METHOD OF CONSTRUCTING ELECTRODE FRAMES FOR SECONDARY VOLTAIC BATTERIES
Year: 1885

I, ACHILLES KHOTINSKY of N° 67 Maaskade, Rotterdam in the Kingdom of
Holland, Engineer, do hereby declare the nature of my invention for METHOD
OF CONSTRUCTING ELECTRODE FRAMES FOR SECONDARY VOLTAIC BATTERIES to be
as follows:-
"
My invention relates to a method of constructing frames suitable for holding
the pulverulent, or pasty material, such as oxides of lead, employed in secondary
electric batteries. I construct these as I will describe referring to the accompanying
drawings. Fig. 1 is a section of a frame suitable for the positive electrode at either
end of a battery cell. Fig. 2 is a section of a frame suitable for the other positive
electrodes throughout the cell, presenting both sides open with separating plate
between. Fig. 3 is a section and Fig. 4 is a plan of frame for negative electrode,
presenting both sides open without separating plate. In constructing such frames
I force lead or other suitable metal in a condition softened by heat through dies of
the required shape, in a manner similar to that in which lead pipes are formed.
When the bars of the frame are separately moulded as in Fig. 3, I lay them side by
side and cast or solder on to their ends pieces a a as shewn in Fig. 4. The recesses
presented between the ribs of the frames are filled up with the electrode material,
which the inwardly projecting lips of the ribs prevent from becoming displaced.
Obviously the forms of these recesses may be varied, so long as the ribs or partitions
which separate them are made with inwardly projecting lips or flanges to prevent
displacement of the material with which the recesses are charged.

I, ACHILLES KHOTINSKY, of N° 67 Maaskade, Rotterdam in the Kingdom of
Holland, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
The herein described method of constructing electrode frames for secondary
voltaic batteries by forcing soft lead or other suitable metal in continuous lengths
through dies shaped to the transverse section of the frame.
