JAMES H. KINKEAD, OF RENO, NEVA DA, ASSIGNOR OF ONE-HALF T .PIERCE EVANS, OF SAME PLACE.

ORE CRUSHER AND PULVERlZER.

SPECIFICATION forming part of Letters Patent No. 277,578, dated May 15, 1883.

Application filed August 15, 1852. (No model.)

Reno, county of iV-ashoe, State of Nevada,

have invented an Improved Ore Crusher and Pulverizer; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a new and useful improvement in ore crushers and pulverizers of that class in which a rotary crushing disk or plate is revolved against a stationary one, whereby the ore is ground between the two.

My invention consists in peculiarly ribbed or dressed crushing-plates, which will be hereinafter particularly described, and set forth in the claim.

The object of myinvention is to furnish an elfective and simple means for crushing and grinding ore.

Referring to the accompanying drawings,

Figure 1 is a perspective View of the entire mechanism. Fig. 2 is a perspective view of one of the corrugated dies; and Fig. ijis a longitudinal vertical section ofthe en tire machine.

A represents a foundation. B1; are standards, to which is bolted a circular stationary plate or muller, 0, having an outer rim, 0. It is concave upon its inner face, and is provided with a hopper,'1), upon its back, which delivers its contents through an aperture in the muller.

E represents a fiat disk or rim with an open It is bolted to the inner face of the muller O.

F is a concave crushing-plate, secured upon the inner face of the concave muller O and within the disk E. Upon the face of this plate F are a number of ribs, 1, radiating from the center and increasing in width toward the circumference. The outersurfaces of these ribs are flat, and continue the plane of the disk E, as shown in Fig. 3. Theucethey slope to the center. Their edges also are beveled. Between the ribs are formed depressions a, in one of which an aperture, V, is made correspondin g with the aperture through the muller 0, with which the hopperD communicates.

0 represents a muller similar to 0, having upon its face a flat disk, E, and a concave crushing-plate, F, provided with ribs f, similar to those marked f upon plate 1'. \Vhen the two. mullers are brought together, as best shown in Fig. 3, the faces of the disks E and E are in close proximity, and also the flat outer surface of the ribsfandf of the crushing-plates F and F, while, on account of the concavity of the two plates, an interior space is provided with which thehopper l) communicates. The muller O is provided with a hub, a, into which the end of a shaft, G, is fitted.

H H are standards having boxes 71 It, in which the shaft G isjournaled.

I is the driving-pulley, and J a fly-wheel.

The shaft G is so fitted in its bearings as to be capable of alongitudinal adjustment, which is accomplished by means of a set-screw, g, and ajam-nut, g, at its outer end, as shown.

K represents a casing or hollow disk, bolted to the flange 0 of the stationary muller G, and inclosing the crushing-plates and rotary muller, as shown. It is provided with a discharge, 0.

The operation of the device is as follows:

.Ore is fed in at the hopper D, and passes through the stationary inuller U and the openingV in the crushing-plate F into the central space formed by the concavity of the two.

crushing-plates. Power is applied through suitable belting to shaft G, which revolves the muller C. Its crushing-plate F crushes the ore betweenits ribs f and those of plate F, and its disk E grinds or pulverizes it against disk E. The ore finally is discharged intothe casing K, and out through discharge 0 into a suitable receptacle. B y meansof the set-screw g the shaft may be adjusted longitudinally to force the revolving parts nearer to or farther from the stationary ones to regulate .the degree of fineness to which the ore should be pulverized. The larger pieces of ore remain within the concavity of the crushing-plates until they gradually work down or out nearer to the outer ends of the ribs, where they are crushed more and more, and finally ground to a powder by the disks. I

The device is effective and easy of operation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In an ore crusher and pulverizer in which theore is operated upon by one plate revolving sloped to the center, substantially as' herein against another, the combination of the sta described. 1o tionary concave crushing-plate F and rcvolv- In witness whereof I hereunto set my hand.
