Deep cavity die burning apparatus and process

Claim 1

A METHOD OF CREATING DEEP AND SOUND CAVITIES IN A GIVEN TYPE OF WOOD WITHOUT STRUCTURALLY DAMAGING THE WOOD BOUNDING SUCH CAVITIES, SAID WOOD HAVING VOLATILE MATTER THEREIN WHICH CAN BE VIOLENTLY RELEASED AS GASES WHEN HEATED TO A HIGH TEMPERATURE WHICH WILL CAUSE HEATING DIE MEANS TO A TEMPERATURE WHICH WILL CAUSE VIOLENT RELEASE OF VOLATILE MATTER MATTER FROM SAID TYPE OF WOOD AS GASES UPON CONTACT WITH SAID DIE MEANS WITH SAID TYPE OF WOOD TO CARRY AWAY SUBSTANTIALLY FROM PRODUCTS OF THERMAL DECOMPOSITION RESULTING FROM SAID CONTACT, ENGAGING A PIECE OF SAID TYPE OF WOOD WITH SAID DIE MEANS AND MOVING SAID DIE MEANS INTO SAID PIECE OF WOOD AT A SUBSTANTIALLY CONSTANT RATE TO A DESIRED DEPTH TO PRODUCE A CAVITY, ADJUSTING THE RELATIONSHIP OF THE RATE OF INSERTION OF SAID DIE MEANS INTO A PIECE OF SAID TYPE OF WOOD AND THE TEMPERATURE OF SAID DIE MEANS IF SAID RESULTING CAVITY IS BOUNDED BY SUBSTANTIALLY ANY CHARRED MATERIAL OR CRUSHED INTO SAID PIECE OF WOOD, REPEATING SAID STEPS OF ENGAGING A PIECE OF WOOD AND ADJUSTING UNTIL A CLEAN, SOUND AND UNCRUSHED CAVITY WITH SUBSTANTIALLY NO CHARRED MATERIAL THEREIN IS OBTAINED, AND MOVING SAID DIE MEANS INTO A PIECE OF SAID TYPE OF WOOD WITH THE SELECTED RELATIONSHIP OF RATE OF INSERTION AND TEMPERATURE OF SAID DIE MEANS TO CREATE A DEEP AND SOUND CAVITY THEREIN BY CAUSING THE VIOLENT RELEAST OF VOLATILE MATTER AS GASES TO CARRY AWAY SUBSTANTIALLY ALL PRODUCTS OF THERMAL DECOMPOSITION AND PREVENT THE BUILD-UP OF CHARRED MATERIAL IN THE LAST NAMED CAVITY.

Claim 2
