ORE PULVERIZER AND CONCENTRATOR.

Specification of Letters Patent.

ratenteol April. 23, 1907.

Application led April 27, 190.` Serial No. 313,926.

.To @ZZ whom it may concern:

Be it known that I, OBADIAH K. Mc- CUTcr-IEON, a citizen of the United States, re-

.siding at Pittsburg, in the county of Alleimprovement in ore pulverizers and concentrators, and is more particularly adapted to the crushing and extracting of free-milling gold ores, although other ores of a harder formation may be quickly reduced to a pulverized state in my device.

In the accompanying drawings, forming a part of this specification, I have shown several views of my invention.

Figure 1 is a sectional view of the invention; Fig. 2, a top plan view, partly broken away. Fig. 3 is a cross-sectional view taken on line 3 3 of Fig. l. Fig. 4 shows two views of the securing-bolt, and Fig. 5 is a similar view of one of the beaters used to pulverize the ore.

Numerals of reference designate like parts throughout the different views, l being the framework forming the body portion of the pulverizer. Inside of this framework is arranged a steel trough or receptacle 2, in which the ore is pulverized and washed with water, thus separating the gold from the ore. rihe discharge end of the pulverizer is slightly raised above the opposite end, being about one-third of an inch to the foot, and the gold which is being separated from the ore during the pulverizing process will naturally settle to the lowest level, which in this device will be at the receiving end of the machine. A largev percentage of the gold will therefore settle or concentrate on the .bottom of the machine at the lowest point of the trough while the pulverized ore is being carried forward and out of the discharge end.

Extending longitudinally the entire length of the machine is a cylinder 3, which is made to revolve on gudgeons 4 4l, mounted in each end of said cylinder and secured thereto.

These gudgeons 4 4 are in turn operatively mounted in suitable bearings 5 5 adjacent each end of the pulverizer. Arranged through the cylinder 3 at stated intervals are a series of securing-bolts 6 6, on one end of eachbolt being an enlarged portion for receiving the bif'urcated end of the beaters 7 being secured thereto by a bolt or other suitable means. On the opposite end of each bolt 6 is a nut 8, by means of which the beaters 7 may be drawn tight against the cylinder 3 and held thus in this position. It will also be seen that the lower end of each beater is hollowed out and cut on a slight angle sufficient to conform to the contour of the cylinder.

The securing-bolts 6 6, passing through the cylinder 3, are so arranged that the beaters 7 willy be held at an angleand inclining toward the discharge end of the pulverizer for the purpose of gradually moving the contents of the receptacle 2 forward during the process of crushing. An ordinary packing-gland 9 is arranged over the gudgeons 4 at each end of the pulverizer.

At the top of one end of the machine is an ore-receiver 10, which connects with a sluice-box 10, and on the gudgeon 4 is mounted a power-wheel 11.

A spout 12 is arranged at the discharge end of the machine, out of which the pulverized ore is expelled.

On top of each bearing 5 is an oil-cup 14.

The ore is carried or fed into the pulverizer by water through a series of troughs-or sluiceboxes any desired distance, and while in transit this water is softening the ore and decomposing it readyh for the pulverizing process. One of the essential points 'of advantage in my invention is the fact that the same water that is being utilized to carry the ore to the pulverizer is likewise used to wash the ore, aid in the process of pulverization, and carry the ore out of the machine. The posi-- tion of the feed-pipe l0 directly over the cylinder 3 will make it possible for the rapidlyrevolving beaters 7 7 to crush the ore and commence the process of pulverizing the instant that said ore is admitted into the trough 2. These beaters 7 7 are constructed in size two and one-half inches by three inches by seven inches, making them sufliciently strong to reduce the hardest of ores, and when the cylinder 3 is made to revolve at a very rapid speedabout two hundred and IOO IIO

^ scribed, and by the time it is ready to be expelled out through the spout 12 it is reduced to a muddy consistency.

In case any of the beaters should become loose or damaged they can easily be reached in order to be tightened or replaced by simply raising the top of the machine.

A curved rim or block 15 about twol and one-half inches high is placed infront of the intake to the spout 12, which will act as a dam and hold back any of the gold vthat might otherwise pass through said spout.

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

1. In a pulverizer and concentrator, a suitable receptacle designed to receive water and ore, a cylinder j ournaled longitudinally of the receptacle, means for rotating the cylinder; the said cylinder having a series of diagonally-disposed openings therethrough, bolts in said openings having flattened heads extending longitudinally thereof and provided with apertures, means for securing the bolts in place, beaters applied to the'bolt-heads, said beaters consisting of blades having bifurcated inner ends to receive the heads of the bolts, and having transversely-disposed apertures adapted to register with the apertures of the bolts, and securing means engaging the bolts andgbeaters.,

rections at right angles to the recessed por* tion to lie longitudinally of the cylinder, the bevel of the ends being at right angles to the pitch of the apertures in the cylinder.

3. In a pulverizer and concentrator, a suitable receptacle, a cylinder journaled therein, means for rotating the cylinder, said cylinder having diagonally-disposed apertures, bolts having shoulders in stepped relation to engage the periphery of the cylinder, the said bolts having flattened heads extending beyond the periphery of the cylinder, beaters having bifurcated ends to receive the heads of the bolts, said inner ends being transversely recessed and beveled in directions at right angles to the recesses, means for securing the beaters to the bolts, and a suitable supply-hopper and dischargeespout for the receptacle.

In testimony whereof I affix my signature in presence of two witnesses.

OBADIAH K. MCCUTCHEON.
