CLOVER4- HULLER.

SPECIFCATION forming part of Letters Patent No. 265,111, dated September 26, 1882.

Application filed May, 1882. (No model.) l

To all 'whom it may concern:

Be it known that I, DAVID LIPPY, of Mansfield, in the County of Richland and State of Ohio, have invented a new and useful Improvementin Clover-Hullers, ot' which the following is a specification, reference being nad to the accompanyin g drawings.

The invention relates to an improvement in clover-hullers; and its nature and objects will 'ne pointed out in the detailed description hereinafter presented, reference being had to the acconpanying drawings, in which- Figure 1 is a central vertical longitudinal section of a machine enbodying the elements of the invention. Fig. 2 is a detached view of the separator-frame E, and Fig. 3 is a detached top view of the troughs M and P and connections.

In the drawings, AB indicate the two sides ofthe machine, and 0 the trough* through which the clover is t'ed to the machine. The trough has a concave floor, and is supplied with a thrashing or stemming cylinder, D, and has its outlet at the front end of the agitating-frane E, which consists of the longitudinally-reciprocating bars a and the rocking bars b, the latter bars being arranged alternately with the The bars a are provided upon their upper sides at their front portions with the spikes or pickers c, and at their rear ends with the ratchet-teeth d, which may be cnt in the bars a or in separate bars to be applied to the bars a. The bars a are arrangedparallel with each other, and are mounted on the cross-bars e, the forward cross-bar being Secured upon the crank-axle f and the rear cross-barbeing supported by the swingingbars, whereby when the machine is in operation the bars a have a simultaneous reciprocating movement. Upon one end of the crank-axle f isa band-wheel, h, to which is eccentrically secured the front end of the connecting-rod i, the rear end ot' which is pivoted on one arin of the bell-crank lever F, Secured upona block adjacent to the rear of the machine., ln the other arm of the bell-crank lever F is pivoted one end of the rod H, the other end of which is secured to the bar I, connecting the crank ends of the pins J upon which the rear portions of the rocking bars b are pivotally secured. The front ends of the bars b are also mounted upon pins or small rods ot' appropriate strength. Upon the upper surface of the bars b are provided the pickers or inclined rods K, which add to the efi'ectiveness of the machine in hulling clover. 'When' the clover is fed unon the agitating-frame E t'romthe trough O the crankaxle f imparts to the bars co their reciproeating motion and causes the connecting-rod t' to give the bell-crank lever Fan oscillating movement on its pivot, whereby notionis communicated through the rod H, bar I, and crankpins J to give the bars I) a rocking motio. Thus the bars a and bars b havea simultaneous movement, the eft'ect being to thoroughly agitate the grain, separating the 'pods from the straw, the pods falling through the notches cut in the sides of the bars b to and upon the swingi ing board L and being conveyed by the same to the trongh M, while the straw and other ret'use will Work over the rear end of the agitatingframe and escape from the machine. The

trough M is seni-cylindrical in form, and isperforated upon its rear side and floor, and has centrallymounted in it the shaft N,which has upon its rght-hand end the fan or scraper m,

and extending froni said end to the left of the enconpassing the shat't and having two hlades V extending outward therefrom. In the front side of the trough M, directly opposite to the scraper m, is provided a door, n, leading to the hopper P,which is directly below the feedtrongh C, though having no connection therewith. The hopper P is of appropriate size, and will preferably have a con'cave floor provided with spikes or projections t, extending across it from one side of the machine to the other. Gentrally within the hopperPisnjounted the cylinder E, having over its surface the series of spikes or pickers S. Upon the left- 'hand end of the cylinder R, opposite to the door n, are the radial blades u, as shown, and upon the rear of the hopper is Secured the blade w, extending over the door n, as indicated in the drawing s. At the right-hand end of the hopper P, upon its front side, is provided the door w, having an adjustable slide,

too

w', whereby the size of the door and the volune of grain passing through it may be regulatcd at will.

Below and to the front of the hopperP and trongh C is the board T, which inclines downward over the front edge of the screen A', be.- low which are the boards B', inclining downward toward the center of the machine and terminatin g in the discharge tron gh orspout C'.

A fan, D of suitable Construction, is supplied at the front ot' the machine,wherebythe ehaff may be blown away during the operation.

Adjacent to the doora: is provided a hinged board, E', adapted to be adjusted at an augle thereto, and the purpose of which is to cast the hulled seed (as itis thrown out of the hopper P by the velocity of the cyliuder R) away from the door x and toward the center of the machine. When the pods or bolls leave the board L and enter thetrough M any clean seed that may be therein will fall through its perp forated bottom, while the pods or hulls and partly-cleaned seed will be carried to the lefthand end of the trough by the spiral shaft N, and is then scraped or knocked through the door 'n into the hopper P by the wings of the scraper m. After the grain enters the hopper P it is moved toward the right of the machine again bythe cylinder R and blades u w, and ou its passage to the right it is thoroughly agitated, and the pods broken and the seed hulled by the pickers S. The pods, seeds,&c., are driven from the hopper by the velocity of the cylinderR through the door w and fall upon the board T, whence they pass 'to the screen A' and are cleaned, the chafi'and other light matter being blown out through the rear of the machine, while the seed falls through the screen upon the boards B', and is conveyed away by means of the spout G'. The tailings will be returned to the hopper P in the usual manner.

-` It will be observed that the pods, Ste., enter the hopper P at one end, and are discharged theret'rom at the opposite end. During their passage from one end to the other of the hopper they are effectually broken and the seed hulled.

The employment of the eurved blades u upon the eylinder R is especially advantageous in that they keep the pods, &ci moving from the inlet-door n, and prevent the clogging of the machine. The movement of the clover pods or bolls from the inlet-door n is accelerated by the blade w, which prevents the seeds, &c., falling back over the cylinder in the same position they were in before. The blade w, being curved, acts to direct the grain toward the opposite end of the machine.

I do not limit myself to the exact Construction I have described, as the same may be modified in many respects without departing from the essence of the invention. i

What I claim as new, and desire to secure by Letters Patent, is 4 1. In a elover -hnller, the agitatingframe composed of the alternatinglongitudinally-reciprocating bars a and the laterally rocking bars I), substantially as set forth.

2. In a clover-huller, the agitating-f'ame conposed of the alteruating longitudinally-reciprocating bars a and the laterally-rocking bars b, having spacenotches cut upon their sides, and the erank-pins J and bar I for the purpose of giving the bars I a simultaneous rocking movement, substantially as set forth.

.3. In a clover-huller, the eombination of the trough M, having an outlet at oue end, means for conveying the graiu to that end and driving it through the outlet, the hopper P, and mechanism for moving the seed therein in au opposite direction to its movement in the trou gh M and hullingit, substantially as set forth.

4. In 'a clover-huller, the combination ofthe trongh M, having an outlet at one end, the spiral shaft N and scraper m, the hopper P, and the hulling-cylinder R, provided with the blades u on its end opposite to the inlet to the hopper, the outlet for the grain being at the opposite end of the hopper, substantiall y as set forth.

5. In a clove'rhuller, the agitatingf'rane, the trough M, having a perforated bottom, au outlet at one end, and means for carrying the g-ain to said end and driving it through the outlet, in eombiuation with the hopper P and the hulling-cylinder R, substantially as set forth.

6. In a clover-huller, the hopper P, having an inlet at one end and an outlet at the other, in combination with the blade 'w and the hulliug-cylinder E, provided adjacent to the inlet with' the blades u, and in combination with the blade w, substantially as set forth. I In testimony that I claim the foregoiug improvement in clover-h ullers as above described I have hereunto set my hand this 23d day of March, 1882.

DAVID LIPPY.
