Y Application filed llctober I7, 1.8981

To all whom, it muy concern.- A Y Be it known that vwe,-I?-YR O.\T I. TURMAN and THOMAS J. HAMPTQN, citizens of the United States, residing at Los Angeles, in the county of Los Angeles, in VIche State of 7 California, have invented a new and useful Ore-Crusher,

of which the following is a specilication, reference being had to the accompanying drawings, 'forrning a part thereof, in which- 'Y Figure l is a central vertical section of our machine. Fig. 2 is a plan View taken on the line 2 2 of Fig. 3, and Fig. 3 is-an elevation of our machine.

In the drawings, A is afrusto-conical :nel tallic runner or grinding-cone (the upper portion being a frustuni of a cone and the lower. portion a larger flaring frustum) slidably mounted on the central vertical shaft B and rotating with theshaft, which may be square except in the bearings. Surrounding the runner Ais a cylindrical shell C, preferably made of cast-iron in rings of the same shape, so that' when the bottom ring becomes worn too much it can be easily removed and a new one put in. These rings are provided'with lugs C', through which bolts C" pass to vbolt thein together and to the collar D. Instead of making the shell C and collarD of separate rings they may be cast in one piece. The shell C is sufficiently strong to resistl any strain that may be put on it, and it rests' on the runner- A, the bottom having thesame pitch-as that part of the runner upon which it rests. The collar D forms a part of shell C and is surrounded by the frame E, in which are mountedl four antifrction-rolls F, which bear against the neck of the collar D. This frame has proianges E' on two sides, which rest oni cross-timbers W of the main frame W, andl its position is controlled by the threaded bolt Il, which passes through a slot in the main frame and is operated by -threaded handwheel I. These timbers W are fastened to the upright timbers of the main frame, and the frame E rests loosely upon them and has a sliding motion' thereon when the hand-wheel I is operated. Y

.I is a cylindrical ring (preferably-made of cast-iron) and has an annular race or groove J' in the under surface thereof. This ring is part motion runner engaging therewith. The ring J may 4'be' made, integral with and forni a part of the runnerA; but we prefer to make it separate,

as considerably more Wear comes on it than on the 'runnerand when it wears out it can be easily replaced with a new one. L is' a stationary annular bed-plate (preferably made ofcast-iron) having anannular groove orv race L' formed in the upperiace thereof..

M is a peripheral casing or curb lsurrounding the bed-plate and extending above the baseof the conical portion of the runner A and may be made of sheet-iron.

` N are the pulverizing-balls, which fit in the race'in the bed-plate L and ring J.

O is an apron or chute 'below' the central opening of the bed-plate L to receive the ore and convey it upon the shaking-screen P, which separates Vthe thoroughly-pulverized portions from the overtail or coarse portions. The overtail is carried to the return-elevator T by the endless screw V and is delivered by the elevator inside the casing or curb M. The screen P has a shaking motion imparted to it by the wiper-wheel R, mounted on the shaft B. S'uisa driving-pulley mounted on the shaft B,jaround which the power-belt passes to imi tothe machine. i. It willv be observed that as the runner A is slidalolylmounted on the shaft B the Whole weight of the 'runner A, shell C, and ring .I cornes on the pulverizing-balls N, thereby making them very effective in pulverizin g ore. Our machine is operated as follows: The

4shell Gis drawn out of the perpendicular, as

shown in Fig. l. lower is applied to rotate "the shaft and-ore is fed into the shell around the runner A. The shell ,C rests upon the runner A and rotates with it. This is caused partly and principally by the fact that the ore wedges by its Weight and consequent friction between the shell and runner and binds them 'l together. The top of the shell C is held in an unchanging position eccentric. to the shaft B, and thereby the ore which is between the runner and thev shell is broken into small pieces. These small pieces pass down under the bottom of the shell C, where they are stilly Vfurther crushed, and then into the casing M, where they are fed under the pulverning- IOO balls N. After the ore has been operated upon by the pulverizing-balls it Works to the opening in the center of bed -plate L and drops upon the chute or apron O, which carries it to the shaking-screen P, which separates the thoroughly-pulverized ore from the overtail or coarse portions. Ther overtail is Carried by the screw V to the elevator T, by which it is carried up into the casing M and is again subjected to the action of the pulveriZing-balls N. f f

l Having described our invention, what We claim is- 1. In an ore-crusher the combination of a rotating shaft, a frusto-conical metallic runner slidably mounted on a squared portion thereof, a cylindrical shell surrounding said runner and supported thereby, means for holding and guiding the upper portion ofthe shell in a position eccentric to the shaft, a ringsurrounding the shaft immediatelybelow and engaging and supporting the runner, and having an annular race or groove in the under surface thereof, a stationary annular bedplate having anannular groovewor race formed in the upper face thereof, pulverizing-balls adapted to fit between said groove and the annular race in the under face of the ring which carries the runner, a peripheral casing or curb extending up from the bed-plate, a chute or apron below the central opening inthe bedplate and adapted to -receive the ore therefrorn,a screen receiving the ore from the chute, and adapted to separate the thoroughly-pulverized portion from the coarscr, a wiperwheel mounted on the shaft and communicating motion to the'screen, and a return-elevator receiving the coarse overtail from the screen and redelivering it inside the casing to the pulveriZing-balls, substantially as and for the purposes set forth. I

2. In an ore-crusher the combination of a central shaft having a squared or non-circular portion, a runner mounted upon said shaft to rotate therewith, but free to rise and fall thereon; said runner comprising aconical upper portion, a larger flaring conical central portion, and an annular portion en gaging and face of substantially thesame pitch as that of the lower conical portionof the runner, Vand means for holding the upper portion of the shell in a position eccentric to the shaft, subf stantially as set forth.

3. In an ore-crusher the combination of the central vertical operating-shaft B, runner A slidably mounted on said shaft, shell O surrounding said runner having collar D, frame E having antifriction-rollers F surrounding collar D, threaded bolt I-I having hand-wheel I, ring J having an annular race J in its lower face, immediately below and engaging with runner A, annular bed -plate L having a groove L in its upper face, pulverizing-balls N fitting in said race J and groove L', casing M surrounding bed-plate L and ext-ending above the base of the runner A, chute O below the central opening in the bed-plate and adapted to receive the ore therefrom, screen P adapted to receive the ore from chtite O and `separate the thoroughly-pulverized portion thereof from the overtail, wiper wheel R mounted on shaft B and adapted to imparta shaking motion to screen P, screwV adapted to convey the overtail to elevator T, and elevator T adapted to convey the overtail into casing M all constructed and operated substantially as described herein.

In -witness that we claim the foregoing we have hereunto subscribed our names,this 10th day of October, 1898, at Los Angeles, California.
