GRAIN-SEPARATOR.

SPECIFICATION forming part ofLetters Patent No. 320,358, dated June 16, 1885.

Application filed March 25, 1885. (No model.)

To all whom it may concern Be it known that I, EDWARD HUBER, a citizen of the United States, and a resident ot Marion, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Grain-Separators; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same. reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a longitudinal vertical sectional view of a thrashing-machine equipped with my improvements 5 and Fi g'. 2 is a plan view of the bottom of the same,which is the subject of my improvements.

The saine letters refer to the same parts in both the figures.

This invention relates to thrashin g-lnachines or grain-separators and it has particular rei'- erence to certain improvements in the construction of the oscillating bottom and the part of the same overhanging the shoe, the

Aobjects of the said improvements being to ef- 'ect a more thorough separation of the grain from the chaff and straw.

The invention consists in the details of construction and arrangement which will be hereinafter fully described,and particularly pointed out in the claims.

In the drawings hereto annexed,A designates the frame of the machine, B the strawcarrier, and C the shoe, all of which are constructed in the usual manner, and in which no noveltyT is herein claimed.

D designates the oscillating bottom, which is mounted in suitable hangers and arranged to be oscillated by any suitable mechanism. Said bottom consists of a solid or imperforate front part, E,the rear end of which overhangs or extends over the front end of the shoe. Said part E is provided with a series of longitudinal ratchet-bars, F F, increasing in height from the front toward the rear end and extending slightly over the tail end G of the bottom, which is hinged to the part E, as shown, and which is likewise supported by suitable hangers. Ihe tail end or part G of the bottom consists of a board, which is provided for thc greater portion of its length with inverted funnel-shaped perforations H H, its rear end only being left solid or iinperforate. The upper side of the bottom board, G, is provided with longitudinal ratchet-bars I I, increasing in height toward the rear end, and terminating in arms J J, which extend over the tailings-spout K. The under side ofthe perforated portion of the bottoni board, G, is provided with one or more transverse forwardly-inclined dcflcctors L L, the function of which is to intercept the blast and cause it to act more effectively' upon the material passing over the bottom. The board Gis, of course, directly above the riddle M, upon Which the grain falls through the openings H H.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this inven tion will be readily understood. The ends of the rack-bars F will dump the grain and chai' from the bottom E onto the hinged perforated part G, where it is immediately exposed tothe blast. The imperforate rear end of the bottom board, G, prevents straw and chaff from ruiming into the riddle below, thus keeping the latter free from clogging. This imperforate part also prevents the blast from acting on the heavy rubbish, and, allowingit to drop upon the ratchet-bars over the said imperferate space, it will again be agitated and moved outward until the blast will take it again at the rear end of the imperforate space and carry it over the arms or extensions J J of ratchet-bars I I and out of the machine. By this construction the grain is most thoroughly separated from the chaff and all waste avoided.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a grain-separator, the oscillating bottom having hinged tail section or extension, and provided with longitudinal ratchet-bars extending slightly over said tail section, substantially as and for the purpose set forth.

2. The combination, with the imperforate oscillating bottoni, of the hinged tail section, perforated throughout the greater part of its length, and having imperforate rear end, and the blast-fan, substantially as and for the purpose sct forth.

3. The combination, with the tailings-spout and the oscillating bottom, of the hinged tail section having longitudinal ratehetfbars provided with rearwardly-extending 4arms extending over the tailings-spout of the machine, substantially as and for the purpose herein set forth.

4. The combination of the oscillating bottoni, the tail section having imperforate rear end and perforated front end, and hinged to the rear end of the oscillating bottom, and the deleoting-boards secured transversely under the same, substantially as and for the purposes herein set forth. Y

5. The combination of the tailings-spout, the oscillating bottom having longitudinal In testimony that I claim the foregoing asv my own, I have hereunto affixed my signature in presence of two Witnesses.
