JOHN JAMES DAWSON, OF GLOBE, ARIZONA.

APPARATUS FOR PRGDUCING COPPER.

Specification of Letters Patent.

Application filed. February 14, 1920. Serial No. 358,729.

To all whom it may concern:

Be it known that I, JOHN J. Dawson, a citizen of the United States, residing at Globe, in the county of Gila and State of Arizona, have invented certain new and useful Improvements in Apparatus for Producing Copper, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an apparatus for producing copper, and the object of the invention is the construction of a simple and efiicient apparatus for the manufacture of copper.

lVith this and other objects in view, my invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter specifically described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a View in side elevation of an apparatus constructed in accordance with the present invention.

Figure 2 is a vertical sectional view of the converter, while Figure 3 is a vertical sectional view of the converter taken at right angles to the line on which Figure 2 is taken.

Figure 4 is a View taken on line 4l4, Figure 1, looking in the direction of the arrow.

Referring to the drawings by numerals, I

reduce copper ores to a matte in a furnace,

and then the matte is transferred to the converter 1, into which it is blown by compressed air until reduced to copper. The air is conveyed from the air compresser 2, through the primary air pipe 3, to one of the trunnions 4: of the converter, thence through the trunnion passage 4 to a short pipe 5, which pipe 5 communicates with the wind box 6 at the top thereof. Secured to the bottom of the wind box 6 is a number of small pipes or twyers 7; the air is allowed to pass from the wind box 6 through these numerous twyers 7, into the interior of the converter 1; the air upon coming in contact with the hot matte causes the matte to congeal on the inner ends of the small pipes or twyers, thereby preventing the air from entering the converter, usually making it necessary to employ men with hammers and steel rods to punch the twyers continually to keep the converter blowing or working.

In my apparatus I feed gas or oil into the main air pipe 3 so as to pass into the converter with the air. hen the oil comes in contact with the hot matte, it prevents the matte from congcaling or freezing upon the small pipes or twyers, thereby leaving a free passage for the air to pass into the converter. This is accomplished by connecting a high pressure air pipe 8, at its inner end, to valved casing 9, the valved casing 5) being connected to the valved casing 10 so that the passage of air from the air compressor 2 into the main air pipe 3, as well as the passage of air into the high pressure pipe 8, can be controlled to a nicetyl The air passing through pipe 8 enters the oil tank 11, which oil tank 11 has an outlet oil pipe 12 connected to its bottom, and the outer end of pipe 12 is connected to the valved casing 13, which casing is connected also to the primary air pipe 3 so that the oil is allowed to enter pipe 3 in quantities as desired by the operator, the gas or oil mixing with the air and entering the wind box 6, thence the small pipes or twyers 7, thence the converter 1.

The converter 1 is usually mounted upon the trunnions 4, and, therefore, the connection of the wind pipe 3 is preferably through the trunnion so that the action of the converter will not be impaired. The wind box is carried upon the side of the converter 1, being mounted upon the small pipes or twyers 7, and the short pipe 5 forms an efficient connection between the stationary wind box and the trunnion 4.

What I claim is:

1. In an apparatus of the class described, the combination of a converter provided with trunnions, one of said trunnions provided with an air passage, horizontal twyers upon the side of said converter and opening on a horizontal plane into the same, a horizontal wind box against the side of the converter and connected to the top of the horizontal twyers, a short pipe connected at one end to the air passage in the trunnion and connected at its outer end to the top of the horizontal wind box, a primary air pipe connected at one end to the air passage in the trunnion, an oil tank, a valved pipe connected at one end to the primary air pipe and at its opposite end to said oil tank, and said valved pipe connected at one end to the bottom of the oil tank and being connected at its other end to the primary air pipe near the trunnion.

Patented Jan. 1th, ELQZZ.

verter near its bottom, a short pipe communieating at one end with the air passage in the 10 trunnion and having its other end connected to the Wind box, and means for supplying air and an inflammable element to the air passage in the trunnion.

In testimony whereof I hereunto ailiX my 15 signature.

JOHN JAMES DAXVSON.
