IMPROVEMENT I'N CASKS FOR HOLDING OEL, QUICKSILVER, 80C.

Specification forming part of Letters Patent No. 34,05l, dated January 7, 1862.

T0 @ZZ whom it may concern:

Be it known that we, ANDREW D. CAMP- BELL and EL'BERT PEROE, of New York, in the county and State of New York, have invented a new and improved mode of preventing barrels or vessels constructed of fibrous or porous materials for holding quicksilver, pe troleum, or hydrocarbon fiuids from leaking; and we hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

The nature of our invention consists in impregnating wood or anyfibrous or porous materials suitable for the construction of barrels or vessels for holding quicksilver, petroleum, or hydrocarbon fluids with' any compound containing' silica, either before or after the construction of said barrels or vessels,by means of forcibly pressing a solution containing silica into the pores and crevices of said materials until the` pores and crevices are entirely impregnated and filled, to prevent the barrels or vessels from shrinking or expanding when exposed to the action of the elements, and in lining the interior of barrels or vessels with cloth, paper, or other suitable fabric glued firmly to the interior sides of the barrels or vessels, and covering the said lining with a coating of any compound containing silica to render the barrels or vessels impervious to the penetrating action of quicksilver, petroleum, or hydrocarbon tluids.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

Efe construct our barrel or vessel in any of the known forms. The barrel is then immersed in a hot bath of a solution of silicate of potassa and soda, an opening being made in the barrel or vessel to allow the solution to enter and fill it. The bath and its contents are then subjected to a heavy hydraulic or other pressure sufficient to force the solution into the pores and crevices of the materials of which the barrels or vessels is constructed, and into the joints of said vessels or barrels, until they are entirely filled and saturated with the liquid silica, which,when dry,will effectually prevent the shrinkage or expansion of the materials of which said barrel or vessel is constructed when exposed to the action of' the elements, and thus vprevent leaking of its contents. A lining of cloth, paper, or other suitable fabric is then glued to the interior sides, bottom, and top, b b b b, as shown in the accompanying drawing of said barrel or vessel,

with ordinary glue, and the lining is covered l materials suitable for the construction of barrels or vessels for holding quicksilver, petroleum, or hydrocarbon fluids, and to fill the joints of said barrels or vessels, in combination with a lining oi' cloth, paper, or other suitable fabric glued to the interior of barrels or vessels, and coated with any compound containing silica to render them impervious to the penetrating action of quicksilver, petroleum, or hydrocarbon iiuids, in the manner above set forth.

2. Specifically/,theimpregnation of wood or other materials suitable for the construction of barrels or vessels for holding Quicksilver, petroleum, or hydrocarbon fluids, either before or after such vessels or barrels are made,

Vwith any solution containing silica by means of heat and pressure, for .the purpose above set forth.

3. Specifically, the application of alining of cloth, paper, or other suitable fabric glued to the interior of barrels or vessels for holding quicksilver, petroleum, or hydrocarbon fiuids, and coated with Vany solution containing silica, for the purpose above set forth.
