US Patent 1,647,798, granted 1 November 1927 to Samuel Tomlinson Hall of West Bridgford, England, assignor to Henry Gamble. It describes a pattern mechanism that lets a plain net curtain twist lace machine produce patterned fabric by adding guide bars that shog extra patterning threads. The mechanism uses a stepped cam wheel, gravity-pivoted arms, a stepped rod and a bell-crank lever to shog quickly so the thread does not foul the bobbin carriages. The document has two sheets of drawings, the specification and ten claims.
