HULLlNG-MACHINE.

SPECIFICATION forming part of Letters 'Patent No. 746,881, dated December 15, 1903.

Application filed April 14, 1902. Serial No. 1025863. (No model.)

To (LZZ- whom, it concern:

Be it known that I, FRED N. ROOT, a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and -State of Michigan, have invented certain new and useful Improvements in Hulling-llachines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention has reference generally to an improved type of mechanism for hulling peas, beans, or like seeds; and it consists in the novel construction of said mechanism whereby the hulls may be rapidly and effectively removed from the kernels in a minimum space of time.

The invention further consists in the peculiar arrangement and combination of the va rions parts of the hulling mechanism, as will be more fully hereinafter described, and shown in the drawings, in which- Figure l is a side elevation of the hullingmachine, partly-in section. Fig. 2 is a section taken on line 2 2 of Fig. l. Fig. 3 is a plan view, and Fig. 4 is a sectional perspective view, of one of the movable members.

In the drawings thus briefly described the reference-letter A designates the base-section of the machine. 'B B are standards thereon at the opposite -ends of the base, upon which is mounted the main operating-shaft C, journaled for rotary movement in bearings UCC C" designates means in the form of drivepllilleys for imparting rotary movement to the s a t.

The letter D represents one of the movable hulling members of my improved machine, between which and the complementary movable member K/ the kernels are adapted to be fed, the hulls being separated from the kernels during their passage between the members, as hereinafter set forth'. In construction the member D is in the formpof a disk fixed to the main shaft, as shown, and having a rubbing-surface D', consisting of, preferably, a layer of rubber or felt upon one of its faces.

The complementary movable member referred to I have shown in the form of an endless carrier extending in operative relation to the rubbing-surface upon the disk. The carrier is adapted to feed the kernels uniformly and comprises a belt K, which may be an ordinarycanvas belt, passing over a roller E at one end and rollers I' I' at the opposite end. These latter rollers, as shown, are mounted upon horizontal shafts I I, arranged one above the other in adjacence to the disk and mounted in suitable bearings upon standards -H upon the base.

J designates a trough mounted upon standards M upon the base, through which the upper portion ofthe carrier K passes, as plainly shown in Fig. 1. The trough extends at one end in close proximity to the rollers l/ I and at its opposite end is provided with a hopper J', through which the kernels are fed to the carrier.

Motion is im parted to the carrier through the agencyof the shaft E, journaled in bearings F' upon standards F, a bevel gear-wheel G upon said shaft, and a gear-pinion G upon ythe main operating-shaft O,the driving mechanism described being adapted to operate the carrier at a less speed than the disk.

In operation the beans or other kernels that are to be hulled are first soaked,so as to loosen the hulls, and are then fed through the hopper onto the carrier. From thence they pass betweenvthe end of the carrier described and the rubbing-surface upon the disk. Y It will be obvious from the construction of the in echanism as set forth that in addition to the rubbing the. kernels will receive due to the nnequalA velocities at which the two movable members are moving a twisting movement will also be produced due to the fact that the rubbing-surface upon the disk travels at different velocities at dierent distances from its axis of movement. The hulls are therefore rapidly and effectively removed from the kernels and are discharged from between the complementary surfaces into a spout J. The separation of the hulls from the kernels maybe subsequently effected by any suitable mechanism. As there is a tendency for the hulls to adhere to the surfaces ofthe movable members, I may and preferably do ein ploy means for keeping said surfaces cleansed. I preferably accomplish this l by discharging water within the trough J through the pipe L, controlled by a suitable valve L. The

Y. essary that both of the members should be movable. This will be readily apparent from the construction of the mechanism asset forth.

What I claim as my invention isl. In a hulling-machine, the combination with two complementary hulling members, comprising a rotary disk, and an elongated endless-belt carrier extending transversely to the disk, of rollers bearing against the inner surface of the t'op and bottom of the end of the belt adjacent the disk for guiding the said end portion of the belt across the surface of the face of the disk.

2. In a hulling-machine, the combination with two complementary hulling members, comprising a vertically-rotating disk, and an endless belt extending transversely to the disk, of means for operating the members, and means contacting the inner surface of the belt for guiding a portion of the outer surface thereof across the face of the rotary disk.

In testimony whereof I affix my signature in presence 'of two witnesses.

FRED N. ROOT.
