1852 Bradeen's Patent Model of a Sewing Machine

<< >>
Sewing Machine Patent Model
Patent No. 9,380, issued on November 2, 1852
John G. Bradeen of Boston, Massachusetts
John G. Bradeen notes in his patent specification that his sewing machine operates and forms a similar stitch to that of Frederick R. Roberson’s sewing machine of December 10, 1850 (Patent No. 7,824.) Roberson’s machine sewed with a running stitch or basting stitch.
The mechanisms of Bradeen’s patent model are mostly made of brass and the model sits on a simple wooden box. He furnished six pages of drawings depicting his improvements, whereas most sewing machine inventors limited their submissions to fewer drawings. Bradeen claims for his improvements “two rotating draft-hooks . . . separate from the needle, in combination with the two needles and two threads-guides; . . . the arrangement of each needle and its thread-guide, respectively, on opposite sides of the cloth . . . and the combination of the rocking thread-lifter or its equivalent with the needle and presser . . . .”
It is not known if any sewing machines were manufactured based on Bradeen’s patent.
