Letters Patent No. 92,809, dated July 20, 1869.

IMPRovED GRAIN-CLEANER arm -sMU'r-MAGHINE.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, JOHN` FERGUSON, of Fall River, of the V`county of Bristol, of the State of Massachusetts, have invented Va new and useful or improved Machine for Pearling and Cleansing of Wheat or other grain capable of Vbeing treated thereby; and Ldo hereby declare the same to be fully described in the following specification, and represented in the ac ornpanying drawings.

Ot such drawings- Figure l is a perspective view ofthe machine, as it appears with the upper half or portion of' its cylindercase removed from the remainder thereof.

Figure 2 is alongitudinal and vertical section ofthe machine. Y

lFigure 3, a transverse section of the cylinder and its rotary stone. Y

In figs. 1 and 2, A denotes the frame of the machine, there beingextended through it lengthwise, and sustained by it in suitable boxes, a shaft, which, in fig. 2, is represented at M2, and in iig. 3 atAM.

This shaft carries a grindingcylinder or stone, (shown at O2 in fig. 2,and at O in iig. 3,) whose pcriphery is fluted or suitably grooved, the same being as shown in section iu fig. 3.

The stone is concentric with and revolved by the shaft whell in operation, and is arranged within what is-termed the hollow cylinder, (marked Bl in fig. 1, B2 in iig. 2, and B3 in iig. 3,) which is a frame inserted in the said shaft, so as to be capable of being revolved freely thereon, and in a direction opposite to th'at in which the stone is revolved.

A driving-pulley,12, is fixedon-the shaft M2, to eni, ab'le such shaft to be put i'n revolution by an endless belt, driven by a suitable motor.

Furthermore, a train of gears, G', H', H', and F', arranged as represented in tig.1, serves to transmit rotary motion from the driving-shaft to the hollowv cylinder.

Within the said hollowjcylinder, and arranged about the stem, in manner as-shown in iig. 3, is a series of brushes, (each being marked C1 in fig. 1, C2 in fig. 2, and C3 in iig. 3,) they being movable in radial ldirections, and suppo1tedagainst springs, as shown atxlin fio. 3.

, In each of these troughs there are placed several' triangular deectors, pivoted to the trough, and provided with cranks, pivoted to a bar.

In g. 1, the bar is shown at E and the cranks at el. In fig. 2, the bar is represented at E", the cranks at e2, and the deectors at N2. In iig. 3, the bar is shown at E, the cranks at e, andthe delectorsat N3.

In Figure 4, a trough is seen at D, the deilectors l thereof at N4, and a next adjacent brush at 0*.

By means of the bar and the series of cranks of the deilectors, each set of them may have their oblique portions within the trough changed or varied, as circumstances may require, to cause the grain to be moved slower or faster from end to end of the machine, as circumstances may require.

'.Ihe rotary hollow`cylinder, with its brushes andforamin'ous and corrugated troughs, and their several series of deilectors, is disposed within a suitable case, R, (see iig. 2,) against one end of which there is arranged a fan-blower, (shown at J in fig. 1, and at J2 in iig. 2.)

The grain enters the case at its opposite end, through a spout, shown in g. 2, with an arrow upon it A conduit, S2,1(see iig. 2,) opening out of the said@vv end of the case, extends over'the case, and opens inta, that of the fan-blower, at or near its centre. f

The lower part of the case Rl is arranged as hoppers, having openings d through their lower parts.

- These openings may be provided withvtraps or valves, to opendownwards.

An air-box or conductor, U, formed as shown 1n iig.

2, is arranged against the case Rl andthe fan-blower,

in manner as shown in g. 2.

The case R and-the conductor U communicate by an opening, V, which is situated directly over the airinduct b2 of the conductor.

The said conductor has an educt or dischargingspout, c2, to whose lowcr end a hap-valve, to open downward, may be applied.

' The conductor leads air into the fan-blower case.

The operation of the machine may be thus explained:

The grain, on entering the machine through the spout X, (see fig. 2,) will pass into the space within the hollow cylinder, and-thence into the foraminous troughs, which, as the said cylinder-revolves, will carry up the grain and deposit it on the stone.

By the conjoint action of the said stone and the selies of brushes, the grain will be pearled, and much ofthe loose particles and dust will escape through the fine holes of the trough.

The current of air; produced through the case by the fan-blower will cause the dust to be discharged therefrom.

The grain, after being operated on, will drop through the opening V, where it will meet the iurushing current of air passing into'the conductor.

The smut and extraneous matters will be separated from the'gran by this current, and the y most of such will be drawn into and discharged from the fan-blower, the heavier parts passing off through the ednet o?.

VVhztt I claim as my invention in the said machine,

is as follows, viz:

`l. I claim the arrangement and combination of the series of foraminous troughs and the series of brushes of the hollow cylinder with the rotary stone, all constructed its herein described, and so disposed within at ease, provided with zt fam-blower, as to operate therewith, substantially as hereinhefore speoitied.
