KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Gegenstand der vorliegenden Erfindung ist ein ,Dämpfer für Fernsprechleitungen, welcher das Summen der Drähte und der Stangen verhmdern soll.The present invention is a damper for telephone lines, which the The purpose of this is to reduce the hum of the wires and the rods. Derselbe besteht aus einem auf den Draht geschobenen Kautschukcylinder a, welcher nur an seinen beiden Enden den Draht b fest umschliefst, in der Mitte aber frei läfst, zu welchem Zwecke der Cylinder innen bei c cylinderförmig ausgespart ist.It consists of a rubber cylinder a pushed onto the wire, which only tightly encloses the wire b at its two ends, but leaves free in the middle, for which purpose the cylinder is recessed in the form of a cylinder inside at c. Ein solcher innen ausgesparter Cylinder soll das Summen der Drähte weit vollkommener verhindern als die bisherigen vollen Cylinder. Dies haben Versuche bewiesen; eine theoretische Erklärung dafür steht noch aus.Such a cylinder, recessed inside, is said to make the humming of the wires far more perfect prevent than the previous full cylinder. Experiments have proven this; a theoretical one Explanation for this is still pending. Der Kautschuk kann auch durch einen anderen elastischen Stoff ersetzt werden.The rubber can also be replaced by another elastic material. Vortheilhaft bringt man in dem Cylinder einen Längsschlitz d an, der gestattet, den Cylinder an einen bereits gespannten Draht anzulegen.It is advantageous to make a longitudinal slot d in the cylinder, which allows the cylinder to be placed on an already tensioned wire. Um dem Cylinder das nöthige Gewicht zu geben, umgiebt man ihn vortheilhaft mit einem' Bleirohrstück c, welches bei f ebenfalls aufgeschnitten ist.In order to give the cylinder the necessary weight, it is advantageously surrounded by a piece of lead pipe c, which is also cut open at f. Pa te ν τ,-An spruch:Pa te ν τ, claim: Geräuschdämpfer für Fernsprechleitungen, bestehend aus einem Kautschukcylinder, der an den Enden den Draht fest umschliefst, in der Mitte aber eine cylindrische Aussparung c hat.Sound absorber for telephone lines, consisting of a rubber cylinder that tightly surrounds the wire at the ends, but has a cylindrical recess c in the middle.
