Singer 404 Sewing Machine
The Singer 404 is a Slant-Needle design and all accessories must be designed specifically for this machine type. The photograph above shows the few controls. The stitch length regulator is the vertical slider. Feed dogs can be lowered for free-motion work using the control on the machine's base; this control also releases the throat plate for removal.
Bobbin winding is accomplished by releasing the hand-wheel clutch and pressing (and holding) the small rubber tire against the handwheel.
