IMPROVEMENT IN GRAIN-SEPARATORS.

Specification forming part of Letters Patent No. 155,404, dated September 29, 1874; application filed October 20, 1873.

To all whom it may concer-n:

Be it known that I, FREDERICK A. BALcH, of Hingham, in the county of Sheboygan and State of Wisconsin, have invented a new and useful Improvement in Grain-Separators; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure l is a perspective view of my machine. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a sectional end elevation of the same.

This improvement relates to that class of separators wherein grains of diierent dimensions are separated by means of revolving cylinders having their surfaces indented with cells of suitable size, to receive the smaller grains and convey them away/,"aud it consists of a method of supporting the separator-cylinder by hanging the ends of the same upon rollers placed within said ends, said rollers having bearings in boxes fixed to the frame.

That others may fully understand my iluprovement, I will particularly describe it.

I prefer to employ a separator constructed in accordance with my patent granted August 15, 1871, and numbered 118,094, and for description of the general construction and operation of said separator I hereby refer to said patent.

A represents the general frame-work to support my machine, though the construction and arrangement of the same maybe varied to suit the particular circumstances or requirements of the place wherein the machine is to be set and operated. B is the cylinder of the separator', constructed with a shell perforated to form cells of the size required to receive and carry away the kernels of cockle or very small grain, and surrounded by a jacket, b, which I iind advisable to make removable, for the purpose of readily cleaning the cylinder B and its cells. The cylinder B I mount upon rollers C C upon a shaft, D, which passes through said cylinder, and has its bearings in frame A. At the outer ends of said shaft are the band-pulleys d cj, the former ot' which receives the belt whereby motion is communicated from the prime motor. Small rollers g g are placed upon the frame to steady the motion of the cylinder.

The cockle and very small grain are taken up by the cells in the revolving cylinder, and dropped into the cockle-trough E, which passes through said cylinder, and is attached at its ends to the frame-work A. A feedscrew, F, is placed in the bottom of the trough E, to convey the cockle which drops therein to one end, whence it is discharged through a spout, IL, while the wheat is discharged from the end. of cylinder B into a spout, c', and thereby conveyed to the proper receptacle.

Above the separator B, and-at a convenient distance therefrom, I place a screening apparatus, constructed to screen out all of the larger kernels by permitting the smaller ones to pass through said screen, and thereby I not only separate the larger grain and grade it, but the labor of the separator B is lessened in proportion to the quantity of large grain separated by said screen.

The revolving screen G is constructed with ble mesh to permit all the cockle and small grain to pass through. This is received in a trough, K, at the bottom of the screen-case, and conveyed to 011e end thereof by a screw or other suitable conveyer, and discharged through a spout, m, into the separator B, while the larger grain is discharged from the tail end of said screen into a trough, a, and spout, which may discharge it into spoutz' with the small grain, ,or into a separate receptacle, as may be required.

The screen-conveyer and revolving screen are operated by belts from pulleys cf.

A hopper or spout, I, may be employed to convey grain to the screen, as may be most convenient and desirable.

Having described my invention, what I claim as new is- In combination with the revolving cockleseparator B, the Han ged roller C upon the shaft D within said separator, to support the same in the manner described, and cause the same to rotate with unobstructed ends.

FREDERICK BALCH.
