Description

Patented June 24, 1924.
PATENT OFFICE.
CAMPBELL C. CARPENTER, O'F NIAGARA FALLS, NEW YORK, ASSIGNOR TO U. S. LIGHT & T CORPORATION, OF NIAGARA FALLS, NEW YORK, A CORPORATION OF NEW TREATMENT OF WOOD SEPARATORS.
No Drawing.
To all whom it may concern:
Be it known that I, CAMPBELL C. CAR- PENTER, a citizen of the United States, residing at Nia ara Falls, in the county of Niagara and tate of New York, have invented new and useful Improvements in the Treatment of Wood Separators, of which the following is a specification.
This invention relates to the treatment of Wood separators for stora e batteries.
An object of the invent1on is to so treat a Wood separator as to get the fibres of the wood in proper colloidal condition so as to more readily absorb and transfer sulphuric acid and so as to more readily diffuse battery acid.
A further object is to so prepare the separator that it will not be readily attacked by battery electrolyte, thereby increasing the separator life.
When the wood of the se arator is in proper colloidal condition, it as the property of absorbing acid of greater density than that of the elertrolyte surrounding it.
This increases the conductivity of the separator.
In the process as outlined below, exact proportions and periodsof time have been iven as re resenting the best practice so far etermine but it is not intended that the stated proportions and time periods shall be construed as otherwise than illustrating Application filed June 21, 1923. Serial No. 646,988.
the principles of the process, it being understood that variations in proportions and details of treatment may be resorted to Without departing from the principles of the invention as defined in the appended claims.
In the process herein described, Port Orford cedar has been employed, since it has been found that this wood is specially adapted for the manufacture of separators.
In carrying out the process, the separators cut to size, are placed in a supersaturated solution of lime and subjected to a pressure of thirty pounds er square inch or over in the presence of S8 gas and heated for a period of approximately five hours.
lVhat I claim as new and desire to secure by Letters Patent of the United States is C. C. CARPENTER.
