New sand-blasting helmet. Washington, D.C., Oct. 15. Protection against that dreaded disease Silieosis, is assured underground workers with this new sand-blasting helmet developed by William P. Biggs, Safety Engineer of the Navy Department Weighing only 43 ounces the helmet has been tested for nearly a year in various naval stations throughout the country.
Don't know the exact year though.:rolleyes:
Source: Library of Congress
 
Patent records may suggest/provide the year
It's October 15, 1936 as per detailed photo information.
And the disease mentioned in the text I posted with the photo is Silicosis. The mistake could be a typo by the Library or by the original source. I also wondered why a mask is called "helmet" but that's a different story.
