PATENT, OFFEQE IOWA oA'r HULLER 7 Application filed January 8,
The object of our invention is to providean oat huller of simple, durable and inexpensive construction, which is reliable and positive oats, which is rapid in its-operation and atr the same time adaptedto' perform its work 2 our improved oat huller,
I huller element,
without clogging or tangling. H
Our invention consists in the construction, arrangement andcombination of the various parts of the device, whereby the objects conteniplated are attained, as hereinafter more fully set forth, pointed out in our claims,
and illustrated in the'accompanying drawings, in which:
' Figure 1 is a longitudinal sectionalview of v Figure 2 is atransv erse sectional view taken on the line 2--2 of Figure 1,
Figure 3 is a front view of the rotating Figure 4c is an end elevation of same. The nun1eral10 indicates'acylindrical casing, one end of which communicates with a separating device, such as ordinarily used in oathullers and which forms no partof our present invention. The other-end of the casthe lower end of a hopper 13. One side of the hopper 13 is. provided with a bearing ll for,
j hub being rigidly secured to the shaft 15.
. outwardly extending and radial blades 20 ing is provided with a wall 11 having a central opening provided with an inwardly proj ecting collar 12. Said collar is connected to rotatively, receiving a shaft 15 located centrallyand longitudinally within the collar 12, and has its outer end provided'with a driving The inner end of the shaft 15 designed to support the huller element 17 which 'comprises a disk 18 supportedby a hub 19, said The periphery of the disk 18 has a series of mountedinplanes parallelwith the shaft15. The front edges of the inner ends. of the blades 20 are connected bymeans of an annular blade 21 which strengthens and supports the blades" 20. The forward edgesof the blades 20'are bent to form flanges 22, said provided with a circumferential projection between the plate 18 and the said collar.
,hulled grain will be delivered outwardly to the sides of the casing 10 by centrifugal force 1929. Serial ITO/331,075. f
advancing edges of said plates. are bent forwardly to "engage the forward edge of the back face of the adjacent plate 23, so that the peripheral edges of the plates 23 are of helical formation, so that grain engagedby. the peripheral edges of said plates will be thrown rearwardly in the casing.
The outer end of the back edge of each of the blades .20 is provided with rearwardly projecting flange 24, having its lower edge 25 extending in the direction of rotation of the huller element. The impeller is mount- 1 .ed on the shaft 15 in such a manner that the collar 12 enters the plate 21 and terminates By this arrangement it will be seen that if the hopper 18 is filled with oats or similar grain to be hulled, and the shaft 15 is rapidly rotated, then the huller element will also be rotated in acount-erclockwise direction, as viewed in Figure 2, then oats will be delivered through the collar 12 and will fall downwardly into the path of the rotating blades 20, and the oats engaged bysaid blades before ithas reached the bottom of the casing 10. The velocity of the blades 20 is such that a" large per cent of the grain will be 'hulled by the impact between said grain andlsaid blades. f The kernels and'hulls and the unand will engage said casing with a considerable force which will hull the grain not previously hulled. A large portion of the grain will rebound and be delivered toward the center of the huller element, and be engaged by the front surface of the members 24. The
well as prevent' the grain from moving inwardly too rapidly, :which will again be thrown outwardly over the peripheral edges of the members 24 and be engaged by a preceding blade 24. j 7
The back surface of the helicalplates 23 assist in advancing thematerial longitudi- 100 i be rigid and engage'the grain without v1- brating. The success of devices of this kind nally Within the casing 10 and this causes the material to be delivered rapidly through the huller.
One of the advantages of our devi-ce lies in the fact that the huller element is formed of a unitary element in which noobstructing angles or openings are included, so that any straw or other foreign material entering the feedcollar 12 will be delivered to the huller element "and carried therethrough without winding or tangling. This is a very important point inasmuch as heretofore great diffi cul-ty has been experienced with various types of hullers in which the huller element clogs and causes a greatdeal of troubleand delay.
The helical plates 23 not only assist in advancing the material rearwardly in the huller casing, but also greatly assist in reinforcing and strengthening the plates 20'. This is also very essential as it is necessary that the plates "depends largely upon administering an I abrupt and positiveblow to the grain hulls,
which causes them to open by the sudden strain imparted. thereto.
It will therefore be seen that we have provided an oat huller of simple, durable and inexpensiveconstruction, which :is capable of rapid and positive hulling oflarge quantities a of grain withouttangling or clogging.
