Description

PATENTED JUNE 30, 1908.
rus mmm: PETERS rol. mism/cram n4 c.
CHARLES C. JOHNSON, OF REDDING, CALIFORNIA.
FURNACE-TAPPING- SPOUT.
Specification of Letters Patent.
Patented June 80, 1908.
Application filed September 4, 1907. Serial No. 391,337.
.To all whom it may concern:
Be it known that I, CHARLES C. JOHNSON, citizen of the United States, residing at Redding, in the county of Shasta and State of California, have invented new and useful Improvements in Furnace-Tapping Spouts, of which the following is a specification.
My invention relates to spouts for drawing off the molten products of blast and other furnaces.
It consists in the combination with the spout, of a means for circulating cooling water through its walls, and in details of construction which willbe more fully explained by reference to the accompanying drawings, in which- Figure l is a vertical longitudinal section. Eig. 2 is a plan. Fig. 3 is a transverse section.
The draw-oill or discharge spouts of smelting and like furnaces are subjected to such intense heat that the molten metal flowing through them will in time adhere to, and clog the spout. In some cases water pipes have been introduced, but such arrangements are not wholly successful.
In my invention the spout is formed with integral jacket spaces and bracing partitions with water assages alternately at top and bottom, so that the circulating water takes a sinuous course in passing through the walls of the spout, and all parts are kept cool and prevented from being so softened by the heat as to sag and bend, and become too distorted for use.
A represents a s out with lugs 2 by which it may be removab y attached to the furnace. The spout may be of any suitable or desired depth, and is shown with the depth increasing from one end to the other. Transversely, the sides of the spout converge from the open top, to the bottom, which is segmental, and into which thesides merge, as shown. This spout is formed with double walls, as plainly shown in transverse section, and transverse partitions or diaphragms 3 are cast or formed integral with the spout, uniting the inner and outer sides at sufficiently close intervals, to support the sides and prevent distortion. Passages 4 are made near the top in alternate partitions and ufpon each side of the open central portion o the spout, and corresponding passages 5 are mac e near the bottoms of the intermediate partitions.
6 6 are inlet openings u on each side near the head, and 7 are outlets, of which there may be one or more near the bottom and lower end of the spout.
8 are hand hole plates, covering openings which serve primarily for the removal of the cores and core-rods, and may also serve for subsequent access to the interior.
When in use water is circulated through the s )aces and partition channels, and will thus leep the spout sufficiently cool to prevent adhesion of the 'fluid metal flowing therethrough and to prevent such softening of the spout by heat, that it will become distorted.
Having thus described my invention, what I claim and desire to secure by Letters Patent is* 1. The combination inthe discharge spout of a furnace, of exterior and interior walls and transverse bracing partitions therebetween, the said partitions being arranged substantially perpendicular to the 'llow of material through the spout whereby said spout is cooled to prevent adhesion of the `fluid metal flowing therethrough, and prevent it from sagging and bending, each alternate partition having openings near the top and the intermediate partitions having openings near the bottom, and the water inlet and discharge openings at opposite ends of the spout.
2. A discharge spout for furnaces, said spout having divergent double sides and curved bottoms connectingwith the sides, transverse partitions at intervals in the spaces between the sides, each alternate partition having openings near the top, and the intermediate partitions having openings near the bottom, water inlet openings upon opposite sides near one end, and discharge openings near the bottom and opposite end.
3. In a discharge spout for smelting and like furnaces, a double wall structure having a segmental bottom and divergent sides, transversely disposed bracing partitions between the walls, inlet and outlet water passages at the top and bottom, respectively, of opposite ends, openings through the top and bottom of the partitions upon opposite sides of the central portion of the spout, and hand hole plates in the bottom of the outer casing.
In testimony whereof I have hereunto set my hand in presence of two subscribing wit- IleSSeS.
CHARLES C. JOHNSON. I/Vitnesses:
GEORGE W. STAFFORD, A. R. HARVEY.
