MEANS FOR PROTECTING FURNACE-WALLS.
SPECIFICATION forming part of Letters Patent No.*601,'7 59, dated April 5, 1898.
Application filed December 28, 18,96. Serial No. 617,162, (No model.)
To a/ZZ whom it may concern:
Be it known that I, JAMES SCOTT, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Means for Protecting Furnace-Walls, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l shows in front elevation a part of the wall of a blast-furnace constructed in accordance with my invention. zontal section on the irregular line II II of Fig. l, and Fig. 3 is a vertical section on the line III III of Fig. 1.
The purpose of my invention is to provide means for strengthening and preserving the walls of blast-furnaces between the twyercoolers. It is of general application, but it is of peculiar use in blast-furnaces constructed according to the recent practice-with a greaty number of twyers-in which, by reason of the small space between the twyer-coolers, the brickwork for supporting the upper boshwalls of the furnace and for resisting the outward pressure on the furnace-Walls is reduced.
To this end my invention consists in a combined buckstay and cooler having a hollow body portion set vertically in thel brickwork between the twyer-coolers, so as to render support to the upper bosh-walls, and having external lateral flanges which fit against the furnace-wall on the outside and thus brace it against outward pressure. A current of water is maintained through the body of the buckstay, and it is thus cooled and the furnacewall is prevented from being cut out between the twyer-coolers.
In the drawings, 2 represents the furnacewall, and 3 3 are the twyer-coolers, in which the twyers 4 are set. 'In the furnace-wall between the adjacent twyer-coolers are set the water-cooled buckstays 5, made in the form of hollow oblong boxes having external vertical flanges 6, which fit against the furnace-wall. The buckstays are held securely in place by being fitted under the hearthplates 7 at their lower ends and under a band 8, which encircles the furnace, at their upper Fig. 2 is a horiends. vTo provide more effectually for the water-cooling of these buckstays, I construct leach with a vertical partition 9, dividing the is preferably connected with and derives its Water from the outlet-pipe 12 of the twyercooler, so that the water shall' ilow from the twyer-cooler to and through the buckstay.
Opposite to the end of the inlet-pipe l0 I prefer to form an upwardly-directed lip 13, which causes the entering water to impinge upon the end of the inlet-chamber of thebuckstay and prevents the excessive heating of the wall'and casting at that point which otherwise might be occasioned bythe collection of air-bubbles. At the lower end is an opening closed by a removable plug 14, adapted to facilitate the washing out of the buckstayy when occasion requires the same.
In the drawings I show two forms of conthe weight of the masonry. The other buckstay at the right is made of uniform width from top to bottom and likewise serves as a column to support the wall and as a cooler to preserve it from being burned out.
The advantages of my invention will be appreciated by those skilled in the art.
Within thevscope of the invention as defined in the claims modifications may be made .in the form and construction of the parts,
