Abstract
A yarn spinner has two spaced apart upstanding posts whose upper ends each have a slot for receiving and journalling opposite ends of a spindle shaft. A flyer formed by a wire constituting a guide has a loop formed in it through which spun yarn is diverted to a distributor. The distributor is a v-shaped spring clip having a hole in each side for passing over the guide wire and a ring is suspended in the apex of the V through which the yarn is threaded for diverting it to a bobbin on the spindle. Pressing the sides of the spring clip toward each other releases it for movement on the guide wire and releasing the sides re-engages it with the wire. A tensioner line running over the bobbin has a rubber band in it and a capstan allows winding and unwinding line to increase and decrease the stretch of the rubber band to corresponding change the frictional drag on the bobbin.
