In Shrlock Holmes's short story, The Adventure of the Pince-Nez, while there is a heavy rain outside, Holmes and Watson receive a sudden visitor in their house at a late hour of the night. After discovering that the visitor is the young detective, Hopkins, Watson says:
The detective mounted the stairs, and our lamp gleamed upon his shining waterproof. I helped him out of it while Holmes knocked a blaze out of the logs in the grate.
The second part of the second sentence seems so ambiguous for me. What is meant by knocking out here? Is it extinguishing a fire in the logs?

    No, it refers to "producing" a blaze. It's a similar construction to "get something out of someone".

    He moved and knocked the logs around so as to get the fire to burn more strongly, by making it "come out" more.

    I'm guessing the main effect of doing that is getting more oxygen to the fire so it can burn more hotly again, and flame up.
