Be it known that 1, CHARLES ARNOUDTS, a' citizen of the United States, residing at Seat-tle, King county, State of Washington, have 5 invented a new improved and useful composition of matter to be used for covering pilesv to protect them against the ravages of the teredo in the salt waters of bays, harbors, seas, and oceans, of which the following is 9.

been patented to myself or others with my consent or knowledge in this or a foreign country. 7 My invention consists in the composition of proportions and applied in the manner here-i tion for temperate zones, -for warmer zones; the amount of tar used to be reduced, and the amount of pitch and asphaltnmincreased in proportion so that the composition willj and in colder zones the amount of coal tar to' e be increased in the same proportion ground lass ulverized to the fineness of coarse n equa parts. I 1 nd or pulverized to. the fineness of flint sand can be used as a cover the pile. The ground glass and flint. osand (or ground rock) to be thoroughly mixed and heated to at least 150 of heat, are then applied to the pile until the coating of tar,

pitch and asphaltnm already applied, is thoroughly and completely impregnated and coated therewith and no more will adhere. v Narrow strips of battin r gged with the o same composition and in the same manner as the pile are then nailed .to the pile lengthwise with .00 er, zinc, or galvanized iron nails, at asucient' distance apart to protect 5 1 V the pile covering in transportation or driving.

I do not claim broadly the use of asphaltum in any composition for the purpose above explained, as the use of it has been suggested with sand or earth; ,nor do I claim the use of 5 I calcareous material broadly as a coverin for piles or timbers, as pulverized shells ave heretofore been described for this purpose in connection with pitch and tar. J By the use of the above compositions ap-' 6o plied as above described they make a cheap, 1 durable andeflicient covering for piles completely protecting them'aga'inst the ravages of the teredo in the salt waters of 'the bays, harbors, seas and oceans. By applying the ground glass while heated it becomesembedded in the coating of tar, pitch and asphaltum already applied and .forms a coating that the y I teredo cannotbore. I f

What I claim, and desire to secure by Let- 7o ters .Patentof the United States, is-

r The herein described com osition of mat- ;ter to be used for covering p1 es consisting of t a r, pitch and asphaltuml and ground ;;glass and flint sand or -rock' in the proportions specified, combined and applied in the manjner above specified. l
