Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand der vorliegenden Erfindung ist" ein Verfahren zur Herstellung von Elektrodenplatten für elektrische Sammler,, durch welches die Oberflächen derartiger Platten mit einer grofsen Zahl feiner, dicht an einander gereihter und gleichmäfsig vertheilter Erhöhungen versehen werden, welche von der Säure frei umspielt und daher beim Formiren rasch in active Masse umgewandelt werden können.The subject of the present invention is "a process for the production of electrode plates for electrical collectors" by which the surfaces of such plates with a great number of finer, closely lined up and evenly distributed elevations, which the acid plays around freely and can therefore be rapidly converted into active mass when forming.

Um stärkere Bleiplatten auf beiden Seiten gleichzeitig mit mehrere Millimeter tiefen Einschnitten in der Weise herzustellen, dafs die Platten mit dicht an einander gereihten Spitzen versehen erscheinen und ein bürstenartiges Aussehen erhalten, bedarf es einer Vorrichtung, deren Schneidwerkzeuge genau gegen einander arbeiten und gleichzeitig eine gleichförmige Arbeit liefern. Dies läfst sich nur mittelst eines Walzenpaares erreichen, von dessen Walzen die eine an ihrer Oberfläche mit rechtsgängigem, die andere mit linksgängigem messerscharfen Gewinde versehen ist. Derartige Walzen sind nicht allein rasch und solid, sondern auch mit grofser Genauigkeit herstellbar, bieten, da sie compact und fest sind, dem grofsen Drucke genügenden Widerstand und arbeiten, wenn richtig eingestellt, sehr genau gegen einander. Die messerscharfen Gewinde bedürfen zum Schärfen nur wenig Zeit und Arbeit und der Durchmesser der Walzen bleibt überall genau gleich.To make thicker lead plates on both sides at the same time with several millimeter deep cuts to be produced in such a way that the plates with tips closely lined up with one another appear provided and have a brush-like appearance, a device is required whose cutting tools work exactly against each other and at the same time a uniform Deliver work. This can only be achieved by means of a pair of rollers, one of its rollers the one on its surface with right-handed, the other with left-handed razor-sharp Thread is provided. Such rollers are not only fast and solid, but also with They can be produced with great accuracy and, since they are compact and solid, offer great prints sufficient resistance and, if set correctly, work very precisely against each other. The razor-sharp threads require little time and work to sharpen The diameter of the rollers remains exactly the same everywhere.

Nach diesem Verfahren wird die Bleiplatte, aus welcher die Sammlerelektrode hergestellt werden soll, zwischen den beiden mit scharfen, messerartig wirkenden Schraubengewinden versehenen rotirenden harten Stahlwalzen hindurchgeführt, und diese Operation wird, je nachdem feinere oder gröbere Erhöhungen hergestellt werden sollen, mehr oder weniger oft und unter jedesmaliger Aenderung der Lage der Platte wiederholt.The lead plate, from which the collector electrode is made, is made using this process between the two with sharp, knife-like acting screw threads rotating hard steel rollers, and this operation is carried out as the case may be finer or coarser elevations should be made, more or less often and repeated changing the position of the plate each time.

Auf diese Weise können die Platten auf beiden Seiten gleichzeitig auf mehrere Millimeter Tiefe der Säure zugänglich gemacht werden, während der stegartige, intact bleibende Mitteltheil der Platte den Leiter für jede einzelne der Erhöhungen oder Spitzen bildet.In this way, the panels can be several millimeters on both sides at the same time Depth of the acid can be made accessible, while the web-like, remaining intact The middle part of the plate forms the ladder for each of the ridges or peaks.

Bei den letzten zwei im rechten Winkel sich kreuzenden Durchgängen wird vermittelst der Walzen ein Netz von tieferen Einschnitten auf der Platte hervorgebracht, durch welche Einschnitte die in sehr grofser Zahl vorhandenen feinen und spitzen Erhöhungen in kleine Gruppen geschieden werden.The last two passages that cross each other at right angles are used as an intermediary Rolling produced a network of deeper incisions on the plate, through which incisions the fine and pointed elevations, which are present in very large numbers, are divided into small groups.

Auf beiliegender Zeichnung stellt Fig. 1 den Querschnitt und Fig. 2 die Ansicht eines Stückes einer derartig hergestellten Elektrodenplatte α dar, welche in angegebener Weise mit einer grofsen Zahl von Erhöhungen b versehen ist, die durch die sich kreuzenden Einschnitte c in Gruppen von rechteckiger oder rhomboedrischer Umrifsform geschieden sind.In the accompanying drawing, FIG. 1 shows the cross-section and FIG. 2 shows the view of a piece of an electrode plate α produced in this way, which is provided in the specified manner with a large number of elevations b , which are formed by the intersecting incisions c in groups of rectangular or rhombohedral outline form are divorced.
