Speciaton of Letters Patent.
Patented Oct. 22, 1907.
To all whom it may concern:
Be it known that I, GEORG HILLER, engineer, a subject oi Saxony, Germany, residing at leplitz, Bohemia, Austria-Hungary, have invented certain new and useful Improvements in Silting-Nlachines, oi which the following is a specilication, reference being had therein tothe accompanying drawings.
This invention relates to improvements in siftingl machines, and has for its object to improve the construction and increase the el'liciency aud utility ol devices ol this character.
With this and other objects in view, which will appear as the nature o the invention is better understood, the invention consists in certain novel 'features of construction as hereinafter shown and described and specitically pointed out in the claims.
ln the drawings lorming a part oi this application, iu which corresponding parts are designated by the saine reference characters, is shown the preierred embodiment oi the invention capable of carrying the same into practical operation and in the drawings employed i' Figure l is a sectional elevation ol the invention in its simpler lorm. Fig. 2 is a transverse section on the line 2 2 of Fig. l. Fig. 3 is a sectional elevation el the improved device connected with a mixing machine ol approved iorm. F ig. lis an enlarged sectional detailed view of a portion oi the improved device.
ln its simpler iorm the improved device comprises a casing having an imperiorate upper portion l. and a perforated lower portion 9, the imperi'oratc portion having a dome-like top l0 through which the leed spout ll is extended. A shaft 7 extends through the casing 115) and is supported by suitable hearings, and fitted to be rotated by any suitable means, but as the rotating means lorms no part of the present invention it is not shown.
Attached to the shalt 7 within the casing l9 are two spaced members consisting of hubs l2, 13 having radial arms 5, (i, the radial arms 5 connected at their outer ends to annular conical plate 4 with its inclination inwardly and downwardly, and the arms G connected by their terminals to a conical annular plate 3, the inclination of the latter being outwardly and downwardly, as shown in lligs. l and 2. Attached to the shaft 7 between the hubs l2, i3 are a plurality oi concaved circular plates 8, and extending between the plates 3 and 4 are curved wings 2, the wings being spaced uniformly apart as shown in Fig. 2. The outer edges ot the wings extend nearly to the inner face oi the perforated portion 9 oi the casing. By this means the material fed through the spout ll falls upon the l upper plate 4 and passes from thence between the arms l 5 and upon the plates 8 in succession, and is thrown into the spaces between the curved blades 2 and by them thrown forcibly against the screened sides 9 and discharged thence into 'suitable receptacles. The shalt 7, beingrrapidly rotated produces a vigorous action upon the material and throws it iorcibly against the screen, causing it to pass through the same, and thus be finely divided as will be obvious. The material in ialling through upon the central portion o the casing between the arms 5 and 6, and being acted upon by the concave plates S, the coarser particles iall directly upon the arms G and are discharged at the center oi the machine, while the liner particles only come in contact with the wings or blades 2. The arms 5 serve an important purpose in assisting in breaking up the material and disposing it in better condition ier the action oi the plates 8 and the wings or blades 2. The rapid motion o the blades 2 creates a strong current or suction through the machine, and thus materially aids in the action. The centriiugal force oi the device is also an important fea-ture, as will be obvious,
'lhe screen material 9 may be of any desired size oi mesh to enable the machine to be employed ior the separation oi material oi different qualities or sizes.
The machine is preferably constructed entirely oi metal but may be o any other material required.
ln Fig. 4 the improved device is shown associated with a mixing machine oi improved construction, which serves to thoroughly mix the material before it is inducted into the sifting machine, but as this mixing machine is the subject oi another application tor patent, it is not further described.
Having thus described the invention, what is claimed as new isz- A11 apparatus of the class described comprising a cylindrical casing,- having an upper imperforate portion and a lower perforated portioln'a vertical shaft mounted for rotation through said casing, hubs spaced apart upon said shaft within said casing and each provided with a plurality ot' radiating arms, an annular conical plate connected to the terminals ot the arms ot' the upper hub and inelining, inwardly toward the center of the machine, an annular conical plate connected to the terminals ot the arms ol' the lower hub and inclining outwardly toward the periphery of the machine, a plurality of curved wings extendingl between said annular' conical plates, a plurality of concave plates spaced apart and connected to said shaft between said hubs, and means for feeding material upon the upper of said conical plates In testimony whereof I alix my signature in the presence of two witnesses.
GEORG HILLER.
