To all whom it may concern:

Be it known that I, JOHN BERGER SPENcE, a subject of the Queen of Great Britain, and a resident of London,England, have invented a new and useful Improvement in the Mannfacture of Metallic Compounds from Sulphur and Sulphides, (for which I have obtained a patent in Great Britain, bearing date July 3, 1879, in France, hearing date August 13,1879, in Belgium, bearing date March 13, 1880, and

in Italy,bearing dateMarch 13,1880,)ofwhich the following is a specification.

My invention consists in combining metallic sulphides with sulphur for the production of a material which is applicable. to various purposes in the arts.

In carrying out my invention I prefer to use the natural metallic sulphides, either singly or mixed, butpreferably those of iron and copper.

-quality of the metal it is desired to produce;

but I have foundthat for. general use the'addition of about thirty per cent. of sulphur will give good and useful results, a less proportion of sulphur producing a harder metal and a greater a softer metal.

The material thus obtained may be used for a great variety of purposes, both useful and ornamental. Thus, for example, when in a molten state it may be cast into various forms,

' such as statuary, vases, medallions, columns,

moldings, cornices, and otherornamental work for buildings, hip, ridge,or other tiles, and gutters for roofs, or slabs and blocks for building purposes generally, for making drain or other pipes, either alone or in combination with other i materials. The material may also be used, when in a molten state, for filling in the joints between the tiles and between the lengths of gut-J with a trowel.

ter, instead of mortar, cement, or solder, or instead of lead for stopping the joints of pipes. The material may also, be employed for obtaining reproductions from complicated works of art by casting in elastic molds. It will also serve for taking impressions from engraved copper or steel plates, or for making stereotype-plates.

It may also be used in the place of cement for plastering purposes generally. For this purpose I add only a small percentage of sulphur,

which will give, when in a heated state, a plas- 6o tic material capable of being readily worked It may also be used in the molten state as an enamel or paint for coatingblocks and wall-surfaces, for the lining of cisterns, drain and other pipes,for the protection of metals from oxidation and of wood from decay, andfor kindred purposes, forinsulating telegraph-wires, or for sealing bottles containing wine or other liquors.

The material may be applied with a brush to the various surfaces, or, in the case of pipes,

may be run through them in the liquid state. For insulating purposes the wires are drawn slowly through a bath of the heated liquid,

and for sealing bottles the corks and necks are 7 5 simply dipped therein.

I also propose to employ this metallic sulphide compound in place of sulphur when manufacturing vulcanized indiarubber and equivalent compounds. for coating paper and textile fabrics for rendering the same impervious to moisture. It may also be used in admixture with tar or pitch for asphalt. In some cases I may mix with the compound fibrous material toincrease 8 5 the strength.

The color ofthe material, which is naturally a dark gray, or nearly black, I modify by introducing into the mixture any suitable coloring matter.
