Application inea october 12, 1914.
To all whom may concern Be it known that I, JOHN WV. Baiiwniiii, a citizen of the United States, residing at WVaukegan, in the county of Lake andr State of Illinois, havel invented certain new and useful Improvements in Pulverizers, of'which the following is a specification.
This invention relates more particularly to a machine ,which is especially adapted for grinding or pulverizing grain for manufacturing iiieal or flour, although it `iiiay also be used for pulverizing Avarious other sub stances.vv
- Among the objects of this invention are to provide a piilvei'izer or grinding appara` tus/which will becomparatively Siniple and cheap `in construction, and exceedingly et fectiv n operation; to provide such a inachine in which the. wearing parts niay be f the following readilyfchaiiged 'when worn or injured; to provide a machine in which a sieve or screen niay'be readily inserted and reiiioved, and ordinary screen iiiateiial niay be used without any special preparation or construction; aiid,'in general, to provide such an iiiiproved construction as will appear inorcfully from description. taken in connection with the accompanying drawiiigsj Iiithese drawings: Figure l is a vertical sectional view ot the machine: Fig. 2i* cross section taken on the line 2-2 otl g. 1: Fig. Il is a plan view olf the lower portion of the casing. showing thefscreen iii position: and l is a perspective View ofthe iipper poi-'tion of the casing. As shown iii these drawings. 5 representsl a traine or casing'. comprising a .substanthilly rectangular bottoni portion '.l. and a seiiiicylindrical top oi' cover 'i'. For convenience in construction. the bottoni portion and top niay be divided loi'igiiudiiial'ly in the iiianiier indicated, and the sections tasteiied together liyin'caiis ot' liolts S and i). The bottoni poi'- around the upper liaiigc which engage tion is provided cover 7. which bolts serve as a means for readily securing the top in position. The fraiiie. 0i' casing 5 is opeiiat the bottom. and rests upon a base 13, which has an opening 14 therethrough, ioriiiing an outlet or discharge aperture for the machine.
per 15 may he placed under the discharge for receiving the pulverized material.

are provided with roller bearings 17' for a shaft 18. As this inachine is of the centrifugal type, and is 'adapted to run at high speedy, approximately thi-ee thousand revo-l liitions per minute, such roller bearings torniy a desirable method of supporting the shaft. A driving pulley 1t)` is iiiounteit on the shaft 18, and .is driven by a belt 20"fr`om any suitable source of power. The shaft 18 passes centrally throiifh the franie or casing and is provided with a hub 20 withinf the casing. which hub may be iliade integrally witli'tlie shaft. or niay be secured thereto in any wellltnown inanner. 'The hub 2() is provided with .three peripheral grooves 21, 22` and .23. r1`he grooves 2l aiidI 22 serve to receive the inner ends of the beater arnis 2l. These arinsare arranged iii pairs` and each pair is connected at tlieoutei' end witlfa blade or bar 25. These blades or lr .\tend approximately the full length ot'fthe interior of the machine, only a sufficient clearance distance being let't between the ends of the i hars and the inneil wall ot' the ing. The hub 2() is providedwith longiiii-dinal holes 2li adjacent to the oiiterperiphery.;tor the pivot pins 2T, which pins engage with the iniiia-'eiidsof the arins 24.
preferably provided for each pair of arins,
and these pins are held in position izlknigitie' consists oi corrugated 'plates 29, which, are
inadc in sectioiis, as shown particularly in Fig. 2. so that they may be readily insertedl and iiia'v be readily removed for replacing. These plates are held-in place b v bolts 30, and the' adjacent edges are iorined so as to overlap. vwhich also tends to hold them more securely -in position'. there will he but slight, clearance between the beaters 25 andthe inwardly projecting portions 'of the plates 29, such clearance being about Aone-quarter 'of an inch in machines which I have.constructed.I A
