Abstract
A lubricated hair clipper drive system includes a clipper frame with a pair of opposed arms separated by a drive space, a drive shaft reciprocating laterally between the arms at high speed, a drive member receiving motive power from a power source and secured to the shaft for common reciprocation within the drive space, and a lubricant reservoir and applicator disposed on the shaft between the drive member and a corresponding one of the arms.
Claims11
A lubricated hair clipper drive system, comprising:
- a clipper frame having a pair of opposed arms defining a drive space therebetween;
- a drive shaft reciprocating laterally relative to said arms at high speed;
- a drive member receiving motive power from a power source and secured to said shaft for common reciprocation in said drive space;
- a lubricant applicator disposed on said shaft between said drive member and a corresponding one of said arms;
- and
- wherein said applicator is constructed and arranged to frictionally engage and be movable with said shaft when said hair clipper is in a start up condition, and through operation of said drive member, is compressed against said corresponding arm when said hair clipper is in a fully operational condition, allowing relative sliding of said shaft relative to said applicator.

A lubricated hair clipper drive system, comprising:
- a clipper frame having a pair of opposed arms defining a drive space therebetween;
- a drive shaft reciprocating laterally relative to said arms at high speed;
- a drive member receiving motive power from a power source and secured to said shaft for common reciprocation in said drive space;
- a lubricant applicator disposed on said shaft between said drive member and a corresponding one of said arms;
- and
- wherein said applicator is constructed and arranged to have an axial width W in a start up condition with said drive member in a mid-arm position, said width extending more than half a distance on said drive shaft between said drive member and an inner surface of said arm, and said applicator is constructed and arranged to be compressed against an inner surface of said corresponding arm through reciprocal movement of said drive shaft and said drive member and having a compressed width which is less than said axial width.

A lubricated hair clipper drive system, comprising:
- a clipper frame having a pair of opposed arms defining a drive space therebetween;
- a drive shaft reciprocating laterally relative to said arms at high speed;
- a drive member receiving motive power from a power source and secured to said shaft for common reciprocation in said drive space;
- a lubricant applicator disposed on said shaft between said drive member and a corresponding one of said arms, and
- wherein said applicator is constructed and arranged so that upon said clipper reaching an operational condition, the applicator is compressed and pumps lubricant to said shaft, and upon said clipper being turned off and said drive member moving to a position releasing pressure on said applicator, said applicator reverts to a rest condition and absorbs lubricant from said shaft.
