The first machine to combine all the disparate elements of the previous half-century of innovation into the modern sewing machine was the device built by English inventor John Fisher in 1844, a little earlier than the very similar machines built by Isaac Merritt Singer in 1851, and the lesser known Elias Howe, in 1845. However, due to the ...
For this hybrid machine he received patent US 8296, issued 1851-Aug-12 , (reissued as RE914 on 28 February 1860). Knowing that such a machine would surely lead to patent litigation with his former partners who had bought out the patent for the vibrating shuttle, Wilson kept working, and developed a refined design which kept the bobbin ...
A free arm houses the machine's feeder and bobbin driver in a tubular arm-shaped bed, enabling material to be wrapped around the mechanism during sewing rather than simply resting on top of it. A free arm greatly simplifies sewing tasks like darning and hemming on delicate fabrics and difficult-to-reach seams—uses for which Elna was heavily ...
The upper thread runs from a spool kept on a spindle on top of or next to the machine, through a tension mechanism, through the take-up arm, and finally through the hole in the needle. Meanwhile, the lower thread is wound onto a bobbin, which is inserted into a case in the lower section of the machine below the material.

[2] His first machine formed a lock stitch by means of a curved needle on a vibrating arm above the cloth plate, and a reciprocating two-pointed shuttle traveling in a curved race below the plate.
