Abstract
A combined pump and oil reservoir and oil delivery apparatus directs oil to the internal chambers of a portable sewing machine where oil is distributed by pump pressure, gravity flow, capillary action, wicking, misting and movement of machine components. Oil is pumped into a manifold leading to upper and lower main drive shaft bearings and to the needle driving assembly for subsequent dispersion during rotation and reciprocation of machine parts to fling such oil outwardly within the internal chambers to oil machinery both directly and by misting.
