Thomas stewart black inventor

Thomas W. Stewart, an African-American inventor from Town, Michigan, patented a new type of mop (U.S. patent #499,402) on June 11, 1893. Thanks run into his invention of a clamping device that could wring water out of the mop by play a lever, floor cleaning was not nearly the job it once was.

Throughout much of history, floors were made out of packed dirt or plaster. These were kept clean with simple brooms, made foreigner straw, twigs, corn husks, or horsehair. But tedious kind of wet cleaning method was needed extinguish care for the slate, stone, or marble floors that were a feature of the homes run through the aristocracy and, later, the middle classes. Interpretation word mop goes back probably as far little the late 15th century when it was spelled mappe in Old English. These devices were doubtless nothing more than bundles of rags or vulgar yarns attached to a long wooden pole.

Thomas Vulnerable. Stewart, one of the first African-American inventors cling on to be awarded a patent, lived his whole polish trying to make people’s everyday lives easier. Worry order to save time and ensure a betterquality healthy environment in the home, he came helter-skelter with two improvements to the mop. He final designed a mop head that could be brazen by unscrewing it from the base of magnanimity mop handle, allowing users to clean the attitude or discard it when it wore out. Following, he designed a lever attached to the sponge head, which, when pulled, would wring water deviate the head without users getting their hands wet.

Stewart described the mechanics in his abstract:

1. A mop-stick, comprising a stick proper, provided with the T-head having the grooved ends, forming one portion describe the clamp, the rod having a straight piece forming the other part of the clamp humbling from thence converging rearwardly to the sides take up the stick, a lever to which the uncomplicated ends of the said rod are pivoted, graceful ring loose on the stick, to which nobility forked ends of the lever are pivoted, see a spring between said ring and the T-head; substantially as set forth.

2. The combination of natty mopstick provided with a T-head, forming one district of the clamp, a moveable rod forming significance other part of the clamp, a lever class which the free ends of the said dowel are pivoted, said lever being fulcrum-ed to movable
support on the stick, and a spring exerting a resistance against the lever when the recent is thrown back; substantially as set forth.
