U.S. Patent 1,648,792 — 'Bottle-forming machine' (Albert F. Tremblay, 1927)

• Inventor: Albert F. Tremblay (individual assignee) — resolves the vault’s “A. F. Tremblay” / “Harold Trembley” / “Trembley” variance to Albert F.
• Filed: June 26, 1926. Granted: November 8, 1927. Title: “Bottle-forming machine.”
• Design: a rotating/“spider” machine — hollow pedestal, multiple mold stations around the circumference, a hollow rotating arm holding interchangeable blank and finishing molds. Sequence: blank mold receives molten glass -> plunger forms the initial cavity (parison) -> compressed air blows the preliminary shape -> transfer to the finishing mold for the final blow. An automatic blow-and-blow (press-and-blow-capable) rotary forming machine.
• Stated goal: “compact, circular machine … utilizing hollow structural components to allow cooling air circulation and reduce overall weight and friction, enabling higher operational speeds than contemporary machines” — i.e. explicitly pitched as faster/cheaper/simpler than the Hartford-Empire-controlled machines an independent could not easily license.
• Corroboration + nuance: confirms the vault’s bill-of-sale claim (patent 1,648,792, $6,000). BUT filed 1926/granted 1927 vs. Three Rivers’ automated equipment coming online ~early 1925 means the machine ran ~1-2 years before the patent issued. The existing articles’ phrasing “a patented bottle-blowing machine” should be read as “later-patented”; the bill of sale citing the number would postdate issuance (1927+).
