CHARLES DIEBOLD, OF LEBANON, PENNSYLVANIA, AS SIGNOR TO E. L, BUTTERFIELD, TRUSTEE, OFBROOKLYN, NEW YORK;
\ Letters Patent No. 101,835, dated April 12, ism.
IMPROVEMENT IN THE MANUFACTURE OI BUILDING-BLOCKS PROM SLAG.
The Schedule referred to in these Letters Patent and making part of the same.
1, CHARLES DIEBOLD', of Lebanon, Lebanon county, State of Pennsylvania, have invented a certain Improvement in the Process of Manufacturing Building- Blocks or other Articles from Slag, of which the following is a specification or description.
In the method now in use, the flasks or molds are taken at the proper time to the iron-furnace, and the melted slag is drawn directly into them and left to cool andharden therein, but this process requires a great number of molds, owing to the time required for the slag to cool, and moreover, the blocks thus produced are hard and brittle, especially when the air is permitted to reach the block during the process of cooling. I
I have found that by retarding the cooling-process and confining the blocks from the air, the defects mentioned are remedied. Toaccomplish this, I pursue the following course:
When the slag is drawn into the flasks or molds it is allowed to remain just long enough to solidify to such an extent that it can be moved without the molds, when I rake the molds from the blocks, and
then remove the blocks and pile them up in heaps and cover them with sand or other material to exclude the air, where they are allowed to remain till cold. In case it is not desired to remove the molds, they can be covered, and the air excluded while the blocks cool in them. By this process the blocks produced are rendered tough as well as hard, so that they can be dressed the same as any building-stone.
Ha-ving described my invention or process,
What I claim as new, and desire to secure by Let ters Patent, is
1. The removing the blocks from the molds and covering them with sand or other material, so as to exclude the air during thecooling-process.
2. The excluding theiair from the blocks during the cooling-process, by covering with sand or other material, whether the blocks are still left in the molds or first removed. I
