G-Eo, .ELv NiDERBURGH, OF NEW YORKJN; Y.
Specification forming part of Letters Patent No. 48,745; dated July 11,
To all whom it may concern;
Be it known that I, GEORGE DEiznuaen, of New York .city, in the county and. State ofNewYork,have invented a new and use-. ifnl Building-Block as a Substitute for. Bricks and Stones; and I'do hereby declare that the following is a full, clear, and exact description thereof. v
unslaked, intimately combined with a large proportion of clean sand or other siliciousmatter with the slightest possibleamount of moisture, and molded under heavy pressure, have been found 'to be a cheap and excellent substitute for brick and stone in all building purposes. These blocks, however, whemfir'st formed, are comparatively tender and friable and liable to injury by any rough handling; hence in their manufacture great care is required in moving them until they have become hardened by exposure to the air, and, again, they are'not in a condition to bear weight or resist the action of the elements'until they have been exposed to the air for several months. 4 I The object of my present invention is to avoid these objections and to obtain a block which shall not only be hard and firm when it comes from the press, but also inore durable in its character than the so-ca'lled Foster block, and be ready stones for building purposes.
Blocks formed of powdered lime, slaked or My new building-block is formed as follows:
Good'powdered lime, either slaked'or unslaked,
is first mixed thoroughly and'intimatelywith clean damp sand (or other equivalent silicious substance free from earthy matter) in the pro portiou. of about one part-of lime to ten or twelve parts of sand. This mixture of lime and sand,when ready-for molding, i s-next moistened with a liqu id silicate'of such strength as will promptly form atieor bond between the particles ofithe mass, and being placed in suitable molds is at once submitted to powerful press- 'ure before the composition has become set by the action of the silicate.
A block thus silicated in its formation will be, when completed, so tough and strong as to be at once ready for handling, and from the superior cohesion of its particles can'be made" larger than by any otherproces's; and,
- Having thus fully described my'ini'ention, I
claim- As a new article of manufacture, a silicated building-block formed substantially in the manner herein set forth.
