MURRAY GIBSON, OF PHILADELPHIA, PENNSYLVANIA;

COMPOSITION FOR THE ORNAMENTATION 0F WALLS AND CEILINGS.

SPECIFICATION forming part, of Letters Patent No. 290,227, dated December 15, 1883.

Application filed May 18, 1883. (No specimens.)

To all whom it may concern.-

Be it known that I, MURRAY GIBSON, a citizen of the United States, residing in the city and county of Philadelphia, and State of Penn sylvania, have invented a new and useful Oomposition for the Ornamentation of Walls and Ceilings, of which the following is a specification.

The object of my invention is the production of an improved plastic compound which shall be adapted to be applied to a wall, ceiling, or other surface to be decorated, whether such surface be composed of brick, concrete, wood, or other material,. either in its natural state, coated with plaster, or faced with canvas or other textile or fibrous fabric, and which, when applied, shall be adherent thereto, and be also adapted to set into a rigid mass.

This compound is especially designed to be employed in the practice of a method of ornamenting walls and ceilings invented by me,

application for patent for which was executed by me under the same date as thedate of execution of this application.

This compound is especially designed for use in the ornamenting of either the interiors or exteriors of dwellings or other buildings, although it is especially designed to be applied to surfacescomposed of or coated with wood, or to canvas, or other textile surfaces.

The compound is composed of red lead, (commercially known as sugar of lead, and being a preparation of white lead,) whiting, sawdust, linseed-oil, a mastic varnish, and beeswax. The whiting is added to the red lead in order to reduce both the weight and the cost of the resultant compound, and also to add to its bulk. To the mixed red lead and whiting is added sawdust. Fat, linseed-oil,

mastic varnish, and heated or liquid wax are then added to the sawdust, red lead, and whiting, and all the ingredients are thoroughly comniingled until the mass assumes a pasty consistency.

I do not restrict myself to any specific proportions, but prefer to take three parts in bulk of red lead, four parts of whiting, and three parts of sawdust, adding sufficient oil, varnish, and wax to render the mass of a pasty and coh erentconsistency. The sawdust serves to thicken and render rough the surface of the mass, and whenthe mixture becomes too thin is to be added in sufficient quantities to effect the required thickening, which is a matter dependent upon the skill of the workman, while the liquid elements are to be added to thin the compound in a manner likewise dependent upon the judgment of the workman.

The compound is applicable for the ornamentation of plastered surfaces, but for such surfaces is not as desirable as another compound which I have invented, and for which I have executed an application for Letters Patent bearing the same date as this application.

The mass in its, pasty condition is in readiness to be applied to the surface which is to be ornamented with it according to my method already referred to.

Having I thus described my invention, I claim A compound for the ornamentation of walls, ceilings, and other surfaces, composed of red lead, whiting, sawdust, linseed-oil, copal varnish, and beeswax, substantially as described.

In testimony whereof I have hereunto signed my name this 4th day of April, A. D. 1883.

MURRAY GIBSON.
