Be it known that-1, lilnxns'r Rooms, a

citizen (if-the United States, and resident of 'New Lexington, in the county o't' lerrv and w v i btate of Ohio, have Invented a new and use- :ful- Improvement in Liquid Coating Conn positions; and I do hereby declare the following to be a full, clear, and exact description thereof.

My. invent on relates to a liquid coating composition in the natureof a vehicle 'or' thinner for paint pigments or pulp. for

wood, brick or other, surfaces to which it may be' found' applicable. 1

Mostcompositions of this cln'iracter are,

ggenerally speaking, said to consist of pig- 'ment and a vehicle filling the space between the pigment particles. It is well-known that linseed oil andequiva'lent vegetable oils are the essential vehicles of such compos'i following as a tions'or paints. For many years the conr paratively high price of linseed oil or equiv- I 'materials.

cially feasible length of time. Because ol? the comparative cheapncss ofpetroleum and "some of its 'di stillates, attempts have been 'Jnade'to dilute the linseed oil with these When low boiling portions of petroleum Were-used, they acted merely as temporary diluents or thinners. They evaporated almost completely when the paint was applied and the result was merely'a paint film with .insuflic'ient vehicle. 'W hen higher'boili'ng or comparatively non-volatile petroleum fractions were used,,the paintsimply did not, dry in a" commercially feasi- Ihis result was naturally attributed on scientific grounds to the -s0-callcd non-drying attributed to its power of thickening or solidifying upon absorbing oxygen from the Petroleum 'not having this .power to any marked extent, would natu- 5o rally. not.dry adequately if usedf'as' the vehicleof a paint, and could only be usedto dilute or adulteratethe linseed oil vehicle. My invention conslsts .In the discover that crude petroleum of a parafiin base when mixed with a suitable drying mixture may be used to replacelinseed oil, in whole or in part, for mixing with pulp or other.
