Frederick McKinley Jones and the mobile refrigeration patent record

Jones's vehicle air-conditioning patent belongs in CultureUp's systems lane because it connects mobile refrigeration, co-invention, corporate assignment, and public logistics memory.

Why this belongs on CultureUp

Jones is a public-record memory story.

This belongs on CultureUp because the patent record connects invention to place, public institutions, work systems, laboratories, employers, federal or corporate assignment, and the limits of public records.

Patent: 2303857: Air Conditioner for Vehicles
Issue date: 1942-12-01
Place: Minneapolis, Minnesota
Record strength: Patent-record facts are attached with at least one public context source. CultureUp still separates patent proof from biography, adoption, commercialization, and identity claims.
Identity evidence: Public context source attached where available; CultureUp does not use the patent row alone as race, ancestry, lineage, or Indigenous Black identity proof.
Sprint priority: 3 / not final rank
Cluster: 20th-century systems
Co-inventors: Joseph A. Numero
Assignee: U.S. Thermo Control Co. / corporate assignee
Needed before promotion: Promotion language should remain limited until source-led context, assignment, co-inventor, and commercialization review is complete.
Why this record matters: The route shows how Black patent memory enters mobile cold-chain systems, wartime logistics memory, co-invention, and company assignment.

Article profile

Read the person, place, invention, and record separately.

CultureUp keeps each layer visible so a patent record does not get stretched into claims the source trail cannot support.

The patent record

2303857 was issued on 1942-12-01 for Air Conditioner for Vehicles. The route preserves Joseph A. Numero as co-inventor. The route also names U.S. Thermo Control Co. as corporate assignee, because inventor status and assignment are different public-record facts.

The person in the record

The attached public context sources support a reader-facing profile frame. Any deeper life history, family record, school record, employment file, or community memory needs its own source trail.

Place attached to the claim

Minneapolis, Minnesota is the public place anchor used for this route. CultureUp does not infer local family continuity from the patent row alone.

The invention

The invention is summarized from the public patent title and source trail. Technical, market, institutional, and adoption claims stay limited to what the attached sources can support.

Business, labor, and use

Modern patent records often separate inventor, employer, assignee, licensee, and beneficiary. CultureUp keeps those categories apart instead of treating a patent as proof of ownership, wealth, adoption, or public impact.

What the record cannot prove

The patent record does not by itself prove full biography, race, ancestry, Indigenous Black identity, commercialization, institutional adoption, economic benefit, modern product lineage, or community memory.

Identity and correction note

CultureUp treats this as Black American patent memory only through public, reviewable sources. The page does not certify ancestry, descent, tribe, nationality, family history, or private identity.

Send stronger patent images, assignment records, employer records, licensing documents, public biographies, or source corrections through CultureUp's correction path.

Patent records do not prove final rank, private identity, solo credit when co-inventors appear, employment ownership, commercialization, adoption, or later public impact.

Indexable as a source-led Sprint 5 profile with visible source limits.

Employer, assignee, and inventor status are not interchangeable. CultureUp names assignees when the patent record does.

Do not use this page to make absolute first, ownership, adoption, or commercialization claims without a separate source trail.
