Abstract
An improved wood working facility has a table saw which is operated in combination with a table saw extension table. The extension table is provided with an array of orifices through which air is ejected to provide a buoyant support for boards and sheet material laid atop the extension table. An ordinary shop vacuum cleaner may be utilized as the source of air being expelled from the orifices. Air may also be received from a distribution system in the shop which distributes compressed air to the various machine sites. The air is provided to an air plenum below the extension table top and exits from the plenum via the multiplicity of orifices in the top of the table. A low surface frictional veneer on the table top adds to the effort reducing efficiency of the extension table.
Claims10
An improved cutting facility comprising, in combination:
- a table saw for cutting boards and sheet stock;
- a source of air useful for clearing away wood chips and saw dust;
- a first table saw extension table for supporting said boards and said sheet stock;
- said table saw extension table having a table top having a plurality of openings therethrough;
- an air plenum beneath said table top, said plurality of openings being output orifices for air from said plenum;
- an air input for coupling air into said plenum, said source of air being coupled to said air input;
- said first table saw extension table being positioned adjacent an input end of said table saw;
- and
- at least one of said sheet stock and said board buoyantly supported by air exiting said output orifices;
- whereby said at least one of said sheet stock and said board may be readily and easily fed into said table saw and maintained at a proper cutting aspect because of said buoyant support.

- at least one of said sheet stock and said board buoyantly supported by air exiting said output orifices;
- said plurality of openings comprising output orifices for air from said plenum further comprise an array of orifices through said table top to said air plenum, said array of orifices extending from a first end zone of said table top through a central zone into a second end zone, said orifices in said array having selected diameters;
- and
- said source of air comprises a source of compressed air maintained in said cutting facility for cleaning saw dust and chips from said table saw;
- whereby said at least one of said sheet stock and said board may be readily and easily fed into said table saw and maintained at a proper cutting aspect because of said buoyant support.
