ARTHUR HENRY VAN DUZEE, OF LEAVEN\VORTH, KANSAS.
CENTRIFUGAL SEPARATOR.
SPECIFICATION forming part of Letters Patent No. 325,288, dated September 1, 1885.
Application filed August 11, 1884.
To all whom it may concern:
Be it known that I, ARTHUR HENRY VAN DUZEE, a citizen of the United States, and a resident of Leavenworth, in the county of Leavenworth, in the State of Kansas, have invented certain new and useful Improvements in Centrifugal Separators, of which the following specification is a full, clear, and exact description, reference being also had to the ac companying drawings, in which- Figure 1 is alongitudinal vertical section in the plane of the dotted line 00 m, Fig. 5. Fig. 2 is a detached perspective view of a section of the conveyer-valves. Figs. 3 and 4 are details of the combined tailsupporting box and oil-catching chamber or hood. Fig. 5 is a cross-sectional view on the line 3 1 of Fig. 1. Fig. 6 is an elevation of the feed end of the machine. Fig. 7 is a sectional detail of the main shaft and one of its bearings. Fig. 8 is a top view of one end of the machine, a part of the frame and case being shown cut away to exhibit the gearing beneath.
A is the outer casing or frame, through the length of which the main driving-shaft B passes, and having a hopper-bottom, A", in which two screw-conveyers, 0 G are arranged to run side by-side, as shown in Figs. 1 and 5.
Upon the top of the wall E, which divides the conveycrs O 0 is secured arod, a, around which one end of each of a series of valves, F, is bent, each valve being thus hinged to the rod (1, so that it can be turned over to either side to rest by its upper end upon either of the sides of the hopper-bottom A", to cause the material falling from the reel to be guided entirely into one or a portion into each of the conveyers G 0 By this simple means the 7 material may be cut off at any point and guided into the conveyers, as required.
Upon the shaft 13, inside of the casing A, are secured spiders or circular beater-supports G G having inclined beaterstrips b, the strips being parallel with each other and with the shaft B, the whole thus forming a beater-cylinder, as shown. The spiders G G are formed in two equal semicircular sections and clamped together at the hubs G3 and at the periphery, so that they can be attached to the shaft B at any point. The beater-cylinder may thus be attached without the use of key-seats, set-screws, or other such means,
(No model.)
which weaken the shaft and render it liable to spring out of line. By this manner of attachment, however, no tendency to spring ex ists in the shaft.
Surrounding the beater-cylinder is a bolting-cloth-covered reel consisting of a cast-iron head-disk, H, and tail-disk H and connecting-ribs H.
The head-disk H is provided with an outwardly-projecting central bearing-ring, H, fitting through the wooden head end of the easing A, and having a gear, I, cast upon the outer face of this projecting bearing and adapted to engage with a pinion, 1", on a shaft, 1 on the casing A.
The tail-disk H is provided at its center with an outwardlyprojecting hollow stud, K, fitting into a box or collar, K the latter supported by set-screws d (l in a shell or sleeve, K. This sleeve is supported by a stud, K,
in a bracket, K, on a bridgetrce, K", across the tail end of the frame A.
The tail end of the shaft B passes out through the stud K, (which is made large enough so that the shaft does not touch it,) and is supported in the sleeve K by a box or collar, K and setscrews d (1, similar to the collar K and set-screws d d".
The stud K is adapted to be adjusted higher and lower in the bracket K by a set-screw, K so that the shaft B and reel H H H may be adjusted higher or lower, and by means of the set-screws d d and d" d the reel and shaft may be adjusted laterally, independently of each other. By this means the reel and shaft may be easily adjusted without stopping the machine or removing any of the parts.
K is a hand-hole, through which the adj usting-screw K can be reached and operated.
The sleeve or shell K is provided in. its lower part with a depressed channel, m, running downward and outward to form a conduit to convey the oil that drips from the bearings or collars out over a lip, m away from the machine, and prevent it from running in and mingling with the flour or tailings. The inner edges, m, of this shell are bent inward toward the shaft 13 to form a lip to retain the oil, 850., and turn it outward and cause it to flow down the channel.
The ribs H are formed of sections of angle or L. iron, set as shown, and filled on the outside with angular wooden stripse, to which the bolting-cloth is tacked.
The head and tail disks H H are formed on their outer rims with as many flat sections as there are ribs H (in the drawings eight,) and on each of these flat sections, between each pair of the ribs H, a wooden strip, g, is secured, to which the bolting-cloth is tacked. Just beneath these wooden strips and parallel therewith, the tail-disk H, small slots h are formed, through which the tailings escape into the tail-discharge E.
The outer periphery of the tail-disk H is formed with a lip or. flange, i, fitting and mu ning in a partition, L, dividing the reel-chamber from the discharge-chamber, so that none of the fine material which passes through the cloth on the reel will escape into the tailings.
The interior of the central part of the headdisk H, inside the gear, is filled with a stationary disk, M, attached by a bracket, M
or other means to the bridge-tree which sup ports the shaft-bearing. The inner surface of this disk M is provided with a wooden ring, N, having a groove, 12, in its outer face, in which a cylindrical flange, n projecting inward from the face of the head H, runs, the whole thus forming a packing between the heads H and M to prevent the escape of .the fine meal from the reel.
earing-blocks t t, of brass or other suitable substance, will be set into the wood of the casing A, against which the projecting ring H on the head H runs, so that the re volving reel will not come in contact with the wood of the casing, but all the friction will occur upon the metal wearingblocks t, and so prevent wear upon the casing.
Attached to the inner surface of the wooden ring N is a conical wire-cloth cage or screen, P, encircling the shaft B and projecting a short distance into the reel.
P is a brush attached to and revolving with the shaft B inside of and in contact with the cage P to brush the material around in contact with the wire-cloth, as hereinafter described.
Upon the shaft 1", outside of the pinion 1. with which the gear I engages, is a chainpulley, T, connected by a chain, T with another chainpulley, T, on one of the conveyers, as 0 by which the latter is driven. The other conveyer may also be provided with a chain pulley, and the chain T arranged to run around both pulleys or gears, may be used to connect the conveyer-shafts, as shown in Fig. 1.
Outside the chain-pulley T, on the shaft I is secured a gear-wheel, U, adapted to engage a pinion, U on the shaft B. By this arrangement the revolution of the shaft B will be communicated to the shaft 1 through the pinion U and gear U, and thence by the pinion P, on the shaft 1 to the gear I on the reel, and thus revolve the latter.
By the difference of size of the gears and pinions the shaft B and beater cylinder will be revolved much faster than the reel, but in the same direction. The shaft and beater cylinder will usually be revolved about (200) two hundred times per minute, and the reel about (30) thirty or (4:0) forty times per minute.- 4 l V is a hand-hole leading into the cage P, through which the material too coarse to pass through the wire-cloth may be removed The material which is intended to be passed through this machine is fed into the cage P through the spout M", and is there acted upon by the revolving brush P, and the finer particles forced through the wire-cloth upon the beater-arms and reel. The rapidly-revolving heaters I) catch the material and throw it with considerable force outward against the cloth cage on the reel. The' finer particles are driven through the cloth and fall into the conveyers, and are thence carried away from the machine, while the coarser particles escape by the tail-spout.
Thematerial which is usually passed through this class of machines often contains coarse particles of bran, chaff, 850., and by using the wire-cloth cage P this coarser material is separated out and held back, thus avoiding the extra friction on the bolting-cloth of the reel necessary to carry this coarser material over the tail. By this means also the cloth of the reel is protected from a large amount of unnecessary wear and friction, and will consequently last muchlonger than where the preliminary separation is not made.
The action of the brush P and cage P also serves to break up the coarser particles into smaller pieces, and thus reduce the amount of work required of the reel.
The beater strips b will be provided with perforations w to out up any heavy stock which the boaters and reel-ribs fail to act upon, the holes forming just so many more sharp edges and angles to act upon and cut up the material.
The frame of the reel, as indicated, is all of iron, and will be very strong and substantial without increasing the weight to an injurious extent.
NV is a rod running through the casing A and armed with a wrapping of cloth, which rests upon the bolting-cloth-covered cylinder and wipes the adhering dust loose therefrom as the reel revolves beneath it.
A very important advantage gained by the adjustment of the reeland beater-cylinder together by the shell K is that the tail-discharge through the slots h can thereby be easily controlled and regulated, as the more the reel is inclined of course the faster will be the discharge.
Having described my invention and set forth its merits, what I claim is- 1. In a centrifugal separator, the combination of the casing A, shaft B, adj ustably mounted in the said casing, the beater-cylinder, reel headdisk H, formed with a projecting central bearing-ring, H, gear-rim I, and
flange of, reel tail-disk H having dischargeslots h h, ribs H H connecting the said head and tail disks, fixed disk M, and packingring N, substantially as and for the purpose herein set forth.
2. The combination of the casing, the bolting-cloth, the reel consisting of the taildisk H, head-disk H, and ribs H H, the fixed central plate or disk M, the packing-ring N, wire-cloth cage 1?, attached thereto, shaft B, and brush P substantially as shown and described.
3. The combination of the casing A, the shaft B,the beater-cylinder, boxes KKlsleevc or shell K adjusting-screw K set-screws d d d cl", tail-disk H having discharge-ports it h, head-disk H, having gear 1 and packingring N, ribs H H connecting said head and tail disks and having wooden strips in the angles thereof, and means, substantially as described, whereby said reeldisks and ribs may be rotated in the same direction, but at a less speed than said shaft and beater-cylinder are rotated.
4. In a centrifugal separator, a beater-cylinder comprising the shaft B, spiders G G formed in two parts and clamped to the shaft 13, and inclined beater-ribs?) b, connectingthe heads at their peripheries, substantially as described.
5. The combination of a bolting-cloth-covered reel constructed with tail and head disks and longitudinal ribs connecting the disks, a fixed central plate, M, provided with a packingring, N, and shaft B, carrying the beating-cylinder, substantially as herein set forth.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
ARTHUR HENRY VAN DUZEE.
