Brush construction including movably-mounted bristles

A brush, comprising:

• a handle at one end, and a brush head at the opposite end connected to the handle by a yielding coupling;
• a plurality of bristle holders each rotatably mounted in the brush head about its own rotary axis;
• a plurality of crank arms each coupled to one of said bristle holders for oscillating it about its respective rotary axis, each of said crank arms being formed with an elongated slot;
• a reciprocatable rod fixed to said handle so as to be reciprocated therewith with respect to said brush head during manual reciprocation of the handle by a user when using the brush, said rod carrying a plurality of pins each received in the slot of one of said crank arms to oscillate the respective bristle holder about its rotary axis upon the reciprocation of said rod.

A brush, comprising:

• a handle at one end;
• a brush head at the opposite end;
• a plurality of bristle holders each mounted for axial and rotary movement about a rotary axis within a socket in the brush head;
• spring means normally urging the bristle holders outwardly of their respective sockets but permitting inward axial movement of the bristle holders within their respective sockets during use of the brush;
• and a manually-operated drive for oscillating each bristle holder about its own rotary axis.
