IMPROVEMENT IN SMUT-lVl-ILLS.
Specication forming part of vLetters Patent No. 175,632, dated April 4, 1876; application filed November 5, 1875.
To all whom it may concern Be itknown that I, PIETER VAN GELDER, Vryenban, near Delft, in the Kingdom of Holland, at present residing at Sefton street, Litherland, in the county of'Lancashire, England, a subject of Holland, have inventedor discovered new and useful Improvements in Apparatus for Removing Smutfrom Wheat, and for the better cleaning of wheat and other grains; and I, the said PIETER VAN GELDER, do hereby declare the nature of thesaidinvention, and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement thereofthat is to say:
This invention has for its object sundry improvement-s in apparatus for removing smut from wheat, and for the better cleaning of wheat and other grains.
For this purpose an apparatus is formed, consisting of a strong frame made of wood or iron, which supports a hollow cylinder made of natura-1 or articial stone. Within this cylinder revolves, on a vertical spindle, a hol low drum, made of iron or steel plate or wire. The grain is admitted in the space between the outside of the drum and the inside of the stone cylinder, and is introduced at the top of this space. A horizontal ventilator is fixed onto the Vertical spindle, and supplies .a strong` upair draft, which, forcing its way through the helicoidal grooves, carries before it all dust and impurities, which are dis charged through an opening near the top of the drum, and which, at the same time, improves the condition of the grain. The inside of the cylinder is provided with helicoidal grooves, which have the twist in the same or in the contrary direction to that in4 which the drum revolves, according to circumstances. provided with a rough surface. At the bot tom of the cylinder is an opening, by which the cleaned grain is extracted.
Figure l shows a vertical section 5 Fig. 2, a side elevation; Fig. 3, a horizontal section on the line A B, Fig. 1; and Fig. 4, a plan view of apparatus for cleaning grain, arranged in the manner above described.
A is the frame, to which is secured a vertical cylinder, B, of stone, by preference nat- The outside of the drum is ural sandstone, or an artificial stone composed, say, of two parts sharp sand, and one part Portland cement, the composition depending on the kinds of grain to be cleaned. rlhe stone cylinder is divided vertically into two parts, and is tied together with iron bands, as shown, and rests at its lower end on a horizontal Hoor, which forms part of the frame. C isa spindle passing d own vertically through the center of the cylinder. At its lower end it rests in a step, D, and at its upper end it passes through a bearing, E, and carries a driving-pulley, by means of which it can be revolved. Upon this spindle is fixed a hollow `drum, F, the periphery of which is formed of' wire-gauze, or of perforated sheet metal, with the metal set outward around the perforations, so as to form numerous small projections standing out from the sides of the drum.
' Above the top of the cylinder B is a faucasing, connnunicating with the cylinder by a central opening, G, in the bottom of the casing, as shown. Upon the spindle are also fixed fan-blades G1, by which air is drawn in from the top. of the cylinder B and expelled through the outlet G2. An upward current of air is thereby produced, both through the annular' space between the drum F and fixed stone cylinder B, and also from the bottom ot' this space through the interior-of the drum, a small portion of air being also drawn in through the inlet-pipe I.
The helicoidal grooves formed around the inner surface of the stone cylinder B are shown at Fig. 1. The grain to be cleaned is fed into the top ofthe space between the fixed cylinder and the drum through the pipe I, and as it descends it is carried round by the revolving of the drum, and finally falls away iu a cleaned state from the bottom ofthe space through the outlet-channel J, the impurities which have been rubbed off from the grain being carried away by the' current of air, which is drawn up by means of the fau through the outlet-cllarmel J and expelled from the fan-outlet G2.
Having 1thus described the nature of my invention, and the manner of performing the same, I would haveit understood that I claim-a l. The combination ofthe hollow stationary having openings in its periphery, and a rough outer surface, between which and the cylinder the grainspaee is formed, the spindle upon which the drum is secured, the suction-tan, the fan case, communicating with the cylinder at one end, and a single outlet for the escape ot" the grain and admission of air at the other end of the cylinder.
