Abstract
A reciprocating rotary tool driver is driven by a motive source which provides power to its tool through a splined shaft while the rotating tool is oscillated in a vertical mode by means of spur gear, worm gear, and crank means.
Claims9
A rotary cutter tool driver comprising
- motive means,
- a rotatable cutter tool,
- rotary drive means operatively coupling said cutter tool with said motive means,
- an oscillatory drive mechanism operatively coupled to said motive means for effecting oscillatory motion of said cutter tool during rotation thereof, said oscillatory drive mechanism including
- a pinion gear connected to said rotary drive means,
- a worm actuated by said pinion gear,
- a worm gear in operative engagement with said worm,
- crank means actuated by said worm gear, and
- means associated with said crank means, and mounted on said rotary drive means, for limiting movement of said rotatable cutter tool to oscillating motion along an axis thereof.

A rotary cutter tool driver comprising:
- motive means,
- a rotatable cutter tool,
- rotary drive means for said cutter tool operated from said motive means,
- an oscillatory drive mechanism operated from said motive means for oscillatory motion of said cutter tool during rotation thereof, said oscillatory drive mechanism including
- a pinion gear connected to said rotary drive means,
- a worm actuated by said pinion gear,
- a worm gear in operative engagement with said worm,
- crank means actuated by said worm gear, and
- means associated with said crank means to cause oscillatory motion of said rotatable cutter tool along an axis thereof,
- said crank means including a crankshaft driven by said worm gear and a crank driver element connected to said crankshaft and offset from an axis thereof,
- said means associated with said crank means to cause oscillatory motion of said rotatable tool including a sleeve mounted on said rotary drive means, and means restraining said sleeve against rotary motion and permitting movement thereof only in a vertical direction, including a substantially horizontal socket in said sleeve, said socket receiving said crank driver element to permit limited oscillatory vertical motion of said rotatable tool during actuation of said crankshaft.
8 more elements
A rotary cutter tool driver comprising
- motive means,
- a rotatable cutter tool,
- rotary drive means for said cutter tool operated from said motive means,
- said rotary drive means and said cutter tool mounted on a common axis,
- said drive means including a spur gear mounted on said axis,
- a spline gear coupled together with said spur gear on said axis, said spline gear having axially extending splines,
- a spindle mounted on said axis, said spindle including internal grooves, the splines of said spline gear mating with the internal grooves of said spindle,
- means connecting said spindle with said rotatable cutter tool,
- an oscillatory drive mechanism operated from said motive means for oscillatory motion of said cutter tool during rotation thereof, said oscillatory drive mechanism including
- a pinion gear meshing with said spur gear,
- a worm mounted on an axis of said pinion gear,
- a worm gear meshing with said worm,
- a crankshaft driven by said worm gear,
- a crank driver end mounted on an end of said crankshaft and offset from an axis thereof,
- a bearing member axially mounted on the crank driver end,
- a sleeve mounted on the axis of said rotary drive means and said cutter tool, said spindle being fixed axially within said sleeve but free to rotate as driven by said spline gear,
- a horizontal slot in said sleeve,
- and means mounted on said rotary drive means axis to restrain said sleeve against rotary motion and to permit movement thereof only in an axial direction,
- said bearing member on said crank driver end received in said slot, and said crank driver end forcing said bearing member against sides of the slot in said sleeve to cause limited upward and downward travel of said sleeve and oscillatory motion of said cutter tool during rotation thereof.
