Abstract

239,478. Rushen, P. C., (Siemens & Halske Akt.-Ges.). Feb. 13, 1925. Hearing-appliances.- A device for connecting a telephone or listening-tube to the ear comprises a bow-shaped part 6 adapted to be engaged by parts of the shell of the ear and so retained in position, and a part 1 adapted to fit the orifice of the meatus. The telephone or tube is attached to a sleeve 5 passing through the part 1. The bow 6 is mounted on an angularly arranged pin 7 on the part 1, and the device may be adapted for use with either ear by adjusting the parts 1, 6 relatively to one another.
