US Patent 10034455 Self-cleaning pet grooming implement

An implement for grooming hair of an animal has a comb support and an array of tines mounted in the comb support. The array has a plurality of generally parallel combs, and each comb has a set of regularly spaced generally parallel tines of similar size. In one aspect, the spacing between adjacent tines of a selected comb varies depending on the location of the comb along a longitudinal axis. In this aspect, as the comb support is drawn to effectuate the grooming of the hair of the animal, hair at the selected location experiences a progression in at least three stages from coarse to more finely spaced tines.
