KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die bisher verwendeten Separatoren bestanden in der Regel aus schwachen Hartgummiplatten, die durch Wellung die zum Auseinanderhalten der Akkumulatorenplatten erforderliche Stärke erhielten. Ferner wurden dieselben perforiert, um einen ausreichenden Säureumlauf zu ermöglichen.The separators used so far usually consisted of weak hard rubber plates, the corrugation required to hold the battery plates apart Got strength. They were also perforated to allow sufficient acid circulation to enable.
Bei bekannten amerikanischen Ausführungen werden die Hartgummiplatten mit Schlitzen ίο versehen und die zwischen den letzteren befindlichen Flächen abwechselnd nach beiden Seiten herausgedrückt.In known American designs, the hard rubber plates are made with slots ίο provided and the surfaces located between the latter alternately after both Pages pushed out.
Der Materialverbrauch und die Herstellungskosten aller dieser Separatoren sind verhältnismäßig groß, wenn auch die amerikanische Ausführung gegenüber der zuerst erwähnten geringe Vorteile in bezug auf den Materialverbrauch bietet.The material consumption and the manufacturing costs of all these separators are proportionate large, even if the American version has slight advantages over the first mentioned in terms of material consumption offers.
Nach der vorliegenden Erfindung werden dünne Platten mit Schlitzen versehen, entsprechend Fig. i. Darauf werden die Platten quer zu den Schlitzen auseinandergezogen, wodurch sich ein Netz nach Art der Fig. 2 bildet. Die zwischen den Schlitzen befindlichen Streifen ändern dabei ihre Lage so, daß die Separatoren die zum Auseinanderhalten der Akkumulatorenplatten erforderliche Stärke erhalten (Schnitt a-b). According to the present invention, thin plates are provided with slots, as shown in FIG. The plates are then pulled apart transversely to the slots, as a result of which a network in the manner of FIG. 2 is formed. The strips located between the slots change their position so that the separators are given the strength required to hold the accumulator plates apart (cut off).
Bei Separatoren nach dieser Erfindung wird bedeutend weniger Material gebraucht als bei den bisher bekannten; auch gegenüber der angeführten amerikanischen Ausführungsart ist die Materialersparnis bedeutend. Ferner ist die Herstellung wesentlich einfacher. Weitere Vorteile des neuen Separators sind Verringerung des Akkumulatorgewichts und die Erleichterung des Säureumlaufs.In separators according to this invention, significantly less material is used than in the previously known; is also opposite to the listed American version the material savings are significant. Furthermore, the production is much easier. Further The advantages of the new separator are reduced battery weight and ease of use of the acid circulation.
