US Patent No. 934,914, granted 21 September 1909 to Charles Hickton of Long Eaton, England, for an improvement to twist lace machines of the Levers and go-through types. The invention moves the catch bar endwise together with the comb bar, so the lace carriages are not bent or strained when traversed to equalize yarn lengths drawn from the bobbins. It has one sheet of drawings (Figs. 1-5), a specification and five claims.
