U ITE STATES PATENT QFFIC WILLIAM ROWLANDSON, or LIVERPOOL, ENGLAND.
CENTRIFUGAL MACHINE.
SPECIFICATION forming part of Letters Patent No. 655,015, dated July 31, 1900.
Application filed February 8, 1900. serial No. 4,496. (No model.)
To all whom it may concern.-
Be it known that I,WILLIAM ROWLANDSON, consulting engineer, asubject of theQueen of GreatBritain, residing at Liverpool, county of Lancaster, England, (whose full postal address is 132 Boundary street, Liverpool,) have invented certain new and useful Improve= ments in Grain-Drying Machines, of which the following is a specification.
This invention has for'its object a centrifugal machine specially adaptable for separating liquids from granulated substances. It is best described by aid of the accompanying drawings, in which- Figure l is an elevation, partly in section; Fig. 2, a plan, also partly in section.
In the drawings, A is a vertical shaft, and B an annular disk having a sleeve hkeyed on shaft A. V
O is a centrifugal cage attached to plate B and covered on its inner circumference with foraminous material, as perforated steel 0,
though perforated zinc or other metal or even wire-gauze will do. I
D is a stationary casing imperforate at the sides, but having an opening (1 and pipe D for the escape of liquid and a flange d, extending upward and carrying the step or deep bearing d of the shaft A. This inner cylindrical casing D rises to a level with the rim of the open-topped cage and is turned inward at its upper margin, so as to fit to the rim on four in number and made sharp at the top, so as to prevent any grain lodging on them.
J J are other spacing-blocks for uniting together the casings D and E above and having bolts (not shown) passing through them and the casings to hold them firmly together.
. casing c.
K is the upper bearing for shaft, supported in the stationary top frame L of the central chamber.
.The drum F, the cover L, and the casingE are all firmly attached together by bolts. (Not shown.) 7
M is the spout for thepurpose of feeding the wet material into the drum.
The mode of action is as follows: The cage being set in rapid motion by means of a band on pulley H or other suitable driving device, wet stufi is admitted by spout M, which falls on the plate B. This by centrifugal force passes under the lower edge of the stationary drum Fand is thrown against the perforated The liquid portion flies out into the casing D and escapes through the hole (1. The solid portion comes in contact with the flanges f and rides up them until it passes away cen trifugally over the inturned upper margin of the casing D and escapes at G. The water which falls into casing D is prevented from splashing into the bearings of the shaft A, being stopped by the projecting sleeve (1.
I declare that what I claim is-- 1. In a centrifugal machine, the combina tion with the cage, of an internal stationary drum F hung rigidly from a stationary sup= port above and dipping into the cage, and having a spiral flange f thereon, substantially as and forthe purposes described. 2. In a centrifugal machine the combina= tion of a rotating cage, a stationary spiral guide fixed in and close" to the periphery of that cage and an outer easing into which the spiral guide delivers the solid material, substantially as described.
3. In a centrifugal machine, the combination with an outer, fixed casing, and an inner, fixed casing of less diameter than the outer casing, whereby an annular delivery-outlet is provided between them, of a rotative, foraminous cage within the inner casing, said cage and inner casing being both open at the top, and the cage fitting snugly at its top within the inturned rim of the inner casing, and means within the cage for automatically elevatin g and discharging the solid material,sub= stantially as and for the purpose set forth;
4:. In a centrifugal machine, the combina tion with the outer, fixed casing E, and the inner, fixed casing D, of less diameter than ICC the outer casing, withadischarge-outletGbemy name, this 23d day of January, 1900, in tween them, of the foraminous, rotating cage the presence of two subscribing witnesses. within the casin D and the fixed, pendent drum F, within th cage and having a spiral I ROWLANDSON' 5 flange on its outer face adjacent to the wall Witnesses:
of the cage, substantially as set forth. G. O. DYMOND,
In witness whereof I have hereunto signed I ALBERT O.- B HENRI.
