Structure and manufacture of bowling balls

Claim 1

A PROCESS OF MANUFACTURING A BOWLING BALL, SAID PROCESS COMPRISING THE STEPS OF PRESSING POLYMERIZABLE MASSES OF PUTTY-LIKE CONSISTENCY BETWEEN THE CONCAVE SPHERICAL SURFACES OF A PAIR OF FIRST OUTER DIE MEANS AND THE CONVEX SPHERICAL SURFACES OF A FIRST INNER DIE MEANS TO PRODUCE A PAIR OF PORTIONS OF A FIRST SHELL, THE CONCAVE SPHERICAL SURFACE OF ONE OF SAID PAIR OF FIRST OUTER DIE MEANS BEING CLOSER TO ITS ADJACENT CONVEX SPHERICAL SURFACE OF SAID FIRST INNER DIE MEANS THAN IS THE CONCAVE SPHERICAL SURFACE OF THE OTHER OF SAID PAIR OF FIRST OUTER DIE MEANS TO ITS ADJACENT CONVEX SPHERICAL SURFACE OF SAID FIRST INNER DIE MEANS SO THAT A PAIR OF SEATS ARE FORMED IN SAID PAIR OF PORTIONS OF SAID FIRST SHELL, THE THICKNESS OF ONE OF SAID PORTIONS OF SAID FIRST SHELL BETWEEN ITS SEAT AND ITS OUTER PERIPHERY BEING GREATER THAN THE THICKNESS OF THE OTHER OF SAID PORTIONS OF SAID FIRST SHELL BETWEEN ITS SEAL AND ITS OUTER PERIPHERY, WITHDRAWING SAID PAIR OF FIRST OUTER DIE MEANS FROM SAID FIRST INNER DIE MEANS IN ORDER TO RELEASE SAID PORTIONS OF SAID FIRST SHELL FROM SAID CONVEX SPHERICAL SURFACES OF SAID FIRST INNER DIE MEANS AND WITH SAID PORTIONS OF SAID FIRST SHELL IN ADHERENCE WITH SAID CONCAVE SPHERICAL SURFACES OF SAID PAIR OF FIRST OUTER DIE MEANS, RELATIVELY WITHDRAWING SAID FIRST INNER DIE MEANS FROM SAID FIRST PAIR OF OUTER DIE MEANS, INTIMATELY SEATING A SPHERICAL INSERT IN SAID SEATS BETWEEN SAID PORTIONS OF SAID FIRST SHELL, PRESSING SAID PORTIONS OF SAID FIRST SHELL INTO CONTIGUITY ABOUT SAID INSERT IN ORDER TO ENCLOSE SAID INSERT WITHIN SAID SHELL BY OPERATION OF SAID FIRST PAIR OF OUTER DIE MEANS THEREBY PROVIDING A BOWLING BALL CORE, PRESSING POLYMERIZABLE MASSES OF PUTTY-LIKE CONSISTENCY BETWEEN THE CONCAVE SPHERICAL SURFACES OF A PAIR OF SECOND OUTER DIE MEANS AND THE CONVEX SPHERICAL SURFACES OF A SECOND INNER DIE MEANS TO PRODUCE A PAIR OF PORTIONS OF A SECOND SHELL, THE CONCAVE SPHERICAL SURFACE OF ONE OF SAID PAIR OF SECOND OUTER DIE MEANS BEING SUBSTANTIALLY THE SAME DISTANCE FROM ITS ADJACENT CONVEX SPHERICAL SURFACE OF SAID SECOND INNER DIE MEANS AS IS THE CONCAVE SPHERICAL SURFACE OF THE OTHER OF SAID PAIR OF SECOND OUTER DIE MEANS FROM ITS ADJACENT CONVEX SPHERICAL SURFACE OF SAID SECOND INNER DIE MEANS SO THAT A PAIR OF SEATS ARE FORMED IN SAID PAIR OF PORTIONS OF SAID SECOND SHELL, THE THICKNESS OF ONE OF SAID PORTIONS OF SAID SECOND SHELL BEING SUBSTANTIALLY THE SAME AS THE THICKNESS OF THE OTHER OF SAID PORTIONS OF SAID SECOND SHELL, WITHDRAWING SAID PAIR OF SECOND OUTER DIE MEANS FROM SAID SECOND INNER DIE MEANS IN ORDER TO RELEASE SAID PORTIONS OF SAID SECOND SHELL FROM SAID CONVEX SPHERICAL SURFACES OF SAID SECOND INNER DIE MEANS AND WITH SAID PORTIONS OF SAID SECOND SHELL IN ADHERENCE WITH SAID CONCAVE SPHERICAL SURFACES OF SAID PAIR OF SECOND OUTER DIE MEANS, RELATIVELY WITHDRAWING SAID SECOND INNER DIE MEANS FROM SAID SECOND PAIR OF OUTER DIE MEANS, SEATING SAID CORE BETWEEN SAID PORTIONS OF SAID SECOND SHELL IN SAID SEATS THEREOF, PRESSING SAID PORTIONS OF SAID SECOND SHELL INTO CONTIGUITY ABOUT SAID CORE IN ORDER TO ENCLOSE SAID CORE WITHIN SAID SECOND SHELL BY OPERATION OF SAID SECOND PAIR OF OUTER DIE MEANS THEREBY PROVIDING A BOWLING BALL VENEER, AND HEATING THE ASSEMBLAGE OF SAID CORE AND SAID VENEER AT A SUFFICIENTLY HIGH TEMPERATURE FOR A SUFFICIENTLY LONG PERIOD TO POLYMERIZE SAID OUTER SHELL AND SAID INNER SHELL, SAID SPHERICAL INSERT BEING OF A COMPOSITION THAT IS LIGHTER THAN THE COMPOSITION OF SAID FIRST SHELL, WHEREBY THE CENTER OF SAID INSERT IS DISPLACED ON ONE SIDE OF THE CENTER OF THE OUTER PERIPHERY OF SAID SECOND SHELL TO PROVIDE THE BOWLING BALL WITH TOP WEIGHT ON THE OTHER SIDE OF SAID CENTER OF SAID OUTER PERIPHERY.
