Claim 1

AN APPARATUS FOR SHAPING AND COMPRESSING SHEETS OF ABSESTOS CEMENT INTO ARTICLES OF COMPLEX CONFIGURATION, COMPRISING A. A HORIZONTAL, RIGID TUBULAR HOUSING INCLUDING END WALLS HAVING SUBSTANTIALLY CENTRALLY LOCATED OPENINGS THEREIN, B. A SLIDE HAVING A LENGTH AT LEAST TWICE AS LARGE AS THE LENGTH OF SAID HOUSING AND BEING SLIDABLE THROUGH SAID OPENINGS IN THE END WALLS OF THE HOUSING SO AS TO SELECTIVELY DISPOSE DIFFERENT PORTIONS OF SAID SLIDE WITHIN SAID TUBULAR HOUSING, C. A MOULD CARRIED BY EACH OF SAID PORTIONS OF THE SLIDE, EACH MOULD INCLUDING (1) A RIGID LOWER PART HAVING AN UPPER SURFACE CONFORMING TO THE UNDERSIDE OF AN ARTICLE TO BE SHAPED THEREBY, AND (2) A REMOVABLE, ELASTICALLY YIELDABLE SOLID UPPER PART EXTENDING OVER AT LEAST A SECTION OF SAID LOWER PART TO RECEIVE A SHEET OF ASBESTOS CEMENT THEREBETWEEN WHEN THE RELATED PORTION OF SAID SLIDE IS DISPOSED OUTSIDE OF SAID HOUSING (3)SAID ELASTICALLY YIELDABLE UPPER PART OF THE MOULD HAVING A LOWER SURFACE CONFROMING TO THE CONFIGURATION OF THE CORRESPONDING PART OF AN ARTICLE TO BE SHAPED BY THE MOULD D. AN INFLATABLE BODY FIXED WITHIN SAID HOUSING ABOVE SAID SLIDE, AND E. MEANS FOR SUPPLYING FLUID UNDER PRESSURE TO SAID BODY MEANS SO AS TO INFLATE THE LATTER AND THEREBY CAUSE THE BODY TO PRESS SAID ELASTICALLY YIELDABLE UPPER PART OF THE MOULD WITHIN SAID HOUSING AGAINST THE RELATED RIGID LOWER PART FOR COMPRESSING AND SHAPING THE SHEET OF ASBESTOS CEMENT THEREBETWEEN INTO THE FORM OF A DESIRED ARTICLE.
