Gas maskIn 1850, the first U.S. patent No. 7,476 for a gas mask with a self-contained breathing apparatus was issued to Benjamin J. Lane of Cambridge, Mass. for a "respiring apparatus." (The first U.S. patent for an "inhaler or lung protector" resembling a gas mask of the modern type was awarded to Lewis Phectic Haslett of Louisville, Ky., on 12 Jun 1849. It had a filter of woolen fabric or other porous substance to purify the air and remove dust.) |
