    Abstract: The patent search disclosed many self-cleaning pet brushes. Most use a perforated pad over the bristles. Our method has a wire grill that sits flush with the base. It is held in place by hinges. A flipper button next to the handle flips the hair off into a waste container. This principle is applied to both the pet cleaner and the horse brush cleaner. Both the work grill for pet brush cleaning and the plate over the serrated blades for horse brush cleaning are held in place by a magnet (ear ring) type. This holds the grill and the plate in a firm position while in use. We found no self cleaning brushes for horses—only a hair shredder issued to a Allen Simon . . . U.S. Pat. No. D481-8365 Dated Nov. 14, 2003. The combination of a pet brush and a horse brush is unique and no patent has been found using this design.
