FURNACE BOSE-JACKET AND BUSH-PLATE.
Specification of Letters Patent.-
Patented Aug. 25, 1908..
Application filed April 24, 1908. Serial No. 429,060.
To all whom it may concern:
Be it known that I, FRANK C. ROBERTS, a
- citizen of the United States, residing at instances it is pre Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Furnace Bosh-Jackets and Bosh-Plates, of,
which the following is a specification.
My invention relates to bosh plates placed inthe Walls of blast furnaces for the purpose of preservin and cooling said walls.
' In the building of modern blast furnaces it has been found necessary to provide a bosh construction of great strength and also'to securely support the bosh plates in such manner as to ermit their removal andrenewal without ifliculty. 'In some instances it is referred to inclose the bosh Walls in a meta casing, usually termed a bosh jacket, and to omit bosh fplates, .Whereas in other erred to strengthen the bosh walls by a series of horizontal bands with bosh plates located between them.
The object of my invention is to provide a bosh construction in which bosh plates may be used to advantage in connection witha bosh jacket, said bosh plates being so designed that they are ca able of being held securely in osition an of being removed and renewed without difficulty. I attain my object by means of the con-v struction illustrated in the accompanying drawings in which Figure 1 is a vertical section through one side of the bosh and lower part of a blast furnace; Fig. 2 is an elevation of a ortion of the bosh jacket shown in Fig. 1; igs. 3 and 4 are elevations showing other designs of bosh jackets; Fi 5 is asectional elevation on the lineVV' 0 Fig. 3; Fig. 6 is a sectional elevation on the line X Y of Fig. 4. Fig. 7 is an elevation showinga bosh platein place and Fig. 8 is a horizontal section on the 'iine Z Z of Fig. 7. 4
Similar letters refer to similar parts throughout the several views.
Referring to Fig. 1 :A represents the I Wall of the bosh of a blast furnace inclosed by a metal bosh jacket B eiitending from and supported by the mantel. plate G to a point above the twyers J. D and E are metal bands or ledges of angle section extending around the jacket B, the former being located on the inside and the latter on the outside of B. G is a bosh plate furnished on the are installed in H (see Figs. 7 and 8).
jecting upwards and bearing againstnthe jacket B. As indicated in Fig. 2, the bosh jacket B is provided with a series of openings 1 H separated by sections I of the jacket B, the openings H being cut in B of the proper size to accommodate the bosh plates C wl'lllflh e bosh'plate C may be furnished with flanges on each side, as well as on top, said side flanges bein of sufiicient width to cover the opening in all as indicated in Figs. 7 and 8. v i j Figs. 3 and 5 show another design of bosh jacket formed by a series of bands B, each band being of the necessary width to extend between the rows of bosh plates. The various bands are su ported theone from the other by straps I attached to said bands; the whole being supported as in Fig. 1 from the mantel plate G. Each band is provided at its lower edge with an angle section band or ledgeD on the inside. Figs. 1 and 2 is replaced by anglesections or ledges F extending between the straps I. The openings Hfor the insertion of the bosh plates are formed by dividing the space between the bands B by the straps I Figs. 4 and 6 show a modification of the design shown in Figs. 3 and 5 wherein the angle band or' ledge E is continuous and not in sections as in Figs. 3 and 5. In this case the straps supporting the bands B the one from the other, are attached to the flange of E which extends outwards.
In all designs the angle section bands D are intended to support the brickwork of the wall above the bosh plates C and the angle In this design E of section bands F (or F) are provided in order to attach the bosh plate thereto; in addition D and E add to the strength of the jacket.
It is evident that D and E need not be continuous aronndthe jacket in order to support the brickwork and the bosh plates; they may I mg and bearingagainst said jacket and having a flange at the-bottom of its outer end resting on and secured to said ledge.
2. In a blast furnace a metal bosh jacket provided with an opening, a bosh plate lo-' cated in said opening in the bosh jacket, said bosh plate having a flange at the top of its outer end projecting over the-upper edge of said opening and bearing against said bosh jacket and having flanges at the sides of its outer end projecting over the side edges of said 0 ening and having a flange at the bottom 0 its outer end resting on and secured a to a ledge attached to said bosh jacket below said opening, said led e projecting outwardly from said bosh jac et.
3. In a blast furnace, a metal bosh-jacket encircling the brickwork of the bosh wall and supported independently of said brickwork, a series of horizontal openings in said bosh jacket, metal ledges or bands attached to said bosh jacket above said openings and projecting inwardly, metal ledges or bands attached to said bosh jacket below said openings and projecting outwardly, bosh plates e tops of their outer ends jacket, metal ledges" or bandsattached to said bosh jacket above said openings and projecting inwardly, metal ledges or bands attached to said bosh jacket below said openings and projecting outwardly, bosh plates located in said openings, said bosh-plates having flanges at the tops of their outer ends projecting over the upper edge of said open ings and bearing against said bosh jacket and having flanges at the sides of their outer ends projecting over the side edges of said openings and having flanges at the bottoms of their outer ends resting on and secured to said ledges or bands projecting outwardly from said bosh j acket.= I
