KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf einen Lampenzug, bei welchem ein den Beleuchtungskörper tragendes Rohr zwischen zwei Rollen mit regelbarer Pressung eingestellt wird. Bei den bisher bekannten Lampenzügen dieser Art wurden die Rollen mittelbar oder unmittelbar durch Vermittlung einer Feder gegen das Rohr angepreßt. Die nach kurzer Zeit nachlassende Federspannung macht ein häufiges Nachstellen erforderlich. Trotzdem ist immer die Möglichkeit gegeben, daß sich die Lampe von selbst senkt, oder daß durch öfteres Nachspannen der Federn von ungeübter Hand das Rohr so fest eingeklemmt wird, daß es sich nicht mehr ziehen läßt.The invention relates to a lamp train, in which a lighting fixture supporting pipe is set between two rollers with adjustable pressure. at the previously known lamp trains of this type were the roles directly or indirectly pressed against the tube by means of a spring. The one that subsides after a short time Spring tension makes frequent readjustments necessary. Nevertheless there is always the possibility that the lamp lowers by itself, or that by repeatedly tightening the springs by an inexperienced hand that The pipe is clamped so tightly that it can no longer be pulled.
Um diese Nachteile zu vermeiden, werden gemäß der Erfindung alle Federn ausgeschaltet und der Druck der Rollen gegen das Rohr lediglich durch Schrauben geregelt, welche die Flansche eines aus einem Stück bestehenden, die Rollenlager bildenden Bügels zusammenziehen. Der Bügel ist dabei unmittelbar an der Stopfbüchse des Rohres befestigt. In order to avoid these disadvantages, all springs are switched off according to the invention and the pressure of the rollers against the tube is regulated only by screws, which make the flanges one-piece pull together existing bracket forming the roller bearing. The bracket is immediate attached to the stuffing box of the pipe.
Diese Bauart bietet neben sehr billiger Herstellung den Vorteil, daß das die Lampe tragende Rohr nach einmaligem Einstellen der Klemmschrauben dauernd so eingespannt bleibt, daß die Lampe leicht auf und ab geschoben werden kann, jedoch niemals von selbst herunterrutscht.In addition to being very inexpensive to manufacture, this type of construction has the advantage that it is the lamp The load-bearing pipe is permanently clamped in this way after the clamping screws have been adjusted once remains that the lamp can easily be pushed up and down, but never by slides down himself.

Der Bügel α wird unmittelbar unter einem Schraubstück b eingeklemmt, welches ihn mit der Stopfbüchse c derart verbindet, daß die Arme d des Bügels so kurz wie möglich gehalten werden können. Die an die Arme d anschließenden Gabeln e sind mit seitlichen Lappen f versehen, durch welche Schrauben g gehen, mittels welcher die Rollen h gegen das Rohr i gepreßt werden.The bracket α is clamped directly under a screw piece b , which connects it to the stuffing box c in such a way that the arms d of the bracket can be kept as short as possible. The forks e adjoining the arms d are provided with lateral tabs f through which screws g go, by means of which the rollers h are pressed against the tube i.
