To all whom. it may concern.-

Be it known that I, ALVAN P. GRANGER, of

Denver, county of Arapahoe, and State of Colorado, have invented certain new and useful Improvements in Machines for Crushing or Disintegrating Ores and Similar Materials; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being hadto the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to a new form ofmachine for crushing ores and other similar materials; and it consists in the several matters hereinafter set forth, and pointed out in the appended claims.

in the accompanying drawings, Figure 1 is a sideelevation of a machine containing my invention. Fig. 2 is a central vertical transverse section, taken in the line a: x of Fig.1, looking in the direction of the arrow applied to said line.

at m of Fig. 2.

A represents a heavy revolving metal wheel mounted on a driving-shaft, A, which affords .trunnions for said whee], that are fitted to suitable bearings in a frame, (1- The wheel A has on its periphery alternating transverse-depressions andintervening prominen'ces, respectively marked A A. The undulations of the peripheral surface which form these de pressions and prominences are not necessarily of the particular form shown, though I prefer, for some purposes of the machine, that the hollows shall descend somewhat abruptly at their forward or more advanced sides, reference being had to the direction in which the wheel rotates, as indicated by the arrow on Figs. 1 and 3.

Aare flanges applied to or formed upon the sides of the wheel A and extending beyondtar-wheel and fitted to enter the depressionsv A.

It is also adapted in some suitable way to rise and fall freely as the .latter is rotated beneath it. -In the present instance theroller B is thus movably held in proper relation to Fig. 3 is a central vertical section of the operative parts, taken in the line (No model.)

D is an endless-belt elevator, reaching at its .foot into a hopperor receptacle, E, into which rides on the undulating surface of the mortar-.

wheel. It thus receives a suitable motion to,

discharge freely, (though this might be effected by itspitch,) and it also prevents the material fed by it'from escape beneath the spout.

from a point about on a level with the axis of the mortar-wheel, and is curved forward beneath the mortar-wheel to a point adjacent to the lowerend of the elevator. Thisscreenchute consists of asheet-metal bottom or board, G, side boards, g, and a screen-cloth, G", secured to ,said side-boardsor otherwise sustained at a suitable distance above or inside the bottom G. The screen structure G is pivoted at its upper end to arms 0 of the frame 0, and at its lower end rests upon a shaker, G by rotation of which the chute is agitated. The screen-cloth is arranged to deliver into the rear end, E, of the hopper E, whilethe bot tom board, G, stops short of the screen and delivers into a suitable receptacle, H.

7 G is a screen-chute,which desirably extends Adequate means for the rotation of the mor- V through which the properly-reduced particles will pass, while the portion not sufficientlyre duced will be carried onan'd delivered by the willbe descreen into the hopper E, to be again raised' and acted on by the crushingroller B, as before.

It is manifest that by providing an undulating orirregularsurface on the mortar-wheel, and thus producing a vertically-reciprocating movement of the crushing'roller B, the latter will act with a power greater than. that due to its weight simply at the points at which its downward movement is arrested or reversed. It is also manifest that by giving the mortarwheel a sufiicient speed (not great) or by making the forward en d-s of the depressions abrupt the roller B may be made to drop with considerable force against the bottom of the depressions and thus to act as a stamp in a common stamp-mill. It is this contemplated use and action (which will more commonly be resorted to) that has suggested the name above given to the wheel A. In view of such severe action of the roller B upon the mortar-wheel, I have shown at a steel or chilled plates applied as facings to the more exposed surfaces of the mortar-wheel and a continuous steel or chilled shell, B tothesnrface of the rollers 13. For holding the plates at countersunk bolts a are shown,terminating at their threaded ends in recesses a in the sides of the wheel which accommodate the holding-nuts. The casing or shell B of the roller is preferably shrunk upon the roller, though, obviously, it may be otherwise secured.

In the use of a vertically-vibrating spout, F, which drops immediately after passing the prominences A of the mortar-wheel, it is evident that the principal discharge from said spout will be into the depression A", and that the pitch of said spout may be so arranged that it will discharge only into said depressions. These various adjustments and operations and the raising of the roller-stamp and of the free end of the spout by other means than those of the prominences A as may manifestly be done, areintended to be all embraced in my appended claims.

In the understanding, also, that a wheel, A, rotating on a horizontal axis and having an undulating peripheral surface, in combination with a radially movable crushing roller, is new, I do not wish to be restricted to the particular form of the undulations of the wheel, to the details of its construction, or to the particular form of the various accessories. Neither do I wish to be restricted to the location of the crushing-roller at the exact point shown, or to the radius-bars, as the means for holding it in place while allowing the desired radial movement thereof.

I claim as my invention- 1. In a crushing-machine, the combination, with a rotating wheel mounted on a horizontal axis and having depressions in its periphery, of a crushing-roller of suitable form to enter the depressions, arranged to ride said wheel, substantially as described.

2. The combination, in a crushing-machine,

of a rotating wheel mounted on a horizontal axis, and having on its periphery concaved or curved depressions alternating with elevations whose surfaces are continuous with-those of the depressions, and a vertically movable crushing-roller fitted to enter the depressions and arranged to ride the periphery of the wheel, substantially as described.

3. A rotating wheelhaving a succession of curved depressions and elevations in its periphery, the descent of the depressed surfaces being relatively more abrupt at their advanced than at their rear ends, in combination with a vertically-movable crushing-roller fitted to enter the depressions and arranged to ride the wheel, substantially as described.

4. The combination of arotating wheel having a series of peripheral depressions to con tain material to be crushed, a movable stamp adapted to enter said depressions, and camacting surfaces carried by the Wheel, operating to lift the stamp preliminary to its descentinto the depressions, substantially as described.

5. The combination of a rotary wheel having a series of peripheral depressions to contain material to be crushed, a movable stamproller adapted to enter said depressions, and cam-acting surfaces carried by the wheel, operating to lift the roller preliminary to its descent into the depressions, substantially as described.

6. In combination with a verticallymovable crushing-roller, a wheel having a succession of depressions and elevations upon its periphery, and flanges at the margins of theperiphery, forming a peripheral trough in which the crushing-roller rides, substantially as described.

7. In combination with a rotating mortarwheel having a series of depressions in its periphery and a crushing-roller, a feed-spout which rises and falls with the surface of the periphery of the wheel, substantially as described.

8. The, combination, with the mortar-wheel and crushing-roller, of an elevator and a vertically-vibrating spout leading from the elevator to the wheel, substantially as described.

9. The combination, with the mortar-wheel, a crushing-roller, and a hopper, of elevator mechanism which raises the material from the hopper to the upper surface of the mortarwheel and -a screen arranged to receive the crushed product and to deliver the tailings back to the hopper, substantially as described.

10. The eombination,with the rotating mortar-wheel and a stamp operating on the upper surface of the wheel, of a curved screen-chute extended beneath the wheel and pivoted atits upper end, and a shaker for the chute, substantiall y as described.
