SACRAMENTO, CALIFORNIA.

ORE PULVERIZER.

Application filed November 20,1923, SerialNo, 675,884. Renewed January 12, 1925.

To all whom it may concern:

lie it known that l. Grouch E. C. Rousseau, a citizen of the United States, residing at tltl'tlllltnl't). in the county of Sacramento, State of California, have invented certain new and useful lm n'oi'eincnts in Ore Pulverizers: and 1 do hereby declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

- s This invention relates to new and useful improvenn nts in ore treating machines and particularly to devices or machines for crushing ore which contains precious metals. One object is to provide a device of this Character wherein. the means for feeding the ore to the crusher arranged to discharge the ore directly in front of the crushing roll, and wherein a movable auxiliary crushing means is disposed between the roll and I the drum, at a point diametrically opposite the feed, to produce a more ellicient crushing action. Another object is to provide a device of this el'iaracter wherein the crushing roll normally gravitates into contact with the interior of the drum and is capable of ready self-adjustment so that should too much ore h delivered into the device the roll will rise without allccting the driving thereof.

A further object. is'to provide a crushing roll wherein the periphery is formed of readily removable sections having large opcrating faces, which permit easy and quick. replacement. of any portion when worn.

Other objects and advantages will be apparent from'the following description when taken in connection with the accompanying drawings.

In the. drawings:

Figure. 1 is a side elevation of an ore crushing nnu-hineimade in accordance with the present invention.

Figure 2 is a vertical sectional view on the line 2-2 of Figure 1.

Figure 3 is a vertical sectional view on the line 3--3 of Figure 2.

Figure 4; is a horizontalsectional View on the line -1---,! of Figure 2.

Referring particularly to the accompanying drawings, the supporting base for the ore crusher consists of the cementblOCliS 1O. 11, 12, andlii. The hlooks and 1 are of the same height. and mounted on the upper an of eat-h of thcsc hloclts is a bearing block 14, which supports the, trunnions of the drum supporting and guiding rollers 16. On the block 12 are the bearing blocks .cul'cd a second ring 21, having a ciroumfer ential series of gear teeth 22 which mesh with the teeth of the gear 19, and by means of -which gear 19 the drum is rotated in the direction of the arrow in Figure 3. The-inner face of the ring 20 is formed with a circumferential ly extending groove or channel 23, to which reference will be made later. On the upper face of the block 11 there is also mounted a bearing block 2% which supports the guiding rollers 25, said rollers also being arranged to support the drum. In the upper face of each of the blocks 10, 11, 12, and 13, there are formed the grooves 26 to receive the lower portions of the rollers. It will be noted that the center of the peripheral face of the outer ring 21, on which are formed the teeth 22, is in the form of a. circumferentially extending rib 27, which produces the circumferential ledges or open-sided grooves 28, at the opposite sides thereof. It is within these grooves that the guiding and supporting rollers 16 and engage. Secured to the opposite sides of the rings 20 and 21, are the'disks 29, each having a central opening 30 through which theore to be crushed is fed. The peripheral edge. portions of these disks 29 extend beyond the periphery of the ring 2-1 and lie against the outer side faces of the rollers 16 and 25, whereby to form the outer walls of the grooves or channels 28, to retain the rollers and drum in proper relation to each other. Formed in a circular series in each of the disks 29, adjacent the periphery thereof and inwardly of the inner face of the inner ring 20. are the elongated openings 31, within each of which is secured 'a screen 32. Movably mounted on the disk, at each of the said openings 31, is a cover plate 33, arranged to he swung into and out of covering relation to the opening.

Disposed within the drum is a crushing wheel, designated as a whole by the numeral 84, and this wheel includes a huh 35, in the form of a disk; a rim 36; and the-spokes 37, the latter being secured to and extending between the hub and rim, as clearly seen in Figures 2 and 3. Engaged on the periphery of the rim 36 are the segments 38, each having a bifurcated lug on its inner concave face, at 89, for straddling engagement on the rim, a bolt 40 being engaged through the lug and rim. By this construction a worn segment may be easily removed and replaced when it is necessary. The hub 35 is fixed on the shaft 41 which extends transversely of the drum and projects through the openings 30 of the disks 29, said shaft being preferably located normally at the lower sides of said openings. Secured to the block 11, and extending vertically at the opposite sides of the drum, are the longitudinally slotted uprights 42, the slots 43 of which have the slidable bearing blocks 43 therein, and-which.blocks rotatably support the end portions of the shaft 41. One end of the shaft 41 is provided with a universal joint memebr 44, as seen in Figure 2, and supported in the upper end of an upright 45, which is mounted on the end of the block 11, is a drive shaft 46. On the inner end of this shaft 46 the sleeve portion 44,, ,of the universal joint 44 is slidably keyed or splined, while on the outer end of the shaft,is fixed a gear 47, meshing with a gear 48 on the adjacent end of the shaft of the gear 19, whereby power applied to the shaft of the gear 19 will be transmitted to the shaft 41, to rotate the crushi wheel 34, in the direction of the arrow of Figure .3", while at the same time the drum will be rotated. The gearing 47 and 48 is such that the-' 'crushing wheel will rotate at the rate or ratio of 12 to 1, with respect or relation to the drum. The universal joint 44 permits the wheel 34 and its shaft 41. to rise and fall without interference with the gears 47 and 48. Secured to the outer face of each disk 29, outwardly of the series of openings 81, is an outwardly flared ring or flange 49,

which serves toguide the pulverized material away from the side of the drum, as said material flows out through the screens.

Disposed above the drum is a hopper 50 for containing the ore to be crushed, said hopper being supported on the uprights 51. The bottom of the hopper is provided with a pair of downwardlyextending discharge spouts 52, which lead into the openings 30, and connect with the troughs or chutes 53,

said chutes extending downwardly and forwardly to points over the space betweeen the wheel 34 and the inner face of the ring 20,

so that the ore will be deposited at the proper position to pass beneath the crushing roll, as will be readily understood.

Loosely disposed between the crushing wheel 34 and the innerface of the ring 20, at a point approximately diametrically opposite to the point of reception of the ore to be crushed, is a triangular, block 54,

which normally gravitates aga'nst the wheel and ring so that the materia which has been crushed between the wheel and ring the rim of the drum, and a floating crush ing element between the wheel and rim at a point opposite the point wherein the ore is fed.

2. An ore crusher including an outer rotatable drum and an inner crushing roll, said roll including a rim, and a plurality of segmental blocks each, having a pair of spaced lugs straddling the rim and secured removably thereto, the working faces of the blocks forming a continuous crushing peripheral face. j"

-3. An ore crusher including an outer rotatable drum, an inner crushing roll dis- "posed within the drum and gravitatin into contact with the interior of the drum, and a wedge between the crushing roll and the interior of the drum and cooperating therewith for crushing ore.-

4. An ore crusher includin an outer rotatable drum, an inner rotatable crushing roll gravitating into contact with the inner circumferential face of the drum, means for of the drum, and an auxiliary crushing means between'theperiphery of the roll and p the said circumferential face at a point diametrically opposite to the said feeding means.

In testimony whereof, I aflix my signa' ture, in the resence of two witnesses.
