CHRIST PEIFER, OF ALLEGHENY, PENNSYLVANIA.
METALLUR GICAL FURNACE.
SPECIFICATION forming part of Letters Patent No. 411,226, dated September 17, 1889.
Application filed March 11, 1889. Serial No. 302,756. (No model.)
To aZZ whom, it may concern.-
Be it known that I, CHRIST PEIFER, of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Metallurgical Furnace, of which the following is a full, clear, and exact description.
This invention relates to that class of metallurgical furnaces known as straight draft furnaces for heating piles, the.
The object of the invention is to protect the walls of the heating-chamber at the part known as the neck from being cut away by the boiling slag which accumulates at this part. Ordinarily the side walls at the bottom of the neck are cut out by the slag in two weeks time and frequently in less time, but by my improvement the side walls at the point named will last just as long as the rest of the furnace, which is about ten months.
My invention consists in the construction hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.
Figure 1 is a side view of my improved metallurgical furnace, the floor-line being indicated by dotted lines. Fig. 2 is a cross-sectional view taken on line 00 0c of Fig. 1, and Fig. 3 is a sectional plan view on the broken line y y of Fig. 2.
In the drawings, 10 represents a metallurgical furnace, of which the neck of the heating-chamber is shown at 11. In the side walls 12 about this heating -cha1nber there are formed fines 13, which communicate with the surrounding atmosphere through the medium of ports 2. The flues 13 lead to the stack 14, the upper ends of' the fines being preferably slightly contracted. These ports 2 range along the lower sides of the neck 11 just below its fioorline, so that the draft of the furnace will cause a series of jets or streams of cold air to impinge against the side walls of the neck at the points where they are ordinarily cut away by the slag, and effectually prevent such action.
I do not claim jacketing the heating-chainber of a furnace of any description, nor the placing of air-chambers havin 5 end inlets along the side of a glass-furnace, for such constructions 1 consider foreign to my invention.
Having th us described my invention, I claim as new and desire to secure by LettersPatent A straight-draft metallurgical furnace 10, having a heating-chamber terminating in a neck 11 and a stack over the neck, the airspaces 13 in the side walls of the neck extending above and below its floor-line, provided below the floor-line with the series of cold-airinletports 2, opening through the outer side walls, and fines connecting the upper ends of the air-spaces with the interior of the furnace, whereby the draft will cause jets of cold air to be drawn through the ports :2 and impinged against the sides of the neck just below its floor-line, substantially as set forth.
