providing full fan-suction connection to a cooler box at all points in its track travel
judge verdicts (2)
- groundedness 0.85 pass — The claim is well-supported by the passage. The passage states that the Burns flexible-arm cooler provides 'full fan-suction connection to a cooler box at all points in its track travel' for roasted batches. The only minor issue is that the passage dates the patent to 1917, not specifying it was granted in 1917, though this is a reasonable interpretation from the context.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The quote is accurate and supports the claim. However, there is one issue: The time qualifier shows 'when': '1917' with valid_from and valid_to both as '1917', but the passage states the patent was granted in 1917 to 'Richard A. Greene and William G. Burns' - this is correctly dated. The minor deduction is for the time specification being overly restrictive (using a single year 1917 for both valid_from and valid_to) when the passage only explicitly states the patent grant date of 1917 without indicating an end date, though this is a minor issue. The viewpoint should arguably be 'passage' or reference the patent grant context rather than 'author', but the statement itself accurately reflects what the passage attributes. All other qualifiers (stance, sentiment, context for 'roasted batches') are faithful to the passage.

judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The quoted text explicitly states that Richard A. Greene (along with William G. Burns) were granted patents in the United States on the Burns flexible-arm cooler in 1917, which exactly matches all elements of the claim.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint 'author' is appropriate as the passage itself makes the assertion without attribution to a named source. The stance 'asserts' correctly reflects the passage's straightforward presentation. The sentiment 'neutral' matches the passage's factual tone. The time '1917' is accurate per the passage. The context is appropriately empty as the passage provides no restricting sense or role beyond the technical specification. The quote is verbatim and directly supports the claim.

- groundedness 0.70 pass — The claim is directly supported by the passage, which states that William G. Burns (along with Richard A. Greene) 'were granted patents in the United States on the Burns flexible-arm cooler' in 1917. The only minor rewording is that the claim uses 'was granted patent on' (singular) while the passage uses 'were granted patents' (plural), but this is a negligible distinction that doesn't affect the core factual accuracy.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint is correctly set to 'author' (the passage itself states this as fact, not attributed to a named source). The stance, sentiment, time (1917), and quote are all accurate and faithful. The context is appropriately empty since the passage does not restrict the claim to a particular sense or role. Minor deduction: the claim's predicate uses 'was granted patent on' while the passage uses the plural 'were granted patents' - a minor technical distinction in that the passage mentions Greene and Burns together as co-grantees, though the claim focuses on Burns individually. This is a negligible fidelity issue given the overall accuracy.
