KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es hat sich gezeigt, daß die an den großen Zentralstationen für drahtlose Telegraphie zur Aufhängung der Sende- bzw. Fangdrähte errichteten Maste aus Eisengitterwerk trotz ihrer Isolierung vom Erdboden einen gewissen nachteiligen Einfluß auf die Vorgänge des TeIegraphierens ausüben, und daß diese schädigende Wirkung mit der neuerdings immer größeren Zunahme der Höhe derartiger MasteIt has been shown that the at the large central stations for wireless telegraphy for Suspension of the transmission or safety wires erected masts made of iron lattice work in spite of them Isolation from the ground has a certain detrimental effect on the processes of telegraphing exercise, and that this damaging effect with the lately ever greater increase in the height of such masts

ίο in gesteigertem Maße ebenfalls zugenommen hat. Die vorliegende Erfindung betrifft eine Einrichtung, durch welche dieser Übelstand beseitigt und damit die Möglichkeit geboten wird, den eisernen Masten eine beliebige Höhe geben zu können. Hierbei ist zu beachten, daß man bei der Herstellung derartiger Maste an die Gitterträgerkonstruktion in Eisen sowohl aus Festigkeitsgründen als auch aus wirtschaftlichen Rücksichten gebunden ist.ίο has also increased to a greater extent. The present invention relates to a device by which this inconvenience is eliminated and thus the possibility is offered to be able to give the iron masts any height. It should be noted that that one in the manufacture of such masts to the lattice girder construction in iron both is bound for reasons of strength as well as for economic considerations.

Der den Gegenstand vorliegender Erfindung bildende Gittermast ist dadurch gekennzeichnet, daß er nicht nur in an sich bekannter Weise unterteilt ist und daß seine Teile in ebenfalls an sich bekannter Weise voneinander elektrisch isoliert sind, sondern daß diese Einzelteile mittels einer auf der Isolierung der Unterteilungsstelle ruhenden Gelenkverbindung, z. B. eines Kugellagers, eines Tangentialkipplagers o. dgl., aufeinandergestellt sind und je für sich mittels in bekannter Art vom Erdboden isolierter Spanndrähte gehalten werden.The lattice mast forming the subject of the present invention is characterized in that it is not only subdivided in a manner known per se and that its parts are divided into are also electrically isolated from one another in a manner known per se, but that these Individual parts by means of a hinge connection resting on the insulation of the subdivision point, z. B. a ball bearing, a Tangentialkipplager o. The like., Are stacked and each held for itself by means of tension wires isolated from the ground in a known manner will.

Die beiliegende Zeichnung veranschaulicht beispielsweise in Fig. ι einen mehrfach unterteilten Mast, bei dem die einzelnen Teile mittels Kugellagers α aufeinanderstehen und durch geeignet gespannte, in bekannter Weise ebenfalls vom Erdboden isolierte Spanndrähte b in ihrer Lage erhalten werden.The accompanying drawing illustrates, for example, in Fig. Ι a multiply subdivided mast, in which the individual parts stand on top of one another by means of ball bearings α and are maintained in their position by suitably tensioned tensioning wires b which are also insulated from the ground in a known manner.

Fig. 2 veranschaulicht in größerem Maßstäbe die Kugellagerung und die zugehörige Isolierung, die in an sich bekannter Art aus mehreren übereinanderliegenden Glasplatten c besteht, die durch umgelegte Eisenringe d gegen seitliche Verschiebung gesichert sind.Fig. 2 illustrates on a larger scale the ball bearing and the associated insulation, which consists in a known manner of several superimposed glass plates c, which are secured against lateral displacement by folded iron rings d.

Auf der oberen Glasplatte ruht, letztere geeignet umspannend, die Grundplatte e für die Kugel, auf welche sich der geeignet ausgebildete Fuß f des nächst höheren Mastteiles stützt. The base plate e for the ball, on which the suitably designed foot f of the next higher mast part rests, rests on the upper glass plate, spanning the latter in a suitable manner.
