  • Patent number: 4974279
    Abstract: A back brush apparatus is provided with a flexible, helically wound wire core coaxially arranged through the brush containing a series of three separate sets of bristles, each randomly arranged with one another throughout the brush matrix defining a cylinder about the wire core. The first longest series of bristles are of a relatively soft character with the shortest and third series of bristles being of the stiffest character, with the second series of bristles being of intermediate length and stiffness relative to the first and third series. A hand loop is secured to a loop formed at each terminal end of the wire core and secured to the wire loop by means of a fastener to enable reciprocating the brush during use by an individual.
