UNITED STATES PATENT oPPIo JOSEPH HAY AMIEs, P PHILAD LPHIA, PENNSYLVANIA, ASSIGNOR are THE MIns ASPHALT COMPANY, 0F PHILADELPHI PENNSYLVANIA, A CORPORATION OF SOUTH DAKOTA. I l

SHEET-WOOD PAVING.

No Drawing.

To all whom it may-concern:

. Be it known that I, JOSEPH HAY AMIEs, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain newand useful Improvement in,

that it is noiseless, dustless, sanitary and of When made of hard wood nice appearance. block however it is very expensive, and otherwise unsatisfactory. The close grain of the wood block, used for paving, prevents the creosote, with which it is-treated, from penetrating sufficiently into the block to delay internal rot. Not only so, but the creosote will not prevent water from penetrating the block because the creosote must be of a specific gravity that will admit .of

its association with rain or snow water and in this way the water soaks mto the wood, and by. alternate dampening and drylngs, at

frequent intervals, decay is hastened. The

sheet wood paving of the invention possesses all the advantages and obviates all the objections of .wood block pavements.

' -The invention is practiced as follows :I use comminuted fibers, preferably such as old newspapers, and the like, and to the said material I may add paper composed largely of what the manufacturer calls hard stock; or I may add other long linefibers; or I may use with the above, peat or hay or straw or other-like materials; or I may use these separately. When using waste paper I first reduce it to a-pulp-and mix therewith a suflicient amount of'cle'an;

sharp very fine sand, in order to separate the fibers, and to prevent the pulp from forming into hard, tangled lumps. When the pulp, thus mixed withthe sand, is almost dry, the mass is agitated an dQ -the sand and fibers thus separated. When this is done the fibers will be practically straight, independent and untangled. In :this condition the fibers are mixed with a due amount of calcium oxid;

r or I may use calcium hydrate; the fibers are then treated with crude naphtha or other light oil or combinations thereof; The 0211- cium oxid will take up all the remaining water in the pulp and in slacking will produce considerable heat. Advantage of this fact is taken to add any desirable asphaltic or other bituminous, resinous or carbonaceous elements, either separately or combinedly, andwhentheseare well mixed I then add sufiicient dampened sand or the like, which has been previously mixed with. a desired amount of crushed calcium xid to coat over the mass. This treatment will procure a granular and friable condition of composition. It may now be laid in sheet form at convenience upon a foundation such as is used to receive wood blocks; This sheet wood paving is calculated to supersede wood blocks on account of its superiority since it possesses all the'advantages of the said wood block paving and also many others not possessed by it, among which may be considered its greatly extended durability and low cost,

tuminous, resinous, carbonaceous, and like pened sand and thelike, and calclum oxid to secure [a friableand granular condition of the resulting composition, and at convenience laying'the same upon a suitable foundation,'in the manner and for the purposes fully described. I

In testimony whereof I have hereunto signed my name' JOSEPH HAY AMI-ES.
