UNITED STATES PATENT orrlcs.
PAUL MALLON, OF PARIS, FRANCE, ASSIGNOR TO THE SOCIETE 'D PARVILLE & CIR, OF PARIS, FRANCE.
Application filed December 16, 1927, Serial No. 240,562, and in France December 11, 1926.
My inventionv relates to storage batteries, and chiefly to separating pieces for such batteries, which consist of partitions provid ed with slots or groups of slots which are permanently open.
The present invention has for its object the manufacture of such separating or spacing pieces by a process which is economical as regards both the labor and material, and by its use a substantial construction can be obtained.
According to our invention, the electrodes are not mounted by the use of distinct spacing pieces, but herein we employ a single spacing block or device which comprises suitable recesses for the electrodes as well as slots formed in the block; said slots are close together, and the said block is made, rigid by a middle rib which is parallel with the axis of the channels and extends between the two narrow faces of the block in the intervals between the channels.
The said spacing blocks may consist of any suitable insulating material, comprising wood in the natural state or impregnated .with an insulating and hardening substance, treated pasteboard or paper, agglomerated wood products, and the like.
The slots may be perpendicular or inclined wilth reference to the axes of the said channe s.
The individual blocks may have a height equal to the length of the electrodes or a less height, and in this event they may be superposed in the proper number corresponding to the height of the plate in use; they may be obtained either directly by cutting, by means of suitable tools, or by supel'posing cut out sheetsof material, shaped accm'ding to a template or in like manner, thesebeing piled up with the interposition of other cutout sheets which may be cemented'orotherwise secured to the main sheets, and will form the rib between two adjacent cylindrical electrodes. This rib may also consist of an insulating rod which. is inserted through the sheets, or of any other device.
The said separating or spacing blocks may be manufactured by the use of plastic insulating substances, by casting it in a mold which is sodisposed as to form the ,p
sheets or plates which are spaced apart and are perpendicular to the axes of the channels, or inclined from the latter, as well as the ribs between the channels.
The appended drawings, illustrating the descriptiomare given by way of example.
b Fig. 1 is a plan view of a separating mem- Fig. 2 is a corresponding longitudinal section on the line 11-11 of Fig. 1.
Fig. 3 is a corresponding cross section on the line ]IIIII of Fig. 1.
Fig, 4 is a cross section of a modified construction.
Figs. 5 and 6 are respective views in plan and in horizontal section of another construction.
In the construction shown in Figs. 1 to 3, the separating device consists of acne piece member 1, pierced with various cylindrlcal recesses 2 adapted to contain the electrodes, it has also formed therein the horizontal slots 3 which extend upon only a part of the horizontal section of the said memher, so as to leave the stronger parts 4 whereby the whole will be made rigid.
In the case of Fig. 1, the device comprises a solid vertical part extending between the two successive recesses 2 whose outline is shown in horizontal projection at a b c (l. The grooves .5 parallel with the main faces of the device are formed at intervals so as to provide channels for the circulation of the liquid. 7 In the modification shown in Fig. 4, the slots are not horizontal but are inclined; this form has the particular advantage consisting in the fact that the particles of the active material detached from the electrodes will not fall, but will be held. by gravity in the bottom of the slots.
In the modification shown in Fi 5, the slots are not formed by saw cuts in t e piece, but are formed by the superposition of horizontal plates 6 extending for the whole length, between which are placed the spacing strips 7 of the proper thickness. The whole is cemented together, and the device may be strengthened by any other securin means.
The-invention is further applica le to sepagating i devices" for flat storage battery ates. I
Obviously, the several'constructions herein described and represented are given sole- 1y by way of example, and do not limit the present invention.
aving now particularly described my invention and in What manner the same is to be performed, I claim as my invention:
1. A separating device for storage batteries comprising an insulating block having a longitudinal series of passages extending depthwise, forming receivers for rods of active material, said block being formed with lateral grooves on opposite sides intersecting said passages but of such depth as to fall short of meeting between said passages, lea-ving ungrooved supporting portions between said passages.
2. A separating device for storage batteries comprising a laminated insulating block, the laminae being superposed and in contact, in a depth direction, said block having a longitudinal series of passages extendmg depthwise, forming receivers for rods of active material, alternate lamlnae being of such size as to overhang the adjacent laminae, forming grooves on opposite sides, of such depth as to intersect said passages.
3. A separating device for storage batteries comprising a laminated insulating block, the laminae being superposed and in contact, in a depth direction, said block having a longitudinal series of passages extending depthwise, forming receivers for rods of active material, alternate laminae being of such size as to overhang the adjacent laminae, forming grooves on opposite sides, intersecting said passages but of such depth as to fall short of meeting between said passages. leaving ungrooved supporting portions between said passages.
