CENTRIFUGAL SEPARATOR.
SPECIFICATION forming part of Letters Patent No. 260,412, dated July 4, 1882.
Application filed May 8, 1882. (No model.)
To all whom it may concern:
Beit known that I, EDWARD E. QUIMBY, of
Orange, New Jersey, have invented certain making the rim of the centrifugal-machine drum removable from the bottom of the drum, and by afiixin g to the spindle of the machine at a suitable distance above the bottom a stripping-disk, which is closely contained within the movable rim, and-hence serves to hold down a wall of starch formed against the inside of the rim while the rim is being lifted. The starch being thus stripped from the rim forms an annular wall resting upon the outer portion of the bottom of the drum, and can `then be easily removed therefrom.
The accompanying drawings, representing my invention, are as follows:
Figure lis a top view of a centrifugal machine provided with my removable rim.. Fig. 2 is a central vertical section of the same through the line a: as on Fig. 1. Fig. 3 is a similar section of the removable shell ot' the machine. Fig. 4. is asimilar section, showing the bottom of the drum and the stripping-disk. Fig. 5 is a transverse section of a portion of the bottom of the drum and rim,'and the elastic packingstrip for making a tight joint between the rim and bottom. Fig. 6 is an elevation of the machine, showing the mechanism for elevating the rim.
The drawings represent a centrifugal machine mounted upon a vertical shaft, A, the upper portion only of which is shown, thelower portion being constructed in the ordinary manner, provided with suitable bearings, and with a pulley by which the machine is driven.
The shaft A is provided with the shoulder et for the support of the centrally-perforated disk B, which constitutes the bottom of the drum. The bottom disk, B, is provided with the stout hub b, the upper end of which supports the lower end of hub c ofthe stripping-disk C. The shaft A extends through the hubs b and c, and the upper part of it is provided with the screw-thread a for receiving the nut a2.
The disks are keyed to the shaft A in the usual manner.
The stripping-disk Gis provided near the middle with the perforations c', and with the upwardly-projecting conical mouth c2. 6o
The periphery or rim D of the drum is providedatthetop withtheinWardly-turncdiiange d, the edge of which is united to the base of the conical mouth d.
The stripping-disk Gis slightlyless in diameter than the interior of the rim D, against which it fits loosely.
The bottom disk,B,is provided nearits edge with the annular groove b to receive the lower edge, cl2, ofthe rim D. The inner Wall of the 7o groove b is upwardly and outwardly inclined, andis provided with the annular packing-strip E, of elastic material, the upper portion, e, of whichi'sslightlychamfered,andprojectsashort distance above the upper surface of the disk B. 7 5 The lower portion of the strip E is thickened and the stripis sprungintoits seat; or the strip E may be permanently secured in place in any other convenient way. When the machine is set in motion the projecting upper portion of 8o the elastic strip E is pressed outward by centrifugal action against the interior surface of the rim D and makes a tight joint therewith.
The bottom disk, B, is provided near the middle with the holes F. Liquid discharged 8 5 from the interior of the drum through the holes F falls into the annular drip-trough F", from Which it is conducted by a suitable conduit to anyconvenientreceptacle. Anannular shield,
f, affixed to the hub b, projects radially there- 9o from, and catches iiuid poured into the drum through the mouth c2 and prevents it from falling directly into the holes F.
The removable rim D is provided at the top with the eyebolts or handles D', by means of 95 which the rim can be taken hold of and lifted.
In operation the starch is thrown outward and forms a wall, Gr, against the interior of the rim D, to the surface of which the starch adheres with such tenacity that some force is 10o required to lift the rim D and strip it from the surface of the starch-wall G. To effect this object I employ the elevator-disk H, provided with the dependent links 1FL/,having the hooks H2 upon their lower ends for hooking into the eyes D on the top of the rim.
The disk is elevated und lowered by means ot' the stationery elevator-screw h, which is inserted through the cent-ral perforation, It', in the elevator-disk H, and engages n female screw-thread formed therein. .The upper end of theclevntor-screw h is provided with n wormwheel, h2, engaging n worm, h3, to which the necessnrypoweris applied to operate the screw. When the rim .D is lowered into its seat und the machine is in operation the elevatorfdisk H und the links dependent therefrom are lifted up ont ofthe wey.
In operation the rim D is dropped into its seat in the groove b', und the machine being then set in motion, the starch mixture or other material to be acted upon is poured into the drum through the mouth c2 of the strippingdislr. Centrifugal action causes the mixture to press radially outward, und the heuvier solid ymetter which it contains collects against the interior surface of the rim D and forms an annular coating thereon of greater or less thickness, according to the length of time the machine is operated and the quantity of nieteral introduced into the drum. During the feeding operation, asthe mixture is fed into the drum the shield fdirects it radially out-- wurd and prevents it from falling upon the perforated parts ot' the disk B.
In conducting the feeding operation, sufcient time is given for the complete separation of the starch from the mixture which is rst introduced, and thereafter the mixture is introducedgradually, so that nothing but liquid from which the starch has been seperated is allowed to escape through the holes F.
The lighter constituents ot' the mixture form the inner portion of the annularwell of duid,
I, and the holes F are intended for the outlet 45 of fluid escaping by gravity from the inner portion of the annular well I, and also for the discharge of fluid from the drum when the mnehine is stopped.
The elevatordisk H is prevented from turn- 5o ing by ineens of the steady-pins h4, aiiixed to the horizontal frame of the machine, and projecting downward therefrom through suitable holes, h5, in the elevator-disk.
It will of course be understood that my ap- 5 5 paratus may be employed to seperate the coustituents of any mixture containing materials ot' diiierent specific grevities, and that unless the heavier or solid materiel adheres tenecicusly to therim the strippiuguisk will not be 6o required and may be dispensed with, in which cese the mixture will be filled into the drum through the mouth d" ot' the rim.
1. In n centrifugal machine, the removable 65 rim D, in combination with the rotating bottom disk, B, as and for the purpose set forth.
2. The removable rim D, in combination with the rotating bottom disk, B, and the strippingdisk C, substantially as and for the purpose 7o set forth.
3. The rim l) und the rotating bottom disk, B, provided with the holes F, in combination with the shield f, as and for the purpose set forth. 7c 4. The rim D, provided with the handles D and means for elevating the rim, as and for the purpose set forth.
