Sewing machine lampIn 1873, Ludwig M. Wolf of Avon, CT, patented the sewing machine lamp holder (No. 138,831). It was introduced by the Singer Sewing Machine Co. in 1876, to meet the need of those who wished to sew at night, because the lamp would not "jar off the table or upset," and it could be moved "without soiling the fingers." |
