ABSTRACT:
This disclosure relates to a device that is adapted to individually and simultaneously guard and cool each needle of a sewing machine. The device includes an apertured member that is adjustably secured to the frame of the machine in a position below the work support of the machine. The apertured member is adapted to receive the needle or needles during the lower portion of its stroke. The diameter of the needle receiving aperture or bore provides a camming or guarding surface against which the needle may impinge, in the event that on its downstroke the needle is deflected or bent in any direction away from its recipricatory path. A passageway, formed in the member, allows for the transmission of a cooling medium to the needle receiving bore so as to cool the eye area and point of the needle as it passes therethrough.
