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.
