Definitions
- My invention relates to the use of glycerine for this purpose, and I carry out my invention as follows:
- the substances to be rendered impervious are first wrought into the desired form. When the articles are dry they are saturated with glycerine by immersion therein or by any process suitable therefor. This treatment renders them impervious to gas, preventing either its escape therefrom or penetration thereinto.

Be it known that I, ENOCH OSGOOD, of Boston, county of Sufi'olk andState of Massachusetts, have invented anew and Improved Process of BenderingLeather, Fibrous and Porous Materials Impervious to Gas, preventing all gases from penetrating or escaping from such materials when made into bags, tubes, or other forms;
My invention relates to the use of glycerine for this purpose, and I carry out my invention as follows: The substances to be rendered impervious are first wrought into the desired form. When the articles are dry they are saturated with glycerine by immersion therein or by any process suitable therefor. This treatment renders them impervious to gas, preventing either its escape therefrom or penetration thereinto.
If at any time any portion of the article should become injured or pervious to gas, by
reason of absorption of the glycerine by bodies Witnesses:
