ABSTRACT:
This disclosure relates to a sewing machine lubrication system including positive displacement mechanisms adapted to transmit lubricant under pressure to the operating mechanisms of the machines and for transferring lubricant collected in non-drainable areas of the machine to the lubricant reservoir. Arranged in combination with the displacement mechanisms is a filtering/distribution assembly which serves to individually and selectively supply a relatively small, but sufficient quantity of lubricant to the operating mechanisms according to the requirements thereof. The present invention further provides a pressure relief valve assembly for selectively regulating the pressure in the lubrication system.
