TO' WHOM IT MAY CONCERN:
Be it known that I, BENJAMIN N. LAMPMAN, of Rutlaiid, in the county of Rutland, and State of Vermont, have invented certain new and useful Improvements in Concrete Pavements; and I hereby declare the followingto he a full, clear, and exact description of the same.
The object of my invention is to make a cheap and durable concrete walk or pavement which will dry or harden so a-s to be fit for use in a. much shorter space of time than is the case when ordinary concrete is employed. To do this I. proceed as follows 0 i I first take gravel, in size fronia goose egg down, and cover it with coal tar, stirring and mixing the two together thoroughly until the cobble-stones have all become completely coated with the tar This is intended to form the foundation of the pavement, and is spread over the bed prepared for it so as to form a layer about two or three inches in thickness, which ispounded down with tamping irons, or rolled with a. roller of suitable weight, until the stones are pressed firmly together so as to form a compact and solid mass. This foundation is covered with alayer of concrete, made in the proportion of three parts of iron-furnace cinders to one part of eoarsesand. Instead, however, of iron-furnace cinder-s, ordinary coal ashes and ashes from blacksmiths fires may he used. The cinder-s or ashes are ground fine, so as to sift through a one-fourth inch n esh, and they, together with the sand, are then well mixed with coal tar, so as to form a concrete, which is spread over the cobble-stone foundation in a layer of about one and onefourth inch in thickness. After. this has been done, air-slaked lime should be siftcdonso as to completely cover the concrete. The addition of the lime is of considerable importance, and should be carefully attended to, as the effect of it is not onlyto destroy the smell of the coal tar, but tmharden the walk or pavement much more readily than can he done by any other method now in use. Indeed, a walk made in. this manner will harden sufficiently in a day to allow of its being used for all ordinary purposes. This layer of lime is well sanded, and the pavement is rolled thoroughly with a clean roller.
The edges'are then tamped up, and-the whole wall; is covered with a layer of sand, which is left on until the wall: has perfectly hardened. v
A pavement made by this process possesses great durability, and can bemude with little cost. As before; said, it dries rapidly, being ready for use in about a. day after it is completed, and is tougher and much less brittle than other walks ofthis kind usually'are. t is, therefore, especially adapted for general use, not only" for walks and roads, but as a floor in stables, engine-houses, barn-yards, &c., &c.
Having described my invention, and the manner in which the same is or may he carried into effect, what I claim, and desire to secure by Letters Patent, is-
The concretepavcment herein described and set forth. I In testimony whereof I have sign ed my name to this specification before two subscribing witnesses.
