Abstract
A metering device for a sewing machine for supplying a predetermined length of material to the stitch forming instrumentalities. Movement is imparted to the metering device by a series of one way clutch assemblies, one of which is operably connected to a drive mechanism of the machine. A motion transfer mechanism provides for opposite movement in unison of the clutch assemblies so that any movement of the drive mechanism results in a feeding displacement of the metering device. A brake assembly applies a symetrical frictional force to one of the feed rollers so as to prevent overthrow of the device.
