Abstract

A carving cabinet configured to enable carving of the work-piece outside the main machine cabinet, without requiring the work-piece to be completely wrapped in a protective covering. The carving cabinet includes a housing defining an enclosure for operating the carving tool when carving the work-piece. A barrier member is coupled to the housing and is configured to substantially separate the work-piece from the enclosure when carving the work-piece. The barrier member includes a first surface facing toward the enclosure and an opposing second surface facing away from the enclosure. A carving port extends between the first surface and the second surface. The barrier member is configured to allow the work-piece to be disposable adjacent the second surface to enable carving of the work-piece through the carving port.

Claims

1. An abrasive blasting cabinet for carving a work-piece with an abrasive blasting tool, the abrasive blasting cabinet comprising:

a housing having;

a front wall;

a rear wall in opposed relation to the front wall;

a pair of sidewalls extending between the front wall and the rear wall;

an attachment panel extending between the front wall and the rear wall and being located between the pair of sidewalls, the attachment panel having an opening formed therein;

the housing defining an enclosure for operating the abrasive blasting tool when carving the work-piece, and a vestibule being sized and configured to at least partially receive the workpiece, the vestibule being at least partially defined by the front wall, the rear wall and the attachment panel, the enclosure and the vestibule being at least partially separated by the attachment panel; and

a barrier member attachable to the attachment panel so as to substantially extend across the opening in the attachment panel, the barrier member including;

a first surface facing toward the enclosure;

an opposing second surface facing away from the enclosure; and

a carving port extending between the first surface and the second surface;

the barrier member being configured to allow the work-piece to be disposable adjacent the second surface such that the work-piece does not extend through the carving port, and a portion of the work-piece extends across the carving port to enable carving of that portion of the work-piece extending across the carving port through the interaction of the carving tool on the work-piece through abrasive blasting port.

2. The abrasive blasting cabinet recited in claim 1, further comprising a viewing window coupled to the housing to enable viewing into the enclosure.

3. The abrasive blasting cabinet recited in claim 1, further comprising a working port formed in the housing and configured enable a user to reach into the enclosure.

4. The abrasive blasting cabinet recited in claim 3, wherein the working port is formed in a panel configured to be detachably connected to the housing.

5. The abrasive blasting cabinet recited in claim 1, wherein the barrier member is detachably coupled to the housing.

6. The abrasive blasting cabinet recited in claim 1, wherein at least a portion of the barrier member is formed from a flexible material.

7. The abrasive blasting cabinet recited in claim 6, wherein at least a portion of the barrier member is formed from a rubber material.

8. The abrasive blasting cabinet recited in claim 1, wherein at least a portion of the barrier member is configured to be disposable in tension when the work-piece is disposed adjacent the second surface.

9. The abrasive blasting cabinet recited in claim 8, wherein the barrier member is configured to form a seal with the work-piece when the work-piece is disposed adjacent the second surface of the barrier member.

10. The abrasive blasting cabinet recited in claim 1, wherein the barrier member includes a molded portion sized and configured to be complimentary to the work-piece.

11. The abrasive blasting cabinet recited in claim 10, wherein the barrier member is formed of urethane.

12. The abrasive blasting cabinet recited in claim 1, wherein the barrier member is formed from a rigid material.

13. The abrasive blasting cabinet recited in claim 12, wherein the barrier member is formed from a metal material.

14. The abrasive blasting cabinet recited in claim 1, further comprising a curtain coupled to the housing and at least partially extending over the barrier member.

15. The abrasive blasting cabinet recited in claim 1, wherein the barrier member is configured such that entirety of the work-piece remains outside the enclosure defined by the housing while the abrasive blasting tool interacts with the work-piece.

16. The abrasive blasting cabinet recited in claim 1, the vestibule being sized and configured to receive the entire work-piece for carving of the work-piece.

17. A method of carving a work-piece, the method comprising the steps of:

placing a work-piece adjacent an abrasive blasting cabinet for carving the work-piece with an abrasive blasting tool, the abrasive blasting comprising;

a housing having;

a front wall;

a rear wall in opposed relation to the front wall;

a pair of sidewalls extending between the front wall and the rear wall;

an attachment panel extending between the front wall and the rear wall and being located between the pair of sidewalls, the attachment panel having an opening formed therein;

the housing defining an enclosure for operating the abrasive blasting tool when carving the work-piece, and a vestibule being sized and configured to at least partially receive the workpiece, the vestibule being at least partially defined by the front wall, the rear wall and the attachment panel, the enclosure and the vestibule being at least partially separated by the attachment panel; and

a barrier member attachable to the attachment panel so as to substantially extend across the opening in the attachment panel, the barrier member including;

a first surface facing toward the enclosure;

an opposing second surface facing away from the enclosure; and

a carving port extending between the first surface and the second surface;

the work-piece being placed adjacent the second surface; and

directing abrasive blasting media from the abrasive blasting tool to the work-piece through the carving port.

18. The method recited in claim 17, wherein the work-piece is placed adjacent the second surface such that no portion of the work-piece extends completely through the carving port and into the enclosure.

19. The method recited in claim 17, wherein the entirety of the work-piece remains outside of the enclosure during the directing step.
