Abstract
Abstract A burning table having a pan with a sloping bottom terminating in a clean-out trough. The water level in the table is controlled by over-flow pipes, one of which is valved to permit lowering the water level below the grating which catches the torch cut parts and the other of which controls the maximum water level necessary for burning but which is manually removable to permit complete draining of the pan and clean-out trough. A spray header extends along the pan opposite the clean-out trough and sprays water at high pressure through nozzles to wash debris resulting from the burning operation into the clean-out trough upon closing the valved over-flow pipe for filling the pan to the maxium water level necessary for burning. Bars for supporting the plate to be cut are mounted to minimize warpage and damage from the flame and to be readily replaceable.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
152 words
A burning table for supporting a metal plate for cutting thereof comprising: a pan capable of retaining water and having a bottom which slopes toward one end thereof, thereby defining a high side and a low side; a clean-out trough formed along the low side of the pan; a grating supported within said pan and being substantially level; a spray header positioned below said grating and extending along said high side; said header being capable of directing water under pressure along the bottom of the pan toward said trough to wash debris into said trough; means for supporting said metal plate above the grating; and water level control means for selectively maintaining water within the pan at a first level above the grating during the flame cutting operation and at a second level below the grating to permit removal of parts which drop onto the grating after being cut from said plate.
Claim 2
Dependent Claim
152 words
A burning table for supporting a metal plate for cutting thereof comprising: a pan capable of retaining water and having a bottom which slopes toward one end thereof, thereby defining a high side and a low side; a clean-out trough formed along the low side of the pan; a grating supported within said pan and being substantially level; a spray header positioned below said grating and extending along said high side; said header being capable of directing water under pressure along the bottom of the pan toward said trough to wash debris into said trough; means for supporting said metal plate above the grating; and water level control means for selectively maintaining water within the pan at a first level above the grating during the flame cutting operation and at a second level below the grating to permit removal of parts which drop onto the grating after being cut from said plate.
Claim 3
Dependent Claim
37 words
A burning table according to claim 1, wherein said water level control means is capable of draining substantially all of said water from said pan, including said trough, to permit removal of accumulated debris from said trough.
Claim 4
Dependent Claim
40 words
A burning table according to claim 1, wherein said means for supporting said metal plate comprises a plurality of metal bars extending across said pan and above said grating at an elevation higher than said first level of the water.
Claim 5
Dependent Claim
23 words
A burning table according to claim 3, and further comprising; positioning means for loosely retaining each of said metal bars above said grating.
Claim 6
Dependent Claim
87 words
A burning table according to claim 4, wherein; said metal bars have a rectangular cross-section with a major dimension and a minor dimension; and each of said positioning means comprises a pair of metal angle irons positioned back to back and spaced apart a distance to slidably receive the minor dimension of each of said bars and position the major dimension thereof in a vertical plane; the metal bars extending above the water and the angle irons being entirely below the water at said first level thereof.
Claim 7
Dependent Claim
23 words
A burning table according to claim 5, wherein said grating comprises a plurality of sections with each section resting upon the angle irons.
Claim 8
Dependent Claim
75 words
A burning table according to claim 1, wherein said water level control means comprises a first over-flow pipe in said pan with an opening above the level of the grating; a second over-flow pipe in said pan with an opening below the level of the grating; a drain line communicating with said first and second pipes; a valve associated with said second pipe to selectively communicate and isolate said second pipe with said drain line.
Claim 9
Dependent Claim
64 words
A burning table according to claim 7, and further comprising; a third over-flow pipe connected to and in sealing engagement with the bottom of said trough and having a threaded opening at a level to permit draining substantially all of the water; and said first pipe is threadedly engageable with said third pipe for selective removal and connection of said first and third pipes.
Claim 10
Dependent Claim
159 words
A burning table to facilitate the cutting of metal plates comprising: a pan capable of retaining water and having a sloping bottom defining a high side and a low side; a clean-out trough formed along the low side of the pan; a grating supported within said pan and being substantially level; a spray header positioned below said grating and extending along said high side; means for supporting said metal plates above the grating; a first over-flow pipe in said pan with an opening above the level of the grating; a second over-flow pipe in the pan with an opening below the level of the grating; a sump; drain line means connecting each of said first and second pipes with the sump; a valve associated with said second pipe to selectively connect and interrupt communication between said second pipe and the sump; and a high-pressure pump connected to draw water from the sump and discharge it through the spray header.
Claim 11
Dependent Claim
159 words
A burning table to facilitate the cutting of metal plates comprising: a pan capable of retaining water and having a sloping bottom defining a high side and a low side; a clean-out trough formed along the low side of the pan; a grating supported within said pan and being substantially level; a spray header positioned below said grating and extending along said high side; means for supporting said metal plates above the grating; a first over-flow pipe in said pan with an opening above the level of the grating; a second over-flow pipe in the pan with an opening below the level of the grating; a sump; drain line means connecting each of said first and second pipes with the sump; a valve associated with said second pipe to selectively connect and interrupt communication between said second pipe and the sump; and a high-pressure pump connected to draw water from the sump and discharge it through the spray header.
Claim 12
Dependent Claim
88 words
A burning table according to claim 9, wherein said means for supporting comprises: a plurality of metal bars extending across said pan, each of said bars having a rectangular cross-section defining a major dimension and a minor dimension; a pair of angular members secured to position each of said bars, said pair of members being spaced to slidably receive said minor dimension of each said bar and maintain the major dimension thereof vertical; and said grating being in sections capable of resting upon facing members of adjacent pairs.
