ABSTRACT:
In a spring-energized stapling machine according to the invention, some provisions are included for extending the function of the machine and preventing any harm possibly caused by the abuse of the machine. These provisions comprise a check plate which can be adjusted to obstruct the operating handle of said stapling machine, a movable fitting serving as a backing plate for paper-fastening in one state and as a safety shield to prevent the driving of staples in an other state, and which can be moved to allow conventional ejection of staples, two different systems of measuring scales engraved on both sides of the foot of said machine, and a novel staple supply which possesses two sets of grooves to accept staples of different sizes and, at its rear, means for staple removal.
