44 and having the axis thereof perpendicular to the axis of the first section 42 a conical thread guiding aperture 48 is axially formed in the first section 44 and tapers inwardly toward the second section 46 of the housing 42 a needle receiving slot 50 is formed in the first section 44 adjacent the second section 46 in a plane substantially normal to the axis of the first section 44 the needle slot 50 intersects the conical aperture effectively terminating the conical aperture 48 and is formed with a lead in taper 52 to aid in the insertion of the sewing needle 16 at the intersection of the conical aperture 48 and the needle slot 50 the size of the conical aperture 48 is substantially the same as the size of the needle eye 18 a groove 54 is formed in the first section 44 of the housing 42 parallel to the axis thereof and intersects the conical aperture 48 along the entire length thereof the purpose for which will be explained later the second section 46 is formed with a thread orifice 56 which intersects the needle slot 50 the orifice 56 is coaxial with the conical aperture 48 in the first section 44 and has a size substantially the same as the conical aperture 48 at the intersection thereof with the needle slot 50 the second section 46 is further formed with a cylindrical thread chamber 58 extending through the free end thereof having an axis substantially parallel to the axis of the second section 46 the orifice 56 extends inwardly to intersect the chamber 58 tangentially a bleeder orifice 60 having a diameter substantially smaller than the thread orifice 56 is formed in the second section 46 and extends from the bottom of.
