Abstract: 317,003. Armstrong Cork Co., (Assignees of McCarthy, J. C.). Aug. 8, 1928, [Convention date]. Mosaic and inlaid linoleum.-In inlaid linoleum, some of the tesserae are formed by applying loose granular material to a backing, while the rest of the tesserae are formed from sheeted linoleum material, which may be of striated, marbled or jaspe pattern. The whole is then compacted, and certain parts may be depressed below the general level. As shown, the invention is applied to the making of a tile pattern linoleum, in which the parts 4, 5, Fig. 1, are formed by moulding, and the parts 7, 8 are cut from marbled and jaspe sheet linoleum respectively and inlaid. In making this material, sheets of marbled and jaspe linoleum are formed from the composition usually employed in making moulded inlaid linoleum, partly compacted, and cut to shape as required for the tesserae. The moulded inlaid parts of the linoleum are formed in the usual manner by sifting granular material through stencils on to a backing, and the cut tesserae are introduced in the desired places, as shown in Fig. 3. The partly compacted sheet 7 lies in the space between the granular material 6 which represents the mortar joint between the tiles. The material is then compressed, and the material 6 may be further depressed as described in Specification 261,950. The inlays of cut material may be of solid colour material.
