Chaules Winfred Linscot, United States patent 1004581 (1911)
“ In the operation of this invention the tab G is connected with the clasp member N by passing the lacing string Q in any suitable fashion through the eyelets V of the former and P of the latter, and the string is drawn sufficiently tight as to affect the desired amount of constriction, and the string is then tied. The advantage of uncoupling the tabs by means of the clasp device is apparent in view of the fact that re-lacing, or a readjustment of the lacing becomes unnecessary when a temporary release from the tension of the tabs is desired. ”
