KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft einen leitenden Träger für elektrische Stromsammler, in welchen die wirksame Masse eingetragen wird, und verfolgt den Zweck, einerseits eine ausreichende elektrische Zuleitung zur wirksamen Masse zu scharfen, andererseits die wirksame Masse unter allen Umständen zu verhindern, aus dem leitenden Träger herauszufallen, wenn sie sich abwechselnd ausdehnt und zusammenzieht. The present invention relates to a conductive carrier for electrical current collectors, in which the effective mass is entered, and pursues the purpose, on the one hand, a sufficient To sharpen the electrical lead to the effective mass, on the other hand the effective To prevent ground at all costs from falling out of the conductive support, if it alternately expands and contracts.
In den Fig. 1, 2 und 3 ist der leitende Träger dargestellt. Das ganze Feld der Elektrode ist durch Stege s in einzelne Abtheilungen derart zerlegt, dafs diese Stege s die wirksame Masse schräg durchsetzen und so eine ä'ufserst günstige Stromzuleitung zur wirksamen Masse ermöglichen. Dabei sind die in paralleler Richtung verlaufenden Stege abwechselnd nach der einen und nach., der anderen Seite geneigt, ebenso die senkrecht zu diesen verlaufenden Stege. Die einzelnen Abtheilungen des Elektrodenfeldes bilden mithin Tetraeder, bei denen je die nach aufsen liegenden Kanten abgestutzt sind.In Figs. 1, 2 and 3 the conductive support is shown. The whole field of the electrode is divided by webs into individual divisions s so these webs DAF s enforce the effective mass obliquely, thereby allowing an ä'ufserst cheap current supply line to the effective mass. The webs running in the parallel direction are inclined alternately to one side and to the other, as are the webs running perpendicular to them. The individual sections of the electrode field therefore form tetrahedra, in which the edges lying on the outside are trimmed.
Zur Herstellung dieser Trägerformen dienen nun Gufs- bezw. Prefsformen, welche in den Fig. 4, 5, 6 und 7 der beiliegenden Zeichnung dargestellt sind.For the production of these carrier forms now Gufs- respectively. Prefsforms, which are in the Figures 4, 5, 6 and 7 of the accompanying drawings are shown.
An der einen Seite der Gufsform sitzen Vorsprünge a, welche nur an zwei Seiten sich keilförmig verjüngen, während die beiden anderen Seiten parallel und senkrecht zur Gufsformwand verlaufen. Um die, zweite keilige Abschrägung des Tetraeders zu erhalten, werden jedem Vorsprunge der vorgedachten Art entsprechend je zwei Prismenkörper b an der anderen Gufsformwand angeordnet, welche über den erstgedachten Vorsprung hinübergreifen. Auf diese Weise entstehen fast vollkommene Tetraeder mit abgestutzten Kanten als Vollkerne, zwischen denen die Zwischenräume verbleiben, in welche das Trägermaterial einfliefsen und so die Stege * des leitenden Trägers bilden kann. An je vier zusammenstofsenden Ecken der Hohlräume zur Aufnahme der wirksamen Masse bleiben vierkantige Säulchen (Fig. 1) stehen, welche dem ganzen Träger noch eine Widerstandsfähigkeit gegen Deformationen verleihen. Diese Säulchen können unbeschadet der Haltbarkeit des Trägers senkrecht zur Ebene der Elektrode durchbohrt werden (g-, Fig. 1), wodurch das todte Gewicht der Elektroden herabgedrückt wird. Es können aber zugleich diese Bohrungen benutzt werden, um Versteifungen zwischen den abwechselnd positiven und negativen Elektroden aus nichtleitenden Körpern anzuordnen, welche die Elektroden in sicherem Abstande von einander halten.On one side of the mold there are projections a, which only taper in a wedge shape on two sides, while the other two sides run parallel and perpendicular to the mold wall. To obtain the, second wedge-shaped chamfer of the tetrahedron, each of the projections preconceived type are corresponding two each prism body b on the other Gufsformwand arranged which encroach on the erstgedachten projection. In this way, almost perfect tetrahedra with trimmed edges are created as solid cores, between which the gaps remain, into which the carrier material can flow and thus form the webs * of the conductive carrier. Square columns (Fig. 1) remain on each of the four cohesive corners of the cavities for receiving the effective mass, which give the entire support a resistance to deformation. These columns can be pierced perpendicular to the plane of the electrode without prejudice to the durability of the carrier (g-, Fig. 1), whereby the dead weight of the electrodes is pressed down. At the same time, however, these bores can be used to arrange stiffeners between the alternating positive and negative electrodes made of non-conductive bodies, which keep the electrodes at a safe distance from one another.
