The Talking Machine Forum — For All Antique Phonographs & Recordings

hello folks.
I have run across this "Electrip" device/accessory from Edison. Can you help me understand what it is used for?

Thanks

Apparently it was for dictating machines. From the National Park Service https://npgallery.nps.gov/EDIS/AssetDet ... 4d6426e74b

Thank You
