Patent for a new and improved blacking brush. This design utilizes springs to move a blacking brush to and from a can of polish. This results in "evenness of wear of the bristles of the brush, economy of blacking, absence of spattering while extracting the blacking from the box, convenience in substituting the circular brush as a lid for the box in case of loss of the box-lid, and the saving of time in looking for a blacking-brush and a blacking-box separately" (lines 53-60).
