Abstract

IN A MECHANICAL PENCIL, A TUBULAR LEAD RESERVOIR (5) IS CONNECTED TO THE REARWARD END OF A LEAD CHUCK (4). A CYLINDRICAL WEIGHT (8) IS FITTED SLIDABLY AROUND THE LEAD RESERVOIR (5) AND IS ADAPTED TO STRIKE AGAINST THE CHUCK (4) TO OPEN THE SAME TO ALLOW FORWARD FEED OF THE LEAD WHEN A FORWARD SHAKE IS APPLIED TO THE PEN BARREL (2). IN ORDER TO PREVENT FORWARD FEED OF THE LEAD AS A RESULT OF UNINTENDED FORWARD SHAKE WHILE CARRYING THE PENCIL, A SLIDER (10) DISPOSED REARWARDLY OF THE LEAD RESERVOIR HAS A RADIALLY OUTWARDLY EXTENDING ENGAGEMENT PROJECTION (10A) WHICH IS ADAPTED TO SLIDABLY ENGAGE EITHER A LONGITUDINAL GUIDE SLOT (2A) IN THE PEN BARREL (2) OR A LATERAL SLOT (2B) CIRCUMFERENTIALLY AND REARWARDLY EXTENDING IN THE PEN BARREL. WHEN THE ENGAGEMENT PROJECTION (10A) IS IN ENGAGEMENTWITH THE LATERAL SLOT (2B), THE CHUCK (4) IS CAUSED TO TAKE AN ADVANCED POSITION IN WHICH THE CHUCK IS OPEN SO THAT A FORWARD STROKE CANNOT FEED THE LEAD FORWARD.(FIG 2)
