IMPROVEMENT IN BESSEMER-CONVERTER BOTTOMS.
Specication formilg part of Letters Patent No. 188,898, dated March 27, 1877; application iiled December 29, 1876.
To all whom 'it may concern Be it known that I, ANDREW'JACKSON HAWS, of Johnstown, in the county of `Gambria and State of Pennsylvania, have invented` a certain new and useful Improvement in Bessemer-Steel-Gonverter Bottoms, of which the following is a specication: My invention relates to a mode of attaching bricks which form the bottom' of a Besse mer-steel-converten the said bricks being constructed with lugs projecting down into the tuyere-box, and being constructed with longitudinal tuyere or blast openings extending through the said lugs.
My invention consists lin securing the'brick Nfwithin the top platevotthe tuyere-box. by i means of a ring of metal or ,other material titting loosely around the inwardly-projeecting lug of the brick,annular grooves being pro- -vided on the exterior of the lug and the in- .terior of the ring to receive a body of cement,
" which thus locks the Vtwo together.
In the accompanying drawing, Figure l is Ta. vertical section of a tuyere-brick-with a `fastening applied.
-Fig. 2 isan under-side view .of the same. Fig. 3 is a vertial section are formed with lugs A' projecting down Y through the top plate B of the tuyere-box H,
and with longitudinal tuyere-openings a extending completely through the said bricks So as to communicate with the interior of the box. C C are fastening-rings applied around the lugs within the tuyere-box, and formed with annular grooves c, which are preferably located on a lever with corresponding annular grooves on the outer surface of the brick lugs. The space between the lug A and ring C, and alsothe annular grooves within the ring with which said space communicates, receives a body of cement, D, so as to firmly lock the ring and lug together, and thereby secure the brick to the tuyere-box.
It willv be observed that this mode of ap plying the rings C and filling the space Within them with cement, forms at once a perfect lock to x the bricks in position, and at the same time tightly closes the joint between the brick lugs andthe top plate of the tuyerebox.
Having thus described my invention, the
following is what I claim as new and desire to secure by Letters Patentlhe bricks A, provided with lugs A', projecting within the tuyere-box, in combination with locking-rings D, fastened theretoby a body of cement or other material, substan- -tially as set forth.
