UNITED STATES CHARLES WV. COOPER,
PATENT @FFICE.
OF NEW YORK, N. Y.
DUST-CO LLECTO R.
SPECIFICATION forming part of Letters Patent No. 450,327, dated April 14, 1891.
Application filed June 20, 1888.
To (all whom it may concern:
Be it known that 1, CHARLES W. COOPER, formerly of the city of Brooklyn, in the county of Kings and State of New York, now of the city of New York, in the county of New York, in said State, have invented a new and useful Improvement in Dust-Collectors, of which the following is a specification.
I will first describe my invention with reference to the drawings, and afterward point out its novelty in a claim.
Figurel is a longitudinal sectional elevation taken through the center of an apparatus embodying my invention; and Fig. 2 is a transverse section of the same, taken through the line no a: of Fig. 1, looking to the right. Fig. 3 represents a central sectional elevation of a modification of the apparatus, and Fig. 4 represents a transverse section in the line y y of Fig. 3.
Similar letters of reference designate corresponding parts in all the figures.
Referring first to Figs. 1 and 2, A is a tight casing or chamber in which revolves a shaft B, having attached to it a disk 0, that carries anumber of fans D D upon each side, respectively, as shown in, the drawings, the casing or chamber being large enough to have ample space radially outside of the edges of the fans and disk for separating the air and dust.
E is an opening through the casing, preferably circular and concentric with the shaft for the inlet to the apparatus of air charged with the dust to be separated from it, and F is a similar opening, somewhat larger than E, in the opposite side of the chamber A for the discharge of the air after the dust has been separated from it.
The disk 0 constitutes an intercepting de-' vice between the openings E F.
G is a pipe for conveying the dust-laden air into the apparatus, and H is a chamber or passage surrounding the shaft B to form communication between the pipe G and the inletopening E.
I and J are the bearings for the shaft B, which support it in line between the openings E F, and K is the pulley to drive the said shaft.
L is an enlargement of the casing below the fans and constitutes a pit for the collection of the dust after it has been separated from the air. This pit is provided with a door M,
$erial No. 277,693. (No model.)
through which the dust may be from time to time removed. The pipe G is supposed to lead from a room, pulverizing-mill, or other chamber containing air laden with dust which is to be separated from it, and it is the discharge-pipe from such chamber, while at the same time it is the supply-pipe for air into the separating apparatus.
In operating the apparatus the shaft B is made to revolve rapidly, carrying with it the disk 0 and fans D D, and the rotation of these fans will produce rapid rotation of the air between and around them, thus giving centrifugal force to the air. While the fans and air are thus in rotation the centrifugal action of the fansD upon the air tends to force it around to the other side of the disk 0 andout of the opening F, while that of the fans D tends to force it in just the opposite direction. It is clear, therefore, that if the conditions on both sides of the disk were exactly the same these tendencies, Working in opposition, would balance each other and the air would not be propelled by the fans in either direction through the apparatus. Hence to cause the air, by the action of the fans themselves, to enter at E and discharge at F it is necessary to give greater centrifugal force by means of the fans D to the air on the inlet side of the disk or intercepting device 0 than is given to it on the exit side of the fans D; This result may be produced in various ways. In the example represented in Figs. 1 and 2 the fans on the two sides of the disk arealike and in balance, and the greater centrifugal force on the inlet side is produced by making the opening F larger in diameter than the opening E. A current of air being thus produced,it will flow in through the pipe G, opening E, between the fansD in the direction of the centrifugal force produced by them, around the outside of the disk 0, then between the fans D, against the less centrifugal force produced by them, and finally out through the exit-opening F. This current through the fans is in addition to the current of rotation with and around them and is very slight rela tively to the rotary current. It may be considered as a continuous leakage through the opening F from the rapidly-rotating belt of air, which leakage is continuously supplied through the opening E. The belt of air rotating around the fans D D Will contain the dust that enters with it through the openings E, and the dust being heavier than the air will have greater centrifugal force and therefore fly to the outer part of this belt, and will resist the tendency to be carried toward the center by the air that is passing out through the fans D and opening F. The dust that is carried around by the outer part of the rotating current of air will gradually escape from the influence of this current and settle to the bottom part of the pit L,Where the air is comparatively quiet. From there it may be removed from time to time through the door M.
In the example of my invention shown in Figs. 3 and 4 the disk or intercepting device 0 is stationary, the fan shaft E passing through it, and the fans D D being attached .to said shaft by arms d and hubs Z). The disk or intercepting device 0 is in this case held in place bybraces c, which attach it to the case A.
I have described the intercepting device 0 asadisk; but by the term dislfildo not mean to limit the device to a flat plate, as the said device may be of any form that will intercept the passage of the air between the openings E F and leave a sufficient space on each side of and around it Within the chamber A.
in cases Where the dust is not to be saved, but Where the object is simply to purify the air from it, a pipe leading from any part of the casing L, starting at a sufficient distance from the center of rotation, could be used to carry a portion of the air laden With the concentrated dust abstracted from the outer art of the rotating air-belt and to discharge it Wherever desired.
What I claim as my invention, and desire to secure by Letters Patent, is
In a dust-collector, the combination, with a chamber having an inlet-opening and an op posite outlet-opening of larger size, of a r0- tary shaft between said openings, a disk surrounding said shaft, and fans on opposite sides of said disk carried by said shaft, substantially as herein described.
