IPERCY E. LONGr AND WILLIAM L. SCHWARZ, OF LA GROSSE, WISCONSIN.
SEED-SEPARATOR.
To all whom t may concern.'
Be it known that we, PERCY E. LONG and vWILLIAM L. SCHWARZ, citizens of the United States, residing at La Crosse, in the county of La Crosse and State of Wisconsin, have invented certain new and useful Improvements in Seed-Separators, of which the following is a specification.
The invention relates to gravity separators.
The object of the invention is to provide an inclined table divided into transverse spaced sections separated by transverse belts the upper runs of which receive and carry off those seeds which are less spherical and do not roll so readily down the inclined sectional table; also to provide inclined throw backs on t-he upper side of the inclined table at the edge adjacent to the delivery ends of the belts to throw back the seed that roll but which have been carried near the delivery side by the belts before reaching the next inclined table section below; also to provide means for readily raising and lowering the upper end of the table to properly adjust its inclination; also to provide an etlicientmeans for driving the several belts and imparting the proper tension thereto. These objects are accomplished by the construction shown in the accompanying drawing, in which:
Figure 1 is a perspective of the improved separator. Fig. 2 is a cross section of the machine through one of the belts. Fig. 3 is a like section through one of the table inclines. Fig. L is a detail view of one of the adjustable pulleys for the belts.
A designates uprights at the head end of the machine, and A shorter uprights at the lower end and these uprights are mounted on a suitable base A2, to which they are braced by rods A3.
B is the table formed of a rectangular frame having parallel side bars Z), b and end bars b, 2). The lower end of this frame is hinged to the upper ends of the lower uprights A', while the upper end of the frame is provided with a transverse shaft C, the
Specification of Letters Patent.

Serial No. 732,326.
i outer ends of which pass through two slides C', C, embracing the uprights A and sliding thereon. In the outer ends of the slides C, C are guide pulleys c, 0 running' on guides a secured to or formed on the adjacent sides of the uprights A, the opposite sides of which uprights are provided with racks a, a. The shaft C has pinions c', c at its ends, which pinions mesh with the racks af, a, so that by turning the shaft the head end of the table B may be raised or lowered to change the angle thereof.
The upper or working side of the adjustable table B is formed of a series of trans verse plates b2, preferably of metal anc spaced apart a distance to receive the upper runs of a series of transverse belts D which form the traveling sections of the table. The table surface is thus formed of alternating traveling and fixed sections. The upper edges of the belts D underlie the lower edges of the fixed plates or sections b2, while the lower -edges of the belts overlie the upper edges of the fixed sections. This construction causes the belts to have less pitch than the rest of the table surface.
One side of the table frame is provided with pulleys E, one for every belt and a d escription of one will suffice. The pulley E is provided with a shaft e, journaled in adjustable blocks e, mounted to slide in brackets E', E secured to the table frame b and these blocks e may be moved in or out to adjust the tension of the belt D by means of set-screws e2, as clearly shown in Fig. 4. The blocks e have depending bolts e3 e,\:- tending through slots et in brackets E and on the bolts are nuts e5 for securing the blocks e in their adjusted positions. At the opposite side of the table the belts pass around drive pulleys E2 mounted on short shafts E3. |The shafts E3. are journaled at their overlapping ends in double bearings E4, carrying grease cups es. The shafts E3 are provided with sprockets c7 connected by sprocket chains es.
Power is applied to the shafting by means of a drive pulley F mounted on a. shaft F' Cgi on the lower end of the table B and having a bevel gear f meshing with a bevel pinion el on the end of the lower shaft fi.
the fixed table sectionsI or plates b2 are prm'ided at their ends next to the delivery ends of the belts D with throw backs or deflectors fl inclined inwardly from their upper ends so as to throw back certain seeds inward the middle of the table. A hopper il is mounted on the head end of the table and this hopper may be fed from any suitable source, not shown.
It will he seen that were the belts D all driven by a single line shaft their upper runs would of necessity lie in the same plane, but by my construction the upper runs of the belts are made to lie in parallel planes, since their short drive shafts E2 are parallel and inclined longitudinally of the side of the table. This allows the stationary plates b2 to lie in the saine plane with their upper edges underlying the lower edges of the belts D and their lower edges overlying the upper edges of the belts. rlhe belts D, therefore, have less pitch than the stationary plates b2, with the result that the seeds of less round ness will. be stopped by the belts and carried olf, while the more perfect seed of the kind being treated will cross over the belts and roll freely across the plates b2 which have no depressions to impede their progress. These stationary plates b2 forni a perfectly flat table surface interrupted only by the belts D, the upper runs of which have, as before stated, less pitch than the fixed surface of the table. Moreover, were the fixed portions Z2 of the table given any depressions next to the lower edges of the belts D, it would require such an elevation of the head end of the table for the round seed to run down that the pitch of the belts would then be so great that the less rounded seeds would run thereacross and not be stopped and carried. off by the belts.
rihe operation is as follows: The table will first be set at the proper inclination or angle for the seed to be operated upon and the tension of the belts will also be adjusted. The belt driving gear will now be started and the seed allowed to flow from the hopper. flihould wheat be in the hopper mixed with oats, the wheat will roll by gravity down the table and cross over the belts and fixed sections to the lower end, but the Oats which do not roll so readily will stop when they reach the belts and so be carried off. Split peas and beans may be separated in like manner and so thistle and plantain from clover, and so on through many other varieties of seeds. in case certain seed, as wheat, are carried near the belt delivery side before rolling off, the throw backs G will keep them from rolling off that edge of the fixed plates and cause them to continue on down the table. Since the belts are more nearly horizontal than the fixed sections of the table, they will readily stop and carry olf those grains not so round as those. which readily roll down the table as a whole.
