CARL WIN KLER J OE BERN, SWITZERLAND. I V MANTBLE OF MOLDS FOB, CASTING STEREOTYPE PLATES. Application filed Februar 's, 1527. serial No. 166.223. i In casting stereotype plates the mantle matrix in the usual way. Behind this wall of the mold very frequently gapes somewhat a is provided the deep hollow chamber Z),

This distorst-ance'and is provided with openings Z) for I 5 tion cannot be properly prevented by simply the circulation of air or other substance cooling the mantle by water passing through therethrough, and the back 0 of the mantle a hollow chamber behind the wall on which is provided with a water chamber d. Water the matrix lies, because the mantle must enters this chamber atone point, for examhave a certain temperature, in order to ple, at e, and leaves at another point, such '10 obtain good'plates.
