chainstitch

This was the first American patent for a chainstitch machine.

The machine (fig. 8) made a chainstitch by means of a barbed or hooked needle.

This machine made the chainstitch, using not one but many hooked needles that operated simultaneously.

At this time the machine was described as making a “double lock stitch” (another name for the double chainstitch).

Blake formed a chainstitch by using a hooked needle, which descended from above, to draw a thread through the supporting arm.
