. With these and other objects in view, this invention consists of the features, and details of; construction, separately and in combination, described in connection" with the accompanying-drawings, and then more particularly pointed out in the claims.

not perceptible until actual disruption'oc CHI'S.

which with the other necessary adjuncts of themachine, makes a cumbersome product,

difiicult to transport, and more difiicult, if

notimpossible to repair when fractured or broken. I v

In elimination of these disadvantages, the present invention consists of two side plates 1 and 2, having suitable flanges 3 and 4, on the bottom, provided with bolt holes 5 and 6, for fasteningthe same to a suitable supporting structure. These plates are tied together at one end by a shaft 7, and rod 8, carrying a spacer tube or pipe 9, and at the other end by a trunnion-10, the shaft 7, and trunnlon 10, serving additional purposes to appear hereinafter. Between and fulcrumed in said plates by fulcrum pin .or shaft 11, which also serves to tie said plates, is a lever 12,,of cross-sectionally U-shaped structure at oneend, as'seen in Fig. 3,embracing and connected by a pin 13, with a strut 14 to Iwhich reciprocatory motion "is imparted.

Generally the base in the ordinary class of through the medium of aneccentric 15,

turned or fastened on, said shaft 7, which carries on the outside of said plates, the

leys 17 and 18, respectively. The lever 12, as

seen in Fig. 3, has a double bearing on the strut, whereby the friction is reduced to a minimum andthe wearing life increased, the

pin 13, serving principally to connect the lever with the-strut. On said lever 12, is removably fastened a crushing shoe 19, by counter sunkhead bolts 19. The plane of said shoe is'ribbed orvcorrugated for a portion of its length, asat 20, and terminates in a curve 21, at a point below'said ribs or corrugations. .T he aforenamed trunnion 10, forms a pivotal support or bearing for a jaw 22, to which is arranged to be removably attached by countersunkbolts 23, a die plate 23', having a plane, ribbed or corrugated,as

at 24, and terminating in a substantially compound or ,ogee curve 25, cooperating with said curve 21,. of said shoe 19, to levigate the rockior ore. The disposition of said shoe 19, anddieplate 23, is in substantially the form of a Y,.the crushingof the rock, fed from a hopper 26, immediately above said shoe and die plate, proceeding regularly and uniformly until thejpoint be.- tween the oppositely disposed and interact; ing curves 21 and 25, is reached, where'the. final trituration takesp'lace, and the finished product discharged below said shoeanddie the crushingand breaking of the rock occurs by a reciprocatory motionof the lever, while the levigation-of the rock occurs by a grinding motion of the curv'e'of the shoe against the curve ofthe die plate, such motion being end ofthe curve .21, ofthe Shoe is virtually concentric, or nearly so, with the are described by the movement of the lever around the fulcrum point, While the rest of the curve is eccentric to such are.

Between the face of the lever 12, and the shoe 19, and also between the face of the jaw 22, and the die plate 28, is preferably interposed a lead filling or sheet, for the purpose of forming a perfect seat'for the shoe and die plate, the rough and unplaned surfaces of which readily embed'themselves into this plastic'layer. V Y

The die plate 28, normally rests a.

i V shoulder 27 on the j aw 22, which as stated,

is pivotally hung on the trunnion 10,

thus always ,connected in a pivotal manner portion of said jaw, at the rear and at api proximately a point opposite the compound curve of the die plate 28, is furnished with an integral abutment 28, which bears against a thrust bar 29, transversely disposed elongated slots 80, and held in position by cotter pins 81, or in any other suitable manl chine.

ner. Adjustment of the thrust bar 29, to regulate the degree offineness of the pulverized product, is effected by adjusting screws 82, extending longitudinally of each plate and'locked in position of adjustment by lock nuts The said thrust bar '29, may be of cast ironor any other material calculated to resist the 'strainincident upon the crushing of rocks and ores of ordinary hardness, but incapable of withstanding any excessive pressure, such as wouldresult from the operation of the lever on metal substances or objects, as steel, iron, and the like, or in fact any, not intended for treatmentby this mathe thrust bar will break, and permit the jaw to swing on itstrunnion, thus insuring the otherivital parts of the machine against breakage.
