BEAN-SEPARATINGV MACHINE.
SPECIFICATION forming part of Letters Patent No. 741,956, dated October 20, 1903. Application led May 1,1903. Serial No. 155.159. (No model.)
To tZZ when@ it may concern:
Beit known that we, EDWARD BURNETT, JOHN F. TURNER, and JOHN C. OATMAN, citizens of the United States, residing at Clifford, in the county of Lapeer and State of Michigan, have invented certain new and useful Improvementsin Bean-Separating Machines, of which the following is a specification.
The invention herein is directed to the production of a machine for separating beans wherein the separation is eected by the ro-` tation of a cloth-covered roll, the function of which is to seize and carry the bad beans upward upon and over the roll from a stream of beans moving against and lengthwise of the roll, the surface of which for this purpose being formed of some suitable fabric that will seize or take hold of the bad beans and deliver them upward over the roll.
Y The following description read with the accompanying drawings will enable any one skilled in the art to whichour invention relates to understand its nature and to practice it in the form in which we prefer to employ it; but it will be understood that our invention is not limited to the precise form and details, of construction herein illustrated and de-` scribed, as various modifications and changes may be made without exceeding the scope of the claims in which our invention is set out.`
Referring to the drawings, Figure 1 represents a front elevation of a machine for separating beans embracingour invention,the`` parts for effecting the separation being shown by dotted lines. Fig. 2 is a vertical section taken transversely of the separating parts.` Fig. 3 is a top View of the same.
feed-roll enlarged.
Between the vertical sides of a suitable frame is mounted a roll 1, about thirty-three inches long and from tento sixteen inches in diameter and is inclined so that at one end lit is about three inches lower than the other.
It is covered by a suitable cloth of the desired roughness adapted to the kind and condition of the beans. A feed board or trough is formed along one side of the rolla suitable distance above its axis-line bya table or guide- Way 2and terminates a little beyond its lower end in a chute 3 at the side of the frame. The edge of this 'table is adjacent to or abuts lightly against the cloth surface of the roll, and it is supported in an upwardly-inclined position from the roll by a curved arm 4, depending from each end of the table and fastened to the inner wall of the frame by a thumb-screw 5, passing through a slot in said arm, whereby to allow of the adjustment of the table to give the trough moreor less inclination toward the lowest end of the roll to suit the speed of the roll and to give more or less speed to the stream of beans or to set -the table higher or lower in its relation` to the that it rotates in close proximity to the concave wall, with its upper part in the throat of the discharge-opening. It is important that this feed-roll be constructed to take the beans from the hopper and deliver them upon the table without cutting or bruising, and for this purpose We prefer to use a roll having longitudinal surface recesses, which as the roll is turned receive and feed the beans into the trough formed by the table and the roll. A roll two inches in diameter will give foursurface recesses which will provide a comparatively` thin continuous stream of beans down the trough, and this division of recesses will give four angular surface projections, each of which has a curved part 8, which forms the circumference of the roll, a iiat part 9, which forms the bottom of the recess, and a radial part 10, which joins the curved surface with the bottom of the recess, so that in the rotation of the roll the beans are caused to till the recesses and be delivered therefrom by an overshot feed. The feed of the beans from the hopper to the feedroll may be regulated by an adjustable slide 11, set on the wall of the hopper above the feed-roll.
We have shown a pair of cloth-covered rolls each having an adjustable table and a feed-roll, and separator-rolls arranged in the frame in the same horizontal line and driven by the same power-driven line-shaft 12, each roll having a pulley 13, driven by a band 14 from a'pulley l5 on the line-shaft. It is also obvious that a plurality of rolls of different sizes may be used in the same machine, all driven from the same line-shaft. There being a feed-roll for the trough of each separating-roll, a line-shaft 16 is mounted on the outside of the frame, carries each feed-roll, and is driven by a band 17 from a pulley-18 on the line-shaft which drives the separating-rolls, so that by having the pulleys on the lineshafts of the same size the speed of the separating-rolls and the speed of the feed-rolls may be the same or they may be different, as may be desired, to suit different qualities of beans. As each separating-roll has a discharge-chute, the good beans are delivered from each chute preferably into an inclined chute 19, connecting all the roll-chutes with a bin, or into a bag connected to the chute of each roll-trough, while the bad beans are delivered into a wide chute 20, depending from the frame beneath the rolls. The separation of the bad beans from the good beans is the fact that the roughness and irregularity of the bad beans will cause them to catch to the clothby reason of its roughness, and as the roll rotates much faster than the bad beans will turn over in moving down the tabletrough they will be carried up over the roll and fall into the bin, together with any dirt and small seeds or grain which may be gathered with the beans. Moreover, the movement of the roll gives a stirring action all along the stream of beans, turning them over, so thatthe rough roll-surface will pick out the rough bad beans from the stream and take them up on the tu-rning roll, and for this purpose the table or feed-board is set inclining upward away from the side of the roll in order that the stream of beans may be held and stirred against the cloth surface the length of the roll as it rotates, and it is during the sliding movement of the row of beans down the board and the action of the roll in stirring the beans during such sliding movement that the bad beans are picked from the stream by the roughness of the cloth and carried away from the stream by a movement at right angles to the direction of the movement of the stream. In effecting this sliding movement of the beans the feed-board must beinclined in the same direction as the roll in order to provide a regular and certain feed, while the vertical adjustment of the lfeedboard at both ends gives the advantage of setting it the saine or at a greater or less inclination than that of the roll and maintain its proper relation to the feed-hopper, to the delivering-chute, and to the top of the roll.
We claiml. In a machine for separating beans, the combination of a board inclined laterally and longitudinally, and a rotatable inclined clothcovered separating-roll in juxtaposed relation to the lower edge of said feed-boardand means for adjusting the feed-board at its receiving and at its delivering ends.

In a machine for separating beans, the combination of a hopper having a regulable discharge, a laterally and longitudinally inclined feed-board having its high end at the hopper-outlet, means for adjusting the inclination of said feed-board, and a rotatable inclined cloth-covered separating-roll in juxtaposed relation to the lower edge of said feedboard.
3. In a machine for separating beans, the combination of a hopper having a dischargeoutlet, a regulable gate at said outlet, a chute leading from the outlet, a longitudinallyribbed rotatable feed-roll in said chute, a laterally and longitudinally inclined feed-board onto which said chute delivers, and a rotatable inclined cloth-covered separating-roll in juxtaposedv relation to the lower edge of said feed-board.
