This is a Telefunken Tikker (or Schleifer)-type Wireless Detector circa 1914 which is used to receive Continuous Wave (CW) signals. It operates by rotating a Brass disk using a clockwork mechanism while trailing or dragging a Gold wire on the Brass disk as the disk rotates. The clockwork is similar to that used in a Marconi Magnetic Detector. In this case, when a CW signal is being received, a “grinding” noise is heard in the phones. Thus it was sometimes referred to as a Grinder instead of a Tikker. However, this detector falls into the Tikker class of wireless detectors.
The 1919 Telefunken catalog refers to these units as "clockwork sliders", in the original English translation.
Sliders were introduced to enable the receivers of the Telefunken singing-spark system (Löschfunken-Stationen) to receive continuous wave signals, being used in place of the crystal detector. This became necessary after Poulsen arc stations were acquired by military forces in Germany and Austria, around 1908.
Sliders and Tikkers were abandoned after reliable heterodyne oscillators with vacuum tubes became available during WW1.
