COMBINED THRASHING-MACHINE AND CLOVER-HULLE R.

SPECIFICATION forming part of Letters Patent No. 230,562, dated July 2'7, 1880. Application filed A hi 21880. (No model.) Q

. T all whom it may concern Be it known that I, HENRY A. MILLER, of Findlay, in the county of Hancock and State of Ohio, have invented certainnew and use ful Improvements in Combined Thrashing-Machine and Olover-Huller 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 plan or top view, the roof of the machine having been removed; and Fig. 2 is a longitudinal vertical section.

Similar letters of reference indicate corresponding parts in both the figures.

lhe object of this invention is to produce a thrashing-machine for wheat and other grain which is adapted also to be used as a clover thrasher and huller 5 and it consists in the construction and combination of parts, as hereinafter full y described,and particularly pointed out in the claim.

In the drawings, A is the frame of the machine, in one end of which is the throat B, through which the grain or clover (as the case may be) which is to be thrashed is fed. Back of the throat B is the concave O, in which runs the thrashing-cylind erD, of the usual construction.

E is the shaking pan or frame, which is suspended, by suitably-arranged hangers c c, inside of the machine, back of the concave and thrashing-cylinder, and has a perforated bottom, beneath which, and affixed removably upon the sides of the shaking-frame, is a sheetmetal plate, E, corresponding in length and width to the shaker E, of which it forms a detachable part.

F is the straw carrier and separator, which, in like manner as the shaker E, is suspended by hangers f f, and has a perforated bottom, underneath which is a permanent sheet-metal floor or plate, E, which is secured upon and forms a part of the carrier-frame. The shaker E overlaps with its rear end the straw carrier and separator F F, and a reciprocating or vibrating motion is imparted to the shaker 2nd carrier by pitmen a b and a rotating shaft,

0, in such a manner that they will reciprocate simultaneously against each other.

If it is desired to use the machine for thrashing wheat, the grain is separated from the straw, after it has passed the thrashing-cylinder, by the perforated shaker E and carrier F, by their vibratory motions, the grain falling down through the perforations, in the first instance, upon the fioor E, which vibrates with the shaker and delivers it (the grain) upon the forward end of the separator and carrier F, where it falls through the holes down upon the imperforate bottom F, and is dropped at the rear end of this into the vibrating shoe G, upon the riddles of which it is subjected to the blast from the fan H in the usual manner. Such of the grain as is not separated from the straw during its passage over the vibrating shaker E is mixed with the straw, received upon the separator and carrier F, by the vibrationsof which it is further sifted, being caught, as it drops through the perforations, upon the imperforate floor F and stepped chute I, by both of which it is conveyed down into the shoe, while the straw is delivered to the stacker at the end of the carrier F in the upper rear corner of the machine.

When, on the other hand, the machine is to be used for thrashing and hulling clover-seed, the detachable shaker-floor E is removed and the riddles in the vibrating shoe G are changed for othersof a finer mesh. The clover is fed through the throat B to the thrashing-cylinder in like manner as the wheat but as, after thrashing, it leaves the concave and is received upon the vibrating perforated shaker E, the

- seed drops down through the perforations upon a rigid horizontal floor or diaphragm, K, over which travels, in the direction of the arrows, a slatted apron, L, suspended between and operated by the rollers l l l. As the seed is received upon floor K it is carried by the slats of the apron L toward the forward part of the machine and discharged at the end of the floor down into the concave M of the hulling-cylinder N. As, after hulling, the seed leaves the cylinder it is received upon an inclined'plane or floor, K, where it again meets the slatted apron L on its return trip from the lowermost roller, 1, and is by this apron carried up the inclined plane to its upper end, Where it (the seed) is dropped into the riddles of the shaking shoe and cleaned by the blast from the fanning-mill in like manner as the wheat.

To facilitate the operation of thiashing, a beating-cylinder armed with teeth may be placed back of the thrashing-cylinder in the upper part of the machine; but, as this is a common expedient in threshing-machines, I have not shown it in the drawings.

The several cylinders and rollers, with theirshafts, are rotated by pulleys and endless belts or intermeshing cog-wheels in a manner well understood, and which does not, therefore, require illustration and it is obvious that when the machine is used for thrashing wheat the bands for operating the hullingcylinder N and endless slatted apron L may be unshipped, as these only operate when the machine is used for hulling clover.
