In 1912, Morgan developed another invention, much different from his hair straightener. Morgan called it a Safety Hood and patented it as a Breathing Device, but the world came to know it as a Gas Mask. The Safety Hood consisted of a hood worn over the head of a person from which emanated a tube which reached near the ground and allowed in clean air. The bottom of the tube was lined with a sponge type material that would help to filter the incoming air. Another tube existed which allowed the user to exhale air out of the device. Morgan intended the device to be used "to provide a portable attachment which will enable a fireman to enter a house filled with thick suffocating gases and smoke and to breathe freely for some time therein, and thereby enable him to perform his duties of saving life and valuables without danger to himself from suffocation. The device is also efficient and useful for protection to engineers, chemists and working men who are obliged to breathe noxious fumes or dust derived from the materials in which they are obliged to work."
The National Safety Device Company, with Morgan as its General Manager was set up to manufacture and sell the device and it was demonstrated at various exhibitions across the country. At the Second International Exposition of Safety and Sanitation, the device won first prize and Morgan was award a gold medal. While demonstrations were good for sales, the true test of the product would come only under real life circumstances.
That opportunity arose on July 24, 1916 when an explosion occurred in a tunnel being dug under Lake Erie by the Cleveland Water Works. The tunnel quickly filled with smoke, dust and poisonous gases and trapped 32 workers underground. They were feared lost because no means of safely entering and rescuing them was known. Fortunately someone at the scene remembered about Morgan's invention and ran to call him at his home where he was relaxing. Garrett and his brother Frank quickly arrived at the scene, donned the Safety Hood and entered the tunnel. After a heart wrenching delay, Garrett appeared from the tunnel carrying a survivor on his back as did his brother seconds later. The crowd erupted in a staggering applause and Garrett and Frank reentered the tunnel, this time joined by two other men. While they were unable to save all of the workers, the were able to rescue many who would otherwise have certainly died. Reaction to Morgan's device and his heroism quickly spread across the city and the country as newspapers picked up on the story. Morgan received a gold medal from a Cleveland citizens group as well as a medal from the International Association of Fire Engineers, which also made him an honorary member.
Although he could have relied on the income his Gas Masks generated, Morgan felt compelled to try to solve safety problems of the day. One day he witnessed a traffic accident when an automobile collided with a horse and carriage. The driver of the automobile was knocked unconscious and the horse had to be destroyed. He set out to develop a means of automatically directing traffic without the need of a policeman or worker present. He patented an automatic traffic signal which he said could be "operated for directing the flow of traffic" and providing a clear and unambiguous "visible indicator."
Satisfied with his efforts, Morgan sold the rights to his device to the General Electric Company for the astounding sum of $40,000.00 and it became the standard across the country. Today's modern traffic lights are based upon Morgan's original design.
