Be itknown thor I, iViLnnmr LornAR YELTEN, n citizen of the Germain Empire, residing at- Kornthal, in the Kingdom of 'rtemberg, Germany, have invented certain new and useful lmproveinents in Stone- Crushers; and 1 do hereby deehire the following to be a. fuil, clean' und exaet description of the irmfntion, such as will enable others shilled in the art to nhieh it' uppertains to make und ise the same.

This invention relates to ore and |stone crushers, and has for its princ'ipal object to provide 8. crnsher of simple and economical conetruetion and which may he readily adjusted to very the size of the prodnet.

A fnrther ohjertof the im'ention is to pro-v vide the bron king-juws with intert'hnngenhh' and reversihle fnee-plzites having teeth so :irranged as to eih'etiveiy erush the material Without permitting large Stones or hnnps to be forued up'vfard ns the ino're toward each-other.

A. still further object of the invention is to so Inount and arra-nge. the nim-'able jmvs that each may move. tlownward during` the ernshing movenient and npward ns the faws separat-e. i

Vt'ith these and other objects in view 'the invenon consists in the novel construction and ari'nngement of parts hereinafter de- Seribe'i, illustrated in the drawings, and partienlaf'ly pointed out in the appended chtims.

in the necompanying drawings, ii'igure lis av sidel eleval ion of :i stone-crusher construeted in amfordance with the invemion. is a trzinsverse s'-f.'tim:il view of the. same in. the planie of thel main sheft.

At-the center of the shzlft is un eecentric g, through which movenient is inx'parted io the movable jaws of the ornsher.

I At the inner wall; of the end 'portions of, the frame are arranred detaehsbl? and int-er' zhzmgenhle face-plama 1:. having eonvex operziting-zu'es whieh are-provided with horizontnl r'r'ws of teeth.

the present instnnne the two central rows of teeth i) are made higher than the end rows, the smaller teeth 'r' ni the hottoxn eii'ecting the iiner crnshing, and when necessary the plate-s may he reversed in order to bring the small tevth of the top row lowrmos't.

The upper lportions of the two movable jaws d d' are pivotzill)v connected bye pin t. and the top of jaw (l is enlarged and provided with an opening` for the reeeption of the. euremric g.

those of the plates b-thfit is to say, the centre! reivs of teeth being of greater heightthan the end rows. The face-platefs are held in position by \'.'edge-shaped hurs e and are also reversihle and interchngeable.

The lower portions` of the inner side Walls of the frame :u'e provided 'with spuced guideribs o, arranged to receive transversely-disposed bn'rs n, and between these bm's is an eccentrie or cam p, ('zn'ried by a shaft that extends through hearing-openings in the frmne and'carries nt oml end a level' q, which may be moved over a locking-(padrant 1' for the purpose of turning the van' p. and thns adjusting the distnnce 'between the hars 'n.

The lower portions of the inner .faces'of jawa (Z d' are provided with parallel recesses m, :md :1 plnrality of similar reeesses is formed in each of the har n.

5. In a erushing-mill, the combination with a frame, of a shaft supported at the upper portion of the frame, an eccentric on said shaft, a pair of fixed jaws at the ends of the frame, a pair of movable j aws pivoted together at their upper ends, one of said `aws having an opening for the reception of th siidably-mounted hars in the lower portion of the frame, the outer face of each bar being provided with a plurality of transverse recesses, a cam arranged between the two bars, a shaft carrying the cam 5 a lev er for Operating said shaft, link-plates extending between the bars and the lower portioiis of the movahle 'aws said iaws havin reeesses'for the rece 7 1 tion of said link-plates, and spring-oressed rods tending to .hold the inovable jaws in en- {,'a ,'en1entl Wit-h said links.
