This thread tension gauge, or tensometer, was used to measure the tension, or tensile force, in the rapidly moving thread of a sewing machine. Too much tension leads to thread breakage, while too little tension causes other problems. This unit was developed by the H. F. Livermore Corporation in Boston, founded in 1887.
