This 1868 UK patent encompasses lockstitch, chainstitch and double loopstitch designs. Fig.1 illustrates the lockstitch model, which incorporates a swivel feature in the needlebar guide h, allowing it to be turned into a horizontal position when necessary to facilitate access to the needle. However, most surviving examples seem to have dispensed with this feature.
The machine shown in Fig.19 is a friction drive chainstitch variant.
