Abstract
Abstract A link and flight assembly for a blast chamber conveyor is disclosed. The assembly includes a flight having a first surface formed of blast resistant materials, such as manganese. The flight is T-shaped in cross-section and is connected to the link by a mounting arm secured to the portion of the flight which is not subjected to blasting. This permits the use of inexpensive materials to join the link to the flight bar.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
A link and flight assembly for a blast cabinet conveyor comprising: (a) a flight having a first element thereof formed of material which is highly resistant to blast treatment and a backer bar secured behind the flight; (b) a pair of links including means for interengaging other links to form a conveyor belt of link and flight assemblies and means for securing said links to both ends of said flight only to said backer bar, said securing means including a mounting plate adapted to be releasably secured to said backer bar; a mounting arm connecting said plate to said link, whereby only said first element of the flight need be formed of blast resistant material, the links, backer bar and securing means being formed of lower cost, less blast resistant materials.
Claim 2
Dependent Claim
131 words
A link and flight assembly for a blast cabinet conveyor comprising: (a) a flight having a first element thereof formed of material which is highly resistant to blast treatment and a backer bar secured behind the flight; (b) a pair of links including means for interengaging other links to form a conveyor belt of link and flight assemblies and means for securing said links to both ends of said flight only to said backer bar, said securing means including a mounting plate adapted to be releasably secured to said backer bar; a mounting arm connecting said plate to said link, whereby only said first element of the flight need be formed of blast resistant material, the links, backer bar and securing means being formed of lower cost, less blast resistant materials.
Claim 3
Dependent Claim
30 words
The assembly according to claim 1 wherein said backer bar is secured in perpendicular relation to said first element to form a flight which is generally T-shaped in cross section.
Claim 4
Dependent Claim
32 words
The assembly according to claim 2 wherein said backer bar has a plurality of mounting holes provided therethrough and said securing means engages said holes to secure the links to each flight.
Claim 5
Dependent Claim
123 words
A link and flight assembly for a blast cabinet conveyor comprising: (a) a flight including a blast resistant surface and a backer bar secured behind the flight in perpendicular relation thereto; (b) a pair of links including means for interengaging other links to form a conveyor belt of link and flight assemblies and means for securing said links to both ends of said flight only to said backer bar, said securing means including a mounting plate adapted to be releasably secured to said backer bar; a mounting arm connecting said plate to said link, whereby only said blast resistant surface need be formed of blast resistant material, the links, backer bar and securing means being formed of lower cost, less blast resistant materials.
