Sieves for Separators.
Patented March 25. 18.73,. Jgw.
UNITED STATES PATENT GEEICE.
IMPROVEMENT IN SIEVES FOR SEPARATORS.
Specification forming part of Letters Patent No. 137,145, dated March 25, 1873.
To all whom it may concern:
Beit known that we, BYRON MILLER and i MAJOR MILLER, of Lowell, in the county of Dodge and State of Wisconsin, have invented a new and Improved Sieve for Thrashing- Machines; and we do hereby declare that the y following is a full, clear, and exact desz'ription of the same, reference being had to the accompanying drawing forming a part of this specification, in which- Figure 1 is a top view, and Fig. 2 a vertical transverse section, of our improved sieve for thrashing-machines.
This invention ,relates to a new construction of sieves for thrashing-machines, and is an improvement upon the Church sieve patented June 27, 184:6.
The Church sieve has inclined plates running the whole length across the sieve, and set below the perpendicular plates. In usin g. this sieve at the present day, with machines that thrash a large amount per day of grain, of which more or less is generally damp, the short straw and chaff accumulate on the sieve and prevent its proper action as sifter. The dirt also is caught by the vertical plates, and either clogs the sieve orlgoes into the measure with the grain. The inclined plates, be-
ing aligned, are also found to allow fine leaves and straw-to double over the perpendicular plates and lodge on an inclined plate.
Our invention therefore consists in constructing the sieve so that the tops ofthe perpendicular and inclined plates are brought into the saine plane, while the inclined plates areshort, and the adjacent ones in different planes.
A in the drawing represents a frame, and B a sieve. a a are long perpendicular plates of sheet metal, parallel to each other, and b b short plates, placed in different pla-nes, and
transversely thereto, the tops of plates a and b being all in the same plane. y
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
A thrashing-machine sieve, having the inclined plates b short, the adjacent ones in dit'- fercnt planes, and all with their tops in the same plane with the tops of the perpendicular plates a, as and for the purpose described.
