* TED" swag AUGUST o. PosnEmoF NEW onLEANs, L ouIsIAnA-Q nns'r-ooLLEoroR.
To all whom it may concern Be it known that 1, AUGUST 0. PosNnR, a citizen of the United States, residing in the 'city of New Qrleans, parish of Orleans, and State of Louisiana, have invented a certain new and useful Improvement in Dust-Col-f lectors, of which the following is the specification.
My invention relates to that class of dust collectors, which is termed the cyclone type,
t and has for its object to provide a machine,
which will produce a higher efficiency, and as av consequence a higher vacuum in the inlet 'pipe adjacent the collector.' vI have discovered that by locating a smaller'col- 'lector within the outer one and. extending the tubular guard of the interior collector.
up through thecenter of the purified air exit of the exterior machine that the chiciency of the machine is greatly increased. This is believed to be due to the fact that instead of the central portion of the air escape being occupied either by a dead air space or an active ingoing current of air it is taken up by a positive-outgoing current of air, thevelocity of which differing from discharge 7, and is provided with a spiral current, but under ordinary circumstances showing a decided ingoing current. My means of accomplishing this'object may be more readily understood by having reference to the accompanying drawings, which are hereunto annexed andare a part of this specification, in which:
Figure 1 is a side elevation,'part of the outer casing being broken away showing the interior construction in section. Fig. 2 is a top or plan view of the same. Fig. 3 is a fragmentary detail View showing the adjustable valve.
Similar reference numerals refer to similar parts throughout the entire description. For the purpose of illustration I have shown a collector in which both the upper and lower chambers are conoidal, though it will be apparent to persons skilled in the Specification of Letters Eatent.
that the upperseparating chamber may be cylindrlcal 'w1thou t departingfrom the sp rit of my invention asclaimed- 3 .PatentedNov.2,1915. Application filed September 13,1911. "'seria1no.e49,142.
As shown in "the drawings, thecollector is formed with an" upper separating chain; ber'l,wh'1ch 1s provided with a spiral inlet 2',
aconical dust discharge 3 attached to the 7 lower part of the upper separating chamber 1. The purified air escape, ispr ovided with a'short tubular guards preferably of cylin-' drical form. Leading from the annular space formed between the tubular guard and l the wall of the separating-chamber .1 I
provide a small dust pip This p p 1 I crates to carry oif the'finenearly impalpable dust which travels" upwardly along the wall of the upper separating chamber and which would be otherwise carried out'through the escape provided for the escape ofthe puri V V fied air. v, V
Nithin the upper separating chamber 1 I mount a similar separating chamber 5, the walls 6 of which coincide invtheir taper with the taper of the walls of the separating chamber 1'. This separating chamber has securedto itslower portion a tapering-dust inlet 8, which extends. as more clearly seen in Fig. 2, to a point adjacent the wall of the upper separating chamber 1. This spiral is a continuation of the one formed by the inlet on the exterior separating chamber. This has been found to operate most satis- .factorily when located at a point near the opening ofthe tangential inlet 2. The mlet 8 is provided with a hingedportion, better seen in the detail views, which may be moved, as indicated, by dotted lines, nearer or farther from the wall of the outer separating chamber'l. 1
I An annular 'member'9 constructed ofjflat metal encircles the walls ofthe inner separating chamber 5 and a dislnlO is located in its interior, there being an annular space be tween the edge of the disk and the wallsof:
the inner conical dust' discharge 7. y The upper separating'chamber .5 is provided with a tubular guard 11, which extends upwardly through the central portion of the purified air escape 4. The result of this construction is that the entire central portionof the purified air escape is taken up by the air escaping through the tubular guard 11, and
a careful examinationfails to discloseany '3 4, is secured in any suitable manner a pipe (not shown) leading from a Vacuum producing fan, by which the dust-ladenair 1S drawn into the upper separating chamber where it is whirled around, the heavier particles of dust being thrown outwardly to the periphery of the separating chamber and passed down along the walls through the crnical dust discharge 3. As the whirling air current in its travel reaches the point where the spiral inlet 8 opens into the air chamber, it passes through the said tangential inlet into the internal separating chamber where a further separation takes place, the dust passing, while the purified air, escapes through the tubular guard 11. It will be apparent that the spiral will have carried the material downwardly so that a considerable separation will have taken place before the air current reaches the inlet 8. By this form of construction no interference is caused to the gyrating movement of the air and the operation in the internal separating chamber serves to collect that fine dirt,
which as a rule escapes from the ordinary produced by my machine can be determined and be'materially increased by adjusting the hinged porticn 13 on the tangential inlet 8.
vHaving described my invention, What 1 Copies of this patent may be obtained for regard as new and desire to secure by Letters Patent 1s:
1. A dust collector comprismg an outer chamber and an inner chamber, each chamber having a spiral passageway, each pas sageway having a mouth extending beyond the periphery of the chamber to which it is applied, the mouth of the inner passageway being in a position to receive acurrent of air from the outer passageway, and an annular flange secured to the inner chamber for supporting the air current above the central. plane of the chamber and a separate purified air discharge outlet for'each chamber.
2. A dust collector comprising an outer chamber and a chamber supported within the outer chamber, a spiral passage way for each chamber, the mouth of the passage way applied to the inner chamber being arranged in a position to receive, air from the passage way of the outer chamber, each chamber having a dust discharge portion, the dust discharge portion of the outer chamber being separate from the dust discharge portion of the inner chamber, and means for supporting a current ofair above the central plane of the inner chamber and a separate purified air discharge outlet for each chamber.
In witness whereof I have signed the foregoing specification. a
