HENRY A. HUEFFNER AND LEVI LASI-I, OF VIRGINIA, ILLINOIS.
DUST-ARRESTER.
a'PEGIFICATION forming part of Letters Patent No. 519,958, dated May 15,1894. Application filed June 8, 1893. Serial No. 476,994. (No model.)
To all whom it may concern.-
Be it known that we, HENRY A. HUEFFNER and LEVI LASH, both citizens of the United States, and residents of Virginia, in the county of Cass and State of Illinois, have invented new and useful Improvements in Dust-Ariesters, of which the following is a specifica- In order that our invention may be fully understood, we will proceed to describe it with reference to the accompanying drawings, in which- Figure I is a side elevation of our improved dust-arrester. Fig. II is a vertical longitudinal section thereof on the line IIII of Fig. III. Fig. III is a vertical transverse section of the same on the line III-III of Fig. II. Fig. IV is an enlarged horizontal section on the line IV-IV of Fig. V. Fig. V is an enlarged vertical section on the line V-V of Fig. IV.
1 is the casing.
9 is a rotary fan journaled in brackets 12 secured to the sides of the casing.
16 is the fan-drum having air-inlets 21 in its sides.
17 is a floor extending from the fandrum and forming'inconnection with the top of the casing an air-channel 18, leading from the airdrum. An angular projection 23 on the front end of the casing forms in connection with a vertical wall 27 a continuation of the airchannel 18 and is connected with the top and izlgort respectively by means of curved plates 26 is a separating chamber, With which the air-channel connects, located beneath the ceiling 25.
29 is an inclined wall extending from the ceiling to the drum.
30 is a series of supply chutes arranged in steps discharging into their respective hoppers 88 located over the primary separating chambers 34. Located between the hoppers are deflectors 169. The supply from the hoppers is regulated by the feed rolls 42 mounted in journal boxes 182, in connection with the pendent valves 46, adjusted by arms 54, supported on spiral springs 58, which encircle supporting rods 62, depending from the brack: ets 74 on which they are supported by thumb nuts 78. An angular projection 82 is secured to the forward side of each separating chamber to retard the elevation of the heavier grade of material which is deposited in the tight bottom of the same. Air ports 86 in the rear sides of the chambers opposite the projections provide air passages for the current created by the fan. These air-ports are controlled by valves 90, having arms 94 held by set screws 98 working in curved slotted holders 102.
170 is a portin the ceiling 25 providing a direct passage for a portion of the air current from the chamber 172 beneath, to the suctionchamber 173 above. This port is controlled by a valve 174 having an arm 175 secured by a set screw 176 working in a curved slotted holder 177. 106 are discharge ports fromthe chambers controlled by valves 110.
114 is the final primary separating chamber provided with a discharge port 115 controlled by a valve 116. The partition 178 is located between the last chamber 34 and the chamber 114 and is provided with a fiat end 179, against which the hinged deflector works.
180 are side chambers connected with the fan-drum. 117 are hinged current deflectors having arms secured by set screws 129 working in curved slotted holders 133. The
deflector 120 has similar means for its adj ust-.
ment. 187 is a dust chamber, located beneath the chamber 26, having a concave bed 138 in the floor 139.
140 is ascrew conveyer working in the bed and discharging the material through a port 141 controlled by a valve 142.
145 is an inclined overhanging screen extending from the ceiling to the floor 139.
146 is a'collecting and deflecting apparatus located over a flour chamber 152. Within the chamber 26 behind the screen 145 an endless chain 147 is mounted on rollers 148, carried by shafts 149 journaled in boxes 150 which are secured to the sides of the casing. A brush 151 is secured to the chain and clears the meshes of the screen.
153 is a concave bed to the flour bin in which a screw conveyer 168 Works for discharging the material through a port 154 controlled by a valve 155. The shaft 156 of this conveyor is journaled in boxes 157 secured to the sides of the casing.
between'the inclined wall andthe first The apparatus 146 has a perforated base 158 located over the flour bin-and discharges the material through the outlets 159 into the bin. The apparatus has a series of parallel partitions 160, that extend from side to side of the casing, except for a series of ports 161 through which the air current passes. Cross partitions 162 extend at certain intervals, throughout the whole length of parallel partitlons 160. The parallel partitions are set at an incline from the perpendicular, and are incased above with a top plate 163.
A series of deflectingframes 164 in Iform, with inclined plates 165, which project from and connect the end plates 166, constitute a system of deflectors and the inclined plates lead the air currents to the ports 161. The course *of the laden air currents, after they pass through the screen 145, (which has prevented the passage of most of the impurities) is through certain of the inlets 161, into the chambers 167, as shown by the arrows in Figs.
IV and V- and then passing throughthe chambers between certain of the cross'partitions, the currents are deflected along the next partitions, until'they reach their next ports'161 and so on'thronghouttheir course, the heavier ingredient as it eddies-around is precipitated against the deflectors and always tends to a lower level'than the lighter products, and the heavy product is thus mainly precipitated through the outlets 159 into the flour bin 152,
from which it is carried by the screw conveyer 168-and discharged through the port 154. The current that is both forced and drawn on its course by the rotary'fan thus effects as above described'the separation of 'the particles that are requi-red'to bedisassociated and then, almost pure, passes out through the final outlets 161, into the chamber 172, thence through the inlets 86 into the said primaryseparating chambers,wheresaid pure air becomes again laden with the constituents of the middlings under the rapid-suction and forced current, generated by the fan, it is driven on its renewed circuit.
