Description

WILLIAM MORRISON, OF CHICAGO, ILLINOIS, ASSIGNOR TO VESTA ACCUMULATOR v COMPANY, A CORPORATION OF INDIANA.
WOOD SEPARATOR FOR STORAGE-BATTERY PLATES.
T223fi8.
No Drawing.
To all whom it may concern:
Be it known that 1, WILLIAM MORRISON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wood Separators for Storage-Battery Plates, of which the following is a specification.
My invention relates to wood separators for storage battery plates and the process of making the same.
The preferred method of making my improved separators consists in immersing the wooden plates in a hot solution of barium hydroxid and allowing them to remain therein until the solution has impregnated the wood. I then immerse the impregnated plates in a sulfate solution, such as a sulfuric acid solution, whereby sulfate of barium is precipitated in the pores of the wood. The plates are then Washed in water.
As the result of this treatment, the pores of the wood are filled to a large degree with the precipitated barium salt. The excessive porosity of wood separators, which permits treeing to occur in the battery, is thus corrected, without materially aifecting the internal resistance of the battery.
Specification of Letters Patent.
Patented May 29, 1917..
Application filed November 11, 1916. Serial No. 130,877.
While I have described barium sulfate as the salt which I prefer to use, other salts of barium, substantially insoluble in the battery electrolyte may obviously be used, these salts being precipitated from the barium hydroxid by the appropriate reagent.
I claim 1. A wood separator impregnated with barium sulfate.
2. A method of treating wood separators, which consists in treating them with a solution of barium hydroxid and then converting the barium hydroxid into barium sulfate.
3. The method of treating wood separators, which consists in treating them with a solution of barium hydroxid and then subjecting the treated separators to the action of sulfuric acid.
4. The method of treating wood separators which consists in producing in the pores thereof an insoluble barium compound.
5. A wood separator impregnated with an insoluble barium compound.
6. A wood separator having in its pores an insoluble barium compound.
In testimony whereof I affix my signature in presence of two witnesses.
WILLIAM MORRISON.
It is hereby certified that the State of incorporation of the assignee Letters Patent No. 1,228,368, granted May 29, 1917, upon the application of William Morrison, of Chicago, Illinois, for an irnprovementin Wood-Separators ior Storage- Battery Plates, was erroneously given as lndiana, whereas said State should have been given as Illinois, as shown by the records of assignments in this ofiice and thatthe said Letters Patent should be read with this correction therein that the same may conform to the record of the case in the Patent Office.
Signed and sealed this 22d day of October, A. D., 1918.
