SAMUEL A. JESKE, OF JAMESTOWN, NORTH DAKOTA.
GRAIN-SEPARATOR.
Specification of Letters Patent.
Patented nne 11, 1918.
Application filed February 26, 1917. Serial N 0. 151,039.
To all whom it may concern Be it known that I, SAMUEL A. JnsKn, a citizen of the United States, residing at Jamestown, in the county of Stutsman and State of North Dakota, have invented certain new and useful Improvements in Grain- Separators, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to certain improvements in grain separators and it is an object of the invention to provide a device of this general character having novel and improved means whereby cockle or other no);- ious seeds are separated from the grain.
It is also an obj cot of the invention to provide a novel and improved device of this general character including a plurality of screening elements arranged in stepped relation and wherein each of said elements is provided with longitudinally disposed runways, each of said runways having openings in a side thereof discharging upon an imperforate portion of a screening element directly therebeneath.
The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved separator whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.
The novel features of the invention will hereinafter be definitely claimed.
In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in top plan of a separator constructed in accordance with an embodiment of my invention;
Fig. 2 is a longitudinal vertical sectional view taken through Fig. 1; and
Fig. 3 is a sectional view taken substantially on the line 83 of Fig. 2.
As disclosed in the accompanying drawings, F denotes a frame ofpredetermined dimensions and with which are engaged a plurality of screening elements S, said screening elements being arranged in stepped relation. While I disclose only three of the screening elements in the accompanying drawings, it is to be understood that these elements may be of any number preferred.
In p notice I have found that best results can be obtained by having these screening elements about twenty in number.
Each of the screening elements S is provided with the corrugations 1 disposed lonsubstantially one-eighth of an inch deep.
One side of each of the corrugations 1 is provided for a predetermined distance intermediate the length thereof with aplurality of longitudinally spaced openings 2 substantially ovoid in form with the major diameter of each of said openings arranged transversely of the wall and with the narrow portion of each of said openings adja cent the low point of the corrugation. The openings 2 are spaced apart a distance less than the width of said openings and it is also to be preferred that the openings of a section be arranged in corresponding sides of the corrugations and that the remaining sides of the corrugations be imperforate.
It will be noted from Fig. 2 that the top screening element has the openings in its corrugations disposed adjacent the rear or receiving end of the screening element and that the next screening element has the openings in its corrugations disposed beneath an imperforate portion of the upper screening element, and forward of the perforations in the uppermost screening element, and that the lowermost screening element has its openings disposed in advance of the openings in the screening element immediately above and beneath the imperforate portion of the screening element immediately above, and that the screening elements are arranged in stepped relation, so that the seed and grain which may be discharged through the openings of the uppermost screening element will fall down onto an imperforate portion of the screening element just below, while the grain which has not passed through the openings of the upper screening element is carried forward and discharged onto the imperforate portion of the screening element just below and in advance of the openings. Thus as the grain and cookie seeds mixed therewith pass along the perforated portion of the uppermost screening element, the cookie seeds and some of the grain will drop onto the second screening element. Then as this material passes on by the perforated portions of this second screening element, the cockle seeds and some of the grain will be discharged through the perforations onto the screening element next below and that eventually all of the'cockle seeds will be separated from the grain and the grain Will be discharged out the forward end of the separator. The grain is elongated in form and reciprocative motion transmitted to the separator tends to shift this grain so that it lies parallel to the length of the corrugations and inasmuch as the perforations 2 are less in Width than the length of the grain, the grain will not pass through these corrugations, but will ordinarily pass forward and be discharged at the forward end of the screen onto the imperforate portion of the next succeeding screen. Some of the grain, however, is likely at first not to be arranged in a longitudinal direction and this grain, along with the cockle seeds will pass onto the second screening element. Those grains which become arranged with their longer axes parallel to the length of the corrugations will pass along the whole extent of the screen, but those grains which are not so disposed will drop with the cockle seeds through the perforations of this particular screening element and fall down onto the perforations of the next succeeding screening elements. Thus eventually all of the cockle seeds will be separated from the grain and the grain be thoroughly cleaned.
In practice my improved separator is adapted to be suitably mounted for vibratory movement and arranged substantially horizontal.
The manner in which the vibratory movement may be imparted to my improved separator forms no part of my present invention and for which reason a detail description or illustration of such operating means is believed to be unnecessary.
My improved separator is especially adapted for use in connection with grain such as wheat, oats, barley, rye, or the like and for the purpose of separating therefrom cockle or other noxious weeds. The grain before referred to is of an elongated character and it will be at once noted that as the same travels along the corrugations 1 of the screening elements they will pass over the openings 2 while the cockle or other noxious seed which are substantially spherical in form will readily drop through said openings. By this arrangement it will therefore be obvious that after the grain has passed over all of the screening elements the seed will be thoroughly separated from the grain.
From the foregoing description, it is thought to be obvious that a separator con structed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modiiication without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.
1 claim:
A grain separator comprising a plurality of screening elements arranged in stepped relation, each of said elements comprising a sheet of metal longitudinally corrugated, the corrugations being open at their dis charge ends, a side wall of each of the corrugations being provided with a longitudinally extending series of perforations, said perforations being substantially oval in form, the longer axes of the perforations extending vertically, the perforate portions of one screening element discharging upon an imperforate portion of the screening element immediately beneath and in advance of the perforate portions of said second element, each of said screening elements having an imperforate portion extending over the perforate portion of the screening element imi'nediately beneath and discharging downward onto said second named screening element at a point beyond the perforate portions of said second named screening element.
In testimony whereof I hereunto ailix my signature in the presence of two witnesses.
