OKLAHOMA', OKLAHOMA ciw, OKLAHOMA' Banen This. invention relates to certain new-fand useful improvements' in brushes and more :particularly to tooth-brushes., and it has for its ob] ect, among others, to provide a brush of this general character-'in which the brush or Y bristle portion shall bc readily detachable .so that the handle, which. less expensive nature,
from the handle, may be of a more or may be usedfory an indefinite period with renewable brush ends.
A further object of the invention is to provide a brush of this character 'hich shall be l in which the thereof will be hardly disfroin the brush novel features cern'ible soas to not detract as an entirety. a Y Other objects and advantages of the invention will hereinafter appear,.and the novel features thereof will be pointed out in*l the appendedclaim'. f
