To aZZ whom, it may concern:

Be it'known that we, WILLIAM F. BILL- MORE and DAVID Annnsnemcitizens ofv the United States, residing at Westernville, in'the county of Oneida and State of New York, have invented a new and useful Pea-Hulling Machine, of which the following is a specification.

This invention relates to pea-hulling machines.

The object of the invention is to provide a machine which will in a thorough, feasible, practical, and expeditious manner effect hulling of the peas from the pods and the separation therefrom of, the halm and vinesi To effect this result, weprovide. a plurality of beater-drums disposed equidistantly around an ideal common axis, said beater-drums being provided with ribs which are so inclined as to impart propulsion of the material from end to end of the space inclosed by said drums, the latter being in turn surrounded by a perforated drum orcylinder having lifting-ribs which cooperate with the beater-drums to propel, thresh, agitate, and separate the material operated upon. WVe also provide a feed opening or hopper in alinement with thespace between the receiving ends of the beaten drums. I M

A further object of our invention is to extend the beater-drums at the discharge end beyond the inclosing cylinder to avoid entanglement of the vines and balm discharged from the machine with the operating parts thereof.

With these and other objects in view, as will appear as the nature of the invention is .better understood, the same consists in the novel construction and combination of parts of a pea-hulling machine, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate corresponding parts, there is illustrated one form'of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may tical longitudinal section through a machine embodying the essential features of the present invention. Fig; 2 is a view in transverse section thereof, taken on the line 2 2, Fig. 1, and looking in the direction of the arrow thereon.

Referring to the drawings, 1 designates generally the supporting-frame of the apparatus, which may be constructed in any preferred manner, preferably of wooden beams, such drum is circular in cross-section but it is to Y be understood that, if preferred, it may be polygonal, and as this is common in structures of this character detailed illustration thereof is deemed unnecessary. Projecting inward from the-inner side of the drumis a series of longitud'inally-disposed vine-elevating ribs 5, the number of the said ribs being determined by the diameter of the drum and by the character of the vines to be operated upon. As herein shown, the ribs are associated with the cylinder by bolts or screws 6, which pass through exteriorly-disposed battens 7; but it is to be understood that no stress is to be laid to the particular manner of assembling the ribs with the cylinder, as various other ways of accomplishing this result may be adopted and still be within the scope of the invention. The drum is driven in any preferred manner, preferably bya belt (not shown) passing around one end thereof.

Arranged within the drum and projecting at the discharge end thereof, some distance therebeyond is a series of beater-drums 8 8 8 in this instance three-the axes of which are arranged on a line concentric with the drum 3, these beater-drums forming a circuit about the inner periphery of the outer or separating drum and being substantially equidistant therefrom and from each other. They cylinders. I the material slowly or evenly, inasmuch as; as soon as a bunch of the vines enters the are all driven in the same direction as the outer drum and in any preferred manner, preferably through the medium of bandwheels 9, carried by the outer ends of the shafts 10 of the said drums, the shafts being journaled in suitable bearin gs in cross-pieces at each end of the frame. The bodies of these drums may be constructed of any suitable material and are secured in any preferred manner to heads 11, keyed or otherwise attached to the shafts 10. To the outer side of each of the beater-drums is affiXed a series of beater-arms 12, which are'by preference disposed at an angle with relation to the drumshafts and overlap at an intermediate portion of the drum, as clearly shown in Fig. 1.

13 designates a feed-chute which is disposed at the feed end of the drum, where it is suitably connected with the frame in such a position that the vines fed to the machine shall be fed .into the space between the beaterdrums. A trough or receptacle 14: is suitably disposed beneath the outer drum for the reception'of the shelled peas which pass from the drum 3, from which said peas may be suitably fed to a place of deposit.

In practice the outer drumand the beaterdrums are all driven'in the same direction, as will be found indicated by arrows or darts upon Fig. 2 of the drawings, said beaterdrums .being rotated at a relatively high rate of speed, as shown by the heavy darts.

The operation of the device is as follows: The pea-vines are fed into the chute or hopper 14, passing from thence into the space between the rapidly-rotatin g beater drums or No care need be taken to feed space between the beater-drumsit will be violentiy torn asunder and subjected to thethreshing action of the heaters. When, as in the present instance, three beater-drums are used, the material fed between said drums will be forced. by the action of each drum in an outward direction'toward the outer drum. A portion of the vines will pass into contact with said outer drum. The greater proporwith the inside of the outer drum will be ole-- vated by the ribs of the latter until it reaches a point even with or slightly above the drum 8. .The tendency of the vines will be to drop upon said drum, and the tendency of the beaters upon the latter will be to carry the vines 'into the central space between the drums. The tendency of the boaters upon the second drum 8 to seize the vines and throw them outward against the inner wall of the outer drum will be counteracted by the heaters upon the third drum 8", the tendency ofwhich will be to throw the vines toward the first drum 8. It will thus be seen that the vines and pods by the combined action of the several drums will be violently threshed and agitated and that the tendency of the combined action of the three inner drums will be to retain the vines or halm between the said drums. It is not intended thereby to assert that the vines, pods, &c., are retained entirely in the space between the said beater-drums; but by far the larger proportion is thus retained and will be progressively fed toward the discharge end of the machine, while the smaller and especially the heavier particles, including necessarily the shelled peas, will escape to the outer drum, through the perforations of which they passinto the receiving-trough. Thus while the agitation to which the pea-vines is subjected is excessive from a standpoint of rapidity of action the beating they receive does not result in any damage, such as a bruising or mashing of the peas, they being protected by the halm, from which they are readily separated and permitted to pass to the outer drum. The disposition of the'ends of the beater-drum with relation to the outer drum-r1. e.,their being projected beyond the outer drumoperates to prevent entanglement of the vines 'with parts of the machine.

It is preferred'thatthe perforated shell of the outer drumbe madeup in sections, by which arrangement should one or more become damaged or worn out ready repair may be accomplished.

While the machine of thisinventionis exceedingly simple of construction,-it will be found thoroughly efiicientand durable in use and will, with the output of the minimum of power, accomplish the maxi-mumof work.

' jThe-precise construction of the different parts of the apparatus herein shown is not defined, being immaterial, the-broad underlying principle of the invention beingrapid agitation and beating of the pea-vines bysubjection tothe action of an outer rotary drum and a plurality of inner rotary drums.

Another and very essential distinguishing feature of our-invention consists in the disposition within an outer drumof aplurality of beater-drums so disposed relatively to each other as to form a central space into which the vines are fed and wherein they are mainly retained during their passage through the machine, the said beater-drums being rotated at a relatively high rate of speed in the direction of rotation of the outer drum, the latter thus cooperating withthe beater drums to elevate and to convey into thespace'between the latter such portions of vines and halm as will from time to time pass to the inner space of the said outer drum.

the same direction as the separating-drum and distributed about its central or axial space, inclined or riffled ribs-upon the said beater-drums, vine-lifting ribs upon the inside of the separating-drum, and means for feeding the vines into the central space between the beater-drums; which constitutes a conveyor-channel through which the vines mainly travel during their passage through the machine.

2. In a machine for hulling green peas from the vines, the combination of an external drum adapted to revolve and to elevate the material, a plurality of interior beating-and conducting drums arranged inside thereof equidistantly from each other around the axial line of the outside drum and forming a central beating and conducting passage for the vines.

3. A machine for hulling green peas from the vines, comprising a separating-drum supported revolubly and presenting an unobstructed interior, a plurality of beater-drums disposed longitudinally within and rotated in the same direction as the separating-drum and distributed about its center or axial space, said beater-drums being arranged to project beyond the delivery end of the outer drum, inclined or riffled ribs upon said beater-drums, vine-lifting ribs u ponthe inside of the separating-drum,and means for feeding the vines into the central space between the beater-drums, which constitutes a conveyor-channel through which the vines mainly travel during their passage through the machine.

In testimony that We claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
