F.N.Cookson.

Cookson's second patent dates from 1886. His design at this stage incorporated a built-in table clamp. The shuttle drive was actuated by a bell-crank using a connecting rod - this being a modification from his first concept which used an over-fussy rack and pinion system. This second patent acknowledges that a horizontal shuttle race could be substituted. Indeed, his penultimate design of 1887 includes just this. However, a vertical arc shuttle motion is re-employed in the final design, this being powered by a simple crank and connecting rod.
