"The Norton Anthology of American Literature" - autobiography of Nathaniel Hawthorne. Citation: "(One of his stories) reached print in its narrative frame, but the editor of the 'New-England Magazine' scrapped the frame for "Young Goodman Brown" and others that are now known as isolated items instead of interrelated elements in a larger whole."
I know almost nothing about Hawthorne's writing but here's how I see it.
The editor of the magazine decided to print these stories as individual items rather than present them as parts of a larger "narrative frame". In doing so, he "scrapped" (discarded, removed) this connecting framework.
So the meaning here is to scrap, discard, reject, remove.
The past tense of "scrape" is "scraped": "He scraped some butter onto his toast with a small knife". "The chair legs scraped the floor as she stood up".
