Abstract
Apparatus for locking a drafting board in a desired attitude of angular adjustment enables adjustment of the drafting board through a full ninety degree movement. Force is selectively applied by a control system to interdigitating brake leaves to hold the drafting board surface from rotating once the desired angle has been achieved, and is selectively released to enable angular adjustment. Provision is made to adjust the control system of the apparatus responsive to the particular geometry of the drafting table.
