Abstract
A universal cylinder mount for mounting a at least one of a plurality of cylinders between a headstock and a tailstock of an engraver. Each of the cylinders have a mounting aperture at each end adapted to receive a universal cylinder mount associated with each of the headstock and tailstock. The universal cylinder mount is adapted to accommodate a plurality of mounting apertures formed with different sizes and having various sloped walls for facilitating alignment and frictional gripping engagement of the cylinders.
Claims37
A universal cylinder mount comprising a base end, a nose end, and an axis of rotation, said universal cylinder mount comprising:
- support means for supporting any one of a plurality of cylinders;
- and
- engagement means on said support means for engaging a mounting aperture on said any one of said plurality of cylinders;
- said engagement means having an arcuately shaped surface wherein an associated angle is defined between said axis of rotation and a tangent line, to said arcuately shaped surface said angle increases when moving along said surface from said base and to said nose end.
A universal cylinder mount, comprising:
- a rotatable spindle comprising a base and a nose for supporting one of a plurality of cylinders;
- a plurality of engagement surfaces on said spindle for engaging a mounting aperture of said one of said plurality of cylinders;
- and
- at least one of said plurality of engagement surfaces being arcuately shaped wherein an associated angle is defined between an axis of said rotatable spindle and a tangent line, to said arcuately shaped surface whereby said angle increases when moving along said surface from said base and said nose.
A universal cylinder mount for use in an engraver to mount one of a plurality of cylinders at an engraving station of said engraver, each said cylinder having frustoconical mounting surface at each end thereof, said universal cylinder mount comprising:
- a first spindle assembly including a first spindle supported on said headstock;
- a second spindle assembly including a second spindle and a cooperating base member supporting said second spindle on said tailstock;
- a frictional engagement surface located on each of said first and second spindle assemblies;
- and
- said frictional engagement surface being generally arcuately shaped said first and second spindles each having a base and a nose, said frictional engagement surface comprising an associated angle defined by a rotation axis of said spindle and a tangent line, to said arcurated shaped surface said associated angle increases when moving along said surface from said base to said nose,
A method of mounting one of a plurality of cylinders comprising the steps of:
- providing a support for engaging a mounting surface in said one of said plurality of cylinders, said support having a generally arcuately shaped surface, wherein an associated angle is defined by an axis of rotation of said support and a tangent line, to said arcuately shaped surface said angle increases when moving along said surface from a base of said support to a nose of said support;
- and
- moving said support into engagement with said mounting surface of said one of said plurality of cylinders.
An engraver comprising:
- a headstock;
- a tailstock for cooperating with said headstock to rotatably supporting one of a plurality of cylinders where each of said plurality of cylinders comprises a first end and a second end;
- an engraving device for engraving said one of said plurality of cylinders;
- a first cylinder mount associated with said headstock;
- and
- a second cylinder mount associated with said tailstock, said first and second cylinder mounts being capable of engaging said cylinder to rotatably support said cylinder between said headstock and said tailstock;
- each of said first and second cylinder mounts comprising on arcuately shaped mounting surface;
- said arcuately shaped mounting surface of either said first cylinder mount or said second cylinder mount comprising an associated angle which is defined by an axis of rotation of said cylinder mount and a tangent line which is tangent to said arcuately shaped surface, where said associated angle increases when moving along said surface from a base of said cylinder mount to a nose of said cylinder mount.
