Patent Overview — US 108,536

Title: "Edwaed b" (as listed on the Google Patents page; the specification heading reads "Improvement in Bee-Hives")

Inventor: Edward B. Turnipseed, M.D., of Columbia, South Carolina

Patent number: US 108,536

Dates: Letters Patent dated October 18, 1870; prior art date October 18, 1870; publication October 18, 1870; anticipated expiration October 18, 1887. Legal status listed as "Expired – Lifetime."

Assignee: None stated in the supplied text.

Purpose: To provide an improved bee-hive that protects bees from the moth and keeps the hive floor clean, while allowing the interior to be inspected and drawers to be removed independently.

Plain-language scope (per the single claim): The claim covers a hive made up of a wooden frame (base a, posts a, shelves a²), drawers B, B¹, B² — drawer B having a wire bottom (labeled b in the drawing description) — and enameled-cloth siding G attached by buttons c, all constructed and arranged for the purpose specified. The described advantages are: drawers usable independently and removable one at a time without disturbing the others; a wire-cloth bottom that causes moth eggs carried on bees' feet, and chips or webbing debris, to fall through beneath the hive; and removable enameled-cloth sides for easy inspection. The components are said to be put together with screws so they may be taken apart.

What the excerpt does not establish: The supplied text provides no filing date, application number, or assignee/ownership information, and the OCR of the specification is incomplete in places (for example, parts of the background paragraph are missing). The title as indexed ("Edwaed b") is apparently a transcription artifact and should be read literally as given. No information on litigation, ownership transfers, validity, or comparison to the listed similar documents is available from this source, and none is asserted here.

Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
