UNITED STATES application tiled January ltlfttt.

To all 'who/m. t may concetti:

lle it lniown thi.y l. Pani', Panties, a citi Zen oit the United States., and a resident olf Aliouisvillej county of del; rson, and ltate oi" lientnclry7 have invented a certain new and iasetul Crusher.; and l do hereby declare that the ltollowino1 is i. lull. clear, and enactdescriggition tliereoii, i'eterencc beine; had to the accompanying drawings, in which. like nu- .morals refer to like parte.

This invention relates to in'iprovenicnts in crushing machinery, and in particular is diw rected to a single unit erusher tor reducing .large masses ol large six/.e material to a smaller size. The Crusher is particularly adapted to work upon coal and reduce large sizes thereolf' to a smaller and suitable sise :tor use in a lurnace. equipped with power or hand operable stoking;` machinery.

the chiet object of the :invention is to construct a erusher oit the general character described which will reduce large sizes ol coal and similar material to the desired sin iup; thereofj `with increased capacity or discharge.

nnother object ot the invention is to oon- Jt a ciiusher in such a manner that by rejlilacing external and detachable parts, the crushing,1 action. may be inodilied to the various niateii'ials upon which the Crusher to worlt, thus insuring,- stability and rug gedness in the Crusher construction while permitting` the same to have a wide range oit' adaptability.

Une feature of the invention consists in pivotally mounting a curved crusher plate upon an eccentric mounting and oscillatingI it thereon to cooperate with a relatively stationary breaker plate so as to give said Crusher plate a combined oscillatory and circular movement l'or crushing)` or reducing,l lthe material acted upon in an improved. manner such as will secure reliet oi pressure and result in greater speed or capacity and uniformity in sizing.

Another feature of the invention is the association ol an eccentrically operable reciprooatory means tor oscillatingl or rocking` lthe eccentrically and pivotally mounted curved crushed." plate and operating both tti-oni. a common source ol? power, and so connectingg both operating means with the source of power and each other that the relative movement between the two may be varied within a relatively wide range to perlll).

Serial No. 6153384.

init a diliierential movement between the lower ci' discharge end ol the Crusher plate with respect to the breaker plate tor ei'l'ect ingr the desired action oi the crushing, sizingl and reliei portions of the crusher plate for accompl'slungw the results above mentioned.

Mill a further :leature ot the invention consists in the arrangement ot the curved crushing surface oli the Crusher plate with respect to the ijiosition oft the eccentric mounting;v upon which it is pivotally suzpported, 'whereby the desired. crunching, chewing and discharge action may be obtained.

The full nature oit the invention will be understood troni the accompanying drawings and the following description and claims:

ln the drawings, Figure i is atop plan view of a crusher embodying' the features oi the invention. Fig. E?, is a side eleva tional view olfl the saine, the cooperating Crusher members being shown in dotted lines. Fig. 3 is a longitudinal sectional view ot the crushing; parts with the operatiniif; mechanism in one position. Figs. ll.) 5, G and i' are sectional views ol' the curved crus'lier plate, the driviini` mechanism and a portion oit the breaker plate associated therewith.J each o'i said views showing said. dri vingmechanism in different positions. Fig. il is a modified torni showing,` an adjustable type oit ,link and eccentric driving mechanism for imparting the oscillatory movement to the Crusher plate.

ln the drawings there is illustrated a crusher which :is oit substantial and simple construction and the saine includes a pair of side :lr nies l0 and ll coinplenientarily lforined j. suitably connected together at the ends. il. hopper is itormed by two parallel plates l2 secured to the side trames )lo ineans such as the bolts and nuts f ie other two sides ot the hopper are by the crushing; plates.

l erefn the relatively stationary breaker plate is pivotally supported at its upper end by :i pin il, and said plate has a curved portion and a relatively flat or plain portion iti which terminates in a detachable llat plate lll'. The plate 17 is detach able to peinit replacement when the saine becomes worn. The hingedly supported relatively stationary plate is provided at each end with side walls or webbing 18 by sui lll.

' frames.

which terminate in bearingsl 19 that receive a pin 20. The pin 2O adjacent each end supports a rod 21 which extends longitudinallythrough t-he side framing oi' the machine and terminates beyond the saine. Upon each rod 21 is positioned a coiled spring 22 which bears at one end upon the side frame and at the other end upon a washer 23 retained in adjusted position by ay pair of lock nuts 24. All ot' the toregoing. is either identical. or substantially similiar to thatshown in the co-pending application, Serial No. 495,048. The crusher plate in ythis invention is constructed in substantially the saine manner as that described and villustrated in the co-pending application hereinbet'ore mentioned, and said Crusher plate comprises a curved base pla-,te 25 having the side walls 26 which terminate in a bearing portion Q7. The bearing cap 28 associated with each bearing 2T completes the bearing support for the curved base 25. Upon the curved base plate 25 is suitably secured a plurality of facing plates 26, and` said 'facing plates 26, whichA are detachable, detachably support a plurality of di'ierently sized crushing and cutting teeth 27 and 127. rlhe lowermost portion, of the curved base 25 is faced with a lair of detachable plate members 28. Said plate members 28 formy an arcuate surface having a center corresponding with that of the shaft Q9. The sha't't ZQYthns pivotally supports the arcuate as well as the curved crusher plate construction. Herein, see Figs. 2 and 3, the side traine is shown provided with a bearing 30 adapted to receive the non-eccentric shaitt or supporting portions 31 of the shatt 29. The supporting portions 31 ofthe shaft 22) are larger in diameter than the shaft 29.v Ln this manner the pivot or shaft 2Q may he readily ren'ioved t'i'om the machine through the bearing openings in the side As. shown clearly in the several views the shaftQQv is eccentric to its bearinggportions31, and thus when the bearing?` portions 31 are rotated in iiXed bearingsfthe eccentric shaft provides an eccentric pivot for the concentric and curved crusher plate.v The shaft. 31 is extended upon opposite ends and one end carries a pulley1 wheel'32 by which power is applied to the machine. The other end oit the shaft. 31v carries a gear 3o which is adapted to mesh, with another gear 133 upon a shaft 3', lhe shaft 34 Vis rotatably supported in the bearing blocks and 37 suitably seeured to each other and to the framework ot" the machine.,

Positioned midway between the bearing blocks 36, and4 3T and upon the shaft 34; is a. circular eccentric-,38. The eccentric 33 is. rigid,V with the shaft and rotates therewithV Adjacent the eccentric 38 is a link whicl'i terminates in a bearing portion asstaviated with which is another bearn'tion or cap 'fl-ll to surround the eccircular member The base inemintermediate its ends is provided 'tl' a pai;l ci ears which pivot-ally supi and said pin supports the "tional movement ot' the shait 31 irmed into reciprocatory moveor the pin fili through the eccentric Uhr; l'LlCtlO-ll.

.i the shafty 3l, which is an extension ot this eccentric shaft 25), and shaft il are geared together, there is a speed relation between the reciprocatory movement imparted to the curved crusher plate and the eccentric movement, due to its eccentric pivot. By the use o1" a hunting tooth in one oit the gears 33 or 138, a non-repeating speed reiation can be obtained ilf desired. This construction will reduce wear on the gear teeth. lt will be ap )arent that by changing the gear ratio, tliere will be a change in the relationship of the pivotal movement about the eccentric mounting and ine movement oi the eccentric center. By this arrangement, the machine is adapted to crush material of dili'erent kinds to substantially the same size, since the throw olf the eccentric rod or link 39 is the same in ail cases for all. gear changes. Thus a. i .aerial which requires repeated haimnering, rolling, or crushing betere rupture., will be crushed by the machine when the rate oi i. procation ot the link 31) is relatively high. it the material is relatively sott or easily reduced, the rate of reciprocation oi the link 3%) may be very low compared with the movement oll the eccentric pivotal mounting.

In Fig. 8 there is .illustrated an extension and modified form of the particular meansy for oscillating the crusher plate upon its eccentric mountings. In this modification the link 139 is adjustable in length and in addition the amount of said adjustment may bevaried by interposing an eccentric collar 137 between the eccentric 138 and the shaft 134. By shifting the position of the collar 137 relative to the shaitt 13st various amounts of eccentricity can be obtained. This last 7ariation can be obtained by other equivalent means, not shown, and the aforesaid variation varies the amount of oscillatory movement of the plate The first mentioned adjustment merely determines the initial and final positions of the plate 25 upon the pivotal support. A combination of both adjustments willv provide for considerable variation in the oscillatory movement of the plate Q5 independent of. any gear ratio change as heretofore explained.
