ROBERT H. KLEISER, OF DE WITT, ARKANSAS.

GRAIN-SCOURING MACHINE.

Application filed October 29, 1913.

To all whom it may concern:

Be it known that 1, ROBERT H. KLEISER, a citizen of the United States, residing at De \Vitt, in the county of Arkansas and State of Arkansas, have invented new and useful Improvements in Grain- Securing Machines, of which the following is a specification.

This invention relates to machines for scouring and cleaning rice and other grains, and it has for its object to simplify and improve the construction and operation of this class of devices.

An object of the invention is to provide the brush member with flexible stops to prevent grain from working down between the bristles without passing in active contact with the screen.

WVith these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings,Figure 1 is a side elevation, partly in section, of a machine constructed in accordance with the invention. Fig. 2 is a detail view partly in section and partly in perspective showing a portion of the brush member. Fig. 3 is a vertical sectional view taken on the line 33 in Fig. 1. Fig. 4 is a sectional detail View illustrating a modification.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved machine includes a scouring member A of conical or frustum shape, said member being mounted base upward on a shaft 15. The member A is composed of annularly flanged heads 16, 17 holding and clamping between them a plurality of staves 18 having bristles 19 of wire or other suitable material. The heads 16, 17 are connected by clamping rods 20. The shaft 15 is stepped at its lower end in a socket 21 formed in a supporting bar 22 carried by vertically adjustable screw threaded rods 23 Specification of Letters Patent.

"that extend through a floor or platform 24% and are provided with nuts 25, whereby adustment may be effected.

Supported above the floor or platform 24: by means of legs or uprights is a casing 27 through which the shaft 15 extends and within which is supported a conical screen 28 that surrounds the brush member A, said screen being supported and reinforced in such a manner as to enable it to efficiently resist wear. The screen 28 is concentric with the member A, and the space between the latter and the screen may be varied by vertical adjustment of the shaft 15 by the means described. One or more bearings for the shaft may be provided, as indicated at 29, in addition to the step 21.

The scouring member A is provided with one or more annular bands or flanges 30 formed of leather or other suitable flexible material, each of said bands bein of a width substantially equal to the length of the bristles. These bands may be secured by means of fastening members, such as spikes 31, driven into the staves 18 and havlng forked heads 32 wherein the band may be retained by fastening means, such asa rivet 33. Any other convenient means for mounting the flanges 30 may, however, be employed, as shown for example in Fig. 4, where the flange 30 has been shown as being mounted on an L-shaped bracket member 10. It will be observed that the flanges 30 do not extend beyond the bristles 19 so that said flanges will not obstruct the space between the brush member and the screen; the flanges, however, will obstruct the interspaces between the bristles, thus making it impossible for any grain to work down between the bristles without coming into contact with the scouring surface of the screen.

A driving pulley 31 adapted to receive motion from any convenient source of power may be mounted in any available position on the shaft 15. An inlet spout 35 is provided whereby the grain to be operated upon will be discharged on the head 16 at the upper end of the scouring member. Receiving hoppers 36 and 37 are also provided through which the cleaned grain passing over the screen and the bran and impurities that are discharged through the screen, respectively, may be spouted to a place of deposit.

In the operation of this invention, the shaft carrying the scouring member A is rotated at a desired speed, and the grain that is to be scoured is discharged on the head 16, whence it is distributed by centrifugal action in the direction of the screen 28. The grain passing down inside the screen will be subjected to thescouring action of the brush, and the'bran and impurities be-" ing thus removed will pass through the screen and the casing and be discharged into the hopper 37. Any grain attempting to work down through the inter-spaces between the bristles will be checked or intercepted by the flange or flanges 30 and will be compelled to pass into the space between the brush and the screen where it must of necessity be subjected to a scouring action. The clean grain will be discharged from the screen into the hopper 36.

It is obviousthat in the construction of a machine based on the principle of this invention, any desired number of units may be employed, and that such units may be arranged side by side in tandem or other relation, it being also feasible to arrange several units in vertical series, thus enabling a plurality of scouring members to be mounted on a single shaft. Any such arrangement would obviously be within the" scope of the present invention.

'Having thus described the invention, what is claimed as new, is-

1. In a machine of the class described, a cone-shaped scouring member comprising annularly flanged upper and lower heads, staves fitted between said heads and having bristles constituting brushes, clamp rods connecting the heads, and an annular resilient flange surrounding the scouring member and projecting between but not beyond the bristles.

2. In a machine of the class described, a cone-shaped scouring member comprising annularly flanged upper and lower heads, staves fittedv between said heads and having bristles constituting brushes, clamp rods .copiel of this patent may be obtained for jecting between but not beyond the bristles, in combination with a cone-shaped screen surrounding and concentric with the scouring member, a vertical shaft carrying the scouring member, and means for effecting adjustment of the shaft to vary the space between the scouring member and the screen.

t. In a machine of the class described, a scouring member of circular cross section supported for rotation and having radially extending bristles, in combination with an.

annular flange supported in the interspaces obetween the bristles, said flange being of a width approximately equalto the length of the bristles, and a screen of circular cross section surrounding, concentric with and spaced from the scouring member.

5. In a machine of the class described, a scouring member of circular cross section supported for rotation and having radially extending bristles, in combination with an annular flange of flexible material fitted in the interspaces between the bristles, and supporting members for the said flange having forked heads wherein the flange is mounted.

In testimony whereof I ailix my signature in presence of two witnesses.
