, and it has a notch, h', appropriately formed, for Va purpesc which will 'beexplained. n g
The framei carries three screens or separators, i
t t, having separate functions, wliiclrwill be ex. l
plained. t
l.: is an open or` large-mesh screen, placed -at the `f ront ofthe machine.
12 3 45416 are drawers orrcceptacles for grain'and seeds, as they are separated.`
l is a canvas apromearried by 'drums 7n. m, theI latter having its shaft prolonged to receive pulley f, by
which` motion is ,communicated througl'belt-e, before u is a' spiral spring, one end of which is attached to screen-frame "E, andthe othel` topost A'.
1 upported upon four posts-two front posts, A, and two rear posts, A'.
`and falls into section 1.
'When motion' is communicated to crank-shaftl) the i'an C and canvas apron l are set in motion. At the same time the notches in wheel It, encountering .the notch It in the screenfframe E, impel the frame violently for a short distance in one direction, and, as l the notches escape, the springs a cause it to return suddenly and violently, imparting thereby a quick and violent tremulous motion to the screen-flame, reciprocatingfboth in the inclined plane and vertically thereto. Ast-he screen-frame rests at its rear end upon the notched support y, this end of thescrecn `also partakcs of the same violent lmotion by which the screens are made effective as separators through their entire length.
l lI will, 'uo\v describe the practical operation of the machine: l
Grain supplied to hopper B descends, through the rcgnlatedopening-at the.v bottonnto open screena,
where straw and other coarse matters are arrested;V
thence, de'scending,thc `grain is4 exposed to the blast from fan C, and falls upon upper screen i, the meshes of which `are so open that all` grass-seeds and small grains pass through. The large grains descend along on the screen, and discharge upon canvas apron l. Here any grains of oats or other grains having hulls surrounding them adherc'to the canvas, and are carried up and discharged over into receptacle 6,.while the-smooth grains descend and fall intoreceptacle 5;
` Themeshes of screen t" are so vlargethatall seeds of grass andweeds pass through, and only small and broken grains pass over and fall into receptacle 4. Screen fi" is composed of three sections of different mesh, and thearrangement is such that cheat and cockie passjovcr in todreceptacle 4; pure timothyseed, heilig somewhat finer, passes through ,the middle section,'and falls into receptacle 2 g while wirerrassseed 4 passes through the fine meshes of the rst section,
. Claims.
1. The screen-fraaie E carr in(r screens` if" in `combination with the notched support y g', wheel 7i,l
land notch h', and spring n., substantially as and `for .the purpose specified.
2. The screen-frame E and screens, when supported and operated in thc manner specified, in combina' tion with fan'- G, as and'fo'r the purpose described. 3. The screen-haine E and screens, when supported and operated in themauuer described, in combination with the canvas apron l, for the purpose specified.
