E E into four longitudinal compartments 1 H is the top conveyor-sieve. This, like the V conveyer G, is partitioned into fourcompartments H H H 11 The bottoms of the COIB'. partments are allstepped to the left and connected at the left by convey'ers H with downward openings 1-1 Each of the said compartments 1 to 4 of conveyer E is formed with transverse openings through its floors, in which fit solid slides m m m m m thatex tend through side openings in the casing, and across the compartments, just back of each slide, are partitions m which' extend down nearly to the floor to divide the material that falls from the compartments F and F of v sieve F, and the floor of each of these com partments consists of sifting materialof varying mesh. For instance, one section may" be covered by No. 8 material andtheother's: by No. 6, 5, 4, 3, and 2 successivelyand accord-' ing to the degree of mixturenecessa'ry fordif-i ferent grinds of wheat. Either or any "ofthet slides mm m m m may be drawn out to ad-i mit the proper grade of flour directly from conveyer "E to the lower-conveyers.DD,from whence it is carried out-throughtheoutletbl, i while the rest is carried by the conveyerE to; outlet 0, and during this operation a=fan.J,z the .pipes of which enter the casing at J ,purifies the stuff by drawing air in through openings in and up through the sifting-floors of: compartments F and F of sieve F. The fluff! rising between the-troughs h passes out with E the air, while the heavierimpuriti'esdrop into the troughs and'are conveyed 0K to outlet h. l The casing A is designed to be hung from? an upper support by swinging arms and beneath is supported by a'short shaft dLth at. is eccentrically ball-and-socket jointed tothe.

hub'ofsa fly-wheelO, so that :byathe revolutions'of the fly-wheel the casing will be gy-i rated, and this gyration, in connection with: the forms of the conveyer-fioors,causes the material vto travel, as described, during the, sifting, purifying, and grading processes.

The inlet A is provided with partitions A forming-ducts,in which are open'i'ngsA A i A A that lead to the various sieves-anticanveyers, and to regulate the feed and control its distribution a cylinder composed-of two sections P P i-sinterposedbetweenthe month of the feed-pipe P and theinlet. The lower section P is formed with vertical partitions p, each-of whichi-s formed with triangular horizontal ifianges, one 12 at its top and .an-: other 19 at its bottom, and just beneath the bottom 'fianges the inner ends of four'triangular gatesg g g g are pivoted o.n:a1lug a 1 that projects downward from theintersection of thepartitions. The handles of rhesegates project through slots in the cylinder-section P, and by them the gates are turned to cut off or admit stock to the various compartments of the inlet A according as the compartments a "between the partitions are opened or closed. In its top the section Phas' q and a register-wheel q, having a handle turning on a pin a.

.In the modifications, Figs. 8, 9, and 10, the arrangement of sieves may be the same as in Fig. 1, but the purifier portion of the apparatus is outside of the casing proper-namely, in attached casings R R, each of which contains conveyers D, and above which is another conveyer D',the floor of which corresponds in structure with the floors of compartments 1 and 4 of conveyer E, Figs. 1 and 2, in being stepped to the left and having transverse openings that are closed by slides m m m m and side openings m". Above this is a sieve D which corresponds exactly with compartments F and F of sieve F, Fig. 5, and contains above its bottom channels h and has, also, the side draft-opening J, and then above this in the main-casing are the conveyors D and D and sieve D Between the two attached casings R R is a fly-"wheel S, which is formed with peripheral fan-s S, that make it also a fan-wheel. This lisiincl'osed in-a drum 8*, having side outletopenings sand a central opening in its top, thatis connected by a flexible pipe 8 with casing A and by other flexible pipes S with the openings J of the attached casings R, and the shaft N is eccentrically ball-andsocket ointed to the fly-wheel, as is the like shaft in Fig.1.

Having thus'fully described our invention, what we claim as. new, and desire to secure by Letters Patent, is-

7 1. The combinatiomwith the grader, of a ifly-wheel and fan combined and its casing and flexibletubular connections between the casing and the grader.

2. The combination,with the inlet of the main casing, of partitions and ducts leading therefrom to the varioussieves and conveyers and a divided inlet pipe and pivoted gates, substantially as described.

3. In a chop-grader, the combination, with the frame and means for actuating thesame,

of a stepped conveyer-sieve in the frame, di-

wided into four or more compartments, 'the steps of the respective adjacent compartments being arranged at opposite inclines, a stepped conveyer below the sieve at the end of the frame, movable slides in the end compartment containing the lower sieve, and troughs above the lower sieves, substantially as described.

4. ha chop grader, the couibinatiomwith the frame,"of a stepped'conveyer sieve therein extendingacross the interiorot the frame, 'cmveyers atthe ends of theframe, conveyersieves above theend conveyers, troughs-above 1 thefsieve, and means-for inducing air-currents through the sieveat the ends and above the troughs, substantially as described.
