ABSTRACT:
A support structure is provided for a sewing machine needle. The structure includes a simplified needle bar 14 having a solid end 34 with a transverse, threaded hole 36. A die cast needle clamp 11 is precision-formed with a hollow cylinder 13 that fits over the end of the bar and is attached by a screw 16. A needle channel 19 is cast in the clamp to hold the shank 22 of a needle with the flat surface of the shank against a flat surface 21 of the channel and the round part of the shank captured between another flat surface 32 and the conical end of a screw 23. The cross section of the channel 19 is large enough to receive standard needles but not so large as to receive the shank of the smallest standard needle improperly oriented.
