In 1890, black American inventor Daniel Johnson received a patent for "Grass Receivers for Lawn Mowers" (U.S. No. 429,629). This was an improvement on the inventor's own earlier patent application. It consists of a means for suspending the receiver from the mower-handle and enabling the weight of the receiver to be equally distributed. The side of the receiver is covered with woven wire netting. For the purpose of dumping the contents of the receiver, a sliding bottom is provided, operated with a foot stirrup. The patent application was signed by Daniel Johnson making his X mark with two witnesses adding their signatures.
