'1 '0 all whom it mayconcern:

Be it known that I, GEORGE A. STaN'roiI,

provide an extremely strong and rigid ore crusher which will be formed of a few simple parts that will not easily getout of order and may be manufactured at minimum cost. 5;} I

With the above objects .vi tion consists of certain novelaf struction and combination f p after fully described andj icl'a'imed understood that variOtiItiO'difi'ct n made in, the minor details of con'st-iiu within the scope of the'appended claims.

A pair of stationary upwardly and outwardly iiiclined castings 11 for' journaling the crushing and ,pulverizin'g rollers on A -one side of the machine are secured to the -ll s,"ieach castingmaving an attaching-."foot hichisrigidly sec'ur'edto the related'bcd bolts 13. A "pair of posts lfljare' se-- to the outer faces ofjthe eas h post being fixed 'to the rel thef'ang which knee is rigidly 'securedjin-fz'p a castings 11 are further rigidly braced'by means of pairs of inclined braces 17, each i which cbyi the bolts 13 and 15 above"mentioned..-1 'Thej pair being secured at the lower ends to a related bed sill by a pin 18, and being s ecured at the upper ends to a related post by a pin 19.

Pivotally attached to the castings 11 and inclining oppositely therefrom are castings for journaling the crushing and pulver izing rollers on the other side of the machine, these castings being adjust-able with respect to the castings 11 within certain limits aswill hereinafter appear, .in order .tovary the space between the coacting crushing and pu'lverizing rollers to adapt] the machineto operate upon various ores.

able openings in the castings 20 and through hinge ears 22 on the castings ll -and forms a a pivot for the castings 20. The castings 20 are provided each with an extension 23 which extends below said pivot and bears upon the outer face of the related bed sill 'for a purpose which willpresently be-described. .A pair of posts 24 are secured to --.the outer faces of the castings 20"ea'ch post being rigidly fixed to the related "casting by ,bolts 25 and being further fixed to the related. extension 23 by means of bolts 26.

A transverse shaft 21 is passed through suit -Forfned in each extension 23 is an arcuate slot 27 having its center of curvature c0- "inciding with the axis of theshaft 21', and

through each slot and a si iitableope iiing in I therelated bed sill a stopbolt 2 81 s, passed. It, is now clear that when the castings 20 are rockedin either direction on their pivot slilaft 21, the bolts 2 8.will contact with the withinwhich limits of movementthe cas'tings 20 may be adjusted to vary the space between the rollers carried by these castings and the rollers carried by the stationary Scastings 11, to enable various ores to be most efi'ecti'vely operated upon. I a

f Journaled at the ends in,--the-stationary castings 11 is a series" of equal-ly spaced apart superposed rollers substantially equal rollers 29, 30 and 31 of the stationary casting in operating upon the ore. The upperclogging.

most rollers 29 and 32 of both series are known as the first set of crushing rollers and vthese rollers are corrugated spirally longitudinally of their length, and are rotated toward each other, whereby a continual grind or crush of the ore is effected without The intermediate rollers 30 and 33 of bot-h series are known as the second set of crushing rollers and these rollers are also corrugated spirally longitudinally of their length and are rotated toward each other, and it will be noted that by virtue of the divergency of the stationary castings 11 and adjustable castings 20, the second set of crushing rollers are disposed nearer together than the first set, whereby the ore which has been crushed-by the first set into irregular fragments is crushed into still smaller fragments by the second set of rollers. The lower rollers 31 and 34 of both series are known as the pulverizing rollers and these rollers are rotated toward each other and have their cylindrical surfaces smooth, and by virtue of the divergency of the stationary and adjustable castings, the pulverizing rollers normally contact with a resultant pulverizing of the ore during its passage down between these rollers.

Any preferred means for actuating the series of rollers carried by each pair of the castings may be employed, but preferably the series of rollers are actuated by related trains of gears 35 and 36 which are driven by a common driving gear 37 carried by a stub shaft 38 which is j ournaled in a bracket 39 carried by one of the ground sills 10, which shaft in the present embodiment of the invention. is illustrated as being driven by a sprocket gear 40, it being understood that any preferred driving means may be employed without departing from the spirit of the invention.

For adjusting the adjustable castings 20 and locking the same in-adjusted positions, I provide a pair of links 41 which extend along the outer faces of the posts v14 and 24 .near the upper ends of the latter, each link being pivotally connected at one end to the related end of the above mentioned pin 19 carried by the post 14 of the adjacent stationary casting l1, and having a longitudinal slot 42 near the opposite end which slidably receives a block 43 which carries a pin 44 that is secured to the related post24 of the adjacent adjustable casting 20. A feed screw 45 carrying a hand wheel 46 is threaded through the end of the said link 41 and is engaged at the tip with the outer end face of the said block 42. Upon the feed screws being retracted, the weight of the adjustable castings 20 causes the castings to follow the feed screws with a resultant spac ing apart of the crushing and pulverizing rollers to a greater extent than normal, and conversely upon advance of the feed screws nected at the upper ends to the related pinv 44 and being connected at the'lower ends by a plate 48 which is engaged with a rack bar .49 carried on the top face of the related bed sill. The two pairs of props 47 are in the nature of strong rigid rods capable of with standing the severe shocks and jars attendant upon the crushing and pulverizing of the ores during passage through the rollers.

A hopper 50 is secured to cap rails 51 and 52 which connect the tops of the posts 14 and 24 respectively, this hopper being designed to discharge its contentsinto the space between the first crushing rollers the ore feeding down by gravity between the rollers to the second set of crushing rollers and from thence to the 'pulverizing rollers as ordinary. The hopper is braced on one side by inclined braces 53 that are con-' nected to the posts 14 and is braced on the opposite side by vertical braces 54 that are connected to the bed sills 10.

For housing the rollers, both posts 24 are connected by end walls 55 and both posts 14 are connected by end walls 56. The posts14 and 24 on each side of the machine are connected by side walls 57 and 58 respectively. The casing thus formed positively prevents escape of the ore until it has passed through the pulverizing rollers.

From the above description it will be seen that I have provided an extremely strong ore crushing and pulverizing machine,

which machine may be adjusted within cerores, and furthermore that the device is formed of a few simple parts which will not easily get out of order.

1. An ore crusher including pairs of upwardly divergent bearing castings, coacting rollers carried by said castings, means anchoring one pair of said castings stationary, means mounting the other pair of said castings for limited pivotal movement relalively to said stationary castings whereby the angular relation of said pivotal castings relatively to said fixed castings may be va: ried, means for locking said pivotal castings in adjusted positions, and means for-actuating said rollers.
