Dutton, J. Holme & H. Holme.
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.
