INTERMEDIATE STATION. for

Bie! Firing concerns an intermediate station for links Conveyor belts * "in which the movement of the cross strand on the lower run of the drive link chain by means of an or "several consecutive Sprockets are transferred »whose teeth are articulated are used in the sprocket *

Difficulties have arisen with the "previously common designs" in operation result from this * that the sprocket teeth run out of the chain under friction between Tooth flank and Xaschenkettebolzen goes on, which is particularly special with link conveyor belts Difficulties are caused by the fact that there is a large conveyor belt under certain circumstances goalkeeper and backward running "can be used *

This difficulty is avoided in accordance with the increase in price by the fact that the teeth of the chain wheels are mounted in the body so that they can pivot out of their radial central position on both sides and close in the tooth base. Both sides of the tooth center line a'e a pressure surface, ζ3 * a pressure toIIe _{1 is} provided, which run along a stationary sirve disc known per se for linear operation of chains for the control of the teeth, which for the present 53 / 2418 FaIX is designed in such a way that at the start of Hz / 2n * of the engagement in the chain the teeth can move in the direction of rotation »

The firing is explained below using an example of a guide. In FIGS . 1 and 2, one of the chain wheels of an intermediate station is shown in elevation and in section.
