This invention has for its object improvements in the manufacture of refractory bricks, crucibles, and other articles, and also refractory linings for furnaces and converters, and in the preparation of lime to be moulded into forms adapted to metallurgical and other uses.
I prepare lime for these purposes in such manner that without converting it into hydrate of lime, the lime is made plastic or coherent, or in such a condition that it may be used for the manufacture of bricks, crucibles, tuyeres, or any other form or shape used in furnaces or otherwise as a refractory lining. I also use lime in a plastic, soft, or moistened state for lining furnaces by means of ramming round a mould or core, as usually carried out in lining Bessemer converters, ladles, and steel- furnaces with ganister sand or any other refractory material.
Hitherto there has been great difficulty in using lime for moulding bricks and the like, and for lining furnaces, on account of lime becoming hydrate of lime when moistened with water, in the usual way. I have discovered that when lime is mixed with crude petroleum-oil, petroleum-oil, or other like oils, or crude and waste products from the distillation of petroleum-oils, or tar free from, or practically free from water, lime may be moulded with or without pressure, but preferably with pressure. In this state it may be mixed with silica, oxide of iron, alumina, magnesia, or other materials, to make it more coherent after burning, as practiced in the manufacture of other refractory bricks.

 Riley’s English patent was involved in an unusual court case where the Court had to decide whether two patents, filed by different inventors on the same day and concerning substantially the same invention, could both be granted and co-exist; the Court decided in the affirmative and allowed both patents (Law Reports, Chancery Division, 1880, « in re Dering’s patent ».
