SPECIFICATION forming part of Letters Patent No. 422,776, dated March .4, 1890.

Application filed September 30, 1889. derial No. 825,536. (No model.)

To ctZZ whom, it may concern:

Be it known that I, JAMES F. HATFIELD, a citizen of the United States, and a resident of Dublin, in the county of Wayne and State of Indiana,have invented certain new and useful Improvements in Grain-Separators; and I do declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same, reference being had to th e'aocompanyin g drawings, and

to letters of reference marked thereon, which form a part of this specification.

Figure I of the drawings is a representation of a side view of the separator, illustrating the invention as also in dotted lines the second position of the upper shoe-lever. Fig. 2 is a view of the opposite side of the separator. Fig. 3 is a longitudinal section, and Figs. 4: and 5 are details.

This invention relates to certain improvements in grainseparators; and it consists of the novel combination and construction of parts, as will fully appear from the following description and accompanying illustrations.

In the embodiment of my invention I employ a closure or casin g A, which is suitably supported in position upon legs or standards Ct Ct, disposing in one end of said closure in the upper part a rotary fan B, which is suitably driven.

C is an inclined upper shoe carrying a sieve C, and having one end arranged under the usual hopper D, secured at its ends to and between uprights a, fastened to and project ing upward from the casing or closure A. This screen or sieve has a smooth upper and is preferably of zinc, and to effect a separation of the grain from oats and white caps, a smooth endwise movement is imparted to This is obtained by" employing in connection with the actuating mechanism presently described) of the shoe a right-angle) lever D, connecting or pivoting its lower end to the closure or casing and providing a pivotal connection, as at 7), between it and the shoe in alignment with the lower pivot. In this treatment of the grain the oats and white caps slide over and out of the sieve or screen away from the grain, from the grain, however, an up and down In the removal of chaff.

extension cl of the shoe C, and fulcrumed, as

at cl, upon the side of the casing or closure A, the low er end of said lever having connection with a pitman 6, connected to an eccentric c 011 the end of the fan-shaft. This mechanism is for actuating the sieve or screen car-' rying shoe 0.

F is a lower shoe, which has an opposite in clination to the upper shoe C and carries a series of sieves or screens F F 1 for the fur ther treatment of. the grain. This shoe has opposite downwardly extending arms or pendants f, connected thereto a short distance in ward from its lower end, and pivoted near their lower ends it may be to downward. ex tensions of the hopper supporting uprights a. These arms or pendants may have a common pivot by employing a rod f extending through them and secured or bearing in the uprights. This shoe also has connection. with and is actuated by the lever D.

Arranged so as to stand a short distance be low the shoe F are brackets G G, which are adjustably connected to the inner sides of the closure supporting standards or legs a a to vary the distance between the latter and the shoe. It will be observed that as the shoe F is actuated through the lever D it will, by the aid of its pivoted pendants or arms f and the brackets G, against which it strikes, be rocked up and down from end to end through the jarring motion imparted to the shoe, and screens will dislodge any adhering grain and thus liberate it, permitting the whole of the grain to pass out of the screens. The screens or sieves F F F are stair steps in length, their rear ends terminating successively one inward from the other,'and discharge, respect ively, intoa series of chutes or spouts g g 9 arranged in the rear lower end of the shoe F. The chaff is carried off into the trunk h, at the rear end of the casing, the bottom of which. inclines from. the center laterally in two directions. At the base of each incline of the bottom of the trunk. h is a discharging opening or outlet h for the contents thereof.

Instead of causing the lower shoe to carry the grain receiving and discharging chutes or spouts as heretofore, which puts that much more weight on the gearing or actuating mechanism, I provide a supplemental shoe H for carrying the spouts or chutes, designated at 71 and impart avibratory motion to said shoe by connecting it, through pitmen or rods h with the lower ends of the pendants or arms f, dislodgingany possible adhering. grain therein,

I is a rod, one provided for each sieve or 1. In a grain-separator or fanning-mill, the combination, with the upper or top screenshoe and its actuating mechanism, of-the rightangle lever having changeable connections with said shoe, one at its upper end and the other at its angle, the lower end of said lever having a fixedpivotal connection with the "closure or casing, substantially as set forth.
