- Patent
- 274207: Lasting-Machine
- Issue date
- 1883-03-20
- Place
- Lynn, Massachusetts
- Record strength
- Medium-high patent-record strength for the lasting-machine row, with identity and immigration framing kept separate from CultureUp Indigenous Black memory claims.
- Identity evidence
- Publishable as Black participation in the U.S. patent system with a visible boundary note; not an Indigenous Black identity claim.
- Backlog priority
- 1 / not chronological rank
- Chronology caution
- Backlog priority 1 is a publication priority, not a chronological holder rank.
- Identity caution
- Use Black participation in the U.S. patent record, Suriname-born, and U.S.-based framing. Do not flatten Caribbean, immigrant, African American, and Indigenous Black memory lanes.
- Why this record matters
- The record shows how Black technical memory includes factory machinery, shoe production, and industrial labor systems.
What the public record supports
- U.S. Patent No. 274207 for a lasting-machine mechanism, issued March 20, 1883.
- The patent row supports shoe machinery and industrial-labor context.
- The profile is explicitly marked as backlog priority, not chronological rank.
What remains open
- Commercialization and assignment need deeper public source review.
- Identity language must remain boundary-aware and source-led.
