  • Patent number: 5592711
    Abstract: The paint brush apparatus having multiple painting widths is designed in order to provide the user with a paintbrush apparatus that is able to paint in a number of different pre-determined widths that will allow the user to more rapidly finish any painting project. The apparatus is comprised of a handle assembly having lengthwise holes to permit the handle to incorporate internal, movable drive shafts. The drive shafts have a control mechanism such as a slide button or thumbwheel that will allow the extension or retraction of one or both of the shafts. A bristle head assembly has the bush bristles attached and has at least one open slot cut therein. Separate brush inserts are inserted into the slots in the bristle head assembly and are attached to the drive shafts in the handle assembly. The inserts are designed to be constructed of material which will inhibit the sticking of the inserts due to dried paint or debris in the apparatus.
