Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
81 words
A GEAR GENERATOR COMPRISING A FRAME, A WORK SPINDLE ROTATABLE IN A WORK HEAD ON THE FRAME, A CRADLE CARRYING A ROTARY CUTTING TOOL AND ROTATABLE IN A CRADLE HOUSING THAT IS RECIPROCABLE ON THE FRAME TO ADVANCE AND WITHDRAW THE CRADLE RELATIVE TO THE WORK SPINDLE, THE DIRECTION OF SUCH RECIPROCATION BEING IN A PLANE PARALLEL TO BOTH THE WORK SPINDLE AND THE CRADLE ROTATION AXIS, AND THE CRADLE ROTATION AXIS BEING INCLINED TO SAID DIRECTION BY AN ACUTE ANGLE.

Claim 3
Independent Claim
155 words
THE METHOD OF GENERATING GEARS WITH TAPERING TOOTH SLOTS, WITH A ROTARY TOOL HAVING OPPOSITE SIDE CUTTING SURFACES REPRESENTING THE OPPOSITE SIDES OF A TOOTH OF A GENEATING GEAR WHICH ARE COAXIAL SURFACES OF REVOLUTION, WHICH COMPRISES GENERATING ONE SIDE OF THE TOOTH SLOT OF A WORK GEAR WITH ONE SIDE CUTTING SURFACE OF THE TOOL BY ROTATION OF THE WORK GEAR ABOUT ITS AXIAL AND SIMULTANEOUS ROTATION OF THE TOOL ABOUT THE AXIS OF THE GENERATING GEAR, THEN SHIFTING THE WORK GEAR IN A DIRECTION PERPENDICULAR TO THE AXIS OF THE GENERATING GEAR AND ROTATING THE WORK GEAR ABOUT ITS AXIS TO POSITION THE OPPOSITE SIDE CUTTING SURFACE OF THE TOOL FOR CONTACT WITH THE OPPOSITE SIDE OF THE TOOTH SLOT, AND THEN GENERATING SAID OPPOSITE SIDE OF THE TOOTH SLOT BY REVERSE ROTATION OF THE GEAR ABOUT ITS AXIS AND SIMULTANEOUS REVERSE ROTATION OF THE TOOL ABOUT THE AXIS OF THE GENERATING GEAR.
